B, using roll by base fabric immerse polyurethane material in, and polyurethane material liquid level be located at the roll side center of circle below；
C, circulation step b, carry out 5 leaching material using 5 groups of rolls altogether, obtain C product；
D, to C product front carry out coating, apply one layer of polyurethane material；
E, solidification；
F, washing；
G, drying, obtain finished product.
Foregoing synthetic leather production is with one side leaching material technique, and the liquid level of the polyurethane material in the step b is located at roll
Below the center of circle of side at 1cm position.
Foregoing synthetic leather production is with one side leaching material technique, and the thickness of one layer of polyurethane material of painting in the step d is
Being solidified as in 0.8mm~1.2mm, the step e is solid into water-setting, and the time is 8min~12min；Washing in the step f
DMF is removed for washing, washing temperature is 25 DEG C~30 DEG C；Drying time in the step g is 5min~10min, drying temperature
Spend for 130 DEG C~150 DEG C.
The device expected constructed by technique, including hopper, the two ends point of hopper are soaked with one side according to foregoing synthetic leather production
It is not provided with feed roller and discharge roller, hopper and is provided with polyurethane material；5 are set side by side between feed roller and discharge roller to roll
Top between roller, adjacent two rolls is provided with guide roller；The side center of circle of the roll is located at the liquid level of polyurethane material
Top.
In foregoing device, the public tangent plane of the roll and feed roller is vertical plane, and the public tangent plane of roll and discharge roller is
The public tangent plane of vertical plane, roll and guide roller is also vertical plane.
In foregoing device, the distance between liquid level and roll of the polyurethane material are 1cm.
Compared with prior art, the present invention devises a kind of synthetic leather production one side leaching material technique and device, by rolling
Roller immerses base fabric in polyurethane material, and the liquid level of polyurethane material is located at below the center of circle of roll side, and circulates 5 leachings of progress
Material, so that polyurethane material can be penetrated into the tissue of base fabric, forms infiltration interlaced plies, positive polyurethane is then carried out again
Expect coating, it is possible to increase peel strength, improve its durability；Meanwhile, by setting the liquid level of polyurethane material to be located at roll side
Below the center of circle, the one side leaching material of base fabric can be carried out, infiltration interlaced plies can not only be made to be respectively positioned on the front position of base fabric, it is convenient
Bonded with polyurethane material coating, additionally it is possible to prevent the base fabric back side to be stained with polyurethane material, the synthetic leather of one side imitation leather can be formed, made
Obtain product and have the comfortableness (nexine) of cloth and the texture (top layer) of leather concurrently.In addition, the present invention is also by the liquid level of polyurethane material
At the position of 1cm below the center of circle of roll side, leaching charge level product can be ensured while one side leaching material is ensured, production is improved
Speed；Also it is vertical plane by the public tangent plane of roll and guide roller, can further ensure that base fabric one side leaching material when soaking material, prevent
Only the tow sides of base fabric are soaked with polyurethane material.Therefore, the present invention can not only improve peel strength, also with durability
The good, advantage that comfortableness is good and texture is good.
