    Himalayan nettle: a promising fibre on the rise
    (Wydawnictwo Politechniki Łódzkiej, 2022) Santiago, Ana; Pinheiro, Cláudia; Belino, Nuno
    The nettle is widely known as an "unloved" plant due to its unpleasant and even painful texture when incorrectly handled. However, it has very interesting therapeutic properties and stands out for its high sustainability, from cultivation, extraction, and fibre processing to the development of a long-lasting end-product with unique characteristics. With this paper we sought to demonstrate the growing relevance of the nettle fibre for the fashion industry, mainly their spinnability properties. For this purpose, a hand spun Himalayan nettle yarn (588,24 Tex) was bought and it were studied. A woven fabric with different wool/nettle compositions was produced and their main properties analysed. Our findings proved that due to the irregularity of the acquired yarn, it is not possible to obtain scientific statements concerning the properties of nettle yarn. However, this is a work in progress, which aims for more promising results.

    Multi-function woven fabric with carrier particles of PU-TiO2 coating filled in local pipes
    (Wydawnictwo Politechniki Łódzkiej, 2022) Zhou, Bin; Wang, Huiling
    For preventing nano material from coming into contact with skin to generate a toxic effect, Nano TiO2 is prepared by a sol-gel method. The appearance, the crystal form and particle size of TiO2 are researched through a scanning electron microscope (SEM) , an X-ray diffraction (XRD) and other instruments. PUTiO2 coating is prepared, the coating is uniformly coated to an outer layer of semen cassiae. Local pipes are formed on weft-wise front surface and back surface of woven fabric through a special process. By taking the local pipes with good sealing performance as carriers, semen cassiae is filled in the pipes. Two-ply silver-plated polyester/cotton (65/35) yarns are used as the raw material of warp and weft of the fabric, for providing special health care and protection functions for the fabric. An average particle size of the semen cassiae is 2.54 mm by testing, and all technological parameters are calculated to obtain a best number of semen cassiae particles added at the tubular structure. By testing, the results show that the ultraviolet protection factor (UPF), the transmittance(UVA), the maximum SE, the minimum SE, the heat preservation rate, bacteriostatic rate against escherichia coli and staphylococcus aureus of the designed fabric was 48.9, 2.92%, 51.3 (dBm),32.32 (dBm), 33.2%, 92.2%, 95.3%, respectively.

    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.
