Meltblown nonwoven in Bangladesh is the key material in the facial mask that plays a filtering role. It is the “heart” of the face mask. It not only can block larger dust particles, but absorb fine dust, bacteria and virus droplets through the electrostatic charge on the surface. As a necessary raw material for filter face masks, a general medical surgical mask needs to use 1 layer of melt blown, and a N95 face mask needs at least 3 layers of meltblown nonwoven fabric. 1 ton of spunbond meltblown spunbond can make 1 million medical surgical masks. While, it not only for face mask production, but for various application fields.
Application Scope of Meltblown Nonwoven
(1) Medical and health cloths: surgical gowns, protective clothing, disinfection wraps, masks, diapers, sanitary napkins, etc.;
(2) Home decoration cloth: wall cloth, table cloth, bed sheet, bedspread, etc.;
(3) Garment cloth: lining, adhesive interlining, wadding, shaped cotton, various synthetic leather base cloth, etc.;
(4) Industrial cloth: filter material, insulating material, cement packaging bag, geotextile, covering cloth, etc.;
(5) Agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal insulation curtain, etc.;
(6) Others: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc.
AIMIX Exporting Melt Blown Fabric All Over The World
Up to now, AIMIX Group, one of reliable meltblown manufacturers in China, has exported meltblown material over 30 countries all over the world, including Bangladesh, Vietnam, Philippines, Pakistan, Malaysia, Indonesia, Singapore, Korea, Peru, Brazil, Germany, France, Laos, South Africa etc. With our own meltblown nonwoven machine, we can promise to produce quantity of meltblown fabric to ensure sufficient supplying in the market. Therefore, every customers can make orders from us because AIMIX can export goods during delivery date according to the contract. Here are some pictures of transporting.
Features of AIMIX Spunbond Meltblown Fabric
1. SMS spunbond meltblown spunbond is mainly made of polypropylene. In addition, the fiber diameter can reach 1 to 5 microns.
2. Many voids, fluffy structure, good wrinkle resistance.
3. The unique capillary structure of superfine fibers increases the number and surface area of fibers per unit area. Thus, the pp melt blown has characteristics of good filterability, shielding, heat insulation and oil absorption.
4. It can be applicable for many fields, such as air, liquid filter materials, isolation materials, absorbing materials, mask materials, thermal insulation materials, oil absorbing materials and wipe cloths.
The Differences of BEF99, BEF95 and BEF90 Meltblown
The meltblown nonwoven fabric is divided into civil medical grades of 90, 95 and 99. Different grades correspond to different face masks. If the melt blown cloth can reach level 99, the electrostatic filter of the melt blown cloth must filter out 99% of the particles and bacteria in the air to achieve the purpose of protection. Therefore, the raw material PP for the manufacture of meltblown is particularly important, and the grade of meltblown cloth made of meltblown PP can reach up to 95 grades, of which electret masterbatch can be added to achieve the electrostatic adsorption effect and the amount of electret masterbatch added is about three percent.
In general, manufacturers use the BEF99, BEF95 and BEF90 Meltblown for different degrades of masks as following:
Gram weight: 18g-500g
Width: generally 160cm and 180cm (also can be customized according to the customer’s special demands)
Meltblown Nonwoven is to use high-speed hot air flow to draw the thin stream of polymer melt extruded from the nozzle hole of the die, thereby forming ultra-fine fibers and collecting them on the net curtain or roller. In the meanwhile, bonding themselves, then becoming Melt-blown non-woven fabric.
How does meltblown machine manufacture the meltblown? The production process of melt blown cloth is mainly as follows:
Polymer feeding → melt extrusion→fiber formation→fiber cooling→web forming→bonding (fixed web)→trimming and winding→after finishing or special finishing
PP polymer raw materials are generally made into small spherical or granular slices, poured into a barrel or hopper, and then fed into the screw extruder.
At the feed end of the screw extruder, the polymer chips should be blended with stabilizers, brighteners and other additives and necessary raw materials such as masterbatch. Then entering the screw extruder after being fully mixed and heated at high temperature to be melt. Finally the melt is sent to the spinneret by the metering pump through the filter. In the meltblown process, the general extruder also uses its shearing and thermal degradation effects to reduce the molecular weight of the polymer.
The filtered clean melt passes through the distribution system and then evenly feeds each group of spinnerets to ensure the extrusion volume of each spinneret uniform. The spinneret of meltblown fiber is different from other spinning methods, the spinneret holes must be arranged in a straight line, and the upper and lower sides have high-speed air jet holes.
A large amount of room temperature air is sucked in at the same time on both sides of the spinneret, mixed with the hot air stream containing ultrafine fibers to cool it down, and the molten ultrafine fibers are cooled and solidified.
In the production of meltblown fiber nonwovens, the spinneret can be placed horizontally or vertically. If placed horizontally, the superfine fibers are sprayed on a circular collecting drum to form a web; if placed vertically, the fibers fall onto a horizontally moving web forming curtain to condense into a web.
Adhesion (fixed net)
The self-adhesive reinforcement mentioned above is sufficient for some applications of melt blown cloth, such as: the fiber net is required to have a relatively fluffy structure, good air retention rate or porosity Wait. For many other applications, self-adhesive reinforcement alone is not enough. Hot-roll bonding, ultrasonic bonding or other reinforcement methods are also required.
