Filter cloth is a commonly used filtering medium in industrial production, and its weaving type and method have a significant impact on the filtration effect and service life. This article will provide a detailed introduction to the types and methods of weaving filter cloth to help readers better understand this field.
Types of woven filter cloth
(1) Woven filter cloth
Machine woven filter cloth is woven from vertically arranged warp and weft threads through a complex interweaving process. The gap between the longitude and latitude lines can accommodate and intercept impurities, thereby achieving filtering function. Machine woven filter cloth has high filtration accuracy and strong tensile strength, therefore it has good application effects in high temperature, high pressure, and highly corrosive environments.
(2) Non woven filter cloth
Non woven filter cloth is made through non-woven technology, and its fiber raw materials can be various materials from natural fibers to synthetic fibers. The structure and performance of non-woven filter cloth are similar to those of woven filter cloth, but due to its irregular fiber arrangement, its filtration efficiency and tensile strength are slightly lower than those of woven filter cloth. Non woven filter fabrics are widely used in the field of low precision filtration due to their advantages such as low cost, lightweight and softness, and easy cleaning.
Classified by fiber material
(1) Natural fiber filter cloth
Natural fiber filter cloth is made from natural fibers such as cotton, linen, wool, etc. Natural fiber filter cloth has the advantages of good moisture absorption, good breathability, non-toxic and odorless, but its high temperature resistance is poor and it is easily corroded by chemical substances. Suitable for general filtering and coarse filtering.
(2) Synthetic fiber filter cloth
Synthetic fiber filter cloth is made from synthetic fibers such as polyester fibers, polypropylene fibers, etc. Synthetic fiber filter cloth has the advantages of high temperature resistance, corrosion resistance, and wear resistance, and is suitable for fine filtration in environments with high temperature, high pressure, and strong corrosiveness.
Weaving method
1. Woven weaving is composed of yarns with intersecting relationships. A fabric composed of yarns with intersecting relationships, such as two-dimensional or three-dimensional fabrics. Woven fabric yarns are divided into warp and warp directions (vertical on the loom); Weft yarn, weft direction (transverse direction on the loom).
2. Knitting is composed of yarns that have a winding relationship. A fabric composed of yarns with winding relationships, such as warp knitting and weft knitting.
3. Non woven is composed of yarns and fibers that are connected together. Textiles made from textile fibers through bonding, fusion, or other chemical or mechanical processes. Non woven fabric, a type of fiber cloth. Also known as nonwoven cloth or non-woven fabric.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
