Disclosed are a medical fiberous structure and a method for preparing the same, wherein the medical fiberous structure comprises calcium carboxymethyl cellulose and a chitosan compound, at least one of the calcium carboxymethyl cellulose and the chitosan compound having a fibrous shape.

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.

Disclosed is an artificial leather base material including: a non-woven fabric that is an entangle body of fibers (A) and fibers (B); and an elastic polymer applied inside the non-woven fabric, wherein the fibers (A) are crimped fibers that are formed from two types of resins with intrinsic viscosities different from each other, and that are filaments of 0.6 dtex or more, and the fibers (B) are ultrafine fibers of less than 0.6 dtex.

A method for preparing carpet by using polyurethane to anneal secondary backing to a greige, comprising fibers attached to a primary backing using a roller application system. The greige is conditioned prior to coating and the polyurethane coated greige is contacted with the secondary backing and the laminate is tensioned and supported to maintain the laminate structure substantially through the polyurethane curing process.
