ADSORPTION OF POLYVINYL ALCOHOL ON COTTON AND POLYESTER FIBERS

Surface Adsorption of Polyethylene Glycol and Polyvinyl Alcohol with Variable Molecular Weights on Zinc Oxide Nanoparticles

Short Cellulose Nanofibril/polyvinyl Alcohol Nanocomposite Fibers

Short cellulose nanofibrils (SCNF) were investigated as a reinforcement for polyvinyl alcohol (PVA) fibers. SCNF fibers were mechanically isolated from hard wood pulp after enzymatic pretreatment. Various levels of SCNF were added to PVA and gel-spun into continuous fibers. The molecular orientation of PVA was affected by a combination of wet drawing during gel spinning and post-hot-drawing at ...

Thermal Degradation Kinetic Data of Polyester, Cotton and Polyester-Cotton Blended Textile Material

Polyester (P), cotton (C) and Polyester-Cotton (PC) blended fabrics were treated with 350gpl of phosphorous containing flame retardant (FR) chemical. Oxidative thermal degradation of these fabrics before and after the treatment was studied using Thermogravimerty (TG) Differential Thermal Analysis (DTA). From TG output, quantitative mass loss of samples was calculated at definite temperature int...

The Interaction Effects of Montmorillonite and Glycerol on the Properties of Polyvinyl Alcohol-montmorillonite Films

Background and Objectives: Preparation and evaluation of nanocomposite films have become prevalent in recent years. Depending on the purpose of using the film, and considering the effects and interaction effects of nanomaterial and other modifiers on the film properties, the amounts of nanomaterials and modifiers should be optimized. The effects of montmorillonite (MMT), glycerol (GL), and thei...

EFFECT OF POLYVINYL ALCOHOL ON FLEXURAL STRENGTH AND SOME IMPORTANT PHYSICALPROPERTIES OFPORTLAND CEMENT PASTE

Abstract: This work was designed to investigate the simultaneous effect of both water-to-cement (W/C) and polymer-to-cement(P/C) ratios on flexural strength of type V Portland cement pastes containing polyvinyl alcohol. The obtained resultsconfirmed the strong effect of W/C-ratio on the effectiveness of the added polymer so that there exist optimum valuesfor both W/C and P/C-ratios. Pastes prep...
