Biomass pigments have been regarded as promising alternatives to conventional synthetic dyestuffs for the development of sustainable and clean dyeing. This investigation focused on in situ dyeing of fabrics with biopigments derived from tea polyphenols via non-enzymatic browning reaction. The average particle size of dyed residual liquor with natural tea polyphenol was 717.0 nm (ranging from 61...
Seven reactive dyes judiciously selected based on chemical structures and fixation mechanisms were applied at 2% of of shade on amidoximated acrylic fabrics. Amidoximated acrylic fabric has been obtained by a viable amidoximation process. The dyeability of these fabrics was evaluated with respect to the dye exhaustion, fixation, and colour strength under different conditions of temperature and ...
Smart garments, which can capture electrocardiogram signals at any time or location, can alert others to the risk of heart attacks and prevent sudden cardiac death when people are sleeping, walking, or running. Novel wearable electrodes for smart garments based on conductive chitosan fabrics were fabricated by electroless plating of silver nanoparticles onto the surfaces of the fibers. The elec...
Imagine the stories we would tell if we could construct media experiences as easily and playfully as we now use spoken language. Today, storytelling approaches are transitioning due in part to the abilities of small, mobile networked devices to capture, manipulate, share, exchange and publish visual and sound sequences. This paper explores a new paradigm we call the ‘media fabric’ -a vast colle...
what is called the problems of tehran metropolis now a days, is deep- rooted in the policies ofurban planning in our country. since not far past up to now, immigration from all over the country to tehran, irregular growth of urban population, inconsistency with urban infrastructure development, environmental pollution and low quality of living areas, erosion of self -growing fabric in most area...
The rapid increase in primary enrollment seen in many developing countries might further worsen the poor schooling quality often found in these countries. I estimate the effect of enrollment growth following the removal of primary school fees in Tanzania and find that it led to sizeable increases in the pupil-teacher ratio and a reduction in observable teacher quality, but rule out a substantia...
respect and reverence for water and trees are institutionalised in many ancient civilisations due to socio-cultural traditions, values and beliefs. in iranian societies, respect for trees and water, separately and in composite form as gardens, is a well-known cultural value both before and after islam. therefore, the first part of this paper explains the value and importance of plants and garde...
In last few years’ different textile companies aim to produce the quality fabrics. Major loss of any textile oriented company occurs due to defective fabrics. So the detection of faulty fabrics plays an important role in the success of any company. Till now most of the inspection is done using human visual. This way is too much time consuming, cumbersome and prone to human errors. In past, many...
The polyester (100%), cotton (100%) and Polyester / Cotton blend fabrics (65 / 35; 50 / 50 & 35 / 65) were treated with sodium hydroxide followed by hydrophilic finishing and dyeing to impart hygroscopic and dyeing characteristics. Then the finished fabric was tested for k/s value, fastness properties, wetting behaviour, water retention, wicking behaviour and static charge respectively. The sod...
Analysis of the Restrictive Elements of China's Textile Industry in Upgrading Based on “Value Chain”
Our country’s textile industry is in the producing and processing field in the global value chain, so textiles’ added value is low and profit margins is narrow. Developed countries take up fields of high-grade fabrics production and advanced textile machinery manufacture. Because textile fabrics, textile machinery and equipment of China's textile industry fall behind developed countries, produc...
