Description

一种涤纶慢回弹填料的生产工艺 技术领域
本发明具体涉及一种涤纶慢回弹填料的生产工艺。
背景技术
目前市面上的普通人造纤维枕，由人造化纤所组成，而且人造纤维是最普及、物美价廉之材质，所以使普通人造纤维枕的成本低廉，另外人造纤维枕易清洗，但由于化纤材质缺乏弹性、不透气，用久了会变形、结块，使枕头高低不平。现在很多人都喜欢使用记忆枕，记忆枕材质为高密度、吸震、可透气的记忆科技棉，记忆科技棉采用纯天然软木经过几十道特殊工艺制成，软木颗粒具有柔软、弹性好、重量轻、吸汗性好、透气性高的特点，使用者还可根据需要随意改变枕头的形状，比较有利于颈椎的保健。但是记忆科技棉在生产过程中经过了几十道的特殊工艺，这几十道的特殊工艺中难免要加入一些化学品，无法保证这些化学品不会对人体造成不良的影响。而且一般的记忆科技棉都不抗老化，不能放在太阳下暴晒，更不能清洗，长此以往，就给细菌营造了一个很好的生长环境，影响人体健康。
公知的涤纶枕芯填料，在生产过程中，为了兼具枕芯的软性及刚性，通常手段是通过对6.67dtex单孔64mm、8.33dtex四孔60mm、10.00dtex60mm七孔等涤纶三维卷曲棉进行优化组合。但因其之间的卷曲程度(波高、宽及频率)没有变化，且纤维长短差异很小，粗细虽有差异，但梯度较小，这类枕芯填料，纤维之间的空隙较大、填料的密度较小，枕芯使用一段时期后，由于长时间承受到来自人体头部重量，导致填料间隙变小、密度增大而使枕芯高度降低，纤维缠绕、结团而使枕芯变形，蓬松度下降，影响枕芯的使用价值。
发明内容
发明目的：本发明提供一种涤纶慢回弹填料的生产工艺。
技术方案：一种涤纶慢回弹填料的生产工艺，包括如下步骤：手工混棉→一次开松→二次开松→灌装→称重→封口；
所述手工混棉步骤中，将如下3种规格大小的纤维进行混棉：
填料①：重量比为30～50％，长度为60～64mm，粗细为6～10dtex涤纶三维卷曲棉，其卷曲程度高；
填料②：重量比为20～30％，长度为15～20mm，粗细为5～6dtex涤纶三维卷曲棉，其卷曲程度中；
填料③：重量比为10～20％，长度为10～15mm，粗细为3～5dtex涤纶三维卷曲棉，其卷曲程度低；
所述一次开松步骤中，喂棉高度5-8cm，喂棉速度1.0-1.5米，针布轮转速720-860转/分钟；
所述二次开松步骤中，喂棉高度8-10cm，喂棉速度1.5-2.0米，针布轮转速2400-3260转/分钟。
作为优化：所述手工混棉步骤中，混棉的时间为：30-40min。
作为优化：所述一次开松步骤中，针布轮转速770转/分钟。
作为优化：所述二次开松步骤中，针布轮转速2880转/分钟。
作为优化：所制成的产品规格为：48*74*700g，全棉14.6tex*14.6tex 524根/10cm*394根/10cm的漂白面料。
有益效果：本发明使用长度为10-20mm，细度为3-6dtex涤纶或涤纶混合三维卷曲棉与公知的涤纶或涤纶混合三维卷曲棉进行优化混配。混配时，将本案涤纶三维卷曲棉与公知的涤纶三维卷曲棉在粗细、长短、卷曲程度、数量方面设计成梯度关系。所以，填料③可以进入填料②的纤维空隙之间，填料②可以进入填料①的纤维空隙之间，相似形纤维混合后，形成了立体结构，当受到来自外部压力时，在立体支撑效应下，降低了枕芯变形程度，同时，通过对三种填料粗细程度、长短、弯曲程度、数量关系的优化，避免了因填料密度过度增加，导致的枕芯蓬松度的过度下降。其次，由于填料②、填料③长度的减小，增强了填料的分散性，降低了纤维缠绕、结团程度。再次，枕芯在加压、释压条件下，由于上述的“梯度关系”造成了不同填料之间抗压及回复性能的“梯度关系”的形成，加上纤维之间的摩擦力的关系，枕芯变形的速度变得缓慢，形成“慢回弹”现象，从而提高了枕芯服用的舒适性。
