The present invention is related to the use of colored effect pigments for enhancing the infrared absorption capacity of colored polymers and to a method for enhancing the infrared absorption capacity of colored polymers.

Heating of rubber products during processing produces odours which may be abated by commingling the rubber product with fabric softener. The fabric softener may be commingled with the rubber product via a dip tank filled with fabric softener solution, by applying fabric softener to the rubber product prior to heating/processing the rubber product, by injecting the fabric softener into an extruder that is heating/processing the rubber product, and by treating the by-product exiting the side stream of the extruder.

A method of forming a polyethylene terephthalate (PET) mixture with talc includes: providing a feed of PET (PET feed); providing a feed of talc (talc feed); mixing the feed of PET with the feed of talc in a mixer at a PET:talc ratio of about 3:1 to about 1:3 to form a PET/talc mixture; and providing the PET/talc mixture as output. A method of forming a Polyethylene Terephthalate (PET) alloy having talc includes: providing a feed of the PET/talc mixture (PET/talc feed); providing a feed of PET (PET feed); mixing the feed of PET with the feed of PET/talc in a mixer to form a PET alloy having from about 1% (w/w) talc to about 50% talc (w/w); and providing the PET alloy as output.

The thermoplastic polyurethane yarn of the present invention is excellent in abrasion resistance and durability because it contains thermoplastic polyurethane and nanosilica particles having hydrophobic functional groups on the surface thereof and is excellent in durability of a fine denier yarn, and can have a yarn in a form of continuous yarn without breaking yarn development during spinning or stretching. In particular, it is excellent in color dispersibility, antifouling property, scratch resistance, moldability, and the like.
