Abstract

The invention discloses a color antistatic superfine fiber suede material and a preparation method thereof. The preparation method comprises the following steps: (1) blending nylon 6, low density polyethylene and nano SnO2 to prepare antistatic indefinite-island sea-island short fibers; (2) preparing the conductive indefinite-island sea-island fibers into a conductive non-woven fabric; (3) dippingthe conductive non-woven fabric in a polyurethane conductive solution to prepare conductive base cloth containing polyurethane; (4) extracting low-density polyethylene out of the base cloth by usingtoluene to prepare a semi-finished product of superfine fiber suede leather for a capacitive sensing touch screen, and carrying out after finishing; and (5) soaking the semi-finished product in transition metal oxide sol, and carrying out padding and drying to obtain the color antistatic superfine fiber suede material. According to the preparation method provided by the invention, the conductivityof suede leather is enhanced; the conductivity of prepared conductive superfine fiber suede leather is between 10<-3>s / m and 10<-8>s / m, and both the inner layer and the outer layer are conductive; and meanwhile, the excellent characteristics of superfine fiber suede glove leather, such as high strength, air permeability, moisture permeability, abrasion resistance, and corrosion resistance, are maintained.

Description

technical field [0001] The invention relates to a preparation method of a colored antistatic ultrafine fiber suede material, in particular to a colored polyurethane ultrafine fiber suede used in the field of antistatic. Background technique [0002] Static electricity is an objective natural phenomenon, which can be produced in many ways, such as contact, friction, peeling and so on. Electrostatic protection technology, such as electrostatic hazards in the electronics industry, semiconductor, petroleum industry, weapon industry, textile industry, rubber industry, and aviation and military fields, seeks to reduce the losses caused by static electricity. [0003] The antistatic microfiber suede. At the same time overcome the defects of the prior art, Chinese patent application (application number 201210331257.6) discloses a kind of superfine fiber suede for capacitive sensing touch screen and its manufacturing method, by adding carbon black in spinning to make conductive mate...
