“…Indeed previously it has been reported that the structure and formation of the solvent spun fibres is affected by the dissolution, spinning and regeneration conditions (Fink, Weigel, Purz & Ganster, 2001). Rheological parameters such as DP, viscosity and cellulose concentration are defined at the dissolution stage and have impact on chain orientation and fibres formation at subsequent stages (Chanzy, Paillet & Hagège, 1990;Fink, Weigel, Purz & Ganster, 2001;Kim, Shin, Cho, Kim & Chung, 1999).…”

This paper investigated the supramolecular properties and accessibility of fibres regenerated from cotton-based waste garments and compared to typical lyocell fibres.The supramolecular and accessibility properties of the cotton-based waste garments fibres regenerated from three sources (waste denim garments, easy care finished cotton fabrics and a blend of cotton-based waste garment with wood pulp) were analyzed and compared to the lyocell fibres. The Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) spectroscopy and Wide Angle X-ray Diffraction (WAXD) analyses indicated that the fibres from cotton waste garments had supramolecular properties similar to the typical lyocell fibres. The exception was spun from the cotton pulp reclaimed from easy care treated cotton fabrics and maybe related to increased amorphous cellulose content in its structure. The fibre's accessibility by reagents behaviour correlated well with the supramolecular properties. The results indicate that the waste garment purification process may affect the properties of the pulp and hence the supramolecular properties of the resultant fibres. Further research on the purification and regeneration of fibres from waste garments may lead to the use of cotton waste garments as an alternative feedstock source to the lyocell process.

“…The dissolution of cellulose in NMMO solution is achieved by constant mixing at increasing temperature and reduced pressure so as to dehydrate the tertiary mixture of NMMO, water and cellulose into cellulose-NMMO solution (Chanzy, 1982, Chanzy et al, 1990and Kim et al, 2005. The dehydrated cellulose/NMMO solution is formed in a spinneret, stretched in an air gap and then the cellulose fibre is precipitated in any polar liquid which is a non-solvent to the cellulose (Johnson, 1969 andFirgo et al, 1997).…”

The aim of this research was to investigate the recycling of cotton waste garments by fibre regeneration. Easy care finished cotton fabrics and indigo dyed waste denim garments were successfully purified, dissolved in a suitable solvent and spun into fibres. The physical properties of the resultant fibres were compared with standard lyocell fibres spun from wood pulp and the fibres regenerated from the cotton waste garments exhibited improved mechanical and molecular properties relative to the typical fibres regenerated from wood pulp. Furthermore the results have indicated that a suitable blend of wood pulp and pulp reclaimed form cotton based waste garments can produce fibres with properties that are intermediate to cotton and lyocell fibres. The results suggest an alternative approach to fibre resource management by converting cotton based waste garment through regeneration processing into second lifetime cellulosic fibre. The approach will contribute to the reduction of both economic and environmental impact of waste garments and better management of resources required for production of cotton and synthetic fibres.

“…NMMO emerged as the best of the amine oxides, and its commercial potential was demonstrated by American Enka (85,86). Others (87) have studied the cellulose-NMMO system in depth; one paper indicates that further strength increases can be obtained by adding ammonium chloride or calcium chloride to the dope (88).…”

Fibers manufactured from cellulose are either derivative or regenerated; historically, they are designated man‐made fibers and distinguished from fibers based on synthetic organic polymers. A derivative fiber is one formed when a chemical derivative of a natural polymer, for example, cellulose, is dissolved and extruded as a continuous filament, and the chemical nature of the derivative is retained after the fiber formation process. A regenerated fiber is one formed when a natural polymer, or its chemical derivative, is dissolved and extruded as a continuous filament, and the chemical nature of the natural polymer is either retained or regenerated after the fiber formation process. The difficulties of making solutions of natural cellulose from which fibers can be spun has led to most fabricated cellulosic fibers being regenerated from more readily soluble derivatives of cellulose. It is the technology of making these fibers that is the subject of this article. Textile fibers and filaments composed of regenerated cellulose are called rayons. In Europe, the fibers are now generally known as viscose or lyocell; the term viscose rayon is used whenever confusion between the fiber and the cellulose xanthate solution (also called viscose) is possible. In addition to the viscose process, the cuprammonium rayon and direct dissolution–or lyocell processes are also covered. Fiber properties and environmental and commercial issues are discussed.
