  2. Total Textile Process at a Glance

  3. What is Nonwoven Fabric ? Nonwoven fabrics are broadly defined as sheet or web structures bonded together filaments (and by perforating thermally, or chemically. They are not made by weaving or knitting and do not require converting the fibers to yarn. Nonwoven Fabric is a fabric-like material made from long fibers, bonded together by chemical, mechanical, heat or solvent treatment. The binding process usually occurs through the pressing of fibres together with an adhesive, chemical binder, heat, ultrasonic pattern bonding. The popularity of Nonwoven fabrics is increasing day by day because of low cost & they are hygienic & they are easily disposal . But thecan’t easily be washed or reused properly. by entangling films) fiber or mechanically,

  4. Uses of Nonwoven Fabric Household Geotextiles Industrial/Military Health Care Aprons Soil stabilization Coated fabrics Shoe covers Tea and coffee bags Drainage Clean room apparel Lens tissue Tablecloths Road and railroad beds Air conditioning filters Surgical: caps, gowns, masks, Ironing board pads Sedimentation and erosion Military clothing Diapers Fabric softener sheets Pond liners Conveyor belts Bandages, tapes
