Description

Technical Field

[0001] This utility model relates to the field of textile fabrics, and in particular to a channel fabric that conceals conductive wires. Background Technology

[0002] The demand for anti-static properties in down jacket fabrics increases during autumn and winter, especially in drier regions. Currently, the common method on the market is to add anti-static agents during the finishing process. However, this method is limited by the fabric's weight and durability; the finishing effect is not significant for lower weight fabrics, and the effect diminishes considerably after multiple washes. Some products use conductive fibers, which can solve the durability problem, but these fibers leave dark streaks on the fabric surface, severely affecting its appearance. Furthermore, non-laminated channel fabrics on the market do not incorporate conductive fibers to address static electricity.

[0003] Chinese Patent Publication No. CN111676566B discloses a down jacket channel fabric and its sewing method, comprising an upper fabric, a middle fabric, and a lower fabric. The upper, middle, and lower fabrics form common interlacing points at regular intervals. Between adjacent common interlacing points are M first channels and N (N≠M) second channels. The first channels are located between the upper and middle fabrics; the second channels are located between the middle and lower fabrics. The width of the first channels is greater than the width of the second channels to reduce the possibility of down leakage in the three-layer down jacket channel fabric. However, this down jacket channel fabric does not have embedded conductive fibers to solve static electricity, and therefore lacks antistatic properties.

[0004] Chinese Patent Publication No. CN112342669B discloses an electrostatic protective moisture-absorbing and heat-generating fabric and its molding process. The fabric comprises a textile yarn formed from acrylic fibers and viscose, and a composite yarn formed by further twisting acrylic fibers and conductive fibers together. The textile yarn is weft-knitted to form the fabric; wherein the composite yarn is arranged in a transverse stripe pattern within the fabric. By incorporating conductive fibers within the fabric and integrating them with conventional textile fibers as part of the fabric, a mesh-like circuit can be formed within the fabric to eliminate static electricity. However, the addition of conductive fibers leaves dark streaks on the fabric surface, affecting its aesthetics. Utility Model Content

[0005] Therefore, in order to address the above-mentioned problems, this utility model provides a channel fabric with concealed conductive fibers, which solves the problem that existing down jacket fabrics cannot simultaneously achieve antistatic function and aesthetics.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A channel fabric for concealing conductive threads includes a fabric body with a double-layer structure, comprising an upper channel fabric and a lower channel fabric. Conductive threads are disposed at the connection points of the two channel fabrics. The fabric body is woven from warp and weft yarns, with the warp yarns completely wrapping around the conductive threads to achieve complete concealment. The weft yarns include weft A and weft B. The warp yarns are arranged as first to eighth warp yarns, and the weft yarns are arranged by several repeating structures. Each repeating structure includes a first weft sequence unit, a second weft sequence unit, a third weft sequence unit, and a fourth weft sequence unit. In one repeating structure, the first and third weft sequence units are repeated once, and the second and fourth weft sequence units are repeated 215 times. In the first and third weft sequence units, the ratio of weft A to weft B is 1:1, while the second and fourth weft sequence units only use weft A.

[0008] Furthermore, the first latitude sequence unit includes latitude sequence 1, latitude sequence 2, latitude sequence 3 and latitude sequence 4 arranged in sequence; wherein, the pattern of latitude sequence 1 is 3 and 7, the pattern of latitude sequence 2 is 1, 3, 4, 5, 7 and 8, the pattern of latitude sequence 3 is 1 and 5, and the pattern of latitude sequence 4 is 1, 2, 3, 5, 6 and 7.

[0009] Furthermore, the second latitude sequence unit includes latitude sequence 5, latitude sequence 6, latitude sequence 7 and latitude sequence 8 arranged in sequence; wherein, the pattern of latitude sequence 5 is 3 and 7, the pattern of latitude sequence 6 is 1, 3, 4, 5, 7 and 8, the pattern of latitude sequence 7 is 1 and 5, and the pattern of latitude sequence 8 is 1, 2, 3, 5, 6 and 7.

[0010] Furthermore, the third latitude sequence unit includes latitude sequence 865, latitude sequence 866, latitude sequence 867 and latitude sequence 868 arranged in sequence; wherein, the pattern of latitude sequence 865 is 2 and 6, the pattern of latitude sequence 866 is 1, 2, 4, 5, 6 and 8, the pattern of latitude sequence 867 is 4 and 8, and the pattern of latitude sequence 868 is 2, 3, 4, 6, 7 and 8.

[0011] Furthermore, the fourth latitude sequence unit includes latitude sequence 869, latitude sequence 870, latitude sequence 871 and latitude sequence 872 arranged in sequence; wherein, the pattern of latitude sequence 869 is 2 and 6, the pattern of latitude sequence 870 is 1, 2, 4, 5, 6 and 8, the pattern of latitude sequence 871 is 4 and 8, and the pattern of latitude sequence 872 is 2, 3, 4, 6, 7 and 8.

[0012] The "pattern planting" refers to the instruction code used during the weaving process to control whether each warp yarn is lifted or not in order to form a specific pattern or structure.

[0013] The weft sequence 1 has weft threads 3 and 7, meaning that when this weft yarn is woven in, the 3rd and 7th warp yarns are raised.

[0014] The weft sequence 2 has the pattern 1, 3, 4, 5, 7, 8, which means that when this weft yarn is woven in, the 1st, 3rd, 4th, 5th, 7th, and 8th warp yarns are lifted.

[0015] The weft sequence 3 has the pattern 1 and 5, meaning that when this weft yarn is woven in, the 1st and 5th warp yarns are lifted.

[0016] The weft sequence 4 has the pattern 1, 2, 3, 5, 6, 7, which means that when this weft yarn is woven in, the 1st, 2nd, 3rd, 5th, 6th, and 7th warp yarns are lifted.

[0017] Furthermore, the warp yarn is made of 20D round-hole bright nylon yarn.

[0018] Furthermore, the weft yarn is made of 20D / 48F nylon FDY yarn and 20D spandex loose yarn twisted together.

[0019] Furthermore, the weft yarn is formed by twisting together 20D / 24F nylon DTYFDY yarn, 20D / 3F nylon conductive yarn, and 20D spandex loose yarn.

[0020] Furthermore, the conductive wire is a 20D / 3F nylon conductive wire.

[0021] The conductive wire is made of 20D / 3F nylon, whose carbon black component provides stable conductivity, quickly releases static electricity, and prevents dust adsorption. By embedding a specific proportion of conductive wires in the weft yarn cycle (only Mk2 yarn is used in the second and fourth weft units to control costs), the antistatic standard is achieved while optimizing the amount of conductive material used and reducing production costs.

[0022] By adopting the aforementioned technical solution, the beneficial effects of this utility model are as follows:

[0023] By employing a double-layer structure and a design where the warp yarns completely enclose the conductive fibers, the conductive fibers are fully concealed, achieving an appearance where they are invisible on both sides of the fabric. This concealment design not only enhances the fabric's aesthetics and avoids visual interference that could result from exposed conductive fibers, but also prevents wear or oxidation problems caused by exposed fibers. Simultaneously, it meets national standards for antistatic performance, improving the down jacket's ability to prevent down leakage and its antistatic properties. The specific ratio of warp, weft, and yew yarns ensures the conductive fibers remain in their fixed positions within the fabric, enhancing structural durability. The unique weft yarn arrangement design gives the fabric a special texture and structure, contributing to improved strength and stability. Attached Figure Description
