preparation example Construction

[0144] The invention provides a kind of preparation method of wool leather integrated composite material, comprises the following steps:

[0145] 1) After bonding the braided fabric with wool layer or the integrated material of real fur with the base material through adhesive glue, a composite material with a base material backing is obtained;

[0146] 2) After compounding the primer layer on the base material surface of the composite material with the base material backing obtained in the above steps, after drying, a semi-finished product is obtained;

[0147] 3) Ironing and laminating the coating film surface of the release paper coated with the coating film and the base coat of the semi-finished product obtained in the above steps, and then drying again to obtain a wool-leather integrated composite material.

[0148] Concrete can be the following steps:

[0149] 1`) After bonding the braided fabric with wool layer or the integrated material of real fur and the base materia...

[0219] Fur-leather integrated composite material with braided wool

[0220] The first step: use PUR hot melt adhesive to apply the hot melt adhesive on the suede through the composite laminating equipment and laminate it with the knitted fabric surface to form a composite knitted wool material with a base fabric backing.

[0221] Among them, suede thickness: 0.4mm, suede weight: 210g / m 2 ;

[0222] Hot melt adhesive bonding pressure: 60kg / cm 2 , Hot melt adhesive bonding speed: 4m / min, bonding temperature 140°C.

[0223] The second step: release paper coating: the coating film material with the following formula is used for coating with a roller coating machine, and then dried in an oven.

[0224] Among them, the coating film layer process formula:

[0225] Waterborne polyurethane resin 1225: 27%

[0226] Polyurethane Dispersion 127: 23%

[0227] Water-soluble synthetic resin RC-2349: 16%

Abstract

The invention provides a fur and leather integrated composite material which comprises a coating film, a primer layer compounded on the coating film, a base material compounded on the primer layer, anadhesive layer compounded on the base material and a braided fabric layer with a fur layer compounded on the adhesive layer or a real fur integral layer compounded on the adhesive layer, wherein theadhesive layer is compounded on the braided fabric face of the braided fabric layer with the fur layer, and the adhesive layer is compounded on the skin layer of the real fur integral layer. Accordingto the fur and leather integrated composite material, the thickness of the coating can be controlled at the micron level, any grain or visual effect can be realized by the style of the board surface,meanwhile, the physical property index of the product is good, the quality stability and consistency are good, the production process is simple, the environmental protection efficiency is high, and the fur and leather integrated composite material is environmentally friendly and sustainable, and is suitable for large-scale production popularization and application.

Description

technical field [0001] The invention belongs to the technical field of fur leather treatment and processing, and relates to a fur-leather integrated composite material and a preparation method thereof, and a real fur-leather integrated composite material and a preparation method thereof. Background technique [0002] The processing of fur leather has a history of thousands of years. After a long period of development, the processing of fur leather has developed into an important industrial technology field from the original simple manual operation. Fur and leather integration refers to the leather (fur leather) with hair on one side obtained by tanning, dyeing and finishing the animal skin with hair. The whole fur leather is composed of two parts: the wool quilt and the leather plate, wherein the wool quilt refers to the side with animal hair, and the leather plate is the leather surface with natural grain and luster. [0003] Due to the scarcity and price factors of wool a...
