As a kind of environment-friendly fiber, akund will create considerable interest in the apparel industry due to its fine luster, good moisture absorption, renewable and pollution free feature. This research is a comparative study of the physical properties of akund/cotton material and pure cotton material. Results show that the enhanced structure of akund/cotton compact yarn typically results in a lower hairiness and improved mechanical properties. However, the weaving of this kind akund/cotton blended yarn may meet a lot difficulty since its tenacity value hardly meet the minimum value calls for weaving. Another important guidance is that it necessary to reduce short fiber content that may be present in the yarn structure to adopt best evenness.

Hemp fiber has many excellent properties, but there are certain difficulties in spinning yarn because the fiber is hard and its cohesion is small. Cotton fiber is soft and its length, fineness is uniform therefore has excellent spin ability and can compensate for the shortage of hemp fiber. We developed the knitted fabrics that have moisture absorption and dry-fast properties using the hemp/cotton blended yarn and discussed weft knitting, dying as well as finishing processes. This shell fabric has special performance such as moisture absorption and air permeability, anti-mildew and antibacterial, anti-ultraviolet ray, antistatic, ecological health ect, which is the ideal sports and summer fabric.

Sulphonated jute fibres were blended with cotton at three different ratios, e g. 50:50, 60:40 and 70:30 for production of fine yarn and comparatively better ratio have been investigated. The plain woven fabric were prepared by sulphonated jute-cotton yarn. The set of warp and weft blended yarns was done on the one up and one down principle. The physico-mechanical properties of blended yarn and fabrics were studied and compared with that of jute yarn, cotton yarn and fabric. Key words: Sulphonated jute fibre, jute-cotton blend, mechanical properties, tensile strength and fabric construction. Bangladesh J. Sci. Ind. Res. 42(3), 281-286, 2007

The hygrothermal degradation of glass fiber/nylon composite was investigated after aged at 25°C, 50°C, 75°C and 100°C up to 1 month of total exposure in aqueous solution. The effects of moisture absorption and thermal aging on mechanical properties are compared as functions of temperature, fiber volume and concentration of sodium chloride. The amount of water absorption increases when the aging temperature is increased and the concentration of NaCl is lowered. In general, the mechanical properties decrease with amount of water absorption. The degradation rate of various mechanical properties is different depending on the temperature, fiber volume and the concentration of NaCl. The diffusion mechanisms of water in short-fiber reinforced nylon are discussed as functions of fiber volume, molding conditions and concentration of sodium chloride.

Epoxy resins are a widely used common polymer due to their excellent mechanical properties. On the other hand, cellulose nanofiber (CNF) is one of the new generation of fibers, and recent test results show that CNF reinforced polymers have high mechanical properties. It has also been reported that an extremely low CNF addition increases the mechanical properties of the matrix resin. In this study, we prepared extremely-low CNF (~1 wt.%) reinforced epoxy resin matrix (epoxy-CNF) composites, and tried to understand the strengthening mechanism of the epoxy-CNF composite through the three-point flexural test, finite element analysis (FEA), and discussion based on organic chemistry. The flexural modulus and strength were significantly increased by the extremely low CNF addition (less than 0.2 wt.%), although the theories for short-fiber-reinforced composites cannot explain the strengthening mechanism of the epoxy-CNF composite. Hence, we propose the possibility that CNF behaves as an auxiliary agent to enhance the structure of the epoxy molecule, and not as a reinforcing fiber in the epoxy resin matrix.

The influence of the pretreatment polyester short fiber on the mechanical process and the properties of the NR/ SBR compound was studied by using contrast method. The results showed that the maximum power and the unit energy consumption increased because of short fiber, and the temperature also enhanced. So the low rotate speed is better. When the composite were cured, it had much characteristic such as rapid vulcanization speed, short scorch time and vulcanization smooth period. But the mechanical properties were increased. In the end, the microscopic photo of composite with the scanning electronic micrograph was taken.

To produce a tough material for application demanding high impact resistance and low moisture absorption, melt blending of Nylon12 (Polyamide 12, PA12) and natural rubber (NR) was carried out in a brabender plasticorder at 210 °C with rotor speed of 70 rpm in the presence of polystyrene/maleated natural rubber (PS/MNR) blend as a compatibilizer. The effect of compatibilizer content (1, 3, 5, 7 and 10 phr) on phase morphology, thermal, and mechanical properties of [Nylon12/NR]/[PS/MNR] blends was investigated by using SEM, DSC, and Izod impact tester, respectively. The result revealed that PS/MNR blend improved the compatibility of Nylon12/NR blends efficiently due to the presence of amide linkage at the interfaces from the reaction between the reactive groups of MNR and the NH2 end groups of Nylon12 during mixing. A fine phase morphology (good dispersion and small dispersed phase size of NR domains in Nylon12 matrix) of [Nylon12/NR]/[PS/MNR] blends was observed at the optimum compatibilizer content of 7 phr, relating to the improvement of mechanical property. The impact energy of [Nylon12/NR]/[PS/MNR] blends was 503 J/m higher than that of neat Nylon12 (115 J/m) and Nylon12/NR binary blend (241 J/m) due to the toughening effect of rubber and proper morphology. The melting temperature of all blends did not change obviously from thermal analysis. However, the presence of rubber particle obstructed the crystallization of Nylon12 phase, leading to the decreasing of %crystallinity from 93% to around 70%.
