“…The Hercosett resin treatment of the chlorinated wool fibers without or in a combination with silicone resin increases their luster. Although the chlorine-based treatments provide highly effective and durable shrink-resistance, they decrease the strength as the surface scales are totally removed/etched, causes yellowing and also reduces the inherent stain-resistance of wool fibers [40]. The wool fibers are coated with a synthetic resin which affects the natural feeling of wool.…”

“…The effect of BSTP coating of wool fabrics on stain resistance of wool fabrics was considerably less compared to the other polymers [such as poly(chlorohydroxypropyl-diethylene adipamide ammonium chloride) or Hercosett 125] used for the shrink resistance of wool fabrics. 4…”

The Bunte salt-terminated polyether (BSTP)-based treatment has been developed for the chlorine-free shrink-resist treatment of wool fibers and fabrics. However, the effect of BSTP treatment on the physicomechanical and chemical properties of wool fabrics has not been thoroughly investigated. In this work, wool fabrics were treated with a commercially available BSTP at various concentrations by the pad-dry-cure process. The effect of BSTP coatings on the dyeability, shrink resistance, mechanical properties, wettability, hydrophilicity, and yellowness of the treated wool fabrics was systematically evaluated. It was found that the shrinkage of the treated wool fabrics considerably decreased with an increase in the BSTP concentration. On the other hand, the tensile strength, elongation at break, and surface hydrophilicity highly increased with an increase in the BSTP concentration. The tensile strength of the treated fabric was better than the tensile strength shown by the blank-treated fabric even at the lowest investigated concentration of BSTP (60 g/L). The bending rigidity as well as the bending modulus of wool fabric also decreased with an increase in the applied concentration of BSTP. The treatment showed very little effect on the yellowness and whiteness indices of wool fabric. The stain resistance against C.I. Acid Red 40 of the treated wool fabrics increased with an increase in the applied concentrations of BSTP. However, against red wine, the stain resistance decreased at lower concentrations of BSTP but showed a little effect for the higher concentrations. The coating of wool fabrics with the BSTP not only reduced the shrinkage of the fabrics but also increased their hydrophilicity and also the stain resistance against acid dye-based stain but also negatively affected their dyeability and stain resistance against red wine, especially at lower BSTP concentrations.

“…Basically, the wool fiber is covered by one or two layers of the cuticle, and the cuticle is surrounded by a fatty acid layer of 18-methyleicosanoic acid (18-MEA). The layer of 18-MEA is covalently bonded to the epicuticle through thioester bonds, which are together attached with the scaly surface, causing a water-repellent surface and a barrier to chemical treatment [ 36 ]. As demonstrated in the previous research, the partial removal of the scale layer by oxidation can assist the chemical diffusion into the fiber interior [ 37 ].…”

The compound 2-phosphonobutane-1,2,4-tricarboxylic acid (PBTCA) is an eco-friendly water treatment agent possessing flame-retardant phosphorus element and multi-carboxylic acid groups in its molecular structure. In the present work, PBTCA is employed as a finishing agent to improve the flame retardancy of the wool fabrics by the pad-dry-cure technique. The treated wool (10.2% weight gain) by 100 g/L of PBTCA showed an increased flame retardancy with a limiting oxygen index value (LOI) of 44% with a minimum char length of 40 mm. Importantly, the treated wool can self-extinguish after 30 washing cycles. The PBTCA-treated wool exhibited better stability with obviously increased char residue of 39.7% and 28.7% at 600 °C, while only 25.9% and 13.2% were measured for the control wool in nitrogen and air atmosphere, respectively. In addition, the high thermal stability of the treated wool with astonishing char-forming ability is confirmed by the SEM images of the wool after the isothermal heating treatment at different temperatures. Finally, a two-stage flame-retarding mechanism of enhanced crosslinking and char formability of PBTCA-treated wool is proposed and analyzed by infrared spectroscopy (TG-FTIR) and thermal (DSC and TGA) results of the pyrolytic volatiles of the treated wool.
