Seacell fibres are readily processed using an established (lyocell) technology that is environmentally friendly. The resulting fibres are not cytotoxic and do not irritate sensitive skin, but they are antibacterial and fungicidal. Moreover, the fibre structure facilitates the active exchange of nutrients (such as calcium, magnesium and vitamin E) with the wearer's skin. © 2013 International Newsletters Ltd.

The tendency of wool is to felt and shrink is mainly due to its scaly structure. The chlorine-Hercosett is the most widespread process used to modify the scales of wool fibres with the purpose of providing resistance to felting and shrinkage. There have been many attempts are made to replace this chlorine process with an environmental friendly enzymatic process that would similarly degrade the scales. However, although proteases are large molecules, their attack is not only limited to the scales; they penetrate inside the fibre causing unacceptable weight and strength loss. It is believed that, if the proteases are chemically modified in order to increase their molecular weight, then they will act just on the surface of the fibres, thus providing wool with anti-shrinking behaviour.

Nature is constantly providing various resources for making textile materials for variety of applications. Though many textile fibers in the nature are available in the fibrous form itself, nature also offers raw materials that can be modified and formed into a filament in a way similar to the melt and solution spinning of other textile fibres. Basalt fiber is a material made from extremely fine fibers of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to carbon fiber and fiberglass, having better physico-mechanical properties than fiberglass, but being significantly cheaper than carbon fiber. It is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to produce products such as camera tripods. Basalt fibre offers an alternative to carbon and glass in the filament winding of compressed natural gas cylinders. Basalt-based materials are environmentally friendly and non-hazardous.

NO OR LOW SALT DYEING: - IS IT POSSIBLE? Many one might have got surprised, but its possible. Almost all cotton dyes are anionic during dyeing, but due to the negative is Zeta-potential of cotton in water among other things, anionic dyes have medium to poor affinity for cotton. Auxiliaries such as electrolytes are required for efficient use of dyes and for dyeing textile with high color strength. Despite electrolyte concentrations of 10 gpl or more, excess dye remains in the effluent after dyeing. The dye left in the effluent, together with the high salt concentration, increases the cost of dyeing, the burden of effluent treatment, and environmental pollution as well. One solution to this problem is to improve the affinity of anionic dyes for cotton. This is mainly accomplished by introducing cationic groups onto cotton to add an ionic attraction between dye and fiber. Fibers treated with these cationic agents, or agents that can form cationic sites under dyeing conditions, show such a remarkable increase in affinity for anionic dyes that no salt is necessary to assist dye sorption. In most of these cationic agents, nitrogen supplies the cationic sites. The agents are fixed onto cotton by covalent bonds either between cotton or their own reactive groups or by a cross linking agent.

There are many types of creels. Modern creels have yarn tension devices with automatic control and centralised tension variation. These devices allow also processing a wide range of yarns on the same creeling plant.
