The Textile Paper Tube
The process of extruding man made fibre yarn is an extremely sophisticated technology which includes the heating of resin of plastic blends, “drawing” them through minute apertures and then threading the yarn through various “orientation” processes to create specific physical characteristics (this is known as a SPUN or PART ORIENTATED yarn). The yarn is then wound in perfect uniformity onto a cylindrical tube which allows the yarn to “lay” smoothly and to “track” perfectly, ensuring ease of unwind at the next manufacturing process. The normal speeds of “spinning” are between 3500 – 8000 mpm. The paper tube is the textile industry’s selected product to ensure these functions in the wind, rewind and unwind process.
On some occasions the wound, extruded yarn needs further “texturising” which involves a series of physical processes or blending with other yarns. His process is usually slower operating, at speeds between 500 – 2500 mpm and demands different properties than the spinning tube.
In a similar way, the paper tube or cone is the product used for natural fibres, cotton & wool. The speeds are slower, but the characteristics of the tube or cone product de-mand extremely high precision as with the paper tube for man made films.
