摘要： in which R1 and R2 are the same or different lower alkylene units such as ethylene, propylene and so forth up to 5 carbon atoms, R is an alkyl group containing 5 to 17 carbon atoms, and n has a value to produce a molecular weight of at least about 300. Preferably, the yarn is thereafter heated for 10 to 160 seconds at a temperature of from about 215* to 230*C. The yarn is particularly useful in the production of tire cord.
An improved polyester yarn is prepared by applying to the yarn a finish composition consisting essentially of a polyalkylene glycol compound having the formula摘要翻译： 通过向纱线施加整理剂组合物来制备改进的聚酯纱线，该整理剂组合物基本上由具有式ORA PARALLEL RC-（O-R1-O-R2）n-OH的聚亚烷基二醇化合物组成，其中R 1和R 2相同或不同 低级亚烷基单元如乙烯，丙烯等至多5个碳原子，R是含有5至17个碳原子的烷基，n具有至少约300的分子量的值。优选地，纱线是 然后在约215℃至230℃的温度下加热10至160秒。纱线特别可用于生产轮胎帘线。

摘要： An improved polyamide yarn is prepared by first applying to the yarn an aqueous emulsion of an oxidized polyethylene wax having an average molecular weight between about 1,000 and about 3,000, and containing between about 3 percent and about 9 percent oxygen by weight, thereafter heating said yarn to a temperature between about 100*C. and about 175*C., and then applying to said yarn a composition comprising an aqueous dispersion of colloidal silica and a polyethylene glycol ester of a C6 to C18 aliphatic acid, said polyethylene glycol having a molecular weight of about 200 to 600. The yarn is particularly useful for industrial purposes such as braided hose, rope belts, etc.
