Description
本申请是申请日为2018年06月23日、申请号为201810609845.9、发明名称为《一种椰壳活性炭面料生产方法》的分案申请。
技术领域
本发明属于纺织领域，具体地说，涉及一种椰壳活性炭面料的制备方法。
背景技术
活性炭布是以粉状活性炭为吸附材料，采用高分子粘结材料将其载附在无纺基体之上制成，具有良好的吸附性能，厚度薄、透气性好。市场上的活性炭一般以竹炭为主，竹炭的活性能力不是太强，所以不容易和其它物质结合，一般不可能均匀的分散在其它物质里面，合成的布料柔软度、厚度等性能受到很大影响，增加其功效的方法多是添加剂，对人体有害无益，故而，针对活性炭布的应用，局限在防化服与口罩领域，不能作为贴身衣物普及。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种椰壳活性炭面料的制备方法，为解决上述技术问题，本发明采用技术方案的基本构思是:
一种椰壳活性炭面料的制备方法，包括以下步骤：
步骤S1，取椰壳活性炭磨成粉末，得到椰壳活性炭粉末，取固态胶水磨成粉末，得到胶粉；
步骤S2，将椰壳活性炭粉末与胶粉按比例混合，均匀撒在底层布料上后，加温至胶粉熔化并包裹椰壳活性炭粉末；
步骤S3，降温，待胶水与底层布料粘合在一起后，用面层布料与底层布料叠合以覆盖胶水，加温至胶水熔化并与两布料粘合；
步骤S4，降温后成卷，得到椰壳活性炭面料；
所述步骤S1中椰壳活性炭粉末的粒径为0.03mm～0.1mm，胶粉的粒径为0.1～1mm。
进一步地，所述步骤S2中椰壳活性炭粉末与胶粉的重量比为1:(10～20)。
进一步地，所述步骤S2中加温的温度为60～110℃，步骤S3中加温的温度为90～130℃。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
本发明利用椰壳活性炭与布料的有效合成，得到的成品布料，具有更好的吸附性，同时抗菌、抗异味、防潮湿，并且厚度更薄更柔和，适合制作贴身服饰和家纺，无添加剂，绿色健康，该方法还能保证布料的水洗性，椰壳活性炭不会随着水洗次数而流失，保证性能可靠稳定。
本发明应用的椰壳活性炭活性能力强，吸附能力强，通过胶水的融合粘接，布料具有了较好的吸附能力，而且由于椰壳活性炭的吸湿性，能够吸收皮肤汗液，保证布料具有一定的湿度，对于保持皮肤的湿润有益，由胶水融合，椰壳活性炭的不会吸水饱和，因而不会造成潮湿环境。此外，椰壳活性炭的碱性，能够有效抑制细菌的滋生、繁殖，起到抗菌杀菌的效果，同时，椰壳活性炭的抗红外能力、负离子功效，均能对人体健康起到一定作用，可谓是绿色健康养生布料。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
实施例
一种椰壳活性炭面料的制备方法，包括以下步骤：
步骤S1，取椰壳活性炭磨成粉末，得到椰壳活性炭粉末，取固态胶水磨成粉末，得到胶粉。椰壳活性炭一般为小块状，固体胶水选用布料热熔胶，可用研磨机研磨，研磨完后椰壳活性炭粉末的粒径控制在0.03mm～0.1mm内，胶粉的粒径控制在0.1～1mm内，避免过大的粒径突兀。
步骤S2，将椰壳活性炭粉末与胶粉按比例混合，椰壳活性炭粉末与胶粉的重量比控制在1:(10～20)，本例中为1:20，混合后均匀撒在底层布料上，再将其加温至胶粉熔化，根据胶水的熔点控制温度，一般控制在60～110℃，熔化后胶水会呈流动状，胶水会包裹椰壳活性炭粉末。
步骤S3，降温，待胶水凝固，会与底层布料粘合在一起，用面层布料与底层布料叠合，胶水位于面层布料与底层布料之间，再加温，至胶水熔化，此为二次加温，温度可稍微高点，控制在90～130℃，胶水熔化后会与两布料粘合，即胶水将面层布料与底层布料粘接在一起；
步骤S4，降温后，面层布料与底层布料完好的粘接，将其成卷，得到椰壳活性炭面料。
本发明无任何添加剂，绿色环保，得到的成品面料，可用于制作口罩、防护服、贴身衣饰、家纺用品等，具体功效：
1、去异味：本发明面料有很强的吸附能力，不但能吸附异味还会把一些有害的物质吸附掉，本发明面料制作的衣物、口罩可实现对有害物质的高效吸附。
2、吸湿防潮：本发明面料有很强的吸湿能力，这个特性很适合人体的需要，它会将皮肤表面多余的水分吸附掉，到它吸附至一定量的时候，会将多余的水分一半排放到空气中一半留在皮肤表面，排放掉水分后再迅速将皮肤表面的一半水分吸附掉。当皮肤表面的水分不够时，它会吸附空气中的水分，到它饱和时它会把水分排放到皮肤表面和空气中，这时因皮肤的需要会迅速把水分固定在皮肤表面，使其达到保湿能力，本发明面料制作的衣物可保持人体表皮水分的平衡，利于保护皮肤。
3、抗菌：本发明面料有干爽、和弱碱性环境特性，具有天然的抗菌环境，一般有害细菌是喜欢潮湿和酸性环境，在这样的环境下的繁殖速度非常快，而在干爽和弱碱性环境下是很难繁殖的。现在的人以食肉为主，和现在的生活环境，使得现在人的身体以酸性为主，再加上环境的影响很多人都有很重的湿气，这样的身体一旦碰到有害细菌会很快的繁殖，而本发明面料制作的衣物就可避免细菌的滋生，有效抑菌。
4、远红外：本发明面料具有一定的远红外能力，用本发明面料做成婴儿枕可以活化婴儿后脑勺的毛细血管，这样可以帮助婴儿对食物营养更好的吸收。做成内衣裤也可以帮助人体恢复一些生理功能。
5、负离子：本发明面料有释放负离子的功能，可以给人体减轻一天劳累带来的负担，会中和人一天因为活动产生的大量正电离子，人身体的电离子少了就会感觉轻松舒服，脑子会更清醒。
本发明利用椰壳活性炭与布料的有效合成，得到的成品布料，具有更好的吸附性，同时抗菌、抗异味、防潮湿，并且厚度更薄更柔和，适合制作贴身服饰和家纺，无添加剂，绿色健康，该方法还能保证布料的水洗性，椰壳活性炭不会随着水洗次数而流失，保证性能可靠稳定。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许改动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
