本申请请求 2013年 03月 05 日向中国国家知识产权局提交的、 专利申请 号为 201310069899.8的专利申请的优先权和权益,并且通过参照将其全文并入 此处。 技术领域
本发明涉及一种纺织纤维及纺织品, 特别是涉及一种保温隔热纤维及由该 纤维制成的纺织品。 背景技术
现有技术中, 绝大多数传统纺织纤维及纺织品的保温是通过增加纤维的用 量以及提高纤维纺织品的厚度和重量来提高其保温性能的; 例如, 目前市场销 售的主流保暖内衣均具有重量较大、 厚度较厚的问题, 在穿着的舒适性方面, 具有难以弥补的缺陷。
另外, 也有部分现有技术采用了蓄热材料来提高纤维纺织品的保温性。 所 谓蓄热材料就是一种能够储存热能的新型化学材料。 它在特定的温度下发生物 相变化, 并伴随着吸收或放出热量, 可用来控制周围环境的温度, 或用以储存 热能。 其原理和技术方案与保温隔热具有显著的差异性; 例如, 吸湿发热纤维 便是其中一种。 吸湿发热纤维具有良好的吸湿性, 能将人体排出的水分子的动 能转化为热能, 从而提高体感温度, 由于温度的升高又使得排出的水汽更易蒸 发掉。 但是, 吸湿发热纤维对纺织品保温性的提高也比较有限, 同时, 该种纤维 的成本也较为高昂。 发明内容
本发明的目的是提出一种保温性更好、 成本更加低廉、 并且方便制造、 易 于产业化实施的保温隔热纤维及由该纤维制成的纺织品。
为实现上述目的, 本发明提供了一种保温隔热纤维, 在常规纺织纤维中添 加占常规纺织纤维总重量 0.1 ~ 3%重量份的纳米单元提高纤维的保温率, 所述 纳米单元包括 300 ~ 8000纳米的微粒子, 所述的微粒子包括 Al、 Zn、 Sb、 Na、 Fe、 Si中任意两种或多种的混合物。
优选地, 所述常规纺织纤维包括化学纤维, 所述的化学纤维包括人造纤维 和 /或合成纤维。
更优选地, 包括占总重量 1.5 ~ 3%重量份的 300 ~ 4000纳米的微粒子。 进一步, 在所述的纳米单元中, 所述微粒子包括 300 ~ 500重量单元的 A1 和 30 ~ 100重量单元的 Na, 或者 30 ~ 500重量单元的 Sb和 10 ~ 500重量单元 的 Fe, 或者 100 ~ 1000重量单元的 Zn和 50 ~ 3000重量单元的 Si中至少一组 的混合物。
优选地, 所述保温隔热纤维包括占总重量 0.1 ~ 1.5%重量份的 4000 ~ 8000 纳米的微粒子。
更优选地, 在所述的纳米单元中, 所述微粒子包括 300 ~ 500重量单元的
A1和 10 ~ 500重量单元的 Fe,或者 100 ~ 1000重量单元的 Zn和 30 ~ 100重量 单元的 Na, 或者 30 ~ 500重量单元的 Sb和 50 ~ 3000重量单元的 Si中至少一 组的混合物。 进一步, 在所述的纳米单元中, 所述的微粒子还包括 50 ~ 100重量单元的 K、 100 ~ 500重量单元的 Sn和 50 ~ 100重量单元的 S。
本发明的另一目的在于提供一种保温隔热的纺织品, 该纺织品至少包括部 分上述的保温隔热纤维。
本发明的又一目的在于提供一种含有纳米单元的纤维在制备保暖纺织品 中的应用, 所述含有纳米单元的纤维为上述任意的保温隔热纤维。
基于上述技术方案, 本发明的优点是:
由于本发明在常规纺织纤维中加入了一定比例的 300 ~ 8000纳米微粒子纳 米单元, 使得本发明的纤维在对比相同克重和织法的纺织品时, 能够大幅提高 纺织品的保温性和克罗值, 并且本发明相对于现有的保温纤维而言, 具有制造 成本较低、 制造工艺筒单、 易于工业化生产等等优点。
本发明的附加方面和优点将在下面的描述中部分给出,部分将从下面的描 述中变得明显, 或通过本发明的实践了解到。 附图说明

参见表 1和图 1, 其中示出本发明一种保温隔热纤维保温效果的检测实施 例。
(1)检测名称: 保温性实验

保温率(% ) = ( 1 -a/b ) 100
( 4 )检测单位: 日本法定检测机构 般财团法人 BOKEN纺检品质 评价机构东部事业所
(5)检测样品:
5.1-本发明纤维样品:
在常规纺织纤维中加入了约占常规纺织纤维总重量 2.9%重量份纳米单元 的纺织纤维, 该纳米单元的微粒大小约 300纳米; 所述微粒子包括 500重量单 元的铝(A1)和 30重量单元的钠(Na), 以及按照现有技术需要添加的其他微 量元素。
本发明的纳米单元可以采用现有纺织纤维制造技术中的任意一种进行添 加。 本发明所采用的制备方法包括如下步骤: A、 将天然的高分子物质或无机 物 (如: 粘胶纤维)、 或者合成的高分子物质或无机物 (如: 锦纶或腈纶)制 成纺丝熔体或溶液; B、 在所述纺丝熔体或溶液中添加上述的纳米单元 A1和 Na; C、 经喷丝机构挤出, 形成纤维。 其他工艺步骤与现有技术的纤维制备方 法相同, 在此不再赘述。
需要说明的是,上述纳米单元 A1和 Na的重量单元比率也可以为其他任意 比率, 本发明的发明人进行了大量的重复试验, 各种比例的纳米单元均使得纤 维制品具有较好的保温性, 本实施例仅选择了众多实验中的一组实验数据做出 说明 (下同)。
此外, 本发明的 粒子可以为常温状态下的氧化物或氮化物, 也可以为其 他能够稳定存在的形式, 例如化合物或单体。
需要说明的是: 本发明所述的 "重量单元"优选为 "微克 /公斤" 的重量比 值, 当然也可以根据实际需求量按照其他的重量单位进行称量(下同)。
5.2 -对比实验:
对比实验 1的样品: 永旺销售的吸湿发热内衣, 检测方法与上述的 "实验 方法" 相同;
对比实验 2的样品: 优衣库销售的吸湿发热内衣, 检测方法与上述的 "实 验方法" 相同;
对比实验 3的样品: 饰梦乐销售的吸湿发热内衣, 检测方法与上述的 "实 验方法" 相同; 对比实验 4的样品:伊藤洋华堂销售的全羊毛内衣,检测方法与上述的 "实 验方法" 相同;
对比实险 5的样品: 优衣库销售的 100 %羊绒衫, 检测方法与上述的 "实 验方法" 相同。
( 6 )检测结果:
表 1: 纺织品保温性实测数据
Figure imgf000008_0001
上述检测结果的保温率对照图参见附图 1所示, 其中, 从本发明与对比试 验 1、 2、 3的比较中可以看出: 在相同的克重下, 本发明纤维制得的纺织品的 保温率, 是其他市场销售吸湿发热内衣保温率的 2倍多; 需要说明的是: "克 重" 是纺织丝绸产品评价常用单位, 是每平方米织物的重量, 单位是 "克 /平方 米"; 克重是针织面料的一个重要的技术指标。
进一步, 对比试验 1、 2、 3中纺织品的保温率已经比市场上绝大多数内衣 的保温率高出很多。 根据我国 《FZ/T 73022-2004针织保暖内衣》 的规定, 保暖内衣的成品外 包装上均须标示保温率、含量等指标, 其中 "保温率"不得低于 30%; 事实上, 绝大多数所谓的保暖内衣, 均是通过增加克重数(即通过增加内衣的厚度和重 量)来提高其保温率。
而由本发明保温隔热纤维制得的纺织品, 所获得意想不到的技术效果是: 本发明采用普通内衣的克重数, 却达到了远远高于保暖内衣的保温率。
甚至于参见表 1和图 1中, 从本发明与对比试验 4、 5的比较中可以看出: 在远小于羊毛制品和羊绒制品的克重下, 本发明纤维制得的纺织品的保温率, 比羊毛制品和羊绒制品的保暖率还要高出许多。 换言之, 本发明保温隔热纤维 制得的内衣, 可以具有替代羊毛衫和羊绒衫的用途。
需要说明的是本发明的 "保温隔热" 与现有技术中 "蓄热保温" 之间的差 另1 J : 蓄热是只由外部热源 (或内部产生热量的物质)向蓄热产品提供能量, 并 由蓄热产品进行储存热量的过程; 而本发明保温隔热纤维的工作原理是将人体 的热量尽可能多地经由纳米单元反射回来, 并与外界环境保持隔离。 此外, 本 发明的上述实验均是针对内衣纺织品的保温性实验, 并无外界热源(例如阳光 等光源)的能量补充或供给, 因此, 本发明亦属于含有纳米单元的纤维在制备 保暖纺织品中的应用。 实施例 2:
本实施例与上述实施例的不同之处在于,检测样品是在常规纺织纤维中加 入了约占常规纺织纤维总重量 0.2%重量份纳米单元的纺织纤维, 该纳米单元 的 粒大小约 8000纳米; 所述 粒子包括 300重量单元的铝( A1 )和 100重 量单元的钠 (Na ), 以及 100重量单元的钾(K )、 100重量单元的锡(Sn )和 100重量单元的硫(s )。 本发明的纳米单元可以采用现有技术中的任意一种在 纤维制造的工艺中进行添加。

本实施例的检测结果为: 克重为 150 (克 /平方米)的含有本发明保温隔热 纤维的纺织品, 其保温率为 43.5 % ; 其他对比实验与实施例 1相同, 在此不再 赘述。
本实施例检测结果的保温率对照图: 略。 实施例 4:
本实施例与上述实施例的不同之处在于,检测样品是在常规纺织纤维中加 入了约占总重量 1.6%重量份纳米单元的纺织纤维, 该纳米单元的微粒大小约 5000纳米;所述微粒子包括 30重量单元的锑( Sb )和 500重量单元的铁( Fe ), 以及 80重量单元的钾( K )、 300重量单元的锡( Sn )和 70重量单元的硫 ( S ), 本发明的纳米单元可以采用现有技术中的任意一种在纤维制造的工艺中进行 添力口。
本实施例的检测结果为: 克重为 150 (克 /平方米)的含有本发明保温隔热 纤维的纺织品, 其保温率为 43.1 % ; 其他对比实验与实施例 1相同, 在此不再 赘述。
本实施例检测结果的保温率对照图: 略。
此外, 本实施例还采用了另一种保温隔热纤维的制备方法, 包括纺织纤维 化纤母粒的制备步骤, 在化纤母粒的制备过程中, 添加上述的纳米单元, 然后 生产出纤维。 本实施例纤维制备方法的其他工艺步骤与现有技术的纤维制备方 法相同, 在此不再赘述。 实施例 5:
