Raw material (1) Nonwoven fabric
Non-woven fabric is a fabric-like material made from staple fibre ( short) and long fibres
( continuous long), bonded together by chemical, mechanical, heat or solvent treatment, which
are neither woven nor knitted.
For example, a slurry of fibers, water and other ingredients may be rolled into flat sheets and then
dried-this is mechanical treatment. An international definition of “nonwovens” can be found in
ISO Standard 90992:2011.
In contrast, woven fabric holds together by the interlacing or weaving of two or more continuous
fibres, and knit fabric consists of one continuous yarn that is looped repeatedly around itself.
According to process of production, nonwoven can be classified as below:
1. Dry-laid process
1.1 Chemical bonding
1.2 Mechanical bonding
1.2.1 Needle punching
1.2.2 Spun-lacing
1.3 Thermal bonding
2. Wet-laid process
3. Polymer-laid process
3.1 Spun-bond
3.2Melt blown
The Spun lacing process is a nonwovens manufacturing system that employs jets of water to
entangle fibers and thereby provide fabric integrity.
From all types of nonwoven, Spun-lace nonwoven, composite of different fibers, is specifically
engineered for the intended use of the wipe.
