Purpose

Cotton is one of the most common nature textile fiber that is widely used in clothing, bedding and decorative fields due to its comfort. However, the cellulosic cotton fiber has its own drawbacks. Cotton fiber belongs to flammable material with the limiting oxygen index (LOI) value about 18% that restricts its applications. Cotton fiber is easy to crease during the repeat wearing and laundering process that will influence the wearability. Therefore, it is very important to improve the flame retardancy and anticrease performance of cotton fabric.

Design/methodology/approach

In this study, flame retardant and anticrease multifunctional modifications of cotton fabric were conducted by one-step pad–dry–cure process using eco-friendly phytic acid and 1, 2, 3, 4-butanetetracarboxylic acid.

Findings

The results of limited oxygen index (LOI) values and vertical burning test indicate that the flame retardancy of modified cotton fabric was greatly improved. The LOI value of modified cotton fabric reached 30.8% when the usage of phytic acid was 12%. The crease recovery angle was over 250° of the modified cotton fabric revealing good anticrease performance.

Originality/value

This research provides a novel feasible cost-effective one-step method for the multifunctional modified cellulosic fiber using eco-friendly chemical agents.

使用环保植酸和1,2,3,4-丁烷四羧酸的一步工艺多功能改性棉织物

目的

棉是最常见的天然纺织纤维之一，因其舒适性而被广泛用于服装、床上用品和装饰领域。然而，纤维素棉纤维也有其自身的缺点。棉纤维属于易燃材料，极限氧指数（LOI）值在18%左右，限制了其应用。棉纤维在反复穿着和洗涤过程中容易起皱，影响穿着性。因此，提高棉织物的阻燃和抗皱性能非常重要。

设计/方法/方法

在本研究中，采用环保植酸和 1,2,3,4-丁烷四羧酸通过一步浸轧-干法-固化工艺对棉织物进行阻燃和抗皱多功能改性。

发现

有限氧指数（LOI）值和垂直燃烧试验结果表明，改性棉织物的阻燃性有很大提高。当植酸用量为12%时，改性棉织物的LOI值达到30.8%。改性棉织物的折皱回复角超过250°，显示出良好的抗皱性能。

原创性/价值

本研究为使用环保化学试剂的多功能改性纤维素纤维提供了一种新的可行的、具有成本效益的一步法。
