Melt-blown fabric: process and various application

What is the process of melt-blown fabric?

According to an academic paper, the melt-blown fabric process directly transforms polymer resins into a non-woven fabric in an integrated, single process. The melt-blown fabric manufacturer’s method was initially developed by the leading Naval Research Laboratories and commercialized by Exxon Chemical.

The melt-blown fabric’s final properties are determined by the polymer resin, ambient air conditions, conditions in the extruder, the method of bonding, and the finishing treatment, among other parameters of processing. China melt-blown fabric manufacturers show that the process’s output is a microfiber with diameters ranging from 0.1 microns to 15 microns.

What are the applications to consider for melt-blown products?

To understand the melt-blown fabric’s complete process, you need to know the main applications of the melt-blown products.

Non-woven fabrics are used in many applications, forming products used in personal hygiene, agricultural, automotive, carpeting, construction, roofing, upholstery, and several medical products. Specific examples of the types of melt-blown products include:

  • Filtration, like HEPA air filters or gas and liquid filter products
  • Respirators and face masks for medical and industrial use
  • Disposable medical garbs, like gloves, gowns, drapes, shoe coverings, masks, and head coverings
  • Sanitary products; feminine hygiene, and disposable diapers
  • Oil absorbents and liquid adsorbents
  • Artificial turf
  • Meat and vegetable packing trays
  • Coffee filter bag and tea bags
  • Disposable disinfectant wipes
  • Insulating disposable products

Filtration: This is one of the largest markets currently for melt-blown fabrics. Melt-blown fabric applications include liquid filtration, surgical face masks, cleanroom filters, gas filtration, cartridge filters, and many more.

Sanitary products: another the most common usage of Melt-blown fabric is sanitary products manufacturing. It is used frequently in feminine hygienic napkins, diaper sheets, and disposable adult incontinence fabric products.

Oil adsorbents: the process of picking up oil from water, like an accidental oil spill. It is also a common use for melt-blown fabrics. Moreover, these fabrics are used as mats in machine shops and other industrial plants.

Medical fabrics: The most extensive sections of the medical market is covered by china melt-blown fabric manufacturer. They provide several melt-blown non-woven fabrics such as disposable gowns, disposable masks, drapes, and sterilization wraps.

Apparel: Industrial disposable apparel, thermal insulation, and synthetic leather substrate are the primary uses for melt-blown fabrics, with usage in other markets projected to grow.

Electronics: Melt-blown products are also used in battery separators and work as insulation in capacitors.

Desirable properties

The melt-blown extrusion process is the manufacturing process used to make fabric known as non-woven fabric. It is made up of polymers; polypropylene. Traditional non-woven fabrics made of natural materials such as cotton are intertwined together. It means that the fabric is first formed into a yarn and then interweaved using a weaving or knitting process. The process results in the manufacture of a sheet of material by the yarn. The non-woven fabrics process does not involve joining yarn by knitting or weaving. Instead, they thermally, mechanically, or chemically wound together material formed by different molten polymers fabrics forming a fabric like a web. The resulting melt-blown fabric has various desirable properties that include:

  • High absorbency
  • Cushioning
  • Bacterial barrier
  • Filtering
  • Liquid repellency
  • Softness
  • Stretch
  • Resilience
  • High strength
  • Sterility
  • Wash-ability

Melt-blown fabric face mask:

When it comes to melt-blown fabric usage, nowadays, china melt blown fabric manufacturers are touching the sky. The reason is a melt-blown fabric face mask. As mentioned above that melt-blown gives excellent filtration and the ability to wash easily. From 3-ply disposable face mask to the N95 maks has a layer of melt-blown. It makes a face mask disposable, breathable, soft, and durable.

Future of melt-blown:

The future of melt-blown fabrics is firm to be a bright one. With characteristics like softness, versatility, porosity, and rigidity, various applications for melt-blown non-woven fabrics are widespread. As technology is growing, the opportunities to include melt-blown fabrics in more products continue to increase in the future.
