Description

一种适用于不同温度的被芯制备方法
技术领域
本发明涉及一种被芯的制备方法，特别是公开一种适用于不同温度的被芯制备方法。
背景技术
床上芯被类产品占家纺产品中的比重很大，根据使用季节主要分为冬被、夏被、春秋被三类。被子材质有棉质、羊毛、蚕丝、化纤、鹅绒等。羽绒被的重量较轻，透气干爽、排湿性强；羊毛被吸湿保干、冬暖夏凉；蚕丝被手感顺滑，柔软亲肤，防螨抗菌，抗过敏，但其保暖性和轻盈性很难兼顾；棉纤维较细并有天然卷曲，所以其保暖性较好，但随着使用时间的延长，棉被变得不再蓬松，保暖性下降；化纤被相对棉被在满足保暖性的同时，可以具有更轻的重量，而相对于蚕丝被、羊毛被来说价格相对便宜些，更为大众所接受。
被芯是每天夜晚都和人们身体接触的产品，但因体积较大，往往不具有多变轻巧的性能，常常出现夏季使用的被子太厚，冬天使用的被子太薄的现象；同一季节的温度有时波动也较大，当季使用的被子有时盖上过热有时过冷，消费者总觉得找不到一款很合适的被子。
发明内容
本发明的目的在于解决现有技术中存在的问题，提供一种适用于不同温度的被芯制备方法；制得的纤维能够适用于不同温度下的被芯，提高使用舒适度，同时能够起到不同程度的保健助眠作用，既符合了环保可持续的发展理念，又满足了消费者的实际需求。
本发明是这样实现的：一种适用于不同温度的被芯制备方法，包括如下步骤：（1）分别制备抗静电聚酯纤维、植物中药粘胶纤维、腈纶纤维和大豆蛋白改性聚乙烯醇纤维；
（2）按照质量比将10~20%的抗静电聚酯纤维、30~50%的植物中药粘胶纤维、10~15%的腈纶纤维、30~35%的大豆蛋白改性聚乙烯醇纤维均匀混合。
步骤（1）中，通过共聚法对聚酯纤维进行改性：按重量比将1~3%的抗静电剂、0.5~1%磺酸盐或无机盐、96.0 ~ 98.5 %的聚酯切片共混，得到抗静电聚酯纤维。
所述抗静电聚酯纤维的质量比电阻为（2.1~2.3）×108Ω·g/cm2。
步骤（1）中，所述植物中药粘胶纤维的制备方法为：量取100mL去离子水4份，再称取芦根提取物、连翘提取物、知母提取物和夏枯草植物提取物各20~30g，分别加入去离子水中，用玻璃棒搅拌至溶解；按照取芦根提取物、连翘提取物、知母提取物和夏枯草植物提取物的溶液比例为（4~8）:（2~4）:（1~2）:（1~2）混合制得混合中药提取物混合液；再将混合中药提取物混合液与粘胶纺丝液按照（1~1.5）:（10~15）的比例共混，用搅拌器搅拌，直至均匀后过滤，静置脱泡后进行纺丝，得到植物中药粘胶纤维。
步骤（1）中，对所述腈纶纤维进行亲水改性处理：按照质量比，在82 ~ 87 %的腈纶纤维中，加入4~6%的浓度为2~3mol/L的氢氧化钠溶液、9~11%的浓度为1~1.5mol/L的乙醇、0.06~0.08%的交联剂，对腈纶纤维进行处理，水解时间25~30min，温度设置为80~90℃。
所述交联剂在甘油、海藻酸盐、2,4-二丙烯酰胺基苯磺酸（DABS）、丙烯酸或丙烯酸羟乙酯中任选一种。
本发明的有益效果是：通过一定的研发工艺过程充分提炼天然纤维的医疗保健特性，并将制得的纤维应用在消费者每天都会接触的睡眠被芯中，具有很高的实际应用价值和绿色环保性。
