[0017] The present invention provides a kind of preparation method of spunbonded filament pie-shaped superfiber leather, it is characterized in that this preparation method comprises the following steps:

[0018] 1) Preparation of two-component ultrafine fiber spunbonded spunlace nonwoven fabric: firstly, the two kinds of polymer slices are respectively introduced into the drying tower for pre-crystallization and drying treatment, extruded and melted by a screw extruder, melt filter After being filtered, it enters the spinning box; then, the segmented segment is used to form a web by drawing and spinning on a two-component spunbond equipment, and finally the fiber web output by the web forming machine enters the spunlace area after pre-humidification. Under the pressure of the water flow, the fibers are opened and entangled together; after drying, trimming, and winding into rolls, a two-component ultrafine fiber spunbond spunlace non-woven fabric (non-woven fabric for short) is...

Abstract

The invention discloses a preparation method for spun-bonded filament orange petal-type superfine leather. The preparation method comprises the following steps: first, preparing two-component orange petal-type composite filament fibres by adopting a spun-bonding method, paving a net on a net curtain, and strengthening through spunlace to obtain a base fabric of a non-woven fabric; then, preparing a water-based polyurethane surface layer and a foaming layer on release paper, and preparing a water-based polyurethane bonding layer on the base fabric; finally, adhering the surface layer and the foaming layer to the bonding layer of the base fabric to obtain the spun-bonded filament orange petal-type superfine leather. Compared with the prior art, the filament spunlace non-woven fabric is spun-bonded by adopting two-component superfine fibres, and water-based polyurethane resin is combined, so that the problems of organic wastewater caused by a methylbenzene reduction or alkaline reduction process and DMF (Dimethyl Formamide) solvent pollution caused by a solvent type production system in the existing superfine fibre synthesis leather industry are effectively solved; a superfine fibre synthesis leather production line which is simple in process, green, environment-friendly and pollution-free is formed.

Description

technical field [0001] The invention relates to the technical field of superfine fiber synthetic leather, in particular to a preparation method of spun-bonded filament orange segment superfiber leather. Background technique [0002] As the latest generation of synthetic leather products, microfiber synthetic leather has excellent resilience, softness, imitation, and air permeability. It is replacing genuine leather and ordinary synthetic leather to meet the demand for high-end products in domestic and foreign markets. , reflecting the main direction of synthetic leather technology development. [0003] At present, the preparation technology of ultrafine fiber synthetic leather is relatively mature, but serious pollution occurs in the production process of ultrafine fiber synthetic leather, which prevents the further development and application of ultrafine fiber synthetic leather. The reasons for the pollution are: (1) Most of the sea-island microfibers used to make superfi...
