Environmental concerns related to perfluoroctanoic acid (PFOA) led to a re-examination of the methods for imparting stain resistance and stain repellency to textiles. Non-PFOA fluoropolymer finishes have been formed on cotton knits by admicellar polymerization, a surface analogue of emulsion polymerization. Fabric samples were characterized by a drop test, contact angle measurements, SEM, eleme...
The present paper furnishes the mosquito repellency of microencapsulated textile finishes developed using two essential oils- eucalyptus (Eucalyptus globulus) and rosemary (Rosmarinus officinalis) for cotton fabric. were prepared taking 10 percent concentration each oil as effect application at this on physical properties fabric was less in permissible limits. applied through pad-dry-cure metho...
the concepts of similarity and dissimilarity have been the interest of many researchers. basically, in the studies the similarity between two objects or phenomena, has been discussed. in this thesis, we consider the case when the resemblance or similarity among three objects or phenomena of a set, 3-similarity in our terminology, is desired. later we will extend our definitions and propos...
| Three-dimensional (3-D) integration of systems by vertically stacking and interconnecting multiple materials, technologies, and functional components offers a wide range of benefits, including speed, bandwidth and density increase, power reduction, small form factor, packaging reduction, yield and reliability increase, flexible heterogeneous integration with multifunctionality, and overall co...
The characteristics of the floor surface profile are one factors that can be responsible for slip and fall accidents. To reduce incidence these accidents, it is essential to identify features necessary covering materials suitable slipping risk areas. objective present work was investigate correlations between resistance roughness ceramic tiles. commercial tiles, with a diversity finishes, were ...
For making informed security decisions during the design of industrial control systems (ICS), engineers need to process large amounts security-relevant information outside their area expertise. This problem moves presentation into focus: engineering must be presented decision-makers in a way that enables them decide upon measures build defensible system. Visual representations have potential ef...
Microorganisms are present everywhere in the environment and can be helpful for mankind number of ways. Their harmful effects on cloths prevented by using a simple antimicrobial finish fabrics. In this cross-sectional study, an eco-friendly finisher were extracted from leaves Azadirachata indica, Butea monosperma Litchi chinensis plants applied 100% polyester. The plant extracted, grinded, soak...
