Embodiment 1

[0039] Embodiment 1: a kind of manufacture method that can release the synthetic leather of negative ion is as follows:

[0040] A, 14 parts (by weight) of PA6 slices and 6 parts of nano tourmaline powder with a particle size of 50 nanometers are mixed and melted and extruded to obtain a PA6 master batch containing nano tourmaline powder, and then 3 parts of PA6 tourmaline powder master batch with 42 pieces of PE slices and 55 pieces of PA6 slices are combined evenly, and then the mixed materials are sent to the screw extruder for melt blending and spinning to form sea-island fiber filaments with PA6 as the island and PE as the sea. The density is 17-20 dtex, the filament is drawn under a water bath at 65°C, the elongation is 3.0-3.5 times, the final linear density is 5.5-7.0 dtex, and the strength is above 3.0 cN / dtex, Then perform mechanical crimping and cut it into short fibers with a length of 50 mm;

[0041] B. Processing of non-woven fabrics: Sea-island staple fibers ar...

Embodiment 2～4

[0047] In embodiment 2~4, adopt the parameter shown in the following table to replace the corresponding parameter in embodiment 1, all the other conditions are with embodiment 1;

Abstract

The invention relates to synthetic leather capable of releasing negative ions and a preparation method of the synthetic leather. The synthetic leather includes a matrix layer, a polyurethane inner coating layer and a polyurethane surface layer, wherein the matrix layer consists of PA6 superfine fibers; the polyurethane inner coating layer is formed by being dipped in polyurethane solution through a wet method and solidified on the surface of the matrix layer; the polyurethane surface layer is prepared from a polyurethane sizing agent through a dry method and the polyurethane surface layer is adhered with the polyurethane inner coating layer through polyurethane adhesive resin; and the PA6 superfine fibers contain nanometer tourmaline powder. The method comprises the following steps: manufacturing sea-island fiber, processing non-woven, sizing and planishing, steeping using wet process, extracting with decrement, drying and sizing, mellowing, and shifting membrane in a dry method. The synthetic leather has the function of releasing negative ions and is especially suitable for producing high-grade synthetic leather such as automobile inner decoration leather with a health-care function, and the like.

Description

technical field [0001] The invention relates to a synthetic leather and a manufacturing method thereof. More specifically, the present invention relates to a synthetic leather capable of releasing negative ions and a manufacturing method thereof. The synthetic leather is especially suitable for manufacturing automobile interior leather. Background technique [0002] With the rapid development of my country's automobile industry, the demand for automotive interior leather is also increasing year by year. Genuine leather has always been the first choice for high-end automotive interior leather, but due to the increasing scarcity of genuine leather resources and higher environmental protection requirements, genuine leather automotive leather is not the trend of future automotive interior leather. Artificial synthetic leather will play an important role in the future of automotive interior leather. Due to the late start of the domestic auto industry, the design and material deve...
