Biotechnology for wool Wool plays an important role among the proteinaceous fibers. Although wool is considered all over the world a high-grade, valuable textile material, for many different purposes, a regularly constant decreasing in the market value of wool could be noticed. Improvement in selecting the raw wool by a good management for the acquisition [166] may change the today position of wool among other textile fibers. The today preference for synthetic fibers has to be reconsidered taking into account the decision to reduce the fossil consumption in favor of renewable raw materials [167]. The road from raw wool to the textile product contains a number of energy consuming operations, like: Carbonization→ Washing → Crabbing→ Dyeing → Finishing A solution for making these processes eco-friendly is to use biotechnology [168]. Wool carbonization consists in the elimination of the cellulosic residues present on the raw wool. It is usually performed with concentrate sulfuric acid delivering strong acidic wastewaters. The use of enzymes in this process represents a possibility to diminish pollution as well as the water and energy consumed. According literature, partial carbonization with cellulolytic enzymes has been realized [169]. Other studies involving Cellulases have …show more content…
Due to the complex structure of the wool fiber, which has overlapping scales at the external surface, the shrinking phenomenon appears. Modification in dimensions for wool products during use (washing especially), constitutes a major obstacle in wool applications in textiles, despite its qualities (e.g. comfort in cold as well as in hot weather, temperature insulating property, robustness, superior flame resistance, biodegradability, etc) [176, 19]. The shrinkage is often the reason for consumer complaints and reduced functionality of wool based materials. Thus, wool represents a minor segment of the total textile fibers globally produced
Fabric that came from Europe costed as much as the equivalent to the garment itself. It became less expensive to make your own fabric than to buy it. “Producing one’s own clothes . . . meant weavin...
Different chemistries and production methods of these fibers give them certain advantages. as viscose’s ability to combine with other fibers to create new fabrics easily) and disadvantages. such as nylon’s quickly weakening fibers or natural silk’s difficulty of production. other that make them more or less suitable for certain purposes. For this reason, when? considering silk and artificial silk, it is illogical to pick one fiber that is superior to the others.

The strengths of the book come from its’ accessibility. The book is easy to follow and provides readers with a great deal of information about the production of mass-manufactured clothing. As well as brings awareness to its’ many issues which we inadvertently take part in when we purchase such products. The book is well written and thoroughly researched but does have its’ share of weaknesses.
Enzymes, such as cellulases, which catalyse the breakdown of cellulose, have been isolated from several different organisms, including fungi. However, the purification of enzyme from these sources is expensive, on the order of $5.50 per gallon of ethanol produced. Genetic engineering or biotechnology has already played a key enabling role in the development of cellulosic biomass conversion technologies by dramatically reducing the cost of cellulase production from about $5.50 per gallon of ethanol to $0.10-15 per gallon of
While the price of cotton textiles decreased by 90%, the output had grown to cover the demand at affordable prices. Now, cotton will be gotten from Brazil, Egypt, southern United Sates and all this meant a...
Weaving is a common thread among cultures around the world. Weaving is a way of producing cloth or textile. Today we have machines that weave large-scale textiles at cheap prices. Production of cloth by hand is rarely engaged in today’s Westernized societies. Not many people are thinking about how the fibers are actually constructed to make their clothes. However, in other cultures across the world the tradition of weaving still exists. By comparing three cultures that continue weaving as a part of their tradition we can see similarities and the differences between them. The reasons that each culture still weaves vary, as do the methods and materials. The desired characteristics of the cloth also vary around the world as each culture values different aesthetics.

When it comes to wool one imagines idyllic surroundings and sheep who naturally shed their coats or need haircuts to keep cool during hot summer months, and one may believe sheep live this life until the final breath, but ones imagination is far from the truth. Even though wool is a multimillion dollar a year industry, due to the welfare of the animals that unwillingly have to participate this industry should be shut down. Lyn White, campaign director for Animals Australia states “Australian wool producers are striving to produce ultra-fine wool to supply the demand from elite fashion houses both in Australia and overseas. Each year, leading Italian fashion house Ermenegildo Zegna presents the prestigious ultra-fine wool industry trophy -- the Vellus Aureum Trophy -- awarded for the finest micron fleece. This year the trophy was awarded to The Wool Factory from Horsham, Victoria by Count Paulo Zegna and Australia's Gov...
Organically grown cotton plants have a tendency of being less productive, which, as a result, may make farmers find new agricultural land from forest. Various concerns are that most of clothing`s environmental impact emanates from the energy and water involved in washing and drying (Rissanen 34). Leather is a problem, especially for the animal realm. It is argued that the meat and leather dealings are intertwined in terms of economy.
First of all, the fibres can classified as natural or man-made fibres. Natural fibres are those obtained from the natural resources on the environment, whereas the man-made fibres could be synthetic or regenerated fibres. Synthetic fibres are completely made from chemicals while regenerated fibres are those originally from natural resources unsuitable to be used as fibres directly, processed chemically to be changed into textile fibres. In this assignment, we will study on the general textile manufacturing processes as listed below. Then, it is hoped that the knowledge on general process could help us understand more on the industry as well to relate it with the environment.
The main problem which was needed to overcome was the selection of the fabric. Due to sustainable principle, I tried best to find the most sustainable fabrics; however, it was full of challenge. 100% silk organza, 100% silk taffeta and 100% Merino wool which were essential in my project were hard to discover in the fabric market in the UK. After consideration, I decided to order these expensive fabrics from China and finally sorted out the problem.
From 2005 the textile segment has been made up of 2 companies, transforming raw materials into fabrics, from spinning to finishing and ennobling. Handicraft product quality and technological research development characterize this business segment which works with internationally recognized names of the apparel and fashion industry.
