Antistatic Treatment Of Polyester Non-woven Fabric

1. The performance of static electricity in life
The static electricity in the air is everywhere, running on the machine, on the clothes, and more on the fabrics being processed and finishing the textiles, causing the fabrics to be adsorbed on the setting machine and unable to fall down, and the rolling and dropping of the cloth become inoperable. , Especially polyester fabrics, because of poor water absorption, static electricity is more likely to stick there and not go. How can we make static electricity go faster and return efficiency? The fast electrical conductivity of the antistatic agent PK has a short half-life for an electrostatic charge, which is reduced from the 60S to <1S, which can quickly export the static electricity generated by the friction of the polyester fabric surface on the machine and restore its lovely appearance.
Polyester cloth is definitely a mixed bag. As far as the advantages are concerned, it is washable, wrinkle-resistant, and shape-retaining; as far as the disadvantages are concerned, it has poor hygroscopicity, is prone to static electricity, and is easy to stick to dust. We will sort out its shortcomings while maintaining its advantages, and it will be perfect. The polyester fabric on the setting machine rubs on the high-speed rotating cloth roll, and static electricity becomes even more unscrupulous. The appearance of the antistatic agent PK reduces the half-life of static charge from the 60S to <1S and quickly leads out the static electricity generated by the friction of the surface of the polyester fabric on the machine.
There is no best in this world, only the right is perfect. Use the antistatic agent PK to solve the static electricity of the polyester cloth, and eliminate the static electricity on the setting machine by analogy. It changes the defects of the polyester fabric that it is easy to be electrostatically charged and easy to stick to dust. It also gives it more usable places. The anti-wrinkle and shape-retaining application areas add a strong touch of color. With the help of PK finishing, polyester fabrics are no longer the favored object of static electricity. In the textile world, it can better serve people. Isn't this a fortunate thing?
2. Take polyester antistatic finishing as an example:
Different application processes
Dipping method: antistatic agent 1.0-2.0% (o.w.f.); bath ratio 1:10, room temperature immersion for 15-20min→dehydration→drying→sizing (190℃*30sec)
Padding method: antistatic agent 15-30g/L; padding working fluid (rolling residual rate 70-80%) → drying → shaping (190℃*30sec)
It is used for the antistatic finishing of polyester, acrylic, nylon, vinylon, and other synthetic-fiber fabrics. The treated fiber surface has good moisture absorption and conductivity and has little effect on color light and colorfastness.
