Standards of industrial production were not introduced until the 1990s, when the Chenille International Manufacturers Association (CIMA) was formed with the mission to improve and develop the manufacturing processes. From the 1970s each machine head made two chenille yarns straight onto bobbins, a machine could have over 100 spindles (50 heads). Giesse was one of the first major machine manufacturers. Giesse acquired Iteco company in 2010 integrating the chenille yarn electronic quality control directly on their machine. Chenille fabrics are also often used in Letterman jackets also known as "varsity jackets", for the letter patches.
