Special yarn - Import export

Wound filter-cartridges Type: PP, PPW (washed) Wound filter-cartridges are depth-filter-elements, produced in a special way of winding. Newest winding-machines guarantee a constant and high quality for filter-cartridges up to 60”. The PPW filter-element is wound with a special washed yarn. Washed yarn is free of wetting agents and prevents foaming.

The classic smooth velour flooring dominated the market for performance-oriented tennis surfaces until the 1990s. It was made from a special tennis yarn with filament thicknesses of 30-40 dtex (fibre cross-section). The further development of tennis rackets over the last 20 years has fundamentally changed the game of tennis. The development of rackets has made it possible for recreational players to accelerate the ball considerably. Today, the tennis surface has to slow the ball down more and allow it to bounce higher. The very fast classic velour has almost completely disappeared from the market in most countries as a result of the changed requirements for tennis surfaces. On the other hand, the structureless and unfilled surface is favoured by performance-oriented tennis players. With this clientele in mind, the latest development from Schöpp is a very coarse-fibre velour flooring with a single filament thickness of 200 dtex!
