Problems solved by technology

However, there are certain difficulties and problems in the printing and dyeing process of multi-component blended fabrics.
Bamboo fiber has excellent hygroscopicity, air permeability, comfort, anti-ultraviolet, antibacterial and antibacterial properties, but it has poor elastic recovery, and has the disadvantages of obvious decline in fiber strength after moisture absorption, which brings certain difficulties to dyeing and finishing processing; Polyester fiber is a hydrophobic fiber with a tight structure. There is no specific dyeing group in the molecule, it lacks hydrophilicity, and the degree of expansion in water is low. Its color fastness is fixed and the temperature changes greatly, which brings certain difficulties to dyeing. However, wool has poor alkali resistance, is not suitable for strong alkali and high temperature treatment, and is prone to wrinkles. In addition, wool has a slower dyeing speed and lower dyeing rate than polyester and bamboo fibers.
Therefore, for the dyeing of bamboo polyester wool elastic plain weave blended fabric, because each fiber has a different structure, the degree of absorption of the dye solution is different, and the dyeing performance is different, which is easy to cause difficulty in fabric dyeing, the degree of dyeing is different, and the dyeing rate is not high. The finished product obtained after dyeing is easy to fade later, and the color fastness is not ideal.
[0003] Therefore, there are the problems of uneven dyeing uniformity, low dyeing rate, and color fastness in existing bamboo polyester wool elastic plain weave dyeing

Abstract

The invention discloses a bamboo polyester wool elastic plain weave dyeing process which includes the steps: a, desizing and bleaching a bamboo polyester wool elastic plain weave fabric to obtain a product A; b, cleaning and softening the product A by ultrasonic waves, adding fabric softening agents and water softening agents, and continuously softening the product A twice to obtain a product B; c, placing the product B into a dye coater, dyeing the product B with dye liquor at multiple stages, heating the product B to reach 40-60 DEG C, adding first dye liquor and performing ultrasonic insulation treatment at the first stage, heating the product B to reach 60-70 DEG C, adding second dye liquor and performing ultrasonic insulation treatment at the second stage, heating the product B to reach 70-90 DEG C, adding third dye liquor and performing insulation treatment at the third stage, cooling the product B to 30-40 DEG C and performing insulation treatment to obtain a product C; d, washing and soaping the product C to obtain a product D; e, softening the product D and performing loose finishing and drying to obtain a finished product. The bamboo polyester wool elastic plain weave dyeing process has the advantages of dyeing uniformity, high dye-uptake rate and color fastness.

Description

technical field [0001] The invention relates to a dyeing process, in particular to an elastic plain weave dyeing process of bamboo polyester wool. Background technique [0002] At present, most of the fabrics commonly used in textile fabrics on the market are mainly cotton, polyester, nylon and regenerated cellulose fibers. Although these fabrics can basically meet people's needs, there are also some shortcomings. In recent years, with the continuous emergence of new fibers, multi-fiber composite fabrics are more widely used, such as polyester and wool, silk, acetate fiber, spandex and other fiber blended fabrics, due to the combination of the advantages of various fibers, the fabric has a unique Style, more and more favored by consumers. However, there are certain difficulties and problems in the printing and dyeing process of multi-component blended fabrics. Bamboo fiber has excellent hygroscopicity, air permeability, comfort, anti-ultraviolet, antibacterial and antibact...
