“…The formulation used for the treatment was 80 g / L of BTCA and 40 g / L of NaH2PO2, after drying at 85ºC, have been cured at 160º C, these parameters being the values that define the optimal formulation that has resulted from the studies carried out in order to avoid yellowing [4]. The first difference observed during the application process is the…”

“…Said chemical treatment involves the use of agents of crosslinking, mainly formulated by reagents such as the dimethyloldroxylethylenurea (DMDHEU) which are considerably effective but they can generate carcinogenic formaldehyde [1], but these products have such disadvantages such as reduction of mechanical properties [2], degradation of fiber and especially the release of toxic and irritating vapors from formaldehyde [3] or colour degradation due to yellowing [4]. In order to attack this problem, polycarboxylic acids have been used as alternative to reagents with formaldehyde, being the subject of study of many research papers currently [5][6][7][8].…”

Cellulosic fibres, like cotton, are characterized by good properties. However, during their use and maintenance, textiles made with these fibres show high capacity of shrinkage, wrinkling and little wrinkle recovery. In order to solve this behaviour, cotton fabrics are treated applying crosslinkers agents in combination with an appropriate catalyst. In this study, 1, 2, 3, 4 butanetetracarboxylic acid (BTCA) and a catalyser, sodium hypophosphite NaH2PO2 . H2O (SHP) were used to treat two cotton fabrics in order to get easy care properties. To study the influence of the weight per square meter of the fabrics, weave fabrics with 110 and 210 g/m2 were treated by padding system using 80 g/L of BTCA and 40 g/L of SHP. Once the treatment was applied, the samples were dried at 80ºC and cured at 160ºC, these conditions are necessary to carry out the cross-linking reaction between cellulose and BTCA. Results show that fabric with less weight per square meter has an increase of 20% of free carboxylic groups, however the fabric of higher weight presents an increase of 120%. To calculate the increase in free carboxylic groups, it has been taken into account the number of those groups from the same fabric before the treatment. As a conclusion, we can confirm that modification of properties are achieved more effectively when the treatment of polycarboxylic acids is performed on cellulosic fabrics with higher content of oxycellulose groups and this factor influence is higher than the g/m 2 .

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.
