The washing and the special treatments (enzyme and/or pumice washing for aged look) on denim garments are the important parameters influencing cloth shade, color fastness and the fabric mechanical properties. The most commonly used indigo dyestuff for dyeing denim fabrics is the process of producing waste, consuming excess energy and wate. In this study, we made an attempt to reduce the environmental damage of denim dyeing processes by using nanocoating method. Indigo and reactive dyed denim fabrics were purchased from GAP Textile and used for obtaining nanofilm coated denim fabrics. Optifix E50 is used for cationic layers and Tanapur EP3027 is used for anionic layers. In the deposition process, denim fabrics were deposited with 10 multilayer films by using a padding machine for padding process and a modified open-width washing machine for continuous process. Scanning electron microscopy measurements were used to verify the presence of the deposited nanolayers. Colour fastness to washing, Colourfastness to Perspiration, Colourfastness to Water, Colourfastness to crocking and tensile strength were performed to examine the LbL process effect on the denim fabric properties. This study shows that continuous nanofilm deposition process can be used for enhancing color fastness properties of especially reactive dyed denimfabrics

In the paper / communication, the problem of electrostatic loading of textile fibers in the air pipes is being treated in an innovative way, occasioning explosive hazards. The thematic aspect approached is essentially required in mining security solutions in the underground exploitation of energy coal and coke in the Jiu Valley mines, where methane (CH4) and coal dust are found to form the grizzly atmosphere. It is specified that methane and coal dust in a concentration of 9.8% have the maximum devastating potential of explosion, with all the medical / deadly consequences among people. Observations show that synthetic fibers used in partial air tubes have low electrical conductivity and load significantly, electrostatically. The proposed variant of the authors is to resort to the choice of different textile fibers placed on the stack / range of electrostatic stresses.

Nowadays, the electronics are free of their rigid structures and become flexible. As a result of this structural transformation and minimization of electronic materials, they can be integrated into textiles as wearable devices. The sensors are one of the main structures of personalized wearable monitoring devices and they can be classified into physical, chemical, electrical and biological ones. The wearable electronic sensors are able to monitor majorly biomedical signals and other ambient variants. Gesture, body temperature, respiration, pulse, blood gas etc. are among the measured physiological parameters. The other monitored parameters can be defined as environmental variants such as ambient temperature, humidity, sound, gas etc. Different types of textile based sensors are used in wearable personalized devices using different conductive materials in order to measure the vital parameters. Metal coated fabrics, fibres containing metals or metal based additives, knitted and woven structures produced by using conductive yarns etc. can be used as textile based sensors. These sensor structures can be used in several fields such as medical, sport, artistic communities, military and aerospace. In this paper fabric, based wearable sensor types will be reviewed and a lso it will be focused on the recent advances in the field of these sensors and their usage areas.

MBBR (Moving Bed Biofilm Reactor) wastewater treatment technology relies heavily on the type of used HDPE (High Density Polyethylene) carriers, that use immobilized biofilm for the removal of organic and inorganic substances in the treated wastewater. Present work explored DSC (Differential Scanning Calorimetry) analysis on four novel variants of HDPE carriers. DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. The four novel carriers were composed of novel recipes of mixes of polyethylene with inorganic and organic compounds (patent pending), designed for greater microbial biofilm development. DSC analysis. DSC analysis was carried out in order to understand the behavior of the developed carriers, in various scenarios. High density polyethylene (HDPE) is a weak, semi- crystalline, thermoplastic polymer that is part of the polyolefin class. Analysis revealed that the temperatures at which the melting process of crystalline zones in the macromolecular structures occur, gradually decreases from the sample with only HDPE in composition to the one with addition of a mix of inorganic and organic compounds.

As the security precautions with respect to new standards for the furnishing textiles in big platforms such as concert, theatre halls have increased, flame retardancy has become one of the vital required property for drapery fabrics. However, those kind of additional treatment processes may lead to some differences in fabric properties such as friction which should be considered for the consumers. This study aims to evaluate the influence of using different ratio of flame retardant chemicals (g/l) on friction coefficient of drapery fabrics. For this purpose, nine types of fabrics composed of three different weft density (9, 11, 13 threads/cm) were selected. The warp yarns were selected as 400/200 denier/filament while the weft yarns were selected as 800 /200 denier/filament textured micro polyester yarns. Three levels for flame retardant (0, 60 and 90 g/l) were determined as the finishing processes. After the dobby fabrics were woven and exposed to finishing treatments; Friction coefficient values were recorded with Labthink Param MXD-02. ANOVA tests were performed in order to evaluate the significant effect of weft density and flame retardant chemical ratio on friction properties of drapery fabrics. Additionally, SNK tests were conducted for the comparison of means of friction values of drapery fabrics produced at different weft density also of the samples treated with different flame retardant chemical ratio. Experimental results revealed that structural parameters and the finishing processes were influential factors on the surface frictional characteristics of the fabrics. It was clearly observed that surface friction coefficients of drapery fabrics decreased due to the flame retardant process.

In the paper are presented several aspects concerning the composed methods for obtaining the materials capable of reducing the electromagnetic field by reflection/absorption. This study offers a structured presentation about advanced materials with electromagnetic properties that can be used to develop screens for electromagnetic attenuation. Besides is presented a factorial plan, selection of the eigenvectors, and analysis based on principal component. The ACP (principal component analysis) could solve the problems in selecting the optimal parameters used in experiments by reducing the complexity of the data and analyzing the variance of the variables from influencing factors. The investigation of the methods for electromagnetic radiation screens development is attractive due to the area of application, such as protection of the electronic designed for hospitals and special applications in the military area and in the field of transport, but also for the protection of the houses required due to the use of electronic devices (phones, PC, TV) involving mobile or Wifi/WLAN networks. In general, for the attenuation of electromagnetic radiation in the home can use paints, curtains, window blinds or carpets made of fabric, knitted or non-woven materials, with conductive yarns, fibers or polymeric film with adequate electroconductive or electromagnetic properties.

Digitization of cultural heritage, has started to play a major role in sustainability; also, old maps investigations can be a valuable source of information. These should be carefully handled by archive workers and those who are studying them, because mycological content can increase both human health and environmental problems. These, together with the conditions in which are stored can deteriorate the composition of the cellulose fibers, respectively the canvas fibers on which are glued. Samples were collected from old maps dating to 1895 and 1910 by specific means and methods in order to investigate their mycological content which revealed the presence of Penicillium ssp and Fusarium spp. Scanning electron microscopy - analysis (SEM) was done for the mentioned materials in order to determinate the deterioration of the fibers.

Samples were collected from old maps \u0000dating to 1895 and 1910 by specific means and methods in order to investigate their mycological content which \u0000revealed the presence of Penicillium ssp and Fusarium spp. Scanning electron microscopy - analysis (SEM) was\u0000done for the mentioned materials in order to determinate the deterioration of the fibers.","PeriodicalId":22214,"journal":{"name":"TEXTEH Proceedings","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86123335","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}
