Japan1. Different proportions. Polyester 1.38, nylon 1.14.
2. Polyester fabric is not easy to wrinkle, and is stiff, good dimensional stability, and good shape retention. Nylon is not good in shape retention, it is not stiff without polyester, and it is easy to deform.
3. The melting point of polyester is 260℃, and the ironing temperature can be 180℃. The heat resistance of nylon is not good enough, the ironing temperature should be controlled below 140℃, and the low temperature resistance is good.
4. Nylon has high strength, good elastic recovery ability, excellent abrasion resistance, moisture absorption and dyeability are better than polyester.
5. Polyester is resistant to sunlight, acid but not alkali. Nylon is alkali-resistant but not acid-resistant, and has poor light resistance. The fiber strength will decrease and the color will turn yellow when exposed to sunlight for a long time.
6. Nylon weaving has a smoother handle and higher surface gloss. The clothing is mostly used in sportswear, swimwear, fitness clothing, and socks.
7. Nylon sewing thread is more expensive than polyester thread, and its tensile strength is also better than polyester sewing thread. Nylon thread can be used where performance requirements are required, such as climbing ropes, parachutes, slings, etc.
8. Twisted nylon material yarn, the produced thread has a certain tensile force, strong tensile force, shiny, high temperature resistance, high speed, mainly suitable for leather sewing, such as: shoe industry, bag industry, Sofa industry, etc. Nylon thread is suitable for ordinary leather sewing thread.
9. The polyester thread has a flat seam, which can meet the needs of a wide range of different sewing industrial products and is widely used. It is produced by unique processing technology and is a special thread for delicate operations such as garment overburden. Polyester sewing thread is also called SP thread. PP thread is a kind of ordinary sewing thread, using 100% polyurethane polyester staple fiber as the raw material, which is flexible, conformable, full color, and good color fastness.
