Description
技术领域
本发明涉及纺织领域,尤其涉及一种防酚黄变粘合衬及其生产方法。
背景技术
随着服装面料的多样化以及人们对服装要求和欣赏水平的提高,对于服装衬布的要求也越来越高。市场上常规的30D、50D衬布一般都不耐酚黄变,特别是普通共聚酰胺热熔胶(PA)涂层的衬布产品更容易在储藏、运输以及在和含有酚类物质接触后产生黄变,与服装面料粘合后影响到浅色服装面料本来的色彩。
发明内容
本发明针对普通共聚酰胺树脂涂层的粘合衬容易发生酚黄变影响面料色彩的问题,提供一种防酚黄变粘合衬及其生产方法。
本发明的目的可以通过下述技术方案来实现:一种防酚黄变粘合衬及其生产方法,包括如下步骤:精炼、酸洗:溢流染色机将染缸内水升温至85~90℃后,基布投入染缸中与水一同循环转动,转动过程中加入水和助剂配置成的精炼液及烧碱,然后升温至100~120℃,精炼20~30分钟后排液,再加入冷水和冰醋酸,升温至50~70℃,洗涤15~25分钟后排液,最后溢流水洗5~15分钟后出布,其中,溢流洗出布前调整染缸内的PH为4~6,保持布面为弱酸性,染料按照小样所配颜料比例加入;脱水、开幅:上述精炼、酸洗过的基布先经过脱水设备脱去水分,然后在自动开幅机上进行开幅;定型:在定型设备的浆槽内加入由水、助剂和酸配置成的整理液,使上述脱水、开幅过的基布浸轧整理液后,在180~200℃的温度下,使基布烘干、定型,速度为30~45米/分钟;涂层:使上述定型过的基布经过涂层机,在基布的表面涂覆点状的抗酚黄变共聚酰胺树脂,然后再经过烘箱焙烘、烧结,冷却收卷完成衬布涂层。
进一步地,所述基布为30D或50D机织全涤平纹布。
进一步地,所述精炼液的成分为金属离子螯合剂0.3~0.5克/升、浴中柔软剂0.3~0.5克/升、表面活性剂0.1~0.3克/升、氢氧化钠2~10克/升、退浆剂0.3~0.6克/升、以及水。
进一步地,所述定型步骤中,所述整理液中的成分为有机硅柔软剂10~20克/升、防静电剂0.1~1.5克/升、渗透剂0.1~0.3克/升、柠檬酸5~10克/升、以及水。
进一步地,所述涂层步骤中,将定型过的基布经过双点涂层机,先利用圆网转移的方式将底浆以点状均匀地涂覆在基布表面上,再在浆点表面撒上粉状的抗酚黄变共聚酰胺树脂,然后通过吹吸设备去除多余的抗酚黄变共聚酰胺树脂,只使基布上有底浆的地方保留抗酚黄变共聚酰胺树脂,再进行红外加热,使底浆干燥并固着于基布表面上,然后进入烘房使得抗酚黄变共聚酰胺树脂烧结熔融并固着于浆点和基布之上。
其中,所述圆网的目数为26目,孔径为0.23mm;所述粉状的抗酚黄变共聚酰胺树脂的直径分布范围为80~140um。所述基布上的底浆和抗酚黄变共聚酰胺树脂的浆粉总量为7~8g/㎡。所述红外加热的温度为180~200℃;所述烘房的温度为160~200℃,速度为35~45米/分钟。
一种防酚黄变粘合衬,基于上述的防酚黄变粘合衬的生产方法生产而成;所述防酚黄变粘合衬包括基布和双点涂层,所述基布为30D或50D机织全涤平纹布,所述双点涂层由底浆和抗酚黄变共聚酰胺树脂构成,所述底浆呈点状均匀固着于基布表面上,所述抗酚黄变共聚酰胺树脂呈散点状地固着于底浆浆点和基布表面上。
与现有技术相比,本发明的优点在于:区别于一般的常规机织热熔粘合衬,解决了使用普通粘合衬因为酚黄变容易造成较薄浅色面料变色的问题,基布采用30D或50D机织全涤平纹布,经过精炼、酸洗、定型,使得基布的PH在4~6,再经过脱水、开幅、定型和双点涂层,其中,双点涂层时采用抗酚黄变共聚酰胺热熔树脂,最终使得产品的抗酚黄变测试性能达到4~4.5级。此衬布用于较薄浅色面料的粘合。
附图说明
图1为本发明中双点涂层工艺的示意图。
图中标注如下:
1为烘箱,2为回收装置,3吹风装置,4为撒粉装置,5为刮浆刀,6为圆网,7为底浆,8为支撑底辊,9为震动打布辊,10为基布,11为浆点,12为粉状共聚酰胺热熔树脂,13为粘在浆点上的抗酚黄变共聚酰胺树脂。
具体实施方式
以下结合附图详细说明本发明的具体实施方式,使本领域的技术人员更清楚地理解如何实践本发明。尽管结合其优选的具体实施方案描述了本发明,但这些实施方案只是阐述,而不是限制本发明的范围。
双点涂层工艺参见图1,生产中基布10经过圆网6和支撑底辊8的间隙后,浆料从圆网6的网孔中被刮浆刀5刮涂转移到布面上,基布10继续前进,在撒粉装置4处,被撒上一层粉状抗酚黄变共聚酰胺树脂12,然后经震动打布装置的震动打布辊9震打后,使粉状抗酚黄变共聚酰胺树脂12均匀地撒在基布10上,浆点11与浆点11之间的多余的粉状抗酚黄变共聚酰胺树脂12会经过吹风装置3吹除、回收装置2吸走,使其均匀地分布在浆点11上。然后再经过烘箱1焙烘、烧结,使得底浆7固着在基布10上,底浆7和基布10上呈点状间隔分布粘在浆点上的抗酚黄变共聚酰胺树脂13,最后经过冷却收卷完成涂层加工。其中,所谓底浆7是一种含有丙烯酸脂或聚氨酯成分乳液加水加增稠剂调整而成的具有一定粘稠度和流动性的胶体。

涂层:使上述定型过的基布经过双点涂层机,先利用圆网(圆网的目数为26目,孔径为0.23mm)转移的方式将底浆以点状均匀地涂覆在基布表面上,再在浆点表面撒上粉状的直径分布范围为80um~140um抗酚黄变共聚酰胺树脂,然后通过吹吸设备去除多余的抗酚黄变共聚酰胺树脂,只使基布上有底浆的地方保留抗酚黄变共聚酰胺树脂,浆粉总量为7g/㎡,再进行红外加热,温度为180℃,使底浆干燥并固着于基布表面上,然后进入烘房,烘房的温度为160℃,速度为35米/分钟,使得抗酚黄变共聚酰胺树脂烧结熔融并固着于浆点和基布之上。
