Study on Properties of Poly (ethylene terephthalate) Films Treated with Mono-sodium ethylene glycolate
Textile Coloration and Finishing, volume 2, issue 4, 1990, Pages 223~230
This study was carried out with the view of fundamental investigating to improve the tactile and the hygroscopicity of Poly (ethylene terephthalate) (PET) fibers. Mono-sodium ethylene glycolate in ethylene glycol (MSEG-EG) solution was prepared and PET films were treated with it. The following conclusions were obtained. 1. The tensile strength decreased with increasing decomposition ratio while density, crystallinity and crystallite size increased with increasing decomposition ratio when PET films were treated with MSEG-EG solution. 2. Number of carboxyl end groups was increased until 10-20% decomposition ratio when PET films were treated with MSEG-EG solution. However, the decomposition ratio became more than 20%, the number of carboxyl end groups had tendency to decreased. 3. The surface tension of PET films increased for treating with MSEC-EG solution. Hydrogen bonding force and poler force among the components of surface tension increased while dispersion force among those decreased. 4. The moisture region of PET films increased with increasing decomposition ratio when PET films were treated with MSEG-EG solution.
The Carrier Mechanism in the Disperse Dyeing of Poly(ethylene terephthalate)
Textile Coloration and Finishing, volume 2, issue 4, 1990, Pages 231~236
The diffusion coefficient of C.I. Disperse Red 4 in the dyeing of carrier-pretreated poly (ethylene terephthalate) film was Investigated by Sekido's film-rolled method. From the result it was shown that the diffusion coefficient increases exponentially with the content-ration of carrier in the film, and, for the films containing same concentration of carrier, the carrier effect was enhanced with the molar volume of the carriers. The greater carrier effect was accompanied by the decrease in diffusion activation energy and entropy, which shows that the carrier with larger molar volume plasticizes PET film to more extent.
Syntheses of Thermotropic Liquid-Crystalline Copoly(ester amide)s Containing a Flexible Spacer in the Main Chain and Their Structure Interpretation
Textile Coloration and Finishing, volume 2, issue 4, 1990, Pages 237~244
Syntheses and liquid-Crystallinites of thermotropic copoly (ester amide)s were investigated. The three components melt polycondensation of 4,4'-dicarboxy-
-diphenoxyalkane as an A component, 4-4'diacetoxybiphenyl as a B, and p-N-acetoxy-aminobenzoic acid as a C gave the thrmotropic copoly(ester amide)s containing a flexible splacer in the polymer backbone. Diacetylated hydroquinone, methyl hydroquinone, chlorohydroquinone, and phenyl hydroquinone were used as anther B components. A polymer(6BPAB) having 10 mol% of C component and hexamethylene space. showed a typical nematic texture between
. The melting points of the members of this series of polymers increased with decreasing methylene spacer. The polymer structure and mesomorphic nature were examined by solid and solution
spectroscopy, cross polarizing microscopy with a hot stage, and X-ray diffactometry.
Synthesis and Properties of New Side Chain Liquid Crystalline Polymer (I) -Potential of Spiroacetal Moiety as a Mesogen Unit-
Textile Coloration and Finishing, volume 2, issue 4, 1990, Pages 245~250
Copolyspiroacetals were synthesized by interfacial polycondensation from 3, 9-bis(4-hydroxyphenyl)-2, 4, 8, 10-tetraoxaspiroundecane(SAB) and 4, 4'-biphenol(BP) with sebacoyl chloride. These copolymers were soluble in polar solvent such as phenol/tetrachloroethane and sulfuric acid, and exibited good thermal stability. But they did not exhibit thermotropic mesophases. The structures of spiroacetal moiety were observed by computer-aided-modeling that had two types of conformational isomers and not linear and/or not planar conformations.
Flame Retardant Finish of PET fabrics with Bis-(p-bromophenyl) phosphate
Textile Coloration and Finishing, volume 2, issue 4, 1990, Pages 251~256
Bis-(p-bromopheny)phosphate(BBPP) , which serves as flame retardant for PET fabric, was synthesized from phenol and phosphorus oxychloride, and from bromine. In order to investigate the flame retardancy of BBPP, PET fabrics were steam-cured with diluted BBPP solution. The following conclusions were drawn : 1. Flame retardancy of PET fabrics treated with BBPP was excellent, and optimal treating condition was 10% concentration of flame retardant at
2. Clark softness and tensile strength before and after the laundering of PET fabrics treated with flame retardant remained nearly unchanged.
