(H.sup.10.fwdarw.170 C.), the heat of fusion being measured by Differential Scanning calorimetry. The invention further relates to a carpet comprising a carpet backing layer obtained from the carpet backing layer composition and a method for the preparation of the carpet.

The present invention pertains to a method for manufacturing a laminated textile product comprising providing a first intermediate product comprising a primary backing having a front surface and a back surface, and yarns stitched into the primary backing, the yarns extending from the front surface of the backing material, feeding the intermediate product along a body having a heated surface, the back surface being pressed against the said heated surface, to at least partly melt the yarns present in the intermediate product to bond the yarns to the backing, wherein the part of the back surface that is pressed against the heated surface has a relative speed with respect to the heated surface, so as to provide a second intermediate product having a calendered back surface, providing a dimensionally stable carrier sheet or secondary backing, and connecting the second intermediate product to the carrier sheet by providing a hot melt adhesive between the calendered surface and the sheet, and pressing the sheet to the second intermediate product to form the textile product.

In a method for the application of an elastomer to both sides of a fabric layer, the fabric layer is placed onto a resilient support and the elastomer is applied to the fabric layer in a flowable state under pressure exclusively from one side and the resilient support is compressed during the application of the elastomer by the pressure of the elastomer.

Disclosed is a shingle that uses a polyester sheet as a substrate layer. The polyester sheet has a sufficient weight and is needled and formed from two layers to resist shrinking upon cooling after the heated asphalt layers are applied to the polyester substrate sheet 102. In addition, additives may be included in the asphalt to lower the softening point temperature of the asphalt that further reduces shrinking of the polyester substrate 102 or allows other polymers that are more fire retardant to be used. Fire retardants can be placed in the polyester sheet fibers, placed in the bonding agent for the polyester fibers, or the polyester sheet can be coated with the fire retardant. Alternatively, or in addition to treating the polyester sheet 102 with fire retardant, fire retardant materials such as ammonium sulfate can be added to the liquid asphalt prior to application of the asphalt layers.

The invention features a thermoplastic film comprising greater than 70% by weight of a styrene block copolymer having an unsaturated mid block, diblock content of no greater than about 10% by weight and a MFR of from about 15 to about 200 ASTM D 1238 (190 C., 2.16-kg). The thermoplastic film can be used to form elastic composites that are useful in disposable articles (e.g. disposable absorbent articles).

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.

Disclosed is a fiber laminated structure that has a waterproof breathable function, has stable waterproofness even when being stretched, has high peel strength, and is superior in durability. Some instances provide a water-repellent fiber laminated structure in which a nonwoven fabric web with a bulkiness of 1.5 to 2.5 cm3/g and a thickness of 20 to 60 ?m including a fiber made of a polyurethane-based polymer having a fiber diameter of less than 1 ?m is present on one side of a woven cloth having stretchability at least in either a warp direction or a weft direction with an adhesive agent A interposed therebetween.

The present invention pertains to carpet and carpet tile. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one non-chlorinated, non-polyvinyl butyral thermoplastic polymer or composition having a specific growth tension at 40 C and a specific residual stress at 25% strain. Additional steps and procedures include washing or scouring the primary backing and fibers prior to the extrusion step, and utilizing implosion agents. The preferred olefin block copolymer are ethylene based block interpolymers. The constructions and methods described herein are particularly suited for making tufted, broad-loom carpet having improved abrasion resistance.

The present invention relates to a packaged hot-melt pressure sensitive adhesive comprising a hot-melt pressure sensitive adhesive composition and a coextrusion coating consisting of neat low density polyethylene, neat polypropylene, or neat ethylene vinyl acetate. The present invention further relates to the use of the packaged adhesive formed as individual forms in an adhesive application process, and the use of the packaged adhesive in the production of laminated articles, including nonwoven hygiene articles, disposable medical drapes, and also laminate constructions such as tapes and labels.
