Scouring Agent

Inquiry

Scouring agents are essential chemical auxiliaries widely used in the textile industry to cleanse fibers and fabrics. This primary cleaning process eliminates natural and synthetic impurities, such as waxes, pectins, and oils, that adhere to textiles. Our scouring agents include:

Catalog	Product Name	pH	Note
DYE-AUX-0051	Low Temperature Scouring Agent A	4.0-6.0	Suitable for the cold pad-batch, continuous scouring, and oxygen bleaching pre-treatment processes of pure cotton and its blended woven fabrics. Exhibits excellent penetration, emulsification, and dispersion properties at low temperatures. This concentrated product can be used directly and can be diluted 1-3 times in an automatic feeding system. Dosage: Dipping 0.5-2.0%; Cold pad-batch 8-12 g/L.
DYE-AUX-0052	Low Temperature Scouring and Bleaching Agent	6.0-8.0	Suitable for the alkaline-oxygen one-bath pretreatment process of cotton, polyester-cotton knitted fabrics, towels, yarn packages, and hank yarns. It can bleach cotton fabrics at 70℃. The reaction is gentle, causing minimal strength degradation. It features low energy consumption and low water usage, thus shortening the process time. Dosage: 1-3 g/L.
DYE-AUX-0053	Low Temperature Scouring Agent B	5.0-7.0	Suitable for the low-temperature scouring and bleaching of cotton-polyester and cotton woven fabrics in pre-treatment processes. This product is a combination of low-temperature bleaching agent and scouring agent. It is a concentrated, low-foam product. Dosage: 3-10 g/L.
DYE-AUX-0054	Highly Effective Scouring Agent A	6.0-8.0	Suitable for the pretreatment of cotton and its blended fabrics. It has excellent alkali permeability and stability in a 0-180 g/L sodium hydroxide aqueous solution. Dosage: Scouring 7-12 g/L; Cold pad-batch 7-15 g/L.
DYE-AUX-0055	Highly Effective Penetrant Scouring Agent	5.0-7.0	Suitable for the pretreatment of cotton and its blended fabrics. It has excellent alkali permeability and stability in a 0-180 g/L sodium hydroxide aqueous solution. Dosage: Scouring 4-8 g/L; Cold pad-batch 5-12 g/L.
DYE-AUX-0056	Highly Effective Scouring Agent B	6.0-8.0	Suitable for the pretreatment of cotton and its blended fabrics. It has excellent alkali permeability and stability in a 0-200 g/L sodium hydroxide aqueous solution. Dosage: Scouring 7-12 g/L; Cold pad-batch 7-15 g/L.

Catalog	Product Name	pH	Note
DYE-AUX-0057	Highly Effective Scouring Agent C	6.0-8.0	Suitable for the pretreatment of cotton and its blended fabrics. Exhibits excellent alkali resistance, penetration, and stability in sodium hydroxide solutions ranging from 0 to 220 g/L. Dosage: Scouring 5-10 g/L; Cold pad-batch 5-15 g/L.
DYE-AUX-0058	Highly Effective Scouring Agent D	7.0-8.0	Suitable for the continuous steaming pre-treatment of cotton, linen, and their blends or interwoven fabrics. It has excellent wetting, emulsification, and dispersing abilities. It remains stable in a sodium hydroxide aqueous solution with a concentration of 0-120 g/L. Dosage: Scouring 5-10 g/L, Cold pad-batch 5-15 g/L, Caustic-oxygen one-bath 0.5-2% (o.w.f).
DYE-AUX-0059	Multi-Functional Scouring Powder A	≥ 10.5 (1‰)	Suitable for the pre-treatment of cotton, polyester-cotton fabrics, and yarns in an alkaline-oxygen one-bath process. It integrates functions of alkalinity, refining, penetration, and chelation. Easy to use, it features low weight loss and good compatibility. Dosage: Alkaline-oxygen one-bath 2-3 g/L.
DYE-AUX-0060	Multi-Functional Scouring Powder B	≥ 11.0 (1‰)	Suitable for the alkali-oxygen one-bath pretreatment process of pure cotton, polyester-cotton fabrics, and yarns. Combines functions of alkali, scouring, penetration, and chelation. Easy to use, low weight loss rate. Dosage: Alkali-oxygen one-bath 2-3 g/L, Cold stacking 20-30 g/L, Alkali-oxygen one-bath steaming 20-30 g/L.
DYE-AUX-0061	Scouring Agent A	5.0-7.0	Suitable for the continuous steaming pretreatment of cotton, linen, and their blended fabrics, or the continuous dyeing process of denim yarns. It exhibits excellent resistance to high-temperature alkali boiling and electrolytes, reducing impurity adhesion to rollers and extending cleaning intervals. When used in the continuous dyeing of denim yarns, it can increase the liquid retention rate and enhance the color yield. Dosage: Scouring: 2 - 10 g/L; Caustic-Oxygen One-Bath Process: Cold Pad-Batch: 5 - 12 g/L, Combined Desizing and Bleaching: 5 - 10 g/L; Denim Yarn Continuous Dyeing: 5 - 8 g/L.
DYE-AUX-0062	Scouring Agent B	≥ 10.5 (1‰)	Combines functions of alkali agent, scouring, penetration, and chelation in one. Easy to use, with a low fabric weight loss rate. Dosage: 1-5 g/L.

Advantages of Scouring Agents

Enhanced Dye Uniformity: The thorough cleaning achieved by scouring agents leads to more even dye uptake in textiles, resulting in vibrant and consistent color distribution across the fabric.
Improved Fabric Hand and Texture: By removing impurities, scouring agents help to enhance the hand and feel of the fabric, making it softer and more comfortable to wear.
