one time two times or more times of carding cotton depending on specific products 4 crossly spreading the web for the fiber which has been preliminarily carded reciprocated and intervened overlapped spreading the web depending on the direction of fiber according to the requirements of grammage specifications of products the main purpose is to strengthen the tension between fibers including cotton or synthetic fibers and ensure the tensile strength of the ultimate finished products 5 feeding the fiber web fiber web includes cotton web and the web which is composed of cotton and synthetic fiber 6 pre wetting the fiber web to make sure a good moist condition before water jetting 7 water jetting employ the high pressure water needle of water jet machine to produce jet of water at high pressure to make obverse and inverse water jetting to the fiber web which enables the fibers in the fiber web to fully tangle further reinforce the tension between fibers and improve the tensile strength of the ultimate finished products at the same time the small impurities including cotton knots are eliminated purity is further improved and the good ratio of products is improved this procedure carries on one time two times or more times of water jetting according to the different purposes of products when water jetting for two times rubbing may produce flosses in the course of using the more times of water jetting the better.
