“…The embedding of fragrant microcapsules on textiles imparts new properties and added value to products, with multiple applications such as clothing, decorative textiles, and non-implantable medical textiles [5]. Application of microcapsules to textiles can be done by padding, coating, immersion, spraying, and printing [6][7][8][9][10]. The results of research reports comparing different methods of applying fragrant microcapsules to textiles (i.e., printing, padding, exhaustion) show that the padding technique is more suitable than others because the yield is higher, fewer chemicals are required, and it can be done at room temperature [6,9,10].…”

A major problem associated with the application of microcapsules on textiles is the loss of textile functionality after a few wash cycles, even if binders are used in the application.…”

Application of Fragrance Microcapsules onto Cotton Fabric after Treatment with Oxygen and Nitrogen Plasma

et al. 2021

Cotton fabric was exposed to low-pressure capacitively coupled plasma to enhance the adsorption and adhesion of fragrance microcapsules (FCM). Two plasma-forming gases, namely oxygen (O2) and nitrogen (N2), were investigated. The untreated and plasma-treated samples were investigated for their morphological changes by scanning electron microscopy (SEM), mechanical properties (breaking force, elongation, and flexural rigidity), and wicking properties. The cotton samples were functionalized with FCM and the effect of plasma pretreatment on the adsorption and adhesion of FCM was evaluated using SEM, air permeability, fragrance intensity of unwashed and washed cotton fabrics, and Fourier transform infrared spectroscopy (FTIR). The results show that the plasma containing either of the two gases increased the wicking of the cotton fabric and that the O2 plasma caused a slight etching of the fibers, which increased the tensile strength of the cotton fabric. Both plasma gases caused changes that allowed higher adsorption of FCM. However, the adhesion of FCM was higher on the cotton treated with N2 plasma, as evidenced by a strong fragrance of the functionalized fabric after repeated washing.

“…So far, there are several traditional approaches for fixation of essence directly on the textiles to endow the textiles with functional fragrance via immersing, − padding, coating, − printing, microwave, , ultrasound ultraviolet, , etc. However, drawbacks of poor combination fastness, fast aroma volatilization, and failure to achieve the effect of long-lasting fragrances impede the development of these aromatic textiles.…”

Control-released aromatic-nanocapsules/cotton fabrics with good wash durability and long-lasting fragrance release capability have been fabricated without adhesives via electrostatic-adsorption and in situ immobilization methods. Quaternary ammonium cationic treatment provided the cotton fabrics with a positive charge surface to adsorb negatively charged aromatic nanocapsules with the core material of lavender essence and the wall material of epichlorohydrin modified cyclodextrin uniformly and abundantly. Afterward, in situ immobilization endowed aromatic nanocapsules with the capability of fast “growing” on the surface of the cationic cotton fibers evenly and firmly due to the mechanism of alkali solution inside–outside diffusion and penetration throughout fibers. The fragrance of the developed fabrics could be released continuously after being placed for 120 days. After five wash cycles, the maximal percentage of remaining essence still reached 91.19%, which was 4.7 times that of the unimmobilized aromatic fabrics. In the process of preparation, the absence of adhesives reduces environmental pollution, and the aromatic nanocapsules solution is recyclable, which are conducive to industrial sustainability. Electrostatic-adsorption/in situ immobilization provides a facile and green strategy for preparing nanocomposite materials with potential applications in the field of aromatic medical care textiles, functional aromatic household, clothing products, advanced functional materials, etc.

“…Microencapsulation technique is an efficient method to protect active compounds especially fragrant components such as essences and natural oils from being destroyed by heat, light, and high temperature in their utilizations . Nowadays, embedding fragrant micro‐/nanocapsules into textiles to fabricate aromatic textiles becomes more and more popular in textile finishing industry, and there are several approaches for fixation of fragrant micro‐/nanocapsules on the textiles: immersing, padding, coating, spraying, and printing . Parts of the systems mentioned above need to undergo a relatively high temperature which may cause the breakage of micro‐/nanocapsules during the aromatic finishing processes; thus, microwave curing and ultraviolet (UV) curing are used to alternate the thermal process helping to solve these problems.…”

Aromatic reservation is one of the key evaluation index of textiles which be finished with fragrant micro‐/nanocapsules, and some researches discover that when the fragrant micro‐/nanocapsules penetrating into the spacing of textiles, the resulting aromatic textiles own much better carrying capability of micro‐/nanocapsules. Based on these phenomena, hence in our research, the matching up between pore sizes of cotton textile and sizes of fragrant micro‐/nanocapsules is investigated systematically in order to reveal the size effect on the durability of fragrant micro‐/nanocapsules in cotton textile. Firstly, the pore sizes of cotton textile are analyzed by three different techniques: 3D X‐ray microscopy (Micro‐CT), nitrogen adsorption/desorption method (BET), and mercury intrusion porosimetry (MIP) technique. Based on the pore sizes obtained from MIP technique, citronella oil/chitosan micro‐/nanocapsules with three corresponding sizes are prepared and then applied on cotton textiles through vacuum impregnation process. The pore sizes of cotton textile measured by MIP technique decrease from before finishing to after finishing with nanocapsules, which states that nanocapsules are entrapped inside the pores of cotton textile. Finally, the washing durability of aromatic cotton textile is evaluated by headspace–solid‐phase microextraction (HS‐SPME) technique combining with GC‐MS which can keep the fragrant micro‐/nanocapsules unbroken to simulate the “real” sniffing environment. The results show that aromatic cotton textile treated with nanocapsules possesses much better washing durability, which is met up with the results of pore size measurements: More nanocapsules are penetrating into the spacing of cotton textile fibers even the pores in fibers.
