Embodiment 1

[0013] The components and weight percentages of the phosphorus-free scouring agent are as follows:

[0014] Isomerized C8 alcohol ether (6EO) carboxylate 15%, C8-10 alkyl glycoside 15%, isomerized C8-10 alcohol polyoxyethylene ether (3EO) 10%, deionized water 60%.

Embodiment 2

[0016] The components and weight percentages of the phosphorus-free scouring agent are as follows:

[0017] Isomerized C10 alcohol ether (3EO) carboxylate 18%, C8-10 alkyl glycoside 14%, isomerized C10-12 alcohol polyoxyethylene ether (5EO) 8%, deionized water 60%.

Embodiment 3

[0019] The components and weight percentages of the phosphorus-free scouring agent are as follows:

[0020] Isomerized C13 alcohol ether (5EO) carboxylate 25%, C10-12 alkyl glycoside 10%, isomerized C13-15 alcohol polyoxyethylene ether (6EO) 5%, deionized water 60%.

[0021] The isomeric C8 alcohol ether (6EO) in the above example 1 specifically refers to the product obtained by adding isomeric C8 alcohols to 6 EO (ethylene oxide), and other similar expressions also refer to this meaning.

[0022] The preparation method of the phosphorus-free scouring agent of above-mentioned three embodiments is:

[0023] Put the isomeric alcohol ether carboxylate, alkyl glucoside, isomeric alcohol polyoxyethylene ether and deionized water into the reaction kettle according to the formula ratio, and stir and mix for 20-40 minutes at normal pressure and 40-50°C , cooling, filtering and packaging to obtain the product.

Abstract

The invention discloses a scouring agent for fabric pretreatment and a preparation method thereof. Most of the existing products contain phosphate or other phosphorus substances which directly causes phosphorus environment pollution and water body eutrophication. The preparation method comprises the following steps: putting isomerous alcohol ether carboxylate, alkyl glucoside, isomerous polyoxyethylene ether and water into a reaction kettle according to a formulation proportion, stirring and mixing the mixture for 20 to 40 minutes within 40 to 50 DEG C at normal pressure, and preparing the non-phosphate scouring agent. The scouring agent does not contain phosphorus elements or APEO and has excellent alkali resistance, excellent alkali penetrability and excellent emulsifying dispersivity, therefore, the non-phosphate scouring agent has high efficiency and protects the environment.

Description

technical field [0001] The invention relates to an auxiliary agent for fabric pretreatment, in particular to a scouring agent and a preparation method thereof. Background technique [0002] The purpose of the pretreatment of cotton, linen and their blended fabrics is to remove natural impurities such as pectin, wax, cotton seed hulls and chemical impurities such as oils and sizing on the fabrics, reduce the impurity content on the fabrics, and improve the water absorption properties of the fabrics. BaiDu. No matter what pretreatment process is adopted, the corresponding scouring agent must be used to ensure the quality of refining and bleaching. After rapid development in recent years, the current scouring agents can basically meet the scouring requirements such as fast penetration, sufficient emulsification and dispersion, and clean impurity removal, but there are phosphate ingredients in the products. Cause environmental phosphorus pollution, leading to eutrophication of...
