Abstract:
1. A tire cord comprising a yarn, said yarn having a spin finish composition thereon, said spin finish composition comprising at least about 10 percent by weight based on said spin finish composition of components (a) and (b) having the formula wherein each of said R 1 and said R 3 is selected from the group consisting of hydrogen or an alkyl group having from one to 22 carbon atoms or an alkylene hydroxy group having from one to 22 carbon atoms, said x is zero or one, said R said y is zero, or from one to 25, and said z is zero or one, in said component (a), said x and z are equal to zero and the average molecular weight of said component (a) is less than or equal to 1,900 and if R in said component (b), at least one of said x or said z is equal to one or said component (b) is a complex polyoxyethylene glyceride-containing compound having greater than 10 polyoxyethylene units; up to about five percent by weight based on said spin finish composition of component (c) of an ethoxylated silicone; and at least about one percent by weight based on said spin finish composition of component (d) having the formula wherein R 4 is —C— or —COC—; a is 0 or 1; R 5 is —H; from —CH 3 to —C 18 H 37 ; or —CH(R 6 )—CH 2 O); b is 4 or 6; and R 6 is —H or —CH 3 or —H and —CH 3 in a ratio of 10:90 to 90:10.
