但是，上述专利中防护服采用的面料一般透气性较差，工作人员穿上后舒适感较差。

S1将若干受热膨胀纱线缠绕于高温纱线，以构成可膨胀耐高温纱线，再利用该可膨胀耐高温纱线经纬交织成可膨胀层；
S2将该可膨胀层胶粘于复合层；
S3将阻燃层胶粘于该可膨胀层。
在本发明的一实施例中，所述受热膨胀纱线的制备方法是：将可膨胀石墨与耐高温胶粘剂混合，制得混合液，再将该混合液涂覆于耐高温纱线表面并固化。

实施例1
请参照图1，本实施例提供一种耐高温面料，其包括依次层叠地设有阻燃层1、可膨胀层2和基底层3。
基底层3由涤纶纱线、尼龙纱线混合织成，如涤纶纱线作为纬线，尼龙纱线作为经线，通过经纬纺织制成复合面料。
阻燃层1由阻燃纱线织成，该阻燃纱线可以由聚丙烯腈阻燃纤维或芳纶阻燃纤维制成，纤维高温面料的阻燃层1直接面向热源。
可膨胀层2由可膨胀耐高温纱线21织成，具体的，如图2所示，可膨胀耐高温纱线21包括耐高温纱芯211和受热膨胀纱线层212，受热膨胀纱线213包括耐高温纱线和可膨胀石墨，耐高温纤维为聚四氟乙烯纤维或聚酰亚胺纤维。制备受热膨胀纱线213时，将可膨胀石墨与耐高温胶粘剂混合，制得混合液，再将该混合液涂覆于耐高温纱线表面并固化。耐高温胶粘剂为磷酸盐类胶粘剂或硅酸类胶粘剂。本领域技术人员根据实际需要设定固化温度，但固化稳定需低于可膨胀石墨的膨胀温度。通过在耐高温纱芯211外部缠绕包裹一层受热膨胀纱线213，缠绕方式如图3所示，以构成受热膨胀纱线层212，当可膨胀耐高温纱线21受热温度达到膨胀温度后，受热膨胀纱线层212膨胀，致使可膨胀耐高温纱线21整体线径增大。
在缠绕成可膨胀层2时，其中一部分可膨胀耐高温纱线21作为经线，另一部分可膨胀耐高温纱线21作为为纬线，通过经纬交织织成，而且需控制相邻两根经线或相邻两根纬线之间的间隔，如图4所示，以相邻的两根经线为例，设相邻两根经线之间间隙的宽度为d，设单根可膨胀耐高温纱线21膨胀后的半径与初始半径的差为Δr，则d需满足：d<2Δr。当可膨胀耐高温纱线21未膨胀时，两根经线之间的具有宽度为d的间隙，以便增强面料的透气性；当可膨胀耐高温纱线21遇热膨胀后，如图5-6所示，因相邻两根经线之间没有足够空间让两根可膨胀耐高温纱线21完全膨胀，则两根膨胀后的可膨胀耐高温纱线21相互挤压，两根膨胀后的可膨胀耐高温纱线21之间的间隙消失，以减少外部的热空气经可膨胀耐高温纱线21之间的间隙流入面料内侧，降低面料的透气性。
实施例2
一种耐高温面料的制备方法，用于制备实施例1的耐高温面料，制备方法包括如下步骤：
S1将若干受热膨胀纱线213缠绕于高温纱线，以构成可膨胀耐高温纱线21，再利用可膨胀耐高温纱线21经纬交织成可膨胀层2；
S2将可膨胀层2胶粘于复合层；
S3将阻燃层1胶粘于可膨胀层2。
在本实施例中，受热膨胀纱线213的制备方法是：将可膨胀石墨与耐高温胶粘剂混合，制得混合液，其中耐高温胶粘剂为磷酸盐类胶粘剂或硅酸类胶粘剂。再将混合液涂覆于耐高温纱线表面并固化。其中耐高温纤维为聚四氟乙烯纤维或聚酰亚胺纤维。
实施例3
一种耐高温面料防护服，利用实施例1中的耐高温面料制成。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
