What is the production process of polyester interlining?

‌Raw material preparation‌: Use polyester chips and other raw materials, and undergo specific chemical treatment to produce polyester melt suitable for spinning.

‌Spinning‌: Spin the polyester melt into fiber yarn through spinning equipment, involving stretching, cooling, curing and other processes to ensure fiber quality.

‌Post-treatment‌: The spun fibers are post-treated by shaping, oiling, drying and other post-treatments to improve the strength and stability of the fibers.

‌Weaving‌: The treated fibers are woven according to specific warp and weft densities and fabric structures to form grey cloth.

‌Finishing and inspection‌: The grey cloth is repaired, inspected and other finishing work is performed to ensure that the product quality meets the standards.

‌Special function treatment‌ (if applicable): Depending on the needs, special function treatments such as flame retardant and conductive may also be required.

The entire production process requires strict control of process parameters to ensure the final quality and performance of polyester interlining‌
