Bakarna vlakna

Celuloza je sirovina kemijske industrije koja se upotrebljava za proizvodnju raznih proizvoda u proizvodnji umjetnih vlakana. Najvažnija upotreba je u proizvodnji viskoznih, modalnih, liocelnih, bakarnih i acetatnih vlakana. Bakarna vlakna se dobivaju iskorištavanjem kratkih pamučnih vlakana koje su otpad u prozvodnji pamuka. Zbog toga što se proizvode iz otpadnog materijala važna su u učinkovitosti korištenja ograničenih svjetskih resursa. U ovom radu prikazana su svojstva bakarnih vlakana i njihova upotreba

An investigation on the thermal comfort properties of textiles fabrics made of cellulose-based fibers

WOS: 000390416000005Yarns made of natural and man-made cellulose fibers are nowadays commonly applied in textiles. It is already apparent that the type of raw material and fabric structure influences the properties of the comfort. While designing a fabric, functional properties and basic structural parameters of fabrics must be fully understood. Clothing comfort is closely related to thermal comfort. The aim of this paper is to present a comparative of thermal comfort properties such as thermal resistance, thermal conductivity, thermal absorptivity, water vapour permeability, air permeability, and other properties for fabrics made of cotton, tencel, modal and cupro yarns. Samples were measured with the aid of Alambeta, Permetest, and Textest FX3000 devices respectively. The results of the tests were evaluated statistically and the importance levels of the relationship between the measured parameters were determined

The relationship between model types and related parameters

WOS: 000323992600006In the study, the effects of different model characteristics of garments on cutting and sewing times have been investigated. Following the experiment, a method for determining cutting and sewing times for sample product groups has been created. Product groups subject to the study are skirt and men's coat. In the study, 8 different models to the chosen skirt group and 7 different models to the men's coat group were applied. Total number of pieces, perimeter of pieces, cutting time, and sewing time were investigated. Pearson correlation was used in the study. Regression analysis was conducted to investigate the effects of other happenings on the observed process. Following the investigations of all factors and their degrees of effect, it was observed that a characteristic of a model is one of the important factors that affect the productivity and time in apparel company. The paper provides that different model characteristics of garments is very important for cutting and sewing times
