V diplomski nalogi je poudarek usmerjen v obravnavo in preskušanje izdelkov iz volne za podjetje Soven d.o.o., ki se ukvarja s predelavo volne in izdelavo izdelkov iz nje. Volna je naravno organsko beljakovinsko vlakno, ki spada v skupino keratinskih vlaken in je že od nekdaj cenjeno vlakno. Odlikuje jo množica dobrih lastnosti, saj so izdelki iz volne udobni, se ne mečkajo, zaradi dobrih izolacijskih lastnosti pozimi grejejo, poleti pa hladijo. Kvalitetni volneni izdelki in mešanice z drugimi vlakni so označeni z mednarodnimi znaki kvalitete Woolmark ( 100 % volna ) in Woolmark Blend ( lahko je prisotno še katero izmed drugih vrst vlaken, kjer pa mora biti delež volne najmanj 50 % ). Vse tekstilne materiale, tudi volnene, je pred komercialno rabo potrebno kvalitativno ovrednotiti skladno z ustreznimi standardi. Šele na podlagi testiranj določenih parametrov, kot so npr. pretržna sila in pretržni raztezek, skrčenje, reakcija vodnega ekstrakta, odpornost na umazanijo, itd. je možno sklepati na lastnosti nekega tekstilnega materiala, kar je tudi vodilo za številna podjetja, ki si prizadevajo za vse boljšo kvaliteto lastnih izdelkov. Diplomsko delo zajema analizo kakovosti izdelkov iz naravne volne na osnovi testiranj različnih parametrov. Glede na specifične potrebe podjetja Soven d.o.o., so bili prav na podlagi analiz kakovosti definirani različni tehnični parametri in izdelane pripadajoče tehnične specifikacije z namenom zagotavljanja optimalne in konstantne kakovosti izdelkov prej omenjenega podjetja. The research presented within this diploma thesis deals with testing products made of wool. Wool is natural organic protein fiber which is one of the keratin fiber and has always been appreciated since the ancient times. Characterized by numerous good qualities as the products made of wool are very comfortable, they do not crush, because of the good insulation properties they are very warm, in the summer they cool down. If we stir natural wool with chemical fibres like polyester and poliamid we improve care properties, reduce the tendency of felting and increase the durability of the product. Quality wool products and mixed with other fibres are marked with international signs quality Woolmark ( 100% wool ) and Woolmark Blend ( it can be present only one type of fibre where the wool is at least 50 % ). All textile products also products made of wool, intended for commercial use, must be tested, take the appropriate measurements and in accordance with the standards product objectively evaluate. Only on the basis of appropriate measurements of the certain parameters example: breaking force and breaking elongation, shrinking, reaction of aqueous extract, resistance to dirt atc., it is possible to conclude on properties of an textile material, which is also a lead for numerous companies which effort for the best quality of their own products. The research covers analysis quality of the products from natural wool on the basis tests different parameters. According to specific needs of Soven d.o.o. company, were made on an quality analysis, defined different technical parameters and were made related technical specifications with a purpose to provide optimal and constant quality of the products before mentioned company. |
