Abstract:
(EN) The present invention relates to the technical field of superfine fiber synthetic leather, and particularly relates to a production method of superfine fiber synthetic leather with a density gradient structure. In the production method, solvent-free polyurethane is introduced for application, so that the solvent-free polyurethane permeates into the surface layer of a superfine fiber non-woven fabric to form a compact layer, and then impregnation, decrement and post-finishing process are carried out, and finally a structure which is similar to dermis and has a compact surface layer and density gradient, is formed.
(FR) La présente invention concerne le domaine technique du cuir synthétique à fibres superfines, et concerne en particulier un procédé de production de cuir synthétique à fibres superfines présentant une structure à gradient de densité. Dans le procédé de production, du polyuréthane exempt de solvant est introduit pour application, de sorte que le polyuréthane exempt de solvant pénètre dans la couche de surface d'un tissu non-tissé à fibres superfines pour former une couche compacte, puis des processus d'imprégnation, de décrémentation et de post-traitement de finition sont effectués, et enfin une structure qui est similaire au derme et qui présente une couche de surface compacte et un gradient de densité est formée.
(ZH) 本发明涉及超细纤维合成革技术领域,尤其是一种具有密度梯度结构的超细纤维合成革的生产方法。本生产方法引入无溶剂聚氨酯应用,使无溶剂聚氨酯渗透在超纤无纺布表层形成致密层,再实施含浸、减量、后整理工艺,最终形成类似于真皮的表层致密的具有密度梯度的结构。
