This study introduces hydraulic spray (HS) atomizing system as new resource-efficient continuous dyeing-finishing method for wool fabric. Here, wool fabric was dyed and finished by using commercial dyes and finishes through either one-step or two-steps HS method. Results obtained from color strength (K/S), color difference (ΔE) and color fastness analysis presented the apprehension of HS method in dyeing of wool fabric with different GSM and dyes. Finishing performance of wool fabric was measured through water contact angle analysis. Analysis shows that, the finishing performance of HS method were substantial to reach water contact angle as high as 145° while maintaining high fastness to wash and abrasion. Between one-step and two-steps HS method, one-step method showed better performance with high resource efficiency compared to two-steps method. Results from statistical analysis shows no statistical significance of fabric weight, type of dyes, and finishes to the performance of new HS method which is crucial for true-scale industrial implementation and scaling up of this process. The findings of this report are of great importance as it presents a greener alternative to the conventional resource-intensive dyeing-finishing methods of wool fabric.
本研究引入液压喷雾（HS）雾化系统，作为一种新的资源节约型连续染整方法，用于羊毛织物。在此，通过一步法或两步法 HS 法，使用商业染料和整理剂对羊毛织物进行染色和整理。通过颜色强度（K/S）、色差（ΔE）和色牢度分析得到的结果表明，HS 法在不同克重和染料的羊毛织物染色方面具有优势。通过水接触角分析来测量羊毛织物的整理性能。分析表明，HS 法的整理性能显著，可达到高达 145°的水接触角，同时保持高耐洗和耐磨色牢度。与两步法相比，一步法在资源效率方面表现更好。统计分析结果表明，织物重量、染料类型和整理剂对新 HS 法的性能没有统计学意义，这对于真正规模的工业实施和该过程的扩大至关重要。本报告的发现非常重要，因为它为羊毛织物传统的资源密集型染整方法提供了一种更环保的替代方案。
