What sewing thread does a cowboy wear? Do you have any good brand recommendations?

At present, the production personnel of denim garment factory only know ordinary PP and SP threads, but only in the last two years did they know that there is a kind of high-strength thread and pearlescent thread. PP thread and SP thread are easy to break, especially after washing, high-strength thread will shrink after washing and dyeing, so both of them are replaced. What sewing thread is suitable for denim clothing? The denim market has developed the following two high-quality denim garments:

Qinghongpai cotton-wrapped polyester core-spun yarn: the appearance is the same as that of ordinary cotton yarn. The outside is pure cotton yarn, but the inside is wrapped with polyester filament, so it meets the world environmental protection requirements of low-carbon appearance. Cotton-wrapped polyester core-spun yarn needs to be dyed twice, which is a bit of a test for sewing thread factories. The cored wire produced by Qinghong Wire Industry has been widely used by many Taiwan-funded and Hong Kong-funded enterprises.

Qinghongpai polyester-coated polyester core-spun yarn: There is no difference in appearance from ordinary cotton yarn. The outside is polyester staple fiber and the inside is polyester filament, so the tension is very good, and the shrinkage after high temperature ironing is very small, so it is widely used by foreign denim brands.
