This equipment is used for the production of melt blown nonwoven fabric.Different colors and functions of melt blown nonwovens are produced with polypropylene fiber as the main raw material, supplemented by Color Masterbatch, antioxidant, electrostatic electret, flame retardant and other additives. The products are widely used in industrial felt, industrial oil absorbent cloth, industrial sound insulation cotton, industrial high efficiency filter material, etc. at the same time, the production line can also produce disposable ordinary melt blown cloth for mask and melt blown cloth for mask which can achieve N90 or above high efficiency by adding electret masterbatch and electrostatic electret treatment.
Description of melt blown nonwoven fabric machine melt blown machine is the most core material of mask, melt spraying cloth mainly USES polypropylene as the main material, the fiber diameter can reach 1 ~ 5 micron.The microfiber with unique capillary structure increases the number and surface area of fiber per unit area, so that the melt spray cloth has good filtering, shielding, insulation and oil absorption.Can be used for air, liquid filtration materials, isolation materials, absorption materials, mask materials, warm materials, oil absorption materials and wiping cloth and other fields.
Working principle of melt blown nonwoven fabric machine Polypropylene PP material through the feeding machine into a single screw extruder to squeeze out the polymer melt, through high-speed hot air or other means, the polymer by extreme stretch and form very fine short fiber, and agglomerate on the porous formation of fiber network, and finally through its own bonding and strengthening to form non-woven fabric, finally produce melt spray cloth.
Product process of melt blown nonwoven fabric machine Fusion-sprayed fabric is a polymer melt extruded from the nozzle hole of die head by using high-speed hot air flow to draft the thin flow, so as to form a microfiber and collect it on the condensation screen or roller, at the same time, its own adhesion and become a fusion-sprayed nonwoven fabric. The production process of melt spraying cloth is mainly as follows:
1. Melt preparation 2. Filtration
3. The measurement
4. The melt is extruded from the spinneret
5. Melt fine draft and cooling
6. Into the net
