Industrial fibres

In the United States the new entrants included Du Pont (with help from CTA), Tubize, ChatiUon, American Enka, The Industrial Fibre Corp. (later The Industrial Rayon Corp.), American Glan2stoff (later North American Rayon), and American Bemberg. By 1941 the production had risen to 1,250,000 tons.

Regioselective dialkylation of naphthalene is another reaction of considerable interest as 2,6-dialkylnaphthalenes can be oxidised to naphthalene-2,6-dicarboxylic acid, which is used in the synthesis of the commercially valuable polymer, poly(ethylene naphthalenedicarboxylate) (PEN).22 PEN has properties that are generally superior to those of polyethylene terephthalate) (PET) and has become the polymer of choice for a variety of applications such as in films, industrial fibres, packaging, liquid crystalline polymers, coatings, inks and adhesives. However, the high cost of naphthalenedicarboxylic acid has been a major hindrance to widespread application.

The nylon market can be divided into two segments resin products and fibre products. The total consumption of nylon in Western Europe was 913,000 tons in 1993, of which 560,000 tons were fibre products divided among textiles, carpets, and industrial fibre [22]. The total annual nylon consumption, as well as that of other engineering plastics, is small compared to that of high-volume commodity thermoplastics for example, the consumption of LLDPE/LDPE for 1993 was 5,548,000 tons [22]. Engineering plastics therefore constitute a minor share of the total plastics waste. Nevertheless, for an environmentally responsible company it is necessary to develop a clear strategy for the recycling of products and to help their clients do the same.

Asahi Carry out chemical recycling of PET bottles and post-industrial fibre waste. A methanolysis process termed Ecosensor is used to produce DMTA and EG, and is claimed to provide high-purity products which are used in fibre applications ( bottle to fleece system). No intellectual property has been found directly assigned to this company, which suggests that the process may be licensed from another concern. The website is tvtvw.ashai-kasei.co.jp.

Supercoiled 4>X174 RFl plasmid DNA was used for a target of respirable industrial fibre-induced free radical injury. The results presented by Gil-MOUR et al. (1995) revealed that the insulation wool MMVF 21 has much less free radical activity than asbestos fibres, but does have a detectable harmful... 

In many applications of industrial fibres the creep and the stress relaxation play an important role. Users often want to know creep and stress relaxation rates to enable them to predict long-term behaviour of these fibres. However, since the processes underlying these relaxation phenomena are still not well understood, the prediction of long-term behaviour is rather precarious. 

Polyamide 6 can be produced both by batch or continuous polymerisation. Batch polymerisation is preferably used for changing polymer formulations with a wide range of molecular weight, mostly compounding grades. Continuous polymerisation reactors - VK columns (Vereinfacht Kontinuierlich) - have a lower range of product mix but higher productivity and are, i.e. used for the production of textile or industrial fibres. Continuous processes can be operated with one or two reactors in series. 

Polyamide 66 is manufactured by polymerisation of the nylon salt monomer in solution. Different grades of polymer can be produced, with characteristics which depend on the further processing required downstream (spiiming, compounding, etc.), and on the specific application of the end-product, within the product groups in which polyamide 66 is involved (textiles, carpets, industrial fibres, engineering resins, etc.).
