Abstract:
A discrete superabsorbent layer is adhered to the lower surface of a fibrous absorbent structure using a water-based polymeric binder is disclosed. The advantages are that a superabsorbent roll good can be prepared for later conversion into disposable absorbent products. The use of the water-based polymeric binder prevents particles of superabsorbent from becoming dislodged from the structure during handling and processing.
Abstract:
A floor covering article comprises a decorative fabric layer, pile yarns forming a decorative pile surface projecting from and partially covering the upper surface of the decorative fabric layer, and means for securing the pile yarns to the decorative fabric layer. The decorative pile surface covers between about 5% to about 95% of the upper surface of the decorative fabric layer so that the decorative fabric is clearly visible when the floor covering article is in planar orientation. The overall effect of the floor covering article, including the decorative fabric and the decorative pile surface, is decorative.
Abstract:
A lightweight, high-strength composite fabric suitable for use in carpet backing, roofing and membranes and other products which employ rugged fabrics. The composite fabric comprises a layer of nonwoven material disposed between a layer of low shrinkage warp strands and a layer of low shrinkage weft strands. The layers are stitched or knitted together and the resultant fabric may be coated with a resin or sizing to prevent slippage between the several layers of the fabric and impart a measure of stiffness to the fabric. The fabric may be manufactured in sheet or, more preferably, roll form and may be coated with materials suitable for desired end applications, e.g., bituminous material whereby the fabric may function as a ready-to-use roofing membrane or other high-strength fabric product.
Abstract:
A nonwoven primary carpet backing includes thermoplastic polymer filaments or fibers bonded by means of a binder polymer. The backing includes at least a distinguishable thermoplastic woven layer, a distinguishable thermoplastic continuous layer, or a distinguishable nonwoven layer including filaments or fibers bonded by means of a binder polymer, which layer reduces the delamination strength of the backing, measured in accordance with DIN 54310, by at least 30% and preferably by at least 50%, with respect to the same backing without the distinguishable layer. Although the breaking strength of the untufted backing according to the invention is lower than that of untufted backings not including the distinguishable layer, the tufted backing according to the invention actually has a higher breaking strength and elongation than tufted backings not including the distinguishable layer.
Abstract:
A carpet product comprises a backing material and a face yarn, wherein the face yarn comprises synthetic carpet fibers and synthetic fibers having high moisture transport properties. Preferred face yarns are composed of a combination yarn comprising the synthetic carpet fibers commingled with the synthetic fibers having moisture transport properties. The carpet products have a texture and feel approximating that of conventional synthetic fiber facings, yet effectively transport moisture so that the carpets feel drier upon exposure to moisture.
Abstract:
A carpet having a pile layer, a support layer and a rear coating. The carpet has an intermediate layer formed from a mat comprising fibrous parts made predominantly of plastic which are in part thermoplastic and of low-melting point fibers and in part higher-melting point fibers, and melted regions providing coherence of both of the fibers, the melted regions being formed of partly melted regions of the low-melt-ing point thermoplastic fibers.
Abstract:
A lightweight dust control mat having enhanced resistance to oxidation and ozonation is provided. The mat includes a rubber backing sheet with a base rubber of NBR or SBR mixed with a polar polymer additive and a chemical blowing agent. The ratio of the base rubber to the polymer additive is between about 1.2 and 9. Following vulcanization, the rubber sheet has a specific gravity of less than about 0.98 and a Bayer ozone cracking incidence factor of 4 or less.
Abstract:
A carpet having pile which is made up of fibers adhered to each other at points along their lengths with a chemically activated adhesive, as well as a process for treating a carpet, are disclosed. The carpet of the present invention is characterized by improved initial appearance and superior wear resistance when compared to prior art carpet constructions.
Abstract:
A tufted carpet comprises consecutively a primary backing stitched with loops of yarn to form a tufted structure projecting outwardly from the primary backing, a layer of latex, a layer of polyolefin, and a secondary backing comprising a woven polyolefin.
Abstract:
An improved cushioned carpet fabric is provided. The cushioned carpet comprises a primary carpet having a primary base and a plurality of pile-forming yarns projecting outwardly from one side. A layer of reinforcement material is bonded to the primary base on the side opposite the pile forming yarns. The reinforcement layer is adjacent to and embedded in, a cushion layer of a polymer such as a polyurethane. There is preferably no additional adhesive between the cushion layer and the layer of reinforcement material since the primary carpet fabric is mated in-situ to the polyurethane-forming composition without preheating the polyurethane-forming composition. An apparatus and process for forming the cushioned carpet fabric of the present invention are also provided.
