A process for bonding filament with aqueous based polyethylene terephthalate or polyurethane bonding agents via a foam delivery system is disclosed. The process includes the steps of: (a) providing a filament; (b) providing a foam prepared by foaming a solution comprising an agent selected from the group consisting of polyethylene terephthalate or polyurethane bonding agents; (c) applying a foam to said filament; and (d) drying and curing said filament.

Process for making a bonded sewing thread with aqueous based bonding agents via foam delivery system

The invention provides a method of making a copolyester and a resulting copolyester fiber that has increased dyeability and dye retention properties while maintaining good physical properties for textile applications. The fiber may be formed from a mixture comprising terephthalic acid and its ester equivalent in combination with ethylene glycol, and to which is added about 2-4 mole percent of at least two dicarboxylic acids, or their anhydride or ester equivalents excluding terephthalic acid and its ester equivalent, and between about 100 to 700 ppm pentaerytoritol, both being based on the amount of the terephthalic acid and its ester equivalent The dicarboxylic acids and pentaerytliritol may be added before esterification, or after esterification and before polycondensation.

Permanent deep-dye polyester

A process for producing yarn, fiber or filament with substantially improved whiteness, reduced yellowness, reduced abrasiveness, reduced static and softer hand includes melt-blending a masterbatch of zinc sulfide and a polyester with a fiber-forming polyester followed by melt-spinning the blend. The invention additionally provides for polyester yarn, fiber, or filament produced by the process.
