Abstract
Abstract A process of warp sizing polyester filaments and hydrophilic finishing polyester fabrics which comprises (1) coating said polyester with the water-soluble polyester of a dihydric alcohol having two to six carbon atoms and an aromatic polycarboxylic acid compound having three, four or five carboxy groups and (2) drying said polyester onto said filament or (3) curing said polyester onto said fabric.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
110 words
A process of warp sizing textile filaments which comprises the steps of (1) coating said textile filament with an aqueous solution of a water-soluble polyester reaction product consisting essentially of a dihydric alcohol having two to six carbon atoms and an aromatic polycarboxylic acid compound having three, four or five carboxy groups and (2) drying said polyester on said textile filaments, the said alcohol and said acid compound being reacted in a mole ratio where the ratio of acid to alcohol is greater than unity, wherein the acid number of said reaction product is within the range of from 160 to 320 grams of KOH per gram of said product.
Claim 2
Dependent Claim
110 words
A process of warp sizing textile filaments which comprises the steps of (1) coating said textile filament with an aqueous solution of a water-soluble polyester reaction product consisting essentially of a dihydric alcohol having two to six carbon atoms and an aromatic polycarboxylic acid compound having three, four or five carboxy groups and (2) drying said polyester on said textile filaments, the said alcohol and said acid compound being reacted in a mole ratio where the ratio of acid to alcohol is greater than unity, wherein the acid number of said reaction product is within the range of from 160 to 320 grams of KOH per gram of said product.
Claim 3
Dependent Claim
12 words
The process of claim 1 wherein said dihydric alcohol comprises neopentyl glycol.
Claim 4
Dependent Claim
13 words
