<p>#CMT# #/CMT# The non-woven fabric used, is a spun-bonded fleece. This is optionally pre-bonded. It contains multi-component filaments, including at least one high-melting component and at least one low-melting component. The latter can be thermally-activated. Bi-component filaments are used, in a proportion preferably exceeding 15%, based on the total fabric weight. The filament structure is core/casing, side-by-side, island-in-the-sea and/or pie (or hollow pie). The low melting component is CoPET, CoPA, PA, PP, CoPP, atactic PP and/or PE. The high-melting component is PET, PLA, PBT, PA and/or PP. #CMT# : #/CMT# The spun fleece contains up to 75 wt% of staple fibers. The fibers and/or filaments are crimped. At least one layer forming a velour surface is included; this is made from needled fleece as described. A heavy backing layer is included on the rear of the velour surface, optionally with a sound-damping layer. One or more bonding layers are included between the other layers. These include fibers or filaments of low- and high-melting polymer as described. The filaments and/or fibers of all layers are made from the same polymer and/or its derivatives. #CMT#USE : #/CMT# A non-woven velour produced by needling through fleece laid on brush-type stitching underlay. The velour is used as an indoor textile covering for objects and in living areas. It is used for cladding vehicle interiors, i.e. the passenger compartment or trunk. It is used as a floor covering. (All claimed) #CMT#ADVANTAGE : #/CMT# The new fabric, especially useful for interior coverings, is environmentally compatible, hazard-free and of high quality. It has very good mechanical properties and is especially wear-resistant, despite using no additional chemical binders. A costly latex coating normally used to make vehicle linings, is obviated. Volatile hydrocarbons are absent. The product is based on economically-manufactured, very lightweight, spun fleece.</p> |
