Abstract
The present invention provides pile compositions comprising 2% by weight or more of porous expanded fibers with expansion ratio 3% or higher as fibers composing the pile part. This invention enables providing pile compositions which give excellent animal hair like feeling and external appearance; that is, pile part's lightness, bulkiness, soft touch, elasticity, coloring and loosenability.
Claims4
Animal hair-like pile compositions comprising 2% by weight or more of porous expanded fibers formed of acrylonitrile-based polymers with expansion ratios greater than or equal to 3% through gas contained in the fibers during their manufacturing process and less than or equal to 98% weight of non-porous expanded fibers as the fibers comprising the pile part.
