Description

抗变色罗马布的制备工艺
技术领域
本发明涉及罗马布制造领域，更具体的说，它涉及一种抗变色罗马布的制备工艺。
背景技术
随着经济的发展和社会的进步，人们追求健康、时尚和自然的生活方式已成为必然趋势，对服装除了遮羞、保暖、防寒等基本需求外，对舒适性的要求越来越高。针织物是通过线圈连接而成，在受力时线圈会变形而获得良好的自然弹，且面料蓬松从而获得柔软的手感、卓越的透气性和良好的亲肤性，因此针织物穿着比梭织物较为舒适，迅速获得了市场的广泛认可。但是针织物纱线的状态自由，容易变形、起球。
罗马布俗称打鸡布，是一种纬编针织面料，由双面大圆机进行织造，是四路一个循环，布面没有普通双面布平整，略微有点轻微并不太规则的横条，具有卓越的弹性、透气性、手感和吸湿性，贴身穿着的舒适性很高。
但是现有技术中生产的罗马布，由于涤纶的染色性差，往往需要 对涤纶多次上色才能染色均匀，因此在夏天天气炎热，且使用者出汗较多的情况下，容易出现罗马布被汗水浸黄问题。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种抗变色罗马布的制备工艺，其通过纱线预处理、蒸汽定型、编织、胚布处理、粗处理、固色、细处理以及检验打包等步骤，使得罗马布在制成之后耐热性得到了增强，减小了对汗水的吸收，进而减小了变黄的可能。
为实现上述目的，本发明提供了如下技术方案：一种抗变色罗马布的制备工艺，包括以下步骤：
一、纱线预处理：将锦纶和氨纶纱线浸泡在浓度为200-240g/L的烧碱溶液中浸泡一小时，同时在烧碱溶液中加入粒径为4~10μm的水镁石粉末。，取出冲洗干净，并甩干；
二、蒸汽定型：将步骤一中的纱线放置入蒸汽罐中，抽真空后向蒸汽罐内充入混有占蒸汽总量0.05%wt的丙烯酸树脂的水蒸气，使真空罐内部温度保持在120-140℃，保温一小时；
三、编织：采用大圆机将锦纶和氨纶编织成胚布；
四、胚布处理：将胚布浸入35-45℃碱液中浸泡，碱液包括去油剂80g/L、渗透剂40g/L以及烧碱200g/L，采用水浴的方式并以2℃/min的速度将碱液升温至80℃，保温60min后，取出胚布，冲洗并甩干；
五、粗处理：将粗胚拉幅定型，车速20m/min，超喂量20％，扩幅率5％；
六、固色：将胚布连续在浓度为70g/L、粘度为1000Cs的聚丙烯酸甲酯浸轧三次，然后在58-62℃温度下预烘5min，随后在115-120℃温度下焙烘10min；
七、细处理：将胚布浸轧在处理液中10min，保持处理液温度位于38-42℃之间，处理液包括220g/L的有机硅柔软剂、浓度为80g/L的烷基磷酸酯二乙醇胺盐以及余量水，然后将坯布经过热定型机170℃,机速40r/min, 超喂30％；
八、检验、打包。
通过采用上述技术方案，在步骤一中，由于纱线经过碱液的浸泡，所以纱线的纤维表面会被腐蚀出凹槽，但同时烧碱溶液中加入了水镁石粉末，即加入了大量氢氧化镁粉末，而氢氧化镁呈白色，且其脱水温度为400℃+，也具有极好的耐热性，所以在纱线经过碱液腐蚀出凹槽的同时，水镁石粉末也会填充入纱线上的凹槽内，在纱线冷却后，水镁石粉末会与纱线限位稳定的连接在一起，这样一来，纱线的耐热性就得到了改善，在夏季也就更难变黄了。
较佳的：步骤一中，水镁石粉末与水的重量比为1:50~65，水镁石粉末的粒径为4~10μm。
通过采用上述技术方案，水镁石粉末粒径为4~10μm时，能够较好地填满纤维表面由碱液处理而产生的凹坑，水镁石粉末粒径小于4μm时，容易漂浮在烧碱溶液上，使水镁石粉末不容易填入凹坑中，水镁石粉末粒径大于10μm时，水镁石粉末的粒径过大，导致水镁石粉末难以填入凹坑中，不仅影响填充效果，也影响了纱线的强度。
较佳的：步骤一中烧碱溶液中加入含量为2~7%的脂肪醇聚氧乙烯醚。
通过采用上述技术方案，脂肪醇聚氧乙烯醚的醚键不易被酸、碱破坏，稳定性较高，水溶性较好，耐电解质，易于生物降解，泡沫小，作为一种表面活性剂，可以使纱线表面残留的油污杂质更好地溶解在浸泡池内，减少纤维表面凹坑中的油污杂质，使水镁石粉末可以更好的填充凹坑，使纤维的强度和耐热性更好，使罗马布在夏季高温天不容易变黄，使罗马布质量更好。
较佳的：步骤一中，纱线冲洗完成之后，在纱线表面均匀喷洒成膜喷雾，静置50-60分钟。
通过采用上述技术方案，成膜喷雾可以在纱线表面形成一层保护膜，使凹坑中的水镁石纤维不容易脱落，同时保护膜对纱线起到了一定的保护作用，使纱线不容易磨损和断裂，在编织成布的过程中不容易因纱线断裂而影响制备的进程，同时也使罗马布在使用的过程中不容易因纱线断裂而破损，使罗马布的质量更好。
较佳的：步骤一中，氨纶纱线的制作步骤为：将黑涤纶单染，将单染后的黑涤纶包氨纶制成黑涤纶包氨纶纱线。
通过采用上述技术方案，将涤纶先单独染色，将染色后的涤纶包棉纶制成黑涤纶包棉纶纱线，从而避免涤纶包棉纶后再染色，造成棉纶染色过度的问题。
较佳的：步骤一中，棉纶的制作步骤为：同时将涤纶和人造棉AB纱制成涤纶与人造棉复合的棉纶。
通过采用上述技术方案，将涤纶先单独染色，将染色后的涤纶包棉纶制成黑涤纶包棉纶纱线，从而避免涤纶包棉纶后再染色，造成棉纶染色过度的问题。
较佳的：步骤六中，焙烘结束后，采用双氧水2-3g/L、纯碱2-3g/L、精炼剂1-2g/L、乳化剂2-4g/L、柔软剂4-5g/L以及余量水的去油剂，以3℃/min的升温速度将温度升至98℃，保温30min，然后以2℃/min的降温速度将温度降至60℃。
通过采用上述技术方案，能够将胚布上的油脂层通过去油剂去除，同时配合升温，加快了油脂的乳化反应，且柔软剂能够使得胚布更加柔软，减小了胚布在经过双氧水洗涤后***的可能。
较佳的：步骤三中，所述棉纶以棉毛编织方式编织于织物正反面， 所述氨纶以大圆机上下针全吃的方式分别覆盖于棉纶正反面。
通过采用上述技术方案，能够使得罗马布的拉伸回复性增强强，且使罗马布更加耐褶皱。
综上所述，本发明相比于现有技术具有以下有益效果：1. 通过纱线预处理、蒸汽定型、编织、胚布处理、粗处理、固色、细处理以及检验打包等步骤，使得罗马布在制成之后耐热性得到了增强，减小了对汗水的吸收，进而减小了变黄的可能。
