Abstract

In spite of banning thin polyethylene bag, it has been used in Bangladesh by both retailer and consumer for its convenience and affordability and most utility comes from packaging retailed goods. There is a serious concern among consumers and environmentalists about the environmental impacts on plastic bags. Due to lack of proper plastic waste management our environment is becoming more and more polluted day by day. In the present study, an eco-friendly technique was adopted for reducing such type of pollution by reusing polyethylene shopping bag as polymer matrix in composite. Jute mill wastage which is commonly known as jute caddies (JC) reinforced waste polyethylene (WPE) based low cost randomly oriented discontinuous fibrous composite was fabricated using traditional hand layup method. Fourier Transform Infrared Spectroscopy (FT-IR) was used to investigate the chemical composition of both raw jute and jute caddies. Jute caddies content in the composite was varied from 20 to 45% where, 32% JC enriched composite showed the best performance in mechanical tests. Mechanical properties such as tensile and bending of composites were evaluated following several standard tests and methods. Jute caddies reinforced low density polyethylene (LDPE) based another type composite (JC/LDPE) was also fabricated to compare with JC/WPE. In order to increase the bonding strength between fiber and matrix, both types of composites were irradiated with gamma rays of dose varied from 2.5 to 12.5 kGy where, composites irradiated with 5 kGy dose delivered the best results. Water absorption tests of the composites according to the fiber content were done successfully for knowing the water resistance properties.

Abstract

In the present study ultrasonic velocity (U), density (ρ) and viscosity (η) have been measured at frequency 1 MHz in the binary mixtures of chloroquine phosphate with water in the concentration range (0.1 to 0.0125 %) at 303 K,308 K,313 K using multi frequency ultrasonic interferometer. The measured value of density, ultrasonic velocity, and viscosity have been used to estimate the acoustical parameters namely adiabatic compressibility (βa), relaxation time (τ), acoustic impedance (z), free length (Lf), free volume (Vf) and internal pressure (Πi), Wada’s constant (W) to investigate the nature and strength of molecular interaction in the binary mixture of chloroquine phosphate hydrochloride with water. The obtained result supports the complex formation, molecular association by intermolecular hydrogen bonding in the binary liquid mixtures.

Abstract

Scanning electron microscopy (SEM) and X- ray diffractometry (XRD) analyses has been used to investigate the structure of polyester fibre surface before and after treatment in some chlorinated solvents; perchloroethylene (PCE), trichloroethylene (TCE), 1,1- dichloroethylene (1,1-DCE) and tetrachloromethane (TCM) for different times in relaxed condition at room temperature. The results of the scanning electron micrographs did not show any observable internal damage in the fiber structure. On the surface however, several changes such as presence of micro voids, roughness and scissions of varying shapes, magnitudes and spacing density have been observed. The intensity of the diffracted peaks from the X- ray diffractographs of the treated fibre also showed a fall compared to the control one which may be accounted for in terms of the surface structural changes earlier on observed. The pretreatment of the polyester fibre with the chlorinated solvents was found to improve the dye uptake of all the treated fibres in the order of TCE > 1,1-DCE > PCE > TCM; this may be due to the large increase in the inter surface area swelling and greater segmental mobility of polymer molecules. TCE was found to be the best among the four solvents in terms of improvement in dye uptake. The improvement in the fastness properties (wash and light) of the pretreated fabrics was also observed. The chlorinated solvents used in this experiment caused structural differences on surface structures of the polyester fibres and these changes are very crucial to the behaviour of the polymer in fibre processing for other essential usage.
