In recent years, nanomaterials have been widely used in sports equipment, and their application in sportswear has also attracted wide attention. This research mainly discusses the application of nanomaterial antibacterial technology in the design of antibacterial fabrics for sports apparel. The method of adding nano-TiO2 to the antibacterial textiles varies with the type of fiber or fabric, and the finishing method also changes accordingly. For chemical fibers, the method of blending spinning is mainly used. By adding nano-antibacterial particles in the spinning solution, the polymer is ejected from the spinneret to make antibacterial fibers. This processing method is characterized by good antibacterial durability. The preparation of antimite finishing agent is mainly the dispersion of nanopowder. The selection of the best dispersant is mainly determined by measuring the change of the volume sedimentation rate of TiO2 after 5 days under different dosage and pH value of each dispersant. Then, the particle size of nano-TiO2 and Ag in different dispersing conditions was tested by TEM, and finally, the best dispersing agent and dispersing process were determined. The optimum of nano-antimite and antibacterial finishing agent is as follows: the dispersing agent is TW-80, the amount of anhydrous ethanol in dispersing medium is 5 times that of powder, the amount of dispersing agent is 1.5 times that of powder, the pH value is 7, and the stirring time is not less than 30 min. In the preparation of nano-antimite and antibacterial finishing agent, nanomaterials were used. The weight of nano-TiO2 powder was 20 grams and that of Ag was 20 grams. The dispersion medium (absolute ethanol) was 100 mL of dispersant. The amount of TW-80 was 30 g, the amount of citric acid was 60 g, the emulsion was very stable, and there was only a small amount of precipitation after being static for 5 days. Considering the characteristics of silk knitted fabric, this experiment uses the exhaustion method in the finishing process to finish the silk knitted fabric. After 50 times of washing, the antibacterial rate of Staphylococcus aureus and Escherichia coli reached 95.13% and 87.44%, respectively. This study provides guidance for the application of nanomaterials in the antibacterial field of sports clothing.

“…Finishing. In this section, we followed the method of Inprasit et al [28]. Square hemp fabric samples (5 × 5 cm) were pretreated with 5% w/v standard soap at 100°C for 30 min and rinsed with deionized water.…”

“…However, the color change was not a result of fading, but of a change to brown rather than to yellow. Color stability was also evaluated from color staining, which is defined as excess pickup of dye by a substrate due to exposure to a contaminated medium or by direct contact with a dyed material [28][29][30][31]. Table 2 shows the degree of color staining on multifiber, cellulose acetate, cotton, nylon, polyester, acrylic, and wool.…”

In this study, the dyeing performance and antibacterial properties of pomegranate (Punica granatum) peel extracts were investigated, when applied to hemp fabric. A tannin-rich natural dye was extracted using water at 100°C. As the antibacterial agent was sensitive to temperature, it was extracted using Soxhlet apparatus with methanol at 55°C. The color strength (K/S) values were investigated and found to increase in line with the dye concentration, dyeing time, and temperature. Optimal dyeing of the hemp fabric was achieved when applying 6% w/v of extract at 80°C for 60 min. This produced a yellowish-brown appearance. The dyed fabrics were rated as good to excellent for color fastness against washing, water, sea water, and perspiration. The dyed fabrics were next finished with the antibacterial agent extracted from the peel and tested for activity against Staphylococcus aureus (Gram positive) and Klebsiella pneumoniae (Gram negative), using the AATCC-100 (percentage reduction) test. The fabric was demonstrated to be 99.99% effective against Staphylococcus aureus, and this was conserved across 20 wash cycles.

“…However, in recent years, there is an increasing interest in industrial hemp due to its environmentally friendly nature and various other advantages. One of these advantages of hemp plant is its antimicrobial effectiveness shown in various studies 18,19 . Hemp plant contains various chemical ingredients most of which has been shown to be antibacterial such as cannabinoids, nitrogen compounds, amino acids, proteins, glycoproteins, enzymes, sugars, hydrocarbons, alcohols, aldehydes, ketones, acids, esters, lactones, steroids, terpenes, flavonglycosides, vitamins, and pigments 20,21 .…”

Hospital-acquired infections especially those occur in intensive care units are an important source of mortality, morbidity, and cost. Plant materials have been an important source for antimicrobial agents for ages. To date, the antimicrobial activity of plant materials were generally tested using their extracts. There are only a few studies that deal with the antimicrobial activity of raw fibers and fabrics. This study aims to investigate the antimicrobial properties of raw hemp fibers and hemp fabrics that are in commercial production and compare them to the widely used cotton textiles. The antimicrobial activity was tested using the “disc diffusion method”. Hemp fiber and fabrics did not show any antimicrobial activity against 21 bacteria types. Contrary to the limited study in the literature, it was concluded that hemp fibers are not effective against nosocomial infections, but new studies with different fiber types are needed.
