Problems solved by technology

[0005] Due to the existing wet-laid spunlace technology, the fabric base fabrics currently available in the market have large and unstable shrinkage, extremely low tear strength, and difficult deep processing of finished products , only used in a small range such as medical, sanitary napkins and facial masks, with different added values
It is basically impossible to perform post-processing such as dyeing to achieve wearing performance, and the application of high-end clothing fabrics is almost zero

Abstract

A method for manufacturing artificial leather base fabric belongs to the manufacturing technique of non-woven fabrics and comprises the following steps: dispersing superfine fibers in water to manufacture a superfine fiber turbid liquid; uniformly covering the superfine fiber turbid liquid on the surface of an inclined wire through paper-making equipment; transmitting a knitted base fabric into the paper-making equipment; absorbing a fiber web on the surface of the knitted base fabric; taking into spunlace equipment to achieve high-pressure water flow spray treatment to enable the fiber web to be intertwined with the surface of the base fabric; reversing the processed knitted base fabric and a superfine fiber compound with the surfaces facing downwards, and placing the reversed fabric and the superfine fiber compound in an unwinding device in front of the paper-making equipment; uniformly covering the superfine fiber turbid liquid on the surface of the inclined wire through the paper-making equipment; repeatedly reversing, covering and spunlacing to plunge the artificial leather into a hot water storage tank through the base fabric to achieve weft-wise free contraction; reducing pressure, dehydrating and drying to obtain the finished product of artificial leather basic fabric. The finished product has a certain strength and flexibleness and can be used for high-grade clothes fabric.

Description

technical field [0001] The invention belongs to the manufacturing technology of non-woven fabrics, and relates to a manufacturing method of artificial leather base cloth. Background technique [0002] The non-woven processing of ultra-fine composite fibers generally adopts the process of carding into a web, needle punching and spunlace, but a combination of wet process and spunlace is also used. [0003] Direct needle punching and hydroentangling generally require the fibers to be fed to a carding machine. However, if the ultrafine fiber is directly fed into the opening and carding machine, the damage to the fiber is too great and it is difficult to process, and the fiber is more likely to be damaged and broken by needle punching. Therefore, it is generally fed in the form of composite fibers (or blended fibers) that have not been separated, and then dissolved into a component after making it into a non-woven fabric, so that the fibers are not damaged. [0004] For dire...
