WATER-BASED SURFACE TREATMENT AGENT

A surface treatment agent which is an aqueous emulsion containing: (a) a fluorine-free polymer including: (i) repeating units derived from a long-chain (meth)acrylate ester monomer represented by the formula: CH.sub.2═CA.sup.11-C(═O)—O-A.sup.12, wherein A.sup.11 is a hydrogen atom or a methyl group, and A.sup.12 is a linear or branched aliphatic hydrocarbon group having 10-30 carbon atoms; (b) a surface active agent including both of a nonionic surface active agent and an anionic surface active agent, wherein the amount of the anionic surface active agent is at least 22% by weight, based on the total of the nonionic surface active agent and the anionic surface active agent; and (c) a liquid medium comprising water.

A CARPET, A CARPET PILE YARN, AND A METHOD FOR PRODUCING THE SAME

A carpet comprising a backing and pile comprising looped or cut tufts of pile yarn attached to and extending from the backing. The pile yarn comprises un-twisted, entangled filaments. The filaments are self-crimped and optionally textured multi-component filaments. A first component of the multi-component filament comprises a first thermoplastic polymer and a second component of the multi-component filaments comprises a second thermoplastic polymer. The first and the second thermoplastic polymer have different yield behavior, whereby the multi-component filaments are self-crimping.

Low density attached polyurethane foams made using a combination of frothing and blowing methods
09765477 · 2017-09-19 · ·

Textiles backed with a polyurethane cushion are produced by applying a layer of frothed polyurethane-forming mixture to a surface of the textile. The mixture contains both water and a physical blowing agent. The layer expands due to the action of the water and the physical blowing agent and cures to form an attached cushion having a density of 176 g/L or less.
