Description

一种喷胶棉絮片的制备方法
技术领域
本发明涉及喷胶棉技术领域，尤其是涉及的是一种喷胶棉絮片的制备方法。
背景技术
喷胶棉又称喷浆絮棉，其常规工艺是将纤维原料梳理制成单层薄网，然后铺叠成絮片，通过在絮片两面喷洒粘合剂，使纤维间的交接点被粘接，经烘燥、固化而成。现在使用较为广泛的喷胶棉原料纤维为聚酯纤维，其优点是抗皱性和保形性很好，具有较高的强度与弹性恢复能力，坚牢耐用、抗皱免烫、不粘毛。但聚酯纤维内部大分子无亲水性基因，所以吸湿透湿能力低，使用久了还会产生异味。
常规工艺生产的喷胶棉絮片其层与层之间只是简单的堆叠关系，层与层纤维间的缠绕交叉不充分，导致粘合后的稳定性不足，容易错动、分层。
专利CN2011101365894公开了一种可水洗棉絮的制作方法，该方法通过在润棉机上设置绝缘纸对棉絮表层进行碳化成粒的熨磨处理，提高了絮片的密度，降低其蠕动性。但是因为絮片表面不平整，这种碳化过程难以把控，导致次品率过高，同时加工过程中产生的灰黑粉末、细微颗粒等对絮片的污染问题，也未能得到解决。
发明内容
本发明的目的在于克服上述不足，提供一种蓬松度高、整体性好，具有吸湿除臭功能的喷胶棉。
为实现上述目的，本发明的技术解决方案是：一种喷胶棉絮片，包括基体和功能体，所述基体采用以高卷曲中空聚酯短纤为主体的纤维絮片，并在该絮片基体内的各单层薄网的表面粘附由低熔点纤维包覆的功能母粒；所述功能母粒是以硅酸钠溶液和稀无机酸生成的原硅酸为载体，载体质量份数10-15份，添加质量份数3-5份二氧化钛、2-4份麦饭石粉、1-3份蒙脱石粉二次造粒而成，造粒粒径D90≤0.1mm。
一种喷胶棉絮片的制备方法，其特征在于，包括如下步骤：
1)、把稀释后的油剂以雾点状均匀喷洒到原料纤维中，堆积24h-48h，油剂附着量为0.3-0.5%；
2）、将经过处理的各组分原料纤维按混合比称重，分别单独通过预开松机进行粗开松和除杂；
3）、输棉风机将通过预开松后的各组分原料纤维送入多仓混棉机中进行混合，然后经过主开松机进一步精开；
4）、给棉机将精开后的混纤定量、均匀地喂入多道夫梳理机,经过进一步分梳、除杂和混合，杂乱成网制成一定规格面密度的均匀薄网；
5）、输送帘将制成的薄网送入圆网滚筒压辊式浸渍机，在薄网背面辊压上一层由低熔点纤维包覆的功能母粒，通过热定型机使功能母粒固定在薄网背面；继续向前输送薄网，过程中将薄网进行正反面倒置和冷却，再在薄网原正面上固定一层功能母粒，输送给后道工序；
6）、铺网机将经过双面处理的单层薄网铺叠成所需宽度及厚度的絮片，在负压下通过高频震动机共振，使絮片纤维结构更蓬松，同时让重叠薄网的各层表面上的功能母粒互相嵌套，最后经过双面喷胶、烘干定型、压光工序后，进行切边、裁剪、卷取。
通过采用上述的技术方案，本发明的有益效果是：本产品纤维层间附着具有吸湿除臭的功能母粒，可以有效排湿并吸附异味，提高喷胶棉的服用性。同时，使用辊压工艺和热粘工艺固定的功能母粒，牢固性好，分布均匀，在震动嵌合后上胶，所制成的喷胶棉各棉层间不易错动、分层，整体性优秀。
具体实施方式
下面通过优选实施例对本发明的技术方案做进一步说明。
