Stable shaping process technology opens the
doors to fashion, a transitory fantasy determining the form, color, design
and new effects of textiles and clothing. This process, presently, is typical
in fashionable cotton industry products and is also one of the mature
technologies developed in textile and fibre industry. The features such as
fitness, comfort, easiness to stretch, etc, are highly desired today.
New purified cotton is a quality product
material made using this high technology, that overcomes the traditional flaws
of shrinkage, wrinkled clothes, and improves dramatically the natural
properties of softness, comfort of cotton.
Liquid ammonia finishing or Liquid
ammonia mercerising’ refers to the
process that truly revives the cotton through the expansion of liquid ammonia
at an ultra-low temperature inside the fibre. When the cotton fibre is treated
at -33ø C liquid ammonia, ammonia at ultra low temperature will permeate
immediately into the crystallographic structure of the fibre. Stress will be
released through interior expansion, which makes the fibre cavity round and
smooth and rearranges the molecular structure, thus the crystallographic
structure becomes slack and stable. This physical change makes the surface of the
entire fabric smooth and bright, with solid and soft feel, so elasticity and
wash-and-wear is fully achieved.
The benefits of liquid ammonia mercerising lies
in the following effects that can be achieved simultaneously:
The superb appearance, feel and brilliancy of dyed shades, make the buyer select the ammonia mercerised garment/fabric rather than the regular caustic mercerised one.
- Low shrinkage post washing
- Increase in wrinkle resistance
- Increase in fibre elasticity
- Softer to touch and brighter
- Enhanced tensile strength
- Dimensional stability
Resistance to abrasion
Dyeing uniformity, dyestuff affinity, colour solidity
Wash and wear properties

Mercerising and resin finishing:
Compared to mercerising or resin finishing,
though mercerising has the ability of anti-shrinkage, it cannot attain
anti-crease and softness; while resin finishing enhances anti-crease with the
strength decreasing.
