Abstract

The invention discloses a composite acid reduction cleaning agent containing sodium hydrogen sulfite and rongalite, and relates to the technical field of dyeing and finishing. The composite acid reduction cleaning agent is prepared from the following components of 0.2 to 0.9g / L of sodium hydrogen sulfite, 0.1 to 0.6g / L of rongalite, 0.1 to 0.4g / L of AEO-9, and water. The invention also discloses apreparation method and application of the composite acid reduction cleaning agent containing the sodium hydrogen sulfite and the rongalite. The composite acid reduction cleaning agent containing thesodium hydrogen sulfite and the rongalite has the advantages that the cleaning effect is good, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing, in particular to a sodium bisulfite dibasic compound acid reduction cleaning agent, its preparation method and its application. Background technique [0002] After the polyester fabric is dyed with disperse dyes, it needs to be reduced and cleaned with sodium hydrosulfite and caustic soda. The traditional caustic soda and sodium hydrosulfite reduction cleaning process is as follows: 1) cooling down the dye solution and draining the liquid; 2) alkaline reduction cleaning, using 2g / L, caustic soda 2g / L, at 80°C for 20min; 3) Drainage; 4) Hot water washing; 5) Drainage; 6) Water washing; 7) Drainage; 8) Pickling; 9) Drainage; 10) drying. But this reduction cleaning method has the following disadvantages: (1) sodium hydrosulfite has certain dangers in the storage process, and it is easy to explode if stored improperly; (2) hydrosulfite will react violently with water during use, releas...
