Description

一种智能感菌毛巾印花浆及生产工艺
技术领域
一种智能感菌毛巾印花浆及智能感菌毛巾,属于抗菌毛巾技术领域。
背景技术
普通的毛巾使用三个月每平方厘米的菌落数量超过300万,六个月就上升到600万数量级,大量易感染病菌会侵蚀皮肤。
发明专利CN107700247A公开了一种感菌变色印花油墨,其采用的技术手段是使用微胶囊包裹脂溶性色素,微胶囊感菌后会破裂露出色素而显示该毛巾已收到足量的菌落感染,不宜使用,但是,该方法一方面需要单独制备感菌微胶囊,制备工艺繁琐,要求高,难度大,成本高,另一方面,微胶囊壁厚趋于固定,难以控制其感菌敏感度,对于各种应用场景的毛巾仅能针对性具有一个感菌变色标准,普适性略低,并且,感菌胶囊破裂后即完成不可逆的变色过程,感菌效果为一次性,不适于需要循环使用的毛巾。
发明内容
本发明所要解决的技术问题是:克服现有技术的不足,提供一种可循环使用,且易于控制敏感度,天然环保,具有感菌功能且能够重复使用的智能感菌毛巾印花浆。
本发明解决其技术问题所采用的技术方案是:一种智能感菌毛巾印花浆,其特征在于:按重量份包括活性染料0.01~6份,碱剂0.5~4份,脂肪酸0.1~1份,对羟基联苯0.2~0.8份,甲基红0.003~0.008份,酚酞0.001~0.003份,溴代麝香草酚蓝0.005~0.01份,麝香草酚蓝0.001~0.003份,无水乙醇2~5份,聚丙烯酸糊料85~90份。
所述的碱剂优选为小苏打。
对羟基联苯能够感知50亿个污染源因子并触发变色警示,既能够捕捉到油脂、汗液、皮脂、污物等细菌浓度的信号,促使麝香无菌兰变向酚酞细菌红,同时还能在乳酸环境下发生变色,检测乳酸存在情况,加深感菌后的变色程度。
从而实现能够指示毛巾上细菌含量情况,而溴代麝香草酚蓝、麝香草酚蓝与甲基红等成分均可以通过水洗回复变色前状态,即实现了感菌指示的重复使用,并且,可以通过改变各感菌变色组分的浓度,调整该感菌变色印花的变色阀值,从而使该印花浆能够应用于不同使用环境的毛巾,避免过早变色或指示不准确,对感菌毛巾的指示性能更可控。
优选的,按重量份包括活性染料0.01~6份,碱剂0.5~4份,脂肪酸0.1~1份,对羟基联苯0.2~0.8份,甲基红0.005份,酚酞0.002份,溴代麝香草酚蓝0.006份,麝香草酚蓝0.002份,无水乙醇2~5份,聚丙烯酸糊料85~90份。
优选的重量份具有准确的感菌变色范围,变色效果更明显。
一种智能感菌毛巾生产工艺,其特征在于:包括以下步骤:设计描稿、印花、蒸化、烘干、整理、拉幅;其中,印花采用权利要求1或2所述的智能感菌毛巾印花浆根据设计描稿印花。
优选的,所述的印花步骤包括:将活性染料、聚丙烯酸糊料与碱剂混匀制得色浆,将对羟基联苯、甲基红、酚酞、溴代麝香草酚蓝、麝香草酚蓝与无水乙醇混匀制得助剂,印花时将色浆与助剂混匀后开始印花。
由于印花浆中多种成分易于感菌或受酸碱影响,上述的智能感菌毛巾印花浆优选随用随配,而色浆与其余助剂成分分开添加能够延长各自的储存时间,避免内部在印花前发生反应。
优选的,所述的整理步骤采用仙护盾抗菌剂进行整理。
上述智能感菌毛巾印花浆配合仙护盾银离子抗菌技术-Silvadur 930 FLEX(杜邦微生物技术),互相并不会发生反应,并且协同增效。仙护盾(SILVADUR)的可溶性聚合物系统会将银离子(而非金属颗粒)传递到被处理织物的表面,形成一个均匀保护层。增强了银离子在纤维表面的附着力,提高牢度,耐水洗性增加,可将低浓度银离子送到纤维表面,以控制产生异味的微生物生长,同时能使上述的智能感菌毛巾印花浆的印花部分在一定程度上隔离空气,避免空气中的酸碱成分使感菌印花发生慢反应而失去感菌功能,提高毛巾的感菌效果与使用寿命。
优选的,仙护盾抗菌剂在整理液中浓度为2~20g/L。
所述的浓度可以使毛巾的抗菌值达到6.5,在水洗20次后依然能够保证抗菌值6.2。并且尽可能降低用量有利于降低成本。
优选的,所述的蒸化步骤采用100~102℃蒸化。
优选的,所述的蒸化后采用水洗至布面pH为6~7。过高或过低的pH值都将影响颜色变化效果。
与现有技术相比,本发明所具有的有益效果是:能够在毛巾沾染一定量的细菌或代谢物后,精准指示毛巾的污染程度,并且感菌变色阀值更可控,适用于多种使用环境的毛巾,延长使用寿命;印花浆配制、使用更方便,成本更低,并且能够通过水洗再生,即经过水洗后恢复感菌前的颜色并恢复感菌变色能力,采用全天然原料,无伤害性,更适于日常生活使用。

印花步骤包括:按照以下实施例与对比例重量比例将活性染料、聚丙烯酸糊料与碱剂混匀制得色浆,将对羟基联苯、甲基红、酚酞、溴代麝香草酚蓝、麝香草酚蓝与无水乙醇混匀制得助剂,印花时将色浆与助剂混匀后开始印花。
整理步骤采用仙护盾抗菌剂进行整理,整理液添加SILVADUR™ 930 FLEX抗菌剂,抗菌剂浓度为10g/L;蒸化步骤蒸化温度采用100~102℃,蒸化后水洗至布面pH6~7,获得智能感菌毛巾。
实施例1
一种智能感菌毛巾印花浆,按重量份包括活性染料3kg(其中金黄3rs0.2kg大红p-b0.3kg 藏青bb2.5kg),碱剂2kg,脂肪酸0.5kg,对羟基联苯0.5kg,甲基红0.005kg,酚酞0.002kg,溴代麝香草酚蓝0.006kg,麝香草酚蓝0.002kg,无水乙醇3kg,聚丙烯酸糊料87kg。

对比例4
一种智能感菌毛巾印花浆,在实施例1的基础上,不添加酚酞,其他条件与实施例1相同。
性能测试
首先对上述实施例与对比例所得智能感菌毛巾进行耐摩擦色牢度、耐水洗色牢度、耐汗渍色牢度与耐皂洗牢度测试,均能够达到3级以上。
感菌能力测试,检测人员使用上述对比例、实施例所得智能感菌毛巾,检测人员分别于早八点与晚五点用清水清洗脸部与手部后,用智能感菌毛巾擦干,每条毛巾的测试实验连续不中断,至出现肉眼可见变色为止,记录一共经历擦拭使用的次数。
水洗能力测试,感菌能力测试后的智能感菌毛巾经过水洗后,再次经过感菌能力测试方法测试变色前使用次数。
测试结果见下表1。
表1 感菌能力
Figure DEST_PATH_IMAGE001
参照附图1、2,其中,“小鱼”图案为印花标准色,“小狗”图案采用智能感菌毛巾印花浆印花,图中“小鱼”图案在变色前后可以看出未出现变色现象(照片中色值深浅未变化);“小狗”图案颜色由鲜亮棕红色变为灰蓝色(照片中图案相较于“小鱼”图案变深色)。
根据表1,其中,实施例1~5能够在毛巾可接受的使用周期内适时变色,证明毛巾既能及时变色,又不会过早变色,并且经过水洗后变色能力下降不明显,其中实施例1在后续使用中第50次水洗后依然保持了使用次数10次的感菌能力。变色效果明显,不同感菌变色成分可以互补变色,即任意一种被监测成分(油脂、乳酸等)超过合理范围,即会发生明显变色,指示更准确,更易分辨。
对比例1、3、4的变色效果并不明显,“小狗”图案表现为由淡棕色变为棕绿色(棕蓝色),较难识别,并且对比例1、2明显超出了毛巾的合理使用周期;对比例2、3的智能感菌毛巾印花色浆缺少互补变色成分,受到水洗影响严重。
经检测,无荧光、无辐射、对皮肤无刺激、不含有害芳香胺、沾色牢度4~5级,完全达到婴幼儿安全级别。
以上所述,仅是本发明的较佳实施例而已,并非是对本发明作其它形式的限制,任何熟悉本专业的技术人员可能利用上述揭示的技术内容加以变更或改型为等同变化的等效实施例。但是凡是未脱离本发明技术方案内容,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、等同变化与改型,仍属于本发明技术方案的保护范围。
