Description of melt down blown non woven 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 down blown non woven 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 down blown non woven 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:
