Abstract
An artificial leather having chinchilla-like appearance and a natural suede-like feeling which comprising flocking piles of separable composite fibers which in transverse cross-section consist of at least three integral segments (A) of one polymer of polyamide and polyester wherein said segments diverge from each other substantially radially in the outward direction and extend to the perimeter of the fiber and wedge-shaped segments (B) of another polymer which fill the spaces between the segments (A) or consist of the above described segments (A), V-shaped segments (B') of the latter polymer and wedge-shaped segments (C) of the former polymer which fill the concavities of the V-shaped segments (B'), said V-shaped segments (B') and said wedge-shaped segments (C) filling the spaces between the segments (A), wherein all of the polymers extend to the perimeter of the fiber, on a substrate fabric applied with an adhesive, applying a swelling agent on the piles, brushing the thus treated piles to substantially separate each segment in the above described cross-section and then subjecting the brushed piles to a wet heat treatment.
