A novel polysiloxane bearing dodecyl and epoxy side groups (DESO) was synthesized as an intermediate through hydrosilylation of polymethylhydrosiloxane with allyl glycidyl ether and 1-dodecene. Then, dodecyl/piperazine functional polysiloxane (DPSO) was prepared through the reaction of N -aminoethylpiperazine with DESO. The chemical structure of DPSO was characterized with FTIR and 1 H-NMR spectroscopy and its application performance on cotton fabrics was studied. DPSO with dodecyl side groups gifted the treated fabrics with good wettability and whiteness compared with piperazine functional polysiloxane, while with a slightly reduced softness as well as thickening handle. Film morphology, orientation, and performance on cotton substrates of DPSO were investigated by scanning electron microscope, atomic force microscopy, X-ray photoelectron microscope, and so on. Affected by the dodecyl side groups, DPSO formed relatively hydrophilic, macroscopically smooth but actually uneven films with many dodecyl side chain pillars on the treated substrate surfaces. © 2013 Wiley Periodicals, Inc.

A novel kind of impact protective material, named as impact protective micro-gel (IPM), was synthesized via a precipitation copolymerization of a compound containing boron and silanol. Diphenylmethane diisocyanate (MDI) was introduced as the chain extender to enhance its impact protective performance. Its rheological properties and morphology were investigated. Three-dimensional (3D) spacer warp-knitted fabrics were dip-coated with the IPM made with and without use of MDI, and the impact protective performance of 3D finished fabrics was assessed by drop impact tests. The results show that the adjustment of the MDI content can adjust the real cross-linking density of the IPM due to the entanglement of polymer chains, and an appropriate cross-linking density can endow dilatant properties to the IPM samples. The results also show that the impact protective performance of 3D spacer fabrics finished with the IPM can be significantly improved. © 2013 Wiley Periodicals, Inc. J. Appl. Polym.

Traditional superhydrophobic cotton fabrics (SCFs) for oil/water separation were usually fabricated by surface coating with inorganic nanoparticles combined with nonrenewable and nonbiodegradable or even toxic fossil-based chemicals, which would lead to secondary environmental pollution after their lifetime. In this study, we report robust, nanoparticle-free, fluorine-free SFC, which was prepared by acid etching followed by surface coating with epoxidized soybean oil resin (CESO) and subsequent modification with stearic acid (STA). No toxic compound and no nanoparticle were included within the SCF and all the raw materials including cotton fabric, CESO and STA are biodegradable and derived from biological resources. The SCF showed excellent mechanical stability and chemical/environmental resistances. The superhydrophobicity of the SFC survived from mechanical abrasion , tape peeling, ultrasonication , solvent erosion and low/high temperature exposure. The SCF also exhibited good acid/alkali resistance with contact angle over 150° toward different pH water droplets. Moreover, the SCF could efficiently separate oil/water mixtures with efficiency above 97.9% and the superhydrophobicity remained after reusing for at least 10 times. The fully biological-derived SCF with excellent mechanical and chemical resistances exhibit great potential for separation of oil/water mixtures.

The composite after referred to as P(DMDAAC-AGE)/(Ce-ZnO) was prepared via free radical polymerization by polymer including quaternary ammonium salt and epoxy group which grafted onto the surface of Ce-ZnO. ZnO nanorods, Ce-ZnO nanorods, P(DMDAAC-AGE), P(DMDAAC-AGE)/ZnO composites, P(DMDAAC-AGE)/(Ce-ZnO) composites and commercial antimicrobials were respectively treated on the cotton fabrics and their biological properties were investigated. There is a synergistic effect between Ce-ZnO and N + from the polymer in the fabric treated with P(DMDAAC-AGE)/(Ce-ZnO) composite so that it had a better antibacterial activity than pure polymer and pure Ce-ZnO. The antimicrobial rate of fabric treated with P(DMDAAC-AGE)/(Ce-ZnO) composite could reach up to 96%. And in order to investigate the durable ability, the fabric was washed multiple times to simulate the daily use washing. The result showed that the fabric still gave a superior antibacterial performance after 11 cycles (the equivalent of 55 times house laundering). Simultaneously, the differences in the amount of P(DMDAAC-AGE)/(Ce-ZnO) composite deposited on the fibers after washing were also investigated.

Reactive disperse dyes with mono- and bi-acyl fluoride reactive groups have been synthesized using a simple and convenient method. The structures of these dyes have been defined by 1 H, 13 C and 19 F NMR. The cotton dyeing in supercritical carbon dioxide (Sc CO 2 ) with dyeing temperature varying from 60 °C to 120 °C and time between 1 h and 3 h and with the concentration of 0.5% owf (on weight of fabric) have been studied. Significant improvement of the color fastness of washing and rubbing has been observed owing to the covalent bond formed between the reactive group of dyes and the functional group of cotton fibers . Besides, the dyed fabrics possess favorable fastness properties , indicating the achievement of lower-temperature dyeing of cotton in Sc CO 2 . Additionally, the end products meet the garment dyeing standards as well. A mechanism of dyeing process is tentatively speculated meanwhile.
