A kind of conductive microfiber leather and its preparation method and equipment

Abstract

The invention discloses conductive microfiber leather as well as a preparation method and equipment thereof. The preparation method of the conductive microfiber leather comprises the following steps:1) activating a microfiber staple fiber; 2) impregnating graphene oxide; 3) preparing sulfur-graphene / microfiber staple fiber; 4) impregnating a faintly alkaline strong reducing agent; 5) desulfurating and reducing; 6) washing; 7) preparing a non-woven fabric; 8) preparing the microfiber leather. In addition to the conventional production line for preparing the microfiber leather through the microfiber staple fiber, the equipment further comprises an opener and a microfiber staple fiber processing tank, the microfiber staple fiber processing tank takes the shape of a funnel bucket, a porous filter plate is arranged at the bottom of a funnel, and a cake shaped extruding machine is arranged at the top of the funnel. The graphene is bounded with the microfiber staple fiber through the chemical bond, the binding force is firm, the graphene is more evenly distributed on the surface of the microfiber staple fiber, the electrical conductivity of the synthesized conductive microfiber leather is better, and the tinting strength of the synthesized conductive microfiber leather is strong.

Description

technical field [0001] The invention belongs to the technical field of superfine fiber synthetic leather, and in particular relates to a conductive superfiber leather and a preparation method and equipment thereof. Background technique [0002] Microfiber synthetic leather is the direction of future development of synthetic leather. Because it uses a three-dimensional network structure of non-woven fabric as the base, and has an open-pore structure of polyurethane mesh and nylon bundle structure, it truly simulates the shape of natural leather and has the most similar properties to natural leather. [0003] With the improvement of living standards, people have more and more requirements for fabrics. For example, fabrics for high-speed train seats have high requirements for flame retardancy, dripability, and smoke density; fabrics for conductive gloves have high requirements for wear resistance and conductivity; and fabrics for health care products For fabrics, there are sp...
