“…4a)-b)), DPTMS/Cotton showed a lower T 5% than cotton, because some phosphoruscontaining groups were decomposed into phosphorus-containing free radicals, phosphoric acid or polyphosphates when heated (Ding et al, 2022). On the one hand, it absorbed a lot of heat, on the other hand, it promoted the dehydration of cellulose to form a carbon layer and inhibited the formation of Lglucose (Tian et al, 2023). At the same time, phosphorus free radicals reacted with the combustion products of cotton to made cotton phosphorylated.…”

A phosphorus containing polysiloxane flame retardant and antibacterial agent has been synthesized and applied to cotton fabrics. A treatment method has been implemented to achieve the dual function of flame retardant and antibacterial on cotton fabrics, Achieve two things at one stroke. This flame retardant method can effectively avoid the problem of formaldehyde release from fabrics treated with phosphorus containing flame retardants. Amino silicone oil and p-bromobenzaldehyde are used to synthesize intermediate products, phosphite, 5,5-dimethylhydantoin, and phosphite to obtain halogenated amine precursors (DPTMS). The VFT and LOI results indicate that this additive can effectively improve the flame retardancy of fabrics. Thermogravimetric analysis shows that the residual carbon content of DPTMS/Cotton can reach 9.1% and 24.7% under air and nitrogen conditions, respectively, indicating that DPTMS can effectively improve the thermal stability of cotton fabrics. The cone calorimetry test showed that the total heat release of DPTMS/Cotton was significantly reduced by 49.8% compared to that of Cotton. After being heated, polysiloxane provides a more solid carbon layer, which has a suffocating effect on the flame. The results of antibacterial test are surprising, and the antibacterial rate of DPTMS/Cotton against E. coli and S. aureus can reach more than 99%.

We have developed a Tf 2 O-mediated approach for the direct amination of either P(O)−OH or P(O)−H reagents with a variety of aliphatic or aromatic amines. Without the requirement of precious metals and toxic reagents, this protocol provides an alternative route to various phosphinamides and phosphoramides. The reaction proceeds under simple and mild conditions and can be effectively scaled up with similar efficiency.

Terylene/cotton (TC) fabrics are widely used in the textile industry because of their superior softness and durability. In addition, its high combustibility leads to a great safety hazard, and the droplet phenomenon during combustion is particularly serious. 9‐oxa‐10‐phospha‐9,10‐dihydrophenanthrene 10‐oxide (DOPO) and its derivatives are frequently used as eco‐friendly flame retardants in large quantities in substrates. It would be difficult to apply to the surface of the fabric, and the addition of large amounts would lead to a decrease in the mechanical properties. Therefore, it is necessary to design a strategy for graft‐functionalized flame retardants that can be applied to surfaces. Here, this study reported a washing‐fastness flame‐retardant coating (DOPO‐p) synthesized from DOPO and p‐hydroxybenzaldehyde (p‐HBA), coatings with a low weight growth and high flame‐retardant efficiency are prepared by the strategy of dissolving with organic solvents. Water and dry‐cleaning tests showed excellent washing fastness of TC fabrics. In the limiting oxygen index (LOI) test, the finished fabric achieved a LOI value of 22.9%. In the cone calorimetry test, the peak of heat release rate of the finished fabric is decreased by 27% and CO2 release is reduced by 29% when the coating weight growth was only 3.3 wt%.
