Sewing Thread for Industrial Textile
Filmedia® supply different kinds of sewing threads for industrial textile, mainly includes, Aramid Sewing Thread, Fiberglass Sewing Thread, PTFE Sewing Thread, PTFE coated Sewing Thread and so on. They are all of excellent performance such as not easy aging, high tensile strength, convenient for sewing etc.
Polyester Sewing Thread
It’s one of the most widely used industrial sewing threads. It’s strong, abrasion-resistant, and resistant to sunlight and chemical degradation. Recycled polyester sewing thread is a versatile, green choice, often used in clothing, bedding, filters, awnings, patio furniture, upholstery, and other applications.

Aramid Sewing Thread
Aramid fiber is famous for its high strength – to – weight ratio, which is 5 times stronger than steel on an equal weight basis. Aramid fiber sewing thread has extremely high tensile strength, heat resistance, and abrasion resistance. It is often used in the sewing of high – temperature – resistant fabrics, such as fire – resistant clothing, aerospace – related textiles, and some high – strength industrial products.

Fiberglass Sewing Thread
Fiberglass sewing thread is a durable and heat-resistant thread made from fiberglass fibers. It is commonly used in industries where high heat resistance, strength, and durability are needed, such as in the automotive, aerospace, and industrial sectors. The thread is often coated with a layer of silicone or other materials to enhance its heat resistance and smoothness for sewing.

UHMWPE Sewing Thread
Ultra-high molecular weight polyethylene (UHMWPE) sewing thread is a high-performance sewing material that is leading the development of modern textile manufacturing, and its irreplaceable importance is becoming increasingly evident. As one of the three major high-performance fibers currently available, it offers excellent properties such as high strength, high modulus, low density, abrasion resistance, acid and alkali resistance, and UV resistance.
