Embodiment 1

[0018] The components of the scouring agent in this example are proportioned by mass as follows: cellulase (produced by Ningxia Heshibi Biotechnology Co., Ltd.): 0.2 parts, acid pectinase (produced by Shouguang Luke Chemical Co., Ltd.): 0.4 parts, Alkaline pectinase (produced by Ningxia Hersbit Biotechnology Co., Ltd.): 0.9 parts, trimethylolpropane: 5 parts, polyethylene glycol: 2 parts, difatty acyl ethylenediamine dipropionate sodium: 3 parts , sodium hydroxide solution: 16 parts, calcium chloride: 5 parts, hydrogen peroxide: 9 parts, soap flakes: 5 parts, deionized water: 60 parts. Wherein, the mass percentage concentration of sodium hydroxide solution is: 15%. The volume percent concentration fraction of hydrogen peroxide in hydrogen peroxide is 25%.

Embodiment 2

[0020] The scouring agent components of this embodiment are proportioned as follows by mass: cellulase: 0.3 parts, acid pectinase: 0.6 parts, alkaline pectinase: 1.2 parts, trimethylolpropane: 6 parts, polyethylene glycol : 3 parts, sodium bis-acyl ethylenediamine dipropionate: 4 parts, sodium hydroxide solution: 25 parts, calcium chloride: 9 parts, hydrogen peroxide: 10 parts, soap flakes: 6 parts, deionized water: 70 parts . Wherein, the mass percentage concentration of sodium hydroxide solution is: 16%. The volume percent concentration fraction of hydrogen peroxide in hydrogen peroxide is 26%.

Embodiment 3

[0022] The scouring agent components in this embodiment are proportioned by mass as follows: cellulase: 0.25 parts, acid pectinase: 0.5 part, alkaline pectinase: 1 part, trimethylolpropane: 5.5 parts, polyethylene glycol: 2.6 parts, sodium bis-acyl ethylenediamine dipropionate: 3.4 parts, sodium hydroxide solution: 20 parts, calcium chloride: 8 parts, hydrogen peroxide: 9.5 parts, soap flakes: 5.5 parts, deionized water: 65 parts. Wherein, the mass percentage concentration of sodium hydroxide solution is: 15.5%. The volume percentage concentration fraction of hydrogen peroxide in hydrogen peroxide is 25.5%.

[0023] Experiments have shown that using the above three scouring agents as additives to participate in the scouring of cotton fiber fabrics, the effect of removing pectin and cleaning effect of cotton fibers is very good, and the flexibility of the fabric is improved.

Abstract

The invention relates to a scouring agent suitable for cotton textile, which comprises the following components: cellulase, acidic pectinase, alkaline pectinase, trimethylol propane, polyethylene glycol, alkanediyl-alpha,omega-bis(sodium N-acyl-beta-alaninate), a sodium hydroxide solution, calcium chloride, hydrogen peroxide, soap flakes, and deionized water. According to the scouring agent of the invention, acidic pectinase is combined with alkaline pectinase, which improves pectin on the cellulose surface; a few of cellulases are added to improve the textile flexibility; the added trimethylol propane, on one hand, can be used as a promoter of the acidic pectinase and the alkaline pectinase, and one the other hand, can improve the hear resistance of cellulase and prolong the living half life. In addition, the alkanediyl-alpha,omega-bis(sodium N-acyl-beta-alaninate) added into the scouring agent is a novel Gemini surfactant, has excellent stability of alkali resistance and hydrogen peroxide resistance, has good emulsibility and strong foaming capability, and thus improves the scouring effect.

Description

technical field [0001] The invention relates to a textile scouring agent, in particular to a scouring agent suitable for cotton fabrics. Background technique [0002] When cotton fiber grows, it is accompanied by natural impurities (pectic substances, waxy substances, nitrogenous substances, etc.). After the cotton fabric is desized, most of the size and some natural impurities have been removed, but a small amount of size and most of the natural impurities still remain on the fabric. The presence of these impurities makes the cotton cloth surface yellow and poor in permeability. Simultaneously, owing to the existence of cottonseed shell, has influenced the appearance quality of cotton cloth greatly. Therefore, it is necessary to scorch the fabric for a long time in high-temperature concentrated lye to remove residual impurities. Scouring is the use of caustic soda and other scouring aids to undergo chemical degradation reactions or emulsification, puffing, etc. with pect...
