Description

一种可电加热的水性聚氨酯服装革及其制备方法
技术领域
本发明属于环保合成革领域，特别涉及一种可电加热的水性聚氨酯服装革及其制备方法。
背景技术
水性聚氨酯合成革应用于服装如今已十分普遍，市场上各种纹路、颜色的水性聚氨酯服装琳琅满目。由于服装革单薄的特点，做成服装后可以防风却不能保暖。单薄的服装革面料在冬季的寒冷天气，只能依靠夹层填充羽绒、聚酯纤维等方法来提高保暖性，但是这些方法会导致皮衣的造型臃肿不美观。
随着人们的消费观念的改变和审美要求越来越高，传统的工艺和产品已经无法满足消费者的需要，生产更加轻薄和保暖的服装是市场。目前市场上使用电加热的方法来解决这一问题，方式是将加热片固定在衣服的不同位置，通过干电池或移动电源来供电，温度控制器和开关来控制温度，以达到保温的效果，其缺点是加热片无法水洗，且形状尺寸无法裁剪，不能满足不同尺码、款式服装的需求。
发明内容
鉴于现有技术中水性聚氨酯合成革无法兼顾美观和保暖，且现有的加热片方式受限较大的缺点，本发明提供一种可电加热的水性聚氨酯服装革及其制备方法。
为了解决本发明的技术问题，所采取的技术方案为，一种可电加热的水性聚氨酯服装革的制备方法，包括如下步骤；
步骤一、制作合成革金属丝无纺布：
S11、纤维经过梳理、铺网后与金属导热丝层进行复合，再经过针刺、水刺机加固制得金属丝无纺布；
S12、配制阻燃填充树脂，加入含浸槽中待用；
S13、将步骤S1的金属丝无纺布浸润在含浸槽中，采用浸润与挤轧相结合的三浸三轧工艺后挤压去除多余浆料，在90-140℃下高温烘干，制得合成革金属丝无纺布；
步骤二、制作导电皮膜：在离型纸上涂布面层树脂，涂布量为80-150g/㎡，烘干得到面层树脂层；然后在面层树脂层上涂布发泡树脂，涂布量为200-600g/㎡，烘干得到发泡树脂层；在发泡树脂层上涂布导电底胶，涂布量为130-200g/㎡，形成导电底胶层，即制得导电皮膜；
步骤三、制作可电加热的水性聚氨酯服装革：将导电皮膜中导电底胶层所在的面与合成革金属丝无纺布进行贴合，去除离型纸，即制得可电加热的水性聚氨酯服装革；
其中，步骤一、步骤二不分先后顺序，步骤S11、S12不分先后顺序。
作为可电加热的水性聚氨酯服装革的制备方法进一步的改进：
优选的，所述纤维由以下重量份的原料经混合纺丝制得：50-100份的聚酰胺即PA、100-50份的聚乙烯对苯二甲酸脂即PET、0-10份的色母粒。
优选的，步骤S11中所述金属导热丝层由细度为50-100D的银丝或铜丝铺设而成。
优选的，步骤S11中所述金属丝无纺布的厚度为0.45-0.55mm。
优选的，步骤S12中所述阻燃填充树脂由以下重量份的原料组成：第一水性聚氨酯树脂100份、水50-200份、阻燃助剂10-50份、抗撕裂助剂1-5份、消泡剂0.3-2份、增稠剂0.5-5份、渗透剂2-10份、色浆1-30份，所述第一水性聚氨酯树脂为模量0.5-1.5mpa、伸长率600-1500％的脂肪族或芳香族水性聚氨酯树脂。
优选的，步骤二中所述面层树脂由以下重量份的原料组成：第二水性聚氨酯树脂100份、消泡剂0.1-0.5份、电气石粉或导电云母粉5-20份、润湿剂0.3-2份、增稠剂0.2-1份，所述第二水性聚氨酯树脂为模量1-3mpa的脂肪族或芳香族水性聚氨酯树脂。
优选的，步骤二中所述发泡树脂由以下重量份的原料组成：第三水性聚氨酯树脂100份、电气石粉或导电云母粉5-30份、发泡剂2-8份、增稠剂0.1-3份、色浆0.2-20份，所述第三水性聚氨酯树脂为模量0.5-2.0mpa、固含量40-65wt％的脂肪族或芳香族水性聚氨酯树脂。
优选的，步骤二中所述发泡树脂由以下重量份的原料组成：第三水性聚氨酯树脂100份、电气石粉或导电云母粉5-30份、发泡剂3-5份、增稠剂0.5-4份、色浆0-15份，所述第三水性聚氨酯树脂为模量0.5-2.0mpa、固含量40-65wt％的脂肪族或芳香族水性聚氨酯树脂。
优选的，步骤二中所述导电底胶由以下重量份的原料组成：第四水性聚氨酯树脂100份、电气石粉或导电云母粉6-20份、发泡剂3-4份、增稠剂0.3-0.8份，所述第四水性聚氨酯树脂为模量0.5-2.0mpa、固含量40-65wt％的脂肪族或芳香族水性聚氨酯树脂。
为解决本发明的技术问题，所采取的另一个技术方案为，一种由上述任意制备方法制得的可电加热的水性聚氨酯服装革。
本发明相比现有技术的有益效果在于：
本申请的金属丝无纺布由纤维经过铺网后与金属导热丝层进行复合制得，金属丝经过经纬纱铺网后均匀交织，交织点相互连通形成电传输网络，从而保证其任意裁剪之后均具有导电性；而金属丝无纺布含浸后，树脂固化后形成稳定结构。由于金属丝无纺布分布均匀、聚氨酯含浸后稳定性更好，该材料可任意弯折、水洗，裁剪、弯折、水洗后均不会导致其结构变化，完全满足客户对服装革的需求。
本发明制备方法步骤简单，利于工业化生产。采用本发明的制备方法制得的可电加热的水性聚氨酯服装革手感柔软、撕裂强度高、可触屏、保温性好，外接电源后可实现快速加热，安全可靠。
