The hazard analysis and management is vital in textile industry to avoid accidents and wasting resources caused by the failures in production systems. Risk analysis is also very significant to decrease possible hazards and to avoid possible damage in manpower & production systems. In this study, an approach based on Failure Mode and Effects Analysis (FMEA) and Fault Tree Analysis (FTA) is proposed to analyse the ring spinning yarn production process in a textile industry. First, the possible hazards in the production line, yarn production system, in an integrated company operating in the textile sector are analysed by FTA method. Then, FMEA is applied to ring spinning yarn production process in a textile industry to rank all possible risks corresponding to hazards in descending order with respect to both occupational health and safety. It is very important to remove all possible hazards in textile industry to decrease the number of risks related to occupational health and safety. Therefore, in total of 57 hazard root causes are determined in the yarn production department. Subsequently, the faults related to the hazard root causes are examined by FTA and then risk corresponding to these hazards are prioritized by FMEA. The results obtained from the proposed FTA-FMEA approach show that decision makers and engineers can easily decrease the number of hazards and risks with respect to both occupational health and safety in practice
Abstract The utilization of nano materials creates a huge impact on today’s scenario in development of various products. One such type of nano material developing concept is the usage of nano fillers for making composite product. This review briefs about the development of various nano fillers and its types followed by the fabrication of various composite combinations along with various nano fillers also discussed in detail. The addition of these nano fillers as a reinforcement or matrix for the composite making creates a significant impact in the mechanical properties of the composites. Special focus is given in such a way that the nano filler dispersion in which way enhances the mechanical properties. Better bonding between the matrix and reinforcement only improves the property how the nano fillers behave in that aspect also discussed in this review. The dispersion of nano fillers in various polymer matrix composites also presented in the review. Tensile, Flexural and Impact property of the composites decides its usage in various structural applications and this review presents briefly how these properties varying with respect to various nano fillers. Further the nano filler performance on the thermal properties as well as its impact in various sectors such as automobile, biomedical, sports, and aerospace applications etc., also presented in this review paper.
