The release of fragmented fibers (FFs), including microplastics from textiles, during their service life is considered an established source of environmental pollution. The yarn structure is identified to affect the amount and length distribution profile of shed FFs from textiles. In the present work, the impact of yarn structures spun from 100% polyester staple fibers, using commercially relevant spun yarn technologies in the textile industry, on the release of FFs from textiles is studied. The bespoke woven fabric samples produced from three types of spun yarns, which include ring, airjet (air vortex) and rotor yarns, were subjected to an accelerated washing process, for up to five washes, to quantify shed FFs and their length distribution profile. The morphological shapes of FF ends associated with the nature of fiber damage were also investigated. The results demonstrated that airjet and rotor yarn structures had released 28% and 33% less mass of FFs, respectively, as compared to the ring yarn structure during the whole washing process. The length distribution profile identified that the ring yarn structure shed longer length FFs as compared to both airjet and rotor ones. The damaged ends highlight the importance of textile manufacturing processes on the generation of FFs. The results of this study give a better understanding of the yarn structural effect of commercially relevant technologies on shedding of FFs, which are released as a pollutant to the environment.

Investigation of ring, airjet and rotor spun yarn structures on the fragmented fibers (microplastics) released from polyester textiles during laundering

“…The fibers undergo fiber-to-fiber and fiber-to-metal friction during textile manufacturing, leading to fiber fatigue or fracture. 44 The higher release of FFs during the first cycle can be associated with the accumulated effect of abrasion and fiber damage during textile manufacturing. For the specimen (Figure 4), this release of FF mass decreases gradually up to the third cycle, and generally there is steady-state behavior in the subsequent cycles for each textile sample.…”

Impact of conventional and modified ring-spun yarn structures on the generation and release of fragmented fibers (microfibers) during abrasive wear and laundering

The abrasive wear of textiles during ordinary use and laundering results in fiber damage, which leads to the generation and release of fragmented fibers (FFs). Ring-spun yarn has a dominant share of about 70% of global spun yarn production. The effect of conventional and modified ring yarn structures (compact, SIRO and SIRO-compact) on FF release from cotton textiles during repeated abrasion and laundering was studied. All prepared cotton yarns and textiles are industrially and commercially relevant. The FFs formed during each abrasion and washing cycle were collected from textiles and quantified. The yarn tensile properties and fabric frictional characteristics were employed to explain the release of FFs. For the first time, the morphology of collected FF ends was associated with the fiber damage nature (granulated and fibrillated) induced by different types of stresses and experimental exposure conditions. The results demonstrated that modified ring yarn structures released a significantly lower FF mass as compared to conventional ring yarn structures. The tensile strength was decreased, and breaking elongation increased after repeated abrasion and washing. The fabric surface properties were also affected by abrasion and laundering. The yarn structure choices impact the amount of released FFs, which are dispersed into the environment as a pollutant or a carrier of pollutants with potential hazards to the health of the environment and living organisms.

“…33 Fibers and yarns are subjected to fiber–fiber and fiber–metal friction during textile manufacturing. 37 It is estimated that a single fiber may undergo over 10 million contacts with metallic parts during yarn spinning. 38 The loading and unloading effect, as well as vibrating and oscillating forces during the circulation flow in the spinning process, are responsible for fiber damage in the form of fiber fragmentation and the creation of short fibers (fibers smaller than 12.7 mm in the context of textile processing).…”

“…The higher increase in the first wash compared to subsequent washes (second to fifth) in all fibers may be associated with the pre-existing fiber damage due to mechanical and chemical stresses that fibers undergo during yarn spinning, fabric manufacturing, and coloration processes, as reported in Cai et al 33 Fibers and yarns are subjected to fiber-fiber and fiber-metal friction during textile manufacturing. 37 It is estimated that a single fiber may undergo over 10 million contacts with metallic parts during yarn spinning. 38 The loading and unloading effect, as well as vibrating and oscillating forces during the circulation flow in the spinning process, are responsible for fiber damage in the form of fiber fragmentation and the creation of short fibers (fibers smaller than 12.7 mm in the context of textile processing).…”

Fragmented fiber pollution from common textile materials and structures during laundry

The fiber damage during manufacture, use, and service of textiles leads to fragmented fiber generation. All textiles (natural, regenerated, and synthetic polymer sources) release fiber fragments. Several textile structural parameters have been studied in association with fragmented fiber release; however, there is a paucity of work on the effect of different fiber types and yarn structures on fragmented fiber release. This study elucidates the impact of key fiber types and yarn structures (rudimentary elements of textiles) on fragmented fiber release during laundry. Five different bespoke textile samples from three primary yarn structures (flat filament, textured filament, and staple yarn) from the two most employed fibers (polyethylene terephthalate and cotton) were subjected to repeated simulated washing processes to quantify shed fragmented fiber and length distribution of the collected fragmented fiber. The results show that yarn structure impacts the quantity of fragmented fiber shed and the length distribution profile. The release of fragmented fiber decreases during repeated washing of fabrics from staple and textured filament yarns, except for fabrics from flat filament yarns. The mean fragmented fiber length for all samples increases on repeated laundering. The quantity of fragmented fiber shed per gram of textile, and the length distribution profile of fragmented fiber from the woven fabrics made of the five types of yarns after the first and fifth washing cycles were estimated.
