A kind of dyeing method of super imitation cotton real silk blended fabric

Abstract

The invention discloses a dyeing method of a super imitation cotton and real silk 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, wool reactive dyes and glacial acetic acid for temperature rise dyeing, after dyeing at 90-100°C for 40-60 minutes, drain all the dyeing residue, then add water, and then heat up to 70-80°C, add alkali agent within 30-40 minutes, fix the color for 30-60 minutes, and obtain dyed super imitation cotton and silk blended fabric. The dyeing process provided by the invention makes the dyeing process and color control of super imitation cotton and real silk blended fabrics simple and easy, has high dyeing rate, high color fixing rate, greatly improved product color depth, and color fastness reaches 3 to 4 grades , using one-bath dyeing process, short production cycle, low energy consumption, low production cost, can meet the requirements of small batch production and multiple varieties.

Description

technical field [0001] The invention relates to the field of dyeing and finishing of textile fabrics, in particular to a dyeing method of a super imitation cotton and real silk blended fabric. Background technique [0002] Silk has always been called the king of fibers because of its good luster, excellent drapability, soft touch, light and comfortable to wear, and good hygroscopicity, moisture permeability, and ventilation. The anti-ultraviolet effect of silk, good biocompatibility with the skin, and the health care function of silk fiber are incomparable and irreplaceable by any fiber. Silk fiber is a protein fiber and contains 18 kinds of amino acids necessary for the human body, which are almost the same as those contained in human skin. Silk fiber not only has good heat dissipation performance, but also has good warmth retention property. It also has the function of defending against the invasion of harmful gases and resisting harmful bacteria. It can also enhance the...

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 the actual dyeing often needs to be over 100°C to achieve better dark color dyeing effect; and cationic When the dye is dyeable at atmospheric pressure and modified polyester (ECDP) is applied to the piece dyeing of silk / polyester blended fabrics, it still cannot solve the problem of dyeing the two fibers in the same bath. Generally, the two-bath method is used for dyeing, but this method also has many shortcomings. , For example, the dyeing process is too long, the strength of the fiber after dyeing is often significantly reduced, 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
