Yarn is a continuous strip composed of textile fibers with certain mechanical properties, fineness, and flexibility; Filter cloth is woven from yarn; There are two types of yarns, one is long filament fibers that have not undergone any processing or have been combined, twisted, and deformed; Another type is processed short fibers.
Distinguish by yarn structure and shape:
1) Short fiber
a. Single yarn. Formed by processing short fiber warp yarn;
b. Stock line. Made by combining and twisting two or more single yarns;
c. Expanded yarn. Made by mixing low shrinkage and high shrinkage acrylic fibers in a certain proportion;
d. Twist the thread. Made by twisting single yarns of two or more fibers or colors together.
2) Long fiber
a. Monofilament. A yarn composed of a single filament fiber;
b. Double silk. Combining two or more single filaments together;
c. Twisted silk. Woven yarn is formed by twisting;
d. Composite twisted yarn. Twisted yarn is combined and twisted one or more times to form a composite twisted yarn;
e. Blended fibers. Made by mixing two or more types of filament fibers.
The filter cloth woven from the above yarns, Bolian Filter has single-layer monofilament, double-layer monofilament, double-layer monofilament, double-layer multifilament, single-layer multifilament, single-layer multifilament and other filter cloths. Its application fields include chemical industry, pharmaceuticals, catalysts, potassium fertilizer, coal ash water, desulfurization and other fields.
Simulation and experimental study on the purification performance of filter cloth, filter media, and filter materials
