The main component of polyester non-woven fabric is polyester. Polyester fiber belongs to chemical fiber and is a polymerization product of terephthalic acid or diethyl terephthalate and ethylene glycol. It has high strength, good elasticity, good heat resistance, smooth surface, good wear resistance, good light resistance, corrosion resistance, but poor dyeability. Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, low price, and recyclable. For example, polypropylene (pp material) pellets are often used as raw materials, which are produced in one step after high-temperature melting, spinning, laying, and hot-pressing.
Polyester non-woven fabric is mainly made of polypropylene resin, which has a light specific gravity, which is only three-fifths of that of cotton. It is loose and feels good. High flexibility, composed of thin fibers, light point hot-melt bonding molding. The finished product is moderately soft. Water-repellent and air-permeable. Polypropylene slices do not absorb water and have zero moisture content. The finished product has good water-repellency. It is composed of fibers with porosity and good air permeability. It is easy to keep the cloth surface dry and easy to wash.
The product is made of suitable materials, does not contain other chemical ingredients, has stable performance, no peculiar smell, and does not affect the skin. Polypropylene is a chemically inactive substance, not moth-eaten, and can block the corrosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and the strength of the finished product will not be affected by corrosion. The product is water-removing, not moldy, and can block the corrosion of bacteria and insects in the liquid, and is not moldy. It is made of polypropylene spinning directly laid into a net and thermally bonded. The strength of the product is better than that of ordinary staple fiber products. The strength has no directionality and the vertical and horizontal strengths are similar.
Polyester non-woven fabric is a fabric that does not require spinning and weaving. It is a sheet, web or batt made of oriented or randomly placed fibers through friction, cohesion or bonding. These combinations are combined with each other. Its flame retardant mechanism is to participate in flame retardants. Flame retardants are additives for materials, which are used in polyester plastics, textiles, etc., and are added to polyester to achieve the purpose of flame retardant by increasing the ignition point of the material or preventing the material from burning.
