性、耐菌性などにおいて天然皮革よりも優れた特性を備
えさせることができる、有用な素材である。The above synthetic leather has a good feel, suppleness, natural texture,
It is possible to provide properties equivalent to natural leather in terms of moisture absorption and desorption properties, non-static properties, etc., and properties superior to natural leather in terms of water resistance, durability, workability, antibacterial properties, etc. It is a useful material.
従来、天然皮革の微粉とポリウレタンの混合物から成っ
ていた。Traditionally, it consists of a mixture of natural leather fines and polyurethane.
しかし、ポリウレタンの比重が1.2で割合に大きいた
め、天然皮革の微粉とポリウレタンの混合物の嵩比重が
0.38〜0.50g/cc程度となり、衣類などの用
途には、−層軽量化することが要望されていた。However, since the specific gravity of polyurethane is relatively large at 1.2, the bulk specific gravity of the mixture of fine natural leather powder and polyurethane is about 0.38 to 0.50 g/cc, which is not suitable for applications such as clothing. It was requested to do so.
本発明の目的は、天然皮革の微粉と樹脂を含む合成皮革
を、衣類などの用途に好適な十分に軽いものに改良し、
しかも、保温性の向上を併せ図れるようにする点にある
。The purpose of the present invention is to improve synthetic leather containing fine powder of natural leather and resin into a sufficiently light material suitable for use in clothing, etc.
Moreover, it is possible to improve heat retention at the same time.
本発明の特徴構成は、天然皮革の微粉と樹脂の混合物に
微小中空粒子を含有させたことにあり、その作用効果は
次の通りである。The characteristic structure of the present invention is that a mixture of natural leather fine powder and resin contains microscopic hollow particles, and the effects thereof are as follows.
つまり、微小中空粒子の嵩比重は、例えば粒径10〜2
50μmのホウケイ酸ガラス製の場合に0.15〜0.
19g/CC程度というように、天然皮革の微粉とポリ
ウレタンの混合物の嵩比重(0,38〜0、50g/c
c程度) よりも十分に小さくできるのであり、したが
って、適量の微小中空粒子を含有させることによって、
天然皮革の微粉と樹脂の混合物の特性を損うこと無く、
合成皮革の軽量化を十分に図れる。In other words, the bulk specific gravity of the micro hollow particles is, for example, a particle size of 10 to 2.
0.15 to 0.0 in the case of 50 μm borosilicate glass.
The bulk specific gravity of the mixture of natural leather fine powder and polyurethane is about 19g/CC (0.38~0.50g/c).
Therefore, by containing an appropriate amount of micro hollow particles,
without impairing the properties of the mixture of natural leather fine powder and resin.
The weight of synthetic leather can be sufficiently reduced.
その上、微小中空粒子に封入されている気体の断熱作用
によって、合成皮革の保温性を十分に向上できる。Furthermore, the heat retention properties of the synthetic leather can be sufficiently improved due to the heat insulating effect of the gas enclosed in the micro hollow particles.
その結果、天然皮革の微粉と樹脂を含む合成皮革の特性
を十分に活かしながら、合成皮革の軽量化と保温性向上
を十分に図れ、衣類などの用途に一段と優れた合成皮革
を提供できるようになった。As a result, we have been able to make full use of the characteristics of synthetic leather, which contains fine powder from natural leather and resin, while sufficiently reducing the weight and improving heat retention of synthetic leather, making it possible to provide synthetic leather that is even better for uses such as clothing. became.
