Anti-streaky warp screening method of real silk fabric and application

Abstract

The invention discloses an anti-streaky warp screening method of a real silk fabric and application, and belongs to the technical field of real silk dyeing. The screening method comprises the following steps of 1) silk sampling, 2) silk dyeing, 3) silk colorimetry, 4) fabric sampling, 5) fabric dyeing and 6) fabric colorimetry. The step 2 of silk dyeing is performed under an acidic condition by adopting a neutral dye; and the step 5) of fabric dyeing is performed under an acidic condition by adopting a neutral dye or an acid dye. The screening method can effectively solve the problem of streaky warps during dyeing of the real silk fabric, and is applied to screening of the real silk fabric suitable for sensitive color dyeing. The screening method as a screening process is applied to the field of sensitive color dyeing of the real silk fabric.

Description

technical field [0001] The invention discloses a silk fabric anti-warp willow screening method and application thereof, belonging to the technical field of silk dyeing. Background technique [0002] Silk fabric refers to the fabric woven with real silk as yarn. In actual production, real silk is usually used as warp yarn, and weft yarn is woven with real silk yarn or other fiber yarns. Silk fabrics include all silk fabrics and silk interwoven fabrics. Both the warp and weft yarns are made of silk yarns, commonly known as all-silk fabrics; while the warp yarns are silk yarns, and the weft yarns are natural or regenerated cellulose fiber yarns, which are called silk interwoven fabrics. Common silk interwoven fabrics are made of silk warp yarns and weft yarns spun from at least one fiber of cotton, linen, viscose, and modal. [0003] The applicant found in the research that the following problems exist in the current dyeing process of real silk fabrics: [0004] First, the w...

AI Technical Summary

Problems solved by technology

However, the problem of warp willow is difficult to repair twice. Once it occurs, warp willow will often run through the whole piece of fabric, and the whole piece (50±5 meters) can only be treated at a lower level, and the economic loss is relatively high.

[0007] Second, the willow problem is particularly prominent when dyed with sensitive skin

Due to the large molecular weight of acid and neutral dyes, the chemical affinity with silk fibers is weak, resulting in poor dyeing hiding power, and it is easy to appear when dyeing some sensitive colors such as brown, gray, army green and brown. willow blemish

When silk is dyed with sensitive colors, the color difference is serious, and it is easy to cause more than three color differences in the silk yarn on the fabric dyed in a cylinder, making the fabric unusable

Subsequent repairs not only cause a lot of waste, but also cause damage to the fabric

[0008] Since the warp willow problem occurs in the warp direction and runs through the entire fabric, it is more difficult to solve than the problem in the weft direction, and the loss is greater

The willow problem cannot be seen before dyeing, but it will appear on the fabric after dyeing, which is difficult to avoid with existing technologies
