摘要: A treatment for reducing friction of seat belts which is characterized by containing therein a polyether polyester having an average molecular weight of 2000-15000 which is obtained from a polyether diol and an aliphatic carboxylic acid, and preferably further containing a silicone compound. This treatment can be applied to either seat belt yarns in the yarn-making step or to seat belt webbing. The resulting seat belt is superior in slip properties and retains them even after wear. It is also superior in retractiablity and wear resistance (durability).
