Abstract:
(EN) Grained artificial leather includes an artificial leather substrate and a grained surface layer laminated onto the artificial leather substrate. The grained artificial leather substrate includes fiber entangled bodies that include ultrafine fibers with an average fiber density of 0.4 dtex or less, a macromolecular elastic bodies, and microparticles having an average particle size of 10 µm or less. The content for the microparticles is 10 – 40% by mass, and the proportion of macromolecular elastic bodies in the total amount of the macromolecular elastic bodies and microparticles is 20 – 80% by mass. Furthermore, the total of the apparent density of the macromolecular elastic bodies and the apparent density of the microparticles is 0.23 – 0.55 g/cm3.
(FR) L'invention concerne un cuir artificiel grainé comprenant un substrat en cuir artificiel et une couche de surface grainée stratifiée sur le substrat en cuir artificiel. Le substrat en cuir artificiel grainé comprend des corps entremêlés de fibres qui comprennent des fibres ultrafines présentant une densité de fibre moyenne de 0,4 dtex ou moins, des corps élastiques macromoléculaires et des microparticules présentant une taille moyenne de particule de 10 µm ou moins. La teneur des microparticules est de 10 à 40 % en masse et la proportion de corps élastiques macromoléculaires dans la quantité totale des corps élastiques macromoléculaires et des microparticules est de 20 à 80 % en masse. En outre, le total de la densité apparente des corps élastiques macromoléculaires et de la densité apparente des microparticules est de 0,23 à 0,55 g/cm3.
(JA) 人工皮革基材と人工皮革基材に積層された銀面層とを含む銀付調人工皮革である。人工皮革基材は、平均繊度0.4dtex以下の極細繊維を含む繊維絡合体と高分子弾性体と10μm以下の平均粒子径を有する微粒子とを含む。微粒子の含有割合は10~40質量%であり、高分子弾性体と微粒子との総量中の高分子弾性体の割合が20~80質量%である。そして、高分子弾性体の見掛け密度と微粒子の見掛け密度との合計が0.23~0.55g/cmである。
