绒毛状人工皮革及其制造方法;ARTIFICIAL NAPPED LEATHER AND PRODUCTION METHOD THEREOF

摘要

本发明系关于一种绒毛状人工皮革之制造方法，其具备：准备纤维片的步骤，其中该纤维片包含纤度1dtex以下之极细纤维的不织布，该不织布含浸赋予有第一高分子弹性体；藉由对该纤维片之单面或双面施行起毛处理，而形成绒毛面的步骤；将含有对于指定溶剂具有可溶性之第二高分子弹性体的树脂液涂布于该绒毛面的步骤；以及在涂布有该树脂液之面，涂布该指定溶剂的步骤。本发明亦关于一种绒毛状人工皮革，其包含使不织布含浸赋予有第一高分子弹性体而成之纤维片，其中该不织布为纤度1dtex以下之极细纤维之缠结体；该纤维片在其单面或双面具有使极细纤维起毛而成之绒毛面，且于起毛之极细纤维的根部有第二高分子弹性体固着。; imparting a napped finish to one or both surfaces of the sheet by a treatment of raising the ultrafine fibers from the surface(s); applying to the napped surface(s), a liquid resin containing a second elastic polymeric body with solubility in a predetermined solvent; and applying the predetermined solvent to the liquid resin-applied surface(s). Also disclosed is an artificial napped leather including a fiber sheet including a non-woven fabric as the one given above, in which: one or both surfaces of the sheet has a napped finish with ultrafine fibers raised from the surface(s); and a second polymeric elastic body is firmly fixed to roots of the raised ultrafine fibers.
