The paper industry or the pulp industry?
The terms “paper industry” or “pulp industry” refer to companies that manufacture paper pulp. Paper pulp is obtained from wood or recycled cardboard and paper. The paper pulp industry thus produces more than 6100 kilos of paper pulp worldwide every second ! World pulp production thus totals 193 million tonnes per year.

The paper pulp factory
Thanks to these industries, we can still color blank pages. However, what work to get to the sheet of paper starting from wood or recycled paper/cardboard! It’s a long manufacturing process.
The process of making paper pulp begins with the selection of wood or a good sorting of paper and cardboard. He continues by mixing the papers or wood fiber with water. This mixture is crushed in a machine called the “pulper”. A liquid and coarse pulp is then obtained.
This paper pulp will then begin a filtration process by going through ever finer baskets, sieves and cylinders. Today, a filtering basket, cylinder or sieve can have more than 500 parts, which is to say the complexity of the technology used to filter paper pulp. There are thus centripetal or centrifugal filters, others with continuous or vertical support, but also filters with vertical or horizontal slots.
It is at this stage that we find the profiles of TDV Profile.
TDV Profile is one of the few companies in the world to produce asymmetric shaped yarns with exceptional geometry detail and exacting tolerances (+0.015mm on the width). These profiles are ideal in the paper industry for the filtration of paper pulp.
