A method of manufacturing a plurality of secondary containment panels and assembling and installing the panels in a secondary containment system of an above-ground liquid storage tank or other retention facility includes forming a plurality of flexible substrate pieces. A liquid impermeable coating is applied to the upper surface of each piece such that an edge segment of the piece remains uncoated. The coating is applied to the substrate piece in an indoor enclosure using a computer controlled robotic sprayer that applies a uniform coating. A system for coating secondary containment panels. An apparatus for spraying a coating on secondary containment panels. The apparatus may be computer controlled and operate automatically to coat the surface of the panel.

A healthier carpet employing UV light-transmitting threads, which facilitate UV light transmittance down from the surface of the carpet, through the interior of the carpet, and into the primary backing of the carpet. The UV light can destroy bacteria, molds, viruses, yeast, and other microorganisms, which are present in the carpet. An external UV light source, with UV wavelengths from 100-400 nm, can be passed over the carpet for effective sanitization.

This invention relates to installation methods for a multi-component floor mat. The floor mat typically contains a textile component and a base component. Alignment and deployment of the textile component with the base component in an efficient manner is described herein.

A carrier material includes at least a first thermoplastic fiber layer and a second thermoplastic fiber layer. At least a part of the first thermoplastic fiber layer and/or the second thermoplastic fiber layer at at least one boundary of the carrier material is removed, to provide a first part of a form-fit connection. The carrier material can be used in bituminous roofing membranes, roofing underlayment sheets, carriers for filter media, primary backings for tufted carpets and (cushion) vinyl floor coverings.

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.

The present disclosure relates to a nonwoven fabric for primary carpet backing and a method for manufacturing same, the non-woven fabric having different colors on the two sides thereof and improved mechanical property. More specifically, the present disclosure relates to a non-woven fabric for primary carpet backing and a method for manufacturing same, wherein any one surface of the two surfaces of appears in a range of white to grey and the opposite surface thereof appears in a range of dark grey to black, so that the separate manufacture of non-woven fabrics having various colors according to carpet colors is not required, which facilitates the inventory management of the non-woven fabric, achieves color matching between a carpet pile yarn and a nonwoven fabric for primary carpet backing, and improve the efficiency of the carpet manufacturing process.

A novel carpet tile is provided with a roller applied polyurethane adhesive layer at a rate of less than 45 ounces per square yard, resulting in a lightweight backing with exceptional dimensional stability.

This invention relates to a washable multi-component floor mat. The floor mat contains a textile component and a base component. The textile component and the base component are attached to one another by at least one surface attraction means and at least one edge attachment means. The textile component is designed to be soiled, washed, and re-used, thereby providing ideal end-use applications in areas such as building entryways. The present invention eliminates the need to wash the base component of the floor mat which results in environmental, cost and labor conservation.

A carpet tile comprises a primary backing layer comprising a flexible substrate with fiber tufts extending through and from one surface of the substrate to define, in use, the upper wear surface of the tile. A pre-coat adhesive layer formed from an aqueous copolymer dispersion is provided on the opposite surface of the primary backing substrate to secure the fiber tufts to the substrate and a secondary adhesive layer formed from an aqueous copolymer dispersion is provided on the pre-coat adhesive layer. A fiberglass scrim is secured to the secondary adhesive layer and an outer backing or cap layer covers the fiberglass scrim.

Textile fabrics consolidated with a binder that is made from a binder system are described. The binder system may include: a) 30% or less by dry weight of at least one polymer based on polyvinyl alcohol; b) 70% or more by dry weight of at least one starch, wherein the at least one starch comprises 50% by weight or more of one or more natural starches based on the total weight of the at least one starch; c) 0 to 10% by dry weight of at least one crosslinker; d) 0 to 10% by dry weight of at least one filler; and e) 0 to 10% by dry weight of at least one additive, wherein a sum of components a) through e) is 100% by dry weight of the binder system. Method of making the textile fabrics consolidated with binders made from the binder systems are also described.
