The present study aims at the development of eco-friendly antimicrobial finished Bamboo/Cotton fabrics from the herbal extracts. The herbal extracts of Syzygium aromaticum (clove) buds have been applied on to the fabrics by two methods: Direct application method and Microencapsulation Method. The antimicrobial efficacy and the wash durability are assessed using AATCC 147, AATCC 30 and EN ISO 20645 standards. Both the treatments showed good antibacterial property and the microencapsulation method showed good antifungal property too. The Direct application method showed wash durability only till 10 washes, whereas the microencapsulation method showed very good wash durability till 30 wash cycles.

The reactive dye produce a lot of effluent problems in terms of % AOX, BOD, COD, TDS etc. in spite of its capability of produce wide range of colours and varieties of gamut in hue. In addition the use of salt as electrolytes provides higher chances of eco-hazardous impact problems and end-users comfort related properties. The % dye fixation is being always a problem to reactive dyeing on cotton due to the higher degree of dye hydrolyzation inside the dye bath. In this current work we had tried to develop an unconventional reactive process in both like salt free acidic medium reactive dyeing and salt free alkaline dyeing on pure cotton fabric. Results of the current study shows that alkaline medium salt free reactive dyeing on cotton shows higher colour strength (K/S value), good mechanical properties-bending length modulus, flexural modulus, less generation of the % AOX etc. It also can be concluded that acidic medium salt free reactive dyeing is also better in terms of quality than the conventional reactive dyeing method in the industries.

Textile industry is one of the fastest growing sectors with a turnover of over $1 trillion globally. The boom in this industry is seen very recently unlike other industries. This industry marked its infancy some 20 decades ago when old worn out clothes were modified to be used for different purposes. Textile industry usually consists of fabrics and clothing that highlights the durability and recycling characteristics of the material. Several different types of materials are being merged to form new material that have better durability and resistivity against physical parameters like heat, cold and other features.

Poly (lactic acid) (PLA) is an aliphatic polyester and ecofriendly material of a natural origin with biodegradable properties. The monomer for PLA is lactic acid obtained from the fermentation of sugar and vegetables like corn and cassava. This study investigated the effect of heatsetting and wet processes on the tensile properties of treated and untreated Ingeo™ Poly (Lactic acid) PLA knitted fabrics. PLA samples of dimension 200 mm×200 mm were subjected to heatsetting at a temperature of 130°C and increasing times of 15s, 30s, 45s, 60s, 90s, 120s and 240s respectively using the Werner Mathis infra red heatsetting equipment and subsequently treated to wet processes including scouring, alkaline reduction clearing, dyeing and softening. Four tensile parameters were determined in warp and weft direction using the KES-FB system of fabric evaluation. These tensile parameters were tensile extension EM [%], linearity of load extension LT [-], tensile energy WT [g.cm/cm2] and tensile resilience RT [%]. Results indicated a remarkable change in tensile properties of PLA with increasing times of heat setting and wet processes.

Fragrance finishing of textile materials has been greatly expanded and used in recent years. The textiles are worn, body temperature is ideal for the growth of bacteria. The prevention of microbial attack on textile material has become increasingly important which susceptible to microbial infestation. Fragrance finishing of textiles is one of the processes which enhance the value of the product by adding various odours to it. This paper examines the effects of fragrance finished fabrics by comparing the herbal and conventional methods, the best result are tested by the performance of the fragrance and laundering properties of the treated fabrics were investigated.

Yarn prepared from two technologies i.e. Ring frame and compact spinning system analyzed on Uster Tensorapid, Uster Evenness Tester. It was observed that yarn prepared with compact spinning system gives less variation in end products. Study also reveals that there was significant difference between tensile properties of yarn which was produced from compact spinning and ring spinning. Yarn produced from two technologies pretreated with scouring and bleaching process and structural changes occurred in yarn were analyzed on Uster Tensorapid, Uster Evenness Tester. In the present investigation it was observed that yarn produces from both spinning technique shows, strength reduced and elongation improved in compact spun yarn and count C.V. also found reduced for both systems after scouring and bleaching process. It was noticed that, yarn produced from compact spinning gives less yarn hairiness because of reduction in spinning triangle and protruding fibers were goes into yarn body which gives very good impact on subsequent processes.
