Problems solved by technology

However, in cold weather, this type of product cannot be used due to wearing non-conductive gloves, which greatly limits the use environment of the product. Therefore, it can be predicted that the market demand for synthetic leather with low resistivity as conductive glove leather will be considerable. huge
[0003] However, the current method is to add conductive materials such as carbon black to wet-process polyurethane, and then impregnate them into the base fabric. Stable, and there will be black spots on the surface of the base cloth

Abstract

The invention discloses conductive superfine fiber suede leather and a preparation method thereof. On one hand, carbon fiber modified PA6 resin is added in spinning, so that a carbon fiber conductivenetwork is formed in a suede leather fiber matrix and the conductive effect is improved; and on the other hand, by dipping citrate sol finishing liquid of transition metal, a large amount of conductive transition metal fine particles are adsorbed in microfiber leather micropores, so that the property of contact between the carbon fiber conductive network covered by an insulating polyurethane partand the surface conductive fine particles is greatly improved, the conductive performance of a product can be remarkably improved, and the requirements of conductive glove leather are met.

Description

technical field [0001] The invention relates to a superfine fiber suede leather, in particular to a conductive superfine fiber suede leather and a preparation method thereof, and belongs to the field of the superfine fiber suede leather. Background technique [0002] With the development of science and technology, capacitive touch screen products have become popular all over the world. With the further development of this trend, touch control, a new mode of human-computer interaction, is widely used in all aspects of life. However, when the weather is cold, such products cannot be used due to wearing non-conductive gloves, which greatly limits the use environment of the products. Therefore, it can be predicted that the market demand for low-resistivity synthetic leather as conductive glove leather will be quite high. huge. [0003] However, the current method is to add conductive materials such as carbon black into wet-process polyurethane, and then impregnate it into the b...
