Abstract

The invention discloses conductive polyurethane superfine fiber suede leather and a preparing method thereof. The preparing method comprises the steps of drying superfine fiber suede leather at a temperature in a range of 80 DEG C to 140 DEG C for 5 to 30 minutes, and impregnating the superfine fiber suede leather in a conductive solution for 5 to 50 seconds, wherein, the liquor ratio is between 1:1 and 1:20; and drying the impregnated solution at a temperature ranging from 80 DEG C to 140 DEG C for 5 to 30 minutes to obtain the conductive polyurethane superfine fiber suede leather. According to the conductive polyurethane superfine fiber suede leather and the preparing method thereof, preparing processes are all basic processes of synthetic leather businesses, no special requirements are asked for devices and process conditions, and the prepared conductive polyurethane superfine fiber suede leather can be applied to products of electronic touch screen gloves and the like and has enormous market prospects.

Description

technical field [0001] The invention relates to a polyurethane superfine fiber suede and a manufacturing method thereof, in particular to a conductive polyurethane superfine fiber suede and a manufacturing method thereof. Background technique [0002] In recent years, as the iPhone, iPad and other products of the American Apple Company have swept the world, it has triggered the popularity of touch-screen electronic products. At present, there are mainly two types of touch screens on the market: resistive touch screens and capacitive touch screens. Resistive touch screen has the advantages of simple working principle and low power consumption, but its disadvantages are long response time, short service life, low light transmittance and poor scratch resistance. The capacitive touch screen has the characteristics of fast response time, long service life and high light transmittance, and is currently the mainstream touch screen. During the use of the capacitive touch screen, t...
