Problems solved by technology

The disadvantages are: 1. The cohesion between modal fibers is low, it is easy to wash the hair, it is more sensitive to the amount of soda ash additives of sodium sulfate, and it is more difficult to dye the bobbins; 2. The proportion of the amorphous area of ​​the modal fibers is large, and the dye diffuses Fast, easy to produce colored flowers, strong affinity for reactive dyes, high initial dyeing rate, short half-dyeing time, dyes are not easy to migrate once dyed, and the shade is difficult to control; 3. Modal jeanette fabrics are produced after finishing Chicken paw prints, scratches and other problems are easy to appear during the process, especially for dark-colored varieties

Embodiment 1

[0033] Fabric specification: 120*90 30 Modal + 40 Modal * 30 Modal + 40 Modal. The fabric has a certain thickness and tightness, which makes it feel like suede. The use of two yarn counts is mainly to improve the three-dimensional effect of the fabric.

[0034] A method for dyeing and finishing full-color modal jeanette yarn-dyed fabric, which is characterized in that the processing steps include: loosening → pre-treatment → dyeing → post-processing → rewinding → warping → sizing → weaving → post-finishing;

[0035] After the tube loosening step, put a sock cover on the tube yarn;

[0036] In the pre-treatment step, use 2g / L scouring agent at 90°C for 30 minutes to fully remove the surface oil and improve the uniformity of yarn dyeing;

[0037] In the dyeing step, the dosage of sodium sulfate is 30-70g / L, and the dosage of soda ash is 5-15g / L. The selected dyes have excellent compatibility, bright and uniform color, and good color reproducibility. For example, RFR yellow, RFB...

[0048] Fabric specification: 120*90 30 Modal+40 Modal*30 Modal+40 Modal.

[0049] A method for dyeing and finishing full-color modal jeanette yarn-dyed fabrics, characterized in that the processing steps include: loosening → pre-treatment → dyeing → post-processing → rewinding → warping → sizing → weaving → post-finishing;

[0050] After the tube loosening step, put a sock cover on the tube yarn;

[0051] In the pre-treatment step, use 2g / L scouring agent at 90°C for 30 minutes to fully remove the surface oil and improve the uniformity of yarn dyeing;

[0052]In the dyeing step, the dosage of sodium sulfate is 30-70g / L, and the dosage of soda ash is 5-15g / L. The selected dyes have excellent compatibility, bright and uniform color, and good color reproducibility. For example, RFR yellow, RFB red, MD blue; the dyeing steps are carried out as follows: Add 1g / L chelating agent at 35°C → pour into the main vat and run for 5 minutes, return to the auxiliary vat to add dye → melt an...

Abstract

The invention provides a dyeing and finishing method of a full-color modal polyester peach skin yarn-dyed fabric and the fabric. The method includes the steps of unwinding, preprocessing, dyeing, postprocessing, rewinding, warping, slashing, weaving and after-finishing; the after-finishing process includes the steps of zero-shrinkage-rate pre-shrinkage, singeing, desizing, water sanding, air washing+enzyme washing, sizing and pre-shrinkage. The method has the advantages that the green cutting problem between modal fiber under the low cohesive force is avoided; treatment is conducted through ascouring agent in the preprocessing step, grease on the modal fiber surface is sufficiently removed, and the dyeing uniformity is improved; dyes excellent in compatibility and high in color light reproducibility are selected in the dyeing step, the dyes, anhydrous sodium sulphate and sodium carbonate are added at a low temperature, and the problem is solved that modal is quite to color and prone to dyeing defects; the shrinkage rate is 0% in the zero-shrinkage-rate pre-shrinkage step, the fabric is ironed, and dead creases are avoided; by means of the fabric sanding process of water sanding and air washing+enzyme washing, the fabric is endowed with the polyester peach skin effect.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, and in particular relates to a dyeing and finishing method of a full-color modal jeanette yarn-dyed fabric and the fabric. Background technique [0002] Peach skin (Micro Fiber Peach) is a thin imitation leather fabric composed of superfine fibers following the artificial suede products. In the dyeing and finishing process, the fine sanding finishing process makes the surface of the fabric tightly covered with fine, uniform and dense fluff like a peach. This fluff seems invisible but can be touched. It diffuses in many directions under the light and is very Soft, with a novel and elegant appearance and comfortable feel, so it is favored by people. Traditional jeanette made from 100% polyester. Modal is a kind of regenerated cellulose fiber, the raw material is natural material, which is harmless to the human body, can be decomposed naturally, and is harmless to the environme...
