Abstract
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.
