“…In previous studies (Monllor et al, 2010) padding procedure was tested in order to obtain the optimum conditions for the padding process. As a result conclusions showed that in order to to reach up to 20 washing cycles keeping not only microcapsules on textile surface but their active function, 60 g/L of microcapsules and 10 g/L of acrylic binder was the optimum recipe.…”

“…All the samples were thermally dried in a scale pin stenter at 110º C for 10 min in WTC BINDER 030. Previously, it has been demonstrated that this temperature was high enough to polymerise the binder without evaporating the fragrance (Monllor et al, 2010). Table 1 …”

“…We can observe a wide variety of active products such as fragrances [Li et al 2006;Nelson, 2001;Monllor et al 2007;Monllor et al, 2010], phase change materials (Fan et al, 2004;Hawlader et al 2003;Xiao_Zheng et al 2003;Zhang et al 2004), dyes (Chang et al, 2003;Sawada et al, 2005), antimicrobial agents (Gisbert et al, 2009;Madene et al, 2006;Nelson, 2002;Wang et al, 2005) etc., which makes microcapsules an attractive field to study and of course patent applications have been increasing. Microcapsule shell is also varied (Madene et al, 2006;Nelson, 2002;Wang et al, 2005), but when it is based on oil materials, amino polymer resins such as melamine formaldehyde or urea formaldehyde have recently gained much attention due to the possibility of increasing oil shelf life and targeted delivery (Long et al, 2009).…”

Microcapsules are widely used, being one of the fields which has increased their consumption the textile one. They can be applied to textiles using different methods such as, padding, bath exhaustion, spraying and foaming. Although the most extended industrial application is by padding commercial brands also suggest bath exhaustion as a possible procedure. In the research reported herein, bath exhaustion treatments are compared to padding. XPS (Photoelectronic spectroscopy of X-Rays) technique showed it was a suitable method to detect microcapsules presence on fabric surface. Results reported that high concentrations were required to obtain similar behaviours to those of padding. Moreover, we suggested reusing bath exhaustion baths, in order to minimise the loss of so much product in wastewater. We concluded it was not possible because microcapsules deflate when get in touch with water for a period of time, and what is more interesting, microcapsules preparation must be done just immediately before they are going to be used, so as to avoid microcapsules deflation due to contact with water.

“…The samples treated with an acrylic binder were cured at 110ºC. Previously, it had been demonstrated that this temperature was high enough to polymerise the binder (Monllor et al 2010). The sample treated with BTCA were cured at 160ºC, temperature necessary to achieve the crosslinking and not to change the colour of the fibre considerably (Franklin et al 1972;Socrates G 1997) …”

Monllorpérez, P.; Gisbert Paya, J.; Díaz-García, P.; I. Montava; Montava Seguí, IJ. (2015). A comparison between acrilic resin and butanetetracarcoxylic acid used to bind TiO2 nanoparticles to cotton fabrics. Cellulose. 22 (2) ABSTRACTIn order to apply finishing particles onto fabrics, several methods such as, padding, bath exhaustion, spraying and foaming can be used. In this research, spray treatment is compared to padding when applying TiO 2 nanoparticles onto textile. Cotton fabrics´ surfaces were observed by scanning electron microscopy (SEM) and characterized by Fourier Transformed Infra Red (FT-IR) spectroscopy and energy dispersive using X-Ray (EDX). EDX technique showed that it was a suitable method to detect the presence of Ti particles on the fabric surface. We confirm that the fabric treated by padding procedure contained a higher quantity of Ti particles than the one treated by spraying. On the other hand, we compared two different auxiliary products to bind the particles onto the fibers, an acrylic resin and the polycarboxilic acid 1,2,3,4-butanetetracarboxylic acid (BTCA) in the presence of sodium hypophosphite (SHP). We used EDX to evaluate the effectiveness of both binders after washing . We improved the presence of TiO 2 particles on the fibers when using an acrylic resin, and observed that when BTCA, is used to fix the particles, there was no increase in the quantity of titanium on the fabric after 5 washing cycles compared to the sample without binder treatement.

“…This process happens when a fluid flows in laminar state and breaks into droplets of a same size through an overlapped vibration. Then these drops transform into a gel in an ionic solution, resulting in the encapsulation of the active ingredient (Core) with a polymer (Shell) [27] [28].…”

The aim of this work was to develop a functional biodegradable nonwoven with antimicrobial microcapsules maintaining the stability and biodegradability of the nonwoven for use in agriculture applications. The nonwoven was obtained using hemp fibers by Wetlaid technology. Microcapsules were prepared by co-extrusion/gelling method with alginate as shell and oregano oil as core material. The microcapsules were developed to protect and control release of oregano oil. Microcapsules were incorporated on the nonwoven by coating method using a natural polymer as a graft material. After incorporating microcapsules, the nonwoven was subjected to several tests in order to determinate the microcapsules fixation and their functionality. The nonwovens were characterized for their antimicrobial activity against different kinds of bacteria and fungi. Nonwoven loaded with microcapsules was found to show good antimicrobial activity in comparison with nonwoven that was not loaded with microcapsules.
