Abstract

The invention discloses ultra-fine fiber suede leather for a capacitive sensing touch screen and a manufacture method of the ultra-fine fiber suede leather. The ultra-fine fiber suede leather for the capacitive sensing touch screen comprises the following ingredients of percentage by weight: 46 to 54 percent of polyurethane resin, 0.16 to 6 percent of carbon black and 45 to 52 percent of nylon. Conducting function masterbatch is added into the spinning, so the sea-island fiber has the conducting function, the prepared ultra-fine fiber suede leather is soaked with conducting finishing agents, the conducting performance of suede glove leather is enhanced, the conductivity of the prepared conducting type ultra-fine fiber suede glove leather is between 10<-4> s / m and 10<-9> s / m, in addition, the inner layer and the outer layer are both conductive, the ultra-fine fiber suede leather is particularly suitable for touch screen electronic products, and meanwhile, good characteristics of high intensity, ventilation, moisture permeability, wear resistance, corrosion resistance and the like of the ultra-fine fiber suede glove leather are maintained.

Description

technical field [0001] The invention relates to a superfine fiber polyurethane suede leather and a preparation method thereof, in particular to a superfine fiber polyurethane suede leather used for touch screen sensing. Background technique [0002] With the update of technology trends and the introduction of Apple's Iphone in 2007, capacitive touch screen products began to enter the stage of history, and then touch screens were popularized in the field of new consumer electronics very quickly. 75% of the total mobile phone shipments, but with it comes the problem of keeping warm in winter with capacitive touch screen products. Since capacitive touch screen products (non-conductive) cannot be operated with gloves, it is very cold to use touch screen products outdoors. Especially in South Korea at a high latitude, and at the other end of the populous country - China, there are also many people who are troubled and helpless by this.
