The cotton, and Bast fiber fabrics were dyed with reactive dye and direct dye, and the change of the tensile strengh and the elongation were measured. And the loss of the tensile strength and elongation and color fastness with Ultra Violet radiation (carbon are Fade O-meter. 100hrs) were measured, and the following results were obtained. (1) For the cotton fabric, the tensile strength was increased but for other fabrics were decreased by dyeing. (2) The elongation of all samples were decreased by dying. (3) Little change in the rate of tensile strength and elongation loss with U.V radiation of the reactive dyed fabric was better than direct dyed one.

Effect of pH and temperature on shirnkage of greyknits(Slip) and effects of scouring conditions on shrinkage, reflectance, handle and reactive dyeing properties of cotton warp knits were studied. The result are as follows. In solution at room temperature and pH 7∼13. The maximum area shrinkage was about 20% pH has no effect on area shrinkage but on linear shrinkage. Temperature has no effect on area shrinkage of grey knits. in mixed solution of sodium hydroxide and soda ash. The decrease of concentration ratio of soda ash made the reflectance decrease and the softness increase. The maximum equilibrium absorption obtained at pH8, but the fixation was obtained at pH10. Scouring conditions has a small effect on the rate of fixation but a large effect on the rate of absorption.

張瑛燾 건국대학교 1980 學術誌 Vol.24 No.2

Fully scoured habutae silk fabric were dyed making the use of various types of reactive dyes and dyeing receipts recommended by the in manufactures and then the dyed habutae were put on to the usual fastness tests. The obtained results were; 1.Among the dyes studied the brands of procion MX, Drimalank, Drimalen X, and Renazol had higher absorption and fixation properties accompanied by unlevel dyeing phenomena. 2.When dyeing with procion MX dyes, the neutral absorption alkaline fixation process had better dye fixation than the simultaneous process of absorption and fixation under alkaline condition. 3.All the studied reactive dyes indicated excellent fastness to light and wash, due to covalent bonding of the dye-fiber system combined with the specially controlled dye chromogene structure.

The over-preparation of blood for elective surgery causes some problems such as returning of blood, inefficient task and loss of reagents. In recent blood transfusion practice, there has been changing patterns of blood use in elective surgery as various side effects of transfusion have become known and operation techniques are developed. This study was performed to evaluate the optimal utilization of blood for various elective and/or emergency surgery. We surveyed the quantity of blood transmitted to wards, returned to blood bank, and the number of crossmatching test done for the elective surgery of the patients at the D. University Hospital, the tertiary teaching hospital from August 1, 2001 to October 31, 2001. Crossmatched to transfusion ratio (C/T ratio) was calculated, in which C means the unit of accomplished crossmatching test and T means the unit of transfused blood component. The unit of transfused blood was analysed in terms of issuing time, sex, age, clinical department, and blood component type. The usage of bloods for the emergency surgery was also analyzed. In our study, C/T ratio was highest on Monday (1.54) and Tuesday (1.53), and higher in female patients(1.54) than in male patients (1.32). No significant relationship was observed between age groups. Among clinical departments, thoracic and cardiovascular surgery showed the highest C/T ratio (1.54). From above results, we could be sure that the management of transfusion practice was relatively appropriate in recent years, although the entire introduction of type and screen (T&S) method was desirable. If the T&S method is performed, the C/T ratio would be almost 1.00 and it would also relieve the duty of blood bank.

In this study, the flame retardancy, physical properties, and the thermal behavior, phosphorus and nitrogen contents of cotton fabrics finished with incorporating some additive was investigated. Breaking strength was almost constant for all treated fabrics, but tearing strength was decreased as the conc. of treating solution was increased, and the fabric treated with 40% and 35% solution lost 36% of it's original tearing strength. Dry flex abrasion strength was remarkably decreased and sample treated with 40%, solution retained 38.5% of it's original strength. It shows that if the fabric treated with above 35% solution of THPC-Urea (mole ratio 1:1), it is to be passed DOC FF 3∼71 flame test. Generally, the monsanto's crease resistance of all treated fabrics was increased. TGA analysis shows that the temperature of initial weight loss of treated fabrics were lower than that of untreated fabric by about 80-100℃ and major weight loss temperature was also lower about 40℃. The weight of the residues left at 500℃ for flameretardant finished fabrics were much larger. Phosphorus and nitrogen content of treated fabric was increased as the conc. of treating solution, and decreased against number of washes. It phosphorus content was above 3% or nitrogen content was above 2.7%, it is to be passed DOC FF 3-71 flame test.

絹織物의 增量과 染色에 관한 硏究

張瑛燾 건국대학교 1977 學術誌 Vol.21 No.2

Scoured habutae silk fabrics were weighted with Tin-compound, and then reactive, cathionic, and acid dyes were applied on the weighted samples, in order to obtain the action of carious dyeing proceses on the weighting. The author could obtain the following 3 results. 1.When reactive dyes are applied on the scoured and weighted silk fabrics by the alkaline dyeing method, weighted silk fabrics increase their weight dueing to the dye amount combined with the sick and the activities of salts added in the dyeing proceses. 2.Cathionic dyes decrease the weights of Tin-weighted silk fabrics. The caution is explained as the action of the acid added as dyeing assistants. 3.Acid dyes also reduce the weights of weighted silk fabrics during their general acid dyeing process. The caution is enplaned as the same as the case of cathionic dye for dyeing weighted silk fabrics.

반응성 염료-Locust Bean Gum 날염호의 반응성에 관한 연구

張瑛燾 건국대학교 1985 學術誌 Vol.29 No.2

The formation of chemical bonds between Locust bean gum and reactive dye in the printing paste was studied by means of Thin Layer Chromatography (T.L.C). Various printing pastes of different compositions were prepared and applied to T.L.C palates on three different conditions: (1) immediately after preparation, (2) after 24 hour standing at room temperature and (3) after 24 hour standing at room temperature followed by 15 minutes refluxing at 80℃. The Results obtained are: i) In the printing pasts of Locust bean gum, the dye of reactive (procion H type) almost does not form chemical bond even though it was heated in the presence of alkali for a certain period. ii) The dye of reactive(procion M type) easily forms chemical bond only in the presence of alkali without heating and keeping. iii) At a constant alkali concentration, as increasing the content of dye, amount of reactive dye(procion dye) reacted with Locust bean gum increases, but the ratio of reacted dye to the total dye decreases. iv) In making mixd printing pastes of reactive(procion H type) if the alkali content and ratio of mixing are controlled appropriately, Locust bean gum can be used with sodium alginate.
