An antibacterial agent (ZPU) was prepared by surface modification of nanoZnO with aliphatic aqueous polyurethane (WPU) and polyacrylates sodium of lower molecular weight (LPAA). Then two kinds of cotton fabrics were dipped in ZPU and finally finished by paking-baking process. ZPU and the finished cotton fabrics were characterized by SEM, TEM and DLS. The antimicrobial properties of the cotton fabrics were investigated. The results indicated that ZnO retained nanosize with little aggregation on the fabric surface. The finished cotton fabrics showed obviously antibacterial activity againstS. aureusandE. coliwith the 24 h antibacterial rate of 99%.

High Degree

Protection against ultraviolet radiation is one of the areas, in which considerable attention is being paid. Application of a wash durable finish on cotton fabric to protect the wearer from these radiations remains a challenge. The harmful effects of UV radiations result in the form of eye disorders, accelerated ageing of skin, DNA damage and cause of cancer. The current study focuses upon the use of TiO2 on cotton fabric to impart UV protection. TiO2 is deposited on cotton fabric using its pre-cursor. Sol-gel method has been used to convert pre-cursor into titanium oxide directly on fabric surface. The deposition was further stabilized on fabric surface by various heat treatments such as curing, hydrothermal and solvothermal treatments. It has been found that the TiO2 remains wash durable with a reasonably high degree of UV protection after hydrothermal and solvothermal treatments. EDX and ICP-MS techniques were used to examine the add-on % of TiO2 on cotton fabrics. The morphology of the TiO2 coated cotton fabric was studied using Field emission scanning electron microscopy. The measurement of UV protection property of the fabric has been carried out using UV-visible spectrophotometer (UV-2000F, Labsphere, USA).

Water Repellence

The properties of the cotton fabric with water-repellence finishing by sol method with the hexadecyltrimethoxysilane as additive were observed. The cotton fabrics were immersed in the prepared sols with double dip and double nip dried at 90°C, annealed at 160°C for 3 min. The water repellence and the physical properties such as gas permeability, bending properties, beetling properties, tensile strength, elongation at break, abrasion resistance, and anti-crease properties of the cotton fabrics were investigated. The results showed that anti-crease and tensile strength were improved. However, the abrasion resistance of the cotton fabrics decreased in some way. Both the bending and beetling properties measurement proved that the handle of the treated cotton fabrics changed stiffness. For the dyed fabrics by the water-repellent finishing, the hue was slightly changed, the deeper color was achieved. There is no adverse effect for treated fabric by water-repellent finishing on the fastness.

Fabric Surface

Sol-gel reaction of two fluoroalkyl end-capped vinyltrimethoxysilane oligomer [RF-(CH2CHSi(OMe)3) n-RF; RF = CF(CF3)OC3F7; n = 2, 3: RF-(VM) n-RF] in the presence of cellulose nanofiber (CNF) under non-catalytic conditions was found to provide the corresponding fluorinated oligomeric silica/CNF composites [RF-(VM-SiO3/2) n-RF/CNF]. The obtained composites were applied to the surface modification of glass to give a good oleophobic/superhydrophobic characteristic on the composite surface due to the fabrication of the roughness architecture. The RF-(VM-SiO3/2) n-RF/CNF composites were also applied to the surface modification of poly(ethylene terephthalate) [PET] fabric swatch, affording a superoleophilic/superhydrophobic characteristic on the modified fabric surface. Modified PET fabric swatch thus obtained was applicable to not only the separation membrane to separate the mixture of oil/water but also the perfect adsorption of oil droplets spread on water interface. In addition, we have prepared the RF-(VM-SiO3/2) n-RF/CNF composites films by casting homogeneous aqueous methanol solutions containing the corresponding composites. Pristine CNF film afforded the superoleophilic property on the surface; however, it was demonstrated that the obtained transparent colorless CNF composite films can supply highly oleophobic characteristic on the surface.
