Such a work system requires a great deal of responsibility in terms of quality, quantity, and the accurate and timely execution of tasks, which requires the quick and accurate response and extremely good psychomotor and visual skills of workers. This paper presents the process of determining the working method and normal times for the technological operation of runstitching women’s blouse collars, which includes the design of an ergonomically designed workplace, the selection and technical equipment of the universal sewing machine and the determination of the optimal work method and normal times using the Methods-Time Measurement (MTM) system. The research results obtained indicate that the technical equipment of a universal sewing machine has a significant impact on the structure of the technological sewing operation and the working method, i.e. the number of auxiliary manual technological suboperations. Improving technical equipment, i.e. increasing the number of automated functions used on a universal sewing machine, reduces the number of auxiliary manual suboperations, reduces the time required to perform the technological operation and increases work productivity.","PeriodicalId":22555,"journal":{"name":"TEKSTILEC","volume":"46 10","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41332328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This group includes elastic bandages, abdominal binders, posture correctors, corsets, recliners, etc. Elastic knitted bands are widely used in rehabilitation and prophylactic goods. This research studied the properties of elastic warp knitted bands that were made on an 18E gauge crochet machine. In order to reduce the product weight and to increase its comfort, a partial set (2-in/1-out) of elastomeric threads is used. This yarn is the main component of elastic fabric that aﬀ ects stretch properties and end-use. In the warp knitted band, the polyurethane thread is usually used as longitudinal inlay yarn, which is located between the loop’s overlap and underlap. In order to study the eﬀ ect of polyurethane pre-elongation before knitting on band properties, seven pairs of gears were used and elongation was varied from 280% to 395%. The weft ﬁ lling yarn connects the separate wales into the band. To prevent contact between polyurethane threads and the human body, the weft yarns were laid on both sides of the inlay yarn. The movements of weft guides were in opposite directions. In order to study the eﬀ ect of weft yarn diameter on cover factor and bands properties, 2 ends, 4 ends or 6 ends of 16.7 tex polyester yarn were used to achieve corresponding overall linear densities of 33.4 tex, 66.8 tex and 100.2 tex. It was concluded that the partial drawing-in of the guide bar with polyurethane thread facilitated a reduction of up to 20% in the basis weight of the elastic band, while ensuring suﬃ cient stretch properties. The impact of technological factors on the structural parameters and properties of the elastic band was established.","PeriodicalId":22555,"journal":{"name":"TEKSTILEC","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45292263","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is therefore important to examine its diff erent treatment methods. For this purpose, the isothermal adsorption of Reactive Black 5 dye on powdered activated carbon at 25(±1) °C and 45(±1) °C was carried out to determine the eff ect of initial dye concentration, contact time and temperature on the adsorption process. In order to investigate the mechanism of adsorption of Reactive Black 5 dye on activated carbon, kinetic studies have also been carried out. Experimental data were analysed using a pseudo-fi rst-order and pseudo-second-order kinetic models, as well as an intraparticle diff usion model. Standard Gibbs free energy values of the adsorption process were also calculated, while the morphological analysis of activated carbon before and after adsorption was performed using a scanning electron microscope. The effi ciency of activated carbon as an adsorbent for Reactive Black 5 dye is evidenced by the fact that more than 60% of dye is adsorbed after 30 minutes regardless of initial concentration and temperature. The experimental data also showed that adsorption is kinetically controlled assuming a pseudo-second-order process, and that intraparticle diff usion is not the only process that infl uences the adsorption rate. Negative values of standard Gibbs free energy indicate that the adsorption reaction is spontaneous, while a higher negative value for temperature of 45 °C compared to 25 °C shows that a higher temperature is more energetically favourable for the adsorption of Reactive Black 5.","PeriodicalId":22555,"journal":{"name":"TEKSTILEC","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2020-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47012781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Colours are not stored in our memories in their actual state and they can gradually be erased. This paper addresses the subject of short-term colour memory. The approach is based on an experiment where subjects observed a given colour for a certain period of time. The purpose of the research was to determine the relation between the reference colour, time delay and the accuracy in recalling of the colour from the subject’s memory. The colours studied in the research were presented with no association to bodies, shapes or textures. The main variables in the observing conditions were the basic colour parameters which defi ne the colour, i.e. hue, saturation and brightness. The analysis of the fi nal results showed that colour is not stored in our memories correctly and that it loses its basic parameters after 10 s. As the time delay increases, the accuracy of the colour impression in our memory diminishes. Colour is stored in our memory as clearer and more saturated. Bright colours are remembered as even brighter, while dark colours are stored as darker. The sensation of hue is generally stored very precisely, while the deviation in hue depends on the observed colour.","PeriodicalId":22555,"journal":{"name":"TEKSTILEC","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2019-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42945332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
