Abstract

The invention discloses a preparation method of high-shrinkage orange slice type double-component spunbonded spunlace microfiber leather base cloth. The method comprises the following steps of firstly, adding a hot air device and a fiber crimping device in a double-component spunbond/spunlace production line, and then spinning double-component composite fibers into a web; conveying the fiber web into the hot air device for thermal shrinkage treatment, and enabling the double-component composite fibers to generate a split trend by utilizing thermal shrinkage of high-shrinkage components in the double-component composite fibers; enabling the double-component composite fibers to be split and mutually entangled through a spunlace technology; conveying the double-component composite fibers into a fiber crimping device, and performing shrinkage and crimping treatment on non-woven cloth by utilizing the fiber crimping device, so that the high-shrinkage components are completely shrunk and crimped, and the double-component spunbonded spunlace microfiber leather base cloth is obtained. The method is simple in technological process and low in production cost and energy consumption, green and clean preparation of the microfiber leather base cloth can be achieved through a one-step method, and the prepared hollow orange slice type double-component spunbonded spunlace leather base cloth has the characteristics of being compact, soft, stiff and smooth and full in hand feeling.

Description

technical field [0001] The invention relates to the field of non-woven fabrics, in particular to a preparation method of a high-shrinkage segmental orange-shaped two-component spun-bonded spunlace microfiber leather base cloth. Background technique [0002] The pie-shaped ultrafine fiber nonwoven fabric prepared by the two-component spunbond spunlace nonwoven technology solves the environmental pollution problem caused by the sea-island fiber dissolving and opening the ultrafine fiber nonwoven fabric. The process is simple and can be used The preparation of light, high-strength microfiber nonwoven fabric can be widely used in the fields of microfiber leather, filtration, wiping, etc., especially in the field of microfiber leather, which can realize the green and clean preparation of microfiber leather base cloth. Application No. 201710026839.6 uses hollow segmented orange-shaped two-component spunbond spunlace nonwoven fabric as the base fabric, and prepares spunbond filamen...
