What is Nonwoven Fabric?
Nonwoven fabrics are broadly defined as sheet or web structures bonded together by entangling fiber or filaments (and by perforating films) mechanically, thermally, or chemically. They are flat, porous sheets that are made directly from separate fibers or from molten plastic or plastic film. They are not made by weaving or knitting and do not require converting the fibers to yarn.
How is Nonwoven Fabric used?
Beyond simple definitions, these engineered fabrics open up a world of innovative possibilities for all types of industries.
Nonwovens may be a limited-life, single-use fabric or a very durable fabric. Nonwoven fabrics provide specific functions such as absorbency, liquid repellency, resilience, stretch, softness, strength, flame retardancy, washability, cushioning, filtering, bacterial barriers and sterility. These properties are often combined to create fabrics suited for specific jobs while achieving a good balance between product use-life and cost. They can mimic the appearance, texture and strength of a woven fabric, and can be as bulky as the thickest paddings.
Following are just a few of the properties that can be attained using nonwoven fabrics:
Features and applications based on the feature of nonwoven fabric:
- Absorbency Agricultural seed strips, Disposable diapers, Laundry aids, Hygiene products, Female Menstruation napkin, Filters, Household & personal wipes,mops.
- Bacterial barrier Sterile medical-use products, Disposible face mask, surgical gown, tea bags,
- Cushioning Civil engineering fabrics, Civil engineering geotextiles, Upholstery for furniture and garment and bags and suitcases,
- Insulation insulations for electric contruction
- Filtering tea bags, filtering for purifier,
- Flame retardancy house wraps, wall covers, wall papers
- Liquid repellency A woven medical fabric suitable for making a CSR wrap was prepared from woven 70 denier, 34 filament 100% polyester yarn woven in a plain weave pattern with a final construction of 144 ends and 87 picks per inch and a weight of 2.46 ounces per yard. The greige fabric was washed, processed to remove all foreign substances and debris, then dried.
- Resilience Automotive headliners, Automotive upholstery, House wraps
- Softness shopping bags, bags for packing, cushioning for garment and furniture, face mask, fabric for pillows inter liners
- Sterility shoe’s cover, head cover, surgical gown.
- Strength Envelopes, spring’s pockets, shopping bags,
- Stretch disposable towels, female personal napkins
- Heat preservation Agricultural coverings, row covers, floating row covers, covers on low tunnels, covers on green house, Carpeting, Roofing
- Washability Apparel linings,table runners,
- Impressionability Tags, Labels, Wall coverings
Today, innovations in nonwoven fabrics are growing as rapidly as the demand for them, with almost unlimited possibilities for a wide variety of industries, to be honest, nonvoven fabrics are most useful fabric in the world. Even, it is most useful material in the world.
