Soybean Protein Fibres (SPF) are man-made fibres manufactured from the proteins contained in soybeans. They are biodegradable fibres derived from renewable sources, friendly for people and the environment. Within the framework of the work presented, selected utility properties of fabrics containing SPFs were investigated. The scope of the investigation included determination of mechanical properties, drapeability, water-vapour permeability and liquid moisture transport. The investigations carried out allowed to evaluate the utility value of fabrics made with the use of SPFs and to compare the fabric 100% made of SPFs with ones with weft yarns other than from SPFs. The research showed that fabrics with SPFs are suitable for clothing products, which may be a very good alternative to the currently available clothing made from fabrics containing standard natural and chemical fibres.
Moisture transport in fabrics influences the thermal comfort of clothing due to drainage of sweat secreted by the human body. The moisture transport through textile materials takes place in two ways: water-vapor transport and liquid moisture transport. Both ways are equally important. In the present work, liquid moisture transport in cotton woven fabrics with different weft yarns was investigated. Measurement was done using the Moisture Management Tester MMT M290. The obtained results confirmed that the linear density of weft yarn significantly influenced the values of all parameters characterizing liquid moisture transport in the investigated fabrics. The best performance in liquid moisture transport was achieved by weft yarn of linear density 30 tex. For this fabric variant, the maximum wetted radius for both surfaces was the biggest: 25 mm for the inner and 26.6 mm for the outer surface of the fabric. This means that the fabric spread the liquid on the biggest area compared to the other variants being investigated to facilitate an evaporation of liquid sweat. The fabric variant with 30 tex weft yarn showed the highest spreading speed: 5.83 mm/s for both sides, and the shortest wetting time: 2.83 s for the inner and 3.00 s for the outer side of the fabric. The higher the linear density of weft yarn, the worse the ability of cotton woven fabrics to ensure liquid moisture transport.
Cotton is the most common raw material of natural origin applied in clothing manufacturing. Clothing currently available on the market is usually made of plain weave fabrics. As part of this study, 3 pairs of cotton woven fabrics with different weaves (plain, twill 2/2 S, transverse rep 1/1) and different linear density of weft yarn (60 tex and 100 tex) were tested. The scope of research included determination of parameters characterizing the ability of fabrics to transport moisture in liquid form. The investigation was carried out on the Moisture Management Tester M290. The investigations allowed assessing the moisture transport of individual fabrics as well as the influence of both weave and linear density of weft yarn on the parameters characterizing the liquid moisture transport in the fabrics.
