Potential use of textile dust in the middle layer of three-layered particleboards as an eco-friendly solution

Abstract

Textile (cotton) dust, which is harmful to humans and the environment, is one of the largest wastes in the textile industry. The aim of this study was to investigate the potential use of this waste in high value-added materials. Physical and mechanical properties and formaldehyde emissions of the three-layered particleboards with textile (cotton) dust in the middle layer were investigated in this study. A phenol formaldehyde resin was used as the binder in particleboard production. Four different amounts of textile dust (10%, 20%, 30%, and 40%) based on the oven-dried weight of the wood were obtained from a commercial textile manufacturer as industrial waste. The density, thickness swelling, modulus of rupture, modulus of elasticity, internal bond, and formaldehyde emissions of the produced panels were determined. The physical and mechanical properties and formaldehyde emissions of the particleboards were negatively affected, which decreased with the addition of a high amount of textile powder. At low rates, the use of textile dust in the middle layer did not significantly decrease the particleboard properties. Textile dust can be a partial solution for the raw material demand of the wood-based panel industry.

Towards Circular Economy by Valorization of Waste Upholstery Textile Fibers in Fibrous Wood-Based Composites Production

“…The only statistically signi cant differences have been found between 0% and 20%, for both, MOR and MOE. The same dependency was shown in research, where for 10% textile dust content in the particleboard, the MOR and MOE were 13.0 N mm -2 and 1814 N mm -2 , respectively and for 20% textile dust content, the MOR and MOE values were 12.9 N mm -2 and 1755 N mm -2 , respectively (Nemli et al 2019). There is a noted decrease in the value of mechanical properties with an increase in the additive content.…”

“…When comes to state of the art, in one of the studies, a way to use the residue from the textile production process in the form of textile dust was to use it in the middle layer of three-layer particleboard. It was considered that its 20% by weight could be accepted as an alternative to wood materials in particleboard production, but it had no signi cant effect on mechanical properties: internal bond (IB), modulus of rupture (MOR), and modulus of elasticity when bending (MOE), while it had a negative effect on them at 30% by weight (Nemli et al 2019). In order to observe the changes in physical and mechanical properties by modifying with another brous material in the production of the boards, tests were performed in which these additives were included in different amounts An example is the preparation of hybrid composite panels from wood debris and coconut ber.…”

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

“…As for the MOE (Figure 4), the best result for MOR is shown by the sample with a 5% leather particle content (45.5 N mm −2 ). This slightly increasing tendency for MOR with the leather particles increase is the opposite of the results of Nemli et al from 2019 [10], where the mechanical properties of particleboards decreased with textile dust content increase. The lowest MOE value occurs for the lowest natural leather particle content-3416 N mm −2 for leather particle content of 1%.…”

“…Research has shown, among other things, non-linear improvement of the internal binder with increasing leather content for HDF (4.5 mm, 900 kg m −3 ) [9]. There have also been trials to successfully utilize the textile dust in a share of 20% in the core layer of particleboards [10]. Some of the carbon-rich materials, including natural leather, can be thermally transformed into higher-value raw materials and products [11].…”
