    • Disclosed are carpet products comprising at least one flexible substrate and at least one coating layer associated with the at least one flexible substrate. The coating layer is formed from an aqueous composition comprising: A) an emulsifier-stabilized vinyl acetate/ethylene (VAE) emulsion copolymer dispersion wherein the VAE copolymer therein comprises co- monomers which include at least vinyl acetate copolymerized with ethylene and optionally also with other additional functional and/or non-functional co-monomers; and B) at least one particulate filler material selected from particulate inorganic compounds and particulate plastic material. The vinyl acetate/ethylene copolymer in the copolymer dispersion has a particle size, d w , ranging from about 50 to about 500 nm as determined by Laser Aerosol Spectroscopy. Such carpet products maintain their integrity and appearance after multiple machine washing operations. Some of these carpet products which have backing coated with certain of the coating compositions used herein also exhibit desirable non-slip properties.

    • Disclosed are carpet products made using certain types of coating compositions to secure carpet fibres to a carpet backing or substrates and/or to secure one or more carpet scrims or other layers to carpet backing. The coating compositions, which can be in the form of either precoating or skip coating compositions, are made from latex binder emulsions based on interpolymers emulsion polymerised from vinyl esters, ethylene, and a multifunctional cross-linking co-monomer such as an unsaturated silane. Such emulsions are also stabilised with surfactant emulsifiers but are substantially free of protective colloid stabilisers. The multifunctional co-monomer alters interpolymer molecular weight, branching and/or flow properties such that films formed from such interpolymers exhibit relatively low elongation values. When the emulsion binder exhibits such non-elongating film-forming characteristics, the carpet coating composition made from such binders can be easily processed without build-up on carpet processing apparatus. Such binder emulsions which are stabilized substantially only with surfactant emulsifiers, and not with protective colloids, also have excellent compatibility with other coating composition components.
    • 公开的是使用某些类型的涂料组合物制成的地毯产品,以将地毯纤维固定到地毯背衬或基底和/或将一个或多个地毯布或其他层固定到地毯背衬上。 涂层组合物可以是预涂层或跳涂层组合物的形式,由基于由乙烯基酯,乙烯和多官能交联共聚单体如不饱和硅烷聚合的互聚物的胶乳粘合剂乳液制成。 这种乳液也用表面活性剂乳化剂稳定,但基本上不含保护胶体稳定剂。 多功能共聚单体改变互聚物分子量,分支和/或流动性质,使得由这种互聚物形成的薄膜表现出相对较低的伸长率值。 当乳液粘合剂显示出这种不延长的成膜特性时,可以容易地加工由这种粘合剂制成的地毯涂料组合物,而不会在地毯加工设备上堆积。 基本上仅用表面活性剂乳化剂而不是用保护胶体稳定的粘合剂乳液也具有与其它涂料组合物组分的优异的相容性。
