Problems solved by technology

[0006] However, the dyeing effect of natural dyes is poor, and the color fixation of the dyed fabric is low. In order to improve the color fixation, a large amount of soda ash and inorganic salts are usually added during the dyeing process, which brings serious problems for the treatment of printing and dyeing wastewater with high salt content. It is more difficult, such as direct discharge will destroy the ecological environment and lead to soil salinization
[0007] At the same time, when natural dyes are used, some mordants containing metal ions are usually used. Although the use of mordants will

Abstract

The invention discloses a dyeing and finishing process for linen and cotton blended fiber fabric. The dyeing and finishing process comprises preprocessing, pre-sizing, modified processing, dyeing, mordant removing, soaping, color fixing, after finishing, drying, sizing, calendaring and rolling. Helicase, scouring enzyme and alpha-amylase are used for pretreatment, modification treatment is adopted before dyeing, the performance of linen and cotton blended fabric is modified fundamentally, and the dye-uptake rate is increased; the dyeing procedure does not require a large quantity of alkaline substances and inorganic salt, a leveling agent, substitutive alkali, a migration inhibitor and a dispersing agent are added, the dye uniformity is improved, environment pollution is avoided due to use of natural dye, and requirements for environmental protection are met; self-cleaning processing is added in the after finishing procedure, and the self-cleaning capacity, the crease-resistant performance, the washing resistance and the color fastness of the fabric are improved; crease-resistance finishing is added, and the crease-resistant performance of the fabric is improved; the whole process is environment-friendly and pollution-free.

Description

Technical field [0001] The present invention involves a kind of linen -cotton -blended fiber fabric. Background technique [0002] Fiber is divided into chemical fibers and natural fibers. Natural fibers refer to fibers that exist and grow in nature. Chemical fiber is a raw material with natural polymer compounds or artificial synthesis.Fiber and other processes have textile performance fiber. Chemical fiber has the advantages of light resistance, wear resistance, easy washing and dry, not moldy, not insects and other., Dragon belt, rope, fishing net, electric insulation line, medical suture, tire curtain cloth and parachute. [0003] Linen is a pure natural fiber, which has significant characteristics such as sweat absorption, good breathability and harmlessness to the human body; cotton fiber is also a natural fiber, good hygroscopic and breathable, soft and warmTherefore, the fabrics made of two fiber -blended fabrics, namely linen cotton blended fiber fabrics on the market. T...
