摘要:

针对超细纤维合成革存在吸湿性及透水汽性差的问题,选用栲胶等填充材料及牛蹄油等柔软剂对超细纤维合成革基布进行亲水交联改性。探讨了交联剂种类、交联剂用量、改性时间、改性温度及体系pH 值对超细纤维合成革基布性能的影响。结果表明:与未处理基布相比,交联改性基布的吸湿性提高了35.66%,透水汽性提高了53.23%,基布的抗张强度得到提高,增重增厚十分明显,且改性不影响其柔软度。扫描电子显微镜、水接触角、比表面积、综合热分析及X 射线衍射分析结果表明:交联改性基布的纤维松散程度明显提高,基布润湿性增加,比表面积增大,纤维规整度发生变化,且交联改性后基布具有较好的热稳定性。

Abstract:

Aiming at the poor moisture absorption and water vapor permeability of microfiber synthetic leather, the filling material such as tannin extract and softening agent such as neats-foot oil were selected to the influences of modify microfiber synthetic leather base to improve the hydrophilic crosslinking properties. By experiment, some correlative factors such as the types and dosages of crosslinking agent, crosslinking time, crosslinking temperature and pH value on the properties of microfiber synthetic leather base were investigated. The result show that the moisture absorption of the base modified by crosslinking agent increased by 35.66%, the water vapor permeability increased by 53.23%, the mechanical properties are significantly improved, the thickening rate and weight gain rate of the base are very obvious, and the  modification does not affect its softness. The base before and after crosslinking were characterized by scanning electron microscopy, water contact angle, specific surface area, thermal analysis and x-ray diffraction analysis. The results indicated that the fiber loose degree increased significantly, the active group content and wettability of base increase, the specific surface area of the base increased and the fiber neat degree changes. Moreover, it increases the thermal stability of the bases.
