Abstract

The invention discloses figured sea-island superfine fiber suede leather with a writing effect and a preparation method thereof. The preparation method comprises the following steps: (1) impregnating a superfine fiber polyurethane synthetic leather base cloth into a raising finishing agent to be padded, and then drying and setting the product to prepare superfine fiber suede leather with an oriented nap effect, wherein the raising finishing agent comprises the following components in parts by weight: 1-8 parts of pilling agent and 100 parts of deionized water; the pilling agent is a polyvalent alcohol interfacial agent compound; (2) unidirectionally polishing the two sides of the product obtained in the step (1) with raw emery paper, and then unidirectionally polishing the two sides with fine emery paper, wherein the polishing directions of the raw emery paper and the fine emery paper are consistent; (3) rubbing the product in the step (2) to generate grains, thus obtaining the figured sea-island superfine fiber suede leather with the writing effect. The suede leather has full hand feeling, writing effect, beautiful appearance, good genuine leather imitating effect and high added value.

Description

technical field [0001] The invention relates to a preparation method of Dingdao superfine fiber synthetic leather. Background technique [0002] At present, the sea-island microfibers used in domestic production are divided into indeterminate island-type sea-island microfibers and fixed-island-type sea-island microfibers according to the production technology adopted. The islands in the indeterminate island-type sea-island microfibers are uncontrollable and discontinuous on the longitudinal axis. After solvent treatment, ultrafine fibers with thick and thin, irregular lengths and short lengths are formed; while the fixed-island-type sea-island ultrafine fibers The fiber is continuous on the longitudinal axis, and it is a uniform ultrafine fiber with a fixed number of islands, a uniform fineness, and a consistent length. The number of islands in the fixed island type sea island microfiber generally has several specifications such as 16 islands, 24 islands, 37 islands, and 64...
