    Comparison of composites containing technical embroidery and woven fabric as reinforcement
    (Wydawnictwo Politechniki Łódzkiej, 2022) Poniecka, Agata; Barburski, Marcin; Angulo, David Ranz; Cuartero, Jesus
    The following research present a comparison of the strength values of composites containing two types of reinforcements: technical embroidery and woven fabric. Both types of reinforcements were made of flax roving with a linear mass of 400 tex. The technical embroidery was made on a computerized embroidery machine ZSK, type JCZA 0109-550. The use of technical embroidery technology is in line with the idea of sustainable development by minimizing waste generated in the production of composite reinforcements. Tensile strength and tensile elongation tests were carried out. As a result of the conducted research, it was proved that the composite containing the technical embroidery as the reinforcement showed higher tensile strength in the longitudinal direction, compared to the composite containing the fabric as the reinforcement. On the other hand, the composite containing fabric as a reinforcement showed a greater elongation.

    Sound wave absorption properties of multi-layers of different woven fabric structures
    (Wydawnictwo Politechniki Łódzkiej, 2022) Bethalihem, Samuel; Barburski, Marcin; Witczak, Ewa
    Nowadays, acoustic health is a priority issue in homes and offices. To address the problem, a variety of sound-absorbing materials are used, one of which is woven and nonwoven fabrics. This paper focused on the sound absorption analysis of two different woven fabric structures as an increasing layer and with base material nonwoven fabric. The fabrics' sound absorption properties were determined using an impedance tube across 80–5000 (Hz) frequencies. The result demonstrated that the absorption of sound energy through plain fabric decreases as the number of layers was increased. On the other hand, in the case of a sateen fabric structure, the absorption of sound energy increases with the number of layers. The absorption capabilities of sateen fabrics are particularly impressive in the high-frequency ranges. The double and triple layers of plain fabric, on the other hand, demonstrate high sound absorption results at frequencies below 1000 Hz in comparison to sateen fabric.
