Development of multi-functional cotton surface for sportswear using nano zinc oxide

ABSTRACT

This paper reports the development of multi-functional cotton knitted fabric by two-stage process. Cotton knitted fabric was finished with in situ generated nano zinc oxide (nano-ZnO) followed by electrospraying Arkophop FFR a non-fluorocarbon-based hydrophobic chemical. Electrospraying was carried out with different flow rates (0.01 and 0.02 mL/min) and durations (1– min) with the help of microprocessor controlled syringe pump. The fabric was analyzed for its antimicrobial, UV protective, and moisture management (MMT) properties. FTIR study confirmed the formation of hydrophobic chemical finish on one surface of cotton fabrics. Scanning electron microscope observation showed the presence of nano-ZnO and hydrophobic finish on the electrosprayed surface of the cotton fabric. One-way moisture transport rating of the treated fabric using MMT test was found to be very good for 0.01 mL/min flow rate of the hydrophobic chemical for duration of 3 min using an optimized voltage of 20 kV and the distance of 15 cm between the nozzle and the collector. In situ generated nano-ZnO positively influenced the MMT properties of the treated cotton fabric.

摘要

本文报道了多功能棉针织物的两步法开发。用原位生成的纳米氧化锌（纳米ZnO）和电喷雾喷涂ARKOPHOP FFR完成了棉针织物的制备。在微机控制的注射泵的帮助下，采用不同流量（0.01和0.02ML/min）和持续时间（1～5分钟）进行电喷雾。对织物的抗菌性、紫外线防护性和水分管理性能进行了分析。FTIR研究证实棉织物的一个表面形成疏水性化学整理。SEM观察表明，在织物电喷雾表面上存在纳米ZnO和疏水性整理剂，采用水分管理试验对织物的水分传输率进行了测定，发现其对疏水性化学剂的持续时间为0.01 mL/min。使用20kV的优化电压和喷嘴和收集器之间的距离为15厘米的3分钟。原位生成纳米ZnO对棉织物的水分管理性能有积极的影响。
