Three-dimensional spacer fabric

Abstract

This application discloses a three-dimensional spacer fabric, comprising two surface yarn fabric layers and a spacer yarn fabric layer. The spacer yarn fabric layer is formed by interlacing multiple first yarn bundles, with each first yarn bundle consisting of 2 to 6 first yarns. Each first yarn has a fineness of 3 to 30D. The spacer yarn fabric layer is woven with the two surface yarn fabric layers by interlacing multiple first yarns between them to form a three-dimensional structure. By subdividing the first yarn bundles, compared to a single fiber structure of the same fineness, the compressive stress of the spacer yarn fabric layer remains unchanged while the hand feel is softer. Therefore, by maintaining the original compressive stress, the performance of the three-dimensional spacer fabric is improved, resulting in a soft hand feel.

Description

Technical Field

[0001] This application relates to the field of fabric technology, and more particularly to three-dimensional spacer fabrics. Background Technology

[0002] With technological advancements, new textile technologies are constantly emerging, such as the three-dimensional integrated molding process of flat knitting technology. Three-dimensional fabrics are a new type of environmentally friendly woven three-dimensional material with a sponge-like three-dimensional structure. As three-dimensional textile technology continues to advance, it has evolved from traditional two-dimensional planar fabrics to three-dimensional fabrics, adding a longitudinal warp yarn system where yarn bundles are distributed and interwoven in three-dimensional space. Three-dimensional spacer fabrics, as a type of three-dimensional fabric, typically consist of two independent surface layers and an intermediate spacer layer, forming a unique sandwich structure.

[0003] The spacer layers of this type of three-dimensional spacer fabric are typically formed by interlacing multiple spacer filaments, each consisting of a single fiber. Generally, finer filaments result in a softer fabric feel and lower compressive stress, while thicker filaments produce a stiffer fabric feel and higher compressive stress. To ensure the three-dimensional spacer fabric maintains a predetermined compressive stress, the spacer filaments must have a predetermined thickness. Clearly, this type of three-dimensional spacer fabric cannot simultaneously achieve both; it cannot possess a soft hand feel while maintaining a predetermined compressive stress.

[0019] The following description is intended to disclose this application and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of this application defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of this application.

[0020] Those skilled in the art should understand that, in the disclosure of this application, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more roots," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple roots, and the term "a" should not be understood as a limitation on the number.

[0022] refer to Figures 1 to 2 A preferred embodiment of the three-dimensional spacer fabric according to this application will be described in detail below. The three-dimensional spacer fabric includes a spacer yarn fabric layer 10 and two surface yarn fabric layers 20. The spacer yarn fabric layer 10 is formed by interlacing multiple first yarn bundles 11, and each first yarn bundle 11 is formed by combining 2 to 6 first yarns 111. The thickness of each first yarn 111 is 3 to 30D. The spacer yarn fabric layer 10 is woven with the two surface yarn fabric layers 20 by means of multiple first yarns 111 passing through between the two surface yarn fabric layers 20 to form a three-dimensional structure.

[0023] In this way, by subdividing the first yarn bundle 11, compared with a single fiber structure of the same thickness, the compressive stress of the spacer yarn fabric layer 10 remains unchanged while the hand feel is softer. Thus, based on maintaining the original compressive stress, the performance of the three-dimensional spacer fabric is improved, making the three-dimensional spacer fabric soft to the touch.

[0024] Preferably, each of the first yarn bundles 11 is formed by combining at least three first yarns 111, so that the softness of the spacer fabric layer 10 woven from the first yarn bundles 11 is more obvious, thereby making the three-dimensional spacer fabric maintain its original compressive stress while being softer to the touch.

[0025] In one embodiment, the first yarn 111 is a single single fiber.

[0026] Preferably, the first yarn 111 is a monofilament FDY.

[0027] In another embodiment, the first yarn 111 is composed of multiple single fibers.

[0028] Preferably, the first yarn 111 is one or more fibers obtained by dissolving multifilament, mother yarn, DTY, fully drawn FDY, air textured yarn, disperse multifilament yarn, island yarn, orange segment yarn, drawn textured yarn, and water-soluble yarn.

[0029] refer to Figure 1 and Figure 3 Furthermore, the surface yarn fabric layer 20 is formed by interlacing multiple second yarn bundles 21, and the spacer yarn fabric layer 10 is placed between the two surface yarn fabric layers 20 in a manner in which multiple first yarn bundles 11 are woven with multiple second yarn bundles 21 of the two surface yarn fabric layers 20.

[0030] It is worth mentioning that each of the second yarn bundles 21 is formed by combining multiple second yarns 211, and the thickness of each second yarn 211 is 0.1~0.6D. In this way, based on the structural design of the first yarn bundle 11, by subdividing the second yarn bundles 21, the compressive stress of the first yarn bundle 21 remains unchanged while the hand feel is softer, further improving the performance of the three-dimensional spacer fabric, so that the three-dimensional spacer fabric maintains the original compressive stress while the hand feel is softer.

[0031] Preferably, each of the second yarn bundles 21 is formed by combining at least forty-eight second yarns 211, so that the surface yarn fabric layer 20 woven from the second yarn bundles 21 has a more pronounced softness, thereby making the three-dimensional spacer fabric feel softer.

[0032] In one embodiment, the second yarn 211 is a single single fiber.

[0033] Preferably, the second yarn 211 is a monofilament FDY.

[0034] In another embodiment, the second yarn 211 is composed of multiple single fibers.

[0035] Preferably, the second yarn 211 is one or more fibers obtained by dissolving multifilament, mother yarn, DTY, fully drawn FDY, air textured yarn, disperse multifilament yarn, island yarn, orange segment yarn, drawn textured yarn, and water-soluble yarn.

[0036] In this way, by adjusting the number of subdivisions of the first wire harness 11 and the second wire harness 21, the three-dimensional spaced fabric with different hand softness and maintaining a predetermined compressive stress can be produced as needed.

[0037] Preferably, the first yarn 111 and the second yarn 211 are made of one or more of the following materials: polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyethylene terephthalate, polybutylene terephthalate, petroleum separation and reaction-generated molecular materials, polyester fiber, polyamide fiber, acrylic fiber, vinylon, and polypropylene.

[0038] Preferably, both the first yarn 111 and the second yarn 211 are made of polyethylene terephthalate.

[0039] Preferably, the thickness of the three-dimensional spacer fabric is 1.3~20mm.

[0040] During production, the three-dimensional spacer fabric is set in a setting oven at a temperature range of 160~200℃ for 3~9 minutes.

[0041] Those skilled in the art should understand that the embodiments of this application described above and shown in the accompanying drawings are merely examples and do not limit the scope of this application. The advantages of this application have been fully and effectively implemented. The functional and structural principles of this application have been demonstrated and explained in the embodiments, and any variations or modifications can be made to the implementation of this application without departing from the stated principles.
