Polyester bolting cloth is a high-performance industrial mesh fabric, primarily made from polyester monofilament woven through specialized techniques. It features high tensile strength, low elongation, chemical resistance, heat resistance, and good air permeability. This makes it a versatile solution for various applications across industries, including screening, filtering, and printing, often replacing traditional stainless steel wire cloth. Polyester bolting cloth is characterized by its precise weave, smooth surface, and exceptional dimensional stability. It excels in applications demanding accurate particle separation, durability, and resistance to chemicals and abrasion. Compared to stainless steel wire cloth, polyester bolting cloth is often lighter, more flexible, and less prone to blinding or clogging.

Petter supplies two types of bolting cloths: polyester bolting cloth and stainless steel woven wire bolting cloth. They are used for silk printing, fine grading in flour mills and shale shaker screening. Polyester material bolting cloth has several benefits compared with stainless steel (mainly SUS316 ) bolting cloth, for example: high tension, less weight and less cost, etc.  In this page, we mainly introduce polyester bolting cloth, the weaving machine, its uses, benefits and sizes.

Powders and granular materials are sometimes described as having a certain mesh size. Polyester wire bolting cloth can be supplied with micron mesh sizes and thin fabrics, suitable for Textile Printing, Ceramic Printing, Glass Printing, Graphics Printing, Electronic Printing, CD/DVD Printing. With such applications, the polyester bolting cloth is also called printing screen. It is also known as filter cloth or filter screen when it is used in industrial filtration.
