废革胶原纤维/涤纶纤维水刺材料的缠结结构及性能

Entanglement Structure and Property of Waste Leather Collagen Fiber/Polyester Fiber Spunlaced Materials

采用不同水刺压强对废革胶原纤维/涤纶纤维的纤网进行加固成形,研究最终水刺材料的缠结结构,并分析了材料结构与性能之间的关系.研究结果表明:废革胶原纤维/涤纶纤维水刺材料的缠结结构主要由3部分组成,其中涤纶纤维的相互缠结作用是强力的主要来源;随着水刺压强的增加,涤纶纤维在厚度方向上的穿插程度越高,胶原纤维的开纤程度越大,试样表面平整度下降,材料在性能上表现为纵横向断裂强力的增大,平均孔径先减小后增大,对Cu2+的总吸附量呈增大趋势.

The waste leather collagen fiber/ polyester fiber webs are formed with different spunlaced pressure. The entanglement structure of the spunlaced materials is researched. Then the relationship between the structure and properties of the materials is analyzed. The results show that the entanglement structure of waste leather collagen fiber / polyester fiber spunlaced materials is mainly composed of 3 parts, wherein the polyester fiber entanglement with each other is the main source of the material＇s strength; with increasing of spunlaced pressure, polyester fibers intersperse in the direction of thickness with a higher degree, the splitting of collagen fibers increases and the surface evenness declines, so the tensile strength of the materials increases, average pore diameter reduces firstly and then increases, and the adsorption of Cu2＋ increases gradually.
