Preparation and characterization of cotton fiber fragments from model textile waste via mechanical milling and enzyme degradation

Siyan Wang,
Jeannie Egan,
Sonja Salmon

Abstract: Rather than land lling or incineration, value exists in textile wastes that should be recovered. Cotton is a major component of apparel and other textile materials that could nd new value by extracting it from textile waste in the form of cotton ber fragments (CFFs). To explore this potential, CFF properties were analyzed and compared after producing them from model undyed and ber reactive dyed textile waste fabrics by mechanical milling or enzymatic degradation. Characterization methods included scanning elec… Show more

“…Interest in the development of more mild, environmentally friendly processing techniques has resulted in the use of enzymatic methods to mimic the natural processes of breaking down biomass such as wood pulp into useful cellulosics such as cellulose nanofibers, as reported in the work by Henriksson et al [26]. Enzyme-mediated processes have also been explored for the extraction of microcrystalline cellulose fragments from cotton-containing apparel materials to promote more circular methods of sourcing cellulose for industrial applications [27,28]. The specifics of a required extraction treatment (i.e., agents, concentration, time) are governed by the desired properties of the cellulose and, in the context of additive manufacturing applications, vary based upon the target printing methods and applications.…”

“…The majority of the remaining waste is either sent to landfills or incinerated. Value can be found in the recovery of textile wastes, as opposed to disposing of them in landfills or through incineration [Wang et al, 2023, Bågenholm-Ruuth et al, 2023. Notably, well-known global brands such as H&M, UNIQLO, and Zara have recently mandated the incorporation of 30% recycled fiber into their clothing products by 2025 to benefit from concessional duty advantages.…”
