The invention

The problem to be solved:
Special processing of hemp fibre for the production of high value threads and textiles with a special character.

Definition:
Appropriate production and fibre finishing procession of Hungarian hemp varieties making them – by special chemical and mechanical processing - suitable not only for the fibre spinning industry, but also for cotton and wool spinning and lies technologies. By these means one can obtain finer threads like the conventional with other characteristics and fashionable, modern hemp-like textiles for clothes and household.

Presentation:
Hemp fibres of length and fines obtained by traditional processing are not suitable for fine threads and light textiles. The essence of the method in conformity with the invention is that by chemical and mechanical processing during the preparation hemp fibre shall be cut, splitted and cleaned as for the expectations of cotton or wool industry. The thread prepared for these purposes shall be mixed with minimum 15% other natural or artificial threads obtaining so threads of a linear density of 33 – 100 tex, essentially finer than the actually processed. The hemp character of the processed thread depends on the fibrous material rate. By an adequate choose of fibrous material the dominance of hemp is to realise using even 15% hemp. By using hemp-like threads produced by modified cotton or wool technologies one can produce lighter textiles of higher quality with suitable touch for specific uses such as light summer clothes for ladies, gentlemen and children, working dresses and jeans-like products. For the household textiles one can exploit the possibilities given by colour effects of threads with different hemp content. So textiles with popular character like curtains, table-clothes, bedclothes can be produced. From hemp-like threads one can produce textiles also for particular purposes like for shoe uppers, handbags, bags or caps. Textiles having special characteristics increase the national product assortment by their exclusivity and are more competitive.

Advantages:
The shortened and refined hemp threads are suitable for mixing with cotton, wool, viscose and other natural or artificial threads. These mixtures make possible the production of finer hemp-like threads having more favourable physical properties, with a higher productivity as by the traditional thread sptinning technologies. Using fine hemp-like fibres one can produce high value over clothing of special character and household textiles.

Stage of development:
Appropriate hemp production, special fibre preparation, modified textile industrial production technology.
