“…Although the surface wax layer is hydrophobic, the bulk of kapok fiber is inherently made up of cellulose (64 %) which is hydrophilic [19]. However, as compared to the high water sorption by cotton [20], kapok fiber would absorb water to a much lesser degree, due to the presence of wax layer. Furthermore, the maximum amount of water sorbed was less than 1 % of the total amount of water (0.5 dm 3 ) which would qualify kapok fiber as a hydrophobic material.…”

This work was aimed at evaluating the sorption of dispersed oil by kapok fiber. The physicochemical characteristics of kapok fiber were investigated using BET, SEM, FTIR, XRD, contact angle and elemental analysis. The oil droplet size distribution at different temperatures was analysed using a Coulter counter, and its relationship with sorption was investigated. The effects of dosage, hydraulic retention time and temperature, on the sorption performance were studied. The result indicates that the sorption of dispersed oil by kapok fiber is spontaneous, endothermic and agreed with the pseudo-first-order reaction kinetics. The amount of oil that could be removed is about 28.5 %, while that of water is less than 1 % of the original amount (0.5 dm3). Kapok is a promising natural hydrophobic fiber for dispersed oil removal from oily wastewater.

“…Various studies have investigated the filtration properties of fabrics and have investigated factors such as breathability, hydrophobicity and/or electrostaticity. Fabrics also have a different weight per square meter (gram/m 2 ) and different moisture retention abilities, with cotton absorbing up to 500% of its weight and PA66 absorbing as little as 0.3% of its weight, depending on environmental conditions (29). These different properties may affect how fabrics trap and/or release aerosols or liquid droplets containing RNA viruses.…”

Infections with respiratory viruses can spread via liquid droplets and aerosols, and cause diseases such as influenza and COVID-19. Face masks and other personal protective equipment (PPE) can act as barriers that prevent the spread of respiratory droplets containing these viruses. However, influenza A viruses and coronaviruses are stable for hours on various materials, which makes frequent and correct disposal of these PPE important. Metal ions embedded into PPE may inactivate respiratory viruses, but confounding factors such as absorption make measuring and optimizing the inactivation characteristics difficult. Here we used polyamide 6.6 (PA66) fibers that had zinc ions embedded during the polymerisation process and systematically investigated if these fibers can absorb and inactivate pandemic SARS-CoV-2 and influenza A virus H1N1. We find that these viruses are readily absorbed by PA66 fabrics and inactivated by zinc ions embedded into this fabric. The inactivation rate (pfu.gram-1.min-1) exceeds the number of active virus particles expelled by a cough and supports a wide range of viral loads. Overall, these results provide new insight into the development of "pathogen-free" PPE and better protection against RNA virus spread.

“…The difference in the thickness of the fabric, which is corresponded to the yarn count, could affect the water volume absorbed by the fabric. It is reported that some processes of immersion, capillary sorption, adhesion, and spreading influence the wetting phenomenon of textile structures [19]. However, other study reported that yarn count affected the wetting rate of the fabric.…”

The batik production by home industries in Central Java, Indonesia, has been creating surface water pollution because of synthetic dyes, and triggers to its replacement by natural dyes. However, the use of natural dye could consumes more water, as the fabric should be immersed into the extract repetitively, which make up to the high of Blue Water Footprint. This study aims to examine the Blue Water Footprint (BWF) of batik production coloured by Myrobalan (Terminalia bellirica Roxb.) extract. An experiment was conducted in a large-scaled batik home industry in Jarum village, Klaten. White block-printed cotton fabrics, Myrobalan extract, and alum and copperas were used for the experiment, while water usage were calculated. The BWF of block-printed batik of both treatments were 156.48-158.70 L/pc or 68.52 L/m 2 of fabric, on average, which is mainly contributed by the dewaxing process. Implementing cleaner production, hence, is central to increase water use efficiency.
