Embodiment 1

[0028] Pure cotton fabric, weave: plain weave; warp: 13tex, weft: 13tex, warp density: 515 threads / 10cm; weft thread density: 324 threads / 10cm. The diameter of the spray hole is 0.12mm. Injection pressure: 8Mpa; Injection distance: 5mm; Fabric conveying speed: 1.0m / min; Cycle times: 15 times.

[0029] Treatment effect: fabric air permeability from the original 500L / m 2 ·S drop to 315L / m 2 ·S. Fabric thickness increased from 0.3mm to 0.5mm. The treated fabric feels rich; the warp and weft strength of the fabric do not change significantly.

Embodiment 2

[0031] Polyester-cotton fabric (polyester / cotton: 65 / 35); weave: 2 / 1 twill; warp: 12.5tex, weft: 12.5tex, warp density: 525 / 10cm; weft density: 398 / 10cm. The diameter of the spray hole is 0.16mm. Injection pressure: 5Mpa; Injection distance: 12mm; Fabric conveying speed: 0.5m / min; Cycle times: 9 times.

[0032] Treatment effect: The air permeability of the fabric dropped from the original 560L / m2·S to 300L / m2·S. Fabric thickness increased from 0.26mm to 0.46mm. The treated fabric has a fluffy feeling; the warp and weft strength of the fabric have no obvious change.

Embodiment 3

[0034] Pure cotton fabric, weave: plain weave; warp: 20tex, weft: 20tex, warp density: 336 threads / 10cm; weft thread density: 336 threads / 10cm. The diameter of the spray hole is 0.20mm. Injection pressure: 4Mpa; Injection distance: 8mm; Fabric conveying speed: 0.4m / min; Cycle times: 8 times.

[0035] Treatment effect: The air permeability of the fabric dropped from the original 380L / m2·S to 116L / m2·S. Fabric thickness increased from 0.62mm to 0.9mm. The treated fabric feels rich; the warp and weft strength of the treated fabric has no obvious change.

Abstract

A method for finishing fabric by high-pressure water stream features that the high-pressure (2-8 MPa) water is sprayed onto the fabric conveyed at uniform speed (0.1-1.0 m / min). Its apparatus is composed of high-pressure water system consisting of high-pressure water source, pipeline, valves, water spraying tube and pressure meter, fabric conveying system, water circulating system and control system.

Description

technical field [0001] The invention relates to a fabric finishing method and equipment technology, specifically a method and equipment technology for finishing woven fabrics with high-pressure water flow, and the international patent classification number is proposed to be Int.c1 7 .D06B1 / 02. Background technique [0002] In order to make the fabric have a certain appearance, wearing comfort or required functionality, it is generally necessary to perform necessary processing on the gray fabric produced on the loom in production. This processing is called finishing. Traditional finishing methods include chemical and physical methods. Chemical finishing requires the use of corresponding chemicals or additives, and its production process often brings pollution to the environment. At the same time, the products sorted by this method also have potential dangers affecting human health and the possibility of continuing to pollute the environment during consumption or use.
