Functional textiles are being developed in order to provide fabrics with new properties and added value. They can be obtained either by using new chemical fibers or by incorporating functional agents to conventional fabrics. Microencapsulation is an effective method to protect these functional agents from reactions with moisture, light, and oxygen. If a fabric is treated with microencapsulated functional agents, higher durability of functionality is expected. This article reports the development and testing of two types of microcapsules containing essential oils for application in cotton fabrics. Microcapsules were obtained by complex coacervation using gelatin and arabic gum or by encapsulation in yeast cells in order to increase the durability of fragrances in textiles. Microcapsule characterization, such as particle size and morphology, was carried out for different oils to polymer ratios and hardening agents to polymer ratios. Padding and coating were tested as application methods. The morphology, durability of the fragrance, and laundering properties of the treated fabrics were investigated. The use of an electronic nose to measure the fragrance release from microcapsules was also evaluated. Gelatin—arabic gum microcapsules increased the durability of the fragrance on the treated fabrics and withstood one wash cycle. Fabrics treated with yeast cell microcapsules presented low fragrance intensity before washing. The fragrance was not detectable after laundering, even though the microcapsules could still be observed on the fabric.

Aroma Finishing of Cotton Fabrics by Means of Microencapsulation Techniques

Physical and mechanical properties of electrospun polyvinyl alcohol (PVA) were related to electrospinning process parameters through fabricated structures, fiber morphology, and diameters. The effects of electrospinning voltage, flow rate and distance between needle tip and collector on tensile strength, strain at maximum load, burst strength, and air permeability were investigated. The results showed that higher applied voltage, lower flow rate, and shorter distance gave higher tensile strength. However, burst strength had critical points during the changes of the above three parameters while all the measured data were in a narrow range. Higher voltage and longer distance caused the lower air permeability. PVA/Laponite® nanocomposites were produced by electrospinning and tensile strength and flammability of electrospun PVA/Laponite® structures were studied. The results indicated that introduction of Laponite® nanoclay to electrospun PVA structure decreased the tensile strength and strain at maximum load. The low orientation of Laponite® nanoclay along the fibers due to the low aspect ratio of Laponite® resulted in lower tensile strength of electrospun PVA webs. The flammability of electrospun webs was characterized by burning rate. Electrospun PVA/Laponite® had slower burning rate than that of pure PVA and thus flame resistance of PVA webs was improved by adding Laponite® nanoclay. The increase in flame retardation is attributed to slower decomposition of PVA/Laponite ® membranes.

This study demonstrated that the changes in functional and comfort properties of knitted cotton fabrics were determined by the knitted structure as well as type and concentration of finishing agent. To improve the comfort properties, one should ensure the smoothness of fabric surface, air permeability, heat transmittance as well as hydrophilicity of the knitted fabrics, by selecting the proper knit structure and/or by applying the proper finish such as bio-finish. Soft-finished fabric samples had lower tendency to shrinkage and lower stiffness unless compared with other finished fabrics. The functional properties of the finished cotton knits, i.e., antibacterial and water repellent, depend to a great extent on the type of finish.

Effect of Knit Structure and Finishing Treatments on Functional and Comfort Properties of Cotton Knitted Fabrics

A novel approach for imparting multi-functional properties, i.e., anti-crease, self-cleaning, UV-protecting as well as anti-bacterial properties onto cotton fabric is described. The multi-functional finished cotton fabric was obtained by pretreatment with the reactant resin, as a crosslinker, along with citric acid or PEG-400, as an additive in presence of MgCl2·6H 2O as a catalyst followed by drying, subsequent loading of TiO 2-nanoparticles and finally curing. Factors affecting the extent of crosslinking as well as deposition and/or fixation of nano-structured titania cluster onto/into treated fabric samples are studied. The modified cotton samples showed an excellent improvement in their functional properties along with a high durability to wash. The possible mechanisms for deposition/fixation of TiO2-nanoparticles onto and/or within the fabric or the finish/fabric matrix as well as its positive impact on fabric resiliency, self-cleaning, UV-protecting, and anti-bacterial functionality are discussed. Surface morphology and surface elemental composition, especially Ti-content, on the loaded films were studied by SEM and EDS, respectively.

Novel Approach for Attaining Cotton Fabric with Multi-Functional Properties

Electroless composite plating of (Ni—P)—ZnO nanoparticles on polyethylene terephthalate fabric was performed in the laboratory. The (Ni—P)— ZnO composite plated fabric was investigated by means of scanning electron microscope, energy dispersive spectroscopy, thermal gravimetric analysis, and X-ray diffraction analysis. The electromagnetic shielding performance and abrasion resistance were also measured. The results show that the onset decomposition temperature of the Ni—P-plated fabric is higher than that of the (Ni—P)—ZnO composite plated fabric, but is lower than that of the original one. The face-centered cube crystal structure of Ni—P deposition is formed due to the incorporation of nano ZnO particles. As compared with the Ni—P-plated fabric, the shielding effectiveness and the abrasion resistance for the (Ni—P)—ZnO composite plated fabric decrease when their percentage weight increases are identical. For the (Ni—P)—ZnO composite plated fabric, the add-ons of nano ZnO particles in the plating solution has little effect on the shielding effectiveness.
