Pretreatment Agent – Chelating Dispersing Agent & Oxygen Bleaching Stabilizers
| Chelating Dispersing Agent & Oxygen Bleaching Stabilizers | |
| Chelated dispersants
Crosquest HRO |
|
| Ionicity: Anionic
Dosage: 1-2g/L Target: Cellulose fibers and their blended products |
Efficiently chelate calcium and iron ions;
Improve the scouring and bleaching effects of cellulose products; Particularly suitable for use under alkaline conditions. |
| Continuous process hydrogen peroxide stabilizer
Crosprep SF-CS |
|
| Ionicity: Anionic
Dosage: Continuous and cold-rolled batch: 6-12g/L Batch bleaching: 0.2-0.6g/L Target: Cotton and its blended products, flax and its blended products |
Non-silicon organic hydrogen peroxide stabilizer;
Particularly suitable for continuous pre-treatment processes, it can effectively control the decomposition of hydrogen peroxide under severe bleaching conditions; It can obtain the best fabric whiteness and the least fabric damage; Excellent dispersibility. |
| Modified sodium silicate hydrogen peroxide stabilizer
Crosprep MSS |
|
| Ionicity: anionic
Dosage: Continuous and cold-rolled batch: 8-20g/L Object: cellulose fiber and its blended products |
The modified sodium silicate system can be used for continuous and semi-continuous bleaching;
It has strong dispersibility, which reduces the problems of equipment contamination and hard fabric feel caused by the precipitation of insoluble calcium and magnesium silicates; It has excellent dispersibility for cotton wool and dirt particles, which can make the fabric clean and thus improve whiteness. |
