Abstract

The invention relates to a productive method for non-woven fabrics, mainly for solving the problems including: unaverage fiber cotton falling in air permeable bellows of cotton feeding box in the producing device and complex structure of the productive device; there are mainly mechanical failure and narrow width of door of non-woven fabrics, and the quality is not average. The invention places an adjustable exhaust fan on the airpermeable lateral surface in the air permeable bellows in the cotton feeding box of non-woven fabrics producing device, and places a nozzle in the fiber average distributer, solving the problem, can be applied in the industrial production of non-woven fabrics.

Description

technical field [0001] The invention relates to a production method of nonwoven fabric. Background technique [0002] In today's textile industry, fibers such as polypropylene, vinylon, polyester, acrylic fiber, nylon, viscose fiber, cotton fiber, etc. are opened by the opener, and are directly transported to the cotton feeding box in the form of airflow, forming a horizontal and vertical distribution. The fiber layers kept within the allowable deviation range are automatically and continuously and stably provided to the carding machine, after carding, web laying, recycling knife trimming, hot pressing wheel hot rolling forming, coiler coiling non-woven fabrics, and finally The slitting machine cuts non-woven fabric products to realize automatic production of non-woven fabrics. Some cotton feeding boxes in the prior art are provided with beaters and oscillation plates; in addition, some cotton feeding boxes are provided with beaters and cooperate wi...
