Example Embodiment

[0024] Example 1:

[0025] 1) In parts by weight, dissolve 3 parts of neutral dye with 65 parts of water, prepare a neutral dye solution and put it into the dipping tank, and then pass the non-fixed island type microfiber synthetic leather base cloth through the dipping tank Dip the neutral dye solution, and then control the dipping amount of the neutral dye solution to be 80% of the weight of the non-fixed island-type ultrafine fiber synthetic leather base fabric through a roller, and then dry it in an oven at 120°C to obtain the dyed base fabric ;

[0026] 2) In parts by weight, 2 parts of the block hydrophilic silicone oil N-3401 is diluted with 80 parts of water and then put into the dipping tank, and then the dyed base cloth is passed through the dipping tank to make the dyed base cloth impregnated with the silicone emulsion. Then control the immersion amount of the neutral dye solution to 100% of the weight of the non-fixed island-type superfine fiber synthetic leather base ...

Example Embodiment

[0028] Example 2:

[0029] 1) In parts by weight, dissolve 5 parts of neutral dye with 70 parts of water, prepare a neutral dye solution and put it into the dipping tank, and then pass the non-fixed island-type microfiber synthetic leather base cloth through the dipping tank Dip the neutral dye solution, and then control the dipping amount of the neutral dye solution by a roller to 60% of the weight of the non-fixed island type superfine fiber synthetic leather base fabric, and then dry it in an oven at 130°C to obtain the dye base fabric ;

[0030] 2) In parts by weight, 4 parts of high-concentration silicone resin emulsion smoothing agent N-3508 is diluted with 90 parts of water and then put into the dipping tank, and then the dyed base cloth is passed through the dipping tank to make the dyed base cloth impregnated with organic Silicone emulsion, and then control the amount of immersion of the neutral dye solution to 80% of the weight of the non-fixed island-type superfine fibe...

Abstract

The invention relates to a successively-impregnating after-finishing method of suede-like superfine fiber synthetic leather. The method comprises the steps of impregnating unfigured islands-in-sea superfine fiber synthetic leather base cloth with neutral dye liquid, drying for dyeing the unfigured islands-in-sea superfine fiber synthetic leather base cloth to obtain the dyed base cloth; impregnating the dyed base cloth with organic silicone emulsion, and drying the dyed base cloth for softening treatment to obtain softened base cloth; impregnating the softened base cloth with fluororesin emulsion, and drying for three-proofing treatment to the softened base cloth, thereby achieving successively-impregnating after-finishing to the suede-like superfine fiber synthetic leather. The method totally adopts the environment-friendly materials and the clean production process to obtain the water-proofing suede-like superfine fiber synthetic leather, therefore, the level of the suede-like superfine fiber synthetic leather is greatly improved and good application prospect is achieved.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to a continuous dipping finishing method for suede superfine fiber synthetic leather. Background technique [0002] Natural leather resources are limited, and the production process will produce relatively large pollution. The development of artificial synthetic leather with excellent performance has become the pursuit of human beings. Among them, the superfine fiber non-woven fabric with three-dimensional network structure is used as the reinforcing material, and the superfine fiber synthetic leather obtained by impregnating polyurethane is close to the microfiber in terms of internal microstructure, appearance texture, physical properties and people's wearing comfort. Made of natural leather. At present, more than 90% of the world's high-end sports shoes are made of microfiber synthetic leather, most of the three major ball leathers are made of microfiber synthetic leat...
