Abstract
A finishing size composition and method of making and using same as a finishing size to control the dimensional stability of woven fabric in which a paste comprising a noncongealing, hydrophillic, starch ether or ester or combinations thereof exhibiting five gram alkali fluidity from about 10 millimeters to about 97 millimeters is padded to fabric at a temperature of less than 140.degree. F. after which the padded fabric is dried and has an add-on weight increase of from about 0.5-4.5%.
Claims8
A method of preparing a finished size fabric said method comprising:
- (a) preparing a slurry comprising a noncongealing hydrophilic starch exhibiting a five gram alkali fluidity of from about 10 milliliters to about 97 milliliters and a solvent;
- (b) heating the slurry to at least 165.degree. F. to form a finishing size paste;
- (c) cooling the finishing size paste of step (b) to at least 140.degree. F.;
- (d) padding a fabric with the finishing size paste of step (c);
- (e) removing excess finishing size paste from the contacted fabric, and
- (f) drying the contated fabric.
A fabric having a padded finishing size comprising 2-hydroxyethyl ether modified starch exhibiting a 10 gram alkali fluidity of from about 58 milliliters to about 64 milliliters.
