U radu Tekstil u praistoriji na tlu Srbije istraženi su arheološki dokazi proizvodnje tekstila u praistoriji od ranog neolita do gvozdenog doba. Obuhva eno je više od 160 naselja sa razli itim predmetima koji mogu da se povežu sa nekim oblikom izrade ili upotrebe tekstila. Ozna eni su kao potencijalni alat u proizvodnji tekstila. Nalazi su iz naselja star eva ke i vin anske kulture, preko eneolitskih kultura bakarnog doba, bronzanodobnih nalaza, do pojave gvož a na tlu Srbije. Akcenat je dat na tehnološke mogu nosti, odnosno na istraživanje predmeta specijalizovanih za proizvodnju i preradu tekstila. Utvr ene su procedure istraživanja i metodologija analize arheoloških predmeta i otisaka strukutra. Tegovi za tkanje i pršljenci su tipološki opredeljeni u klase po morfologiji i ispitana su radna ošteć enja. Izvori informacija su arheološka dokumentacija i predmeti od razli itih materijala, osnovano vezani za proizvodnju, preradu, doradu i oblikovanje tekstila. Ispitani su predmeti koštane industrije: igle, noževi za tkanje, plo ice sa perforacijama. Kerami ki oblici su: tegovi, pršljenci, kalemi, sudovi sa otiscima tekstilnih struktura na dnu ili recipijentu. Antropomorfne figurine pominjane u radu su ispitane po mogu nosti upotrebe tekstila u odevanju. Posebno su ispitani kontekstualni dokazi postojanja razboja sa tegovima u ku ama vin anske kulture. Grupe tegova prona ene u ku ama iz naselja Vin a Belo brdo, Obrež Baštine, Gomolava, Crkvine Mali Borak analizirane su po mogu nosti upotrebe na razboju. Utvr ena je nedvosmislena veza tegova i razboja, izvršena rekonstrukcija potencijalnog položaja u sklopu razboja i istraženo rasejanje tegova pri padu na pod. Otisci struktura prepleta na dnu sudova pokazali su izvesnu homogenost. Skoro svi su tip pletarske strukture, izra ene od neprera ene sirove biljke dvostrukim uvratnjem potke preko pasivne osnove, delovi manjih predmeta izra enih rukom. Visok stepen korelacije izme u kulture i sredstava za proizvodnju tekstilnih površine ogleda se u pojavi odre enih tipova alata u korpusu arheoloških predmeta, izrazitoj eksploataciji i nestajanju u novim kulturama. In the dissertation Prehistoric Textile in Serbia we have researched archeological evidence related to textile production in the prehistoric period from the early Neolithic to the Iron Age. In this study, more than 160 settlements have been encompassed where diverse artifacts had been found which could be linked to some form of textile making or its usage. These artifacts have been designated as potential tools in the production of textile. The findings belong to settlements from the Starcevo and Vin a cultures, ranging from Eneolithic cultures of the Copper Age, across various Bronze Age findings, to the appearance of the Iron Age on Serbian soil. Accent has been given to the possibility of the existence of textile producing technology, i.e., research has been conducted related to artifacts that were specialized for the production and processing of textile. We have determined the research procedures and the methodology for analysis of the archeological artifact and imprinted structures. Loom weights and spindle whorls have been classified, typologically, according to their morphology and we have examined the wear and tear of these artifacts in the production process itself. Our sources of information were derived from relevant archeological documentation as well as artifacts made of different materials, but which are credibly linked to production, processing, finishing work and shaping of textile. In our research, we have examined artifacts that belong to bone industries: needles, weaving knives, and small tile-plates with perforations. The ceramic implements are weights, spindle whorls, spools, vessels with remains of imprinted textile patterns and structures on the bottom of the vessels. The anthropomorphic figurines mentioned in the study have been examined according to the likely usage of textiles for the purpose of clothing. We have, especially, examined and researched the contextual evidence related to the existence of looms with weights in the dwellings belonging to the Vin a culture. Groups of weights that have been found in the houses and dwellings located in the settlements of Vin a Belo Brdo, Obrež Bastina, Gomolava, and Crkvine Mali Borak have been analyzed according to the likelihood of loom usage. An unequivocal connection has been determined related to the weights and looms, and we have performed reconstructions of their potential positions within and on the looms and have explored their displacement positions resulting from their falling to the floor. The accidentally imprinted patterns of woven structures on the outside bottom of the found vessels have shown certain homogeneity. Almost all of them are of the inter-twined type pattern structure made of unprocessed raw plants by means of the double inter-twining of the weft over the passive warp, parts of smaller hand-made objects. A high degree of correlation between the culture and means of production of textile surfaces is reflected in the reappearance of certain types of tools in the corpus of archeological artifacts, evidence of their considerable exploitation and their disappearance in the later, succeeding cultures.

The intention of this study was to check the feasibility of the implementation of the newly synthesized biopolymeric materials for sizing of cotton yarn, based on the basic principles of chemical modification and practical verification in industrial conditions. The paper includes acid hydrolysis of corn and potato starch up to the controlled molecular weight with graft–polymerization of acrylamide, acrylic acid, 2-hydroxyethyl methacrylate and methacrylic acid on hydrolyzed starch for improving the hydrophilicity and solubility, capability of forming the film, increasing the potential of the adhesive potential, avoidance of retrogradation phenomena, etc. The objectives of the research were primarily related to the establishment of appropriate, environmentally–friendly and productive systems for sizing cotton yarns through the analysis and systematization of a large number of synthesis methods in conjunction with the characterization and properties of the graft copolymer. The results showed the following: (a) benzoyl peroxide initiator was very successful in grafting of acrylamide, azobisisobutyronitrile initiator in grafting of acrylic acid and 2-hydroxyethyl methacrylate, while the initiator potassium persulfate was the best in the grafting of methacrylic acid on size; (b) contribution of hydrolysis and grafting, the percentage of grafting and grafting efficiency, the conversion of monomers to polymer, molar mass as well as FTIR analysis confirmed that this is a new product made of starch and vinyl monomers; (c) after impregnation of single yarn and double yarn (type of yarn), it was found that coarse single yarn as well as double yarn absorb or bind to themselves more size in all cases compared to the finer yarns, which is associated with a higher volume in scope, looser structure, as well as a smaller number of turns; (d) after sizing, warp becomes more uniform in thickness, which is the effect of size deposit mass to yarn when different types of deformity along the length of the yarn are "fixed"; (e) mechanical properties change during the impregnation with various sizes, tensile strength of analyzed yarns is increased and partial elongation is decreased; (f) values for the abrasion in cycles go beyond the raw yarn in all cases; (g) yarn hairiness decreases with sizing, which increases the smoothness and reduces friction; (h) micrographs of yarn processed with new sizes have smoother structure with fibers stuck together to each other, and a large degree of parallelism in the direction of the longitudinal axis of the yarn; (i) with desizing in conventional washing there is a significant removal of the applied starch copolymer, while the use of ultrasound in washing caused the greatest degree of size removal from yarns; (j) recycling of applied sizes after desizing is possible because those are water–soluble compounds, similar products for sizing must first be decomposed in order to perform the desizing and therefore they cannot be recycled; (k) using a statistical one–way Anova analysis and multiple linear regression, the advantage of the new derivatives of starch as potential means for the sizing of cotton yarn of different fineness and string was confirmed, what stands out is the copolymer of starch and 2-hydroxyethyl methacrylate as a potential and highly efficient size; (l) practical assessment of sized warp in weaving proved usability and potential of new size.
