Description

Weaving method and yarn feeder

The invention relates to a weaving method of a horizontal knitting machine and a improvement of the yarn feeder and a function improvement, thereby improving the beauty of the surface of the woven fabric, and the main feature thereof is that the relatively loose yarn floats on the surface during the weaving process, and the relatively tight The yarn sinks inside, thus giving the woven fabric a more even aesthetic.

At present, knitted fabrics commonly used in the market, such as clothes, hats, scarves, etc., generally use a fully automatic horizontal knitting machine to achieve the purpose of mass production, but because of the horizontal back and forth weaving, the resulting yarn is elastic uneven, and the fabric has been Did not achieve a more perfect or more beautiful fabric.

As shown in the first figure, a schematic view of a knitted fabric of a single material woven by a horizontal knitting machine, which can be found by observing the surface of the cloth with a magnifying glass, the yarn is arranged with an obvious loose yarn (L) and tight yarn (T) interlaced. In the case, the reason is as follows: as shown in the second figure, the head (21) of the horizontal knitting machine (2) is in the working position, and when the transverse knitting displacement is gone, the feeding nozzle (22) is pulled. When the yarn is moved from the starting position to the other side, because the yarn is moved synchronously, the yarn of one of the left and right yarns is relatively tight (T) during the movement, and the returning is performed. When the machine head moves to the predetermined length position and wants to reverse the weaving and traversing, at this time, the other part of the yarn of the left and right yarns is only about one and a half of the aforementioned going distance, so the yarn is relatively loose. The yarn (L) is thus subjected to lateral displacement weaving until the desired cloth surface is completed, thereby producing a mixed pattern of loose yarn (L) and tight yarn (T).

In the case of a single-layer horizontal woven fabric, the woven fabric of the loose yarn is more beautiful in appearance, and the tight yarn is easy to pilling; in the same way, the above-mentioned loose yarn and tight yarn are arranged in the outer and outer layers of the knitted fabric. , affecting the level of the cloth.

The loose yarn and tight yarn produced by the knitting machine equipment on this kind of cloth material have been difficult to detect for a long time, but it cannot be avoided, and it does exist on all the horizontal knitting machine equipment, and there is no such thing as the strength of the knitted fabric. The impact, but for the overall beauty, touch and texture of knitted fabrics, there are great differences, especially in the era of industrial upgrading, not only the use of machinery and equipment for manufacturing, but also in the finished products of knitted fabrics. In itself, it also needs to be upgraded in order to achieve the upgrade of a comprehensive industry and promote the continuous progress of the industry.

Secondly, as shown in the third figure, the conventional yarn feeder (22) structure is disclosed, which mainly has a yarn feeding function, and the type of the yarn feeder (22) includes: a long-shaped receiving rod ( 221) The connecting body (222) is further fixed with a single hollow yarn feeding port (223), which can provide yarn threading; when installed in the above-mentioned horizontal knitting machine, it is fixed and fixed in running stroke form, although The effect of feeding the yarn, however, it is in the form of a single yarn feeder or a double yarn feeding, and the yarn is singulated, and the fabric of the knitted fabric is knitted by knitting the relatively loose yarn and the relatively tight yarn. There is no difference in the table. Because there is no relative loose yarn and tight yarn to distinguish the front and rear feeding yarns, the surface of the finished product has a smooth surface, beautiful appearance and texture.

Furthermore, as another conventional feeding nozzle (22) shown in the fourth figure, in addition to having a hollow yarn feeding port (223), a differently shaped yarn feeding port (224) is provided. The yarn feeding head is provided with two yarns of different materials or colors at the same time, and the woven fabrics can be knitted with different colors; however, due to the fixed form and the running stroke, there is still no change. Inconsistent yarn pattern on the surface of the fabric of the knitted fabric, that is, tight yarn, loose The yarn interlacing effect is neither smooth, beautiful and lacking in texture.

It can be seen that the improvement of people's living standards today, the requirements for fabrics are relatively improved, not only must be varied and comfortable, but also must be balanced, aesthetic and fabric touch and texture, therefore, how to solve the above situation, The focus of this case is to explore.

The present invention is directed to the above-mentioned deficiencies, and further provides an improved weaving method, which is particularly different from the yarn feeder feeding mode of a general horizontal knitting machine, but adopts a relatively front and rear type on a yarn feeding nozzle. The traverse feeding mode of the feeding yarn slot can make the relative loose yarn (L) in front and the tight yarn (T) in the transverse knitting when the yarn feeder is in the forward or return stroke. The yarn feeding method, in order to improve the consistency of the knit texture on the surface of the knitted fabric, has both flatness, beauty and texture, and is the main purpose of the creation.

Another object of the present invention is to provide a weaving method, which utilizes the front and rear yarn feeders of the left and right sets of yarn feeding nozzles to further match the high and low position settings, so that the front yarn feeding port is low and the rear yarn feeding is performed. The pattern of the mouth is fed to the yarn, and the effect of the positive and negative surface texture of the knitted fabric is achieved.

A further object of the present invention is to provide an innovative yarn feeder structure, which can maintain the yarn feeder at the front and the back during the knitting process of the knitting machine by means of a special yarn feeder structure. After the relatively high and low feeding type, the surface of the knitted fabric is smoothed and the yarn woven texture is consistent, and the durability and the appearance are taken into consideration.

In order to achieve the above objects, the improved knitting method of the present invention is mainly used on a horizontal knitting machine, and the knitting yarn is divided into left and right common yarns, and then drawn into the yarn feeder of the yarn guide, and the yarn feeder is fed. The yarn feeding slot is arranged in a front-to-back configuration, and the yarn feeding slot is in a front and rear position. The knitting running direction is based on; when the yarn feeder of the yarn feeder is running in the transverse direction, whether it is the forward or the return stroke, one of the yarn feeding slots is in front and the yarn for feeding the yarn is loose yarn (L), another feeding The yarn slot is behind and the yarn fed is a tight yarn (T).

In the above knitting method, the yarn feeding slot of the yarn feeder of the yarn guide is adopted in the front and rear setting modes, and the high and low design can be further matched to form a high and low difference type; accordingly, the yarn guide is made. When the yarn feeding nozzle is running in the lateral direction, regardless of the forward or return stroke, one of the yarn feeding slots is loose at the front yarn (L) and the yarn exiting position is relatively low, and the other yarn feeding slot is at the rear yarn. It is a tight yarn (T) and the yarn exit position is relatively high.

In addition, the yarn feeding nozzle designed by the invention can be directly used without changing the setting of the flat knitting machine. The structure of the yarn feeding nozzle comprises: a joint portion and a body integrally extending from one end of the joint portion. And a yarn guiding portion formed from one end of the body different joint portion; in particular, the yarn guiding portion has a pair of two arc-shaped and misaligned yarn feeding slots, and the outer edge of the yarn guiding portion Designed for the circular arc surface, the two yarn ends of the two yarn feeding slots are formed in a relatively low and rear high state.

The yarn guiding portion may further comprise two or more sets of arc-shaped notches that are opposite to the front, back, front and rear, high and low, and misaligned, to provide synchronous weaving operation of two or more different materials or color yarns.

Referring to the preferred embodiment shown in the fifth figure, the knitting method of the present invention is applied to, but not limited to, a horizontal knitting machine (1) having a yarn guiding track (11). a machine head (12) and left and right yarn guides (13) driven by the machine head (12) are provided on the yarn guiding track (11), and combined with microcomputer control and programmable programming, the machine is used. The head (12) traction guide (13) performs lateral weaving displacement, and the left and right yarn guides (13) respectively incorporate a yarn feeding nozzle (14), and the free end of the yarn feeding nozzle (14) has a yarn supply Feed the yarn feeder slot (15) (not shown).

Regarding the knitting method flow of the present invention, please refer to the schematic diagram of the horizontal knitting machine shown in the fifth figure; the main use of the horizontal knitting machine (1) is to divide the knitting yarn and then distribute the left and right common yarns to the relative yarn guides ( 13) feeding the yarn feeder (14), and causing the yarn feeding nozzles (14) of the left and right yarn guides (13) to form the yarn feeding notches (15) in a running direction to form a front front and a rear type. Setting (if the yarn guide runs from right to left, that is, the yarn feeding slot of the left feeding nozzle is front, and the feeding slot of the right feeding nozzle is backward, and conversely, if the yarn feeder runs from left to right When the feeding slot of the right feeding nozzle is the front and the feeding slot of the left feeding nozzle is the rear); thus, the relative loose yarn is automatically placed on the surface of the cloth during the knitting process. Relatively tightly placed into the inner layer of the fabric to weave the knitting The fabric structure of the yarn woven texture inside and outside the object.

In actual operation, through the above method, the yarn feeder (14) combined with the left and right yarn guides (13) can be operated in the transverse weaving operation (going, if the direction of the surface is from right to left), the guide The yarn feeding slot (15) of the yarn feeding nozzle (14) of the yarn feeder (13) is the front yarn and the yarn is loose yarn (L), the left yarn feeding slot (15) is behind and the yarn is tight yarn ( T); and the return stroke (the direction of the surface is from left to right) is just the opposite. At this time, the right yarn feeding slot (15) is in front and the yarn is loose (L) and the left yarn feeding slot (15) is After that, the yarn is a tight yarn (T).

In the above knitting method, the yarn feeding slot of the yarn feeder of the yarn guide is adopted in a front and rear setting mode, and can further be combined with the combination mode of high and low difference; thereby, in application, the yarn feeding The yarn feeding slot (15) of the nozzle (14) which is located at the front and has a low yarn output height can draw the yarn into a looser loose yarn (L), and the rear yarn has a higher yarn output height. The notch (15) pulls the yarn into a tight yarn (T), so that during the weaving process, the tight yarn (T) sinks and forms on the inner surface of the fabric, while the loose yarn (L) It will float up and be formed on the outside of the fabric; otherwise, when the yarn feeder (14) of the yarn guide (13) is running in the lateral direction (return), the yarn feeder (14) has a lower yarn feeder height. The mouth (15) is still kept in the front, and the yarn feeding slot (15) with a higher yarn height remains at the rear. According to the repeated weaving operation, the yarn weaving pattern of the front and back sides of the cloth can be formed. Consistency, achieving a smooth, beautiful and textured effect.

Based on the method theory of the present invention, a single yarn guide (13) can be directly used on the horizontal knitting machine (1) and matched with a special single yarn feeder (14), as shown in the sixth figure, instead of using The two sets of yarn guides and yarn feeders; as shown in the seventh figure, the yarn feeder (14) comprises: a joint portion (141) and a self-joining portion (141). a body (142) integrally extended at one end, and a yarn guiding portion (143) formed at one end of the different joint portion (141) of the body (142); in particular, the yarn guiding portion (143) has a set The two arcs are opposite and offset from the yarn feeding slot (15), and the bottom end of the outer edge of the yarn guiding portion (143) has a circular arc surface (16) design, so that the two yarn feeding slots (15) are two out The yarn ends form a relatively high and low profile.

Please refer to the sixth and seventh figures together, and the yarn feeder (14) design according to the above is sufficient for the horizontal knitting machine to replace the left and right yarn guides (13) in the foregoing method of the present invention. The yarn feeding slot of the yarn feeder must be in a front-to-back configuration; since the single yarn feeder (14) has two yarn feeding slots (15), and the single yarn opening is changed into a circular arc shape. Naturally, the front and rear position differences are formed, and the effect of the front and rear design of the yarn feeding slot (15) of the feeding yarn feeder (14) is the same as that of the above method; The end edge of the yarn slot (15) near the center of the yarn guiding portion (143) is designed by the arc surface (16) at the bottom end of the outer edge of the yarn guiding portion (143), so that the thickness of the bottom portion is thick, so the yarn is discharged. The position is lower, and the edge of the yarn feeding slot (15) far from the center of the yarn guiding portion (143) is designed by the arc surface (16) at the bottom end of the outer edge of the yarn guiding portion (143), resulting in the thickness of the bottom portion. The thinner, so the position of the yarn is higher, which is the same as the effect of forming the relatively high and low yarns of the yarn feeding slot (15) of the yarn feeding nozzle (14) by the yarn guide (13) in the above method.

Accordingly, in practice, the yarn feeder (14) of the present invention is mounted on a single yarn guide (13) of the horizontal knitting machine (1); when the yarn feeder (14) is run in the lateral direction (going, When the direction of the drawing is from right to left, one end of the yarn feeding slot (15) located at the center of the yarn guiding portion (143) and having a lower yarn opening can pull the yarn into a loose state of the yarn ( L), while at one end of the other yarn feeding slot (15) which is far from the center of the yarn guiding portion (143) and has a higher yarn exit opening, the yarn is made Pulling the tighter yarn (T), so that during the weaving process, the tight yarn (T) will sink and form on the inner surface of the fabric, while the loose yarn will float and be formed on the outside of the fabric; When the yarn feeder (14) is operated in the lateral direction (returning, from left to right in the direction of the drawing), the yarn at the end of the yarn feeding slot (15) which is originally lower in the yarn outlet is reversely moved to the yarn outlet. The higher end, and the yarn of the yarn feeding slot (15) which is higher in the original yarn exiting mouth is reversely moved to the lower end of the yarn discharging opening, and the same yarn is in the knitting process. (T) will sink and form on the inner surface of the fabric, and the loose yarn will float up and be formed on the outside of the fabric; thereby achieving a smoother and more beautiful appearance by forming the yarn weaving pattern on the inner and outer surfaces of the fabric. More textured effect.

As shown in the eighth figure, the yarn feeder (14) mentioned above is usually used for the weaving of a single yarn material or color, and in the case of the variable fabric of the knitted fabric, another different type of yarn feeder is required. (14), wherein: the yarn guiding portion (143) further comprises two or more sets of arc-shaped slots (15) with opposite arcs and offsets, so that two or more different types can be simultaneously provided. The yarn of material or color is subjected to synchronous weaving operation; as for the knitting principle and method, the same is true, and therefore will not be described again.

In summary, the weaving method and the yarn feeder of the present invention are a novel and progressive weaving method, which has great industrial value, especially the innovative yarn feeder, which can be used not only to be convenient but also to be more beautiful. And the high-quality knit fabric can achieve the intended purpose and effect. When the patent requirements have been met, the application for the invention patent is filed according to law; however, the above description is only one of the preferred embodiments of the present invention. However, equivalent structural changes in the scope of the present invention and the scope of the claims are intended to be included in the scope of the invention.
