Abstract A casein derivative (CADP) was synthesized using casein, which is bifunctional containing both –P=O(O-NH4+)2 reactive groups and -P(=O)-O-C- groups, and the durable flame-retardant cotton fabrics were successfully prepared by CADP. The –P=O(O-NH4+)2 reactive groups allowed CADP to be firmly grafted onto cellulose. The –P(=O)-O-C- groups made flame-retardant cotton fabrics more resistant to soaping and improved its durability. The modification by 40% CADP increased the limited oxygen index value (LOI) of cotton fabric from 17.4% to 41.6%, which maintained at 26.4% after 50 cycles of home machine washes. The results of TG, TG-FTIR and SEM indicated that CADP increased the condensed components and decreased the flammable gaseous compounds, resulting the positive effect on char formation of cellulose. The whiteness and tensile strength of cotton fabrics were retained well after modification, and the treated cotton fabrics didn’t have skin irritation.

Durable phosphorus-based flame retardants were applied to twill fabrics con taining cotton and wool to study the effect of wool on the flame retardancy and physical properties of the blend fabrics. The presence of wool in untreated blend fabrics caused burning rates to decrease and oxygen index values to increase as wool content increased in the blends. These effects were also observed in cotton/ wool blends treated with low levels of the Thps-urea-TMM flame retardant, but were less pronounced in fabrics treated at high levels. Thermogravimetric analyses were conducted to study the thermal degradation of the treated and untreated fabrics. The presence of wool in treated blend fabrics did not sig nificantly change strength retention, area shrinkage and wrinkle recovery values in comparison to similarly treated 100% cotton fabrics.

Abstract In this study, intumescent flame retardant coating of polyethylenimine/phytic acid (PEI/PA) with gradient structure was constructed on cotton fabric through facile layer-by-layer (LBL) assembly method. The LOI value of coated cotton fabric reached over 40% indicating excellent flame retardancy. Reasonable controlling the LBL assembly process of PEI/PA coating brought less influence to the physical properties of cotton fabrics. And the coated cotton fabric revealed good flame retardant washing durability. Thermogravimetric analysis results of coated cotton fabrics showed that PEI/PA flame retardant coating changed the thermal decomposition process and promoted char formation revealing the obviously condensed phase flame retardant action. SEM images of char residues revealed that PEI/PA flame retardant coating promoted to form the intumescent flame retardant (IFR) char layer showing obvious IFR action. This research provides novel strategy for the development of high-efficiency flame retardant cotton fabric with good durability and physical properties using simple LBL assembly method.

A new antibacterial with two reactive groups was synthesized from isothiazolin-3-one and characterized by 1H-NMR and ESI-MS. Through the orthogonal experiments the optimal finishing process was got, that was bath ratio 1:20, Na2SO4 20 g/L, NaHCO315 g/L, T1:60°C, T2:70°C, t1:10 min, t2:20 min, t3:30 min (as shown in fig.1). The antibacterial evaluations of treated cotton fabrics showed that the antibacterial rates for Escherichia coli and Staphyloccocus aureus were 95.64% and 97.83% respectively, and 88.13% and 90.05% respectively after 30 washing cycles. The results indicated that the treated fabric had excellent antibacterial performance and washing durability.

In this paper, the application of glow discharge (low pressure) and dielectric barrier discharge (atmospheric) prior to pigment dyeing of cotton fabric was studied. Different parameters of power and time during the process were also discussed. The dyeing effect after different plasma treatment was analyzed by SEM observations and measurements of the K/S value, levelness and color fastness. The results indicated that the particle diameter of pigment affected pigment dyeing, and the K/S value increased as particle diameter decreased. These two plasma treatments could enhance the properties of pigment dyeing with satisfied color fastnesses. Fabrics treated by plasma should be dyed within 2 hours of plasma treatment to ensure optimum results. The power of atmospheric plasma treatments was relatively high without maintaining a vacuum atmosphere, and it could be processed continuously with high efficiency and K/S value.
