Abstract

The invention discloses skin-imitated synthetic leather, and a manufacturing method and apparatus for the same. The skin-imitated synthetic leather is prepared through the following steps: applying an impregnating material on a base cloth to form a bottom green body by using a wet method, preparing a base from a coating, and carrying out solidification, rinsing and drying to obtain the skin-imitated synthetic leather, wherein, the impregnating material comprises, by weight, 100 parts of a speciality resin, 180 to 250 parts of DMF (dimethyl formamide), 0.05 to 0.5 part of an anti-foaming agent, 0.5 part to 2 parts of a wetting agent and 2 to 5 parts of color paste. The skin-imitated synthetic leather provided in the invention has the advantages of good water resistance and air permeability, soft handle, authentic skin feel, low production cost compared to superfine fibrous leather and capacity of compensating for restriction on related manufacturing industries caused by scarcity of animal skin.

Description

technical field [0001] The invention relates to the field of synthetic leather manufacturing, in particular to a simulated leather synthetic leather, a manufacturing method and a device thereof. Background technique [0002] Synthetic leather is a kind of base material with various cloth bases, and resin is coated on the base material to make it have various patterns, patterns, functions and feel. [0003] At present, the application of synthetic leather in the fields of clothing, sports shoes, sofas and bags is more and more extensive, which to a large extent makes up for the limitation caused by the scarcity of animal skins to related manufacturing industries. In an industrial sense, it is not only suitable for modern scale production, but also protects ecology, reduces environmental pollution, and makes full use of non-natural resources. However, the traditional synthetic leather has the disadvantages of hard hand feeling, strong plastic feeling, airtight surface and eas...
