XP-50

XP-50 is a high-performance cationic dye fixing agent specially developed to improve the wet fastness properties of textiles dyed with reactive and direct dyes. It is widely used in textile dyeing and finishing processes where enhanced wash fastness, rubbing fastness, and color durability are required. XP-50 is suitable for both woven and knitted fabrics and is compatible with common textile processing systems used in Bangladesh.

In the Bangladesh textile and garments industry, maintaining consistent color quality after washing is a major challenge. XP-50 addresses this issue by forming a strong ionic bond between dye molecules and the fabric surface, significantly reducing dye bleeding and color fading during washing and use.

Key Performance Characteristics

XP-50 works by fixing unfixed dye molecules onto the fiber, thereby increasing color retention. It is especially effective on cotton, viscose, and blended fabrics dyed with reactive or direct dyes. The product delivers uniform results without affecting fabric handle or shade when used at recommended dosage levels.

One of the major advantages of XP-50 is its excellent compatibility with existing dyeing processes, making it easy to integrate into post-dyeing treatments. It does not cause yellowing or excessive shade change, which is critical for export-oriented garments.

Applications

Reactive Dye Fixing:
XP-50 significantly improves wash and rubbing fastness of reactive dyed fabrics, making it ideal for garments that require repeated washing.

Direct Dye Fixing:
For direct dyed cotton and viscose fabrics, XP-50 helps lock in color and minimize dye migration.

Garments Washing Units:
Widely used in garments washing plants to improve color durability after enzyme wash, stone wash, or normal wash processes.

Home Textiles:
Suitable for bed sheets, towels, curtains, and other home textile products where long-term color stability is required.

Benefits of Using XP-50

• Improves wash fastness and rubbing fastness

• Reduces dye bleeding and staining

• Enhances color durability and brightness

• Compatible with most reactive and direct dyes

• Easy to apply in exhaust and padding methods

• Suitable for both knit and woven fabrics

Typical Application Method

XP-50 is generally applied in the final finishing stage after dyeing and washing. It can be used in exhaust, padding, or continuous processes depending on the production setup.

Recommended Dosage:
Dosage may vary depending on fabric type, dye depth, and process conditions. Trial testing is always recommended before bulk production.

Bangladesh Textile Industry Relevance

XP-50 is a popular choice among dyeing mills, garments factories, and washing plants across Bangladesh due to its consistent performance and cost-effectiveness. It helps manufacturers meet international buyer requirements for color fastness and fabric quality, especially for export markets.

Storage & Handling

Store XP-50 in a cool, dry place away from direct sunlight. Keep containers tightly closed when not in use. Under proper storage conditions, the product maintains stable performance over its shelf life.

Safety & Usage Note

XP-50 is intended for industrial textile processing use only. Operators should follow standard safety procedures, including the use of protective gloves and eye protection during handling.
