Abstract

The invention discloses soft and scratch-resistant fixed island ultrafine fiber suede leather and a preparation method thereof. The preparation method includes the following steps that 1, fixed island ultrafine fiber suede leather is soaked in a finishing agent, padding is carried out, and then dry-shaping is carried out, wherein the finishing agent is prepared from, by weight, 0.5-10 parts of softener, 0.1-8 parts of assistant A, 1-10 parts of assistant B and 100 parts of water, the softener is one or more of organosilicone softeners and films, the assistant A is one or more of ethylene-vinyl acetate copolymer emulsion, hydroxyethyl cellulose, polyvinyl alcohol and carboxymethylcellulose, and the assistant B is waterborne polyurethane emulsion; 2, the product obtained in the step 1 is subjected to grain kneading in a grain kneading machine or an air kneading machine, and the product can be obtained. Fine hair of the suede leather is denser and full in hand feeling, and the prepared ultrafine fiber suede leather has the advantages of being soft, resistant to scratches, attractive in appearance, good in leather imitation effect and high in added value.

Description

technical field [0001] The invention relates to a superfine fiber suede, in particular to a preparation method of Dingshima superfine fiber suede. 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...
