Description
技术领域
本申请涉及服装的技术领域，更具体地说，它涉及一种抗菌家居服布料及其生产工艺及应用。
背景技术
家居服是指在在家中休息或操持家务等，穿着的一种服装。随着生活水平的不断提高，人们现在慢慢把目光聚焦在如何更好的享受生活，家居服体现的是讲究的生活态度。家居服最主要的特点是舒适，因而家居服的款式一般都是比较宽松、随意的。家居服有很多种，按照功能分，主要有睡衣、睡裤、睡裙、睡袍、晨衣、浴衣、家务服等种类。
目前用于制造家居服的面料主要有棉、麻或者两种混纺以及涤纶和丝织品。棉纤维吸湿力强，手感柔软，透气性能好；涤纶属于合成纤维，耐磨抗皱、不变形，易洗快干、吸湿性差、易起静电；丝织品吸湿性好，蛋白质产生的光泽感显得高贵，缺点是不能拧，怕暴晒，不易打理。
针对上述中的相关技术，发明人认为人体的皮肤是最大的呼吸器官，当皮肤与家居服接触时，皮肤上分泌的油脂、汗液会附着在家居服上，导致家居服上滋生细菌，严重时会引发人体产生过敏性皮炎或其它一些皮肤疾病。
发明内容
为了改善家居服的抗菌性能，本申请提供一种抗菌家居服布料及其生产工艺及应用。
第一方面，本申请提供一种抗菌家居服布料，采用如下的技术方案：
一种抗菌家居服布料，包括基层、面层以及设置在基层和面层之间的抗菌层，所述抗菌层通过抗菌液涂覆在所述基层上形成，所述抗菌液由包含以下重量份的原料制成：聚氨酯树脂20-25份、竹炭粉10-15份、聚醚胺5-10份、壳寡糖4-8份、有机蒙脱土3-6份、纳米二氧化钛3-5份、纳米银1-3份、分散剂2-3份以及成膜助剂1-2份。
通过采用上述技术方案，由于采用在基层上涂覆抗菌液形成抗菌层，抗菌液中的聚氨酯树脂的透气透湿性好，作为粘结剂粘结抗菌层和基层，提高抗菌层与基层之间的连接强度，从而提高布料的水洗性能，保证水洗后的布料依旧保持良好的抗菌效果。竹炭粉可以吸收水分中的H+,同时放出OH-,可以吸附和抑制细菌、病毒，从而达到良好的抑菌、杀菌的作用。竹炭粉还具有吸附人体异味、吸湿排汗的作用。壳寡糖分子中含有-NH2，-NH2吸引H+形成-NH3 +，-NH3 +与带负电荷的细菌菌落相互吸引并包裹在细菌表面，从而阻碍了细菌对营养物质的吸收；另外壳寡糖通过渗透作用进入细菌细胞内部，破坏胞内物质，通过自身所带电荷的作用使胞内蛋白发生变性，因此壳寡糖起到抑菌效果。聚醚胺分子中含有-NH2，一方面具有抑菌的作用，另一方面能够与基层纤维表面的基团形成氢键，提高抗菌层与基层之间的连接强度，从而提高布料的水洗性能。有机蒙脱土层间带负电，具有较高的阳离子交换能力，对细菌有较强的吸附固定作用。纳米银可使细菌的细胞膜通透性增加，银离子稳固吸附在细菌的细胞壁上，并通过库伦吸引力透过细胞壁，与细胞里的巯基发生反应，导致细菌细胞内的蛋白变性，细菌无法继续分裂，最终死亡。另外银离子能够进入纳米二氧化钛的晶格中，在二氧化钛的禁带中引入杂质能级，减小禁带宽度，使得二氧化钛的光谱响应范围由紫外区向可见光移动，纳米二氧化钛产生活泼的·OH和·O2-，将细菌分解成二氧化碳和水，纳米银和纳米二氧化钛的协同作用，提高了抗菌的效果。
优选的，所述抗菌液的制备方法为：1)将聚氨酯树脂和聚醚胺加入到反应容器中，在170-200℃下搅拌20-30min；2)待步骤1)体系的温度降至140-160℃向步骤1)中加入竹炭粉、壳寡糖、有机蒙脱土、纳米二氧化钛、分散剂继续搅拌30-60min，得到悬浮液；3)最后向步骤2)中加入纳米银、成膜助剂搅拌10-20min，得到抗菌液。
通过采用上述技术方案，聚氨酯树脂和聚醚胺熔融后，降低温度继续加入其它原料，目的是充分混合各原料，提高抗菌液的性能。
优选的，所述成膜助剂为聚乙二醇。
通过采用上述技术方案，聚乙二醇能够促进抗菌液的流动性，抗菌液涂覆在基层上形成抗菌层的过程中，聚乙二醇能提供足够的自由体积，使得抗菌液中的高分子链段扩撒、缠绕而融合成连续膜。
优选的，所述分散剂为CTAB。
通过采用上述技术方案，因为纳米二氧化钛、纳米银粒子的纳米尺寸效应，他们在抗菌液中不易分散，容易出现团聚现象，CTAB能够吸附在纳米二氧化钛和纳米银离子表面，在纳米二氧化钛和纳米银周围产生屏障，增加空间位阻斥力势能，避免纳米二氧化钛和纳米银团聚。
优选的，所述基层由棉纤维编织而成。
通过采用上述技术方案，棉纤维柔软且吸湿透气性好，作为基层接触人的皮肤，使人感到柔软而不僵硬，舒适度较好。
优选的，所述面层由聚酰胺纤维、棉纤维、锦纶混纺编织而成。
通过采用上述技术方案，聚酰胺纤维的耐磨性能优异，面层与其它衣物接触时，会由于行动等因素使得面料层与其它衣物之间发生摩擦，面层中混纺有聚酰胺纤维，既能保证面料的柔软舒适性，又能提高家居服布料的耐磨性能；棉纤维柔软且吸湿透气性好；锦纶弹性好，经过反复揉搓后，很快就可以恢复原形，不留下褶皱，不易变形，因此能给提高家居服布料的质感。
第二方面，本申请提供一种抗菌家居服布料的生产工艺，采用如下的技术方案：一种抗菌家居服布料的生产工艺，具体包括如下步骤：
S1、基层预处理：基层经过蒸纱定型后，将基层置于40-50℃的水中，搅拌洗涤20-30min，再用去离子水冲洗3-5次后，烘干备用；
S2、制备抗菌层：抗菌液涂覆在基层上，涂覆厚度为0.5-1mm，然后在轧车上以1-3kg/cm2的压力轧掉多余的抗菌液，并将涂覆有抗菌层的基层置于烘箱中干燥处理；
S3、将面层贴合在抗菌层上，经过加压定型，得到抗菌家居服布料。
通过采用上述技术方案，基层经过蒸纱定型后，可以有效避免回捻作用，使得基层表面更平整，再对基层进行洗涤，能够除去基层表面的各种杂质和污渍，当抗菌液涂覆在基层上形成抗菌层时，抗菌层各处厚度均一，不会出现褶皱，使得家居服布料各处的抗菌性能一致，因此不会造成局部不均的现象发生。采用本申请的生产工艺生产的抗菌家居服布料的抗菌性能优异，抗菌层与基层之间的结合强度高，经过多次洗涤后，依旧能够保持优异的抗菌效果。
优选的，所述步骤S1中蒸纱定型的温度为80～120℃，时间为40～60min。
通过采用上述技术方案，蒸纱定型温度设置在80～120℃，时间控制在40～60min，使得基层纤维大分子之间的连接得以松弛，然后在新的位置上重新组合，从而消除纤维疲劳和静电，稳定捻度，防止在后道工序中产生小辫子扭结现象。
优选的，所述步骤S3中加压定型的压力为10-15MPa,并保压1-2min，定型温度为100-120℃。
通过采用上述技术方案，加压定型能够提高面层、抗菌层以及基层之间的连接强度，从而提高家居服布料的质量，保证家居服布料的抗菌效果。
第三方面，本申请提供一种抗菌家居服布料在家居服上的应用。
通过采用上述技术方案，由于采用抗菌家居服布料制做家居服，死的家居服的抗菌效果好，且经过多次洗涤后，仍然能够保持良好的抗菌性能。
综上所述，本申请具有以下有益效果：
1、由于本申请采用采用在基层上涂覆抗菌液形成抗菌层，抗菌液中的聚氨酯树脂的透气透湿性好，作为粘结剂粘结抗菌层和基层，提高抗菌层与基层之间的连接强度，从而提高布料的水洗性能，保证水洗后的布料依旧保持良好的抗菌效果。竹炭粉可以吸收水分中的H+,同时放出OH-,可以吸附和抑制细菌、病毒，从而达到良好的抑菌、杀菌的作用。竹炭粉还具有吸附人体异味、吸湿排汗的作用。壳寡糖分子中含有-NH2，-NH2吸引H+形成-NH3 +，-NH3 +与带负电荷的细菌菌落相互吸引并包裹在细菌表面，从而阻碍了细菌对营养物质的吸收；另外壳寡糖通过渗透作用进入细菌细胞内部，破坏胞内物质，通过自身所带电荷的作用使胞内蛋白发生变性，因此壳寡糖起到抑菌效果。聚醚胺分子中含有-NH2，一方面具有抑菌的作用，另一方面能够与基层纤维表面的基团形成氢键，提高抗菌层与基层之间的连接强度，从而提高布料的水洗性能。有机蒙脱土层间带负电，具有较高的阳离子交换能力，对细菌有较强的吸附固定作用。纳米银可使细菌的细胞膜通透性增加，银离子稳固吸附在细菌的细胞壁上，并通过库伦吸引力透过细胞壁，与细胞里的巯基发生反应，导致细菌细胞内的蛋白变性，细菌无法继续分裂，最终死亡。另外银离子能够进入纳米二氧化钛的晶格中，在二氧化钛的禁带中引入杂质能级，减小禁带宽度，使得二氧化钛的光谱响应范围由紫外区向可见光移动，纳米二氧化钛产生活泼的·OH，·O2-，将细菌分解成二氧化碳和水，纳米银和纳米二氧化钛的协同作用，提高了抗菌的效果。
2、本申请中优选采用聚酰胺纤维、棉纤维、锦纶混纺编织成面层，聚酰胺纤维的耐磨性能优异，面层与其它衣物接触时，会由于行动等因素使得面料层与其它衣物之间发生摩擦，面层中混纺有聚酰胺纤维，既能保证面料的柔软舒适性，又能提高家居服布料的耐磨性能；棉纤维柔软且吸湿透气性好；锦纶弹性好，经过反复揉搓后，很快就可以恢复原形，不留下褶皱，不易变形，因此能给提高家居服布料的质感。
3、本申请抗菌家居服面料的生产工艺，通过基层经过蒸纱定型后，可以有效避免回捻作用，使得基层表面更平整，再对基层进行洗涤，提高基层与抗菌层之间的连接强度，采用本申请的生产工艺生产的抗菌家居服布料的抗菌性能优异，抗菌层与基层之间的结合强度高，经过多次洗涤后，依旧能够保持优异的抗菌效果。

对比例
对比例1
一种家居服布料，与实施例6的区别之处在于，不包括抗菌层。
对比例2
一种抗菌家居服布料，与实施例6的区别之处在于：抗菌液中不包括聚醚胺，其它同实施例6。
对比例3
一种抗菌家居服布料，与实施例6的区别之处在于：抗菌液中不包括竹炭粉，其它同实施例6。
对比例4
一种抗菌家居服布料，与实施例6的区别之处在于：抗菌液中不包括壳寡糖，其它同实施例6。
对比例5
一种抗菌家居服布料，与实施例6的区别之处在于：抗菌液中不包括纳米银，其它同实施例6。
性能检测试验洗涤：将实施例和对比例制备的抗菌家居服布料在相同条件下洗涤，洗涤条件为5cm×5cm的布料浸泡到500mL水中，然后以1000r/min速度转动洗涤10min，洗涤结束后在125℃下烘干，除去布料上的细菌，此为洗涤一次，循环洗涤20次、50次、100次后，进行抗菌性能的测试；
抗菌性能测试：选择阴性的大肠杆菌和阳性的金黄色葡萄球菌为目标试验菌种；参照GB/T20944.3-2008《纺织品抗菌性能的评价第3部分振荡法》标准进行测试，计算抑菌率；
透气性：使用YC(B)461D-Ⅱ数字式织物透气测量仪，按照国家标准GB5453-1997《纺织品织物透气性的测定》进行测试，对同一块布料料三处不同的地方测量其透气性，取三次的平均值。
表1性能测试结果
结合实施例6和对比例1并结合表可以看出，本申请在基层上设置的抗菌层，具有较好的抑菌效果。
结合实施例实施例6-实施例8及对比例2并结合表1可以看出，加入聚醚胺的布料，抗菌性能好，未加入聚醚胺的布料，抗菌性能降低且经过水洗后，抑菌性降低的更快，说明聚醚胺的加入，一方面具有抑菌的作用，另一方面能够提高抗菌层与基层之间的连接强度，从而提高布料的水洗性能。随着聚醚胺含量的增加，抑菌性先增加，然后小幅度降低，聚醚胺含量过多，与基层之间的氢键作用太强，会影响抗菌液在基层上的涂覆，从而导致抑菌性下降。
结合实施例6，实施例9-10及对比例3并结合表1可以看出竹炭粉能给显著提高布料的抑菌性，竹炭粉含量过多时，竹炭粉易发生团聚，不易分散，导致抑菌性会出现降低。
结合实施例6，实施例11-12及对比例4并结合表1可以看出，壳寡糖能提高布料的抗菌效果。
结合实施例6，对比例5并结合表1可以看出，纳米银和纳米二氧化钛的协同作用，提高了抗菌的效果。
本申请的抗菌家居服布料，抗菌性能好、透气性好，且水洗后的布料依旧保持良好的抗菌效果和透气性。
本具体实施例仅仅是对本申请的解释，其并不是对本申请的限制，本领域技术人员在阅读完本说明书后可以根据需要对本实施例做出没有创造性贡献的修改，但只要在本申请的权利要求范围内都受到专利法的保护。
