Detailed Description

In order to make the objects, features and advantages of the present disclosure more comprehensible, the technical solutions in the embodiments of the present disclosure will be clearly described in conjunction with the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

As shown in fig. 1, an embodiment of the present disclosure provides a knitted fabric forming method based on 3D printing, the method including the steps of:

And S20, determining a connection area of the knitted fabric raw material and the 3D printing consumable. According to the application scene requirement of the product and the visual effect or functionality to be realized, the whole appearance and shape design is firstly carried out, and then, according to the design result, the connection area of the knitted fabric raw material and the 3D printing consumable can be determined. For example, the knitted fabric log includes one or more connection areas for connection with 3D printing consumables.

For example, when the knitted fabric material is used as a garment, 3D printing consumables can be added at specific positions of the garment, such as knee positions or elbow positions, and the connection positions of the specific positions and the 3D printing consumables are connection areas of the knitted fabric material. Or, for example, by combining 3D printing consumables with knitted fabric logs, a pattern such as a specific shape is achieved.

Step S30, knitting the knitted fabric raw material, and adjusting knitting characteristics of yarns in the connecting area. The knitting programming is performed according to a pre-design, and knitting is performed on the knitted fabric raw material by using a knitting machine, wherein during the knitting, the knitting characteristics of yarns in a connection area of the knitted fabric raw material need to be adjusted correspondingly. And correspondingly adjusting according to the actual application environment, scene and the like of the connection area. Thereby the raw material of the knitted fabric meets various use requirements. Knitting characteristics may be interpreted as yarn characteristics properties involved in knitting a knitted fabric stock, including but not limited to yarn material, yarn properties, knitting density, and the like.

For example, when the melting point of the yarn in the connection region is below a first set value, for example, below 220 degrees celsius, the yarn in the connection region is mixed with a high melting point material so that the melting point of the yarn in the connection region is above a first preset value.

For example, the yarns used in the knitted fabric raw material are made of materials with lower melting points, such as artificial fibers, and the melting points of the yarns in the connecting areas of the corresponding knitted fabric raw materials are also lower, so that the yarns in the connecting areas need to be at least increased in order to avoid damage to the yarns in the connecting areas by the 3D printing nozzle. For example, a high-melting-point fiber material such as natural fibers is added to the artificial fiber yarn and mixed with the original artificial fibers for knitting, thereby increasing the melting point of the yarn in the connection region. For example, the ratio of the natural fiber to the artificial fiber may be selected according to the amount of increase in the melting point.

For example, when the diameter of the yarn in the connection region is greater than the second preset value and/or the roughness is greater than the third preset value, the knitting density and/or the diameter of the yarn in the connection region is adjusted so that the diameter of the yarn in the connection region is smaller than the second preset value and/or the roughness is smaller than the third preset value. For example, when the yarns in the raw material/connecting area of the knitted fabric are thicker or coarser, at least the knitting density of the yarns in the connecting area is reduced, knitted into a relatively loose structure or replaced with finer and smoother yarns.

For example, when the 3D printing consumable is a set elastic material, the yarns in the connection area are mixed with the elastic material so that the elasticity of the yarns in the connection area is higher than a fourth preset value. For example, when the 3D printing consumable uses thermoplastic polyurethane elastomer rubber and the printed product is required to achieve a twisted 3D effect, spandex-containing elastic fiber or thread tissue with strong contractility can be used for knitting, so as to improve the plasticity of the knitted fabric raw material/connecting part. For example, the amount of elastic fiber mixed into spandex is determined based on the desired elasticity value.

For example, when the 3D printing supplies need to penetrate through the knitted fabric stock or have a set viscosity, the knitting density of the yarns in the connection area is adjusted. For example, when the 3D printing supplies need to have a good adhesion effect through the connection area, such as the product needs to meet the water washing requirement, or the product needs to be precisely matched in shape, the knitting density of the yarns in the connection area can be adjusted, that is, at least the knitting density in the connection area is reduced. Based on this, when carrying out 3D and printing, because the aperture of the mesh in the connection region is great, do benefit to the infiltration of 3D printing consumables, and then can improve permeability and bonding effect.

And S50, 3D printing is carried out through a 3D printer, and the connection area of the knitted fabric raw material is connected with 3D printing consumables. For example, the 3D printing by the 3D printer further comprises installing the knitted fabric raw material in a 3D printing initial state and/or installing the knitted fabric raw material in a 3D printing designated position, and finally, the combination between the 3D printing consumable and the designated position of the knitted fabric raw material is realized.

And step 60, carrying out deformation treatment on the connection area of the knitted fabric raw material subjected to 3D printing to obtain the formed knitted fabric. Through 3D printing operation, can realize the connection between 3D printing consumables and the knitting surface fabric raw materials, then, in step S60, carry out deformation processing again, obtain the product of further deformation.

For example, the connection area of the knitted fabric raw material is heated, wherein the heating source is a heating device such as a heat gun or an iron. For example, the knitted fabric raw material is the synthetic fiber with lower melting point, after the heating treatment, the synthetic fiber in the connecting area is contracted, and when the connecting area is contracted, the 3D printing consumable is driven by the contraction force to synchronously deform, so that the purpose of deformation treatment is further achieved.

For example, in the heating operation, it is necessary to uniformly and continuously heat the connection portion, and at the same time, care is also required to avoid the case of excessive local heat shrinkage or melting. The higher the temperature, the shorter the heating time. For example, about 3 minutes is required when heating at 350 degrees and about 5 minutes is required at 300 degrees, and in addition, the melting point of the artificial fiber can be adjusted accordingly.

For example, the connection region of the knitted fabric log is subjected to a water-soluble operation. The connecting area contains water-soluble yarns, the printed fabric is immersed in water, so that the water-soluble yarns in the connecting area are dissolved, the braiding structure of the part (the connecting area) is relaxed, and after no yarns are bound in the connecting area, the 3D printing consumable can be driven to deform synchronously, so that the purpose of deformation treatment is further achieved.

For example, the temperature of the water used is adjusted according to the specification of the water-soluble yarn, and when the water-soluble yarn is used, it is immersed in water having a temperature higher than 20 degrees, and when the conventional water-soluble yarn is used, it is immersed in water having a temperature higher than 40 degrees.

The water-soluble yarns are used for realizing the subsequent deformation effect, and when the knitting fabric raw material is subjected to knitting operation, the modes of incoming line, knitting and outgoing line are required to be set, namely the knitting of the water-soluble yarns in the connecting area is changed. So as to ensure that the rest parts are not damaged and shed after the water-soluble yarns are water-soluble.

For example, the portion that needs to be dissolved to form the knockover effect is determined, and the loop to be knocked over is transferred to the loop not to be knocked over before entering one or more rows of knitting of the portion, so that the portion to be knocked over is subsequently the loop to be knocked over in the next row of knitting. And carrying the water-soluble yarn into the last row before the knitting of the loop removing part is completed, knitting only the loops needing to be loop removed, and then changing back to the main yarn to continue knitting until all the fabrics are completed, so that the loop removing action starts from the knitting row of the velvet yarn without influencing the subsequent knitting part.

For example, the connection region of the knitted fabric log is subjected to a washing treatment. By combining the characteristics of the knitted fabric raw materials, yarns in the connection area after washing treatment deform, so that the 3D printing consumable can be driven to synchronously deform, and the purpose of deformation treatment is further achieved.

For example, the consumable material of the yarn in the connection region is a material containing natural animal fibers such as wool, and the shrinkage of the yarn is higher when the woven structure is looser and the natural animal fiber content in the yarn component is higher. When the felting is carried out, the shrinkage is affected by the water temperature for washing, the detergent, the rubbing and the spin-drying, and when a better shrinkage effect is required, warm water (30 ℃ and above), conventional washing (rubbing and spin-drying for more than 30 minutes) and the detergent (the dosage of the detergent is determined according to the knitted fabric quantity) are selected.

As shown in fig. 2, an embodiment of the present disclosure provides a knitting fabric forming method based on 3D printing, the method further including the steps of:

and S40, performing 3D modeling, acquiring a print file, and performing slicing processing according to the print file. After the production of the knitted fabric is completed, 3D modeling and slicing processing operations are required to complete subsequent 3D printing operations.

In some embodiments, the slicing of the print file includes determining the number of layers of fabric that need to be suspended and setting up a grid print path when the 3D printing consumable is not required to be connected to a printed portion and a tiled print path when the 3D printing consumable is required to be connected to a printed portion.

During 3D printing operation, the knitted panel raw material can be placed on the printing position first, or after 3D printing for a period of time, the knitted panel raw material is placed on the printed 3D printing consumable. When the 3D printing consumables are continuously connected with the printed 3D printing consumables, the 3D printing consumables are set to be a grid type printing path, namely, the 3D printing consumables have no permeation requirement during printing, when the printing is continuously performed, 3D printing of a grid type can be adopted, the connection strength is further reduced, and the connection part is easy to separate, otherwise, when the 3D printing consumables are required to be connected with the printed 3D printing consumables, the 3D printing consumables are set to be a tiled type printing path, namely, when the printing is continuously performed, the 3D printing consumables need to permeate the connection area, and the connection strength between the 3D printing consumables can be improved.

In the embodiment of the present disclosure, the product molding in step S60 may also be achieved by shrinkage deformation. For example, the shape, arrangement composition, thickness, etc. of the model need to be adjusted according to the topology principle and the fabric stretchability. The degree of deformation of the 3D printing part is related to the elasticity of the knitted fabric and the model printing thickness, wherein the deformation effect is more obvious when the elasticity of the knitted fabric is stronger, and the deformation effect is more obvious when the model printing thickness is thinner. When the combined shape is used for forming the deformation effect, the graph is designed to be in a form that the periphery is gathered towards the center, and a gap of 0.5cm to 1cm is reserved between graph units, so that the knitted fabric is contracted.

For example, before the knitted fabric raw material is connected with the 3D printing consumable material, pre-stretching treatment is performed, that is, the knitted fabric is outwards unfolded relative to a natural state, the 3D printing consumable material is connected to the unfolded knitted fabric, after 3D printing is completed, the knitted fabric is loosened, the knitted fabric is retracted to the natural state, and the 3D printing part is deformed while the knitted fabric is contracted.

As shown in fig. 3, an embodiment of the present disclosure provides a knitting fabric forming method based on 3D printing, the method further including the steps of:

And S10, acquiring parameter information of yarns used for the knitted fabric raw material, wherein the parameter information comprises one or more of yarn materials, melting points, outer diameters, roughness or knitting density.

When the knitted fabric raw material is produced, the knitting characteristics in the connecting area need to be adjusted so as to meet the use requirements of different 3D printing scenes. Therefore, the parameter information of the yarns in the determined knitted fabric is obtained in advance, so that the knitting characteristics of the yarns in the connecting area can be conveniently adjusted.

As shown in fig. 4, an embodiment of the present disclosure provides a knitting fabric forming method based on 3D printing, the method further including the steps of:

and S21, weaving the sample, testing parameter information of the sample, and determining that weaving is finished or performing adjustment on weaving according to a test result.

That is, before the production of the knitted fabric, in order to avoid the occurrence of knitting errors, the knitted fabric can be timely adjusted. For example, the test of the knitting sample comprises one or more of yarn material, melting point, outer diameter, roughness or knitting density, or can also test whether the knitting fabric visual effect, knitting structure is feasible, whole hand feeling and thickness, etc., and measure and calculate the length-width ratio of the loop (namely, n needle=n cm, n row=n cm), calculate the loop number and needle adding and subtracting actions of the knitting fabric according to the proportion data, adjust the final knitting programming file and complete knitting.

As shown in fig. 5, an embodiment of the present disclosure provides a knitting fabric forming method based on 3D printing, the method further including the steps of:

step S51, performing 3D printing through a 3D printer further comprises fixedly mounting the knitted fabric through a fixing device so as to avoid printing displacement of the knitted fabric.

When 3D printing is performed, the product printed by the 3D printing consumable is always static, so that the knitted fabric is required to be fixed correspondingly, and the knitted fabric is required to be fixed to be incapable of sliding. The knitted fabric is fixed, for example, by using an auxiliary fixing device, for example, a clip, by which the knitted fabric is fixed to a mounting plate of the 3D printer.
