The demand of cotton is increasing but its low production rate cannot fulfill the world requirements. The increase in cotton demand has augmented the production of regenerated cellulosic fibers. Furthermore, cotton has proved to be unsustainable because of the use of huge amount of fresh water, pesticides and insecticides. The purpose of this work is to find out the suitable blend/blends of regenerated fibers so as to replace 100% cotton fabrics. Therefore, mechanical and comfort properties of Tencel fabrics blended with other regenerated cellulose fibers have been compared with 100% cotton to achieve the equivalent or even better end properties. Hence, cotton, viscose, Tencel, modal, and bamboo fibers were taken. Plain woven blended fabrics of 100% cotton and 50:50 blends of Tencel with other regenerated fibers were prepared from normal yarn count of 20 tex. The mechanical properties (warp-wise and weft-wise tensile and tear strengths, pilling, and abrasion resistance) and the comfort properties including air permeability, moisture management properties, and thermal resistance were evaluated. It is found that Tencel blended fabrics show better results than 100% cotton fabrics. Therefore, it is concluded that Tencel blended with these regenerated fabrics can be used to replace 100% cotton fabrics.
The research in textiles is being driven by ecology, economy, and functionality. Therefore, the present research is focused on the development of multifunctional textiles that consume minimum energy during their processing, eco-friendly chemicals for functionalization, and use short processing steps. Eco-friendly cross-linkers such as butanetetracarboxylic acid and zinc oxide nanoparticles are used to impart wrinkle recovery, antibacterial activity, ultraviolet (UV) protection, bending rigidity, and antistatic properties to cotton fabric just in one step. The treated fabric has been characterized with Fourier-transform infrared spectrophotometer, scanning electron microscope, and X-ray diffractometer. Wrinkle recovery, tear strength, antibacterial activity, UV protection, and antistatic properties were tested with AATCC 66-1990, ASTM D 1224, AATCC 147, AATCC 183, and UNI EN 1149, respectively. The treated fabric shows excellent functional properties up to 20 washing cycles.
Acacia nilotica is an important agroforestry specie, which is used in both compact and linear forms. The objective of the current study was to evaluate the effect of compost on the growth performance and biomass production of A. nilotica. Completely randomized design (CRD) was used to analyze the variations among several growth morphological traits. Two parallel trials, pot trial (seedlings), field trial (saplings) were conducted simultaneously. Compost and litter mixture were applied in mentioned trials. Following treatments were used: T0 – control; T1 - 25% of compost and 75% of nursery soil; T2 - mixture of 50% nursery soil and 50% compost; T3 - mixture of 75% compost and 25% of nursery soil; T4 - where 100% compost was applied. Increase in plant growth was observed with the increases in the amount of compost mixture. In field trial maximum plant height, shoot length, root length, rootshoot ratio and biomass production was observed when 100% compost level was applied, while minimum was observed without any compost appli-cation. In pot trials, the maximum plant height, rootshoot ratio and biomass production was recorded when 75% compost level was applied. Overall, Acacia performed better with 100% of compost application in field trail and 75% of compost application in pot trial. The results of this study demonstrated the positive effects of compost on the growth of Acacia. The seedling development was improved considerably with different levels having greater percentage of organic fertilizer and it was concluded that compost improves soil fertility and it should be used as organic fertilizer in farming and forestry practices for improving crop growth and yield.
