形状記憶シャツ、化学はロマン(8) Permanent-press shirt, a dreamful chemistry (8)

Different from the man-made fibers, many creases of the cotton shirts after being washed is a big problem and need ironing every time. The wash-and-wear shirts have been developed to solve this problem. Chemically they have solved the problem to make chemical bridges using the resin among the cellulose polymers bearing a hydroxyl group. Historically this technology has been developed since about 40 years ago and I was also involved in this when I was working as a researcher for a certain company.
