Preparation and Properties of UV-Curable Polyurethane Acrylates(I) -Effect of Molecular Weights of Polyol and Diol with Low Molecular Weight into Polymer Chain-
Textile Coloration and Finishing, volume 11, issue 4, 1999, Pages 1~7
Urethane-acrylate propelymers for secondary coating of optical fiber and high - performance material were prepared from the 4,4'-diphenylmethane diisocyanate(MDI), poly(tetramethylene oxide)glycol(PTMG, Mw 650 or 1000), 1,6-hexanediol(HD), 2-hydroxyethyl acrylate(HEA), and dibutyltin dilaurate as a catalyst. UV-Curable polyurethane acrylates were formulated from the urethane-acrylate prepolymers, three types of reactive diluents(DTs) having mono-, di-, and trifunctional-phenoxyethyl acrylate(PEA), hexanediol diacrylate(HDDA), and trimethylolpropane triacrylate(TMPTA), and 1-hydtoxycyclohexyl phenyl ketone(Irgacure 184) as a photoinitiator. The UV-cured films of polyurethane acrylates were obtained by curing using a medium-pressure mercury lamp(U W/cm,
. In this work, the effects of molecular weights of polyol and diol with low molecular weight into polymer chain on mechanical and dynamic mechanical properties of UV-cured polyurethane acrylates were studied. The structure and properties of the films obtained from the UV photopolymerization of urethane-acrylate prepolymer were investigated by FT-IR spectroscopy, dynamic mechanical measurement, tensile testing, and X-ray diffractometry.
A Study on Physical Properties of
Electroconductive Fiber and Wool Blended Fabrics
Textile Coloration and Finishing, volume 11, issue 4, 1999, Pages 8~15
Electroconductive fiber was obtained by acryl fiber treated with
. The Properties and structure of fiber and fabric such as mechanical property, electrical conductivity, fine structure, electrification were investigated. The experimental results are as follows 1) The electrical conductivity of the conducting fiber was greatly increased but fine structure and physical properties were similar to acryl fiber 2) Fabric made by mix spinning with conducting fiber was shown great electrification effect. 3) In the mix spinning with conducting fiber, it was necessary to use different. finishing such as milled finish because stiffness of fabric made by mix spinning with conducting fiber was increased and elastic recovery was decreased. 4) The antimicrobial activity of electroconductive fiber blended wool was effective by Cu component for shake flask test.
A Study on the Tannin Treatment of Silk Fabrics(IV) -Change of Properties in Tannin Treated Fabrics-
Textile Coloration and Finishing, volume 11, issue 4, 1999, Pages 16~23
This study was made to investigate the effects of mimosa tannin and tannic acid on change of properties and photodegradation of silk fabrics according to tannin concentration and irradiation time. The results were as follows. 1. As concentration of tannin increased, thickness, fabric count and stiffness showed no difference. But tensile strength were increased, and elongation were decreased. 2. When concentration of tannin is high, tannin adhered to surface of fabrics. 3. fR absorption bands of untreated silk fabric appeared at
, but those of silk fabric treated with tannic acid appeared at
by treatment of mimosa tannin, respectively. IR absorption bands of photoirradiated silk fabrics appeared at
. But those bands were decreased at the silk fabrics treated with mimosa tannin and tannic acid.
The Dyeability of Indigo Depending on the pH of Reduction Bath
Textile Coloration and Finishing, volume 11, issue 4, 1999, Pages 24~30
Cotton fabric was dyed with indigo at different pHs, dye concentrations, and repeated dyeings. And the K/S value and dye uptake of the dyed materials at those conditions were determined. The decrease of pH during the reduction process of indigo stock solution was observed. As a result the decrease of pH of the dye stock solution depended on the dye concentration and initial pH. The highest K/S value was shown at fabric dyed at pH 11 and the relationship between K/S value and dye uptake depended on initial pH of reduction bath and the slope was lower as the pH increased to 13.
Antimicrobial Activity and Physical Properties of Polyester Fabric Treated with Mixture of Chitosan and Collagen
Textile Coloration and Finishing, volume 11, issue 4, 1999, Pages 31~38
The purpose of this study is to develop multifunctional fabric that has improved antimicrobial activity and reduction rate of gas by treatment of mixture of chito colla and crosslinking material for polyester. The surface morphology of treated PET fabric was studied by scanning electron microscopy(SEM). The properties of the PET fabric, such as antimicrobial activity, whiteness, moisture regain, water absorption and static voltage, and handle were investigated. Antimicrobial activity of treated PET fabric was proved 99%. The surface of treated PET fabric showed harshness and irregularity. The whiteness of treated PET fabric on the baking condition was decreased as time and temperature was increased. The moisure regain of treated PET fabric equally was maintained. Water absorption and static voltage of treated PET fabric were improved. KOSHI of treated PET fabric was increased compared with the untreated PET fabric H/W of treated PET fabric was improved compared with the untreated PET fabric and 2HB/B of treated PET fabric were reduced.
Studies on the Natural Dyes(11) -Dyeing Properties of Cochineal Colors for Wool Fibers-
Textile Coloration and Finishing, volume 11, issue 4, 1999, Pages 39~49
In order to study the properties of cochineal colors, uv-visible spectra of cochineal colors solution, dyeing properties on the wool in several dyeing conditions and thermodynamic parameters were investigated. UV-visible spectra of cochineal colors solution showed hypochromic effect with the lapse of irradiation time but bathochromic shift with decreasing acidity of solution and addition of metallic ions. The concentration of cochineal colors in wool fiber increased with the increase of dyeing temperature, time, and acidity of initial dyebath. The value of apparent diffusion coefficients and standard affinities of dyeing decreased with the increase of dyeing temperature. The standard heats of dyeing
and variation of entropy
increased with the increase of concentration of initial dyebath. The activation energy
were calculated to be 1.399~2.595kcal/mol in condition of 6~1%(o.w.f) dyebath. Wool fabrics were dyed reddish blue by iron sulfate, copper sulfate, aluminum acetate and tannic acid, and red by tin chloride, respectively. Lightfastness of wool fabrics dyed by cochineal colors were increased by mordant treatment, especially copper sulfate and iron sulfate treatment.
Surface Modification of Polyester by UV-irradiation with Oxidizing Agent, and Its Adhesion Property
Textile Coloration and Finishing, volume 11, issue 4, 1999, Pages 50~56
The adhesive properties of polyester cord in rubber matrix were investigated according to the surface modification. The polyester cord was oxidized in sodium hypochlorite solution, and graft-polymerized with acrylic acid under the irradiation with ultraviolet light, and then coated with resorcinol-formaldehyde latex (RFL). The modified surface was checked with scanning electron microscope. The adhesive properties were measured by the full-Out method, and evaluated with regard to the energy of adhesion and the maximum load. The polyester was not oxidized in sodium hypochlorite solution, so the surface was not able to etch to produce the coarse topology. As the concentration of acrylic acid and the reaction time were increased, the graft yields were also increased. It was considered that the acrylic acid would swell the polyester and diffuse easily to the inner side of substrate. The adhesive properties of polyeser to rubber matrix were affected by the surface condition. Namely, the maximum load was almost same, but the energy of adhesion was rather higher In the polyester grafted with acrylic acid than in control one. We concluded that the flexible aliphatic chains of polyacrylic acid situated in the interface of cord and rubber matrix were distributed well the stress and strain all over the filler resulting the high energy of adhesion.
