A study on the functional properties of silk and polyester / lyocell mixed fabric

ABSTRACT Silk is one of the valuable fibers in textile industry. It is used for delicate applications in many areas such as sarees, suitings, curtains and luxurious interiors. To diversify the properties and usages silk is mixed with polyester and lyocell. The fabric is dyed with natural dyes (kum kum, indigo, barberry) as well as synthetic dyes (reactive dye (H), reactive dye (M) and sulphur dye). This mixed fabric is compared with 100% silk for some of the basic properties like absorbency, water retention, wicking, water vapour permeability, air permeability, K/S values, colour fastness and antimicrobial property. The silk mixed fabric gives the appreciable results with the 100% silk fabric

ORIENTAL JOURNAL OF CHEMISTRY A Study on Modal Fabric using Formic Acid Treatment for K/S, SEM and Fourier Transform Infrared Spectroscopy

AbSTRACT Modal is a second generation regenerated cellulosic fiber obtained from wood pulp, particularly from the beech tree wood. Modal was at first introduced by Lenzing AG Company of Austria. Modal is very soft, shiny in nature and silk feel than mercerized cotton with the ability to absorb up to 50% more water than cotton. In this study, modal fabrics (woven and knitted) are selected and conventionally pretreated and subjected with 98% formic acid in different concentrations. The formic acid treated modal fabrics were then undergone for different testings, such as, physical properties, wicking, K/S values, fastness properties, SEM studies and FTIR analysis. These treatments on modal fabrics were correspondingly compared with those of cotton for its effectiveness

Study on different reducing agents for effective vat dyeing on cotton fabric

349-352Effect of treatment with zinc (2.0% owm), ferrous sulphate (2.0% owm), zinc + hydrose (1.0% + 1.0% owm) and ferrous sulphate + hydrose (1.0% + 1.0% owm) reducing agents on dyeing properties of cotton fabric dyed with vat dye has been studied and the results are compared with those of the treatment with conventional hydrose (2.0% owm) in terms of reduction potential, depth of shade, and SEM analysis. The appreciable results are observed for the combination ferrous sulphate + hydrose as reducing agent, showing 99.17% colour strength with uniform dyeing and good reduction potential

Not AvailableAloevera, chitosan, and curcumin were applied in alone and in combination with each others on cotton, wool and rabbit hair by exhaustion method for the assessment of their antimicrobial activity. The antimicrobial activity of these natural ingredients was better in peroxide treated cotton, formic acid treated wool/rabbit hair fibrous substrates than their corresponding intact ones. Aloevera shown better antimicrobial activity than chitosan and curcumin when applied alone and its antimicrobial activity was enhanced by addition of both chitosan and curcumin. The application of aloevera+chitosan+curcumin combination on peroxide treated cotton and formic acid treated wool/rabbit hair fibrous substrate was fast up to twenty five washing cycles.Not Availabl

Surface modification of polyester fabric using polyvinyl alcohol in alkaline medium

287-291Chemisorption of polyvinyl alcohol (PVA) onto polyester fabric in alkaline medium has been conducted. The treated fabric is characterized by scanning electron microscope, ATR-FTIR spectroscopy, contact angle, differential scanning calorimetry and dyeability. The PVA treated polyester fabric shows improved hydrophilic character over intact and sodium hydroxide treated PET fabrics

Study on the improvement of hydrophilic character on polyvinylalcohol treated polyester fabric

Polyester fabric was treated with polyvinyl alcohol in alkaline medium. The moisture regain, water retention and wettability of the PVA treated polyester fabric were tested. The PVA treated PET fabric was dyed with disperse dye. The presence of PVA in the treated PET fabric was assessed by spot test. The treated fabric was also characterized by scanning electron microscope, FTIR and differential scanning calorimetry. The PVA treated polyester fabric showed improved hydrophilic character over intact and sodium hydroxide treated PET fabrics

Study on polyester fabric using polyvinyl alcohol in alkaline medium to enhance the hydrophilic character

Polyester (PET) fabric was treated with polyvinyl alcohol (PVA) in alkaline medium. The moisture regain, water retention and wickability of the PVA treated polyester fabric were tested. The presence of PVA in the treated PET fabric was assessed by spot test. The treated fabric was also characterized by scanning electron microscope (SEM). The PVA treated polyester fabric showed improved hydrophilic character over intact and sodium hydroxide treated PET fabrics.</p

Not AvailableLiterature information on the application of protease enzyme pretreatment followed by finishing treatment on wool-blended textiles for improving their performance properties is still inadequate. Wool/cotton union fabric was pretreated with savinase and papain enzymes separately followed by finishing with nine different finishing combinations. Savinase pretreatment had an influencing effect on handle and smoothness properties while papain pretreatment had improved comfort and mechanical properties. Each finishing formulation gave specific performance property in addition to softness. It is concluded that savinase pretreatment followed by Sandosoft-SPG+Ceraperm-MW+Ceraperm-Aqua combination finishing could be used to impart both softening and comfort finish to the wool/cotton union fabric.Not Availabl
