Title:
TUFTED CARPET PRIMARY BASE FABRIC
Document Type and Number:
WIPO Patent Application WO/2014/171042
Kind Code:
A1
Abstract:
The problem to be solved by the present invention is to provide a tufted carpet primary base fabric in which, even after the tufting process, the junctions between long fibers in the primary base fabric are maintained and form stability is kept. This tufted carpet primary base fabric is configured from a nonwoven fabric in which the long fibers having a fineness of 10 decitex or greater are the constituent fibers. The cross-sectional shape of the long fibers is characterized by linking substantially "Y"-shaped bottom ends up and down and to the left and right (below, this shape is referred to as a "substantially Y4 shape"). The long fibers are of a composite-type polyester, wherein the substantially "V"-shaped parts (6) of the substantially Y4 shape are formed from a low melting point polyester, and the remaining, substantially "+"-shaped part (5) is formed from a high melting point polyester. The long fibers are bonded together by fusion of the low melting point polyester.
