摘要: 利用亲水和非亲水性聚氨酯(PU)树脂,经一定的工艺加工成聚氨酯转移涂层织物。测量与分析了织物孔径结构、接触角、透湿量以及耐静水压等参数。结果表明,采用非亲水性PU树脂的涂层织物,仅有微孔透湿,透湿率低,但防水性好;而亲水性PU涂层织物,既有以水蒸气和液态水形式通过“溶解—扩散—吸附”传递;又有通过微孔质扩散,故该类亲水性PU涂层织物具有很好的透湿性能,但防水性不足,达不到PU涂层织物透湿性与防水性和谐统一的要求。

Abstract: Coated fabrics were produced by transfer coating processes using water-borne and non-water-borne polyurethane resins. The size of formation porosity, contact angles,waterproof and permeability of fabrics coated by polyurethane were tested and studied.It showed that water-nonborne polyurethane coated fabrics have better waterproof but less permeability only by porosity free diffusing, while water-borne polyurethane coated fabrics have better permeability but low waterproof because of both porosity free diffusing and molecular transportation diffusing.They can be satisfied with waterproof and permeability in harmony.
