Floor coverings having a greige good, an adhesive layer, and a secondary backing material. The greige good has a primary backing component having adjoined first and second portions, and a plurality of fibers. The secondary backing material has an attached portion and a first exposable portion, with the attached portion adhered to the first portion of the primary backing component by contact with the adhesive layer. The second portion of the primary backing component is unattached to the first exposable portion of the secondary backing material, and the first exposable portion defines a portion of the first end edge of the floor covering. The second portion of the primary backing component is selectively moveable relative to the first portion to a position in which at least a portion of the second portion of the primary backing component does not overlie the first exposable portion of the secondary backing material.

The invention relates to a fabric. The fabric (10) comprises, in the fabric material, threads (11a1,12a1;13a1,14a1) of a material conducting electricity well, by means of which electro-magnetic radiation and magnetic fields are filtered. The threads (11a1,12a1;13a1,14a1) are placed next to each other. Furthermore, the threads are wound around their winding axes (X1,X2;Y1,Y2) so that the first thread (11a1, 13a1) in the fabric is wound clockwise, and the second thread (12a1, 14a1) next to it is wound counterclockwise.

An acoustic absorption and concealing device including at least one vertical strip including at least three structural layers, a central layer made of an acoustic absorbent material, and two external layers made of a knitted transonic material, applied on either side of the central layer, where the two external layers are made from flame-retardant polyester fibre threads and the central layer is made from polyester. The acoustic absorption and concealing device makes it possible to obtain a blind, or a partition panel of reduced thickness less than 7 mm having a low reaction to fire and optimal features of acoustic absorption, concealing and thermal reflections.

This application is directed to polymer blends of polyethylene naphthalate, polytrimethylene terephthalate, and polyethylene naphthalate, for use in fibers, such as carpet fibers, and other applications. This application is also directed to methods of producing such polymer blends and fibers.

A method for manufacturing bulked continuous carpet filament, the method comprising: (1) reducing a chamber pressure within a chamber to below about 5 millibars; (2) after reducing the chamber pressure to below about 5 millibars, providing a polymer melt to the chamber; (3) separating the polymer melt into at least eight streams; (4) while the at least eight streams of the polymer melt are within the chamber, exposing the at least eight streams of the polymer melt to the chamber pressure of below about 5 millibars; (5) after exposing the at least eight streams of the polymer melt to the chamber pressure of below about 5 millibars, recombining the at least eight streams into a single polymer stream; and (6) forming polymer from the single polymer stream into bulked continuous carpet filament.

A composite spacer fabric comprises an outer flat warp-knitted fabric layer having openings each formed by a respective plurality of stitches and an inner flat warp-knitted fabric layer also having openings that are each formed by a respective plurality of stitches. The second warp-knitted fabric layer further has at least a first and a second yarn system. The yarns of the first yarn system run in a production direction on exactly one respective stitch wale and the yarns of the second yarn system extend over at least two adjacent stitch wales that run in the production direction. Spacer yarns interconnect the warp-knitted fabric layers.

Disclosed is an improved non-woven primary backing material suitable for use in the manufacture of textile carpet compositions. Also disclosed is a method for making the disclosed primary backing components and a method for making carpets comprising same.

The invention pertains to a method to manufacture a textile product comprising a first sheet having polymer yarns fastened to this sheet to form a pile thereon, the method comprising providing the sheet, stitching the polymer yarns through the sheet to form the pile on a first surface of the sheet and loops of the yarns at a second surface of the sheet, heating the second surface of the sheet to at least partly melt the loops of the yarns to fasten the yarns to the sheet, wherein the method comprises measuring a roughness of the second surface with the at least partly molten loops of the yarns thereon, after the at least partly molten loops have solidified and, if the roughness differs from a predetermined surface roughness, adapting the method to manufacture the textile product, in order to obtain a second surface roughness that differs from the measured surface roughness. The invention also pertains to a device for applying this method.

A method of manufacturing bulked continuous carpet filament from recycled polymer. In various embodiments, the method includes: (1) reducing recycled polymer material into polymer flakes; (2) cleansing the polymer flakes; (3) melting the flakes into a polymer melt; (4) removing water and contaminants from the polymer melt by dividing the polymer melt into a plurality of polymer streams and exposing those streams to pressures below 25 millibars or another predetermined pressure; (5) recombining the streams; and (6) using the resulting purified polymer to produce bulked continuous carpet filament.

A tufting machine (1) and method for operating a tufting machine operating a needle selection mechanism based on pattern data by selecting a needle (10) with yarn (4) required for the pattern such that the selected needle is driven by a needle bar (11) through the backing medium (7), to form a tuft while a needle that is not required for the pattern is not selected by the needle selection mechanism. Yarn is fed via a yarn feed mechanism (2) comprising a plurality of actively driven yarn drives each driving a respective yarn to a respective needle, the yarn drives being at a location between a yarn creel and the needle. The method being characterised by operating the yarn feed mechanism (2) to deliver at least 70% of the yarn required for a tuft as the needle (11) moves from top dead centre to bottom dead centre.
