Abstract
Disclosed are textile lubricants having improved adherency to textile fibers, comprised of a lubricant base oil, an emulsifier and a high molecular weight polymer of one or more alpha-monoolefins having 4 to 20 carbon atoms.
Claims16
A methood of improving the adhesive and cohesive properties of a textile lubricating composition comprised of a base oil selected from the group consisting of mineral oil, fatty esters and natural oils and an emulsifing agent comprising incorporating into the lubricant formulation about 0.01 to 10%, based on the total weight of lubricating composition, of a polymer selected from (a) homopolymers of normal alpha-monoolefins having 6 to 14 carbon atoms and (b) copolymers of two or more normal alpha-monoolefins having 4 to 20 carbon atoms, said polymer having a weight average molecular weight of about 1 to 10 million.
A textile lubricant having improved adhesive and cohesive strengths comprised of 50 to 95 weight percent mineral oil, about 5 to 15 weight percent emulsifier and about 0.01 to 10 weight percent of a polymer selected from (a) homopolymers of normal alpha-monoolefins having 6 to 14 carbon atoms and (b) copolymers of at least two normal alpha-monoolefins having 4 to 20 carbon atoms, said polymer having a weight average molecular weight of about 1 to about 20 million and said percentages being based on the total weight of textile lubricant.
In a method of processing yarn wherein a textile lubricant is applied to the yarn to facilitate processing of the yarn, the improvement comprising processing the yarn with about 0.1 to 10%, based on the weight of yarn of a lubricant comprised of about 50 to 95 weight percent mineral oil, about 2 to 50 weight percent emulsifier and 0.01 to 10 weight percent of a polymer selected from (a) homopolymers of normal alpha-monoolefins having 6 to 14 carbon atoms and copolymers of at least two normal alpha-monoolefins having 4 to 20 carbon atoms, said polymer having a weight average molecular weight of about 1 to about 20 million.
