How is Nonwoven Fabric used ?
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, wash ability, 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 padding's.
Special Featuers of Non Woven Fabrics
- Supreme abrasion resistance and good barrier performance
- Non-toxic, anti-bacteria and corrosion resistance functions
- Good balance of waterproofness and air-permeability
- Outstanding tensile and tearing strength, highly uniformed appearance
- Excellent physical stability after different treatments
- High level of color fastness, dyeing is not needed
Characteristics of the nonwoven fabric
The non woven fabric is light, the polypropylene proportion of only 0.9, only three-fifths of the cotton, thin and lightweight, and has excellent bulkiness, feel good. Second, soft. Composed by fine fibers (2-3D), punctuate hot melt adhesive molding, finished moderate softness with comfort.
Non woven fabric products comply with FDA food grade raw materials to produce thermally bonded molding products do not contain other chemical components, chemical stability, non-toxic, odor-free, and does not stimulate human skin. Polypropylene is chemically inert substance, excellent resistance to chemical attack strength products not subject to erosion and impact strength.
Non woven fabrics spun bond and melt blown composite products, has high strength, good filtering performance, adhesive-free, non-toxic, etc., has played an important role in the field of filtration materials for medical and industrial new application. Spun bond non woven fabrics from high-strength continuous filament, account for a large proportion of disposable protective clothing market, the latest development is adding special additives or spun bond production process finishing, so product with a flame retardant, anti-static, anti-radiation, hydrophobic guide wet, antibacterial, warmth and other features is developed. The net thermal bonding made from polypropylene spinning directly paved the intensity of the product than the average staple products better, non-directional strength aspect similar to the intensity.
Nonwoven manufacturing process
Nonwoven manufacturing can be described in simple terms as a series of manufacturing steps consisting of forming a fibrous web, entangling or bonding the fibers in the web to impart mechanical integrity to the structure and finishing/converting the fabric to impart some special properties to the fabric that the customer specifies. The manufacturing steps are given below:
- Web Formation
- Web bonding
- Finishing and converting
