Polyester/Nylon Composite Fiber Swelling Agent

Polyester/Nylon Composite Fiber

Swelling Agent

HOLPOSON® Swell-Up

HOLPOSON® Swell-Up falls in the category of swelling and splitting technology of macromolecular composite fiber, which is also called densifying technology of PA6 fiber. After treatment, the internal space of the fiber is expanded to a large extent. This technology greatly improves the internal space of the fabric and the unique performance of the fabric. The increase of the specific surface area, the enhancement of the chemical adsorption performance after swelling and splitting, and the physical adsorption capability have all been greatly improved. For some special industries provides raw materials and technical solutions.

The working principle of ultra-high densification of composite fiber: Taking the advantage of the difference between the swelling lengths of polyester fiber and polyamide 6 fiber under different conditions to split the two components to produce ultra-thin size. The swelling rate of polyamide 6 is high in the range of pH 5.0-6.0, while the swelling rate of polyester remains unchanged in acidic conditions. With this advantage, the polyamide after chemical reaction swells extensively and crimps, thus separating itself from polyester.

Usage:

1. Overflow machine process as an example

After the working solution reaches 70℃, add Swell-Up 70-80g/L. Keep the temperature at 102-105 ℃ for 30-50min.

2. Dilution method

Take the specified amount of Swell-Up, take three times the amount of water, gradually add in Swell-Up at 60-70℃, then adjust to the desired volume, stir evenly to form super fine emulsion, finally add it in the dye vat.

3. Swelling fiber process

Process recipe: Swell-Up 70-80g/L

Process conditions: 102-105 ℃ * 30-50 minutes

4. Process flow

The whole process of swelling and splitting of polyester / nylon composite fiber: cloth feeding → degreasing → alkali content → neutralization and water washing →

Swelling → odor removal treatment → hot water washing → dehydration → stenting and setting →final product

Characteristics:

1. This product adopts a special swelling technology;

2. Improve the internal space structure and PA6’s macromolecular structure. Increases the amorphous area of crystallization area;

3. It can effectively swell and split the knitted fabric, woven fabric and other fabrics mainly composed of tangerine section shaped T/C fibers.

4. After swelling and splitting, the fabric greatly increases in specific surface area; after treatment, the physical adsorption, chemical adsorption and optical properties are greatly improved:

5. The application method involves innovative technology, which can be used for PA6 fiber structure swelling to change fabric style, etc.
