Embodiment 1

[0011] A fabric printing and dyeing pretreatment process, including the steps of seaming, singeing, scouring and bleaching. During scouring, the singeed gray fabric is treated with an environmentally friendly printing and dyeing auxiliary. The environmentally friendly printing and dyeing auxiliary is Composed of the following components by mass: 25 parts of fatty alcohol polyoxyethylene ether, 20 parts of alkyl alcohol ether carboxylate, 8 parts of diacetone alcohol, 5 parts of ethyl salicylate, isopropyl salicylate 8 parts, 12 parts of sodium sulfonate, 8 parts of ammonium carbonate, 4.5 parts of sodium hydroxide, 2 parts of sodium chloride, 2.5 parts of sodium carbonate and 55 parts of deionized water

Embodiment 2

[0013] A pre-treatment process for fabric printing and dyeing, including the steps of seaming, singeing, scouring and bleaching. During scouring, the singeed gray fabric is treated with an environmentally friendly printing and dyeing auxiliaries. The environmentally friendly printing and dyeing auxiliaries are Composed of the following components by mass: 30 parts of fatty alcohol polyoxyethylene ether, 20 parts of alkyl alcohol ether carboxylate, 10 parts of diacetone alcohol, 3 parts of ethyl salicylate, isopropyl salicylate 5 parts, sodium sulfonate 12 parts, ammonium carbonate 8 parts, sodium hydroxide 3 parts, sodium chloride 5 parts, sodium carbonate 5 parts and deionized water 60 parts.

Embodiment 3

[0015] A pre-treatment process for fabric printing and dyeing, including the steps of seaming, singeing, scouring and bleaching. During scouring, the singeed gray fabric is treated with an environmentally friendly printing and dyeing auxiliaries. The environmentally friendly printing and dyeing auxiliaries are Composed of the following components by mass: 20 parts of fatty alcohol polyoxyethylene ether, 15 parts of alkyl alcohol ether carboxylate, 10 parts of diacetone alcohol, 5 parts of ethyl salicylate, isopropyl salicylate 5 parts, sodium sulfonate 15 parts, ammonium carbonate 10 parts, sodium hydroxide 6 parts, sodium chloride 5 parts, sodium carbonate 3 parts and deionized water 50 parts.

[0016] The invention uses the environmental protection printing and dyeing auxiliaries to process the singeed gray cloth during scouring. The environmental protection printing and dyeing auxiliaries integrate multiple functions, which can make the gray cloth better treated, make it eas...

Abstract

The invention discloses a fabric printing and dyeing pretreatment process. The fabric printing and dyeing pretreatment process comprises the steps of seam allowance releasing, singeing, boiling off and bleaching. In the boiling off, a singed gray fabric is treated by using an environmentally-friendly printing and dyeing aid. The environmentally-friendly printing and dyeing aid consists of the following components in parts by mass: 20-30 parts of fatty alcohol-polyoxyethylene ether, 15-25 parts of alkyl alcohol ether carboxylate, 5-10 parts of diacetone alcohol, 3-6 parts of ethyl salicylate, 4-10 parts of isopropyl salicylate, 10-15 parts of sodium sulfonate, 5-10 parts of ammonium carbonate, 2-6 parts of sodium hydroxide, 1-5 parts of sodium chloride, 1-5 parts of sodium carbonate and 50-60 parts of deionized water. Through the mode, the environmental pollution in a printing and dyeing process is reduced.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a pretreatment process for fabric printing and dyeing. Background technique [0002] Fabrics that have not been dyed and finished are collectively referred to as raw fabrics or gray fabrics. The purpose of the pre-printing and dyeing treatment is to remove all kinds of impurities on the fabric with little damage to the gray fabric, so that the gray fabric becomes a white, soft and printing and dyeing semi-finished product with good wetting properties. Pretreatment of printing and dyeing is the preparatory process of printing and dyeing processing, also known as scouring and bleaching. For the pretreatment of cotton and cotton-type fabrics, there are processes such as preparation, singeing, desizing, scouring, bleaching, and mercerizing. Some existing pretreatment liquids of printing and dyeing processes, due to the low coupling rate of dye groups and fibers, low adso...
