First developed is a low pressure plasma production type equipment. The developed ones are intermittent, such as the Swiss Teé„„choplasmaS.A., the KPR series plasma processing equipment developed by the Russian Niekmi Academy and the Italian Inter company. The KPR-180 low-pressure plasma equipment has a working width of 180cm. The running speed of the fabric is 8-80m/min, the power is 75-110kw, and the output is 12000m/batch. Its latest product, the KPR-270, has a working width of 2.7m. A factory for the production of wool shawls near Moscow used this equipment to process tops instead of chlorination to produce printable wool. It has been in normal production for many years and the quality of the products is stable and the effect is good. At present, the equipment has been produced and operated by Viero of Italy. According to the introduction, the working width of this series of products is 50-340cm, and the speed is 5-50m/min. The Institute of Chemistry of the Chinese Academy of Sciences has purchased one KPR-180 equipment and is developing its application in textile processing.
The European company Europlasma also produces industrial low-pressure plasma processing equipment with a working width of 40-180 cm. An electronic component company in Shanghai purchased several Eué„„roplasma400 devices for the cleaning of electronic components. The National Dyeing and Finishing Engineering Technology Research Center of Donghua University also purchased one of the above-mentioned equipments to carry out plasma treatment of wool, synthetic fiber and other fabrics to improve its processing and taking performance, and has achieved gratifying results.
In addition, Shandong Ironworker developed a low-pressure plasma continuous processing equipment from 1993 to 1997. The step-by-step method was used to gradually reach the required working pressure. The working width was 1.8m and the maximum operating speed was 70m/ Min. At present, Japan Bell Textile Co., Ltd. is conducting experimental production of cotton fabric desizing and scouring.
During the 10th Five-Year Plan period, the Suzhou Silk Research Institute and the China National Silk Corporation jointly developed a production-type plasma processing equipment with a working width of 1.6cm, which is still in trial operation. The advent of this equipment has taken a symbolic first step in the industrialization of this technology in China.
