Today, I will introduce to you, the dust bag and polyester bag that are commonly used in normal temperature conditions. Polyester dust bag is made of polyester (ie, polyethylene terephthalate, abbreviated as PET, polymerized by PTA and MEG) and then spun into tow and cut fiber. PET is in the form of rice grains or flakes, with various varieties and different colors (usually the main component of the beverage bottles we come into contact with is polyester, which is sliced, generally through the two main processes of pre-spinning and post-spinning, to produce polyester dust removal Cloth bags, according to different needs, can be cut into different specifications of polyester dust bag in post-spinning, generally 4D-22D, and can be divided into two-dimensional and three-dimensional according to its curling conditions). 75% is used for polyester for chemical fiber. According to the requirements of the textile industry, polyester short dust bag and polyester filament are manufactured.

It melts when close to the flame, melts and burns and emits black smoke when it comes into contact with the flame, and continues to burn when leaving the flame, sometimes self-extinguishing, and has a sweet taste when burning, and the residue after cooling is hard and black round beads.

Strength: The strength of polyester fiber is nearly 1 time higher than cotton and 3 times higher than wool, so polyester fabric is strong and durable.

Heat resistance: It can be used at 70～170℃, which is the best in heat resistance and thermal stability among general-purpose fibers.

Elasticity: The elasticity of polyester is close to that of wool, and its wrinkle resistance is higher than that of other fibers. The fabric is not wrinkled and has good line retention.

Abrasion resistance: The abrasion resistance of polyester is second only to nylon and ranks second among synthetic fibers.

Water absorption: Polyester has low moisture regain and good insulation performance, but due to low water absorption, high static electricity generated by friction and poor dyeing performance.

Polyester dust bag classification: polyester needle punch dust bag, polyester anti-static dust bag, polyester waterproof and oil-proof dust bag, polyester coated dust bag

Polyester fiber has super abrasion resistance, good oxidation resistance and general acid and alkali resistance and poor hydrolysis resistance.

Polyester dust bag is suitable for steel plants, cement plants, coal plants, calendering industry, metallurgical industry, machinery plants, pharmaceutical industry, chemical plants, cement and building materials, etc.
