Multifunctional finishing of cellulosic/polyester blended fabrics

Area of Science:

• Materials Science
• Textile Chemistry
• Nanotechnology

Background:

• Textile finishing aims to impart multi-functional properties to fabrics.
• Developing efficient and eco-friendly finishing systems is crucial for the textile industry.
• Cotton/polyester and viscose/polyester blends are widely used fabrics requiring advanced functionalization.

Purpose of the Study:

• To develop innovative finishing systems for cotton/polyester and viscose/polyester blends.
• To impart multi-functional properties such as easy care, antibacterial, and UV-blocking.
• To investigate the influence of various finishing agents and treatment sequences on functionalization.

Main Methods:

• Utilized nano-hybrids: silver nanoparticles/polyvinyl pyrolidone (Ag-NP's/PVP) and zinc oxide nanoparticles/hyperbranched polyamide-amine (ZnO-NP's/HBPAA).
• Employed citric acid as a cross-linker and incorporated Basic Blue 9, chitosan, β-CD, Neem-oil, Lavender-oil, or 4-hydroxybenzophenone.
• Studied different treatment sequences and concentrations of active ingredients.
• Confirmed surface modifications and composition using SEM and EDX analysis.

Main Results:

• Achieved easy care, antibacterial, and UV-blocking properties in the treated fabrics.
• Demonstrated that the type and concentration of loaded active ingredients govern the imparted properties and wash durability.
• Identified optimal finishing system parameters for enhanced fabric functionality.
• Characterized the surface morphology and elemental composition of the modified textiles.

Conclusions:

• Developed effective finishing systems for multi-functional textile properties.
• Highlighted the importance of ingredient selection and treatment parameters for performance and durability.
• Provided insights into the interaction modes and surface modifications occurring during the finishing process.
