"Those who seek paradise on Earth should come to Dubrovnik and see Dubrovnik" (Bernard Shaw) The Faculty of Textile Technology, University of Zagreb, (Croatia), organised the 2nd International ...Textile Clothing & Design Conference "Magic World of Textiles", in the International Centre of Croatian Studies, in Dubrovnik (see Plate 1), from 3 to 6 October 2004.
Purpose - Today when the newest high-tech fibers and sophisticated material constructions are used for the production of sails, forming 3D sail shape from 2D sailcloth has still remained very ...primitive because classic sewing techniques are mostly used. Since, the clothing and technical textile industry has been recently using some of contemporary joining techniques (ultrasonic, thermal, high-frequency) replacing classic sewing, this paper seeks to investigate the possibility of ultrasonic welding in the production of sails, and the strength of obtained bonds.Design methodology approach - Concerning the aim, sails were made employing the classic and modern (ultrasonic) joining technique whereby bonding parameters such as amplitude and welding speed, geometry of anvil wheels were varied. Objective quality evaluation of the bond made in such a way, was performed in order to be more exact about its strength.Findings - Based on the obtained results it has been concluded that ultrasonic welding may successfully replace the classic sewing of sails, selecting an anvil wheel with suitable engraving and optimal parameters of welding (speed and amplitude).Practical implications - Selection of optimal welding parameters not only increases the sail's bond strength in comparison with classic seam, but also provides sail air impermeability, being one of the basic aerodynamic requirements for sail making.Originality value - This paper has presented the novel and successful approach in 3D sail shape forming from 2D sailcloth.
Ergonomics is a scientific discipline that explores the interaction between man, working systems and environment. Persons engaged in work activities should be protected according to workplace safety ...regulations by means of appropriate clothing, footwear and equipment specifically designed to meet ergonomic requirements. Protective clothing, footwear and equipment should be designed and engineered in such a way that their size and shape follow the dimensions and shape of the user’s body. In order to achieve this, it is necessary to make static and dynamic measurements of the user’s body. Based on static and dynamic anthropometry we have identified ergonomically favourable positions for pockets and zippers and the optimum length of sleeves, jackets, trousers, overalls, etc., as well as ergonomically favourable positions for incident-related equipment (e.g. devices for maintaining radio connections, lamp, breathing apparatus, etc.). In addition, it was established that some garments should overlap in order to avoid injury due to exposure of body parts. The paper provides examples of functional clothing designed for protection against heat and fire. The examples meet ergonomic requirements by identifying favourable pocket and zipper positions and sizes as well as by ensuring that some parts of protective clothing overlap to provide safety and protection. The paper also describes the method used for testing the ergonomic requirements of protective clothing and equipment, and presents the results of the survey that measured fire fighters’ satisfaction with this kind of protective clothing. The survey was conducted in three public fire brigades – two in Zagreb (Centre and Dubrava) and one in Karlovac, as well as two volunteer fire brigades (Dubrava and Karlovac).
SAŽETAK: Ergonomija je znanstvena disciplina u sklopu koje se istražuje interakcija između čovjeka, radnih sustava i okoline. S obzirom da čovjek obavljajući radne aktivnosti u svrhu zaštite na radu nosi odgovarajuću odjeću, obuću i opremu, ona treba biti oblikovana u skladu s ergonomskim zahtjevima. Zaštitna odjeća, obuća i oprema treba biti dizajnirana i projektirana tako da veličinom i oblikom što bolje prati dimenzije i oblik tijela korisnika, pa je potrebno napraviti statičke i dinamičke izmjere tijela korisnika. Na temelju statičke i dinamičke antropometrije ljudskog tijela mogu se utvrditi ergonomski povoljne pozicije džepova i patent zatvarača, duljine rukava, jakni, hlača, kombinezona i sl., ali i ergonomski povoljne pozicije opreme koja se upotrebljava tijekom akcidentnih situacija (npr. uređaj za održavanje radioveze, svjetiljka, oprema za zaštitu dišnih organa i sl.). Osim toga, dijelovi zaštitne odjeće međusobno se trebaju preklapati kako ne bi došlo do ozljeda zbog nepokrivenosti pojedinih dijelova tijela. U radu su prikazana pojedina rješenja funkcionalnog dizajna odjeće za zaštitu od topline i plamena koja su u skladu s ergonomskim zahtjevima, ergonomski povoljnim pozicijama i veličinama džepova i patent zatvarača, te se pojedini dijelovi zaštitne odjeće međusobno preklapaju i na taj način osiguravaju siguran rad. Također su opisani postupci testiranja ergonomskih zahtjeva zaštitne odjeće i opreme, te su prikazani rezultati provedene ankete o zadovoljstvu vatrogasaca interventnom zaštitnom odjećom kojom se koriste tijekom obavljanja radnih aktivnosti. Anketa je provedena u tri javne vatrogasne postrojbe - JVP grada Zagreba (Centar i Dubrava) i JVP grada Karlovca, te u dva dobrovoljna vatrogasna društva (DVD Dubrava i DVD Karlovac).

Purpose - The equipment for computerised measuring of electrical power and energy is presented, adapted to the needs of investigating processing parameters of garment sewing operations.Design ...methodology approach - The method of measuring the energy necessary to run the sewing-machine driving electrical motor is also presented, correlated to the stitching speed in joining a straight seam in a single, two, or three, segments. Electrical energy consumption is analysed as dependent on the stitching speed, varying the number of stitches in the seam.Findings - The investigations described have shown the impact of the method of work applied and the effect of the changes in garment sewing operation in processing parameters on the level of electrical energy consumed by the sewing-machine drive electrical motor. A new measuring method has been introduced in garment engineering, aimed at predicting electrical energy consumption in garment sewing operations, thus opening a completely new field of investigation in the area of garment technologies.Originality value - A method of calculating the energy processing parameters of sewing operations.

Korisnici zaštitnih odjevnih sustava različitih zanimanja (vatrogasci, pripadnici civilne zaštite, vojnici, radnici na palubama nosača zrakoplova i naftnih platformi, radnici u kotlovnicama, itd.) su ...tijekom obavljanja svojih radnih aktivnosti izloženi raznim vanjskim utjecajima kao što su djelovanje topline, vatre, vode, statičkog elektriciteta, kemijskih sredstava, a također rade u uvjetima smanjene vidljivosti uz povećani fizički napor. Zbog opasnosti od pojava opeklina i drugih mogućih povreda te za zaštitu njihovog zdravlja, od osnovnog značenja su odjevni sustavi s cjelokupnom opremom za zaštitu od topline i plamena koji ujedno utječu na njihovu učinkovitost pri obavljanju radnih aktivnosti. U radu je dan pregled zaštitne odjeće za vatrogasce i zahtjeva koje je potrebno zadovoljavati kako bi takva odjeća pružila odgovarajuću zaštitu i udobnost tijekom nošenja. Prikazani su zaštitni odjevni sustavi za vatrogasce, te materijali koji su osnovni gradbeni element višeslojne odjeće za zaštitu od topline i plamena. Istaknuta je i činjenica, da je osim optimalne zaštitne opreme jako bitna i određena razina vještine vatrogasaca te njihove psihofizičke sposobnosti kod obavljanja rada u akcidentnim situacijama.
Prikazan je uređaj koji može kontrolirano puniti, održavati tlak i prazniti ekspandirajuće komore obuće i odjeće stlačenim zrakom do željenog tlaka u određenom vremenskom intervalu pri čemu ima ...mogućnost internog mjerenja i prikaza izmjerenih vrijednosti na displeju uređaja i k tomu još i eksternog mjerenja tlaka zraka u komorama u ovisnosti o proteklom vremenu punjenja s pomoću vanjskog osobnog računala kako bi se mogli prikupljati, pohranjivati, analizirati, statistički obrađivati i vrednovati ekspanzijska i druga svojstva komora.
