Development of animal husbandry in Tibet over the last 40-odd years have spurred attendant growth in textile production and other light industry. Consuming more than 1,250 tons of raw wool every year, the 2,290-spindle Nyingchi Woolen Mill is the region's textile leader. It produces more than 100 varieties of woolen fabrics, knitting wools and carpets. In addition to that going to satisfy local demand, some production is sold elsewhere in China and a portion exported. Leather production is an industry particularly characteristic of Tibet, with tanyards found in Nagqu, Xigaze, Qamdo, Ngari and Lhasa, producing more than 50 types of products, including heavy leather, light leather, fur coats, leather clothing, leather shoes and horse gear. In 1988, the Lhasa Tanyard, with assistance from the Federal Republic of Germany, invested 13 million marks to import equipment, and conduct technological transformation. It can process 60,000 hides annually, producing 40,000 pairs of leather shoes and 10,000 other leather articles. The quality of the beer produced by the Lhasa Brewery has improved steadily since the introduction of reforms designed to install a modern enterprise system. The product was awarded the title of Established Star Quality Chinese Beer for 1994.
