People are increasingly choosing non-standard textile products that are of different features. Among these, there is a relatively rarely used knits made with dog hair. Accordingly, plain jersey fabric knits made from condensed yarns for the thesis research has been made. Yarns have contained Lithuanian’s most popular German blackface sheep wool and dogs ( Yorkshire , Spaniel, Poodle , Shih Tzu ) hair. Also, for comparison, knits made with poodle hair and PA multifilament yarns has been produced. The literature review has outlined that typical wowen fabric and knits functional properties such as thermal conductivity, air and water permeability are analyzed quite often. However, aberrant protein fibre knits are designed and analyzed more rarely. For this reason, functional properties research that regards to knits made with dog hair will evaluate the following features- thermal properties, knits fiber compositions, dependencies between knits structual parameters and functional properties. The thesis work has analyzed knits made from different dog breeds hair and different mixture yarns. The experimental results, such as structual indicators, air pearmeability, thermal conductivity indicators and thermal exhange processes were determined and evaluated. Overall, analysis has been made for 19 knits with different percentage compositions. The yarn composition influence was determined on investigated knits characteristics and knits thermal characteristics of the comparative analysis were produced. It was established that there is a relationship between analyzed knits thickness and air permeability. The thermal conductivity indicators remain stable after increasing dog hair percentage in yarn mixtures. It was also found that knits made with Spaniel dog hair have lower thermal conductivity. Knits made with Yorkshire and Spaniel hair have the best properties of thermal resistance. It was concluded, that knits thermal properties improves after adding 15–35 % other kind of protein fibers in to the yarn mixtures. |
