Abstract
A dry textile warp size composition for use in the sizing of yarns containing natural fibrous materials, synthetic fibrous materials, or blends of same including a polyester in particulate form, a film former, and optionally a lubricant and other minor additives. The polyester is preferably rendered into particulate form by grinding at reduced temperature, includes anionic hydrophilic groups and is at least substantially saturated. A process for producing the size composition is also disclosed and claimed.
Claims23
A dry textile warp size composition for yarns that contains synthetic or natural fibrous materials comprising a blend of a polyester resin, said resin including ionic hydrophilic groups therein, said resin further being at least substantially saturated, and in particulate form, and a film former, said blend being at least water dispersible and the particulate polyester resin in said blend being at least substantially non-adherent to adjacent polyester resin particles.
A dry textile warp size composition comprising:
- (a) from about 5 to about 90 weight percent of a polyester resin, said polyester including anionic hydrophilic groups thereon, being at least substantially saturated, and being in particulate form;
- (b) from about 5 to about 90 weight percent of a film former;
- (c) an amount of a neutralizing agent necessary to achieve dispersibility in an aqueous medium;
- and
- (d) optionally, a small amount of a defoamer.
A process for producing a textile warp size composition for yarns that contain synthetic or natural fibrous material or blends of same comprising the steps of:
- (a) providing a polyester resin that is at least substantially saturated, said resin having ionic hydrophilic groups thereon;
- (b) rendering said resin particulate in form, said particles being of a size to permit dispersion of same in an aqueous medium;
- and
- (c) mixing a predetermined amount of a film former with said particulate resin adequate to achieve a blend of ingredients in which the resin particles will not agglomerate under normal shipping and storage conditions.
