Abstract

The invention relates to a manufacturing method for two-layer two-color flannel imitation snowflake two-color split leather and belongs to the technical field of leather. The manufacturing method forthe two-layer two-color flannel imitation snowflake two-color split leather comprises the following steps that the processed and dyed split leather is taken, rewetting, retanning, leather basifying, neutralizing, fatliquoring, acid fixing, color fixing, dyeing, drying, drum milling and leather grinding are sequentially performed, and the two-layer two-color flannel imitation snowflake two-color split leather is obtained. The manufactured two-layer two-color flannel imitation snowflake two-color split leather not only has the excellent tensile property, the good abrasion and fading resistance and the good waterproofness, but also has the obvious two-color appearance, the soft hand feel, the smooth texture, good skin friendliness and good elasticity.

Description

technical field [0001] The invention belongs to the technical field of leather, in particular to a method for making two-layer double-color flannel imitation snowflake double-color double-layer leather. Background technique [0002] The color of flannel is pure and generous, which can be divided into light gray, medium gray and dark gray. The weight of flannel is high, the plush is relatively fine and dense, the fabric is thick, and it has good warmth retention. The surface of flannel has a plump and fine layer. It is covered with fluff, does not reveal texture, feels soft and flat, and has a slightly thinner body bone than Melton. After milling and fluffing, the hand feels full and the suede is fine. [0003] But flannel does not have two-color effect, and there is no example of flannel imitating snowflake two-color at present in China, therefore, the applicant provides a kind of manufacturing method of two-layer two-color flannel imitating snowflake two-color two-color le...
