Analysis of Process Characteristics by Single Yarn Production in Ring Spinning
Lee, Choon-Gil ; Oh, Bong-Hyo ; Park, Sung-Diuk ;
Textile Coloration and Finishing, volume 9, issue 5, 1997, Pages 1~9
In the single yarn spinning process by the ring spinning system, the finer the fineness of yarn and the lower the twist coefficient, the lower the breaking strength and breaking elongation. The change of yarn specific volume to yarn number agreed with Peirce's formula in the range of Ne 50 to 70, but above that range the values of the experiment are higher than that of the formula. The change of diameter of yarn to the reciprocal of the square root of yarn number agreed with Peirce's formula in the range of under 0.14, but above that value the values of the experiment are higher than that of the formula. In breaking strength variation according to twist constant of single yarn, as the twist coefficient increased, breaking strength increased. At 5.8∼6.0 of twist coefficient the maximum breaking strength was shown, but above that value breaking strength decreased. Breaking elongation also showed a similar tendency. But at 6.0∼6.5 of twist coefficient the maximum breaking elongation was shown. Also spinning tension increased as twist coefficient increased. Twist coefficient, breaking strength and breaking elongation according to the number of coils stayed almost the same. Yarn spinning tension according to the number of coils at the maximum of diameter was the lowest value. The speed of the traveller at the maximum of diameter was the highest value.

Cho, Kyung Rae ;
Textile Coloration and Finishing, volume 9, issue 5, 1997, Pages 10~18
In order to study the properties of safflower yellow colors, thermodynamic parameters and dyeing properties on the silk in several dyeing conditions were investigated. The uv-visible spectra of safflower yellow colors in several solvents show hypsochromic shift with the polarity of solvent but bathochromic shift with increasing acidity of solution. The apparent diffusion coefficients and standard affinities of dyeing increased with the increase of dyeing temperature. The standard heat of dyeing(
), entropy change(
) and activation energy(
) were calculated to be - 1.144kcal/mol, -7.498(5
)cal/molㆍdeg and 0.123kcal/mol, respectively. The concentration of safflower yellow colors in the silk fiber increased with dyeing temperature, time, concentration of colors and acidity of initial dyebath. Silk fabrics were dyed bright yellow by pre-mordanting with tin chloride. Lightfastness of silk fabrics pre-mordanted by tin chloride was not excellent.

Textile Coloration and Finishing, volume 9, issue 5, 1997, Pages 19~29
A natural colorant was extracted from Clove using methanol. The dyeabilities and fastness of silk fabrics dyed with Clove extract were investigated. The results obtained were as follows; 1. The colorant extracted with methanol was higher in concentration than that with boiling water and was represented high reproducibility. 2. The optimum dyeing temperature and dyeing time were 6
and 60min, respectively. 3. The color depths were observed to be decreased as follows; pre-mordant > after-mordant repeat dyeing > after-mordant > simultaneous-mordant 4. Clove extract dyed brownish black on the Fe-mordanted silk. In case of the other mordants, silk fabrics dyed yellow. 5. The dyed silks had poor light-fastness but good wet-fastness.

Textile Coloration and Finishing, volume 9, issue 5, 1997, Pages 30~41
A purpose of this research is to prove unknown relation -ship between finish bath pH and crosslinking. In pursuit of these goals, we have treated 100% cotton broad cloth with PTCA and BTCA at different pH values. They were used with H
, catalysts to produce nonformaldehyde fabrics finishes. Treatments were applied to all cotton fabrics using a parletry-cure process. For the fully understood on the relationship of finish bath pH effect and cotton cellulose esterification, the relative concentrations of chemical species were calculated from ionization constants. The effect of pH on the cotton cellulose ester was investigated using Fourier transform infrared spectra, the surface area measurement by BET method and wrinkle recovery analysis. Results of differential FT-IR spectra and their relative concentration analysis were compared with those of catalyst treated controls. FT-IR and wrinkle recovery data indicated that the esterfication by polycarboxylic acids is pridependent. A similar phenomenon also occurred when a phosphate or hypophosphite was used. Therefore, it is necessary to choose the optimum pH range of a finishing bath in order to achieve the most effective esterification.

Park, Seong-Woo ; Lee, Suk young ; Cho, In-Sul ; Cho, Hwan ;
Textile Coloration and Finishing, volume 9, issue 5, 1997, Pages 42~51
The purpose of this article is to investigate the effect of
low temperature plasma treatment oft chitosan treatment of polyester fabrics. Moisture regain, static charge, crease resistance and reduction ratio of the treated fabric were measured. The results of this study were as follows: The add-on ratio and. the moisture regain of polyester fabrics treated with chitosan after treated by plasma(CP PET) were higher than those of polyester fabrics treated with only chitosan(C PET). The static charge of polyester fabrics decreased greatly with increasing the concentration of chitosan. A durability for laundering of CP PET was higher than those of C PET. The crease resistance of polyester fabrics decreased with ihcreasing the concentration of chitosan continuously. CP PET had higher decreasing rate and better durability than C PET. It showed that chitosan-treated polyester fabrics had over 90% reduction ratio after 10 times of laundering, and CP PET had better reduction ratio than C PET.

Abstract Polyurethanes have been designed and fabricated into membranes with unique separation properties. Moreover, polyurethane microcapsules also have been reported actively as controlled release materials for their excellent blood compatibility, tensile strength and permeability. In this study, polyurethane microcapsules were synthesized by interfacial polymerization in an aqueous poly(ethylene glycol) dispersion of toluene diisocyanate in perfume oil using poly(vinyl alcohol) as the stabilizing agent. The effect of a few important process conditions on the average particle size and distributions, morphologies, and thermal properties to design microcapsules for the sustained release system was investigated.

Polyurethane microcapsules were synthesized by interfacial polymerization in an aqueous poly(ethylene glycol) dispersion with ethylenediamine as chain extender of toluene diisocyanate in perfume oil using poly(vinyl alcohol) as the stabilizing agent. The effect of chemical structure on the average particle size and distributions, morphologies, and thermal properties to design microcapsules for the sustained release system was investigated. It came to be known that polyurethane microcapsules with ethylene diamine as chain extender had a rounder, more permeable and controlled release membranes. And the release test of polyurethane microcapsules with different soft segment content was done to certify the effect of long methylene chain. According to the higher molecular weight of polyether polyol, the release rate of microencapsulated disperse dye molecular was faster.

Textile Coloration and Finishing, volume 9, issue 5, 1997, Pages 75~81
o-Aminobenzene sulfone-N-ethylanilide, the diazo component of C.I. Acid Red 57, is currently being diazotised by the use of nitrosylsulphuric acid because of its high molecular weight and weak basicity. However, this method has many problems such as complicated manufacturing process and discharge of large volume of strong acidic effluent. In this study, the possibility of replacing nitrosylsulphuric acid method by direct method, which is simpler and produces less effluent, has been checked and the optimum process condition was studied. The effect of HCl concentration, the amount of sodium nitrite and particle size of diazo component on diazotisation yield was investigated. The optimum pH condition for coupling reaction was also evaluated.

Modified polypropylene was made of melt blending using thermostable-filler and polypropylene polymers. Modified PP were characterized for the purpose of improving a thermal-property of PP polymer with the composition of 5wt %, 10wt % of thermostable-filler. The structure and thermal-property were determined from IR, DSC, TGA, and SEM instruments. From the results of this study, it found the following facts. Firstly, it was found that the modified PP was mixed with PP and thermostable-filler qualitativly. Secondaty, thermal property of modified PP was improved steadily according to increase of ratio of thermostable-filler.
