“…Longer wool is preferred because it is easy to process and increases wool quality and production (Chisti et al, 2021). The cross-section area of wool fibres along wool length has an impact on the mechanical properties of those fibres; thus, wool fibres are subjected to tensile strength during wool processing, and this may affect the wool fibre cross-section area (Deng et al, 2007;Tandon, 2015). Longer wool results in stronger and smoother yarns, which are easier to handle during the spinning process.…”

Purpose South Africa’s wool industry plays an important role in the agricultural sector. The wool industry provides a valuable source of income for farmers who practice sustainable farming practices. However, wool farmers face numerous challenges, such as wool contamination, dirty wool and producing good-quality wool. Good-quality wool is determined by fibre diameter, clean yield, vegetable matter and staple length. This study aims to address these challenges. Design/methodology/approach A multiple regression analysis of price (R/kg) of White wool and Merino wool was applied to four variables fibre diameter: vegetable matter, clean yield and staple length. The analysis was based on the data for the 2009–2019 data from Cape Wools auctions. Findings Fibre diameter, clean yield and staple length, with exception of vegetable matter, made a statistically significant contribution to the determination of wool price after all other independent variables were controlled for (p < 0.05). A one-unit (micron) increase in fibre diameter resulted in a 0.404-unit decrease in wool price (R/kg). A one-unit (mm) increase in staple length resulted in a 0.022-unit increase in wool price (R/kg). There was no statistically significant association between vegetable matter and wool price. A one-unit increase in clean yield was associated with a 0.111-unit increase in wool price (R/kg). Research limitations/implications Since wool fleeces consist of the largest portion of wool shorn from sheep, it is important for wool farmers to focus on wool with low fibre diameter, high clean yield percentage, low percentage of vegetable matter content and good length of the wool. Practical implications Since wool fleeces consist of the largest portion of wool shorn from sheep, it is important for wool farmers to focus on wool with low fibre diameter, high clean yield percentage, low percentage of vegetable matter content and good length of the wool. Social implications In a developing country such as South Africa, this study is important for the following reason. It is understanding the wool characteristics that have the most significance influence on the determination of wool price for Merino wool and White wool might effectively help the wool farmers to adapt their production systems to improve the wool characteristics that determine wool price. Originality/value This study identified a need for a study to be conducted on all wool classes.

Textile fabrics were subjected to bio-pretreatment using high-activity laccase from Cerrena unicolor for comparison to standard alkaline scouring and organic absorber of ultraviolet (UV) radiation based on 1,3,5-triazine derivatives. The basic aim of the study was the development of textiles made of natural cellulose fibers (mainly flax or its blends with cotton) to provide barrier properties against UV radiation. Controlled application of enzymatic pretreatment of woven fabrics made of natural cellulose fibers allows for an efficient removal of impurities from these fibers, resulting in the improvement of sorptive properties and good penetration of dyeing agents, UV organic absorbers and other chemical modifiers, into the textile structure. In this way, products with UV-protection properties (ultraviolet protection factor >40) are obtained. These innovative barrier materials can be used for outdoor textiles that protect professional people from harmful effects of UV radiation.
