Document Summary

If one set of yarns oats on the fabric surface, this set protects the other set (satin & twill) If vertical stresses during use are on the protected set of yarns, then protection is good. Floats are good up to a certain length, then bres become vulnerable to plucking and drafting out of the yarn structure. 7/1 satin weaves are susceptible to abrasion damage. Direction of abrasion force relative to yarn oats. Rubbing across a yarn oat is more damaging than rubbing with the yarn length. Cross-wise rubbing creates yarns to roll back and forth- creates stress at points of interlacement. Long oats are more readily snagged by crosswise running than short, regularly interlaced yarns: fibre, yarn, & fabric nishes. Nature of the nish determines its a ect on abrasion resistance. Reduces friction b/w the abrading and textile surface. Finishes when sti en the fabric reduce abrasion resistance. Contribute to development of localized stress, reduce compressive compliance.
