Recycled wool

Recyeled wool is wool made from worn-out woollen garments and remnants of fabrie. To maintain its strength, we blend it with ordinary wool or other materials. Independent third party certification usually follows the Global Recyeling Standard (GRS). 

Synthetic fibers are the most popular fibers in the world it s estimated that synthetics account for about 65% of world production versus 35% for natural 

The majority of the world s PET production - about 60% - is used to make fibers for textiles about 30% is used to make bottles. It s estimated that it takes about 104 million barrels just to produce the virgin polyester used in fabrics. That means most polyester - 70 million barrels worth - is manufactured specifically to be made into fibers, NOT bottles, as many people think. Of the 30% of PET which is used to make bottles, only a tiny fraction is recycled into fibers. But the idea of using recycled bottles - diverting waste from landfills - and tinning it into fibers has caught the public s imagination. 

The reason recycled polyester (often written rPET) is considered a green option in textiles today is twofold, and the argument goes like this  

Energy needed to make the rPET is less than what was needed to make the virgin polyester in the first place, so we save energy.

The complex formed when a mordant dyeing is aftertreated in a dichromate solution is retained by the wool in preference to the unmetallised mordant dye, which may desorb to some extent during the treatment. The latter is rather unstable in an oxidising solution and quinonoid by-products are often formed. If the chromium complex of the dye is formed from the desorbed dye in solution, this will further complicate the composition of the aftertreatment liquor. Thus reuse of mordant dyeing and aftertreatment baths is not an option. Furthermore, 100% rejection of dichromate ions would be required if the permeate of a membrane process treating the effluent was to be recycled [42]. 

Direction of innovation (from the standpoint of the SubChem research group - 6b) If biopersistent basalt rock wools are replaced by biosolnble mineral fibres (in manufacture, processing, recycling), the internal exposure that causes cancer is reduced. This makes a significant contribution to occupational health and safety. 

The lanolin extracted from the wool is purified further for use in cosmetics, hand cream, boot-polish, and so on. Part of the permeate from the ultrafiltration is recycled to save fresh water. A particular advantage arises from the fact that the dissolved sweat components exhibit... 

Acrylic and modacrylic fibers have a wool-like appearance and feel, and excellent resistance to heat, ultraviolet radiation, and chemicals [Bajaj and Kumari, 1987]. These fibers have replaced wool in many applications, such as socks, pullovers, sweaters, and craft yams. Other applications include tenting, awning fabric, and sandbags for rivershore stabilization. The use of acrylic and modacrylic fibers in carpets is low since these materials do not hold up well to recycling through hot-humid conditions. This also prevents its use in the easy-care garment market.

The latter method has the advantage of recycling the natural or waste product. Significant examples are cotton modified with amines [3, 4], starch utilized in xanthate form [5, 6, 7], thiol type keratine gel prepared from the wool [8, 9,10], wool simply reduced [11] or modified with amine groups [12, 13, 14] and finally polysaccharides such as cellulose [15, 16, 17], glucose [18] or polyosides [19] modified with thiol or amine groups. 

Tertiary treatment processes are used only to eliminate materials which are not amenable to secondary treatment. A treatment method for wool scouring effluent has been developed, consisting of evaporation and incineration plant in combination with a biological plant [56]. The resulting condensates from the evaporation plant and the incineration residues are recycled so that the water, ammonia and scouring aids are returned to the production plant [57]. 

Similarly, an aqueous treatment for wool uses an isocyanate blocked with a bisulfite. In this case, the by-product bisulfite salt can be removed, and possibly recycled, by washing the fabric with water at the end. The dissociation temperature decreases in the following order alcohol > lactam > phenol > ketoxime > active methylene compound. e-Caprolactam is a typical lactam, ethyl acetoacetate a typical active methylene compound. This thermal reversibility has been used to prepare a polyurethane from 1,4-butanediol, 4,4 -diphenyldiiso-cyanate, and 4,4 -isopropylidenediphenol (bisphenol A) (2.30) that can be recycled just by remolding.76...

Wool is one of the best materials for carpets. It is hard-wearing and naturally flame-resistant. Although wool carpets tend to be more expensive, if properly cared for, they can last for 50 years or more. Use cork or wool for the underlay. Recycled underlays made from old car tires, fiber scraps, or compressed wood fibers are also available.
