Single-faced flame resistance of cotton fabrics modifiedviamist copolymerization

Abstract

Cotton fabrics with single-faced flame resistance are successfully fabricated through a simple mist copolymerization process using pentabromobenzyl acrylate (PBBA) as the functional monomer. The comonomers are methyl acrylate (MA), which can react with the hydroxyl groups of cellulose by transesterification, and divinyl benzene (DVB), a cross-linker. SEM images indicate that a very thin copolymer layer (the thickness is about 200 nm) was formed on the cotton fiber surface and the flame resistance tests show that the modified fabrics have an improved flammability with longer time to ignition (TTI), lower peak heat release rate (PHRR), lower total heat release (THR), and lower average mass loss rate (AMLR), when compared to the original cotton fabric. The modification also results in good wearing durability because the flame-retardant coating was covalently linked to the cotton fabric surface by many ester groups. Moreover, desired cotton characteristics such as tensile strength, water absorbency, vapor permeability and flexibility are mostly retained because the mist method gives a single-faced modification of the cotton fabrics.

High antibacterial durability of silver nanoparticles anchored on cotton fiber surfaces by 4‐vinylpyridine polymers synthesized via a “grafting through” strategy

“…Therefore, resent research hotspots of textile fabric functional finishing focus on additional functions like waterproof, vapor transmissibility, [2][3][4] self-cleaning, 5,6 antibacterial, [7][8][9] UV protection, 10,11 and flame retardant. 12,13 Interactions among the microporous structure of cotton fabric, the body temperature (temperature) of the wearer, the moisture (water) emitted by the human body, and the metabolites (nutrition) of the skin provide cotton textiles with a suitable growth environment for microorganisms, allowing them to be a suitable hotbed for the breeding and reproduction of microorganisms such as bacteria and fungi, which may causes problems to human health. 14 Thus, attention to human health has stimulated people's interest in developing efficient antibacterial CF.…”

Photodegradation Kinetics and Solvent Effect of New Brominated Flame Retardants (NBFRS) in Liquid Medium

“…In recent years, with the mass production and use of NBFRs, they have been widely present in various environmental media, even human blood [ 8 , 9 ]. Hexabromobenzene (HBB), pentabromotoluene (PBT), pentabromobenzyl acrylateare (PBBA) and pentabromoethylbenzene (PBEB) are considered as four important currently used NBFRs with respect to production and consumption all over the world [ 10 , 11 , 12 , 13 , 14 , 15 , 16 ]. The concentration levels of HBB, PBEB and PBT in the atmospheric environment has shown an upward trend [ 17 ].…”

Excellent binding effect ofl-methionine for immobilizing silver nanoparticles onto cotton fabrics to improve the antibacterial durability against washing

“…Cotton fabric has suitable exibility, water absorptivity, and air permeability for wearable textiles; therefore its wear comfortability has been well-received by customers. [1][2][3] To extend its market share, various efforts have been made to endow cotton textiles with additional functions, [4][5][6] and such exploration has gradually concentrated on a few areas, for example, antibacterial effects, 7,8 UV-protection, 9,10 hydrophobic coating, 11,12 ame retardance, [13][14][15] and wear-resistance. 16 Among these functions, the antibacterial effect has received more signicant attention because the bacterial problem of cotton textiles oen seriously troubles users.…”
