Low-temperature Dyeing of Silk Fabrics using a Glyoxal/Hydrogen peroxide Redox System
Textile Coloration and Finishing, volume 6, issue 1, 1994, Pages 1~7
A low-temperature dyeing system for silk fabrics based on a redox system has been investigated. Some factors affecting dyeing of silk fabrics with levelling acid dyes in the absence and presence of certain redox system were investigated under different conditions. The variables studied were; type and concentration of redox system, dyeing conditions, i. e. temperature and time, dye concentration, material-to-liquor ration(LR) and colour fastness. The colour strength(K/S value) is outstandingly higher in the presence than in the absence of redox system. A comparison between the colour strength values of such dyeings abtained the three redox system would call for the following order ; Glyoxal/hydrogen peroxide>thiourea/hydrogen peroxide>glucose/hydrgen peroxide> nothing. In the presence of redox system, free radicals are supposed to be formed in both the fiber and the dye and the interaction between these free radicals bring about covalent fixation beside the usual electrostatic bonds, hydrogen bonds and Van der Waals forces.
One Bath Dyeing of Silk/Synthetic Fibre Blends(IV) - Adsorption Behavior of Acid Dyes/Disperse Dyes on Silk/Acetate -
Textile Coloration and Finishing, volume 6, issue 1, 1994, Pages 8~18
In one bath dyeing system of silk/cellulose acetate fiber blend fabric with acid /disperse dyes, adsorption behavior of acid dyes and disperse dyes on silk and cellulose acetate fabrics were examined. In the dyeing of cellulose acetate with C. I. Disperse Red 19(Red 19) and C. I. Disperse Red 60(Red 60) at 8
, dye uptake with Red 19 was higher than that with Red 60. When the silk/cellulose acetate dyed with Red 19 and Red 60 at 10
, dye uptake on cellulose acetate was influenced by affinity of the dye to the silk fabric dyed together. When the silk/cellulose acetate dyed with Blue 80/Red 19 and Blue 80/Red 60 at 10
, color of cellulose acetate dyed with Red 19 and Red 60 was not influenced by Blue 80 but silk dyed with Blue 80 was influenced by Red 19 and Red 60. Interrelation of K/S value and Munsell value was scarcely any but showed the change tendency of K/S value.
A Study on Tannin Treatment of Silk Fabrics(I) -Condensed Tannin-
Textile Coloration and Finishing, volume 6, issue 1, 1994, Pages 19~27
Mimosa and Quebracho are, in general, tanned with leather skin, finished silk fabrics according to temperature, treatment time, tannin concetration, pH, and studies that relation between tannin weighting and various factors. This makes fundamental study on characteristic of tannin treated fabrics. and the results are as fallows : 1. λ
was found at 278.5nm for Mimosa. 279.5nm for Quebracho. Also a stability was good in standing time and heating. 2. The higher tannin treatment temprature was, the better tannin weighting effect was. But they were slightly decreased at over 8
, and K/S was slowly increased. 3. As tannin treatment time increased, tannin weighting effect increased but they were decreased at over 8
, 90min. 4. As tannin concentration increased, tannin weighting was increased. 5. In tannin weighting effect according to various pH conditions, the it's best range of pH were 3.5~5.5 of Mimosa, 2.5~3.5 of Quebracho.o.
Syntheses and Absorption Spectra of Polymethine Cyanine Dyes Such as Squarylium and Croconium Dyes
Textile Coloration and Finishing, volume 6, issue 1, 1994, Pages 28~32
The synthesis and absorption spectra of squarvlium(SQ) dyes and croconium(CR) dyes were .studied. Absorption spectra of SQ dye in various solvents exhibited a negative solvatochrornism. Thus, it was suggested that the structure of SQ dye may be a highly polar structure. The λ
of CR dyes undergoes a bathochromic shift of about 100nm compared with the corresponding SQ dyes. This shift can be calculated by the Pariser-Parr-Pople molecular orbital method. From the PPP MO calculation results, we found that SQ dye and CR dye have a almost same Highest Occupied Molecular Orbital(HOMO) level(SQ : -8.0eV, CR : -8.09eV). On the other hand, energy levels of Lowest Unoccupied Molecular Orbital(LUMO) of SQ and CR dyes are -4.09eV and -4.13eV respectively. Thus, replacement of five membered ring by four membered ring in SQ dye causes a large bathochromic shift.t.
Accelerating Effect of Neutral Salts on Alkaline Hydrolysis of Poly(ethylene terephthalate) (I) - Cationic Effect -
Textile Coloration and Finishing, volume 6, issue 1, 1994, Pages 33~43
In the present work, to clarify the mechanism of the neutral salt effect on the alkaline hydrolysis of PET, many salts with different cations like LiCl, NaCl, KCl, CsCl were added to the aqueous alkaline solutions. Then PET was hydrolyzed with aqueous solutions of many salts in alkali metal hydroxides under various conditions. Some conclusions obtained from the experimental results were summarized as follows. The reaction rate of the alkaline hydrolysis of PET was increased by the addition of neutral salts and In k was increased nearly linearly with the square root of ionic strength of reaction medium. This fact suggested that the ionic strength effect by Debye-Huckel and Bronsted theory was exerted on the reaction. The specific salt effect was also observed. The reaction rate was increased with the increase in the electrophilicity of cations of neutral salts, i. e., in the order of
. It was considered that the reaction rate was increased in the order of C
. because the lowering effect of the cations on the negative charge of PET surface was increased with the electrophilicity of cations. It was thought that
was increased because the cations of neutral salts decreased the negative charge of PET surface. It, however, was inferred from the increase in
S＊ and the decrease in the
G＊ that the cations of neutral salts associated with PET increased the collision frequency between carbonyl carbon and OH- ion and then accelerated the reaction rate.te.

Textile Coloration and Finishing, volume 6, issue 1, 1994, Pages 49~53
The transparent coloration of glasses has been successfully achieved by coated glass surface with squarylium dye by the sol-gel colored coating method. Treatment of sol-gel colored coating layer with HCI(g) greatly decreases the absorbance at λ
, that increases exposure to
(g) and the reversible color-colorless responce was extremely rapid.d.

Textile Coloration and Finishing, volume 6, issue 1, 1994, Pages 54~61
Acrylamidomethylated cellulose(AMC) was prepared by a reaction of N-methy-lolacrylamide(NMA) in the presence of acid catalyst, and pendent C=C double bonds are created on cellulose. Using the pendant double bonds as a site for Michael addition, a number of modified cellulose could be readily prepared. When AMC is treated in an aqueous solution containing sodium dihydrogen phospate and methylamine, the chemical structure of cellulose is represented as follow ; Cell-O-
-NHMe. Therefore in this paper, dyeing properties of modified cellulose for the acid dye were investigated.

Textile Coloration and Finishing, volume 6, issue 1, 1994, Pages 62~70
Silk fibroin was dissolved in 9.3 M LiBr aqueous solution at 4
for 1 hour. The dissolved silk fibroin was regenerated by casting the dialyzed solution into the membrane. The freshly prepared silk fibroin membrane was soluble in water and was. mainly consisted of random coil conformation. By the treatments in saturated water vapor at 3
and in 75% ethanolic aqueous solution (V/V), the insoluble membranes were obtained and the structure and morphology of those were investigated for the structure by means of X-ray diffraction analysis, infrared spectroscopy, thermal analysis. Rheovibron and scanning electron micrograph. Silk II type crystals were obtained by treating amorphous silk fibroin membrane in the random coil conformtion with 75% ethanol solution(V/V). Crystallization to silk II type crystals occured even after a few minutes, and a large number of silk II type crystals were formed after 30 mins. On the other and, the membrane treated in saturated water vapor was composed of the mixtures of silk I and silk II type crystals. A large number of silk I and silk II type crystals were formed after 24 hours. The micro brownian motion in the amorphous regions of silk fibroin membrane started at about 175~185
dispersion appeared at about 20
in the amorphous membrane, and at about 22
in the crystalline membrane. The crystallization of random coil conformation to silkII type crystals occured at about 215
. The surface, bottom and cross-section of the membranes were observed by scanning electrom microscope. Fine forms alike spherulites appeared at the surface of crystalline membrane.
