Abstract

The invention discloses an environmentally-friendly desizing agent used for high-density polyester fabric. The environmentally-friendly desizing agent is prepared from, by weight, 3-6 parts of sodium hydroxide, 2-5 parts of sodium percarbonate, 1-3 parts of sodium bromite, 1.5-3 parts of tetraacetyl ethylenediamine,5-10 parts of cellulose compound enzyme, 2-3 parts of calcium chloride, 1-4 parts of secondary alkyl sodium sulfonate, 5-8 parts of n-butyl acetate, 1-2.5 parts of alkali lignin, 1-2 parts of a buffering agent, 0.5-1.5 parts of a penetrating agent and 20-50 parts of deionized water. The invention further discloses a preparation method of the environmentally-friendly desizing agent. The desizing agent is good in desizing effect, excellent in acid and alkali resistance, free of damage to the fabric and small in usage quantity, cleaning is easy, the yield of waste water is low, and no pollution is generated; the preparation method is simple, the raw materials are easy to obtain, the price is low, and the production cost is low.

Description

Technical field: [0001] The invention relates to the field of textile auxiliaries, in particular to an environment-friendly desizing agent for high-density polyester fabrics. Background technique: [0002] Since its invention, polyester has achieved rapid development with its absolute advantages. Its quantity has accounted for 1 / 3 of the world's textile fibers and about half of my country's textile fiber processing volume. It has become a leader in synthetic fibers and is an ideal textile fiber today. Material. Polyester filament is the main raw material of my country's silk industry. my country's annual silk production has reached 8 to 9 billion m, of which the output of synthetic fiber silk accounts for more than 80%, and most of them are polyester filaments. Therefore, polyester filaments play an important role in the silk industry. The annual application volume of synthetic fiber simulation silk has reached more than 1 million tons; my country's annual export of synthetic...
