In the textile industry, from fiber production to finished products, from sportswear to home curtains, iSuoChem® additives are used to make fibers easier to spin, fabrics softer to the touch, and colors more vibrant and lasting.
If textiles contain synthetic fibers such as polyester or nylon, antistatic agents play a crucial role in the spinning and weaving process. They prevent static electricity buildup, avoiding fiber repulsion or adhesion to machines, which can lead to breakage.
During melt spinning, antioxidants and UV stabilizers are added to synthetic fibers (such as polypropylene) to protect the polymer from degradation caused by high temperatures and UV radiation.
Preparation and Pretreatment
Fabrics must be cleaned and treated evenly before dyeing.
Wetting agents are used in the scouring process. They help water quickly penetrate the fabric, removing natural waxes, dirt, and spinning oils.
Surface active agents (Surfactants) are key to pretreatment; they act like detergents, removing dirt from the fabric.
pH adjusters are essential for controlling the acidity or alkalinity of the treatment solution, ensuring that enzymes or bleaching agents work optimally.
Defoamers are essential in high-speed jet dyeing machines, preventing foam from causing pump cavitation and uneven processing.
Dyeing and Printing
Transferring color (pigment or dye) onto fabric requires the combined action of various additives.
Dispersants (Dispersing Agents) are crucial for disperse dyes (used on polyester fabrics). They suspend dye particles in water, allowing for uniform transfer to the fabric and preventing clumping.
Thickeners (Thickening Agents) are used in textile printing pastes. They give the paste the appropriate viscosity, allowing it to maintain a clear pattern without bleeding into the surrounding fabric.
Enhancing Added Value
In an increasingly competitive textile and apparel market, increasing the added value of textile products is essential for expanding market share.
Soft-touch PU powder can be used as a coating or finishing agent, giving fabrics a luxurious, soft feel, such as peach skin or suede.
Slip agents can be used to improve fabric surfaces, making them smoother to the touch or reducing snagging.
Flame-retardant finishing agents are used in decorative fabrics, curtains, and protective clothing to meet fire safety standards.
Antistatic agents, used as a final finishing agent for carpets and synthetic fiber clothing, prevent annoying static electricity and dust accumulation.
Adhesion promoters are used in fabric coating treatments (e.g., applying a PU leather coating to a base fabric) to ensure the coating does not peel off.

Q2 How do I get a "soft skin" feel on my printed fabric?
Adding APU10-80 Soft-touch PU powder to your textile coating creates a soft, velvet-like texture.
Q3 Are these textile additives safe for clothing?
iSuoChem chemical fabric additives are designed to meet global safety standards like REACH and RoHS, ensuring they are safe for consumers.
Q4 When producing polyester filament at high speed, we experience a high breakage rate and a lot of static electricity in the workshop. What could be the cause?
This is usually because the fiber does not conduct electricity well. Man-made fibers (such as polyester and nylon) easily create static electricity during high-speed rubbing. When static builds up, the fiber strands push each other away or get stuck on the machine rollers, which causes breakage. Adding a good antistatic agent is the key to solving this. We suggest adding an internal antistatic agent into the spinning oil or directly into the fiber. This lowers the fiber's surface resistance and quickly removes static electricity, which greatly reduces the breakage rate and improves production.
Q5 Polypropylene (PP) turns yellow and becomes brittle during spinning. How can we improve this?
The molecular chains of polypropylene break down easily when they are hot and melted, which causes yellowing and loss of strength. You need to add antioxidants during the spinning step. For products that will be used outside in the sun for a long time, you should also add a UV stabilizer. This protects the fiber from sun damage later on and stops it from turning into powder or losing strength.
Q6 During pre-treatment washing, we noticed that the fabric gets wet very slowly, which later causes uneven bleaching. What can we do?
This happens because natural fibers (like cotton) have natural oils and waxes on them that repel water. You need to add a strong wetting agent to the washing liquid. This lowers the surface tension of water, so the liquid can quickly get inside the fiber and clean out the impurities. This gives you a good base for even dyeing later.
Q7 We want to add a flame-retardant coating to our sofa fabric, but after treatment the fabric feels very hard and stiff, and the coating flakes off. Is there a way to get both fire safety and a nice feel?
This is about balancing how the fabric feels with how well it works, plus making sure the coating stays on.
Feel problem: You can pick a flame retardant that is better for the environment, with smaller particles that mix well with the resin. Or you can add some soft-touch PU powder to the mix. This gives flame protection while also making the fabric much softer and fuller.
Sticking problem: When the coating peels off, it usually means it is not sticking well enough to the fabric. We suggest adding a little adhesion promoter to the coating mix. This makes the bond between the coating and the fiber much stronger, so the coating can handle washing and rubbing without coming off.
