Description

Technical Field

[0001] The present invention relates to the technical field of textiles, and in particular to a composite molding method for textiles. Background Art

[0002] Filled textiles refer to textiles filled with down, polyester fiber, etc. These fillers can improve the touch of textiles and enhance their thermal insulation properties. Filled textiles include down quilts and fiber quilt cores.

[0003] Down quilts are filled with down (such as duck and goose down) or imitation down (such as polyester, a special fiber that mimics the fluffiness and warmth of natural down). Down quilts offer excellent warmth retention, are light and soft, have excellent breathability and moisture-wicking properties, and are durable.

[0004] A fiber quilt core is a core product that uses fiber (such as cotton fiber, polyester fiber, polyacrylonitrile fiber, wool, etc.) as the main filling material. Fiber quilt cores have the advantages of being inexpensive, having good warmth retention, and being easy to clean.

[0005] The production process of filling textiles in the related art suffers from the following drawbacks: cumbersome operations and poor composite stability. For example, in the production of down quilts, vertical lining strips are typically sewn between the outer and lining fabrics. This production method requires sewing, which is not only inefficient but also prone to thread loosening during the sewing process, affecting product quality. Furthermore, the sewing process requires precise positioning of each fabric layer, increasing operational difficulty and time costs. Over time, problems such as thread loosening and vertical lining strip shifting can occur. The composite quality is also unstable (due to needle and thread breakage) and has low breaking strength. For example, the production of fiber quilt cores typically involves positioning the outer fabric, wadding, and lining fabric before quilting. This process requires multiple pre-positioning and sewing of three or more layers of material (the outer and lining fabrics may also include lining fabric) on a quilting machine, which is cumbersome and inefficient. Furthermore, thread loosening can also occur during the quilting process, affecting product quality and user experience. In addition, traditional production processes rely heavily on manual operations and have a low degree of automation, making it difficult to meet the needs of large-scale industrial production. This is especially true when processing multi-layer composite structures (such as quilted quilt cores containing filling flakes). The process is complicated, the composite quality is unstable (caused by needle and thread breakage), and the breaking strength is low. Summary of the Invention

[0006] The present invention provides a composite molding method for textiles to solve the above-mentioned problems of low efficiency, easy generation of thread ends during the sewing process, affecting product quality, and the need to accurately position each layer of fabric during the sewing process, which increases the difficulty of operation and time cost. In addition, long-term use may cause problems such as thread ends falling off and vertical lining strip displacement, and poor composite quality stability (caused by needle and thread breakage) and low breaking strength. Thread ends may also be generated during the quilting process, affecting product quality and user experience. Traditional production processes rely heavily on manual operations and have a low degree of automation, making it difficult to meet the needs of large-scale industrial production. In particular, when processing multi-layer composite structures (such as quilted quilt cores containing filling flakes), the process is complicated, and the composite quality stability is poor (caused by needle and thread breakage) and low breaking strength.

Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments. The details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. The following embodiments and features therein may be combined with one another without conflict.

[0032] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. The drawings only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0033] One embodiment of the present invention provides a composite molding method for a textile, wherein the textile is a shell or quilt core for a down quilt. If the textile is a shell for a down quilt, the textile includes a face fabric 11, a lining fabric 13, and a flake 12 or a plurality of vertical lining strips 14 located between the face fabric 11 and the lining fabric 13. All vertical lining strips 14 are arranged in parallel and at intervals along the thickness direction of the textile, and the interior of the textile is divided into a plurality of filling units by the vertical lining strips 14. The composite molding method includes the following steps: placing all vertical lining strips 14 in parallel and at intervals between the face fabric 11 and the lining fabric 13, and then composite molding the textile by an integrated stamping method to produce the textile; If the textile is used for a quilt core, the textile includes a face cloth 11, a lining cloth 13, and a flake 12 located between the face cloth 11 and the lining cloth 13, that is, the textile includes the face cloth 11, the flake 12, and the lining cloth 13 arranged in sequence along the thickness direction. The composite molding method includes the following steps: stacking the face cloth 11, the flake 12, and the lining cloth 13 in sequence, and then composite molding them by an integrated stamping method to obtain the textile.

[0034] In the present application, the composite molding of multi-layer materials is achieved through an integrated stamping method, which avoids the low efficiency caused by multiple sewing processes in the existing technology, the easy generation of thread ends, and the need for precise positioning of each layer of fabric, which increases the difficulty of operation and time cost. In addition, long-term use may cause problems such as thread ends falling off and vertical lining strips shifting. The degree of automation is low, the composite quality stability is poor, and the breaking strength is low. Therefore, the composite quality stability and the degree of automation are improved.

[0035] During the integral stamping process, the cavities between adjacent vertical lining strips form filling units.

[0036] If the textile is a shell for a duvet, the integral punching pressure is 2-4 MPa, preferably 2.5-4 MPa.

[0037] In this application, if the textile is a shell for a down quilt, if the pressure of the integrated stamping is less than 2MPa, it is easy to cause insufficient interlayer adhesion, poor composite quality stability, low breaking strength, and easy breakage at the edge; if the pressure of the integrated stamping is greater than 4MPa, it is easy to damage the fibers, reduce the mechanical strength of the finished product, poor composite quality stability, and low breaking strength.

[0038] If the textile is a shell for a duvet, the temperature for integral stamping is 160-180°C, preferably 165-180°C.

[0039] In this application, if the textile is a shell for a down quilt, if the temperature of the integrated stamping is lower than 160°C, the viscosity of the adhesive increases, making it difficult to fully penetrate the fiber gaps, easily forming unwetted areas, reducing the interlayer bonding strength, resulting in poor composite quality stability and low breaking strength; if the temperature of the integrated stamping is higher than 180°C, it is easy to damage the fibers, accelerate the aging of the adhesive, reduce the interlayer bonding strength, resulting in poor composite effect and low breaking strength.

[0040] If the textile is a shell for a duvet, the duration of the integral punching is 25-35 seconds, preferably 28-35 seconds.

[0041] In this application, if the textile is a shell for a duvet, if the integral stamping time is less than 25 seconds, the cross-linking reaction of the adhesive is not fully completed, resulting in low interlayer bond strength and low breaking strength. If the integral stamping time is longer than 35 seconds, the cross-linking reaction of the adhesive is likely to be excessive, increasing the brittleness of the fabric, reducing its flexibility and impact resistance, resulting in poor composite effect, low breaking strength, and easy breakage of the fiber molecular chains, resulting in strength attenuation. The fabric is easily damaged.

[0042] If the textile is a shell for a duvet, the adhesive used during composite molding is a polyurethane adhesive.

[0043] In this application, the amount of polyurethane adhesive in the adhesive area is 0.5-1.0 g / cm 2 , preferably 0.6-1.0g / cm 2 .

[0044] In this application, if the amount of polyurethane adhesive in the adhesive area is less than 0.5g / cm 2 If the amount of polyurethane adhesive in the adhesive area is greater than 1.0g / cm 2 If the amount of adhesive is too high, the cross-linking density may be too high, resulting in a decrease in the flexibility of the finished product and a decrease in the breaking strength.

[0045] If the textile is a quilt core, the integral punching pressure is 1-3 MPa, preferably 1.5-3 MPa.

[0046] In this application, if the textile is a quilt core, if the pressure of the integrated stamping is less than 1MPa, it is easy to cause insufficient interlayer adhesion, poor composite quality stability, and low breaking strength; if the pressure of the integrated stamping is greater than 3MPa, it is easy to damage the fibers, reduce the mechanical strength of the finished product, poor composite quality stability, low breaking strength, and easily destroy the fluffy structure.

[0047] If the textile is a quilt core, the temperature of the integral punching is 180-200°C, preferably 185-200°C.

[0048] In this application, if the textile is a shell for a down quilt, if the temperature of the integrated stamping is lower than 180°C, the viscosity of the adhesive increases, making it difficult to fully penetrate the fiber gaps, easily forming unwetted areas, reducing the interlayer bonding strength, resulting in poor composite quality stability and low breaking strength; if the temperature of the integrated stamping is higher than 200°C, it is easy to damage the fibers, accelerate the aging of the adhesive, reduce the interlayer bonding strength, resulting in poor composite effect, low breaking strength, and the adhesive is easy to decompose, causing the fabric to easily turn yellow.

[0049] If the textile is a quilt core, the duration of the integrated punching is 15-20 seconds, preferably 16-20 seconds.

[0050] In this application, if the textile is a quilt core, if the time of the integrated stamping is less than 15s, the cross-linking reaction of the adhesive is not fully completed, the interlayer bonding strength is low, and the breaking strength is low; if the time of the integrated stamping is greater than 20s, it is easy to cause excessive cross-linking reaction of the adhesive, increase the brittleness of the fabric, reduce flexibility and impact resistance, poor composite effect, low breaking strength, and the fiber molecular chain is easy to break, the strength is attenuated, and the flakes are prone to shrinkage.

[0051] If the textile is a quilt core, the adhesive used during composite molding is polyamide adhesive.

[0052] In this application, the amount of polyamide adhesive in the adhesive area is 0.3-0.8 g / cm 2 , preferably 0.4-0.8g / cm 2 .

[0053] In this application, if the amount of polyamide adhesive in the adhesive area is less than 0.3 g / cm 2 If the amount of polyamide adhesive in the adhesive area is greater than 0.8g / cm 2 If the amount of adhesive is too high, the cross-linking density may be too high, resulting in a decrease in the flexibility of the finished product and a decrease in the breaking strength.

[0054] In this application, the material of the surface fabric is polyester fiber fabric, cotton fiber fabric, polyester fiber blended fabric, cotton fiber blended fabric or Tencel blended fabric.

[0055] In this application, the material of the lining is polyester fiber fabric, cotton fiber fabric, polyester fiber blended fabric, cotton fiber blended fabric or Tencel blended fabric.

[0056] In the present application, the material of the flakes is chemical fiber fabric, wool fiber fabric, silk fiber fabric or down.

[0057] In the present application, the material of the vertical lining strip is non-woven fabric or chemical fiber fabric.

[0058] In the present application, there is no limitation on the material of the non-woven fabric, and it may be, for example, polyester fiber, polypropylene fiber, polyurethane fiber, polyacrylonitrile fiber, polyamide fiber, cotton fiber, linen, etc.

[0059] In this application, chemical fibers include but are not limited to polyester fibers, polyacrylonitrile fibers, polypropylene fibers, and the like.

[0060] In the present application, the width of the vertical lining strip is 3-5 cm, preferably 3.5-5 cm.

[0061] In this application, the length of the vertical lining strip is the same as that of the face fabric.

[0062] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention.

[0069] Comparative Example 1 The difference between this comparative example and Example 1 is that the shell for the duvet is prepared by sewing, and the specific steps are as follows: One end of all 4 cm wide standing lining strips 14 (from the same source as in Example 1) is fixed to the lining fabric 13 (from the same source as in Example 1) with a specification of 60 cm * 60 cm by sewing. After the face fabric 11 (from the same source as in Example 1) and the lining fabric 13 are positioned, the other end of the standing lining strip 14 is fixed to the face fabric 11 by sewing. Then, the edges of the face fabric 11 and the lining fabric 13 are fixed by sewing, and a filling opening is reserved.

[0085] As shown in Table 1, the breaking strength of Example 1 is significantly improved compared to Comparative Example 1, and the breaking strength of Example 4 is significantly improved compared to Comparative Example 8. This result demonstrates that the present invention achieves composite molding of multiple layers of materials through integrated stamping, avoiding the low efficiency caused by multiple sewing passes in the prior art, which easily produces thread ends, requires precise positioning of each layer of fabric, increases operational difficulty and time cost, and may cause problems such as thread end shedding and vertical strip displacement in long-term use, resulting in a low degree of automation, poor composite quality stability, and low breaking strength, thereby improving composite quality stability.

[0086] As shown in Table 1, the breaking strength of Example 1 is significantly improved compared to Comparative Examples 2 and 3, and the breaking strength of Example 4 is significantly improved compared to Comparative Examples 9 and 10. These results demonstrate that, for different textiles, controlling the integral stamping pressure within a specific range can further improve the stability of composite quality.

[0087] As shown in Table 1, the breaking strength of Example 1 is significantly improved compared to Comparative Examples 4 and 5, and the breaking strength of Example 4 is significantly improved compared to Comparative Examples 11 and 12. These results demonstrate that, for different textiles, controlling the integral stamping temperature within a specific range can further improve the stability of composite quality.

[0088] As shown in Table 1, the breaking strength of Example 1 is significantly improved compared to Comparative Examples 6 and 7, and the breaking strength of Example 4 is significantly improved compared to Comparative Examples 13 and 14.
