Floor covering with universal backing and methods of making and recycling

A dimensionally stable floor covering, comprising a tufted textile substrate and a reinforcement layer wherein vacuum is used to move adhesive into stitch portions of the yarns and into the back side of the primary backing substrate to provide increased dimensional stability for the entire floor covering. Mixing of reinforcement fibers and adhesive takes place before in situ filtration of the adhesive and fibers. Further, compressed air is injected into the adhesive/fiber composition to provide spaces between the fibers before application of pressure to the composition. The vacuum, mixing, and injection of compressed air assist in preparing the adhesive and fiber composition to be in the preferred condition and position before the application of pressure to the composition.

FLOOR COVERING WITH UNIVERSAL BACKING AND METHODS OF MAKING AND RECYCLING

A dimensionally stable universal floor covering includes a tufted textile substrate and a reinforcement layer to provide dimensional stability for the entire floor covering. Vacuum, mixing, and injection of compressed air assists in preparing an adhesive and fiber composition to be in the preferred condition and position before the application of pressure to form the reinforcement layer. The universal floor covering is selectively cut and transported in a roll for installation, and it can be conveniently recycled if necessary.

METHOD FOR MANUFACTURING A CARPET OR A RUG AND A CARPET OR RUG OBTAINED THEREBY

Method for manufacturing a carpet or a rug, comprising the following steps: the step (S1-S2) of providing a primary backing (1), being a woven or non-woven layer comprising filaments (2) of polyethyleneterephthalate and copolymer of polyethyleneterephthalate, the coPET having a lower melting temperature than the PET and wherein said PET is available in said primary backing (1) in a higher amount than said coPET; the step of providing a glue layer (11) consisting for 50% or more out of coPET; the step of tufting yarn at least into said primary backing (1); the step of activating said glue layer (11) at least for partially fixing said yarn (12) on said primary backing (1).

The invention also concerns carpets (16) and rugs that are obtained or obtainable by means of such method.

DUAL LAYER WET LAID NONWOVEN MAT

A carpet tile, includes a pile fabric layer, a primary backing coupled with the pile fabric layer, a secondary backing coupled with the primary backing, and a nonwoven mat. The nonwoven mat includes a glass fiber rich layer having at least 80 weight percent of the glass fibers and a synthetic fiber rich layer having at least 80 weight percent of the synthetic fibers. The nonwoven mat also includes an emulsion binder that is applied to the glass fiber rich layer and the synthetic fiber rich layer to bind the glass fibers and synthetic fibers in said layers together. The nonwoven mat includes at least 10 weight percent of the binder and the binder is curable at a maximum temperature of below 330 degrees Fahrenheit. A total weight percent of glass fibers in the glass fiber rich layer and the synthetic fiber rich layer is at least 48 percent.

Spunbonded nonwoven fabric and tile carpet using the same

The present disclosure relates to a spunbond nonwoven fabric for a base fabric for tile carpet which not only has excellent spinnability during the production of nonwoven fabric and improves tensile strength and tensile elongation, and has the effect of recycling waste such as polyester plastic, by using recycled polyester with optimized intrinsic viscosity, crystallization temperature, and number of foreign matters as a raw material, and a tile carpet using the same.
