Abstract

The invention relates to automobile interior trim non-woven with the negative ion function and a production method thereof. The method comprises the following steps: selecting natural fibrilia and low melting point fiber, weighting, mixing, opening, air-laying, adding negative ion finishing agent, hot-rolling and reinforcing, performing impregnation and coating, moulding for forming, and drying to prepare the finished product, wherein the negative ion finishing agent is prepared from 100 parts of deionized water, 2-7 parts of dispersant and 6-12 parts of superfine tourmaline power through ultrasonic agitation and dispersion. The thermoplasticity of low melting point fiber is utilized to fix the negative ion finishing agent on a mesh. 125-175g / m<2> of negative ion finishing agent are on the non-woven and the amount of release of negative ions is 3500-8000 on every square centimeter. The product is used in parts such as automobile roofs, back bed-plates, luggage compartment door interior trims and clothes trees and can automatically release negative ions for a long time. The product can also be used in the interior trims and decorations of vehicles such as trains, planes and ships. The product can improve the air quality in an automobile on a trip and regulate the human microcirculation.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabric production with hemp fiber as the base material and low-melting-point fiber as the auxiliary material, and relates to the functional finishing technology of the non-woven fabric. At the same time, it relates to a highly dispersed liquid capable of producing negative ion chemicals and its preparation technology. Background technique [0002] With the development of society, automobiles, trains, airplanes, ships and other means of transportation have become more and more popular in people's lives, especially automobiles, which have gradually become an essential travel tool in people's lives. This requires that the quality of life inside the car can be close to people's hearts. , more consideration of human health. For automotive textiles, there are strict requirements on air permeability, comfort, aesthetics, and odor. However, the space inside the car is limited, and the cause of air poll...
