Abstract

Polyethylene terephthalate (PET) fibers are widely used in many fields, but their flammability and molten droplet characteristics during combustion pose a significant safety risk. To address the issue, a novel approach was developed to enhance the flame retardant and anti-dripping performances of PET fabric through a combination of dyeing and mussel-inspired strategy. First, PET fabric was directly dyed with heme chloride (HC) to produce dyed PET fabric (HC-PET), which was then treated by a mussel-inspired tannic acid-based flame retardant (TAPP) and an impregnation-drying-curing process to prepare flame retardant PET fabric (FR-PET). The results indicated that the total heat release (THR) and peak smoke production rate (PSPR) of FR-PET were decreased by 22.8 % and 49.7 %, respectively, and the limiting oxygen index (LOI) was increased from 21 % to 29.8 %, showing good flame retardant properties. Additionally, the UV resistance and antibacterial performances of FR-PET were also significantly improved. In summary, this study provided a feasible approach for the preparation of multifunctional PET textiles with dyeing, flame retardant, anti-dripping, UV resistance and antibacterial performances.

基于氯化血红素染色和贻贝启发策略的阻燃防滴涤纶织物的制备

聚对苯二甲酸乙二醇酯（PET）纤维广泛应用于许多领域，但其可燃性和燃烧时的熔融液滴特性带来了重大的安全隐患。为了解决这一问题，我们开发了一种新的方法，通过染色和贻贝的结合策略来提高涤纶织物的阻燃和防滴性能。首先用氯化血红素（HC）对涤纶织物进行直接染色，得到染色涤纶织物（HC-PET），然后用贻贝激发单宁酸基阻燃剂（TAPP）和浸渍-干燥-固化工艺制备阻燃涤纶织物（FR-PET）。结果表明，FR-PET的总放热率（THR）和峰值产烟率（PSPR）分别降低了22.8%和49.7%，极限氧指数（LOI）由21%提高到29.8%，具有良好的阻燃性能。此外，FR-PET的抗紫外线性能和抗菌性能也得到了显著提高。综上所述，本研究为制备具有染色、阻燃、防滴、抗紫外线和抗菌性能的多功能涤纶纺织品提供了一条可行的途径。

期刊介绍： The aim of this international journal is to analyse and publicise the progress and current state of knowledge in the field of organic coatings and related materials. The Editors and the Editorial Board members will solicit both review and research papers from academic and industrial scientists who are actively engaged in research and development or, in the case of review papers, have extensive experience in the subject to be reviewed. Unsolicited manuscripts will be accepted if they meet the journal''s requirements. The journal publishes papers dealing with such subjects as: • Chemical, physical and technological properties of organic coatings and related materials • Problems and methods of preparation, manufacture and application of these materials • Performance, testing and analysis.
