1. Working principle of Teflon finishing

Teflon finishing The resulting fabric can form a molecular barrier on the surface of the fabric. After being baked at high temperature, it can form a thin film with very small surface tension, which can prevent water and oil contaminants from adhering and penetrating, making them appear like liquid beads on the surface of the fabric. , forming a better water-repellent and oil-repellent effect. At the same time, due to the high-temperature baking during processing, the film formed by the Teflon finishing agent on the fiber surface can be firmly combined with the fiber. At the same time, due to its oil and water repellency, water and oil cannot make this This polymer decomposes, so Teflon-finished fabrics have good washing and dry-cleaning fastness.

2. Product process flow

Sewing → singeing → deboiling → Oxygen bleaching → mercerization → styling → dyeing → washing → Teflon finishing → baking → shrink proofing → inspection

3. Summary of Teflon finishing process

3.1 Fabrics in normal production processes can meet the requirements of three-proof finishing after Teflon finishing; fabrics that have been softened can be finished with Teflon. Although it is slightly effective initially, it will be washed 5 times. Finally, the three defense effects are lost.

3.2 Processed fabrics that require Teflon finishing must have high hygroscopicity, no alkali, clean impurities, and no residual wetting agents. Dyeing auxiliaries, size residues, softeners and other surfactants. During Teflon finishing, the chemical barrel and impregnation rolling tank must be carefully cleaned and operated in accordance with the instructions provided by the supplier.

3.3 Fabrics treated with Teflon can be protected from splashes and damage by water, oil, chemicals and dirt. They are protective and can be used for High-quality outerwear, sportswear, casual wear, protective workwear (such as oil field clothing, military uniforms), tents, travel supplies, rain gear and coatings, etc.
