Wrinkle-resistant or permanent press or durable press is a finishing method for textiles that avoids creases and wrinkles and provides a better appearance for the articles. Most cellulosic fabrics and blends of cellulosic-rich fabrics tend to crease or wrinkle. A durable press finish makes them dimensionally stable and crease-free.
If the label of a piece of clothing says "acrylic", then it is made out of some copolymer of polyacrylonitrile. It was made into the spun fiber at DuPont in 1942 and marketed under the name of Orlon. Acrylonitrile is commonly employed as a comonomer with styrene, e.g. acrylonitrile, styrene and acrylate plastics.
Acrylonitrile is an organic compound with the formula CH 2 CHCN and the structure H 2 C=CH−C≡N. It is a colorless, volatile liquid although commercial samples can be yellow due to impurities . It has a pungent odor of garlic or onions. [ 4 ]
A Permanent Press is the setting that will remove wrinkles by washing clothes in warm water with a slow spin to dry. Warm water relaxes the creases while a slow spin helps keep new ones away.
Acrylonitrile butadiene styrene (ABS) (chemical formula (C 8 H 8) x · (C 4 H 6) y · (C 3 H 3 N) z) is a common thermoplastic polymer. Its glass transition temperature is approximately 105 °C (221 °F). [4]
Acrylamide (or acrylic amide) is an organic compound with the chemical formula CH 2 =CHC(O)NH 2.It is a white odorless solid, soluble in water and several organic solvents. From the chemistry perspective, acrylamide is a vinyl-substituted primary amide (CONH 2).
Polytrimethylene terephthalate (PTT), is a polyester synthesized and patented in 1941. [1] [2] It is produced by a method called condensation polymerization or transesterification.
Polyphenylene sulfide is an engineering plastic, commonly used today as a high-performance thermoplastic. [3] PPS can be molded, extruded, or machined to tight tolerances. In its pure solid form, it may be opaque white to light tan in color. Maximum service temperature is 218 °C (424 °F).
