Linen fabric as a natural fiber is one of the most popular textile products globally due to its excellent moisture absorption, antistatic, and antibacterial characteristics. However, it is still challenging to improve the color strength and utilization rate of reactive dye inks for printed linen fabrics. Herein, we proposed a polymer treatment agent to construct a new surface on linen fabric through a padding process, containing hydroxyethyl cellulose (HEC), sodium carbonate (Na₂CO₃) and urea. Then the fabric inkjet-printed with reactive dye inks. The results indicated that the HEC treated inkjet-printed linen fabric produced a higher performance with a satisfying fixation rate, more in-depth, and brighter color effect than sodium alginate (SA) treatment. SEM, wettability analysis, XPS and FTIR results revealed that the HEC treatment agent formed a film structure of the fabric to creat new surfaces with more hydrophobic of 46.5° contact angle and 0.9 s wetting time. XRD demonstrated no significant effect of HEC treatment on the aggregate structure of linen fiber. Also, the printed linen fabrics exhibited a satisfying color fastness and breaking strength.

作为天然纤维的亚麻织物由于其优异的吸湿，抗静电和抗菌特性，已成为全球最受欢迎的纺织品之一。然而，提高用于印刷亚麻织物的反应性染料油墨的色强度和利用率仍然是挑战。在本文中，我们提出了一种聚合物处理剂，它通过填充工艺在亚麻织物上构建新的表面，其中包含羟乙基纤维素（HEC），碳酸钠（Na ₂ CO ₃）和尿素。然后用活性染料墨水喷墨打印织物。结果表明，与藻酸钠处理相比，HEC处理的喷墨印花亚麻织物具有更高的性能，令人满意的固色率，更深的色彩效果和更明亮的色彩效果。SEM，润湿性分析，XPS和FTIR结果表明，HEC处理剂形成了织物的薄膜结构，以形成具有46.5°接触角和0.9 s润湿时间的更大疏水性的新表面。XRD显示HEC处理对亚麻纤维的聚集体结构没有显着影响。而且，印刷的亚麻织物表现出令人满意的色牢度和断裂强度。
