Analysis Of The Jet Spinning And Cotton Mill Equipment Modification

At present, there are more than 60 million spinning spindles in China, Among them, 70% be made before 1990, and 30% be made after 1990, most mechanical equipments are more older, at the present equipments, more over 50% of them is extending their using age. In them, 30% of cotton spinning ability, 15% of fur spinning ability, and 30% of dyeing ability should belongs to be superseded equipments. Lots of cotton textile mills have a history more than 100 years. But what they are using equipments almost 1/3-1/2 are older. And just these older equipments are supporting china textile economic. So it is very important and necessary for us to renew our textile equipments. But it is surely also with some difficult. After Comparing with many schemes for renewing equipments, I think that air spinning is very competitive, same time, the new-type and environment protection material is being used and accepted by lots of normal people. Regarding the high quality yarn products, the awareness of people is being raised more and more, all these have taken good chance for Air spinning.The essay mainly introduce the developing conditions for present air spinning technology, yarn construction, product characteristics and air spinning be used conditions within domestic and abroad. Though developing more than 20 years, as a kind of new type spinning technology, air spinning has been made a bigger improvement. Air Spinning technology have been relatively maturity, air spinning is with a higher productive output, shorter produce progress, higher automation level and higher yarn cone, etc, all of these advantages have been extensive confirmed. Believing air spinning will be gradually developed in China, and it will occupy invariably proportion.
