Air Laying

A method of forming a web (or batt) of staple fibres in which the fibres are dispersed into an air stream and condensed from the air stream on to a permeable cage or conveyor.

Air Permeability

Air permeability is defined as the porosity of a fabric as estimated by the ease with which air passes through it. Air permeability measures the warmth of blankets, the air resistance of parachute cloth, the wind resistance of sailcloth, etc. as measured on standard testing equipment.

Alginate (fibre)

A term used to describe fibres composed of metallic salts of alginic acid. Alginate fibres are made from sodium alginate, which is a natural polymer extracted from brown seaweeds. Over the last two decades, alginate fibers have become well established in the wound management industry where their ion‐exchange and gel‐forming abilities are particularly useful for the treatment of exuding wounds. In…

Alkali-Cellulose

The product of the interaction of purified cellulose. Note: in the manufacturing of viscose fibres, the cellulose may be cotton linters or wood-pulp. After pressing, alkali-cellulose usually contains approximately 30% of cellulose and 15% of sodium hydroxide, the remainder being water. During the steeping of the cellulose in sodium hydroxide (18-20% wjw) to form the alkali-cellulose, soluble impurities, including soluble…
