example 1

[0123]Ultramid Balance® biobased nylon 6,10 resin available from BASF was dried, melt spun, drawn and air-jet textured to produce bulked continuous filament yarns of 1000 denier containing 60 filaments of tri-lobe cross-section. Four coloured yarns were produced via the addition during the melt spinning stage of formulated masterbatches containing various pigments. The four colours were dark brown (“Raisin”), light grey (“Hawk Grey”), medium grey (“Elephant”) and dark grey (“Seal”). The spin speed was 1100 m / min with a draw ratio of about 2.7:1. Finish oil was applied to the yarn during the spinning stage to give about 0.45% wt finish on yarn. The tenacities and elongations to break of the four yarns produced were as follows:

example 2

[0124]A yarn comprising 90% wt of the 6,10 resin used in Example 1 and 10% of a nylon 6,6 resin with a sulfuric acid relative solution viscosity of 3.1 was produced using a similar process to Example 1. The nylon 6,10 and the nylon 6,6 were melt blended during the melt spinning stage. The bulked continuous yarn produced had a denier of 600 and consisted of 30 filaments of a tri-lobe cross-section.

example 3

[0125]Carpet Tiles were prepared using the yarns prepared in Example 1 and 2. The resulting carpet tiles were found to pass the following property tests: Colourfastness, Tuflock, Lisson, Castor Chair, Dimensional Stability, Hexapod and Critical Heat Flux.

Abstract

There is disclosed herein various floor coverings and methods for making the same. In one embodiment, there is disclosed a floor covering including a primary backing layer having a fibrous face and an underside, wherein the fibrous face is formed from a bulked continuous filament yam comprising a plurality of continuous filaments formed from a biobased polyhexamethylene sebacamide polymer or a blend of a biobased polyhexamethylene sebacamide polymer together with up to 80 wt % of at least one other polymer compatible with the biobased polyhexamethylene sebacamide polymer. There is also described a method of making a floor covering comprising: tufting or implanting a bulked continuous filament yarn into a primary backing material, wherein the yam comprises a plurality of continuous filaments formed from a multi-component fibre comprising a biobased polyhexamethylene sebacamide polymer or a blend of a biobased polyhexamethylene sebacamide polymer together with up to 80 wt % of at least one other polymer compatible with the biobased polyhexamethylene sebacamide polymer.

Description

TECHNICAL FIELD[0001]The present invention relates to a laminated floor covering such as a carpet or carpet tile and to a method for making the laminated floor covering.BACKGROUND OF THE INVENTION[0002]Carpets, such as free-lay carpet or backed carpet tiles are typically prepared as either a tufted or a fusion bonded carpet material having a wear fibrous or pile surface from which pile yarns upwardly project. Carpet tiles differ from the production of ordinary tufted or other fibrous-faced carpets because there is no requirement on a typical carpet for a heavy backing layer. In a carpet tile, a rigid stabilized mass of a thermoplastic backing layer is required in order to hold down the carpet tile so that it can function as a free-lay carpet tile. Generally, the backing layer has a high filler content (e.g., limestone) and is employed with various scrim materials such as glass fibres, polyester or a combinations thereof, to impart dimensional stability. Generally the thermoplastic b...
