Nanotechnology is considered as one of the most promising technologies for the 21st century. Nanoscience along with nanotechnology encompasses the study and application of very small things and can be used across all the other science fields such as physics, chemistry, biology, materials science, and engineering. This technology overcomes the drawback of applying traditional methods to impart certain properties to textile materials. There is no hesitation that in the upcoming years, nanotechnology will break through into every vicinity of the textile industry. Application of nanotechnology in modern textile lies in areas where innovative principles will be combined into long-lasting, multifunctional textile structures without compromising the intrinsic textile properties including aesthetic, breathability, flexibility etc. The current condition of nanotechnological use in textiles arena is reviewed with an emphasis on improving various properties of textiles.

This research work was designed to explore the effect of different washing processes (enzyme wash, enzyme stone wash, enzyme stone wash with bleaching, heavy enzyme stone wash with bleaching) on various properties of stretch denim fabric. Different properties like tensile strength, tear strength, dimensional stability to washing, color fastness to washing, color fastness to water, color fastness to perspiration, color fastness to light, color fastness to rubbing, changes in fabric weight were investigated in context with different washing processes for stretch denim fabric. All tests were carried out according to the ISO (International Organization for Standardization). Enzyme washed fabric illustrated better performance regarding tear strength, tensile strength and dimensional stability; but showed moderate performance in different color fastness properties. But the color fastness to rubbing of heavy enzyme stone wash was excellent. No significant change was observed regarding the grade of color change and color staining for color fastness to wash, color fastness to perspiration and color fastness to light with respect to different types of washing processes like enzyme wash, enzyme stone wash, enzyme stone wash with bleaching and heavy enzyme stone wash with bleaching. The grade for dry rubbing and wet rubbing was comparatively better for enzyme wash rather than other washing processes. The GSM (gram per square meter) of stretch denim fabric also increased accordingly after different kinds of washing process rather than untreated stretch denim fabric. The dimensional stability of stretch denim fabric also altered after going through different washing process. The highest shrinkage was occurred in weft direction for heavy enzyme stone wash with bleaching.

Exploration on hydrogel fibres concerning about smart based application in the medical sector has stimulated great interests for the last couple of years due to its wide range of purposes that include actuators, artificial adhesives, transplantable tissue organs, cell scaffolds, cell therapeutics, wound healing, cartilage or bone regeneration. Nevertheless, recently hydrogel fibre based biomaterials have drawn great concentration for use in a wide variety of biomedical applications like the sustained release of drugs. This is due to the fact that, hydrogel fibers are biocompatible and their similarity about physical properties is in relation with natural tissue. This review article prescribes about the application of hydrogels with diversified prospects in tissue engineering, wound care dressings, soft tissue recovery and plastic surgery. As the products of hydrogels are composed with a group of polymeric materials, the hydrophilic network structure makes them competent for holding an immense quantity of water in their three-dimensional polymer network structure. A wide-ranging application of these products in modern industrial and environmental areas has already taken into account to be of prime importance. Inevitably, natural hydrogels right is now gradually replaced by synthetic types due to their larger amount of water absorption capacity, durability alongside with wide ranges of raw chemical resources.

Denim plays a vital role in the fashion industry. But today's fashion not only concern about its aesthetic property but also its comfortability. Objective: This study was aimed to explore the effect of different softeners on the comfort and thermal feeling properties of stretch denim fabric. Method/analysis: For the understanding of comfort, feeling, and thermal properties of stretch denim fabric in conjunction with enzyme wash and stone enzyme wash; different softeners like cationic, anionic, nonionic, micro silicone, macro silicone, and nano-silicone softeners were applied accordingly. Then water vapor permeability and comfort property tests were conducted to understand the effect of different softeners on comfort and thermal properties of stretch denim fabric. Findings: Comfort, feeling, and thermal properties of stretch denim fabric were affected by using different kinds of softeners. Enzyme and stone enzyme washed stretch denim fabric treated with silicone-based softeners illustrated better feeling performance regarding the smoothness, softness, and warmness sensation. For water vapor permeability analysis, nonionic softeners showed better performance for both cases of enzyme wash and stone enzyme wash rather than others. Furthermore, nonionic and anionic softeners displayed lower performance for thermal conductivity during compression and recovery than silicone-based and cationic softeners in context with both Enzyme wash along with stone enzyme wash treated stretch denim fabric. Novelty: This research is a novel work regarding the understanding of comfort and thermal feeling properties of stretch denim fabric by applying different softeners together with enzyme wash and stone enzyme wash.

This research work was intended to discover the effect of super white washing process temperature and OBA (optical brightening agent) concentration on various properties of stretch denim fabric. Different properties like tensile strength, tear strength, dimensional stability, pilling resistance, hand feel performance, color fastness to washing, color fastness to perspiration, color fastness to light were investigated. All experimental tests were carried out according to the ISO (International Organization for Standardization) standards. Stretch denim fabric treated with super white washing process demonstrated better results regarding tensile strength, tear strength and dimensional stability for 35°C temperature and 30g/L OBA concentration along with illustrated moderate to good ratings in different color fastness properties after gradual increase of processing OBA concentration and temperature; although no significant change was observed regarding the grade of color change and color staining for color fastness to wash, color fastness to perspiration and color fastness to light with respect to stretch denim fabric treated with super white washing. The grade for pilling resistance and hand feel performance was comparatively good after the elevation of processing temperature and OBA concentration. The GSM (gram per square meter) of stretch denim fabric also changed accordingly after increasing the OBA concentration and washing process temperature for super white washed stretch denim fabric. The dimensional stability of stretch denim fabric also altered after going through different OBA concentration and washing process temperature.
