Aesthetic Finishes for Home Textile Materials

Abstract: Fragrance finishing of textile materials has been greatly expanded and used in recent years. Fragrance finishing can be done effectively using exhaust method than any other methods. If the fabric is treated with fragrance agents which exhibits higher durability of functionality is estimated. Fragrance finishing can be done by means of lavender aroma with non-ionic binder. This paper examines the effects of fragrance finished aloe-vera and cotton fabrics. Finally both the fragranced finished fabrics were made into wall hangings and the ambiance of the room was evaluated by comparing various factors. In this investigation, factors such as fabric performance, durability of the fragrance and laundering properties of the treated fabrics were investigated. The fragrance finished fabrics can be used in home textile applications such as wall hangings, table covers, carpets and sofa covers.

Plant-based compounds for antimicrobial textiles

Abstract: Natural compounds from plants, including essential oils, resins, and biopolymers, possess various biological effects such as antibacterial, antimalarial, antifungal, and antioxidant activity as well as pleasant odor. Their medicinal properties are due to the presence of phenolics, terpenoids, and alkaloids, which are the lead constituents of many pharmacologically active compounds. These benefits can be applied on textiles to prepare various cosmetic or medical products to provide protection, therapeutic, or wellness properties. There is a relationship between the chemical structure of plant-based compounds and their biological function. This chapter provides a review of antimicrobial natural compounds and polymers with detailed discussions about their chemical structures, properties, and applications.

Eco-friendly Coloration and Functionalization of Textile Using Plant Extracts

Abstract: Chemical processing of textiles starting from preparatory processing to dyeing and finishing is important for its value addition in terms of fashion and function. However, these processes are water, energy, and chemical intensive and cause serious environment pollution. Recently, because of the increased global awareness of environmental pollution, demand for natural fiber-based textiles dyed with natural dye and finished with various bio-molecules is gaining academic, research and industrial importance. As a result, dyeing of textile has been carried out using various plant extracts because of to the presence of the inherent coloring compound. Some of these dyed textiles have also exhibited excellent UV protective functionality. Antimicrobial, mosquito repellent, well-being, and aroma functionalities have been incorporated into textiles using a number of plant extracts, such as neem, aloe vera, turmeric, arjuna, sandalwood, tulasi, jasmine, and eucalyptus oil. Cellulosic and ligno-cellulosic textile being highly flammable in nature, flame retardancy of such textiles has been improved using banana pseudostem sap (BPS) and spinach extract. The limiting oxygen index (LOI) of such treated fabrics is reported to increase to ≥30 as compared to the LOI value of <21 in untreated jute and cotton textiles, signifying the superior flame resistance property.

Handbook of Sustainable Apparel Production

Abstract: A hot-button societal issue, sustainability has become a frequently heard term in every industrial segment. Sustainability in apparel production is a vast topic and it has many facets. Handbook of Sustainable Apparel Production covers all aspects of sustainable apparel production including the raw materials employed, sustainable manufacturing proce

Finishes for protection against microbial, insect and UV radiation

Abstract: Fungi cause discolouration, coloured stains and fibre damage, while bacteria can produce fibre damage, unpleasant odours and a slick, slimy feel. A large number of compounds were previously used as antimicrobials, but many of them were banned as they are not eco-friendly. Free metals or their compounds are often used as antimicrobials, especially nanosilver, quaternary ammonium compounds (QACs), triclosan, biopolymers like chitosan and cyclodextrins. They can be applied by the exhaust method, padding or spraying; it can also be added before polymer extrusion. Several antimicrobial fibres are also produced by polymer grafting or blending antimicrobial agents. Insect-resistant finishes are required to protect wool and other animal fibres from attacks by the larvae of certain moths and beetles. Mosquito-repellent textiles protects people from the bite of mosquitoes and thereby assure safety from the infectious diseases they spread. Permethrin is widely used against a wide range of pests including mosquitoes, lice, ticks, fleas, mites and black flies. The damaging effects of solar UV are also well known, and the development of effective UV-protective finishes is of great importance to human health, society and environment.

Antimicrobial finishes for Textiles

Abstract: Infestations by micro-organism instigate cross disease by pathogens and odor develops in fabric have direct contact with the skin. Moreover, discoloration, tints and loss of functional characteristics of textiles are consequence of microbial damage. Antibacterial finished textile is an important area for medical and hygienic applications and there is enormous need of non-toxic and eco-friendly antimicrobial agents. The synthetic biocides finishes extensively reported were polyhexamethylenebiguanide (PHMB), quaternary ammonium compounds (QACs), metals (including metal oxides and salts), triclosan and n-halamines. Whereas, the natural based biocides (aromatic compounds, dyes, essential oil), chitosan and antimicrobial peptides (AMPs) were mainly considered among plant-based extracts.
