摘要:
An artificial leather having a suede appearance and colours within the grey-black range and high colour fastness comprising a microfibrous component and an elastomeric matrix; the microfibrous component consisting of polyester microfibres having a count of 0.01 to 0.50 dtex; the elastomeric matrix consisting of polyurethane consisting of soft and hard segments; the ratio between the elastomeric matrix and the microfibrous component ranging from 20/80 and 50/50 by mass; the microfibrous component containing carbon black pigment in a percentage of 0.05 to 2.00% by mass; the elastomeric matrix containing carbon black pigment in a percentage of 0 to 10% by weight; the carbon black always having an average dimension smaller than 0.4 microns. The average length of the tassel is between 200 and 500 microns. The soft segments consist of at least one polycarbonate diol selected from polyalkylene carbonate diols and at least one polyester diol. The hard segments consist of urethane groups deriving from the reaction between free isocyanate groups and water. The total content of carbon black is between 0.025 and 6% by weight.
摘要:
A process for modifying a silicone elastomeric-based surface of an article where the coefficient of friction (COF) of the silicone elastomeric-based surface is generally reduced by at least 5% is disclosed. The process comprises subjecting the silicone elastomeric-based surface of the article to vacuum ultraviolet (UV) radiation.

Proposed are an eco-friendly high pressure hose fabric and an eco-friendly high pressure hose using the same. The eco-friendly high pressure hose fabric includes a textile woven from a polypropylene-based fiber, a first coating layer formed on one surface of the textile, a second coating layer formed on the other surface of the textile to extend longer than the length of the textile, a resin adhesive layer formed over the entirety of the top surface of the first coating layer and the top surface of the second coating layer extending longer than the length of the textile, and a film layer formed on the top surface of the resin adhesive layer to correspond to the length of the second coating layer. Ends of the second coating layer, the resin adhesive layer and the film layer, which extend longer than the length of the textile and are stacked on one another, form an extended portion of the fabric.
