Cotton textiles results discussion

Abstract The use of two environmentally friendly technologies, the plasma and laser approaches, in treating the surface of textiles is discussed in this chapter. The surface of fibrous materials can be functionalized and structured on the nano- and micro-scales, and the results of the treatment of natural and synthetic fibres such as wool, cotton, polypropylene, polyester and polyamide which have been treated by different plasmas and lasers are detailed and are found to be similar to morphological modification of a textile surface using the ripple/roll-structure technique. 

Dimethylol-5,5-dimethylhydantoin (DMDMH) and 3-methylol-2,2,5,5-tetramethylimidazolidinone (MTMIO) were mixed in different ratios in textile finishing systems for cellulose fabrics. The mixtures of 2,2,5,5-tetrame thylimidazolidinone (TMIO) and hydantoin rings on the grafted cellulose provided a combination of imide, amide and amine halamine stmctuies in different ratios after chlorination. These combinations improved both the power and stability of the biocidal properties of the treated cotton and polyester/cotton blend fabrics studied. Repeated laundering tests showed that even a small amount of added amine halamines could substantially reduce the loss of active chlorine and increase the power of the biocidal functions on the fabrics. The results were discussed. 12 refs. 

The LCA results of cradle-to-grave analysis from raw material extraction to discarded textiles revealed that the textiles made out of acryl and PET have the least impact on the environment, followed by elastane, nylon and cotton. Additionally, it was also found out from this study that the use phase has less relative impact than is suggested in the classical literature (van der Velden et al., 2014). There were many other conclusions, which will not be discussed here. 

Surface modification/treatment of textile materials by chemical finishing processes is not environmentally friendly, as a result of which an alternative technology, laser irradiation has been widely adopted. By using laser irradiation, the textile materials can be structurally modified and their surface can be functionalized and textured. Here, two different examples of textile materials are presented and discussed in terms of laser treatment cotton,...
