Tex 35 texturized polyester thread. Created specifically for serger and overlock machines.
ProLock is a new texturized polyester thread (DTY) designed for serging on fleece, knits, and stretch fabrics. Available in 73 colors, ProLock is colorfast and can be commercially laundered without risk of fading. With the bulk, elasticity, and flexibility popularized by “woollie-like” nylon threads, ProLock has all these traits plus the addition of higher heat-resistance.
