Non-woven fabric processing flow

The scientific name of non-woven fabric is non-woven fabric, also known as non-woven fabric. Non-woven fabric is a kind of fabric that does not need to be spun and weaving. In the non-woven fabric processing and production process, the textile short fibers or filaments are oriented or randomly arranged to form a web structure, and then mechanical, thermal bonding or chemical Reinforced by other methods. Non-woven fabric breaks through the traditional textile principle, and has the characteristics of short process flow, fast production speed, high output, low cost, wide use, and multiple sources of raw materials. 1. Spunlace non-woven fabric processing: it is to spray high-pressure fine water stream onto one or more layers of fiber web to make the fibers entangled with each other, so that the fiber web can be strengthened and possess a certain strength. 2. Heat-bonding non-woven fabric processing: refers to adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and then the fiber web is heated, melted and cooled to reinforce into a cloth. 3. Pulp air-laid non-woven fabric processing: it can also be called dust-free paper and dry paper-making non-woven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglomerate the fibers on the web curtain, and then reinforce the fiber web into a cloth. 4. Wet-laid non-woven fabric processing: the fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time to form a fiber suspension slurry, which is transported to the web forming mechanism, and the fibers are in a wet state. Down into a net and then reinforced into a cloth. 5. Spunbond processing: After the polymer has been extruded and stretched to form continuous filaments (using chemical fiber spinning), the filaments are laid into a net, and the fiber net is then bonded by itself. Methods such as bonding, thermal bonding, chemical bonding or needle punching can reinforce the web to form a non-woven fabric. The high polymer is spun, drawn and laid into a net. 6. Meltblown non-woven fabric processing: The melt-blown non-woven process uses high-speed hot air flow to stretch the polymer melt stream extruded from the die nozzle hole, thereby forming ultra-fine fibers and collecting On the condensed net curtain or roller, at the same time it adheres to itself to become a melt-blown non-woven fabric. 7. Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric. The needle-punched non-woven fabric uses the piercing effect of a needle to reinforce the fluffy web into a cloth. The non-woven fabric industry has produced a series of special functions with its short process, high quality, high yield, low consumption and low cost. It has occupied part of the textile market and created its own unique market, especially the disposable products market. The promising industry non-woven woven fabric can be traced back to 7000 years ago. Modern non-woven fabrics really started with needle punched non-woven fabrics born in the UK in 1870; meltblown fabrics were produced in the United States in 1951; spunbond fabrics were invented in the United States in 1959. Spunbond non-woven fabric processing and production process: raw material (PP+masterbatch) input (mixing) → screw melting → filtration → metering pump metering → melt distribution → extrusion molding (spinning) → cooling and drawing → splitting and laying → Hot rolling bonding → winding → slitting meltblown non-woven fabric processing production process: raw material (PP + masterbatch) input (mixing) → screw melting → filtration → metering pump metering → die spinning → hot air drawing → Chengwang Fujian Plastic Industry Co., Ltd. is a professional non-woven fabric processing, design, production, and direct sales enterprise.
