Description

一种升温蓄热的纤维及其制备方法和紡织品 技术领域
本发明涉及一种紡织纤维及其制备方法, 特別是涉及一种升温蓄热的 纤维及其制备方法和紡织品。 背景技术
传统纤维及纺织品的保温是以阻止身体所发出的热逃逸为主。 随着科 学的发展, 人们也研制除了部分具有发热功能的纤维, 例如:
1. 电热纤维
日本试制的一种保温服装材料, 是利用电热材料参与组成的复合纤维, 其原理如同电热毯, 利用导电纤维通电使纤维发热, 以达到取暖的效果。 用该纤维制成的服装, 外形似一件薄薄的单衣, 其实为一件电热衣, 能源 来自随身携带的可充电电池, 在寒冷的冬季里, 其源源不断的热量, 足以 抵御严寒。
此种电热纤维的缺陷在于, 制造成本高昂, 需要携带充电电池进行供 电, 日常生活中使用起来颇为不便。
2. 太阳绒
太阳绒是根据太空棉原理制成的新一代具有代表性的材料。 它是将传 统的 100 %羊毛纤维充分绒化、 蓬松后置于两层软镜面之间, 使其形成薄厚 可控的热对流阻挡层(气嚢), 其导热系数极低, 同时对人体的热射线有反射 作用, 实现了双重保暖的功效。 由于气嚢中气体含量占 90 %, 因而太阳绒 既轻便柔软又保暖。 其单位体积内纤维量比棉花少 2 / 3, 比羽绒少 4 / 5, 制成的服装美观而不臃肿。 经检测其克罗(clo)值为 3.062。 两层镜面上有可 开闭的微孔, 如同皮肤的毛孔, 热时可张开散热, 冷时又可关闭保温, 温 度可调且具有透气性, 是秋冬季的理想衣料。
此种太阳绒材料也存在有制造工艺复杂, 成本高昂, 难以产业化等缺 陷。
3. 化学保温、 调温纤维
有人利用化学方法制取保温、 调温纤维。 例如有一种附有一层不透水 的薄膜, 内装钛酸钠的纺织品, 当钛酸钠受热后会液化贮热, 其贮热能力 比水强 60倍, 从而使体感温度下降; 而遇冷时钛酸钠会固化, 同时将吸收 的热量散发出来。
此种材料在制成紡织品后, 容易在日常生活中由于各种刮蹭、 碰撞而 产生泄漏, 因此, 其实用性还有待于进一步提高。 发明内容
本发明的目的是提出一种制造方便、 成本低廉、 易于产业化实施的升温蓄 热纤维及其制备方法和纺织品。
为实现上述目的, 本发明提供了一种升温蓄热的纤维, 所述的纤维包括常 规纺织纤维和占总重量 0.1 3%重量份的纳米单元, 所述纳米单元包括 300 ~ 8000纳米的微粒子, 所述的微粒子包括硅、 钛、 锑中至少两种的混合物。
优选地, 所述常规紡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 50 ~ 3000重量单元的硅 和 500 ~ 10000重量单元的钛。
优选地, 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 50 ~ 3000重量单元的 硅和 500 ~ 10000重量单元的钛。
优选地, 在所述的纳米单元中, 所述的微粒子还包括 30 500重量单元的 锑。
本发明的另一目的在于提供一种遇光快速升温并蓄热的纺织纤维的制备 方法, 所述制备方法包括如下步骤: A、 将天然的高分子物质或无机物、 或者 合成的高分子物质或无机物制成纺丝熔体或溶液; B、 在所述紡丝熔体或溶液 中添加上述的纳米单元; C、 经喷丝机构挢出, 形成纤维。
本发明的又一目的在于提供一种遇光快速升温并蓄热的纺织纤维的制备 方法, 所述制备方法包括紡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。
本发明的再一目的在于提供一种遇光快速升温并蓄热的紡织品, 其特征在 于: 该紡织品至少包括部分上述的纤维。
基于上述技术方案, 本发明的优点是: 由于本发明在常规紡织紆维中加入了一定比例 300 ~ 8000纳米的微粒子纳 米单元, 使得本发明的紆维在相同的光照时间和光照强度下, 具有预料不到的 遇光快速升温效果, 同时, 本发明的紆维在光照停止后, 比常规的化学纤维还 具有更好的蓄热性能, 并且本发明相对于现有的发热紆维而言, 具有制造成本 较低、 制造工艺简单、 易于工业化生产等等优点, 是在低温环境下较好的新型 发热纤维材料。 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
