The Textile Industry
Textiles are either woven or nonwoven. Both kinds of textiles have wide applications in which the porous structures of textiles determine their performance. For example, dressings for wounds in health care applications allow air to flow while not permitting bacteria to pass. Pillow covers and bed sheets are designed so that mites cannot pass through. Filters used in the food and beverage industry prevent passage of dust particles, bacteria, viruses, spores and pollens. Felts are used in the paper industry to drain water from the mat of pulp. Breathable textiles are permeable to air and moisture, but not to water. Measurement of pore characteristics of textiles is essential for design and selection of textiles and evaluation of their performance.
