Problems solved by technology

The antistatic automotive interior nonwoven fabric prepared by mixing a certain amount of conductive fibers into the raw materials has the characteristics of good antistatic effect and long-lasting, but the manufacturing cost is high, and due to the addition of a certain amount of conductive fibers, the obtained The fiber web is a collection of conductive fibers and non-conductive fibers, which changes the original performance of the fiber web. It is different from the fiber web composed of non-conductive fibers in performance, so there are certain restrictions on the range of product applications.

[0020] (3) Preparation of electrospun conductive fibers

[0021] Before the air-laid fiber web enters the fiber web reinforcement process, an electrospinning device is installed, a spinneret is installed above the fiber web, and a grounded electrode plate is installed below the fiber web. The raw material of the spinning solution It is a compound of polyaniline polymer or polyaniline polymer. Connect the spinning solution to the positive pole of the high-voltage power supply, connect the grounded plate to the negative pole of the high-voltage power supply, and form a high-voltage electric field between the spinneret and the grounded plate. The spinning solution extruded from the spinneret is stretched into nanometer-scale ultrafine fibers under the action of a high-voltage electric field, and the fiber diameter is less than 1000 nanometers, which are superimposed on the fiber web to form a combined fiber web. Because the composite of polyaniline polymer and polyaniline polymer...

Abstract

The invention relates to a method for manufacturing an antistatic automotive interior non-woven fabric and belongs to the technical field of textile. The method comprises the processes of preparation before net formation of the non-woven fabric, air laying, fiber web strengthening and post processing. The manufacturing method comprises the following steps that before a fiber web subjected to air laying enters the fiber web strengthening process, spinning solution extruded from an antistatic spinning spinneret is drawn into ultrathin conducting fibers under the action of a high voltage electrostatic field; overlapping the ultrathin conducting fibers on the surface of the fiber web to form a combined fiber web; and then by the fiber web strengthening process, manufacturing the antistatic automotive interior non-woven fabric. According to the invention, the defects of easiness for volatilization and poor adaptability which are caused by use of an antistatic agent are overcome; the prepared antistatic automotive interior non-woven fabric has a good and durable antistatic effect; the physical mechanical performance of an original fiber web is not changed; the fibers in the fiber web is distributed in a three-dimensional manner; longitudinal and transverse strength difference of a product is small; and the method is suitable for producing the antistatic automotive interior non-woven fabric.

Description

technical field [0001] The invention relates to a method for manufacturing an antistatic automobile interior trim nonwoven fabric, which belongs to the technical field of textiles. Background technique [0002] In recent years, with the rapid development of my country's automobile industry, automobile textiles and their fiber materials have also developed accordingly, with the number constantly expanding, the variety gradually increasing, and the quality improving day by day. Textiles for automotive interiors mainly include woven fabrics, knitted fabrics, nonwovens and high-performance fiber composites. Compared with woven fabrics and knitted fabrics, non-woven fabrics are easier to engineer and can be deeply molded to meet the requirements of complex surface shapes for various interior parts. At the same time, the thickness and hardness of materials can be adjusted according to the requirements of automobile manufacturers. Indicators are personalized. Nonwovens can not on...
