Silk sericin protein is a natural high-molecular-weight compound that contains eighteen types of amino acids. It is non-toxic, biodegradable, and biocompatible, with simple preparation methods and low cost. It finds widespread application in functional clothing, medical and pharmaceutical fields, tissue engineering, and more. Nano-titanium dioxide, on the other hand, possesses non-toxic, self-cleaning, antibacterial, and deodorizing properties. To develop multifunctional textiles with deodorization, UV protection, and good thermal and mechanical properties, this study utilized a compounding method to modify citric acid-pretreated cotton fabrics through a two-dipping and two-padding process using a blend finishing solution of silk sericin protein and nano-titanium dioxide. Observations of the microstructure before and after fabric finishing, along with evaluations of deodorization, UV protection, and thermal properties, revealed that controlling the proportion of the silk sericin protein/nano-titanium dioxide blend finishing solution can result in a smooth surface of the modified cotton fabric. This modification not only enhances the fabric’s UV protection and tensile strength but also improves its thermal properties while imparting certain deodorization capabilities. Comprehensive analysis concludes that using silk sericin protein and nano-titanium dioxide for modifying cotton fabric to prepare multifunctional textiles with deodorization, UV protection, and good thermal and mechanical performance is feasibly viable.

This study evaluates the wrinkle behaviour and wrinkle resistant properties of cotton fabrics dyed by Direct Blue 2B in the presence and absence of nano-TiO2 particles. A finishing process on samples was performed before dyeing by means of 1,2,3,4-butanetetracarboxylic acid (BTCA) and sodium hypophosphite (SHP) using a pad dry cure method. Such experiments as wrinkle recovery test (AATCC-128), water drop test and dye fastness determination (ISO 105-C01) were conducted to understand how current treatment impacted the cotton fabrics’ properties. Finally, samples were characterised using the X-ray diffractometery method to scrutinise how crystallinity changes and dominates the structural parameter (wrinkle behaviour) of cotton fabrics. Furthermore, scanning electron microscopy (SEM) was used to visualise the surface variations of the samples before and after dyeing process. The results showed that the wrinkle resistant of cross-linked fabrics have been improved after direct dyeing. Furthermore, levelness dyeing and good fastness properties of dyes on cross-linked fabrics were observed.
