Cotton fabrics modified with Si@ hyperbranched poly(amidoamine): their salt-free dyeing properties and thermal behaviors

Phosphorous Containing poly(amidoamine-organosilicon) (P@PAMAMOS) Flame Retardants: Synthesis and Sol-gel Application on Cotton Fabrics

“…In compared with untreated cotton ber, cotton fabrics grafted with P@PAMAMOS have a stronger peak at 3500-3000 cm -1 , which is contradicts the previous conclusion (Brancatelli et al 2011). This phenomenon can be explained that the overlapping peaks of the stretching vibration of amino group and the cellulose hydrogen bonded (Zhang et al 2021), indicating cotton fabrics have been graft by P@PAMAMOS. The adsorption peak at 1649 cm -1 is due to the stretching vibration of -CONH-, the characteristic peaks at 1566 cm -1 and 1430 cm -1 ascribed of the primary amine(-NH-) appears (Wang et al 2014;Zhang et al 2007;Zhang et al 2021).…”

The stretching vibration of P=O was shown in 1114 cm -1 (Zhang et al 2020;Liu et al 2020;Jia et al 2017), in compared with other modi ed cotton fabrics, the adsorption peak of the B 10 treated cotton was stronger, which is explained that the B 10 treated cotton has the highest phosphonium content.…”

“…The peak at 1466 cm -1 indicated the existence of the methylene group bending vibration (Zhang et al 2021); the absorptions at 1200 cm -1 was caused from stretching vibration of P=O (Zhang et al 2020;Liu et al 2020;Jia et al 2017). The appearance of characteristic peak at 1114 cm -1 was assigned to P-O-C bonds (Liu et al 2020;Wang and Cai 1989;Zheng et al 2016); The characteristic absorptions peaks at 1040 and 694cm -1 coincide with Si-O-Si bending vibration (Brancatelli et al 2011;Zhang et al 2021;Zhang et al 2020;Liu et al 2020).…”

“…3, the peaks at 3418 cm -1 belongs to the stretching vibration of amine groups in P@PAMAMOS (Wang et al 2014;Zhang et al 2007;Zhang et al 2021), 2850-2950 cm -1 were attributed to the stretching vibration of methyl and methylene(C-H) in P@PAMAMOS (Wang et al 2014), the strong absorptions at 1653 cm -1 were characteristic of the carbonyl stretching vibration of in amide bonds(-CONH-), and bending vibration of amine groups (N-H) appears at 1561 cm -1 (Wang et al 2014;Zhang et al 2007;Zhang et al 2021). The peak at 1466 cm -1 indicated the existence of the methylene group bending vibration (Zhang et al 2021); the absorptions at 1200 cm -1 was caused from stretching vibration of P=O (Zhang et al 2020;Liu et al 2020;Jia et al 2017).

Insights into coloration enhancement of mercerized cotton fabric on reactive dye digital inkjet printing

“…6,7 Cotton is well known as one of the most popular agricultural renewable resources because of its excellent hand feel, moisture absorption and air permeability. [8][9][10][11] However, in the process of digital inkjet printing, the imaging quality and dye utilization were poor due to the unique structure of the fabric and the cotton bre's higher crystallinity. 12 To eliminate the adverse effects caused by cotton properties, several researchers have tried various approaches to overcome this problem.…”
