Problems solved by technology

At present, the commercially available disperse dyes can be dyed modified polyester (EDDP) under normal pressure, although the dyeing temperature of disperse dyes can be significantly reduced, but in actual dyeing, it is often necessary to achieve a better deep dyeing effect at more than 100 ° C; while cationic dyes Atmospheric pressure dyeable modified polyester (ECDP) is applied to wool / polyester blended fabrics. In the actual dyeing operation, due to the electrical properties of the applicable dyes, it is impossible to solve the problem of dyeing two fibers in the same bath. Generally, two baths are used for dyeing. But this method also has the following problems: the dyeing process is long, the strength of the fiber after dyeing often decreases significantly, the product quality is low, the energy consumption is large, and the cost is high
Although the disperse cationic dyes currently on the market can alleviate some problems in actual dyeing, they still cannot fundamentally solve the problem of the piece-dyeability of the two fibers

Embodiment 1

[0035] The selected fabric is 180g / m2 2 Super imitation cotton wool blend knitted fabric, fabric composition: 70% super imitation cotton, 30% wool. The monofilament fineness of super-imitation cotton is 1.7dtex. The wool is superfine wool produced in Australia. It is made after peeling and mercerizing to maintain the moisture absorption, breathability and warmth retention functions of wool fiber itself.

[0036] After adding water to the super imitation cotton wool blended fabric at a bath ratio of 1:30, add dissolved Dianix Red E-FB 2.9%, Lansol Red GN 1.05% and Lansol Blue 3R 0.15%, Yuanming powder 6%, Abaig B 1.5%, ammonium sulfate 3%, glacial acetic acid 1.0%, run at a rate of 2°C / min to 40°C for 30 minutes. Then heat up to 95°C at a rate of 1°C / min, run for 50 minutes, then drop to 50°C at 2°C / min, drain water, wash with water twice, and finally soap wash, wash with water, dry the dyed fabric or dry after functional finishing.

Abstract

The invention discloses a dyeing method of a super imitation cotton wool blended fabric. By comparing the shades of super-imitation cotton samples dyed by disperse dyes at different temperatures, the red, yellow and blue disperse dyes suitable for dyeing super-imitation cotton were screened out. Add disperse dyes, leveling agent, sodium sulfate, reactive dyes for wool or acid dyes, adjust the pH value and then dye to obtain dyed super imitation cotton and wool blended fabrics. Through the above method, the present invention provides a method for dyeing super-imitation cotton-wool blended fabrics. Dyeing is carried out under normal pressure conditions. The structure and performance of the copolyester fiber can ensure the dyeing of the two fibers, and the low-temperature dyeing energy consumption is low, which can meet the requirements of small batch production and multiple varieties. In addition, the one-bath dyeing process is adopted, the production cycle is short and the production cost is low.

Description

technical field [0001] The invention relates to the field of dyeing and finishing of textile fabrics, in particular to a method for dyeing super-imitation cotton-wool blended fabrics. Background technique [0002] Wool / polyester blended fabric combines the advantages of wool and polyester fibers to a certain extent, and is a popular textile in the market. In order to achieve the ideal dyeing effect and color in the same bath dyeing of two kinds of fibers, the dyes, auxiliaries and process conditions used for dyeing of the two kinds of fibers should not conflict with each other, and there should be no obvious adverse effects on each other. Color fastness, vividness, shade, etc. must meet the quality requirements. However, wool is generally boiled with acid dyes, while conventional polyester fibers usually need disperse dyes for high temperature and high pressure dyeing. Under such dyeing conditions, wool fibers will suffer great damage, thereby reducing some of the qualities...
