Abstract: Identifying Studied sample acacia species selected and collected from Bekele Molla Hotel Avenue, Chamo Kebele, Arba Minch under convenient random sampling method. Tannins extracted using the solvents such as water (at 60 & 900C), methanol (at 900C) and its 1:1 mixture (at 900C) by employing Soxhlet extraction. Extracted crude tannins was separated and purified under vacuum distillation. The photochemical screening and quantitative determinations of sample carried out. Furthermore, the sample of tannins characterized by employing U-visible and FTIR spectroscopic studies. Methonalic extract consist moisture content and % yield about 17.86±0.51 % and 52.55 %. The results of Uv-visible and FTIR spectroscopic studies were supporting that the sample of Acacia xanthophloea has tannins and flavonoids. Thus, this study reveals and confirmed that the methanol is more suitable solvent for extraction of tannins over than water.

2. Studies on Effect of Alkali Treatment on Mechanical Properties of Multi-Layer Viscose / Flax Composites.
Author(s) : Gnanavel P

Abstract: Composite fabrics consists of numerous structural components and are united into a single structure. The applications of composite fabrics are versatile and it is depending upon the constituent materials and the mechanical properties are changed by the constituents. The study of mechanical properties of composite fabrics such as flexural rigidity, tensile strength, impact became very essential to understand the suitability of application in various areas. In this study the various mechanical properties are studied by treating with alkali and resins. The results of mechanical properties were analyzed and compared with treated and untreated. The results show that alkali treated fabrics have enhanced mechanical properties.

3. Improving Process Performance of Cotton Spinning by Using Statistical Process Control Techniques
Author(s) : Dereje Girma and Omprakash Sahu

Abstract: Identifying the presence and understanding the causes of process variability are key requirements for well controlled and quality manufacturing. This pilot study demonstrates the introduction of Statistical Process Control (SPC) methods to the spinning department of a textile manufacturing company. The methods employed included X Bar and R process control charts as well as process capability analysis. Investigation for 29 machine processes identified that none were in statistical control. Recommendations have been made for a repeat of the study using validated data together with practical application of SPC and control charts on the shop floor and extension to all processes within the factory.

4. Development of Therapeutic Cushion Using Chrysopogon Zizanioides (Vetiver) and Bamboo Fabric
Author(s) : B.Jeyanthy, S.Karpagam Chinnammal, R.Karthikselvam

Abstract: Textile is the key component of every human life from birth to last rights. In the recent decade, textile sectors have shown tremendous growth through improved technology from raw materials to product design and manufacturing process. These extraordinary developments provide a path to find an innovative solution to the medical sector especially in the field of therapeutic textiles. This project is a small initiative to confer a solution for particular workforce such as truck drivers who are suffering from hemorrhoids disease. The main aim was to find an innovative therapeutic textile solution for this ailment based on ancient method of herbal treatment

5. The Extraction of Fibre from Sisal Plant Leaf and Study of Comfortable Chemical Properties for Apparel Use
Author(s) : J.Ethiraj, Muktar Kassim, Erit Salahadin

Abstract: In vision of recent worldwide environmental issues, scientists have begun to show interest in developing the full potential of natural fibers and their assorted uses. Historically most of the methods used for the extraction of the sisal fiber inclusively the natural retting and mechanical process is not efficient in the removal of fibre compounds. In this study is related to how the impurities are removed from the fiber for apparel use. The alkali treatment, acidic treatment and treatment with varying solution of sodium salts is performed. The extractions of fibre have two stages, preliminary stage and laboratory stage. Primarily attaining maturity, sisal leaves was harvested manually by cutting from the leaf base with a sharp specialized crescent like knife having long handle. The harvested the fibres were systematically washed with distilled water and dried in a vacuum oven pre-set at 80ºC for 24 hours after which raw fibres were sampled. They were then treated with diethyl ether: petroleum ether: Ethanol (2:2:1), followed by ethanol. After the extraction process was completed, the length, diameter, moisture adsorption properties, physical shape, color, the visual appearance of fibre after treated with NaOH and some other physico-chemical properties of fibre will be evaluated.

6. Turn-On Eco-Quotient, A Step to Sustainable Fashion
Author(s) : Mohana Priya R

Abstract: The textile and fashion industry are a huge industry with the multiple sectors which use multifold resources to meet the needs of the customers. The fast fashion has ended up with more environment threats. The sustainable fashion is the solution to minimize the ecological impacts and reduce the resources and wastes. It focuses on how the product can stay during its entire life cycle with less impact to the environment. It is big challenge to be sustainable textile and fashion sector because of non-vertical business model.
