The first one is the most popular method to evaluate the quality of interlacing yarn and we can prove it meets the theory of purification. The second one is modified according to the coefficient ...
Get PriceWe have developed an equipment by which a yarn can be intermittently exposed to air jets in the yarn axial direction. Without a conventional interlacer, an attempt is carried out by using this equipment to produce interlaced yarns having the various number of tangles under the conditions that the air pressure, the yarn speed, the feed ratio and the nozzle height are constant.
