INVESTIGATION OF NEW COTTON RING AND TRAVELLER

A new Ω type cotton ring and traveller is introduced.The idea of its design is based on thefacts that running travellers deviate from normal profile in three coordinate directions and such adeviation can be utilized when the balloon expands.The contact between ring and traveller at outerrace can be increased to prevent the balloon from expanding and the traveller from continuous in-clination.Consequently,the wear of inner corner of ring can be reduced.This proves the maincourse of deterioration of ring.With small sized balloon,the outer contact diminishes.The yarntension is thus adjusted and average tension is cut down.Experiments on 13 and 29 texcotton-polyester yarn spinning prove the above idea correct.With the wear of ring greatly reduced,running life is more than doubled,end breakage rate falls 30% and power consumption falls 2%.The economic profit,estimated by pilot test,is an increase of production 6.1% and 130,000 YuanRenminbi per ten thousand apindles each year.     

TEXTILE AND APPAREL EXPORTS OF THE THREE AREAS OF CHINA TO THE UNITED STATES

The three areas of China: Inland in China, Hong Kong Special Administrative Region, and Taiwan Province, are among the largest exporters of textiles and apparel in the world. They are the largest suppliers to the United States, which is the largest importing market in the world. In this research, export performances of the three areas to the United States are investigated. Analyses indicate that since the 1980s, textile and apparel exports of Inland in China to the US and its market share grew rapidly, while exports of Hong Kong and Taiwan grew much slower, and their market shares declined. Product prices of the three areas in the US market were generally higher than the market average. Especially for apparel, while export compositions of all three areas somewhat leaned towards the lower end of the market, actual product prices were substantially higher than those in the market.
