Flame retardancy has been imparted to cellulosic cotton textiles using spinach (Spinacia Oleracea) juice (SJ). The extracted juice has been made alkaline and then applied a fresh to a bleached and premordanted cotton fabric. The flame retardant properties of both the control and the treated fabrics are analysed for limiting oxygen index (LOI) and vertical flammability. The study shows that the SJ treated fabrics have good flame retardant properties, with LOI of 30 for the SJ treated fabric, showing an increase by about 1.6 times compared to the control fabric with LOI of 18. As a result, the treated fabric does not catch flame and in the vertical flammability test, it burns with an afterglow and a propagation rate of 43.5 mm/min, which is almost 5 times lower than that observed with the control fabric. The mechanism of imparting the flame retardancy to the cotton fabric by application of SJ has been postulated and supported by SEM, EDX and char mechanism studies. The durability of the treatment to soap washing, rubbing, dry-cleaning and sunlight has also been studied. Besides, its application produces a natural green colour on the fabric, and no deterioration in other physical properties is observed. © 2017, National Institute of Science Communication and Information Resources (NISCAIR).

Finding alternative sources for natural and synthetic fibers is gaining momentum lately mainly due to the increased ecological and environmental concerns. Cornhusk (CH), an agricultural by product is generally being discarded as waste. However, it can be considered as an alternative source to conventionally used fibers due to its performance properties, low cost and large availability. In the present study, an effort has being made to develop green fabric using DREF spun CH fibers. To enhance the spinnability of CH, the fibers extracted from CH were blended with cotton and waste bamboo fibers and were further dref spun to produce core spun yarns. The fabric prepared using these core spun yarns was further tested for their physical and performance properties. It was found that CH fibers are compatible with cotton and bamboo and are processable on ring spinning machinery in the ratio of 30:70 (cornhusk/bamboo or cornhusk/cotton). Ring spun yarns of cornhusk/bamboo (CB) were observed to be coarser than cornhusk/cotton (CC) yarns and exhibited higher breaking load and breaking elongation values. Further, the dref spun yarns formed using CC as core and cotton as sheath exhibited lot of breakage with snarling defect. DREF spun yarn formed using CB as core and cotton and bamboo as sheath, was observed to be finer with higher breaking load and breaking elongation values as compared to CC core yarns. The fabric formed using these yarns showed difference in their physical and performance properties depending on the yarn being used as sheath. Fabric formed with CB core yarn with bamboo as sheath exhibited higher values of gsm, bending length, breaking load, breaking elongation, tear strength and better moisture related properties. On the other hand, fabric formed in CC core yarn with cotton as sheath exhibited better crease recovery properties. UPF of both the fabrics was found to be good i.e. around 35-40 making them suitable for apparel and furnishing purposes.

The demand for blackout fabrics in international market is increasing rapidly. Presendy, the ability of such fabric to cut/absorb light with its heat and insulation properties is checked visually by keeping the fabric against sun light and observe whether the light is passing through the fabric or not This type of evaluation is highly subjective; hence there is a need to develop an instrument for objective evaluation. Further, several manufacturers are interested to objectively measure the degree of "blackout" to satisfy the buyers. NITRA has developed an instrument (Patent no. 180/Del/2012 dt. 20/01/2012) which measures the light cutting/absorbing ability of fabrics and also provides useful information on heat cutting ability.

Polylactic acid and its blended yarns with various fibres have been converted in to woven fabrics. These fabric samples have been scoured and then tested for mechanical and flame retardant properties. The results indicate that the high alkaline scouring severely damages polylactic acid fibre. Therefore, mild alkaline scouring is done for further studies. The scoured fabric samples are tested for various flame retardant properties and compared with polyester blended fabrics. Results indicate that polylactic acid fibre is not suitable for upholstery, apparel and work wear in terms of flame retardant properties. © 2014 Indian Journal of Fibre & Textile Research.

Two sets of milkweed blended weft knitted fabrics have been produced and then tested for their constructional properties like courses/wales per inch, thickness, weight and tightness factor. These fabrics are also evaluated for thermal insulation (TI), water vapour permeability, air permeability and ultraviolet protection factor (UPF) properties and then compared with the only cotton and polyester knitted fabrics. The UPF and TI data of various blends of milkweed fibre with cotton or polyester have beed evaluated using one-way analysis of variance (ANOVA). Results reveal that the thermal insulation and ultraviolet protection factor of the milkweed blended fabric are higher than the corresponding properties of cotton and polyester fabrics, while the air permeability and water permeability properties are lower than the corresponding properties of cotton and polyester knitted fabrics. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).

An apparatus has been designed and developed to measure the light cutting/absorbing ability of curtains and to provide useful information on their temperature cutting ability. The apparatus is provided with various light sources with light, temperature and humidity detectors. The reproducibility of results, and effect of intensity of light (MBTL light source) on light and temperature cutting ability of six different fabric samples have been studied. The light and temperature cutting ability of the knitted fabric is found to be lower than that of woven and black out curtain fabric samples. © 2015, National Institute of Science Communication and Information Resources (NISCAIR).

Internationally NYCO is very well known combat uniform cloth in military and paramilitary forces and has completely replaced conventional p/c blends in USA and U.K military forces. Recendy NYCO fabric has been accepted by some Indian Para-Military forces. The late entry of this fabric in India is due to non-availability of nylon 66 fiber indigenously (one of the constituents for making NYCO cloth) and also lack of awareness and absence of technical know-how to manufacture the fabric. The present study highlights the manufacturing techniques of NYCO and p/c blended fabrics as well as Nylon and other Cellulose fibres (Excel). These fabrics are also evaluated for their performance.

The recent global environmental issues and inadequate raw fiber resources, have led the scientists to show interest in utilizing the full potential of natural fiber sources and their diverse uses. These natural fibers are present on earth since ages. But, the steady globalization and consumerism never provided the needed impetus to these fibers to be available for industrial and other potential usage. One such fiber is popularly known as Bagasse. It is the agricultural waste left after extraction of juice from sugarcane stalk. For years bagasse was treated as a waste and used for landfills. Later sugar mills started using it as a source of fuel. But, its low calorific value motivated the environmentalists and pollution control agencies to put measures to forbid its use as fuel alternative. This has led to innovation in the utilization of this agricultural waste in various applications. Being a cellulosic in nature, the application of bagasse in textile industry may be explored. This paper encompasses around the properties of bagasse as a potential raw material for various industries especially in textiles and the current status of developments in the diversification of its application.

There is revival of interest in organic cotton and naturally colored cotton without recourse to dyeing using harmful and polluting chemicals. Naturally colored cotton totally eliminates the process of coloration as this cotton has a colored gene present in the lumen of the fibre that imparts natural color to cotton as it grows and matures. Growers of naturally colored cotton may find less need for pesticides. Colored cottons have many insect and disease-resistant qualities and are drought and salt tolerant. Naturally-colored cotton is inherently flame retardant as the Limiting Oxygen Index (LOI) value of naturally colored cotton is higher than conventional white cotton. Cotton farmers at Coimbatore are showing keen interest in cultivating naturally colored cotton. This may lead to a ten-fold increase in the cultivating area which presently stands at around 700 acres. The research station at Gulbarga, Karnataka has already come out with brown and green cotton.

Corn husk waste biomass was collected from Aterna village, Panipat, Haryana and Azadpur Mandi, New Delhi. The collected biomass was manually cleaned and cornhusk fibre was extracted using alkalization process. The study revealed that higher concentration of sodium hydroxide, longer duration of treatment time and higher processing temperature adversely affect the fibre tenacity and fineness properties. The best results (Fibre denier: 78 and Tenacity: 1.38g/denier) were obtained when the biomass was treated with 0.5% sodium hydroxide for 60 minutes at 85°C. The heavy metal analysis indicated that cornhusk fibres are having lower metal content than the raw corn husk. To make fibres soft and pliable for spinning purpose, these were treated with modified polysiloxane micro emulsion and then blended with various fibres such as cotton, polyester and acrylic in blow room in varying proportions and finally converted in to yarn using hand spinning technology. The yarns so obtained were tested for various properties such as count, tenacity and elongation. It was observed that with the increase of corn husk percentage in the blended yarn, tenacity of the yarn decreases.
