Problems solved by technology

Because the yarn used in knitting and weaving cannot be too thick, and the monofilament used to reflect the transparent three-dimensional pattern will be relatively thin, and the strength of the thread is low, so if the transparent part of the pattern occupies the entire fabric surface When the proportion is relatively large or the proportion is relatively heavy, the bursting strength of the fabric may be greatly reduced, thereby affecting the wearing performance
And because the monofilament is a yarn formed by a single fiber, the designed fabric often has defects such as hard hand feeling and poor color fastness, and may also be accompanied by the problem of easy aging and not fastness to light washing

Embodiment 1

[0033] A hollow monofilament three-dimensional fabric, the preparation process of which is as follows:

[0034] (1) Select polyester-cotton blended CVS40 / 60, CVS45 / 55, CVS50 / 50, CVS55 / 45, CVS60 / 40 with yarn counts of 20S, 30S, 40S, 50S, 60S, 70S, 80S and yarn counts respectively Hollow polyester monofilaments of 20D, 30D, 40D, 50D, 60D, 70D, and 80D are woven into fabric gray fabric by single-sided circular weft jacquard loom.

[0035] The amount of polyester-cotton blended CVS is 80%, and the amount of hollow polyester monofilament is 20%.

[0036] Among them, 20S corresponds to 20D, 30S corresponds to 30D, and so on, a total of 35 kinds of gray fabrics are obtained.

[0037] The fabric gray cloth has a staple fiber yarn surface, and several hollow polyester monofilaments are alternately woven up and down on the staple fiber yarn surface. Alternate up and down weaving, that is, the polyester-cotton blended fabric forms the short-fiber yarn surface, and the hollow polyester ...

Embodiment 2

[0052] (1) The polyester-cotton blended CVS55 / 45 with a yarn count of 40S and the hollow polyester monofilament with a yarn count of 40D are woven into a fabric gray fabric by a single-sided circular weft jacquard machine.

[0053] The dosage of CVS55 / 45 is 80%, 85%, 90%, 95% respectively, and the dosage of hollow polyester monofilament is 20%, 15%, 10%, 5%.

[0054] The weaving steps are the same as in Example 1.

[0055] The 4 fabric gray cloths after resetting are tested, and the test results are as follows:

[0056] 1) Shrinkage rate: vertical 2.4% ~ 3%, horizontal 3.5% ~ 4%

[0057] 2) Color fastness to washing 4~5, color fastness to perspiration 4~5, color fastness to water 4~5, color fastness to dry rubbing 4, color fastness to wet rubbing 3, color fastness to sweat Fastness level 4

[0058] 3) Bursting strength 70PSI ~ 75PSI, anti-pilling grade 3 ~ 4

[0059] Among them, the greige cloth of the fabric with the dosage of 85% CVS55 / 45 and the dosage of hollow polyest...

Embodiment 3

[0061] (1) The polyester-cotton blended CVS55 / 45 with a yarn count of 40S and the hollow polyester monofilament with a yarn count of 40D are woven into a fabric gray fabric by a single-sided circular weft jacquard machine.

[0062] The amount of CVS55 / 45 is 85%, and the amount of hollow polyester monofilament is 15%.

[0063] (2) Pre-shape the gray cloth of the fabric, the pre-shaping temperature is 150°C, 160°C, 170°C, 180°C, 200°C, and the speed is 15m / min, 20m / min, 25m / min, 30m / min .

[0064] All the other steps are the same as in Example 1.

[0065] The 20 greige fabrics that were re-shaped were monitored, and the test results were as follows:

[0066] 1) Shrinkage rate: vertical 2.4% to 3.5%, horizontal 3.5% to 4.5%;

[0067] 2) Color fastness to washing 4~5, color fastness to perspiration 4~5, color fastness to water 4~5, color fastness to dry rubbing 4, color fastness to wet rubbing 3, color fastness to sweat Fastness level 4;

[0068] 3) Bursting strength 70PSI ~ ...

Abstract

The invention relates to a preparation method of hollow monofilament three-dimensional fabric. The method comprises the following steps: 1) weaving: selecting CVS blended yarns and hollow monofilaments to weave gray cloth of the fabric; (2) pre-shaping: pre-shaping the gray cloth of the fabric; (3) dyeing: dyeing the pre-shaped gray cloth of the fabric; (4) softening arrangement: performing softening arrangement on the dyed gray cloth of the fabric; (5) wrinkle-resisting arrangement: performing wrinkle-resisting arrangement on the gray cloth of the fabric which is subjected to the softening arrangement; (6) secondary shaping: performing secondary shaping on the gray cloth of the fabric which is subjected to the wrinkle-resisting arrangement in order to acquire the fabric, wherein the CVS blended yarns are CVS staple fibre yarns. The method enjoys the following advantages: hollow polyester monofilaments are selected such that the monofilaments can be adjusted on a jacquard machine; dueto the reasonable proportion of hollow polyester monofilaments and yarns, brusting of monofilament jacquard fabric is avoided; during a post-processing process, a heat-preserving thermal-insulating auxiliary agent is added in order to ensure that the fabric has a high heat-preserving thermal-insulating function.

Description

technical field [0001] The invention relates to the technical field of textile fabrics, in particular to a method for preparing hollow monofilament three-dimensional fabrics. Background technique [0002] At present, the special-shaped monofilament cross-sections seen on the market are circular, triangular, pentagonal, etc. Because the yarn used in knitting and weaving cannot be too thick, and the monofilament used to reflect the transparent three-dimensional pattern will be relatively thin, and the strength of the thread is low, so if the transparent part of the pattern occupies the entire fabric surface When the proportion is relatively large or the proportion is relatively heavy, the bursting strength of the fabric may be greatly reduced, thereby affecting the wearing performance. Moreover, because monofilament is a yarn formed from a single fiber, the designed fabric often has defects such as hard hand feeling and poor color fastness. [0003] Therefore, need badly a k...
