Moisture management property is an important aspect of any fabric meant for active wear fabric, which decides the comfort level of that fabric specially used as active wear garments. Regular physical activity is important to maintain consistency in human health. To achieve comfort and functional support during various activities such as walking, stretching, jogging etc., athletes and sports persons use active wear clothing. A fabric’s moisture management performance is also influenced by its air and water vapour permeability. The moisture management finish (MMF) and Antimicrobial finish (AMF) have been used to increase moisture absorbency; improves wetting, wicking action and antimicrobial performance. In this study, influence of MMF and AMF finishes on the moisture management property of different knitted active wear fabrics had been carried out. For the study two different knit fabrics of 100% Polyester and 100% Nylon with three different GSM levels (100, 130 and 160) has been selected. Further two varieties of commercially available functional fabric finishes have been also taken for the study. The result shows that in case of finished fabric at certain concentration level, as the fabric GSM increases the value of Accumulative one-way transport index (OWTI) %, water vapour permeability but same time drying rate increases. The result shows that in case of finished fabric at certain concentration level, as the fabric GSM increases the value of accumulative one-way transport index (OWTI) %, water vapour permeability decreases but same time drying rate increases. The knitted fabrics of 100% Polyester and 100% Nylon composition follow the similar trend. Further with the increase of fabric finish concentration level, OWTI %, and water vapour permeability (WVP) factor decreases while the drying rate increases.

This research work has mainly utilized agricultural waste material to make a good-quality composite sheet product of the profitable, pollution free, economical better for farmer and industries. In this study, from corn leaf fibre to reinforced epoxy composite product has been utilized with minimum 35 to maximum range 55% but according to earlier studies, pulp composite material was used in minimum 10 to maximum 27%. Natural fibre-based composites are under intensive study due to their light weight, eco-friendly nature and unique properties. Due to the continuous supply, easy of handling, safety and biodegradability, natural fibre is considered as better alternative in replacing many structural and non-structural components. Corn leaf fibre pulp can be new source of raw material to the industries and can be potential replacement for the expensive and non-renewable synthetic fibre. Corn leaf fibre as the filler material and epoxy as the matrix material were used by changing reinforcement weight fraction. Composites were prepared using hand lay-up techniques by maintaining constant fibre and matrix volume fraction. The sample of the composites thus fabricated was subjected to tensile, impact test for finding the effect of corn husk in different concentrations.

A sportswear fabric should have good stretch and recovery behaviour. This study facilitates an effective design and development of high-stretch sportswear using different knitted structure. Nine types of knitted fabrics were produced by varying the type of fibre and type of structure. An experiment work is done to study the fabric size, stretch and elastic recovery properties. The statistical analysis showed that type of fibre and type of knitted structure significantly influence the fabric stretch. Plain structure fabric showed higher stretch value than rib and interlock-knitted fabric. The high stitch density caused by reduce stretch value in the course- and wale-wise due to yarn floating rather than overlapping influenced the weight and thickness of knitted fabrics. The elastic recovery analysis indicated that the recovery value of plain-knitted structure with polyester-spandex blend is higher among studied fabrics. However, the recovery value decreased over time in comparison with stretch value.

Natural fiber has a more long history and these are very important in a wide range of applications in the textile sector. Basically, natural fibers have biopolymers and natural fibers are basically made from either plant or animal-sourced. The plant-based natural fibers are major constituent of cellulose content and animal-based natural fibers are comprised of proteins. Nowadays, more used around the world for the plant-based natural fibers to bioplastics, biocomposites materials in automotive industries. These make product are low cost, low density, low manufacturing energy consumption, and more biodegradable. The ever-growing environmental, ecological, and economical concerns lead to increased acceptance of natural fibers in every area of conventional synthetic material application. This is due to biodegradability, nontoxicity, combustibility, easy availability, nonabrasiveness, and good specific strength. The present study focuses on the functional application aspect of natural fibers, basically an identification of fiber, classification and application of fibers process parameters.

Healthcare and hygiene products are usually available over the counter and normally used for hygienic purposes to prevent infection and transmission of diseases, provide hygiene, and enhance care in the hospital ward and operating room. Nowadays it is a scientific research approach to big growing part in medical textiles, in healthcare and hygiene products. The day by day increase in demand of medical textile in different sectors like wipe to operating rooms are more advanced fabrics used with anti-fungal and anti-microbial applications. In this sector, new concepts of low-cost effective techniques are developing day by dayfor both patient and hospital staff to protect them from the effect of virus infection and other bacteria. This paper basically discusses the main role of hygiene and health care sectors application in medical textile.
