The invention relates to a method of making clay Highly voluminous fiber structures, in particular τοη yarns, dureh thermal b * w. ohemiecbe treatment τοη synthetic fibers or their mixtures with other chemical or natural fibers.

It is intended to take care of what is particularly important in hindsight dl · Possibility of saving on textile raw material.

A particularly important property is the thermal insulation · textiles hold warmth only partly through the actual hatred of the pisers. In the predominant part of the cash register, the «poor eolation forms the air, which is a 2 times better insulator than cotton and a 6faea is better than great.

Voluminous textiles not only have favorable heat-insulating properties a better and more roll grip, better permeability and coverage, a higher grommet and a better ·· appearance.

At present, two basic principles of making clay bulky ⁷ asorn and yarn are known. The first “principle of enlarging the volume is based on aeohani? Ch” r shaping ”. This process is used especially for“ forms of synthetic silks
