Towards circular economy by valorization of waste upholstery textile fibers in fibrous wood-based composites production

Abstract

The aim of the research was to utilize textile waste by adding upholstery fabric fibers with different content (0, 5, 10, and 20% by weight referred to dry wood fibers) to high density fiberboards (HDF) and analyze selected physical and mechanical properties of the obtained boards. Tests of mechanical (modulus of elasticity in bending and bending strength, surface soundness, internal bond, screw withdrawal resistance) and physical (density profile, swelling in thickness after immersion in water, water absorption) properties were performed. The results show that the increasing content of textile fibers in HDF panels has the strongest negative influence on mechanical properties, especially internal bond, and screw withdrawal resistance. Modulus of elasticity and modulus of rupture also decreased, but still fulfilled the requirements of European standards. No significant influence of rising content of textile fibers on HDF thickness swelling and water absorption has been found. It can be concluded that, depending on further application of HDF, it is possible to utilize the recovered upholstery textile fibers as a reasonable addition to wood fibers when producing HDF panels. It is also a step toward carbon storage extension, which is fixed in textile fibers.

The Influence of the Content of Recycled Natural Leather Residue Particles on the Properties of High-Density Fiberboards

“…As the proportion of leather particle fibers increases, the density difference between the face and core layers of the boards decreases. This remark is fully in line with the research on the incorporation of textile fibers into HDF panels [12]. The density distribution changes in the HDF face layers zone when raw material of different bulk density is added have been confirmed by Sala et al [31].…”

“…There is no statistically significant diff between the average SWR values. The raising SWR with leather particle content in is opposite to the tests, where the upholstery textile fibers have been added to th structure [12]. A similar tendency of a slight increase of the tested value with the in ing amount of leather particle content has been found for internal bonding (Figu The pictures of the samples with leather particles after the IB test are presented in 6.…”

“…Some of the carbon-rich materials, including natural leather, can be thermally transformed into higher-value raw materials and products [11]. In another study [12], different content (0-20%) of the addition of fibers from upholstered fabric waste in HDF boards was used. The tests showed a slight decrease in the modulus of elasticity and the modulus of rupture with the increase in fiber content, but they were still within the limits given by the standard.…”
