Non-woven cloth (or Nonwoven cloth), also known as non-woven cloth, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties.
Non-woven fabrics are moisture-proof, breathable, flexible, light-weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, inexpensive, and reusable. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by a continuous one-step method of high temperature melting, spinning, spreading, and hot pressing.
Non-woven products are rich in color, stylish and environmentally friendly, have a wide range of uses, and are lightweight, environmentally friendly and recyclable. They are internationally recognized as environmentally friendly products that protect the earth's ecology.
Non-woven fabrics are suitable for a wide range of applications, such as agricultural films, shoemaking, leathermaking, mattresses, quilts, decoration, chemicals, printing, automotive, building materials, furniture and other industries.
In addition to the above, medical disposable surgical gowns, masks, caps, sheets, and flat masks and N95 masks that we usually use for protection require non-woven fabrics for processing.
So how is the nonwoven fabric needed for making masks made?
The non-woven fabrics commonly used for making masks are spun-bonded non-woven fabrics and melt-blown non-woven fabrics. Let us first understand the spun-bonded non-woven fabrics.
The production process is: single S production line: polypropylene chip spunbond MFI (230 / 2.16) = 30 ～ 40g / 10min, and additives → suction, metering, mixing device → screw extruder → melt filter → meter Pumping, conveying → spinning die, spinneret melt spinning machine → cooling, drafting device → diffusion, netting → netting machine wire conveying → hot rolling machine reinforcement → winding machine into coil → slitting machine cutting Articles and packaging.
Main components of equipment
The single S machine is mainly composed of S spunbond system, wire laying machine, hot rolling machine, winding machine, slitting and packaging machine, steel platform frame, calciner, ultrasonic cleaning machine and other auxiliary equipment, air conditioning system and other engineering supporting equipment and Composition of electrical control system.
Spunbond nonwoven production line is used for the production of polypropylene spunbond, spun-drawn, composite-laid, hot-rolled nonwoven spunbond fabrics. Using polypropylene chips as the main raw material, supplemented with color masterbatch and anti-oxidation, anti-static, flame retardant and other additives, it produces polypropylene spunbond nonwoven fabrics with different colors and different properties to suit different uses. Can be used in medical, health, agriculture, construction, geotechnical and other industries, as well as a variety of disposable or durable materials for household and household use.
