摘要

耐用的阻燃、防紫外线、抗皱棉织物，不仅在日常生活中提供长期防火、防紫外线的保护，而且在穿着过程中保持其外观或美观。然而，如何用多功能助剂方便地制备出耐用的阻燃、抗皱、抗紫外线棉织物，仍然是一个很大的挑战。本文合成了一种新型的dopo基膦酸铵聚合物（SH）。将其作为“一石三鸟”整理剂，通过易烘交联工艺制备无甲醛、耐用阻燃、抗皱、抗紫外线棉织物。由于SH和纤维素之间的化学交联，经15% SH溶液处理的织物的折皱恢复角达到258.1°。SH的P/N协同作用和紫外线吸收能力分别显著提高了织物的阻燃性能和抗紫外线性能。经25wt % SH溶液处理后，织物的极限氧指数和紫外线防护系数分别为41.1%和285.4，按AATCC 61-2013 3A标准洗涤50次后，极限氧指数和紫外线防护系数仍保持在31.8%和189.4。SH通过促进炭的形成、淬灭自由基、稀释氧气和燃料来发挥阻燃作用。本研究不仅为棉织物“一石多鸟”整理剂的设计提供了新的思路，也为方便制备多功能高耐久棉织物提供了启发策略。

One stone, three birds: One-pot synthesis of DOPO-based ammonium phosphonate polymer for durable flame-retardant, anti-wrinkle and anti-ultraviolet cotton fabric

Durable flame-retardant, anti-ultraviolet and anti-wrinkle cotton fabric not only provides long-term protections from fire and ultraviolet ray in daily life, but also maintains its appearance or beauty during wear. However, it is still a great challenge to facilely prepare durable flame-retardant, anti-wrinkle and anti-ultraviolet cotton fabric with a multifunctional agent. Herein, we synthesized a novel DOPO-based ammonium phosphonate polymer (SH). It was used as a “one-stone-three-birds” finishing agent to prepare formaldehyde-free, durable flame-retardant, anti-wrinkle and anti-ultraviolet cotton fabric via a facile baking-crosslinking strategy. Thanks to the chemical crosslinking between SH and cellulose, the fabric treated by 15 wt % SH solution achieved a wrinkle recovery angle of 258.1°. The P/N synergy and ultraviolet absorption capacity of SH markedly enhanced the flame retardancy and anti-ultraviolet property of fabric, respectively. For the fabric treated by 25 wt % SH solution, the limiting oxygen index and ultraviolet protection factor were 41.1 % and 285.4, which still maintained at 31.8 % and 189.4 after 50 washing cycles following AATCC 61–2013 3A standard, respectively. SH played flame-retardant roles by promoting char formation, quenching free radicals, and diluting oxygen and fuels. This study not only proposes a novel insight for designing “many birds with one stone” finishing agent for cotton fabric, but also an inspired strategy to facilely prepare multifunctional cotton fabric with high durability.

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
