Biodegradation of yarn from PLA/CV in commercial soil at controlled conditions and in garden soil at local climate conditions was researched. The tensile properties of the yarn treated in the soil changed rapidly in the first ten days. After nine months, the tensile force decreased by 26% and the breaking elongation increased by 8%. Under the researched local weather conditions the yarn biodegraded partly in the soil in one vegetation period. Changes in the yarn structure after complete biodegradation of a viscose component were large enough to allow normal development of a plant’s roots.

COBISS.SI-ID: 2051184The lecture was for students of third study year on textile field at the Technical University, Faculty of textiles in Istanbul, Turkey. The lecture wad divided into presentation of mechanical properties of fabric such as extension, bending and shear, drapeability of fabric and presentation of existing measuring systems or equipment for mechanical properties as well as presentation the study cases of applications the advance engineering methods for analysis the treated fabric properties.

COBISS.SI-ID: 12636182With the purpose to determine the resistance of shirting fabrics to seam slippage, the suitability of methods EN ISO 13936-1 and EN ISO 13936-2 was evaluated on finished 100% cotton shirting fabrics with different constructional characteristics, and after 15 and 25 washing cycles. In comparison to the EN ISO 13936-2 method, the method according to EN ISO 13936-1 is time consuming and more complex. The EN ISO 13936-2 method is fast and simple and, therefore, recommended for testing fine shirting. Under test force of 60 N, the seams of shirting fabrics opened in the range of 1.2 to 1.9 mm.

COBISS.SI-ID: 2328432The quality of the Slovenian autochthonous flax from Bela Krajina was compared with the flax of Laura genotype (EU purchase catalogue). Flax seeds were sowed in rows with row spacing of 8.5/17/34 cm. The plants were plucked at the end of the yellow maturity, the retting process was carried out 4-5 days in still water of 20-30 oC and 20-40 oC, after which the plants were dried. The fibres were extracted by traditional method. When the raw spacing was wider, the Slovenian autochthonous flax developed shorter and thinner stems. Domestic autochthonous flax is comparable with the Laura flax.

COBISS.SI-ID: 2327920In this study was monitored the influence of textile care processes on the properties of functional textiles treated to achieve better comfort, softness, easy care and sewability. Testing of untreated and functional textile fabrics before and after washing and wet cleaning was done following standard procedures for determination of stifness (ASTM D 1388-64: 1989), tensile properties (EN ISO 13934-1:1999) and wrinkle recovery (EN 22313:1992). The results indicated that wet cleaning process can be applicable as prime procedure for maintenance of functional textiles.
