Textile Age

Additional research on textile aging and degradation and on the development of chemical systems for the preservation of such degraded textiles is required before an adequate understanding of the system is attained. Hence, the major findings and conclusions summarized below are speculative and require further confirmation.

Environmental Impact of Ambient Ozone. Ozone can be toxic to plants, animals, and fish. The lethal dose, LD q, for albino mice is 3.8 ppmv for a 4-h exposure (156) the 96-h LC q for striped bass, channel catfish, and rainbow trout is 80, 30, and 9.3 ppb, respectively. Small, natural, and anthropogenic atmospheric ozone concentrations can increase the weathering and aging of materials such as plastics, paint, textiles, and mbber. For example, mbber is degraded by reaction of ozone with carbon—carbon double bonds of the mbber polymer, requiring the addition of aromatic amines as ozone scavengers (see Antioxidants Antiozonants). An ozone decomposing polymer (noXon) has been developed that destroys ozone in air or water (157). 

Most flexible foams produced are based on polyether polyols ca 8—10% (15—20% in Europe) of the total production is based on polyester polyols. Elexible polyether foams have excellent cushioning properties, are flexible over a wide range of temperatures, and can resist fatigue, aging, chemicals, and mold growth. Polyester-based foams are superior in resistance to dry cleaning and can be flame-bonded to textiles. 

It should be understood that the reported practices of polymer/additive analysis, being the focus of this book, equally well apply to additive analysis of rubbers, textile fibres, surface coatings, paints, resins, adhesives, paper and food, but specific product knowledge gives the edge. Both fresh and aged materials may be analysed, as well as those of both industrial and forensic origin.

Effect of Alkaline Deacidifying Agents on Naturally Aged Cellulosic Textiles... 

Linen textiles made from flax fibers have been known and used by mankind since antiquity (1 ). Flax has been used in many textile constructions including fine linen fabrics, laces, embroideries, and bridal fashions, and many historic linen textiles have become part of permanent museum collections. Older linen fabrics and laces are prized for their natural creamy color and luster and often have been recycled and reused. However, little is known about natural aging of linen. Most aging studies for cellulosics such as linen have involved accelerated heat-induced aging.
