Incorporation of probiotics on textile surface by sol–gel coating

Development of biocide-based antimicrobial textiles is proving to be a concern for the economy, and more evidently, for the environment and health. On the contrary, probiotic (beneficial bacteria) can replace these traditional biocides in order to overcome the toxicity and resistance problems. This paper elaborates an adapted sol–gel coating process to embed such beneficial spores on the polyester woven surface, and their viability is studied along with the characterization of the physical properties of the coated fabric. The results illustrate successful incorporation of the beneficial spores with an adequate number of living organisms (even after repeated washing cycles), sufficient tensile strength, and good abrasion resistance properties with the opportunity to improve surface wettability maintaining sufficient adhesion between the fibre and the coated layer.

Breathable Fabric

The purpose of this research was to evaluate mechanical properties of a waterproof breathable fabric. A spacer knit with a cotton inner face and a polyester (PET) outer face was coated in order to obtain a waterproof breathable fabric. The applied coat was a mixture of an acrylic paste and a fluorocarbon resin. The treated fabric has undergone several tests to evaluate its mechanical properties. Tensile strength, flexural strength, abrasion resistance, and wrinkle recovery behavior were measured and discussed. After the coating treatment, the fabric was rigidified by 25% and 19% in wale and course directions, respectively. The coated PET face of the spacer fabric was not altered even after 125,000 abrasion cycles. A stiffer fabric was obtained after the coating treatment. However, fabric recovery behavior was ameliorated by 78% and 72% according to wale and course directions, respectively. The coated fabric can be used to produce raincoats and jackets.

The silica sol was applied onto 1, 2, 3, 4-butanetetracarboxylic acid (BTCA) finished cotton fabrics with the attempt to improve the physical properties especially the tensile strength which had a big loss in the previous anti-crease finishing processing. The parameters including the dosage of the coupling agent, the concentration and pH of the sol and the processing methods were studied in detail. Compared to the sample finished with BTCA, 11.8% of the increase in the crease recovery angle and 18.6% of the enhancement in the tensile strength of the cotton fabric also treated with silica sol in the better selected conditions were obtained. The abrasion resistance was also improved.

Coated Layer

Cross-sectional structures of a Re-based diffusion barrier coating on Nb as ultra high temperature material were investigated in order to verify the crystalline structure and composition of the coated layer. Three types coating specimens were prepared by electroplating Re from an aqueous solution on an Nb substrate, followed by Cr-pack cementation in vacuum. The coating process produced three distinct layers; an outer Cr(Re) layer, an intermediate Re-Cr-Nb layer, and an inner Nb(Re) layer. A crystal structure of Cr(Re) and Nb(Re) layers possess similar single crystal bcc structure. The Re-Cr-Nb layer expected to act as a diffusion barrier between the substrate and the outer reservoir layer was comprised of cubic c phase and hexagonal Laves C14 phase. Moreover, several crystal defects such as dislocations and stacking faults as well as voids and cracks are observed in the coating specimen.

Epoxidized natural rubber (ENR) / silica (Si) organic-inorganic composites were prepared by using a sol-gel technique. The choice of ENR (50 mol % epoxidation level), as a matrix was made because of its polar nature which can interact with the silica. The processing of the masterbatch was carried out by sol-gel method at room temperature by dispersing the silica in the rubber and coagulated with steam bath. The performance of the composites was evaluated in this work for the viability of ENR/Si in tyre compounding. Compounding was carried out on a two roll mill, where the additives and curing agents was later mixed. Characterization of these composites was performed by Field Emission Scanning Electron Microscopy (FESEM) and Transmission Electron Microscopy (TEM) for dispersion as well as mechanical testing. Silica was also efficient as primary reinforcing filler in ENR with regard to modulus and tensile strength, resulting on an increase in the stiffness of the rubbers. Improvement in tensile strength over the control crosslinked rubber sample was probably due to synergisms of silica reinforcement and crosslinking of the rubber phase.

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.
