    96-101The effect of two softeners (Sapamine® OC and Ultratex® ASG) on physical properties of BTCA finished cotton fabric has been studied. Bleached cotton fabrics are treated with 1, 2, 3, 4-butane tetracarboxylic acid (BTCA) followed by finishing with a cationic and a silicone softener by conventional pad-dry-cure method. Properties, such as crease recovery angle, absorbency, whiteness index, tensile strength, moisture regain, surface morphology and crystallinity of the finished fabrics, have been evaluated. The crease recovery angle of the finished fabrics increases from 154° to 257° after treatment with BTCA and further increases to 266° after BTCA+silicone softener based finishing. The absorbency of cationic softener finished fabric is found to be higher than that of silicone softener finished fabrics. Tensile strength reduces after BTCA finishing by more than 50%, and about 17% softeners is recovered. Scanning electron microscope images show smooth ridges and surface characteristics of cotton fibres in BTCA treated samples as well as deposition of softener on the fibre surface in cationic and silicone softener finished fabrics

    In today?s world more than eighty percent people uses the smart phones. As the need increases the misuse of the cell phone also increases. Anyone can distrust or cheat other or suspicious of others activities. There may be loss of an important data in the big organizations due to the employees. Many criminal activities have increased in organization and teenagers are misusing the smart phones. So for the security purpose in the large organizations and to control the activities of the employees and the teenagers, software can be used which keeps the log files in a single mobile with its date and synchronize daily with restricted area in corporate with cloud

    Effect of different mercerization techniques on tactile comfort of cotton fabric

    The effect of different mercerization techniques on tactile comfort properties of woven cotton fabric has been studied.Desized, scoured and bleached cotton fabrics are subjected to four different mercerization treatments at two levels oftemperature (20C and 65C) under two different conditions (tension and slack). Non-mercerized fabric is served as control.Results show that mercerization treatments improve the tensile strength of cotton fabrics owing to reduced fibre crystallinityafter mercerization. Highest increase in tensile strength is observed in case of hot mercerization in slack condition. Increasein low-stress mechanical properties, such as tensile energy, bending rigidity and shear rigidity values, indicates higherstiffness/toughness of mercerized fabrics. This is further reflected in their high Koshi (stiffness/firmness), low Sofutosa(softness) and medium Fukurami (fullness) values. However, mercerization causes significant decrease in frictionalcoefficient and surface roughness, and results in improved total hand value (THV). Total hand values range from 3 to 3.61;with highest being presented by fabric mercerized under hot and slack conditions. High hand value indicates fair suitabilityof this fabric in wear comfort

    Design of High-Speed Hybrid Carry Select Adders using VHDL

    No full text
    Carry select adder (CSA) is a square-root time high-speed adder. CSA is one of the fastest adders used in many data processing systems to perform fast arithmetic operations. In this project we propose to design hybrid carry select adders with a focus on high speed. CSA is a compromise between the longer delay Ripple carry adder (RCA) and the shorter delay Carry look-ahead adder (CLA). Conventionally carry select adders are realize using the full adders and 2:1 multiplexers. On the other hand hybrid carry select adders involve a combination of carry select and carry look-ahead adders.In this work, we propose to design hybrid carry select adders involving carry select and carry look-ahead adders with and without ripple carry adder (RCA) using very high speed integrated circuits hardware description language (VHDL)
