Will the pre-treatment conditions of nylon fabric affect the level dyeing properties of nylon?

The improper selection of conditions for the pretreatment of nylon fabric is also an important factor that causes uneven dyeing.

Improper fabric pretreatment mainly includes: uneven fabric treatment, which makes the absorption performance of the fiber greatly different, causing dyeing and blooming; the rapid rise in the pretreatment process of the jig dyeing machine causes the nylon yarn to shrink suddenly, or the temperature during heat setting Non-uniformity will cause structural differences in nylon fibers, and uneven dyeing will occur during the dyeing process.
