摘要:
The invention provides a sizing composition based on water-soluble polymers, intended for sizing warps of textile yarns and a process for obtaining such compositions and for the sizing of textile yarns. More particularly, provided are compositions comprising, 40 to 90% by weight of a polyester-urethane and 10 to 60% by weight of an acrylic and/or vinyl polymer especially suitable for sizing polyester yarns such as polyethylene terephthalate.
