padding: 0px; outline: 0px; max-width: 100%; font-size: 16px; overflow-wrap: break-word !important;">就像是“防冻剂”，抗冻蛋白能够结合小冰晶，并抑制大冰晶生长，进而保护细胞和血液在冰点下不结冰，并进行正常代谢，保证海嘴鱼在极地环境、雪蚤在厚厚的积雪下能正常生存。在新研发的耐冻蛋白纤维中，抗冻蛋白能捕获水分子或冰晶等，进而为蛋白质纤维提供“保护层”，提高了纤维的抗冻性。</span></p><p style="margin-bottom: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; overflow-wrap: break-word !important;"><br></p><p style="margin-bottom: 0px; outline: 0px; max-width: 100%; clear: both; min-height: 1em; overflow-wrap: break-word !important;"><span style="margin: 0px; padding: 0px; outline: 0px; max-width: 100%; font-size: 16px; overflow-wrap: break-word !important;">据测试，在零下40摄氏度的低温下，耐冻蛋白纤维中的冰结晶受到抑制，纤维更光滑、截面上的皱纹更少，因此也保持了较高的低温刚度和韧性，以及良好的机械稳定性，这使得用蛋白纤维制造具有出色抗冻性能的纺织品成为可能，比如在南极洲使用的绳索或北极极地服装、航空服等。</span></p><p style="margin-bottom: 0px;

padding: 0px; outline: 0px; max-width: 100%; font-size: 16px; overflow-wrap: break-word !important;">又如，恒天海龙股份有限公司等研发的一种新型多功能动物蛋白再生纤维素纤维，其原料来自动物的毛。上海帕兰朵纺织科技发展有限公司副总经理、教授级高级工程师方国平说，由于纤维的横截面呈C形中空，形状的饱满率和圆滑度好，从而使纤维具有了独特的截面形态。这种截面形态使得多功能动物蛋白再生纤维素纤维在微观结构上，实现了纤维素和蛋白质共存共融，使这款动物蛋白再生纤维素纤维具有了其他纤维不具备的多功能特性，比如良好的透气性和抗静电性，以及优异的吸湿发热性等。再配合独特的纺纱技术、织造技术和定型技术等，使该纤维技术成本和生产成本大幅下降，由此生产的纱线和针织面料与同类产品相比，性价比更高。</span></p></section></section></section></section></section></section></section></section></section></section></section></section></section></section></section></section></section></section></section></section></section>
