水包蓖麻油乳液被称为加脂剂，用于润滑鞣制的皮革纤维，以获得柔软性并提高强度性能。加脂剂通常通过化学改性获得。以纳米TiO 2为乳化剂，采用机械混合法制备蓖麻油加脂剂。采用Pickering乳液法制备了蓖麻油/纳米TiO 2复合加脂剂（CTF）。纳米TiO 2的存在导致了稳定的乳液。透射电镜结果表明，蓖麻油被纳米TiO 2包裹。最后，将CTF应用于山羊服装革加脂工艺中。与硫酸化蓖麻油加脂相比，CTF加脂革的物理机械性能得到了改善。与改性蓖麻油加脂剂相比，CTF易于生物降解。纳米TiO 2复合加脂剂的加入，减少了皮革耐光性所需的多种化学品。
Castor oil in water emulsions known as fatliquors is used for the lubrication of tanned leather fibers to get softness and also to improve the strength properties. Fatliquoring agents are usually obtained by chemical modification. In this research, fatliquoring agent based on castor oil was prepared using nano-TiO2as emulsifying agent by mechanical mixing. So castor oil/nano-TiO2composite fatliquoring agent (CTF) was obtained via Pickering emulsion method. The presence of nano-TiO2resulted in a stable emulsion. The results of transmission electron microscope showed that the castor oil was surrounded by nano-TiO2. Finally, CTF was applied in the leather fatliquoring process of goatskin garment. Physical and mechanical properties of leather fatliquored by CTF were improved compared with those of leather fatliquored by sulfated castor oil. CTF was easily biodegradable as compared to modified castor oil fatliquoring agent. Composite fatliquoring agent leads to reduction of many chemicals utilized to get the lightfastness of leather for adding nano-TiO2.
