Abstract

The invention discloses a method for preparing an environment-friendly natural fiber printing paste, comprising the following steps of: 1) selecting fine diatomaceous earth having a grain size less than or equal to 2 microns; 2) preparing raw printing paste, wherein the raw printing paste is composed of the following components in terms of weight: 6-13% organic printing paste material, 1-8% fine diatomaceous earth and 0.2-0.6% sodium hexametaphosphate, and rest being water; and 3) preparing the printing paste, wherein the printing paste is composed of the following components in terms of weight: 1-4% dye, 1-7% urea, 1-7% urea replacing agent, 1.5-2.5% sodium bicarbonate, 0.2-1% reserve salt S and 50% raw printing paste, and rest being water. The printing paste obtained through the method of the invention is capable of ensuring the printing quality and also capable of greatly reducing the content of organic matters in sewage discharged after printing, thereby reducing pollution.

Description

technical field [0001] The invention belongs to the technical field of textile chemistry, and in particular relates to a preparation method of a low-urea environment-friendly natural fiber fabric printing color paste. Background technique [0002] China is the world's largest producer and exporter of textiles. There are currently about 120,000 textile printing and dyeing enterprises, which are the third largest among the 32 industries in the country. However, the annual wastewater discharge of my country's textile industry ranks fourth among all industries in the country, among which the discharge of printing and dyeing wastewater accounts for 80% of the entire textile industry. The textile printing and dyeing process with high energy consumption, high emissions and high pollution also causes resources and the environment negative impacts that cannot be ignored. Therefore, the popularization and application of eco-friendly, energy-saving and consumption-reducing printing and...
