Problems solved by technology

[0023] Another object of the present invention is to provide a double-sided waterproof suede dual-purpose leather production method for wool quilts and leather boards. Fiber waterproofing agent, using microwave heating technology to fix the waterproofing agent on the wool fiber to realize the waterproofing of the wool fiber, the scales of the wool fiber will not be damaged by heating, which solves the problem that the waterproofing agent is difficult to be fixed on the wool fiber and the deep layer of the wool quilt Still can't fix the problem

Embodiment 1

[0178] Example 1 Leather board waterproof treatment and dyeing, retanning, fatliquoring process treatment

[0179] The dual-purpose suede leather base is first processed as follows:

[0180] 1. Dyeing quilt

[0181] Water temperature: 60~65℃

[0182] Leveling agent DP (Fanbo Company): 0.5g / L

[0183] Salt: 10g / L

[0184] Dye (dyed reddish brown): Xili fur red brown R-OD 0.3g / L Xili fur golden GMK0.1g / L (Beijing Fanbo Technology Co., Ltd.))

[0185] Formic acid: 1g / L

[0186] Operation: Adjust the water temperature and water volume, add leveling agent and salt, and then cast the skin. After 15 minutes, add the dye. After the dye is melted with hot water, add it. After 1 hour, add 0.5g / L formic acid to fix the color, and then swipe. Add 0.5g / L formic acid for 30 minutes, and then paddle for 30 minutes to wash with water. The amount of salt or formic acid used does not limit the present invention.

[0187] 2. Retanning

[0188] Water temperature: 35°C

[0189] Penetrant ...

Embodiment 2

[0224] Embodiment 2 hair is waterproofed

[0225] The fur obtained among the middle of embodiment 1 is carried out following process processing:

[0226] 1. Apply wool repellent

[0227] Equipment: grooving

[0228] Temperature: room temperature

[0229] Liquid ratio: 10

[0230] Water repellent: fluorine-based polyacrylic acid water and oil repellent finishing agent Advanproof WRC-LT (Hong Kong Pioneer Co., Ltd.) 5~10g / L

[0231] Operation: Add water to the scratching groove, add waterproofing agent, scratch evenly, soak the fur in the waterproofing agent solution, row for two hours, and the skin will come out.

[0232] 2. Squeeze

[0233] Operation: Use a vertical rolling mill to squeeze the liquid, and the residual rate of the liquid rolling is about 70% (v / v). The excess liquid squeeze rate is the liquid in the fur.

[0234] 3. Dry the skin board

[0235] Operation: Hang the leather board facing out to dry naturally.

[0236] 4. Fixed wool waterproofing agent

[...

Embodiment 3

[0239] Example 3 Detection of double-sided waterproof suede dual-purpose leather of wool quilt and leather board

[0240] After the dual-purpose suede leather base is processed by the process of embodiment 1 and embodiment 2, the micrograph of the appearance change of wool fiber before and after waterproof treatment is as follows figure 1 , figure 2 shown.

[0241] Depend on figure 1 and figure 2 It can be seen that after the suede dual-purpose leather has been processed by the three major processes of suede dual-purpose leather blank production, leather panel waterproofing and dyeing, retanning, fatliquoring and wool quilt waterproofing, the surface scales of the wool fiber Many gully-shaped fine lines have been significantly improved, and the surface of the wool fiber is covered with a layer of water-repellent film, which enhances the water-repellent effect of the wool fiber and increases the flow speed of water droplets on its surface.

[0242] The wool quilt and doub...

Abstract

The invention discloses a manufacturing method of double-faced waterproofing pile-face dual-purpose leather of indumentum and leather boards; the method comprises three parts that: manufacturing process of the pile-face dual-purpose crust leather and waterproofing treatment of the leather boards, the process of dyeing, retanning and stuffing, and indumentum waterproofing process. The physical and chemical indexes, specialty chemical index, waterproofing index, anti-washing index and dry cleaning resistant index of the manufactured double-faced waterproofing pile-face dual-purpose leather of indumentum and leather boards are all in accordance with international or industrial standards.

Description

technical field [0001] The invention relates to a production method of two kinds of wool leather, in particular to a production method of a double-sided waterproof suede wool dual-purpose leather. Background technique [0002] In the modern leather industry, the mutual penetration of fur-making and tanning technology is increasing, and many products have reached the point where it is difficult to distinguish between fur and leather, and non-fur and non-leather. Fur dual-purpose leather is a combination of leather and fur styles. Its craftsmanship integrates tanning and fur processing. It is an updated product and a high value-added product for fur. It has a broad potential market. An upward trend is the main direction for the development of fur products for a period of time in the future. [0003] In the past, fur leather products generally refer to smooth or suede leather of various colors made from sheep skin and flesh, and fur quilts can be made into various colors and t...
