Features
High efficient scouring agent YY-L is especially suitable for desizing, scouring and bleaching of cotton fabric Excellent wetting and emulsifying effect in all temperature ranges; has excellent suspending and dispersing ability; Can give the fabric high water absorption and the best whiteness; and has good compatibility with enzyme desizing fluid; suitable for various bleach processing technology; Resistance to static caustic solutions up to 120g/l; Stable and highly effective in dynamic lye up to 150-300g/l. 
 

Uses 
High efficient scouring agent YY-L is a kind of environmental protection pretreatment assistant compounded by many chemical products. It is mainly used for semi-bleaching/bleaching finishing of cotton yarn, cotton cloth and general cotton fabric before dyeing. After being treated by the high-efficiency scouring agent YY-L, impurities, waxes, pulp, natural salt, natural color and the like in the cotton fabric can be effectively removed, so that the surface of the fabric is smooth, the whiteness is improved, the hand feeling is soft and smooth, and the appearance is good; experiments prove that the hydrophilicity and the water absorption diffusivity of the treated fabric are obviously improved, the dyeing rate and the levelness of the dyeing process can be correspondingly improved, and the dyeing is convenient. 
The product effectively reduces the working hours, reduces the production cost, improves the production efficiency, simultaneously, can also increase the safety guarantee of the dyeing production, greatly reduces the sewage discharge, and plays a role in protecting the ecological environment. Harmless to human body and non-hazardous. nbsp;
 

Property

Instructions for use 
For thick cotton fabrics, bath ratio 1:10, can add 2.0%(o.w.f) high-efficiency scouring agent YY-L, at 90-100℃ temperature range for 45-60 minutes; 
For ordinary fabrics, the bath ratio is 1:10, and 1.5%(o.w.f) of high-efficiency scouring agent YY-L can be added, and the treatment is carried out at a temperature range of 90-100 DEG C for 45-60 minutes; 
hot was (60. degree. C.) once and normal temperature washing once, clean twice in total, then adjusting PH value to normal state for deoxygenation and dyeing process; 
For cheese yarn, bath ratio 1:8, can add 1.5-2.0%(o.w.f) efficient scouring agent YY-L, at 90-100℃ temperature range cycle processing for 60 minutes,(with penetrating agent better effect). 
 

Product evaluation reports 
High efficiency scouring agent YY-L is suitable for hydrogen peroxide bleaching of cotton, spandex/cotton, Tencel, ramie and their blended fabrics. 
Bleaching (semi-bleaching) process and recommended dosage 
Efficient scouring agent YY-L 1.5-2.0g/l
Oxygen bleaching stabilizer 1.0-2.5g/l
NaOH 100% 1.0-2.0g/l
Hydrogen peroxide (30%) 6.0-8.0g/l
Bath ratio 1:10
Dyeing machine water into the cloth → add efficient scouring agent YY-L (Dissolve the high-efficiency scouring agent YY-L in warm water in the feeding tank) → heat the dyeing machine to 40-50℃, add oxygen bleaching stabilizer (common dosage in the factory) → add hydrogen peroxide (common dosage in the factory), heat to 90-100℃, treat for 60 minutes (the time should be matched with the machine speed and cloth quality) → drain → wash once with hot water (60-70℃)(15 - 20 minutes) → drain → wash once with cold water (15 - 20 minutes) → drain → water: Adjust pH6-7 (add deoxygenase) → add dye 
 

Technical and economic analysis 
simplify that bleaching proces, reducing the types of auxiliary agents, transport and warehouse occupation, and reducing the weighing times 
in that bleach process, as a plurality of auxiliary agent are reduced, a plurality of side effects such as fiber damage and the like are reduce, and the capillary effect and the hydrophilicity are improved. 
Because the dyed product has uniform bottom bleaching and good levelness, the dyed product can avoid color stain, is easy to wash after bleaching, reduces washing times, and saves water, electricity, steam and labor.
