Abstract
The invention discloses a wet waterproof moisture-permeable leather production method. The method comprises the following steps: uniformly mixing 5-10 parts of dimethyl formamide with 0.5-2 parts of a color paste, and filtering; adding 80-100 parts of dimethyl formamide, 1-3 parts of a cell modifier and 1-2 parts of a bridging agent, and uniformly mixing; adding 100kg of a polyurethane wet waterproof moisture-permeable resin, uniformly stirring, and deaerating to obtain a coating; knife-coating the coating on a base cloth, solidifying, squeezing, washing with water, and drying to obtain a finished product. A wet waterproof moisture-permeable layer is formed after the wet slurry is knife-coated on the base cloth, and has good water permeability and high water pressure resistance. A result of detection shows that the water pressure resistance of the wet waterproof moisture-permeable layer is greater than 5000mm.H2O (JISL1092B standard), and the moisture permeability of the wet waterproof moisture-permeable layer is greater than 5000g/m<2>.d (JISL 1099B standard). Clothes made by using the obtained wet waterproof moisture-permeable leather have the advantages of comfortable wearing, difficult moldy damage and durability.
Description
Technical field
The present invention relates to a kind of artificial leather preparation method, particularly a kind of wet method Water-proof artificial leather production method.
Background technology
In haberdashery, usually use artificial leather material, conventional artificial leather is all on base cloth, to be coated with to scrape wet-mixing thing formation wet method bass, then on wet method bass, pasting dry method veneer forms, its poisture-penetrability is poor, in dress, because movement human is usually perspired, give people a kind of vexed wet air-locked sensation, affect snugness of fit, wear for a long time moist dress ornament and also easily cause human body skin bacterial infection, also easily cause the dress ornament damage of going mouldy.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of wet method Water-proof artificial leather production method, this wet method Water-proof artificial leather production method technique is simple, and the water pressure resistance of product performance of producing is high, and poisture-penetrability is good.
The present invention for the technical scheme that solves its technical problem and adopt is: a kind of wet method Water-proof artificial leather production method, and concrete steps are as follows:
Step 1: wet-mixing batching:
A. by 5～10kg dimethyl formamide and 0.5～2kg mill base high-speed stirred 80～100 minutes, then filter stand-by;
B. by the bridging agent mix and blend of 80～100kg dimethyl formamide, 1～3kg abscess conditioning agent and 1～2kg 20～30 minutes, then add the mixture having filtered in step a to stir stand-by;
C. 100kg polyurethane wet method Waterproof Breathable resin is joined in the mixture that step b forms, stir 30～40 minutes, deaeration 40～50 minutes;
Step 2: coating is produced:
By in step 1 the slurry of deaeration be coated with scrape on base cloth, in the dimethyl formamide aqueous solution that to immerse mass percentage concentration be 15-20%, solidify, then through at least one squezzing operation, obtain a kind of wet method Water-proof artificial leather finished product after washing and being dried again.
As a further improvement on the present invention, dimethyl formamide and stock white high-speed stirred 90 minutes in described step a.
As a further improvement on the present invention, in described step a, use 240 order nylon wires to filter the mixed liquor of dimethyl formamide and mill base.
As a further improvement on the present invention, in described step a, mill base used is stock white.
As a further improvement on the present invention, in described step b, mixture stirs 30 minutes.
As a further improvement on the present invention, in described step c, polyurethane wet method Waterproof Breathable resin is joined in the mixture that step b forms, stir 40 minutes, deaeration 45 minutes.
As a further improvement on the present invention, in step 2, base cloth is woven nylon measuring fiber.
As a further improvement on the present invention, not 20-25 rice/min of the speed of a motor vehicle in step 2.
The invention has the beneficial effects as follows: after wet method slurry of the present invention is coated with and scrapes on base cloth, form the wet method Waterproof Breathable layer of one deck with moisture-inhibiting aperture, it has good poisture-penetrability, and its water pressure resistance is high, through detecting, its water pressure resistance >5000mm.H2O (JISL 1092B standard), moisture-inhibiting >5000g/m2.d (JISL 1099B standard), it is processed into after dress ornament, comfortable and easy to wear, the damage that is difficult for going mouldy, durable in use.
