1. What are textile auxiliaries?

Textile auxiliaries are chemicals used in the processing of textiles to improve the processability, dyeability, functionality or final performance of fibers. They include pre-treatment agents, dyeing auxiliaries, finishing agents, etc., which can improve the softness, waterproofness, antibacterial properties of fabrics.

2. Are textile auxiliaries safe and environmentally friendly?

Modern textile auxiliaries pay more and more attention to environmental protection, and many manufacturers have developed low-toxic and biodegradable products (such as plant-based dyes and fluorine-free waterproofing agents). However, the specific safety must comply with international standards, and it is recommended to choose certified auxiliaries.

3. Why do we need antimicrobial finishing agents?

Antimicrobial auxiliaries can inhibit the growth of bacteria and fungi, reduce odor and infection risks, and are suitable for sportswear, medical textiles and daily household items. Its mechanism of action is usually achieved by destroying the cell membrane of microorganisms.

4: Is hydrogen peroxide stable or unstable?

Hydrogen peroxide is unstable and easily decomposes into oxygen and water, releasing heat. Although not flammable, it is a strong oxidant and can cause spontaneous combustion when in contact with organic matter.

5: How do you keep hydrogen peroxide stable?

To maximize shelf life, store hydrogen peroxide in a cool, dry place. Do not open unless needed; once opened, store in the original brown bottle. The bottle is designed to prevent light from accelerating its decomposition.

6: What is the role of peroxide stabilizers?

Hydrogen peroxide bleach stabilizers play an important role in obtaining high-quality bleached products by inhibiting the rapid decomposition of hydrogen peroxide to achieve uniform bleaching.

7: What are the three stages of dyeing?

The dyeing process is divided into three stages: dye molecules attach to the fiber surface, penetrate into the intermolecular space, diffuse in the fiber, and orient along the long-chain molecules (and fixation).

8: What are dyeing auxiliaries?

Dyeing auxiliaries refer to chemicals or formulated chemicals that enable the dyeing process to be carried out more efficiently. Dyeing auxiliaries include fixing agents, cationizing agents, dispersants, and leveling agents, etc.

9: What does exhaustion of dyeing auxiliaries mean in textile processing?

In exhaustion, the fabric is made to absorb dye and come into contact with the dye bath by optimizing the use of dyeing auxiliaries. Therefore, the rate and extent of dyeing depends on the exhaustion rate of the dye bath. We ensure exhaustion dyeing with environmentally friendly auxiliaries to obtain better fabric properties.

10. How do self-healing coatings work?

This type of additive uses microcapsule technology or dynamic chemical bonds to release repair ingredients (such as polymers) when the fabric is damaged (such as scratches), automatically filling the damage and extending the life of the textile. It is often used in high-end outdoor clothing or industrial fabrics.
