The use of irregularly shaped cross-section filaments and lyocell filaments gives the fabric a one-way moisture-wicking effect.

Description

Technical Field

[0001] This utility model relates to a linen-like polyester fabric, belonging to the technical field of polyester fabrics. Background Technology

[0002] Linen fabric is a type of fabric made from various bast fibers such as flax, ramie, jute, sisal, and abaca. It is generally used to make casual wear and work clothes. Finely spun linen fabrics, after special finishing processes, are used to make mid-to-high-end summer clothing and are very popular in the market. The advantages of linen fabric are its extremely high strength, excellent moisture absorption, heat conduction, and breathability. The disadvantages are that it is not very comfortable to wear, has a relatively rough and stiff appearance, wrinkles easily, and has poor drape. Moreover, due to the preference for natural fabrics, the supply and demand of bast fibers has become unbalanced, and prices have been rising continuously. Clothing made from natural linen fabrics has seen price increases due to cost pressures, significantly impacting sales. In this context, sales of imitation linen fabrics have increased. However, existing imitation linen fabrics are usually made by highly twisting polyester filaments and weaving yarns with different twist directions to create the linen-like effect. However, the use of polyester filaments makes this fabric insufficient in terms of moisture absorption and wicking. Utility Model Content

[0003] The purpose of this invention is to provide a linen-like polyester fabric that has a linen-like effect and a one-way moisture-wicking effect.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0005] The present invention relates to a linen-like polyester fabric, comprising a first fabric layer and a second fabric layer that are composite together.

[0006] The first fabric layer is woven from the first warp and the first weft in a crepe weave. The first warp and the first weft each include polyester filaments arranged in a 2:2 order with opposite twist directions and a first elastic yarn. The first elastic yarn includes PET / PBT composite elastic yarn and Lyocell filaments twisted together.

[0007] The second fabric layer is woven from the second warp and the second weft in a plain weave; both the second warp and the second weft include two filaments of wax filament arranged in a 2:2 order with opposite twist directions and a second elastic yarn, the second elastic yarn including PET / PBT composite elastic yarn and polyester / nylon blended yarn twisted together.

[0008] The polyester-nylon blended fiber includes parallel polyester DTY filaments and nylon 6POY filaments, with network dots arranged along the length direction. The cross-section of the monofilaments in the polyester DTY filaments and nylon 6POY filaments is cross-shaped or Y-shaped.

[0009] Based on the above scheme and as a preferred option: the polyester filament is dull polyester DTY filament with a twist of 24-30 twists per centimeter.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme: the cross-section of the monofilament in the matte polyester DTY filament is hollow.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme: the surface of the first fabric layer away from the second fabric layer has a nano antibacterial film layer formed by vacuum deposition technology, wherein the nano antibacterial film layer is nano zinc oxide or nano silver.

[0012] Based on the above scheme and as a preferred embodiment of the above scheme: the nano antibacterial film layer has a nano protective film layer on the side away from the first fabric layer 1; the nano protective film layer is titanium dioxide.

[0013] The beneficial effects of this utility model are as follows: The crepe weave used in the linen-like polyester fabric of this utility model gives the first fabric layer a linen-like effect. The alternating arrangement of elastic and non-elastic yarns enhances the crepe effect and strengthens the linen-like effect. Furthermore, the use of irregularly shaped cross-section filaments and Lyocell filaments gives the fabric a one-way moisture-wicking effect. Attached Figure Description
