Problems solved by technology

However, due to the different shrinkage and expansion coefficients of the non-woven fabric on the surface and the glass fiber mesh cloth in the middle, after the asphalt is attached and cooled, the surface non-woven fabric and the glass fiber mesh cloth tend to be bonded and cracked and separated, thus losing The performance of this material application
After the material is made, the thickness is relatively large, so it is not suitable for occasions that require high thickness of non-woven fabrics, and the production cost is high

Embodiment Construction

[0015] Below in conjunction with accompanying drawing, the invention is further described:

[0016] Firstly, the raw materials of polyester staple fiber are opened and loosened into filaments that are easy to card, and then combed. Many filaments are carded into cotton webs. Sometimes in order to increase the strength, it is necessary to combine two or three different polyester staple fibers. It is opened, then blended and carded into a web. After the cotton net is obtained, the net is laid, that is, the cotton net is repeatedly overlapped, and the number of overlapping layers is increased, generally four layers, or more layers, depending on the thickness and strength of the required product, the greater the required thickness and strength , the more overlapping layers are required.

[0017] The overlapping cotton nets are needled by the needling machine. Generally, four rows of needling machines are used for needling in sequence. The needles are fixed on the needle plate. T...

Abstract

The invention discloses a technology for manufacturing strong non-woven cloth, which is characterized by folding four layers of non-woven cloth, needling to obtain needled non-woven cloth, additionally paving fiberglass gridding cloth on the surface of the needled non-woven cloth, and interweaving the fiber of the fiberglass gridding cloth and the fiber of the non-woven cloth together in a needling way. According to the technology, not only is the overall strength of a material improved, but also the separation of the non-woven cloth away from fiberglass grids is prevented; therefore new type non-woven cloth which is strong in tensile force and is closely connected into a whole is manufactured.

Description

technical field [0001] The invention relates to the field of non-woven fabric production, in particular to a production process of strong non-woven fabric. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of qualitative or randomly arranged fibers. They have many advantages such as moisture resistance, breathability, flexibility, and light weight. They are a new generation of environmentally friendly materials and have many important applications in industry or life. For example, the linoleum used for waterproofing in the construction industry is made of non-woven fabric as a carrier with asphalt attached to it. However, in the actual production process of linoleum, the non-woven fabric is simply soaked in asphalt. During the stretching process, due to the insufficient strength of the non-woven fabric, the non-woven fabric will break and the work will be interrupted. In order to increase the tensile force of the non-woven fabric...
