Processing Characteristics

A)    Cellulose fiber fabrics

The following characteristics can be obtained by using the resin and YT in combination to process cellulose fiber strong products:

1. High wrinkle and shrink resistance, durable and washable;
2. Durable mechanical processing performance after washing;
3. The tension caused by resin processing is minimized, and it has good resistance to chlorine;
4. Increases the wash fastness of many direct dyes;
5. Enhances resistance to hydrolysis caused by acid or releasing acid substances;
6. Does not change color due to heat treatment;
7. Extremely low residual formaldehyde on the fabric surface, greatly reducing the tendency of the product to have a formalin odor during storage after fabric processing;
8. No fishy smell.

B)    Synthetic fibers

The resin can provide the following properties for NYLON, DACRON or other hydrophobic synthetic fibers:

1. Comfortable hand feel;
2. Ideal stiffness and high elasticity;
3. Highly water-resistant and dry-cleaning resistant;
4. No surface resin phenomenon;
5. No odor during storage period;
6. Reduced mechanical processing problems and pollution.

Instructions for Use

1. Fabric conditions: The fabric must be clean and must not contain any substance that can hinder resin penetration, normal processing and bath stability, such as acid, alkali, salt or other substances.
2. Bath preparation: There are no special precautions or techniques for bath preparation, since this product can be dissolved in water in any proportion at room temperature. The choice of catalyst depends on the heat treatment equipment and processing method;
3. Catalyst compatibility: Catalysts such as YT-01, YT-02, YT-03 can be used.
