Derivation of Yarn Package Radius Measuring System for Yarn Winding Machines

Decreasing waste materials through recycle has in the recent contributed to sustainable manufacturing in many textile industries for better resource utilization in textile mills. This has been given first priority in manufacturing, processing and finishing operations. Most of the time the yarn manufacturing and proper utilization of this material didn’t give attention in most companies. Especially yarn length variation of packages, weaving beams and copes have very critical impact on those companies which manufacture and utilize yarn products. This variation problem has great impact on their productivity and profitability. This paper describes the application of a new formula in the yarn packaging process and it is accomplished by derivation a new formula that can determine the radius of any package. The formula has integrated the basic characteristics of yarn and fiber including yarn diameter, yarn/ fiber density and mass of the yarn coiled on the cop. Finally we have concluded that package radius is the quadratic function of yarn density and package mass on the cope.

Electrospun Nanofibers for Drug Delivery Applications

Nanofiber systems with various composition and biological properties have been extensively studied for various biomedical applications. The electrospinning process has been regarded as one of the versatile techniques to prepare nano to microfibers. The electrospun nanofibers are being used especially in textile industries, sensors, filters, protective clothing, energy storage materials, and biomedical applications. In the last decade, electrospun nanofibers have been highly investigated for drug delivery systems to achieve a therapeutic effect in specifically targeted sites. Various drugs or biomolecules can be easily loaded into the electrospun nanofibers by direct or indirect methods. The proper selection of polymers (or blends of various polymers), drugs, solvents to prepare the composite nanofibers with desired morphology are the tools in enhancing the bioavailability, stability, and bioactivity of drugs.

Study of the oxidative degradation of industrial laundry effluent from jeans by chromatography

Textile industries activities can positively affect a city’s economy. However, those industries require a great deal of water and sheds high organic load into water bodies, causing a considerate environmental impact. As potential pollutant substances, the dye’s presence in textile effluents are recalcitrant and can change the chemical and physical properties. It also resists conventional treatments. The treatment based on advanced oxidation processes presents to be efficient on dye’s degradation, but it may generate secondary toxic compounds, therefore is necessary to use techniques to evaluate its toxicity after the treatment. This study evaluated a laundry effluent, both before and after the treatment using the photo - Fenton processes. Applying liquid chromatography, results have shown that the dye's degradation was higher than 90% and a COD decrease to 73%.

Fashion, Industry and Diplomacy: Reframing Couture–Textile Relations in France, 1950s–1960s

This article investigates the change in relations between Parisian haute couture and the French textile industry in the 1950s and 1960s. This study is grounded in the multiple changes that occurred between the two decades with the end of a state-sponsored and textile-backed aid to couture plan in 1960, the dematerialization of fashion in the 1960s and the advent of brands and licenses, and the waning of couture’s influence throughout the period. It cross-references archives from multi-stakeholder meetings between the state, couture, and textile representatives with the couturiers’ trade association archives and diplomatic archives to show how the changing fashion landscape impacted their interactions. This study shows that while the couture and textile industries drifted apart, the government’s interest in couture grew. This reframes the narrative on couture’s alleged influence as the spearhead of the textile industry while illustrating its wider prestige influence and its relevance to the state.

The COVID- 19 Impact on the Food and Textile Industry: Lessons Learned

The Covid-19 virus pandemic has crippled life as we know it. The virus is still spreading, and life is still not normal. Of course, various industries are crippled. Supply chains will need to become more resilient in the future to possible recurrence of incidents like the pandemic of Covid-19. In this article, we will present how the Covid-19 virus pandemic has affected the food and textile industries. We have reviewed what measures were made at the start of the pandemic and how these industries have adapted to them. We also reviewed how the measures will affect supply chains and how they should operate in the future to withstand possible recurring emergencies such as the Covid-19 pandemic. We also compared the benefits of local in global supply chains, because in food supply chains the issue needs to be addressed and the Covid-19 virus pandemic can encourage consumers to buy locally produced food. It turned out that the Asian textile industry is largely dependent on western countries and has fallen into a major crisis with a massive drop in orders.
