“…Layer-by-layer self-assembly coating provides a promising candidate for the surface modification of fibers, which can maintain the main structure and repair defects on the fiber surface [22]. Therefore, layer-by-layer self-assembly coating attracts increasing attention among researchers due to its feasibility, easy accessibility, good repeatability and preparation of multilayer films by alternately depositing charged substrates in oppositely charged polyelectrolyte solutions [23,24,25]. This method now has been used to modify cotton fibers [26,27,28,29], PBO fibers [30] and aramid fibers [22].…”

In this work, the layer-by-layer self-assembly technology was used to modify aramid fibers (AFs) to improve the interfacial adhesion to epoxy matrix. By virtue of the facile layer-by-layer self-assembly technique, poly(l-3,4-Dihydroxyphenylalanine) (l-PDOPA) was successfully coated on the surface of AFs, leading to the formation of AFs with controllable layers (nL-AF). Then, a hydroxyl functionalized silane coupling agent (KH550) was grafted on the surface of l-PDOPA coated AFs. The properties such as microstructure and surface morphology of AFs before and after modification were characterized by FTIR, XPS and FE-SEM. The results confirmed that l-PDOPA and KH550 were successfully introduced into the surface of AFs by electrostatic adsorption. The interfacial properties of AFs reinforced epoxy resin composites before and after coating were characterized by interfacial shear strength (IFSS), interlaminar shear strength (ILSS) and FE-SEM, and the results show that the interfacial adhesion properties of the modified fiber/epoxy resin composites were greatly improved.

“…Cotton fabrics dyed with brightening agents [31], reactive dyes and acid dyes [32] have been studied in the literature via the LbL method. In some other studies, the LbL process is used as a pretreatment before dyeing to prevent dye aggregation and to increase dye uptake for cotton [33] and polyester fibers [24].…”

Large amounts of water, synthetic dyestuffs and chemicals are used in the wet processes of textile finishing, and at the end of these processes, liquors containing chemical substances create a waste load. For this reason, it is of great importance to develop new wet-finishing processes that use less water, dyestuffs and chemicals. For this purpose, the layer-by-layer deposition method (LbL) was used in this research as an environmentally friendly, sustainable method that can be used in wet-finishing processes to minimize chemical, water and energy consumption. The dyeing and functional finishing of cotton fabrics were carried out in one process by the LbL method. Cotton fabrics were pre-treated with a commercial cationic dye fixation agent and cationic charges were produced on the fabric surfaces. Reactive and direct dyestuff groups were used in the dyeing process of cotton fabrics and fluorocarbon was used in the functional finishing process. Eight and 12 dye/fluorocarbon layered structures were obtained by LbL deposition using a laboratory-type padder. Cotton fabrics were dyed and finished with the same dyes and fluorocarbon via the padding method and both samples were compared. The washing, rubbing and light color fastness properties, color strength and color difference of the dyed samples were tested. Tensile strength, air permeability, SEM graphs, contact angle, water and oil repellency analyses were performed for the treated fabrics.

“…Moreover, with the changes in the surrounding environment (e.g., pH or temperature), the functional chemicals would be released controllably, generating stimulus-responsive functional textile. 38 Pourjavadi et al prepared polyisopropylacrylamide (PNIPAAm)/chitosan (PNCS) nano hydrogels containing cinnamon oil to modify cotton fabrics, yielding functional textile with temperatureresponsive antibacterial property. 39 Wang et al studied the cellulose/silica composite microcapsules used as nishing agents yielding waterborne multifunctional fabrics with the controllable release properties of lavender essential oil.…”
