A Study on the Mechanical Properties to the Weight Reduction Rate of PET Fabrics(I)
Textile Coloration and Finishing, volume 10, issue 5, 1998, Pages 1~12
This study surveys the mechanical properties such as bending and shear properties to the weight reduction rate of PET fabrics. For this purpose, 12 kinds of satin and 18 kinds of plain weave fabrics are prepared with change of the physical properties of weft yarn(T.P.M., density, and denier) The weight reduction rate was 0％, 12％, 25％, and 30％. Bending rigidity and hysteresis, shear rigidity and hysteresis were measured and discussed with theoretical values in relation with weft twist, yarn linear density, weft fabric density and weave structures.
A Study on the Dyeing Property of EVA Blended Polypropylene Fiber
Textile Coloration and Finishing, volume 10, issue 5, 1998, Pages 13~18
Polypropylene-ethylene/vinyl acetate copolymer (PP-EVA) blends were prepared by mechanical blending using relatively semi-crystaline ethylene-vinyl acetate copolymer and polypropylene. In order to obtain dyeable PP fiber, PP-EVA blends were prepared using below 10wt.％ of EVA and formed a filament by the melt spinning method. The resultant fibers had tensile strengh of 2∼3g/d, elongation of 330∼600%, initial modulus of 22∼46g/d, and exhibited markedly improved dyeing property.
A Study on the Preparation and Properties of Cellulose-EVOH Fibers
Textile Coloration and Finishing, volume 10, issue 5, 1998, Pages 19~23
In this study, Cellulose-Poly(Ethylene-Co-Vinyl Alcohol) (EVOH) fibers from MMNO(N-me-thylmorpholine-N-oxide) /water/cellulose/EVOH were prepared according to changes of EVOH content(wt％), which is main factors to dry-jet wet spinning. The mechanical properties and morphology of produced fibers were investigated. The resultant fibers had tensile strength of 3.7∼4.5g/d, elongation of 3.3∼7.5% and exhibited lower density than the density of pure cellulose fiber.
Durable Press Performance and Water Repellency of Cotton/Polyester Fabrics Finished by BMDHEU/Fluorochemicals
Textile Coloration and Finishing, volume 10, issue 5, 1998, Pages 24~31
The effects of DMDHEU alone and DMDHEU/Fluorochemical(FC) combined treatment on the physical properties of 75％/25％ cotton/polyester(CP) blended fabrics were investigated. FC water repellent and DMDHEU durable press finishes were applied in combination to CP fabrics to provide good water repellency as well as great durable press(DP) performance. The physical properties of the fabrics were evaluated by wrinkle recovery angle(WRA), DP performance, contact angle, demand wettability, and water repellency. The durable press/water repellent finished(DP/WR) CP fabrics show considerably improved WRA and DP performance. The DP/WR finishes do not change the water contact angie of polyester fibers significantly, while the DP finishes increase it. Both DP and DP/WR finishes increase the contact angle of cotton fibers. The water uptake amount increases in the following order : DP/WR cotton, DP/WR CP＜DP cotton, DP CP ＜ Control CP, Control cotton. The water uptake amount increases in the following order DP/WR CP, DP/WR cotton ＜DP cotton ＜DP CP＜Control CP, Control cotton. Considerable improvements for water repellency are imparted to the CP fabrics treated with DP/WR, and the level of improvement is not significantly different from that of the DP/WR cotton fabrics. These results lead to the conclusion that DP/YVR treatments a single pad bath on CP are effective finishes for improving both DP performance and water repellency.
Ring Opening Polymerization of Lactone Using Polyethers
Textile Coloration and Finishing, volume 10, issue 5, 1998, Pages 32~38
Glycolides were polymerized by PPG or Pluronic(PN) to give A-B-A block copolyesters consisting of polyglycolide(A) and polypropylene glycol(B) or polyglycolide(A) and PN (B). Lactones were easily copolymerized with polyethers by ester interchange reaction even in the absence of catalyst. It is because PPG and PN are telechelic polyethers having hydroxy groups on their both ends. When the feed ratio of PPG(M
=4,000) and PN(M
=11,500) were over 5 and 10 wt% .elative to glycolide, respectively, the polymerization of glycolide took place from the terminus hydroxy groups of PPG or PN to produce the desired A-B-A block copolymers in high yields. The molecular weights of the copolymers, which estimated from the monomer conversions and the feed ratios of PPG and PN, could be controlled by changing the kind of terminus hydroxy of polyether and the feed molar ratio of PPG and PN. PN.
A Study on Alkali-Treatment of Polyester/silk Union Cloth
Textile Coloration and Finishing, volume 10, issue 5, 1998, Pages 39~47
The purpose of this study was to investigate the effect of alkali treatment on EG solution of polyester/silk union cloth(P/S cloth) . Tensile strength, moisture regain, crease resistance, and reduction ratio of the treated P/S cloth were measured. The results of this study were as follows ： 1) The weight loss of P/S cloth treated with EG solution was three times higher than those of P/S cloth treated with
. The weight loss of P/S cloth was increased greatly with increasing concentration of NaOH, temperature, and time. Favorable weight reduction of treating condition could be obtained when lower concentration of NaOH was used with longer time. 2) If it was added
on EG solution, weight loss of polyester increased, while those of silk decreased. In addition, decreasing ratio of tensile strength warp direction (polyester) was lower, while those of weft direction(silk) was higher. 3) Moisture regain of P/S cloth treated with EG solution increased with weight loss up to 10% . Crease resistance of P/S cloth was the highest at weight loss of 10~15%.
The Bathochromic Effect of Polyester Fabric Treated with Low Refractive Compounds
Textile Coloration and Finishing, volume 10, issue 5, 1998, Pages 48~55
Polyester fabric is widely used in textile material though it has some problems such as low colour value, high refractive ratio(1.62) and etc. In order to give Z-black colour of polyester fabric, this study has selected several disperse dyes by measuring of absorbance, dyed in their optimum conditions and treated with 4 kinds of low refractive compounds such as silicone, fluorine, urethane and silicone-fluorine mixed compounds. The bathochromic effect of treated PET fabric evaluated as lightness(L) change by uv-visible spectrophotometer. This study also investigated that the effect of used bathochromic agents on the washing and lightfastness of treated PET fabric.
The Effect of Acetophenone on the Dyeing of Silk
Textile Coloration and Finishing, volume 10, issue 5, 1998, Pages 56~62
In the prior study, the dyeing behaviors of Milling Cyanine 5R on silk fiber in aqueous dyeing liquor including small amount of organic compounds were investigated. The most effective compound was acetophenone which increased dye uptake as well as dyeing rate. In this study, the role of the acetophenone in dyeing of silk with Milling Cyanine 5R was studied. By addition of acetophenone into the dye solution, the molar absorptivity of Milling Cyanine 5R increased, and the wavelength of maximum absorption was shifted to longer wavelength, namely bathochromic shifted. This shows that the acetophenone prevents the dye to aggregate, and increases the number of monomeric dye molecule relative to the dye solution without acetophenone. This fact was also confirmed by the increase of the permeation rate of the dye through cellulose semipermeable membrane from the dye solution including the acetophenone. From these results, the acetophenone acts as a prohibitor of dye aggregation, increases the number of monomeric dye molecules even at relatively low temperature, and makes the dyes penetrate into the fiber easier.
