Abstract

The invention provides an enzyme preparation for one-bath process of deoxidizing, polishing and dyeing, relates to an enzyme preparation, in particular to an enzyme preparation for one-bath process of deoxidizing, polishing and dyeing for dyeing and processing cotton fabrics. The invention provides the enzyme preparation for one-bath process of deoxidizing, polishing and dyeing for dyeing and processing cotton fabrics as well as an application thereof. The enzyme preparation for one-bath process of deoxidizing, polishing and dyeing comprises the following components by weight percent: 5-40 percent of deoxyenzyme, 20-80 percent of neutral cellulose, 1-20 percent of non-ionic surface active agent, 0.2-5 percent of sodium benzoate, 0.2-3 percent of citric acid, 0.2-5 percent of sodium citrate and the balance of deionized water. The enzyme preparation for one-bath process of deoxidizing, polishing and dyeing can be used for dyeing and processing cotton fabrics and achieve the aim of combining three steps of deoxidizing, polishing and dyeing into a whole.

Description

technical field [0001] The invention relates to an enzyme preparation, in particular to an enzyme preparation used for the one-bath method of oxygen-removing polishing dyeing in cotton fabric dyeing and finishing. Background technique [0002] The traditional dyeing and finishing process of cotton fabrics is oxygen bleaching→hot water washing to deoxidize→biological polishing→dyeing→finishing. Its oxygen removal method is to wash with hot water, which has low efficiency and high energy consumption. [0003] In recent years, the biological enzyme deoxygenation technology has been developed, and the processing flow has been improved as oxygen bleaching→biological enzyme deoxygenation (without heating)→biological polishing→dyeing→finishing. The use of biological enzymes to remove oxygen saves a lot of water, electricity, steam and time. [0004] Since biopolishing uses biological enzymes to polish the surface of the fabric, ordinary polishing enzymes need to be carried out un...
