Abstract
Embodiments of the present invention relate to sizing compositions, glass fibers, and fabrics. For example, some embodiments provide a composition that includes: (a) a cooked starch comprising fluid-swollen starch particles and (b) a film forming polymer. The film forming polymer, in some embodiments, has a glass transition temperature from about −50° C. to about 150° C. The fluid-swollen starch particles, in some embodiments, exhibit a granular swelling power (GSP) from about 1 to about 20.
Claims24
A sizing composition comprising:
- a cooked starch comprising fluid-swollen particles;
- and
- a film forming polymer.
A sizing composition comprising:
- a cooked starch comprising fluid-swollen particles having a granular swelling power (GSP) from about 1 to about 20;
- and
- a film forming polymer having a glass transition temperature from about 0° C. to about 30° C.
A glass fiber strand comprising:
- a sizing composition comprising a film forming polymer, and a cooked starch comprising fluid-swollen particles;
- and
- a plurality of glass fibers in contact with the sizing composition, the plurality of glass fibers having at least one gap formed between two or more of the plurality of glass fibers, wherein the fluid-swollen particles are positioned within the at least one gap.
A glass fiber strand comprising:
- a sizing composition comprising a cooked starch and a film forming polymer;
- and
- a plurality of glass fibers in contact with the sizing composition, wherein the strand exhibits an abrasion broken filament level under 300 broken filaments per pound (BF/lb).
A fabric comprising:
- a plurality of glass strands;
- and
- a sizing composition in contact with the plurality of glass strands, the sizing composition comprising a cooked starch and a film forming polymer, wherein the plurality of glass strands exhibit an abrasion broken filament level under 300 broken filaments per pound (BF/lb).
