New spunlace nonwoven material and its production process for soft and weather-resistant building structures

Abstract

The invention discloses a novel spunlaced nonwoven material for a soft weather-proof building structure and a production process for the material, and belongs to the technical field of textile materials. The production process comprises the following steps: firstly, feeding polyester fibers into a long curtain, a horizontal opener, a big cabin cotton blending box and a fine opener in sequence; secondly, performing layering and carding by a carding machine I and a carding machine II, and feeding the raw materials processed through the carding machine I into a cross lapping machine and a traction machine in sequence; thirdly, stacking the raw materials processed through the traction machine and the raw materials processed through the carding machine II, performing a spunlacing process, a drying process, an online detection process and a winding process in sequence, and obtaining polyester spunlaced nonwoven materials; finally, putting a PE (polyethylene) microporous breathable film between the two layers of polyester spunlaced nonwoven materials, performing a hot-rolling-bonding process, and obtaining the finished novel spunlaced nonwoven material. The novel spunlaced nonwoven material for the soft weather-proof building structure has the characteristics of good waterproofness, strong breathability, no fiber falling phenomenon, good hand feel, and high and uniform strong force in each direction.

Description

technical field [0001] The invention discloses a soft and weather-resistant building structure spunlace nonwoven new material and a production process thereof, which belong to the technical field of textile materials. Background technique [0002] Building materials are one of the necessary components of a building. They can protect the building, such as waterproof and leakproof, so that the life of the building can be guaranteed. Building base materials mainly include modified asphalt waterproof materials, PVC waterproof materials, non-woven fabrics, etc. Compared with other types of building materials, non-woven products have unique advantages such as softness, good waterproof, good air permeability, and less fiber shedding, and are an ideal building substrate. [0003] However, with the development of science and technology and the improvement of people's living standards, people's requirements for building materials are also increasing, including requirements for houses...

AI Technical Summary

Problems solved by technology

Through the research on the existing non-woven fabrics on the market, it is found that its waterproof and anti-seepage performance, all-directional strength, fiber shedding, hand feeling and other aspects still need to be improved.
