Opisana je opcenito fiziologija rada, odnosno proucavanje covjeka kao fizicko, tjelesno i fiziolosko bice. Analiziran je rad radnika u tekstilno-mehanickoj tehnologiji te njegov utjecaj kao posljedica psihofizickog napora. Pojava umora tijekom rada i njegov nastanak izravno utjece na ucinak radnika. Normirano radno mjesto, rad u smjenama, međuljudski odnosi, uvjeti rada te skromni prihodi najcesci su uzroci veceg psihofizickog napora radnika u tekstilnoj industriji. Stoga se u ovom radu analizirao ne samo rad i ucinak rada, vec i covjek kao fiziolosko bice.

National Custumes of the Dalmatian Hinterland and Littoral Zone

Darko Ujević Stana Kovačević Ksenija Doležal Renata Hrženjak Blaženka Brlobašić Šajatović

Pod narodnom nosnjom podrazumijeva se odjeca koja se nosila do druge polovice 19. stoljeca, a danas predstavlja etno bastinu svakog naroda. U ovom radu dat ce se pregled hrvatskih narodnih nosnji s naglaskom na dalmatinsko zaleđe, odnosno Zagoru i Ravne kotare. Analizirat ce se njihove slicnosti i razlicitosti. Prema analizama provedenim u ovom radu može se utvrditi da usprkos relativno velikoj povrsini dalmatinskog zaleđa (Dalmatinska zagora i Ravni kotari) gotovo da ne postoje razlike u narodnoj nosnji, obicajima, dijalektu i dr. Iako je južni uzdužni pojas dalmatinskog zaleđa neposredno uz priobalje i otoke, slicnosti među narodnim nosnjama i obicajima gotovo da i nema. Može se pretpostaviti da je tu razlicitost uvjetovao nacin života i vremenski uvjeti koji se razlikuju stoljecima između dalmatinskog zaleđa i priobalja. Osim toga, okupacija pojedinih krajeva Hrvatske od drugih naroda također je utjecala na obicaje i stil života. Uspoređujuci sjeverni pojas dalmatinskog zaleđa, Like i Hercegovine, koji su također u neposrednoj blizini, razlicitost narodnih nosnji i obicaja su male.

Impact of Fabric Construction on Adsorption and Spreading of Liquid Contaminations

Materials (2022)

Snježana Brnada Tanja Pušić Tihana Dekanić Stana Kovačević

A contamination on a textile material is defined as an undesirable, local formation that deviates in appearance from the rest of the material. In this paper the relationship between the shape and surface of liquid contaminations and the firmness factor of woven fabric is investigated. The interdependence of constructional and structural parameters of raw and bleached cotton fabrics were analysed. The results show that selected contaminations are distributed differently, primarily depending on the construction characteristics of the fabric, type of contamination and hydrophilicity of cotton fabric.

ANALYSIS OF ARTIFICIAL LEATHER WITH TEXTILE FABRIC ON THE BACKSIDE

Journal of textile and apparel technology and management (2009)

Darko Ujević Stana Kovačević Larry C. Wadsworth Ivana Schwarz Blaženka Brlobašić Šajatović

The fundamental characteristics of a textile fabric intended for the vehicle interior is presented. Chemical and physical-mechanical properties of artificial leather with bonded textile fabric on the back side are analyzed. The most important parameters for leather durability are: breaking force and elongation-at-break, and these properties will be tested in different circular directions. Likewise, chemical properties of artificial leather and basic construction parameters of the textile fabric are investigated. When using artificial leather, physical-mechanical properties of artificial leather as well as the quality of the seams are most important. In addition to the results obtained, physical-mechanical properties and aesthetic evaluation of the joined places will be compared.

Laminated textile composites – Problems with bonding layers and sewing

Journal of Industrial Textiles (2021)

Stana Kovačević Darko Ujević Jacqueline Domjanić Samir Pačavar

In this paper laminated composites with woven fabric on the front side, polyurethane foam (PU) in the middle and knitted fabric on the back side were analyzed. These materials are widely used in the automotive industry, medicine, protection activities and other groups of technical textiles Based on analyses and problems encountered in practice, the hypothesis was made that the speed of joining the components into a laminated composite influences the needle penetration force and finally the seam quality when sewing. Investigations were performed using three GB needle systems, two PU thicknesses (2 and 4 mm) and three joining speeds (30, 35 and 40 m/min). According to the results obtained, it can be concluded that higher joining speeds determine lower penetration forces. By systematic analysis of the sewing seam the deformation of laminated composites occur at stitch points, which is caused by hardened PU residues after the lamination of components to a composite. Heating the needle during sewing resulted in partial melting of PU and adhesion of needle to the material is penetrating through which means damage to the needle and seam. This negative occurrence is more pronounced at lower bonding speeds, for higher PU thickness and thicker needle. Based on the results obtained it can be claimed that bonding speed, polyurethane thickness (PU) as well as needle type affected the penetration forces of sewing and seam quality.

CHANGES IN PROPERTIES OF WOOL FIBRES AND YARNS THROUGH THE PHASES OF THE PROCESS OF SPINNING AND WEAVING IN DIFFERENT WEAVES

TEKSTİL VE KONFEKSİYON (2015)

Stana Kovačević Ivana Schwarz Snježana Brnada

The aim of this study was to investigate the changes in properties of wool fibres through the all phases of the production processes from fibre to woven fabric. Research on fibres were carried out before spinning, after spinning and after weaving and on the yarns before weaving and after weaving. According to obtained results it can be determined that noticeable changes in the properties of the fibres and yarns through these phases have arisen. The biggest changes were recorded in the process of weaving. It was also noticed that the weave influences the changes in properties of the fibres, yarns and fabrics. Direction of the fabric that had a greater number of threads transitioning from fabric face side on the reverse side, and vice versa, have major changes in fibres and yarns strength utilization in the fabric, which means that the weave directly influences the changes in the fibres and yarns properties

Natural Modified Starch and Synthetic Sizes in Function of Characteristics of Sized Yarn

Fibres and Textiles in Eastern Europe (2016)

Stana Kovačević Suzana Đorđević Dragan Đorđević

The aim of this study was to investigate the changes in properties of yarn made by sizing with synthetic and natural modified corn starch. Different procedures for obtaining modified natural (corn) starch and various combinations of natural and synthetic sizes were used to explore the differences in the properties of sized yarn. The sizing process was carried out wunderith constant conditions in a newly developed laboratory sizing machine on twisted cotton yarns of 20×2 tex and 30×2 tex. According to the results obtained, yarn sized with synthetic sizes has substantially better properties than those which are naturally sized with modified starch. However, sometimes these differences are not significant or they do not exist at all. Twisted yarn is not always necessary in sizing in order to increased its strength but rather to protect the surface from wear and refine projecting fibers; in this case natural modified starch from corn can meet the requirements. The significance of this research is the application of natural sizes, improvement of the sizing process with natural modified sizes using new achievements in the development of the sizing process, and thus creating a positive environmental and economic impact.

Replica of Folk Cloth on a Contemporary Loom

Fibres and Textiles in Eastern Europe (2014)

Stana Kovačević Josip Hađina Alena Mudrovčić

Department of Textile Design and Management Faculty of Textile Technology, University of Zagreb, Zagreb, Croatia e-mail: stana.kovacevic@ttf.hr Abstract The principle of making a woven fabric with an ethnic motif according to a costume design from Posavina, Croatia, is described. The specificities and complexities of making these fabrics on weaving looms are described. One way of replicating the patterns of old fabrics as well as the manufacturing problems and technological process are presented. The results led to the conclusion that the possibilities of fabric patterning on looms are numerous, and the replication of some motifs on looms is possible in a shorter time than on hand looms. However, industrial production is still recognisable, and it is impossible to get a characteristic tinge provided by hand weaving. In this sense, the aim of this paper is to investigate and compare the advantages and disadvantages of the industrial production of patterns with ethnic motifs for manufacturing national costumes, which could prove satisfactory when replacing original patterns.
