The spinning process flow selected in the present invention:

(1) Dyed cotton fiber: FA002 automatic plucking machine → FA022 multi-composite blending machine → FA106 porcupine opener → FA046 vibrating cotton box feeder → FA141A single hand lapping machine → FA201B carding machine;

(2) Dyed wood fiber and spun silk → FA002 automatic plucking machine → ZFA026 automatic cotton blender → FA106A card needle opener → FA046A vibrating cotton box feeder → FA141A single beater lapping machine → FA201B carding machine;

The production technology of each operation of spinning among the present invention:

(1) Dyeing and pretreatment of fibers

Cotton and fiber dyed by external processing, to minimize the color difference of the fiber, the strength of the dyed fiber is reduced, and the fiber is hardened. In order to improve its spinnability and uniform mixing, the cotton feeding machine is used to pre-open the colored fiber After mixing with the wool machine, it is evenly wetted, and 0.3% oil agent is added, and it is stuffed for 24 hours, so that the moisture regain of the colored cotton fiber reaches 8.5%-9.0%. Wood fiber absorbs moisture quickly and dehumidifies quickly, and it is easy to generate static electricity during production. It is necessary to add 0.6% antistatic agent, and the moisture regain will reach 11.5-12.5%, so as to ensure that it is in a state of dehumidification during the entire spinning process.

In order to reduce the tendency of spun silk to generate static electricity during the spinning process and the phenomenon of winding machine parts, the formula of 0.6% antistatic agent, 0.2% water-soluble silicone oil, 0.5% flat plus, and 10% water is used to spray evenly and keep it moist for 24 hours. , The moisture regain is controlled at 12%-13% to improve its spinnability. The moisture regain of dyed cashmere fiber reaches 15-16%.

Here, the carding process and spinning process of colored cotton fibers are omitted, and only the carding process of wood fiber and spun silk and the subsequent spinning process will be introduced below.

(2) Process measures for opening and cleaning cotton

The spun silk is thin and soft, with many silk and hair particles, and it is not easy to remove. The process principle of "grasping frequently and less grasping, combing more and beating less, mixing evenly, falling early, low speed, and anti-sticking" is adopted to properly enlarge the dust. The distance between the rods is 7-9mm. Beater speed should be appropriately reduced, among which ZFA026 automatic cotton blending machine beater speed is designed according to the minimum, FA106A card needle opener beater speed is 460-540r/min, FA046A vibrating cotton box feeder corner nail cord speed is 30-50m/min, The distance between the cotton equalizing roller and the corner nail curtain is 9-11mm, the FA141A single lapping machine card beater speed is 600-800rpm, the lap roller speed is 11-13r/min; the balance roller and the comb needle beater distance is 11-13mm, The pre-opened and mixed dyed wood fiber and spun silk are relatively fluffy, the basis weight of the cotton lap is 350-400g/m, and the length of the cotton lap is 25-30m. The relative humidity of the environment is controlled at 65%~70%.

(3) Carding process measures

Spun silk fiber is soft, smooth and long, with low strength, easy to break and form short pile during carding process, and blended with dyed wood fiber, the poor cohesion between fibers and the generation of static electricity will cause floating ends, holes, and rotten edges in the cotton web In case of poor web formation, the carding adopts the process principle of "four fronts and one accuracy, low speed, large gauge, and high speed ratio", increases the tension of the cotton web and installs a guide apron device, on the basis of avoiding fiber damage Improve the carding effect, reduce rubbing back, realize fast and good fiber transfer, and improve the quality of cotton web and raw sliver. Cylinder card clothing AC2520×01850, doffer card clothing AD4030×01890, cover card clothing MCC36. Adjust the cylinder-cover gauge to 0.35mm, 0.33mm, 0.30mm, 0.30mm, 0.33mm, enlarge the feed plate-licker-in roller gauge to 0.2-0.4mm, and cylinder-doffer gauge to 0.1-0.3mm , cylinder speed 280-320rpm, licker-in speed 600-650rpm, raw sliver weight control at 18-22g/5m, raw sliver delivery speed 70-85m/min. The relative humidity of the environment is controlled at 65%-70%. Sliver quality control range: neps 30-40 grains/g.

(4) Drawing process measures

In order to improve the color mixing uniformity of color spinning and ensure the uniform mixing and accurate mixing ratio of various components, the drawing process adopts three steps. Because the cashmere in the melange yarn has a large degree of curl, good fiber elasticity, and good cohesion, the drawing process mainly focuses on improving the parallelism of the fibers and improving the evenness of the cooked sliver. The "light weight, slow speed, and large separation distance, heavy pressure" process principle. Properly reduce the speed of the vehicle, use soft elastic rubber rollers treated with composite coatings and increase the pressure to prevent winding roller rubber rollers. The drawing head and the second pass adopt parallel drafting, which is beneficial to the straightening of the fiber. The channel should be smooth and clean. Because the cashmere slivers are relatively fluffy, 6-8 slivers are combined, including 2-3 colored cotton raw slivers, the weight of which is 19-23g/5m, 3-4 colored raw slivers of wood fiber/spun silk, and cashmere dyed slivers 1 root, and the relative humidity of the environment is controlled at 65-70%. (5) Roving process measures The roving process is mainly to further improve the degree of parallel separation of fiber straightening, improve evenness and control elongation. The roving process adopts the process principle of "heavy pressure, low speed, light weight, small tension, and large twist". Large axial winding density reduces accidental tension and end breaks during unwinding of the spun yarn. The twist coefficient of the roving is too large to control, and the smaller roving tension is used, which is conducive to the cohesion of fibers in the sliver, preventing the roving from being accidentally elongated and causing fine details, and is conducive to improving the drafting quality of the spun yarn. Give full play to the leading role of the main drafting zone, and use a small gauge when the draft can be opened, which is beneficial to control the floating fibers. Proper enlargement of the distance in the rear area can ensure that the fibers are fully straightened in the rear area and reduce fiber damage. Baker rubber rollers treated with antistatic agents are used. The main process parameters are configured as follows: roving basis weight is 3.0-4.0g/10m, roller gauge is (10-15)×(20-30)×(30-40)mm, rear draft is 1.1-1.5 times, twist The coefficient is 80-100, the spindle speed is 600-800rpm, and the original gap between the jaws is 4.0-5.0mm.

(6) Soft and Clean Spinning Positioning Spinning Technology and Process Optimization of Soft and Clean Spinning Colored Yarn

Knitting yarn requires uniform dryness and less hairiness. The soft and clean spinning technology transformed from ring-spinning cotton spinning equipment is to apply a fiber smoothing treatment surface in the triangle area of ordinary ring-spinning spinning, and form a soft yarn in the yarn-forming triangle area. Many fiber holding points, these fiber holding points have a good holding effect on the exposed fiber head end, and cooperate with the twisting rotation force and the sliver traction force to effectively transfer the exposed fiber into the yarn body, reducing the yarn Thread surface hairiness improves finish. Through the action of heat and humidity, the fibers are softened, the bending stress of the fibers is greatly reduced, and the exposed long fibers are twisted, twisted and moved into the yarn body to eliminate or greatly reduce yarn hairiness. In the spinning process of soft and clean spinning, the technological principle of "low speed, small back draft, large twist coefficient, and large roving moisture regain" is adopted, and the twist of the yarn is too large to ensure the tightness between the strands and increase the distance between fibers. Cohesion, improve yarn strength. The roving is subjected to humidity-conditioning treatment to adjust its moisture regain to the test conditions before spinning, so as to achieve the purpose of softening Fushun fiber and greatly reducing hairiness. In the selection of special accessories, the jaw adopts a 3.0mm spacer with a pressure bar, which forms a curved draft in the front draft area to increase the additional friction force and reduce the length of the floating area to strengthen the control of the floating fiber movement and improve Yarn evenness. The front rubber roller uses WRC970 soft elastic rubber roller, PG13854 plated steel ring, Swiss Blake C1 EL udr type 3/0 steel traveler, to control the air ring, reduce hairiness, and ensure excellent yarn evenness. The roller gauge is (15-20)×(15-25)mm. Process parameters such as yarn twist coefficient, roving moisture regain, contact tightness between ceramic working surface and sliver, and draft ratio in the rear area in soft and clean spinning all have different degrees of influence on the product quality of the finished yarn and the spinning effect. The configuration of the main process parameters is: the roller gauge is (15-20)×(15-25)mm, the dry weight of the yarn is 1.5-1.8g/100mm, the roller gauge is (15-20) (30-35)mm (V type drafting), drafting in the rear area is 1.01-1.04, and the speed of the front roller is 150-180r/min.

(7) Winding process measures

In order to maintain the superior performance of soft and clean dyed yarn with less hairiness, the "low speed, small tension" process measures are adopted in the winding to keep the winding channel clean, the yarn breaking device is flexible, and the air pressure setting is too small to control the bobbin after the end is broken. The friction with the grooved drum causes the yarn to be worn out, so as to reduce the growth of hairiness and reduce the generation of neps. Reasonably configure the electric cleaning process to reduce yarn defects, and at the same time pay attention to the quality of empty twist knots to ensure the quality of yarn. The specific process parameters are: neps + (380-400)%, short thick + (125-145)% (1.2-1.4) cm, long thick + (110-130)% (20-25) cm, details - ( 30-50)% (30-35) cm, winding speed 700-950m/min, spinning tension 9-11cN.

Advantage and beneficial effect of the present invention are:

(1) Solve the problem of reducing fiber use efficiency and increasing the cost of fabrics caused by more hairiness caused by short fibers such as cashmere and spun silk in spinning, improve yarn smoothness, and improve product anti-pilling and abrasion resistance .

(2) During the spinning process of soft and clean colored spun knitting yarn, the spinning process is optimized and quality management is strengthened to ensure smooth production and avoid quality problems such as color difference, uneven color mixing, color spots, neps, and unevenness. generation.

(3) The raw materials used in the present invention are all green and environmentally friendly fibers, and the finished fabric does not need to be finished by printing and dyeing. The product fully conforms to the current concept of healthy consumption that people advocate green and environmental protection.

The mixing mode selected in the present invention:

In the present invention, because there are many sericin and impurities on the surface of the spun silk, the difference in cutting length is large. In addition, after the oil-water antistatic agent is added, it is easy to entangle the rollers and rubber rollers after rapid moisture absorption, and the spinnability is poor, resulting in spinning pure silk. Silk strips are difficult. In order to improve its spinnability, the method of mixing spun silk with wood fiber cotton bales is used to make wood fiber/spun silk raw sliver, and then mixed with colored cotton raw sliver and cashmere raw sliver through sliver mixing, and then combined with ring spinning After the transformation of soft and clean spinning technology, it has unique spinning characteristics and optimized process design.

The spinning process flow selected in the present invention:

Dyeing cotton fiber: FA002 automatic plucking machine → FA022 multi-bin cotton blending machine → FA106 porcupine opener → FA046 vibrating cotton box feeder → FA141A single hand lapping machine → FA201B carding machine;

Dyeing wood fiber + spun silk → FA002 automatic plucking machine → ZFA026 automatic cotton blending machine → FA106A card needle opener → FA046A vibrating cotton box feeder → FA141A single hand lapping machine → FA201B carding machine;

Colored cotton raw sliver + wood fiber/silk colored raw sliver + cashmere dyed sliver → FA306 draw frame (three passes) → TJFA458A roving frame → DTM129 spinning frame (soft and clean spinning technology transformation) → NO.21C automatic winder.

The production process of each process of spinning in the present invention: (1) dyeing and pretreatment of fibers

Cotton and fiber dyed by external processing, to minimize the color difference of the fiber, the strength of the dyed fiber is reduced, and the fiber is hardened. In order to improve its spinnability and uniform mixing, the cotton feeding machine is used to pre-open the colored fiber After mixing with the wool machine, it is evenly wetted and 0.3% oil agent is added, and it is stuffed for 24 hours, so that the moisture regain of the colored cotton fiber reaches 8.7%. Wood fiber absorbs and dehumidifies quickly, and static electricity is easily generated during production. It is necessary to add 0.6% antistatic agent, and the moisture regain is controlled at 12%, so as to ensure that it is in a state of dehumidification during the entire spinning process.

In order to reduce the tendency of spun silk to generate static electricity during the spinning process and the phenomenon of winding machine parts, the formula of 0.6% antistatic agent, 0.2% water-soluble silicone oil, 0.5% flat plus, and 10% water is used to spray evenly and keep it moist for 24 hours. , so that the moisture regain is 12.3%, which improves its spinnability. The moisture regain of dyed cashmere fiber reaches 15.2%.

(2) Process measures for opening and cleaning cotton

The spun silk is thin and soft, with many silk and hair particles, and it is not easy to remove. The process principle of "grasping frequently and less grasping, combing more and beating less, mixing evenly, falling early, low speed, and anti-sticking" is adopted to properly enlarge the dust. The distance between the rods is 8 mm. Beater speed should be appropriately reduced, among them, the beater speed of ZFA026 automatic cotton blending machine is designed according to the minimum, the beater speed of FA106A card needle opener is 480r/min, the speed of FA046A vibrating cotton box feeder is 40m/min, the speed of corner nail cord is 40m/min, and the cotton equalizing roller and Corner nail curtain spacing is 10mm, FA141A single hand lapping machine card beater speed is 700r/min, lap roller speed is 12.3r/min; The wood fiber and spun silk are relatively fluffy, the basis weight of the cotton lap is 370g/m, and the length of the cotton lap is 27.4m. The relative humidity of the environment was controlled at 68%.

(3) Carding process measures

Spun silk fiber is soft, smooth and long, with low strength, easy to break and form short pile during carding process, and blended with dyed wood fiber, the poor cohesion between fibers and the generation of static electricity will cause floating ends, holes, and rotten edges in the cotton web In case of poor web formation, the carding adopts the process principle of "four fronts and one accuracy, low speed, large gauge, and high speed ratio", increases the tension of the cotton web and installs a guide apron device, on the basis of avoiding fiber damage Improve the carding effect, reduce rubbing back, realize fast and good fiber transfer, and improve the quality of cotton web and raw sliver. Cylinder card clothing AC2520×01850, doffer card clothing AD4030×01890, cover card clothing MCC36. Adjust the cylinder-cover gauge to 0.35mm, 0.33mm, 0.30mm, 0.30mm, 0.33mm, enlarge the feeder-licker-in roller gauge to 0.30mm, cylinder-doffer gauge to 0.20mm, cylinder speed 300rpm, licker-in speed 630rpm, raw sliver weight control at 20.6g/5m, raw sliver delivery speed 78m/min. The relative humidity of the environment is controlled at 65%-70%. Sliver quality control range: neps 34 grains/g.

(4) Drawing process measures

In order to improve the color mixing uniformity of color spinning and ensure the uniform mixing and accurate mixing ratio of various components, the drawing process adopts three steps. Because the cashmere in the melange yarn has a large degree of curl, good fiber elasticity, and good cohesion, the drawing process mainly focuses on improving the parallelism of the fibers and improving the evenness of the cooked sliver. The "light weight, slow speed, and large separation distance, heavy pressure" process principle. Properly reduce the speed of the vehicle, use soft elastic rubber rollers treated with composite coatings and increase the pressure to prevent winding roller rubber rollers. The drawing head and the second pass adopt parallel drafting, which is beneficial to the straightening of the fiber. The channel should be smooth and clean. Because the cashmere slivers are relatively fluffy, 6 slivers are combined, including 2 colored cotton raw slivers with a weight of 21.8g/5m, 3 colored raw slivers of wood fiber/silk silk, and 1 cashmere dyed sliver. The relative humidity of the environment is controlled. At 66%.

(5) Roving process measures

The roving process is mainly to further improve the parallel separation degree of fiber straightening, improve the evenness and control the elongation. The roving process adopts the process principle of "heavy pressure, low speed, light weight, small tension, and large twist". Large axial winding density reduces accidental tension and end breaks during unwinding of spun yarn. The twist coefficient of the roving is too large to control, and the smaller roving tension is used, which is conducive to the cohesion of fibers in the sliver, preventing the roving from being accidentally elongated and causing fine details, and is conducive to improving the drafting quality of the spun yarn. Give full play to the leading role of the main drafting zone, and use a small gauge when the draft can be opened, which is beneficial to control the floating fibers. Proper enlargement of the distance in the rear area can ensure that the fibers are fully straightened in the rear area and reduce fiber damage. Baker rubber rollers treated with antistatic agents are used.

(6) Soft and Clean Spinning Positioning Spinning Technology and Process Optimization of Soft and Clean Spinning Colored Yarn

Knitting yarn requires uniform dryness and less hairiness. The soft and clean spinning technology transformed from ring-spinning cotton spinning equipment is to apply a fiber smoothing treatment surface in the triangle area of ordinary ring-spinning spinning, and form a soft yarn in the yarn-forming triangle area. Many fiber holding points, these fiber holding points have a good holding effect on the exposed fiber head end, and cooperate with the twisting rotation force and the sliver traction force to effectively transfer the exposed fiber into the yarn body, reducing the yarn Thread surface hairiness improves finish. Through the action of heat and humidity, the fibers are softened, the bending stress of the fibers is greatly reduced, and the exposed long fibers are twisted, twisted and moved into the yarn body to eliminate or greatly reduce yarn hairiness. In the spinning process of soft and clean spinning, the technological principle of "low speed, small back draft, large twist coefficient, and large roving moisture regain" is adopted, and the twist of the yarn is too large to ensure the tightness between the strands and increase the distance between fibers. Cohesion, improve yarn strength. The roving is subjected to humidity-conditioning treatment to adjust its moisture regain to the test conditions before spinning, so as to achieve the purpose of softening Fushun fiber and greatly reducing hairiness. In the selection of special accessories, the jaw adopts a 3.0mm spacer with a pressure bar, which forms a curved draft in the front draft area to increase the additional friction force and reduce the length of the floating area to strengthen the control of the floating fiber movement and improve Yarn evenness. The front rubber roller uses WRC970 soft elastic rubber roller, PG13854 plated steel ring, Swiss Blake C1 EL udr type 3/0 steel traveler, to control the air ring, reduce hairiness, and ensure excellent yarn evenness. The roller gauge is 18×20mm. Process parameters such as yarn twist coefficient, roving moisture regain, contact tightness between ceramic working surface and sliver, and draft ratio in the rear area in soft and clean spinning all have different degrees of influence on the product quality of the finished yarn and the spinning effect. Yarn dry basis weight is 1.638g/100mm, roller gauge is 1832mm (V-type drafting), rear draft is 1.02, and front roller speed is 160r/min.

(7) Winding process measures

In order to maintain the superior performance of soft and clean dyed yarn with less hairiness, the "low speed, small tension" process measures are adopted in the winding to keep the winding channel clean, the yarn breaking device is flexible, and the air pressure setting is too small to control the bobbin after the end is broken. The friction with the grooved drum causes the yarn to be worn out, so as to reduce the growth of hairiness and reduce the generation of neps. Reasonably configure the electric cleaning process to reduce yarn defects, and at the same time pay attention to the quality of empty twist knots to ensure the quality of yarn. The specific process parameters are: neps + 390%, short thick + 135% 1.3cm, long thick + 120% 20cm, detail - 40% 30cm, winding speed 800m/min, spinning tension 10cN.

In summary, the above is only a preferred embodiment of the present invention, and is not intended to limit the implementation scope of the present invention.
