“…In addition, the sharp reduction of water absorption percentage for the coated fabrics might be because of the development of film as a hydrophobic layer going on the surface of the fabrics. No significant variation in (WAP) is noted by increasing irradiation dose of electrons beam [25].…”

“…The coating with UMAc oligomer would arrange as a film on the surface of cotton fabric; and thus enhances the roughness of and reduced the surface energy. The improvement of WCAs of cotton fabrics is due to the roughness and lower surface tension of the treat formulates [25]. Frequently, the low surface tension of the treated surface is the major role for repelling the aqueous liquefied [26].…”

“…Oils with higher surface tension, as castor oil (41.35 dyne/cm) or vegetable oil (26.8 dyne/cm) were repelled by the UMAc coating. This improvement in WCAs is owing to the surface homogeneity of coated cotton fabrics after being curative by electron beam radiation [25]. The lower surface tension of UMAc oligomer has a very pronounced beneficial effect on oil repellency.…”

“…The crease recovery is defined as the capability of the fabrics to resist and recover from the deformation produced through the loading on the surface. Crease recovery can be determined via the angle between the two pre-folded halves, which is termed the angle of crease recovery [25]. Figure 4 shows the effect of electron beam irradiation doses on the crease recovery angle of cotton fabrics, before and after they had been treated by coating with UMAc oligomer.…”

Cotton fabric was coated with trifunctional urethane methacrylate (UMAc) under the effect of electron beam irradiation to impart high hydrophobic and oleophobic characters to be suitable for furniture and tent usage. Acetone as a solvent in the presence of castor oil as a plasticizer was added to the formulation. Electron beam irradiation was proven to give the best homogenous fast curing of the formulation. The surface morphology that was examined by scanning electron microscopy (SEM) proved core coating and thickening of the fibers. The results indicated that the crease recovery and mechanical properties of coated fabrics were increased significantly, giving a high-performance fabric. The water absorption, water vapor permeability, and hydrophobicity of the treated fabrics toward water and aqueous liquids (tea and juice) were found to decrease. Oil repellency of the treated fabrics against different oils (clove, castor, and vegetable oils) was also studied. The contact angle for water-based and oil-based solutions was increased to reach 85° and 68° for tea and clove oil, respectively. Consequently, the results indicated that the hydrophobic and oleophobic properties of cotton fabrics were enhanced abruptly after the treatment process, accompanied by a slight increase in their thermal stability.

The leather tanning industry is one of the most polluting industries because it generates a gigantic amount of solid, liquid, and gaseous waste. Solid wastes are raw trimmings, fleshings, chrome shavings, buffing clouds of dust, and keratin wastes. Flesh wastes are generated from tanneries during leather processing, especially in sheep liming. These skin-flesh wastes from tanneries contain significant fat content, which is being wasted and dumped in open areas or at dumping sites. As a result, this flesh waste disposal has created a major environmental problem. This research aims to extract a sustainable functional substance that can be used for imparting aesthetic properties (polishing) to a leather product. In this research, a calculated amount of flesh waste was washed, de-limed, and cut into small pieces for solvent extraction of fat using the Soxhlet apparatus and hexane as solvent. Chemical analysis of the extracted fat showed a saponification value ranging from 189 to 192. These values indicate that extracted fat has a triglyceride, which can be used as a lubricant. However, when the extracted fat was applied to leather products like shoes, the surface showed an increase in their aesthetic properties (lustre, and gloss) giving excellent polishing results. The acid and saponification value, fat content, melting point, density, and viscosity of extracted fat showed stability making it a promising substance to impart functionality for leather products and usage as a polishing material. The extracted fat could replace synthetic, functional, and polishing materials overcoming the environmental challenges posed by the leather tanning process.
