摘要： Disclosed herein are a flexible aerogel sheet and a preparation method therefore via a dry process. The aerogel sheet includes a needle-punched non-woven fabric, and aerogel particles charged in the fabric. The preparation method includes: scattering aerogel particles in a needle- punched non-woven fabric web; preliminary needle punching the non- woven fabric web; main needle punching the preliminary needle-punched non- woven fabric web; and laminating the main needle -punched non- woven fabric web by thermal treating surfaces thereof. With the use of needle punching, the aerogel particles can be charged in voids in the non- woven fabric, and upper and lower non- woven fabric webs can be firmly attached to each other by bridged fibers, without a binder. Also, the needle punching provides the aerogel sheet with pressure -resistance and load-resistance and prevents deformation of the aerogel sheet due to damage to the aerogel particles. The aerogel sheet having no binder has no risk of clogging in aerogel pores, resulting in superior thermal-insulation property.
摘要翻译：因此，本文公开了柔性气凝胶片及其制备方法。气凝胶片包括针刺无纺织物和装入织物中的气凝胶颗粒。制备方法包括：在针刺无纺织物纤维网中散射气凝胶颗粒; 初步针刺无纺布网; 主针针刺预先穿刺的无纺布网; 并通过其热处理表面层叠主针 - 无纺布幅材。通过使用针刺，气凝胶颗粒可以填充在无纺布中的空隙中，并且上下无纺织物网可以通过桥接纤维彼此牢固地附接，而不需要粘合剂。此外，针刺提供了气凝胶片的耐压性和耐负载性，并且防止气凝胶片由于气凝胶颗粒的损坏而的变形。没有粘合剂的气凝胶片没有气凝胶孔堵塞的风险，导致优良的隔热性能。

摘要： The present invention provides an emulsion-removing device which can advantageously be used in a fibre production method, and in which an emulsion for fibres used during the spinning of a filament yarn is removed from the filament yarn rather than from a non-woven fabric, thereby achieving far better removal efficiency than when emulsion is removed in the nonwoven fabric state, and the present invention also relates to an emulsion-removing method for emulsion-impregnated filament yarns using the device.
摘要翻译：本发明提供一种乳液去除装置，其可有利地用于纤维生产方法中，并且其中用于在长丝纺丝期间使用的纤维的乳液从长丝纱线而不是从无纺织物中去除，与非织造物状态下除去乳液时相比，除去效率好得多，本发明还涉及使用该装置的乳液浸渍长丝的乳液除去方法。
