Our industrial and wholesale partners are much aware of paper details and they keep on controlling the quality of goods and service. The regular tissue consumer however, in this article, may find something interesting and useful for himself though. So, here are the facts:
- The paper is shaped out of tiny, almost invisible wood fibre at length from 0.2 to 4.5mm. These fibres are got from different lumber kinds, hence they are of a diferent length. The fibres look like long rough pieces of thread. Long fibres are got from softwood lumber and serve as a forming platform of the paper, while the short fibres are got from the hardwood lumber, which serve as a filler to make the paper untransparent and its surface smooth. In other words, long fibres make paper strong and short ones make it smooth, which secures comfort in skin contact and also good printing values.
- Before output on the end, every paper is actually a water stock with 1-1,5% woodfibre compund. At a glance it looks like a muddy water with a deposit. The paper making machine is constructed of different sections and modules, which group in to two main blocks – 1. Paper stock preparation block, where the paper is deluted in a water, and – 2. The paper forming block, where the stock is put on the forming machine wire, squeezed out and dried to obtain its normal appearance.
- Every kind of paper and paperboard, whether it’s thick, multiplied, made of virgin fibre or waste paper – it is always ripped better at one side and worse – on the perpendicular side. It is explained by the fact that every type of paper is made by the couveyor type machine and outputted in reels. Accordingly, there is a so called machine direction of the paper, where the long fibres by force of forward movement straighten alongside the machine wire. Hence the paper is ripped easier at the machine direction.
- For economical reasons, paper and baord are manufactured in reels. These reels are made by a special paper making machine, which forms a paper, squeeses the water out of it with special shafts and dries the paper on the end by the Yankee cylinder. The thicker the paper is, the slower is the machine wire speed to form and dry the paper. The average speed of the tissue paper making machine is 400-600 m/sec. At such speed there is a high risk of paper being ripped. Once it happens, operators have 1 to 2 minutes to recover the production and make paper wind over the shaft again. The machine can’t be stopped in such case. Changing the winding shaft also requires rapid actions by cutting the paper and winding it on a new shaft.
- The toilet paper, like paper towel or napkins are very rarely or even never made at one production cycle from the pulp. Always, first the mother paper reel is made by a paper making machine and then, the mother roll in coverted into finished goods with required characteristics.
- A paper towel, being very similar with the regular toilet paper, is really made of different paper, which differs by its absorption and better water resistance. That is why it is said in public rest rooms not to throw paper hand towel in to the bowl.
