METHOD FOR MANUFACTURING A CARPET OR A RUG AND A CARPET OR RUG OBTAINED THEREBY
Method for manufacturing a carpet or a rug, comprising the following steps: the step (S1-S2) of providing a primary backing (1), being a woven or non-woven layer comprising filaments (2) of polyethyleneterephthalate and copolymer of polyethyleneterephthalate, the coPET having a lower melting temperature than the PET and wherein said PET is available in said primary backing (1) in a higher amount than said coPET; the step of providing a glue layer (11) consisting for 50% or more out of coPET; the step of tufting yarn at least into said primary backing (1); the step of activating said glue layer (11) at least for partially fixing said yarn (12) on said primary backing (1).
The invention also concerns carpets (16) and rugs that are obtained or obtainable by means of such method.
Method for manufacturing multilayered coated fabric for personal protective equipment
A coating fabric and method of manufacturing the same are provided. A coated fabric includes a base coating layer. The base coating layer defines a smooth coating to resist liquid penetration to the fabric. The coated fabric also includes a middle foam coating layer that is deposited on at least a portion of the base coating layer. The middle foam layer defines a middle layer foam density and is configured to absorb at least a portion of liquid. The coated fabric further includes an outer foam coating layer that is deposited on at least a portion of the middle foam coating later. The outer foam layer defines an outer layer foam density and is configured with holes to allow liquid to penetrate to the middle foam layer. The middle layer foam density is less than the outer layer foam density. A corresponding method of manufacturing is also provided.
Recyclable single polymer floorcovering article
This invention relates to tufted floorcovering articles, including carpet tiles and broadloom carpet. In particular, this invention relates to tufted floorcovering articles made from the family of polymers known as polyester. Specifically, this invention relates to tufted carpet tile products made from polyester. The polyester carpet tiles meet commercial performance specifications and are fully end-of-life recyclable.
Binding strength improvement in laminated carpet tiles
Prior art teaches to apply strands of a hot melt adhesive on a primary backing of a textile product, such as a carpet or carpet tile, before adhering a secondary backing. In some cases, all portions of the strands may not contribute to the adhesion strength. Adjusting the viscosity of the hot melt adhesive may make the strands less flexible as they lay across the irregular features of the backstitching of a primary backing so they provide greater adhesion to the secondary backing. Alternatively, applying the hot melt adhesive to the secondary backing will also be used to create sufficient adhesion. Preferentially, using an air knife to prevent the strands from forming and/or to press the hot melt adhesive into the primary backing may also be used to create sufficient adhesion. These methods provide greater adhesion between the primary and secondary backings with less hot melt adhesive.
Method for producing an artificial turf
The invention relates to method for producing an artificial turf, comprising the following steps: providing a carrier material having a top and a bottom, providing a plurality of fibres, wherein each fibre comprises two ends extending from the top of the carrier material and comprising a connected region arranged in a loop-like manner at the bottom of the carrier material; feeding the carrier material with the fibres to a heated rotating calender roller; guiding the carrier material with the fibres over at least one sub-region of the surface of the heated rotating calender roller, wherein the connected regions of the fibres and the bottom of the carrier material face the calender roller; during the guiding of the carrier material with the fibres over the at least one sub-region of the surface of the heated rotating calender roller: transferring heat from the heated rotating calender roller to the carrier material with the fibres, and fusing the connected regions of the fibres with the bottom of the carrier material to the artificial turf, and removing and cooling the artificial turf. The invention further relates to an artificial turf comprising: a carrier material having a top and a bottom; a plurality of fibres, wherein each fibre comprises two ends extending from the top of the carrier material and comprising a connected region arranged in a loop-like manner at the bottom of the carrier material, wherein the carrier material is fused at the bottom to the connected regions of the fibres.
POLYOLEFIN RECYCLABLE ARTIFICIAL TURF AND ITS USE IN STATUES
Disclosed are a polyolefin recyclable artificial turf and its use in statues, wherein the recyclable artificial turf includes artificial grass filaments, a primary backing layer and a secondary backing layer sequentially from top to bottom; materials used for the artificial grass filaments, the primary backing layer and the secondary backing layer are all polyolefin; the primary backing layer is tufted with the artificial grass filaments, and root of the artificial grass filaments penetrates through the bottom of the primary backing layer and forms root grass filaments; the polyolefin used for the artificial grass filaments has a melting point of lower than 120 C.; the artificial turf designed by the present application can be recyclable and reduce the cost of processing and manufacturing, and the artificial turf can be reused as a filling material for statues, improving the utilization rate of the product.
