    Development of High Count Repurposed Yarns from Pre Consumer Textile Waste

    Ananya Mitra Pramanik , Anjali Agrawal

    Currently, pre consumer wastes are used to create low count repurposed yarns (RY) which has a limited usage in the floor covering industry. A previous research paper had established that there was a need to reduce the thickness of the existing repurposed yarns (RY) to increase its usage. Therefore, the objective of this present study was to undertake design intervention on the existing RY to change its count. Wider usage of RY can divert maximum pre-consumer textile waste from reaching the landfills. The count of the existing RY procured from Bhadohi was 0.23Ne which was made finer by using the manual spinning method. The methodology used in this study was of practice based research through which solutions were designed in the existing repurposed yarns to create higher count yarns and hence, make it suitable for generic end use. Two different counts of yarns were created in this research study, which were then characterized for their tensile strength, wash, and rub and perspiration fastness. The results of the characterization were compared to the existing RY. The modified repurposed yarns (MRY) were found to be 0.44Ne and 0.98Ne count which was much higher than the existing yarns. The tenacity of the yarns was mostly found to be improved in comparison to the existing RY yarns. Fastness properties of the yarns were also found improved in comparison to the existing yarns.

    Nano science and technology research

    Taher Kaddar

    Most of us involved with textiles recognize the tremendous progress that is being made in nano textile science and engineering over the last decade. Journal of Textile Science & Engineering (JTESE) has been promoting this important research area with papers and editorials in the past, but more needs to be done. There is a large body of textiles related nano research that is suitable and indeed encouraged by the JTESE in nano coatings and membranes for high performance clothing for example, functionalisation of nano fibres and mats, medical nano textiles such as smart dressings, slow release and others. Nanotechnology deals with the creation of functional materials, devices and systems through the control of matter at the 1–100 nm scale or to put it in context about 80,000 the size of the human hair. For the first time material scientists have the opportunity to design and engineer materials and devices by the “bottom up” so-called approach, by manipulation of matter near the atomic scale and as such having the opportunity to be in precise control of their behavior. It is therefore revolutionizing this multidisciplinary field which marries together the fundamental sciences of physics, chemistry and biology

      Analytical method using gamma functions for determining areas of power elliptical shapes for use in geometrical textile models

      F. Gommer a1, L.P. Brown2, K.C.A. Wedgwood3

      Textile models are often assumed to have homogenous and well defined cross-sections. For these models, the use of a power elliptical cross-sectional shape has been found to be beneficial as different shapes can be created, e.g. lenticular, elliptical or rectangular, with a single function. The cross-sectional area of a power ellipse is usually determined numerically as the analytical determination of the cross-sectional area is not straightforward. This short communication presents an analytical solution for this shape.

            The straightforwardness of snatching a clothing or dishwasher case and throwing it into the machine has settled on them a mainstream decision for some purchasers for almost 10 years. Cleanser and different fixings are bundled inside a dissolvable plastic covering called polyvinyl liquor, or PVA. This engineered polymer, utilized since the mid-1930s, is water-solvent and falls to pieces during the wash cycle, delivering the cleanser. Many organizations guarantee PVA is biodegradable. While it very well may be completely biodegradable, explicit conditions are required for it to totally biodegrade. These conditions are regularly neglected. Likewise, as it disintegrates upon contact with water, it can deliver ethylene, which is a petroleum derivative based compound. This got two Arizona State University scientists thinking about what befalls PVA when it arrives at wastewater treatment plants. "There are extremely severe conditions required for PVA to biodegrade, and this isn't met inside traditional water treatment in the U.S.," said Charlie Rolsky, co-first creator of another examination distributed in the International Journal of Environmental Research and Public Health. "We can take a gander at the writing and survey the amount PVA is separating, and in which part of the wastewater treatment plant. We can consolidate that with how much wastewater is created in the U.S. also, the number of these clothing and dish units are utilized in the U.S. every year. "At the point when we set up these pieces, we can project the amount PVA goes untreated and is delivered into the climate," said Rolsky, a postdoctoral scientist with the ASU Biodesign Center for Sustainable Macromolecular Material and Manufacturing. The investigation, distributed in June 2021, shows that as much as 75% of PVA goes untreated in the U.S. every year. That adds up to around 8,000 tons of the plastic material being delivered yearly onto land and into streams the nation over.

            By estimating an individual's developments and stances, shrewd garments created at MIT CSAIL could be utilized for athletic preparing, recovery, or wellbeing observing for senior consideration offices.

            As of late there have been energizing forward leaps in wearable advancements, as smart watches that can screen your breathing and blood oxygen levels. However, shouldn't something be said about a wearable that can recognize how you move as you do an actual work or play a game, and might actually much offer criticism on the most proficient method to work on your procedure? Also, as a significant reward, imagine a scenario where the wearable were something you'd quite be wearing, similar to a shirt of a couple of socks. That is the thought behind another arrangement of MIT-planned apparel those utilization exceptional filaments to detect an individual's development by means of touch. In addition to other things, the specialists showed that their garments can really decide things like in case somebody is sitting, strolling, or doing specific stances. The gathering from MIT's Computer Science and Artificial Intelligence Lab (CSAIL) says that their garments could be utilized for athletic preparing and restoration. With patients' consent, they could even assistance latently screen the soundness of occupants in helped care offices and decide whether, for instance, somebody has fallen or is oblivious. The scientists have fostered a scope of models, from socks and gloves to a full vest. The group's "material hardware" utilizes a blend of more normal material filaments close by a modest quantity of uniquely designed useful strands that sense pressure from the individual wearing the article of clothing. As indicated by CSAIL graduate understudy Yiyue Luo, a critical benefit of the group's plan is that, not normal for some current wearable hardware, theirs can be joined into conventional enormous scope clothing creation. The machine-weaved material materials are delicate, stretchable, breathable, and can take a wide scope of structures. "Generally it's been difficult to foster a large scale manufacturing wearable that gives high-exactness information across countless sensors," says Luo, lead creator on another paper about the task that has been distributed in Nature Electronics. "At the point when you make heaps of sensor clusters, some of them won't work and some of them will work more regrettable than others, so we fostered a self-rectifying instrument that utilizes a self-directed AI calculation to perceive and change when certain sensors in the plan are misguided." The group's garments have a scope of abilities. Their socks anticipate movement by taking a gander at how various arrangements of material impressions correspond to various postures as the client changes starting with one posture then onto the next. The full-sized vest can likewise identify the wearers' posture, action, and the surface of the reached surfaces. The creators envision a mentor utilizing the sensor to break down individuals' stances and give ideas on progress. It could likewise be utilized by an accomplished competitor to record their stance so novices can gain from them. In the long haul, they even envision that robots could be prepared to figure out how to do various exercises utilizing information from the wearable’s. "Envision robots that are as of now not tactilely visually impaired, and that have 'skins' that can give material detecting actually like we have as people," says relating creator Wan Shou, a postdoc at CSAIL. "Attire with high-goal material detecting opens up a ton of energizing new application regions for scientists to investigate in the years to come.

              The two Categories of leather alternatives

              Stephen J Russell

              The two Categories of leather alternatives included Vegan Leather (mostly made with plastic coatings) and Eco-Friendly Leather alternative (materials that

              Are “good” for the environment).

              With a convenience sample (N=11) of fashion design students/consumers, data was collected via questionnaire with open and closed-ended

              Questions, including questions about the participant’s knowledge and experience with purchasing leather and leather alternative products. Their

              Knowledge of leather processing was also questioned.

              The key results were that participants had various perspectives and attitudes about using leather and leather alternatives. Most had not heard of

              More than one of the eco-friendly leather alternatives that was listed on the questionnaire and most did not have knowledge of the leather producing

              Process. Those who had taken textiles courses previously stated that they covered leather and/or its alternatives either very little or not at all.

              The findings have implications for various stakeholders including leather alternative manufacturers, fashion programs and instructors, textbook

              Producers and retail establishments. A need was discovered to define specific terms to explain the differences between leather alternatives that

              Use plastic toxins vs. leather alternatives that were better for the environment. Leather alternative terms were used interchangeably which could

              Confuse consumers with what they were actually purchasing.

              The conclusion was that leather alternative manufacturers could use these findings to see the need to better educate their consumers. Some of

              The education that could be included is exposure to specifics about their products in terms of construction and components used in relationship to

              Environmental and sustainability concerns. This specific information is not widely available to consumers and more education is necessary

                Robel Legese Meko

                Extensive use of synthetic dyes in textile industry has created a major pollution problem. Among various treatments, adsorption has been considered as a better process due to its effectiveness of removing color from wastewater. In this present work, the efficiency of activated carbon prepared from corn stalk for removal of reactive dye from textile wastewater was studied. Corn stalk was chemically activated with KOH, followed by carbonizing in a muffle furnace. The carbonized corn stalk was characterized by SEM and FTIR spectroscopy. Adsorption of three reactive dyes were carried out by preparing dye samples in laboratory and taking dye wastewater from BDTSC. Adsorption was carried out under the control of three different factors namely contact time, adsorbent dosage and pH. Optimum time, pH and adsorbent dosage for adsorption process were found to be 60 minutes, 3.8 pH and 4 g/L respectively. Using those optimum operating parameters, the adsorption capacity of prepared activated carbon for Reactive yellow-145, Reactive red-2, Reactive blue-19 and wastewater taken from BDTSC was 96.9%, 95.5%, 97.1% and 88% respectively. Langmuir and Freundlich adsorption isotherm models were used to simulate the equilibrium data for the adsorption process. The result indicates that the adsorption process best fits with Freundlich isotherm. The produce activated carbon was also shown a reduction of BOD, COD, TDS, TSS and turbidity.

In this research, silica aerogel/polypropylene (PP) nonwoven fabric composite with desirable properties was synthesized via a two-step sol-gel process through immersing the PP nonwoven fabric into silica sol. After in situ gelation, silica phase was hydrophobized with hexamethyldisilazane, and the composites were dried at ambient pressure method. Scanning electron microscopy (SEM), DSC, TGA were used for the characterization of the composites. The contact angle and heat conducting performance of the composites were also determined. The results show that silica aerogel particles were efficiently covered the surface of the PP non-woven fabric and completely filled the micron size pores of the nonwoven fabric leading to a stronger hydrophobicity and higher thermal insulation performance in the aerogel composite. The findings in this study are significant and can be used for further research in aerogel-treated nonwoven fabrics.

                The Role of Binders and Its Chemistry in Textile Pigment Printing

                Asaye Dessie,Bezaneh Eshetu

                This review paper presents the chemistry of binders and their action in pigment printing of cellulosic textile substrate.  Printing of textile materials is probably best described as an industrial art, having a long history and an assured future. Textile printing is the most versatile and important of the methods used for introducing color and design to textile fabrics. In pigment printing, insoluble pigments, which have no affinity for fibers, are fixed on to the fibers with binding agents or binders.  In textile printing, dyes or pigment are transferred to textile fabric by printing pastes. Binders are the mechanism used to keep the color on the fabric when using pigments for printing textiles. The choice of binders will always depend upon the final fastness requirements as well as the cost requirements of the process. Almost all the binders used in textile pigment printing are the addition polymerization products. The binder is a film forming substance made up of long chain macromolecules, which when applied to the textile together with the pigment , produce a three dimensionally network. Different binders were also developed for the purpose, resulting finally in the use of water- in-oil, and oil-in-water emulsions. This greatly accelerated the use of pigments in textile printing and then pigments have become major coloring matters used in printings. This paper review gives more emphasis on the need and functions of binder in pigment printing and also the chemistry of binders and its action in fixation of the pigment onto the textile substrate.

                Rare earth salts mediated improved rubbing fastness for Indigo dye

                Padma S Vankar, Archana Gangwar

                Indigo dye though rich in blue colour has poor affinity for cellulose cannot penetrate too well and thus it mostly remains at the surface of the fabric after dyeing. This phenomenon is called ring dyeing. Such ring-dyed materials have poor rubbing fastness towards dry and wet test methods. Our objective in this paper has been to use rare earth (RE) salts to overcome the rubbing fastness problem. The RE metals used in this research work are Cerous sulphate, Lanthanum chloride and Yttrium chloride.

                COPPER-COATED UNIFORM FOR HEALTH CARE PROFESSIONAL COULD HELP REDUCE CROSS INFECTION IN HOSPITALS

                Kumar Vijay, Kumawat Nitesh, Ramawat Yashawant, Sharma Ankur

                Nosocomial Infections are a more common health issue in each health care setting across the worldwide. Pathogenic flora spread throughout medical and surgical care facilities on surfaces and uniforms, contributing to damage both of human life and money. These issue turn into worse still after increase of drug resistance in most of the strains, which is rendering the broadspectrum antibiotic more powerless. So we require another ways instead of antibiotics. Precious metal is also a key role in great antibacterial and antimicrobial agents such as gold, silver and copper, which have superb antimicrobial properties. Gold or silver are more expensive for use against infection as compare to copper. Copper is good option that we can use in view of cost as well as copper having very good at killing power for pathogenic flora.
