Problems solved by technology

With the development and changes of pulp in recent years, some new pulps have appeared in the market, such as: terephthalic acid pulp, referred to as TPA. Easy to stain
In addition, various composite sizings are constantly appearing on the market, which also brings certain difficulties to desizing production. These new or composite sizings decompose or disperse and dissolve in the desizing liquid at high temperature, but during the cooling process Their solubility decreases accordingly, and they are prone to coagulation, resulting in anti-sticking of the cloth surface.
[0005] The desizing and degreasing process of traditional chemical fiber fabrics is basically carried out under alkaline conditions, but chemical fiber dyeing with disperse dyes and acid dyes are all carried out under acidic conditions, as the publication date is November 07, 2012, and the publication number is CN102767097A In the Chinese patent, a processing method for three-proof and easy-care clothing fabrics is disclosed. The processing method is first pre-treated in an alkaline environment to remove the size and excess oil in the spinning process of chemical fiber fabrics, and then Dyeing is carried out in an acidic environment, so desizing and degreasing are followed by a large amount of water washing and acid neutralization, which consumes water and time, increases production costs, increases workload, and is not conducive to energy conservation and environmental protection
[0006] To sum up, at present, there is no one-bath process for desizing, deoiling and dyeing chemical fiber fabrics such as polyester and nylon with excellent performance, energy saving and short process flow, which is carried out under neutral conditions and does not require water washing, acid neutralization, etc. One-bath auxiliary agent for neutral desizing, deoiling and dyeing of chemical fiber fabrics that can be directly dyed after draining the working solution and its preparation method

Abstract

The invention relates to an additive for neutral desizing, oil removing and one-bath dyeing of chemical fiber fabrics and a preparation method thereof. Currently, no additives for neutral desizing, oil removing and one-bath dyeing of chemical fiber fabrics or preparation methods thereof are provided with excellent performance, energy saving, and consumption saving. The additive for neutral desizing, oil removing and one-bath dyeing of chemical fiber fabrics provided by the invention comprises 15-25 parts by weight of ANCconc, 15-30 parts of FMES, 5-15 parts of NPP, 5-10 parts of NA, 5-10 parts of penetrants, and 30-50 parts of water, wherein ANCconc is a surfactant with cleaning and anti-contamination functions, FMES is a sulfonate of fatty acid methyl ester ethoxylate, NPP is an oligomer remover, and NA is a multipurpose dispersant. The additive for neutral desizing, oil removing and one-bath dyeing of chemical fiber fabrics provided by the invention has excellent performance, allows the desizing, oil removing and one-bath dyeing processes of chemical fiber fabrics to be carried out under a neutral condition, and can realize direct dyeing without water washing, acid neutralization, or operating fluid discharge.

Description

technical field [0001] The invention relates to a one-bath auxiliary agent for neutral desizing, oil removal and dyeing of chemical fiber fabrics and a preparation method thereof. Background technique [0002] The commonly used size in the weaving of chemical fiber woven fabrics is polyacrylate, which is an acrylate copolymer size. Since the size contains an ester group—OOOR, it has a certain similarity with polyester molecules containing the same group in structure, so Has a strong affinity for polyester. Polyester itself does not contain impurities, but a small amount (below about 3%) of oligomers exists during the synthesis process. As a desizing and refining process, its main purpose is to remove the oil added during fiber manufacturing and the size added during weaving. Coloring dyes and oil stains and dust contaminated during transportation and storage, if the fabric is desizing and degreasing is not clean or does not desizing and degreasing, it will lead to uneven dy...
