    摘要： Described are methods of making a carpet by (a) providing a primary backing material having a front side and a back side, (b) tufting a yarn into the primary backing material to produce a carpet pile on the front side of the primary backing material and loops of the yarn on the back side of the primary backing material, (c) applying by slot coating a layer of a first melted coating composition onto the back side of the tufted primary backing material, (d) applying by slot coating a layer of a second melted coating composition onto the coating applied in step (c) thereby fixing the loops of the yarn to the primary backing material, and (e) applying and pressing a secondary backing onto the slot coated tackifying resin layers and pressing it to join the first and second tackifying resins and the primary backing and secondary backing and yarn loops together to form a carpet.

    摘要： By utilizing recovered polyvinyl butyral (30) in the production of carpet backcoatings (34), the amount of waste polyvinyl butyral that is landfilled or otherwise disposed of is significantly reduced, as is the need for manufacturing polyvinyl butyral. The recovered polyvinyl butyral (30) is size reduced (32) and then utilized by itself or with other ingredients (33, 36) to provide a composite used in the manufacture of a useful product (35, 37) (like carpet backing), and then the composite material is used to make the useful product (35, 37) (such as carpet backing (34), which is used as a primary or secondary backcoating (34) in the manufacture of new carpeting (35) or as a precoat, main back coat or combination precoat/main back coat (34) in the manufacture of new carpet tile (35) In addition, waste carpet (20) may optionally be used with the recovered polyvinyl butyral as a filler material (24); thus, further reducing the amount of waste that is landfilled or incinerated.

    摘要： This invention relates to a carpet backing latex composition comprising an emulsified polymer, non-cellulosic fibers or a mixture of non-cellulosic fibers and cellulosic fibers, and an effective amount of at least one dispersant for the fibers. Within the scope of the invention is a process for making a carpet backing latex composition comprising adding a dispersant to a carpet backing latex and then adding non-cellulosic fibers or a mixture of non-cellulosic fibers and cellulosic fibers to the latex with slow agitation. Carpet produced with this fiber-containing latex composition is characterized by improved physical properties such as tuft bind.
