Cotton textiles methodology

We extended the methodology developed for molecular characterization of cotton fiber to analysis of other polysaccharides. In this report, we present the results obtained from MWDs determined by SEC for various complex carbohydrate samples dissolved in DMAC-LiCl. Applications include cotton fiber, corn and wheat starch flours, and avocado cell walls. Relationships are evaluated between the respective MWDs and cotton fiber development, variety, inheritance, textile processing, and strength starch extrusion conditions and stage of ripening in avocado. 

In this chapter, the EF methodology is described considering its suitability to appraise products and processes. The methodology is applied to two different case studies of textile products. Firstiy, a case study of the EF calculation of a textile manufacturing plant is shown. The example selected with this aim is a dressmaking factory process. In this plant, cotton and synthetic jackets are produced. This example is considered to visualize the influence of resources, energy, wastes, and emissions flows in the EF obtained. After that, the EF will be applied to evaluate four different... 

Before examining the approaches to recycling textiles, it is important to place this discussion in the context of the product life cycle. The methodology of LCA is one approach to quantitatively assess the environmental advantages of recycling fibre. An LCA typically considers the energy, water and chemical impacts of a product system from cradle (raw materials) through to production, distribution, use by the consumer and disposal. Formal LCA follows ISO 14040 and ISO 14044 standards. It requires determination of the functional unit of the product or raw material in question to be assessed, for example T kg of cotton fibre , or one viscose blouse . Importantly, LCA is conducted under defined system boundaries. For example, the LCA may be... 

In this paper, two preliminary stages of die project are presented. Firsdy, the characterization of ceramides fiom wool fibres has been made, their cqubifity of forming liposomes has also been explored, and their benefits when they are topically applied have been assessed. Secondly, the methodology to follow their future application on textiles has been initiated by the use of a reference conqiouiid, the ethylhexyl methoxyciimamate (OMC) due to suitable analytical determination by HPLC (6) or by spectrophotometer UV-VIS techniques. The microciqisules widi OMC have been prepared by the industry Lipotec and their application on cotton has bear made by foulard. 

An experimental procedure has been established to apply microcapsules of a sun filter into cotton fabric. Moreover, a quantifying methodology to determine the amount of OMC present in the textile processed has been developed using deionised water as extractor solvent.
