Abstract
The physical properties of water absorbent porous acrylic fibers related to wearing comfort, i.e., water absorbency, drying, warmth retention, air permeability and frictional property have been compared with those of cotton and other fibers.
An investigation has shown that, compared to regular acrylic fibers, modified water absorbent acrylic fibers: (1) Easily diffuse water and dry. (2) Have a warmth retention intermediate between those of cotton and acrylic fibers. (3) Have difficulty in losing their air permeability even when wet. (4) Don't easily adhere to the skin even when wet.
The unique characteristics of water absorbent acrylic fibers listed above are a remarkable departure from conventional acrylic fibers as well as from other synthetic fibers.
This means an unlimited number of end uses for water absorbent acrylic fibers where moisture absorbing properties are important for comfort or fiber performance.
