Influence of plying on singles hemp yarn properties

Abstract

The return to garments that provide the maximum of natural properties became a new trend contributing significantly to environmental protection. In this situation hemp as a historical and controversial fiber gained the new importance, presumably thanks to a number of its distinct advantages. However, if hemp is ever to regain its lost ground, it must be through the development of new products and new end uses. If contemporary trends in hemp transformation into comfort textile products of added value are considered special attention must be paid to overcoming of some disadvantages such as high flexural rigidity of hemp yarns by changing their structure. In this work an attempt was made to assess the influence of hemp yarn plying on changing of its properties important for production of comfort clothing.

Trend zaštite životne sredine nametnuo je u odevanju povratak prirodnim vlaknima, i među njima posebno konoplji, kao vlaknu koje je u istoriji odevanja odigralo veoma važnu ulogu zahvaljujući svojim izuzetnim svojstvima. Ipak, da bi konoplja povratila izgubljenu poziciju, ona se mora transformisati u smislu novih proizvoda i novih oblasti upotrebe, među kojima poseban značaj imaju tekstilni materijali visokog stepena konfora. Pri tome se mora obratiti posebna pažnja na eliminisanje nekih nedostataka ovog vlakna, kao što je povećana otpornost na savijanje. U ovom radu je izvršeno poređenje jednožičnih i končanih pređa od konoplje u cilju utvrđivanja uticaja operacije končanja na neka od svojstava pređa značajnih za konfor odeće.
