Description

Technical Field

[0001] This invention relates to a highly durable double-sided fabric that suppresses protrusion by using hollow fibers as connecting threads. Background Technology

[0002] Generally speaking, knitted fabrics are divided into plain weave (or plain knit, Single Jersey) and double-sided weave (or double-sided knit, Links and Links).

[0003] It is knitted using only one of the two needle beds, front and back, and is the most basic structure in knitting. It is soft and lightweight.

[0004] In addition, the flat structure makes it easy to distinguish the front and back, has less elasticity, and is mainly used as a material for T-shirts, sweaters, underwear, etc., and has lateral elasticity.

[0005] The disadvantage of these plain knit or single-knit fabrics without ribs is that the edges tend to curl.

[0006] On the other hand, the double-sided weave is formed by the intersection of the plain and reverse knits. Therefore, double-sided fabric refers to fabric with 100% identical weave on both sides, and is widely used in jackets, newborn supplies, children's clothing, as well as underwear, T-shirts, dresses, and various other garments.

[0007] However, double-sided fabric has the problem of the connecting lines on both sides protruding outwards.

[0120] Because the padding fabric of this embodiment can provide elasticity in all directions—up and down, left and right, and front and back—it has the characteristic of providing strong compression force to the user.

[0121] The connector 500 connects the single-sided fabric 1 to the other-sided fabric 2.

[0122] The connector 500 is characterized by using hollow fibers. In this embodiment, hollow wires are used as the connector 500.

[0123] The connector 500 is made of hollow fiber, which improves the span performance and solves the problem of exposed neoprene fabric.

[0124] The raw material for the hollow fiber is semi-double polyester chips (T200N manufactured by Toray Fiber (Nantong) Co., Ltd.). The polyester chips are dried using a pre-crystallization dehumidification dryer to achieve a moisture content of 39ppm after drying.

[0125] The dried chips are melted, extruded by a screw, and transported through a pipeline to a metering pump. The polymer, accurately metered by the metering pump, is then delivered to the spinneret.

[0126] The heat dissipation port of the heat dissipation pack is a hollow waterproof port with a cooling distance of 65mm and a side blowing speed of 35m / min. The hollow polyester fiber is obtained by DSD high-speed spinning process.

[0127] For example, the characteristics of the hollow fiber are as follows: fiber type 100T-10f, triangular hollow cross-section, 30.0% hollowness, monofilament. The mesh fineness is 10.0 dtex, the radius of curvature before heat treatment is 40.0 mm, and the radius of curvature after dry heat treatment at 160℃ for 3 minutes is 7.8 mm. This fiber is selected as the raw material for both the sheath fiber and the core fiber, with a sheath filament supply rate / core filament supply rate ratio of 20 times excess. The loose tow is processed into loose filaments, with six filaments combined into one to obtain a loosened tow with a bulkiness of 650 inch³ / 30g.

[0128] The hollow fiber has a cross-sectional hollowness ratio in the range of 30.0% to 45.0%, and has a three-dimensional compressed shape in its natural state. The compressed shape is a hollow polyester filament with a curvature radius in the range of 10.0 mm to 50.0 mm.

[0129] The hollow fibers are monofilaments in the range of 5.0 dtex to 10.0 dtex. After island formation, they are subjected to dry heat treatment at 160°C for 3 minutes, and their radius of curvature is in the range of 3.5 mm to 10.0 mm.

[0130] The hollow fiber is made of polyester, polyethylene terephthalate, polyethylene terephthalate, or polybutene, which may be selected from terephthalate esters or their modified polymers.

[0131] The dried chips are melt-extruded by a screw and transported through a pipeline to a metering pump. The metering pump delivers accurately metered polymer to the spinneret, which is a hollow spinneret with a cooling distance in the range of 10 to 150 mm and a side-blowing speed in the range of 25 to 90 m / min.

[0132] The hollow structure has a hollow ratio of 27% to 35% relative to the cross-sectional area.

[0133] The cross-section of the hollow space formed inside the hollow structure can be any one of a circle, a triangle, or a square.

[0164] The multiple warp yarns 640 are spaced apart at predetermined intervals in the left-right direction, and the multiple weft yarns 650 are also spaced apart at predetermined intervals in the up-down direction.

[0165] A gap is formed between the connecting yarns, and the connecting yarn 500 passes through the warp yarns 640 and weft yarns 650, which are set at regular intervals.

[0166] In this embodiment, the warp yarn 650 is formed with a thickness of about 20 to 70 denier, and the warp yarn 640 is formed with a thickness of about 70 to 350 denier, so that the connecting yarn gap can be formed into a rectangular shape.

[0167] The intermediate fabric 600 further includes: a first gap 610, formed at intervals in the left-right direction, for the first connecting yarn 510 to pass through; a second gap 620, formed at intervals in the left-right direction, for the second connecting yarn 520 to pass through; and a third gap 630, formed at intervals in the left-right direction, for the third connecting yarn 530 to pass through.

[0168] The first first connecting part 511, the third first connecting part 513, the fifth first connecting part 515 and the seventh first connecting part 517 penetrate the first gap 610 in the vertical direction.

[0169] The first and second connecting parts 521, the third and second connecting parts 523, and the fifth and second connecting parts 525 penetrate the second gap 620 in a vertical direction.

[0170] The first and third connecting parts 531, the third connecting part 533, the fifth connecting part 535, and the seventh connecting part 537 penetrate the third gap 630 in the vertical direction.

[0171] In this embodiment, three inclined surfaces are provided between the first gap 610, the second gap 620, and the third gap 630. In this embodiment, five weft threads are placed between the first gap 610 and the second gap 620, and five weft threads are placed between the second gap 620 and the third gap 630.

[0172] The intermediate fabric 600 can be a functional material.

[0173] The intermediate fabric 600 may be at least one of polyester fiber, spandex, Lycra, polyurethane, Coolmax, and Gore-Tex.

[0174] When the connecting line 500 is pulled in the loop portion woven into the single-sided fabric 1 or the other-sided fabric 2, a groove can be formed in the single-sided fabric 1 or the other-sided fabric 2.

[0175] Since the intermediate fabric 600 supports the single-sided fabric 1 or the other-sided fabric 2, the connecting yarn 500 can suppress the woven loop portion from being pulled, thereby having the feature of suppressing the formation of grooves in the single-sided fabric 1 or the other-sided fabric 2.

[0176] The double-sided fabric according to this embodiment also includes a support member 700 that is bonded and fixed to the intermediate fabric 600. Viewed from above, the support member 700 is annular and has a support hole 705 that penetrates through the center of its interior.

[0177] The first gap 610, the second gap 620 and the third gap 630 are connected within the support hole 705.

[0178] The upper support is bonded and fixed to the upper surface of the intermediate fabric 600. The lower support is bonded and fixed to the lower surface of the intermediate fabric 600. It includes a lower support.

[0179] The first first connecting part 511, the third first connecting part 513, the fifth first connecting part 515 and the seventh first connecting part 517 may be configured to pass through the support hole 705.

[0180] The upper and lower support members are bonded and fixed to the middle fabric 600 to support the first gap 610, the second gap 620 and the third gap 630, and to prevent damage caused by the connecting line 500.

[0181] During the weaving process of the connecting wire 500, if the connecting wire 500 does not pass through the first gap 610, the second gap 620 and the third gap 630 accurately, the connecting wire 500 will pass through the support member 700.

[0182] At this point, even if the connector 500 penetrates the support 700, it can prevent the intermediate fabric 600 from being cut or damaged and from becoming loose.

[0183] In other words, the support member 700 has the property of suppressing manufacturing defects, because even if the connecting yarn 500 breaks during the weaving process, the support member 700 can fix the fibers of the intermediate fabric 600.

[0184] In this embodiment, the diameter of the support member 700 is formed to be at least greater than the diameter of three warp yarns 640 or three weft yarns 650, and preferably, it is adhesively fixed to the warp yarns 640 and weft yarns 650.

[0185] The remaining configurations are similar to those in the first embodiment, so detailed descriptions are omitted.

[0186] Although specific embodiments have been described in the detailed description of the invention, various modifications can certainly be made without departing from the scope of the invention. Therefore, the scope of the invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by their equivalents.
