“…This is believed to be associated with the molecular structures of the polysiloxanes, their orientations, and the characteristic film morphology as well as the properties of the polysiloxane films on fiber surfaces [3,8,9,12,13]. The best way to study the film morphology of a polysiloxane on a fiber surface is to directly observe the treated fiber or fabric with SEM [8,12].…”

A water-soluble polysiloxane (PE-PUVSi) bearing functional benzophenone derivative and hydrophilic polyether side groups was successfully synthesized by hydrosilylation of polyhydromethylsiloxane (PHMS) with 2-hydroxy-4-(β-allyloxy-γ-hydroxy)propyloxy benzophenone (MUV-O) and allyl polyoxyethylenepolyoxypropylene ether (F6). The chemical structure, film morphology, and performance of the synthesized polysiloxane were investigated and characterized by spectral analysis, atomic force microscope (AFM), Kawabata evaluation system (KES), and other instruments. Experiment results indicate that PE-PUVSi had an intensive UV-absorbing capacity at wavelengths of 243.6, 289.2, and 325.0 nm. It formed a hydrophilic polysiloxane film on both the fiber and the silicon wafer surface. On the wafer surface, PE-PUVSi actually showed non-homogeneous and phase-separated microscopic film morphology. In addition, PE-PUVSi could provide a bulky softness, good wettability, and antistatic property for the treated fabric and make the treated cotton fabric show a low UV transmittance at the wavelengths between 270 and 330 nm.

“…This operation was developed to remove surface contaminants (due to processing and handling), and minimize the wrinkling while drying. 17 The APSs were dissolved in isopropanol (0.05 wt %) and applied to the cellulose substrates by dip coating. Then the samples were dried at 100 C for 10 min, cured at 120 C for 2 min and finally conditioned at 20 C and 65% relative humidity.…”

Amino polysiloxanes (APSs) with different amino values and amino types were synthesized and applied to cotton fabrics. Softening and smoothening properties of the fabrics treated with APSs were investigated and evaluated by measuring wrinkle recovery angles and friction coefficients, and the morphological features of the APSs adsorbed onto cellulose substrate films were characterized by atomic force microscope (AFM). The results indicate that the amino values and amino types of the APSs have a significant impact on the softening and smoothening properties of the fabrics. APSs with relatively high amino values exhibit superior smoothening property, while APSs with moderate amino values exhibit excellent softening property. Compared to the traditional softener N-b-aminoethyl-c-aminopropyl polydimethylsiloxane (APS-1), the new amino type softeners c-piperazinylpropyl polydimethylsiloxane (APS-2) and N-c'-dimethylaminopropyl-c-aminopropyl polydimethylsiloxane (APS-3) gave better fabric performance, whereas aminopropyl polydimethylsiloxane (APS-4) and N-cyclohexyl-c-aminopropyl polydimethylsiloxane (APS-5) gave unsatisfactory fabric performance.

“…An et al [8] have investigated the film morphology and orientation of amino silicone on cotton fiber by FESEM and XPS, and proposed that the orientation of amino silicone on cotton fiber substrate is in such an approach that the hydrophobic Si-CH 3 groups project outward into air, while Si-O dipole bonds as well as the polar amino groups point to the interface between amino silicone and cellulose. Burrell et al [9] examined the thin layers of amino silicones on cellulose surface by angle-dependent XPS to study the orientation of the amino endgroup relative to the main polymer chain, and proposed the model with the endgroups adsorbed onto the cellulose interface and the polymer chains forming loops that extend toward the air. But amino silicones with different amino values provide different softening benefits and properties of textiles, which indicate that their film morphology and roughness are diverse [10][11][12].…”
