Problems solved by technology

[0003] The traditional idea is that the weaving of double-faced wool is relatively loose, which is not suitable for dyeing gray fabrics. It is prone to problems such as felting, difficult color penetration, and impermeable coloring between wool and wool. The resulting products cannot meet the wide performance requirements and cannot adapt to leisure trends. ; In addition, during the dyeing process of light-colored products, coloring problems are prone to occur, which increases production costs

Embodiment 1

[0015] The method of dyeing double-faced fabrics includes the following steps: hemming of grey cloth → dehydration → shrinking → washing → dyeing → setting and drying → fixed width → steaming → raising;

[0016] The dyeing process includes: pretreatment with penetrant → room temperature cleaning → drying → treatment with a leveling agent accounting for 2.1% of the weight of the grey fabric → treatment with a penetrant accounting for 0.9% of the weight of the grey fabric → glacial acetic acid with pH=5.8 Aqueous solution treatment→treatment with ammonium sulfate accounting for 1.1% of the mass of the grey fabric→treatment with an aqueous sulfuric acid solution, the pH of the aqueous sulfuric acid solution=2.4, and then wash.

[0017] Then add the dye, run for more than 20 minutes, heat up to 60±2°C at a rate of 0.6°C / min, then heat up to 70~75°C for more than 20 minutes, and then heat up to 98±2°C for more than 1 hour; add the The soaping agent of 2.2% of the grey fabric mass is hea...

Embodiment 2

[0021] The method of dyeing double-faced fabrics includes the following steps: hemming of grey cloth → dehydration → shrinking → washing → dyeing → setting and drying → fixed width → steaming → raising;

[0022] The dyeing process includes: pretreatment with penetrant → room temperature cleaning → drying → treatment with a leveling agent accounting for 1.9% of the weight of the grey fabric → treatment with penetrant accounting for 1.1% of the weight of the grey fabric → pH=5.5-6.0 Treatment with glacial acetic acid aqueous solution → treatment with ammonium sulfate accounting for 0.9% of the mass of the grey cloth → treatment with aqueous sulfuric acid solution, pH of the aqueous sulfuric acid solution = 2.3 ~ 2.5, and then wash;

[0023] Dyeing method of double-faced fabrics When dyeing light colors, add sodium sulfate which accounts for 5.2% of the weight of the grey fabric and run for more than 15 minutes, then add dye, run for more than 20 minutes, and heat up to 60± at a rate o...

Abstract

The invention discloses a dyeing method of double-faced wool fabric. The dyeing method includes the steps of gray fabric hemming, water removing, milling, wool washing, dyeing, shaping and drying, fabric width setting and fluffing. The technical defect that piece dyeing is not suitable for double-faced wool is overcome through dye-vat dyeing, and the technical problems that the fabric width of a cloth cover is felted, and the color hardly permeates are obviously relieved. Through addition of efficient penetrant, the color of the cloth cover is uniform, the problem of dyeing defects is solved, and the first-grade product rate of the fabric is larger than 99%. Through treatment of a special auxiliary, the problem of dyeing non-permeation between wools in the fabric is solved, and the cloth cover is more uniform.

Description

Technical field [0001] The invention relates to a method for dyeing double-faced woolen fabrics in the textile field, and belongs to the technical field of textiles. Background technique [0002] The traditional preparation process of double-sided woolen fabric is: wool→wool dyeing→spinning→weaving→finishing→double-sided woolen fabric. Traditional craftsmanship needs to select the color first and then weave. The production cycle is long, and the general cycle is about 45 days. [0003] The traditional concept believes that the double-sided weaving is relatively loose, not suitable for grey cloth dyeing, and it is prone to felting shrinkage, the color is difficult to penetrate, and the color between the wool is not transparent. The resulting product cannot meet the broad performance requirements and cannot adapt to the leisure trend. In addition, during the dyeing process of light-colored products, color dyeing problems are likely to occur, which increases production costs. Summar...
