Abstract

A process for producing non-woven fabric which comprises collecting fibers carried by a high-speed fluid as web, and introducing it into a cloth wrapper to superpose. In this process, the web preferably has such a cross-section distribution that the weight per unit area in both edges is gradually reduced toward the edge. This process enables filament web or filament non-woven fabric with a broad width and remarkably reduced unevenness to be produced by non-woven fabric producing equipment wherein one- or two-spindle spinning machines are directly connected to each other. Therefore, a broad non-woven fabric can be economically produced in a small amount by the spinning-connected process. In addition, the width or weight per unit area of the product can be changed without changing spinning conditions, so that this process is also suited for producing a variety of products with less loss in changing the kind of product.
