Abstract
Abstract In the sizing of textile yarns with a chlorinated solvent solution of a low crystallinity chlorinated polyolefin, undesirable tackiness of the resin size is avoided by combining the chlorinated resin with a minor proportion of a high molecular weight aromatic hydrocarbon polymer such as polystyrene. The sizing resin mixture can be recovered for reuse from a solvent desizing process.

Claim 1
Independent Claim
56 words
In a resin composition for sizing textile yarns, the improvement wherein said resin composition is a mixture of a chlorinated polyolefin having a crystallinity of less than about 10 percent and about 10-50 percent based on the weight of chlorinated polyolefin of an aromatic hydrocarbon polymer having an average molecular weight of at least about 100,000.
Claim 2
Dependent Claim
56 words
In a resin composition for sizing textile yarns, the improvement wherein said resin composition is a mixture of a chlorinated polyolefin having a crystallinity of less than about 10 percent and about 10-50 percent based on the weight of chlorinated polyolefin of an aromatic hydrocarbon polymer having an average molecular weight of at least about 100,000.
Claim 3
Dependent Claim
12 words
The composition of claim 1 wherein the aromatic hydrocarbon polymer is polystyrene.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
18 words
The composition of claim 2 wherein the chlorinated polyolefin is a copolymer of vinyl chloride and vinylidene chloride.
Claim 6
Dependent Claim
30 words
In the process for sizing a textile material with a chlorinated lower aliphatic hydrocarbon solvent solution of a resin, the improvement wherein said resin is the mixture of claim 1.
Claim 7
Dependent Claim
