Cotton fabric with excellent antibacterial properties was obtained by treated with polyamide-amine (PAMAM) dendrimers as a carrier and silver nitrate as an antibacterial agent. The antibacterial cotton fabrics were prepared by the methods of one-bath process and two-bath process. Antibacterial activity of cotton fabrics treated by two different methods was good, but the antibacterial durability of cotton fabric treated with two-bath process was better than that treated with one-bath process. After 50 washing cycles, cotton fabric treated with two-bath process still had good antibacterial property and its inhibitory rate to Gram-positive S. aureus and Gram-negative E. coli was over 99 %. It was found that the breaking strength retention of finished cotton fabrics was 85.83 % and the decrease of cotton fabrics’ whiteness index was about 15 %.

As far as the value addition of textile is concerned, flame retardancy of textile materials is considered to be one of the most important properties in textile finishing by both industries as well as academic researchers. Flame-retardant property with thermal stability was imparted to cotton by using green coconut ( Cocos nucifera Linn) shell extract, a natural waste source of coconut. Coconut shell extract was analyzed by high-performance liquid chromatography, Fourier transform infrared spectroscopy, energy-dispersive spectrometry and its phytochemical analysis was also carried out. The coconut shell extract (acidic after extraction) was applied in three different pH (acidic, neutral, and alkaline) conditions to the cotton fabric. Flame-retardant properties of the untreated and the treated cotton fabrics were analyzed by limiting oxygen index and vertical flammability. The study showed that all the treated fabrics had good flame resistance property compared to that of the untreated fabric. The limiting oxygen index value was found to increase by 72.2% after application of the coconut shell extract from alkaline pH. Pyrolysis and char formation behavior of the concerned fabrics were studied using thermogravimetric analysis and differential scanning calorimetric analysis in a nitrogen atmosphere. The physicochemical composition of the untreated and coconut shell extract treated cotton fabrics were analyzed by attenuated total reflection–Fourier transform infrared, scanning electron microscope, and energy-dispersive X-ray spectroscopy. Also, treated cotton fabric showed natural brown color and antibacterial property against both Gram-positive and Gram-negative bacteria. The durability of the flame-retardant functionality to washing with soap solution has also been studied and reported in this paper.

In this paper, a new kind of antibacterial cotton fabric containing patchouli oil microcapsules was investigated. The patchouli oil microcapsules were prepared using a complex coacervation procedure and grafted onto cotton fabric by chemical crosslinking method, along with 1,2,3,4-butanetetracarboxylic acid (BTCA) was utilized as the crosslinking agent. The surface and morphology of fabrics were characterized by using scanning electron microscope (SEM). Fourier transform infrared spectrometry (FTIR) was used to study the formation of ester bonds between BTCA and hydroxyl groups of cotton and patchouli oil microcapsules. The releasing characteristics and antimicrobial durability of the antibacterial fabrics were also investigated by releasing test and laundering test. The results showed that the patchouli oil microcapsules were grafted onto cotton fabric by the role of crosslinking agent BTCA and the treated fabric represented persistent effect, slow releasing performance and washable antibacterial properties. After 30 days, the patchouli oil in the microcapsules was still remained on the fabric and the releasing amount was near 50%. About 72% antibacterial rate of the fabric for staphylococcus aureus and candida albicans could be obtained after washed 30 times, furthermore, no formaldehyde releasing can be found. It is suggested that chemical crosslinking method would provide a potential application in functional finishing by microcapsules for cotton fabric.

Superhydrophobic antibacterial cotton fabric can be widely applied in outdoor clothing, hospital bedding, and other fields. However, the existing manufacturing methods are difficult or complicated. Herein, a facile and straightforward fabrication strategy is proposed via a one-step hydrothermal method to construct micro-nanometer hierarchical structure with low surface energy on fabric. In an appropriate amount, 1H, 1H, 2H, 2H-perfluorooctyltriethoxysilane (PFOTES) and tetrabutyl titanate (TBT) were mixed in a hydrothermal reactor to generate titanium dioxide. Meanwhile, the PFOTES agent was hydrolyzed and condensed, bonded with titanium dioxide, and finally grafted onto the fiber together. Morphology and elements results demonstrated that the fabric surface was covered by the TiO2 nanoparticles with superhydrophobic coating. The chemical bonds of Si-O-Ti, Ti-O-C, and Ti-O-Ti revealed the structural relationship between TiO2 with PFOTES and cotton fibers. The water contact angle of the fabric obtained can reach to 168°. The fluorinated-TiO2 cotton fabric showed high antibacterial properties in visible light against E. coli and S. aureus. This simple method of preparing superhydrophobic and antibacterial fabric exhibited great potential in the field of functional textiles such as outdoor garments and hospital-related applications.

Herein, the amino-capped TiO2 nanoparticles were synthesized using tetrabutyl titanate and amino polymers by a two-step sol-gel and hydrothermal method technique for the fabrication of functional cotton fabric. The prepared TiO2 nanoparticles and the treated cotton fabric were characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), field emission scanning electron microcopy (FE-SEM) photocatalytic and antibacterial measurement. The results indicate the typical characteristic anatase form of the amino-capped TiO2 NPs with an average crystallite size of 14.9 nm. The treated cotton fabrics exhibit excellent antibacterial property and good photocatalytic degradation of methylene blue.
