Description

一种废旧纺织品再生淘金毯的制备方法
技术领域
本发明涉及高分子材料技术领域，尤其涉及一种废旧纺织品再生淘金毡的制备工艺。
背景技术
目前河沙淘金用针刺毯的制造工艺是以聚酯类化纤短纤为原料，通过开松、混合、梳理、铺网工序形成均匀纤网，再采用针刺固结、正面起绒形成坯布，再经过背面上胶，烘干定型成成品地毯。但普遍存在克重小，耐冲洗性能差，出金量低的缺陷。
发明内容
本发明的目的是提供一种废旧纺织品再生淘金毯的制备方法，以解决现有技术中的不足，它能够克服耐冲洗性能差、克重小的技术难题。
本发明提供了一种废旧纺织品再生淘金毯的制备方法，包括以下步骤：
（1）以丙纶短纤和涤纶短纤为原料进行开松、混合、梳理、铺网形成均匀纤网；
（2）对均匀纤网采用针刺固结，其中一面进行针刺起绒；
（3）针刺加固起绒后通过上胶装置，对均匀纤网未起绒的一面涂覆胶液，胶液由羧基丁苯胶、碳酸钙、增稠剂和水组成，均匀纤网在上胶装置中的行走速度为3.5~4m/min；
（4）将涂覆胶液的均匀纤网进行烘干。
优选的是，步骤（1）中所述的丙纶短纤的质量分数为90%~96%，所述的涤纶短纤的质量分数为4%~10%。
优选的是，步骤（3）中所述上胶装置包括依次连接的导辊、轧液辊、浸渍辊、刮刀装置、传动辊以及输出辊。
优选的是，步骤（3）中所述胶液中的羧基丁苯橡胶的质量百分数为9%~16%、碳酸钙的质量百分数分别为65%~76.5%、增稠剂质量百分数为2%~2.5%，余量为水。
与现有技术相比，本发明的有益效果为：以废旧化学短纤为原料，通过针刺背胶等工艺，克服了耐冲洗性能差、克重小的技术难题，制备了一款具有较高出金量的河沙用淘金毡，促进了废旧纺织品的回收利用。
附图说明
图1是本发明上胶装置的结构示意图。
附图标记说明：1-导辊，2-轧液辊，3-浸渍辊，4-刮刀装置，5-传动辊，6-输出辊。
具体实施方式
下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能解释为对本发明的限制。
本发明的实施例：一种废旧纺织品再生淘金毯的制备方法，包括以下步骤：
（1）以丙纶短纤和涤纶短纤为原料进行开松、混合、梳理、铺网形成均匀纤网；
（2）对均匀纤网采用针刺固结，其中一面进行针刺起绒；
（3）针刺加固起绒后通过上胶装置，对均匀纤网未起绒的一面涂覆胶液，胶液由羧基丁苯胶、碳酸钙、增稠剂和水组成，均匀纤网在上胶装置中的行走速度为3.5~4m/min；
（4）将涂覆胶液的均匀纤网进行烘干。
步骤（1）中所述的丙纶短纤的质量分数为90%~96%，所述的涤纶短纤的质量分数为4%~10%。
如图1所示，步骤（3）中所述上胶装置包括依次连接的导辊1、轧液辊2、浸渍辊3、刮刀装置4、传动辊5以及输出辊6。轧液辊2与浸渍辊3在输送坯布的过程中以相反方向转动，对浸渍过胶液的淘金毯坯布进行挤压，从而将淘金毯坯布中多余的胶液挤出，节约原料。
步骤（3）中所述胶液中的羧基丁苯橡胶的质量百分数为9%~16%、碳酸钙的质量百分数分别为65%~76.5%、增稠剂质量百分数为2%~2.5%，余量为水。羧基丁苯胶是用于纸板涂布行业所需的全系列胶乳，具有较高的的结膜强度和粘结力，抗水可印刷性与耐磨性强，稳定性、流动性俱佳，填充量大，成模性好，机械、化学与冻融稳定性优异，与颜料、填料相容性好，贮存稳定性均佳。增稠剂是一种流变助剂，不仅可以使涂料增稠，防止上胶过程中出现流挂现象，而且能赋予料液优异的机械性能和贮存稳定性。碳酸钙用于橡胶的填充料。
以上依据图式所示的实施例详细说明了本发明的构造、特征及作用效果，以上所述仅为本发明的较佳实施例，但本发明不以图面所示限定实施范围，凡是依照本发明的构想所作的改变，或修改为等同变化的等效实施例，仍未超出说明书与图示所涵盖的精神时，均应在本发明的保护范围内。
