Problems solved by technology

The traditional pretreatment process is long, consumes a lot of resources such as water and electricity, and at the same time removes a large amount of sewage and pollutants, which does not meet the current development trend of water-saving printing and dyeing.
In addition, the traditional pre-treatment process does not take into account the felting of wool fabrics, resulting in large dimensional deformation of wool fabrics

Abstract

The invention discloses a wool fabric dyeing pre-treating technology. The technology comprises the shrinkproof step, the washing step and the sizing step; according to the shrinkproof step, bio-enzyme-protease composite chloride-free shrinkproof treatment is adopted, an adopted bio-enzyme-protease composite chloride-free shrinkproof finishing solution is prepared from, by mass, 8-12% of sodium hydrogen sulfite, 15-18% of bio-enzyme, 10-15% of protease, 5-10% of organic silicone softener, 20-25% of acrylic resin and 30-40% of water. The technology is simple and easy to control, has the advantages of being low in water and electricity consumption, saving energy and reducing emission, conforms to the printing and dyeing industry development trend, and is wide in market prospect.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a wool fabric dyeing pretreatment process. Background technique [0002] Traditional wool fabrics need to undergo high-temperature pre-treatment before dyeing to remove textile oil stains, stains, sizing, etc., and then undergo washing and neutralization processes after pre-treatment to avoid the occurrence of pre-treatment of knitted fabrics. Translucence, unevenness and unclean alkali removal lead to problems such as white spots on the cloth surface, blooming and uneven slivers during dyeing. The traditional pretreatment process is long, consumes a lot of resources such as water and electricity, and removes a large amount of sewage and pollutants at the same time, which does not meet the requirements of the current development trend of water-saving printing and dyeing. In addition, the traditional pre-treatment process does not take into account the felting...
