Description

远红外布料及其制法和用途 技术领域
本发明涉及纺织类， 具体说是远红外布料及其制法和用途。 背录技术
现代物理学和医学研究证实， 远红外线对人体具有保健医疗作用， 远红外线 可使皮下组织的温度上升， 扩张微细血管， 促进血液循环， 强化血液及其它组织 之间的新陈代谢， 促进组织再生能力及抗痉挛能力。 同时可抑制知觉神经的异常 兴奋， 对自律神经的机能调节也有明显的效果。 因此与远红外线有关的医疗保健 器械成为近年来研究开发的热点。
近年来， 在常温下使用具有远红外发射作用的远红陶瓷， 制成具有医疗保健 作用的制品的发明也越来越多。 其中涉及远红外线医疗保健作用的服装的发明申 请也有报导， 如日本公开特许公报平 1 - 2 0 7 4 0 3 中公开了一种将远红外陶 瓷混人硅橡胶溶液， 然后将此溶液点状涂覆在普通布料的内表面， 然后使其硬化, 此布料用于制作手套、 袜子、 腹带等， 这些制品具有保健作用。
由于采用涂覆的方法加工出的保健制品无论在手感、 穿着舒适性、 还是耐洗 性方面存在许多的不足之处， 所以又出现了采用将远红外陶瓷粉添加在聚合物 ( 溶液） 中进行纺丝， 得到具有远红外放射性的纤维后， 再进一步加工成保健内衣 的发明专利申请， 如日本公开特许公报平 3 - 5 1 3 0 1 , 公开了将 3 0 ·(：下 4 . 5 - 3 0微米波长平均远红外发射率在 6 5 %以上的远红外陶瓷粉， 如丫 -氧化 铝、 α -氧化铝和氧化锆及氧化镁等中的一种与聚酰胺混合后作为芯层， 以聚酰 胺作为皮层， 熔融复合纺丝得到预取向长丝， 然后再进一步假捻加工成低弹型长 丝， 经针织或机织加工成布料， 再进一步裁剪缝制成内衣的方法， 由于采用了复 合纺丝工艺， 因而设备较复杂， 而且只对纤维迸行了假捻加工， 纤维的蓬松性仍 不理想 0 发明内容
本发明的目的在于采用更为便利的纺丝工艺， 提供一种具有良好保健性能、 手感和蓬松感及服用舒适性的远红外布料及其制法和用途。
本发明的目的是这样实现的： 在常规成纤聚合物， 如聚丙烯中添加 3 0 下 8 - 1 4 微米远红外发射率在 8 0 %以上远红外陶瓷粉， 混合均匀后， 制成纺丝 切粒， 然后直接在熔融纺丝机上纺成预取向长丝， 为了使制品具有良好的蓬松感, 以改善服装的手感和穿着舒适性， 采用假捻和网络加工的方法使长丝线上形成 1 0 - 3 0 个 / 米的网络及 1 0 - 3 0 %的弹性伸长， 最后以此纤维为原料经针织 或机织加工成步料。 所述的布料经裁剪、 缝制加工成远红夕 健服， 如远红外保健秋衣裤、 远红 夕 {^¾健背心、 远红夕 ^健短裤、 远红夕 健腹带和远红 N¾健乳罩等。
为了保证实现本发明的目的， 用于制造本发明的远红夕^健服的远红外陶瓷 粉应具有较髙的 8 -1 4微米红外线发射率， 之所以如此， 是因为人体做为一个 天然的远红外源， 在正常体温 3 6 . 5 'C下， 其远红外发射波谱的范围是 8 - 1 4 微米， 其最大光谱辐射出射度为对应的波长是 9 . 3 微米， 所以做为远红夕^ 健服， 要具有良好的医疗保健效果， 远红夕 健服的远红外线的波长必须与人体 最佳匹配， 因此其范围也必须在 8 -1 4微米。 氧化铝系、 氧化锆系和氧化镁系 及氧化钛系远红外陶瓷具有发射 8 ― 1 4微米波长远红外线的能力， 但仅使用其 中的一种做为远红外陶瓷粉， 往往很难得到较髙的远红外线的能力， 而这直接影 响远红夕 健服的医疗保健效果， 因而本发明采用上述氧化铝系、 氧化锆系、 和 氧化镁系及氧化钛系远红外陶瓷中的至少两种做为远红外陶瓷粉。 其目的是为了 使远红外陶瓷的 3 0 'C下 8 - 1 4微米远红外发射率在 8 0 %以
为了实现本发明的目的， 聚丙烯中所含的远红外陶瓷粉的重量以聚合物计， 最好在 1 -5 0 %之间， 较好地是在 2 -4 0 %之间， 最好在 3 -3 0 %之间， 远红外陶瓷粉的含量太少， 研制出的纤维的远红 H¾健性能太差， 而远红外陶瓷 粉的含量过高， 则易导致纺丝困难及后加工困难， 同时也会使纤维的使用性能下 降。 其中， 远红外陶瓷粉品选料中， 组份之间的比例 （氧化铝系： 氧化锆系： 氧 化镁系： 氧化钛系） 可以任意选自 1 : 1 : 1 : 1 -3 : 3 : 2 : 1 。
为了使添加有远红外陶瓷粉的聚丙烯具有可纺丝性， 聚丙烯中所含的远红外 陶瓷粉的平均颗粒直径应在 0 . 0 2 -1 0微米之间， 较好的是在 0 · 1 - 5 微 米之间， 最好是在 0 . 5 -2微米之间， 远红外陶瓷的粒径太小， 易出现颗粒之 间凝结， 影响纺丝性和纤维的使用性能， 而粒径过大， 则在纺丝中容易堵塞喷丝 ？ L造成断丝， 使纺丝困难。
除聚丙烯外， 本发明中所用的成纤聚合物也可以是任何具有足够高的分子量 的线性热塑性聚合物， 如聚乙烯、 聚己内酰胺、 聚己二酸癸二胺、 聚己二酸己二 胺和聚对苯二甲酸乙二酯等及以上述聚合物为主要成分的共聚物等， 但做为本发 明目的聚合物， 以聚丙烯为最好， 由于聚丙烯纤维具有良好的导湿、 抗菌、 抗蛀 性能， 因而在用作保健服材料时， 具有良好的穿着舒适性和使用耐久性。
本发明的远红夕 1^¾健服加工所用的纤维既可采用常规的方法， 也可以采用非 常规的方法在与普通化学纤维成形条件相似的工艺条件下制成预取向丝， 纺丝速 度可以在 5 0 0 -2 5 0 0 米 / 分之间选择， 喷丝板的孔数可以在 2 4 -7 2 孔 I扳之间选择， 喷丝孔的直径较好的是 0 . 2 5 -0 . 4 0 mm, 喷丝孔直径过 大或过小均不能得到性能理想的纤维， 喷丝孔的长径比最好在 3 ： 1 以上， 长径 比过小易造成纺丝过程中的熔体破裂， 使纺丝困难。
为了改善服装的手感和穿着舒适性， 在预取向丝的后加工过程中， 对纤维同 时进行了假捸和网络加工， 得到了具有网络结构的低弹长丝， 弹性伸长率为 5 - 5 0 , 网络数为 5 - 5 0个 / 米， 弹性伸长率较好的是 8 - 4 0 % , 最好的是 1 0 - 3 0 %, 网络数以 8 - 4 0个 / 米较好， 最好是 1 0 - 3 0 个 / 米。 弹性 伸长过小， 网络数过小， 织物的蓬松感较差， 而弹性伸长过大、 网络数过多则会 造成针织或机织加工困难， 以及使穿用耐久性下降， 后加工的速度可以是 5 0 0 - 1 0 0 0米 /分。
通过对预取向丝进行假捻和网络处理， 得到了具有良好弹性和蓬松性， 表面 光泽和蜡状感改善的远红外丙纶长丝， 以这种远红外丙纶长丝为原料， 在常规针 织或机织设备上进一步加工成布料后， 可裁剪、 缝制成远红夕 K¾健内衣裤、 三用 短裤和文胸等。
为了保证得到的远红外丙纶针织布具有良好的手感和服用舒适性， 针织面料 的密度应在 1 5 - 3 0针 / 寸之间较为合适， 最好在 2 0 - 2 5 针 / 寸之间选择。 加工成的面料的面密度取决于所用的纱线的旦^ Co 根据纱线旦数的不同， 可在 1 0 0 - 3 0 0克 /平方米之间变化， 织物的面密度在此范围内时， 对加工成的远 红夕 H¾健服的医疗保健效果没有影响。
为了要得到既具有良好的使用效果， 又具有良 的美观性的远红夕^健服， 针织布的结构可以是平纹， 也可以是罗纹， 还可以采用各种提花技术， 将其加工 为具有不同花型的面料。
远红外保健服的式样与常规服装没有明显的区别， 但为了保证远红夕 ^健服 所发射出的 8 - 1 4微米远红外线可被人体最佳吸收从而具有良好的医疗保健作 用， 通常将其加工成内衣使用， 因而常规的内衣式样均适合本发明的远红夕 ^健 服。
经中国医学科学院血液研究所、 血液病医院、 天津市第一中心医院、 天津市 第三医院等单位临床试验测试证实， 采用本发明组成和工艺加工出的远红外保健 服， 不但具有良好的 8 - 1 4微米远红外线发射作用， 而且均具有促进微循环和 血液循环的功能， 对由于微循环和血液行循环障碍弓 I起的各种疾病， 如肢体疼痛、 关节炎、 慢性劳损、 急性扭挫伤、 皮肤搔痒、 腿抽筋等具有十分明显的症状改善 和辅助治疗作用， 并且穿着舒适性良好。
这是由于采用本发明的组成和工艺加工出的远红外保健服在常温下可高效吸 收和发射出远红外线， 其中的 8 - 1 4微米远红外线对人体最有益、 最易被人体 吸收， 它与构成人体细胞的分子、 原子间振动频率一致， 可被细胞吸收， 引起共 鸣共振， 使分子内的振动加大， 活化组织细胞， 增加血流量， 促进微循环， 并提 供养分， 增进新陈代谢， 提高免疫力， 所以具有保健 能。 本发明的最佳实施方式
