Polysiloxanes are reviewed for their properties depending on the functionalization of a silicon–oxygen backbone chain. Next, the properties were referred to the requirements that polymers used in plastic/polymer-bonded explosive (PBX)-type explosives must meet. Finally, the current state and prospects for the implementation of polysiloxanes in plastic/polymer-bonded explosive (PBX) formulations are presented.

“…Amino polysiloxane softeners are usually used in textile industry as emulsions. A 10% DPSO emulsion (10 g DPSO emulsified with 5 g fatty alcohol polyoxyethylene ether and 85 g H 2 O) was prepared and its pH was adjusted to about 5.5 by adding HAc during the process of emulsification . Cotton samples were impregnated in a diluted aqueous bath (bath ratio, 10% DPSO emulsion : H 2 O = 1.5 : 100) for about 20 min, padded to wet pick‐up at about 70% on the weight of the dry fibers.…”

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.

“…Six different finishing materials have been used. Three of them are silicon-based, since silicone is an efficient lubricating and soft handle finishing for textile [42][43][44][45]. One is glycerol, which is a sustainable textile fiber softener and is also used for paper coating [34][35][36][37][38][39], another one is wax, as it is a common lubricant used for yarn before knitting [33], and the last one is soap, since it has been used as a finishing material affecting the frictional properties of textiles [41]:…”

Enhanced Knittability of Paper Yarn from the Swedish Forest by Using Textile Finishing Materials

Friction between Swedish paper yarn and needles is a limiting factor that—together with the low yarn flexibility—is hindering the knitting and use of paper yarn as a sustainable textile material. To enhance the knittability, paper yarn was coated with textile finishing materials. The effect of six different textile finishing materials used for textiles processing (three different silicone-based, wax, glycerol, and soap) was evaluated. The treatment evaluation was done by determination of the friction coefficient, tensile testing, and knitting. The friction coefficient was determined by an adaption from the ASTM D3108-07 Standard Test Method for Coefficient of Friction, Yarn to Solid Material. The adaption meant using a specially designed rig, making it possible to simulate the yarn/needle friction during the knitting process and use a tensile testing machine to determine the friction coefficient. Through using the same angle for yarn movement during the knitting process in this adaptation, the effect of the flexibility of paper on the friction coefficient is integrated. Tensile testing was performed using a Tensolab 2512A/2512C electromechanical tensile tester, and knitting tests were performed using a Stoll CMS 822 HP knit and wear flat knitting machine with the E5.2 gauge. The results show that knittability is better for the yarns with lower coefficients of friction and can also be enhanced by spraying with regular water. The tensile properties of the yarn is degraded by the treatments. The wax- and soap-treated yarns were most challenging to knit. The silicone-based and glycerol-treated yarns showed enhanced knittability, where the glycerol treatment results in more protruding fibers compared to the other treatments. All treatments reduced the roughness in the feel of the knit. The results indicate that the Swedish paper yarn can be a future sustainable complement to polyester and cotton.
