Non woven fabric is a new type of textile material that combines fibers or sheets through mechanical, chemical, or thermal techniques to form a fabric like structure. Non woven fabric is the third major category of new materials corresponding to textiles. Due to its flexibility, breathability, resistance to shedding, softness, corrosion resistance, wear resistance, fast water absorption, washing resistance, easy drying, and relatively low price, it is widely used in medical supplies, household products, clothing, footwear, automotive interior, agriculture, home bathroom and other fields.
The production process and standards of non-woven fabrics are key factors that directly determine their quality and application areas. The production process of non-woven fabric mainly includes fiber selection, pretreatment, spunbond, perforation, fixed width, swing saw, hot pressing, shaping and other processes. Firstly, suitable raw materials should be selected for the production of non-woven fabrics. Common raw materials include polyester, polypropylene, acrylic, etc. Then, the selected fibers are subjected to pre-treatment processes such as cleaning and drying to ensure the quality of the raw materials. Next, the fibers are fed into a spunbond machine for spunbond treatment, and then punched through holes to make the non-woven fabric breathable. Subsequently, the non-woven fabric was formed using equipment such as fixed amplitude and swing saw., Through post-processing such as hot pressing and shaping, non-woven fabrics are made to have the required characteristics.
In the production process, the finished product standards for non-woven fabrics are also crucial. Usually, the standards for non-woven fabrics include indicators such as product weight, thickness, breathability, strength, elongation, and fracture strength. For example, according to specific application requirements, the weight of non-woven fabric products is generally between 10-300g/m2. Breathability is an important indicator of non-woven fabrics, and the better the breathability, the wider the application range of non-woven fabrics. In addition, the strength and elongation of non-woven fabrics are also very important parameters, which directly affect the quality and service life of the product.
In addition, the production process and standards of non-woven fabrics are also influenced by national laws and regulations. The country has strict quality standards and production processes for non-woven fabrics in special industries such as medical non-woven fabrics, mask non-woven fabrics, and sanitary napkins non-woven fabrics. Therefore, non-woven fabric manufacturers should strictly comply with relevant regulations during the production process to ensure the quality and safety of non-woven fabric products.
Overall, the production process and standards of non-woven fabrics are the key factors determining their quality and application areas. Non woven fabric manufacturers should continuously improve their production process level, pay attention to product quality control, comply with national regulations, and ensure the quality and market competitiveness of non-woven fabric products. I hope that with the continuous progress of technology and the improvement of industry standards, non-woven fabric products will be more widely used in various fields.
