The fabrics with electromagnetic interference (EMI) have been used in various fields. However, most studies related to the EMI fabrics focused on the improvement of the final electromagnetic shielding effectiveness (EM SE) by adjusting the preparation parameters while the breathability of the EMI fabrics was affected and the visible surficial patterns on the EMI fabric was limited. In this work, the two samples based on the Song Brocade structure were fabricated with surficial visible pattern ‘卐’. One was fabricated with silver-plated polyamide (Ag-PA) yarns and the silk yarns, the another with polyester (PET) yarns and the silk yarns. The weaving structure of the two samples were investigated by scanning electronic microscopy (SEM) and laser optical microscopy (LOM). The resistance against the EM radiation near field communication (NFC) and the ultraviolet (UV) light was also evaluated. Besides, the surface resistance, the air permeability and the water evaporation rate were investigated. The results revealed that the ‘卐’ appeared successfully on the surface of the two samples with stable weaving structure. The Ag-PA yarn-incorporated Song Brocade fabric had the EMI shielding effectiveness value around 50 dB, which was supported by the low surface resistance less than 40 Ω. The excellent NFC shielding of the Ag-PA yarn-incorporated Song Brocade was also found. The ultraviolet protection factor (UPF) value of the Ag-PA yarn-incorporated Song Brocade fabric was higher than 190. The air permeability and the evaporation rate of the Ag-PA yarn-incorporated Song Brocade fabric was higher than 99 mm/s, and 1.4 g/h, respectively. As a result, the Ag-PA yarn-incorporated Song Brocade fabrics were proposed for both the personal and the industrial scale utilization.

“…Functional textiles initially focused only on individual value-adding properties. However, recent research has targeted combinations of multiple properties and effects, leading to new multifunctional smart textiles with three or more functionalities in one product, such as simultaneous aromatic, antimicrobial, UV-protective and superhydrophobic effects [86][87][88][89].…”

Microencapsulation for Functional Textile Coatings with Emphasis on Biodegradability—A Systematic Review

2021

View full text Add to dashboard Cite

The review provides an overview of research findings on microencapsulation for functional textile coatings. Methods for the preparation of microcapsules in textiles include in situ and interfacial polymerization, simple and complex coacervation, molecular inclusion and solvent evaporation from emulsions. Binders play a crucial role in coating formulations. Acrylic and polyurethane binders are commonly used in textile finishing, while organic acids and catalysts can be used for chemical grafting as crosslinkers between microcapsules and cotton fibres. Most of the conventional coating processes can be used for microcapsule-containing coatings, provided that the properties of the microcapsules are appropriate. There are standardised test methods available to evaluate the characteristics and washfastness of coated textiles. Among the functional textiles, the field of environmentally friendly biodegradable textiles with microcapsules is still at an early stage of development. So far, some physicochemical and physical microencapsulation methods using natural polymers or biodegradable synthetic polymers have been applied to produce environmentally friendly antimicrobial, anti-inflammatory or fragranced textiles. Standardised test methods for evaluating the biodegradability of textile materials are available. The stability of biodegradable microcapsules and the durability of coatings during the use and care of textiles still present several challenges that offer many opportunities for further research.

“…However, the coating acts as the outermost layer of the substrates, and it is easy to be covered and contaminated by dust or other contaminants, which will restrict the functions of coatings. Over the past few years, superhydrophobic coatings with water-repellent property has aroused huge attention due to their extensive applications (e.g., self-cleaning, ,, oil–water separation, , anticorrosive, − as well as functional textiles − ). Considerable superhydrophobic surfaces were fabricated by integrating a micro- or nanoscale hierarchical structure with low-surface-energy materials. − Thus, by introducing the superhydrophobic ability into thermal insulation coatings, the coatings can be endowed with multifunctions, and they can be allowed to adapt to the outdoor environment.…”

“…Pickering emulsion polymerization, replacing conventional emulsifiers with solid nanoparticles as emulsifiers, could serve as a novel strategy for preparing multiple compartment microcapsules. − With the Pickering particles and the oil phase of the Pickering emulsifier as different loading spaces, the produced microcapsules are capable of separating different microcarriers into two different containers. Furthermore, with inorganic particles (TiO 2 , SiO 2 , ZnO, and CaCO 3 ) as Pickering emulsifiers, the prepared organic/inorganic composite microcapsules can achieve specific functions for their own characteristics. ,− …”

By designing and preparing multifunctional materials exhibiting self-healing ability, problems related to their durability outdoors can be solved. This study, inspired by the self-healing mechanism of natural creatures, successfully prepared a dual self-healing multifunctional coating using temperature stimuli-responsive multicompartment microcapsules. Phase change materials (PCMs) were employed to load multicompartment microcapsules that were produced through Pickering emulsion polymerization by applying hydrophobic materials encapsulated by titanium dioxide (TiO2) nanocapsules as Pickering emulsifiers. The multifunctional coating produced using microcapsules and self-healing waterborne polyurethane (WPU) exhibited thermal insulation and antireflection properties, which was attributed to the application of PCMs and TiO2, and it also achieved remarkable superhydrophobicity. Moreover, this coating exhibited the intrinsic and superficial dual self-healing ability, which was attributed to the release of hydrophobic materials from microcapsules and the self-healing ability of WPU. This study can be referenced to guide the fabrication of high-performance self-healing materials, and it can contribute to the long-term use of multifunctional coatings.
