A Study on the Alkali Hydrolysis of PET fabrics with Ultrasonic Application(II)- Surface Porosity and Oligomer Analysis -
Textile Coloration and Finishing, volume 14, issue 6, 2002, Pages 305~312
In order to give a silk-like touch to PET fabrics, the PET fabrics were treated with NaOH alkaline solution in various conditions. In alkaline treatment, the liquor flow type pilot weight reduction apparatus with magnetostrictive ultrasonic transducer was used for the study. The effects of ultrasonic application, treatment time and temperature at NaOH 4% and 6"A solution on the decomposition rate of PET fabrics. From the results of the decomposition rate of PET fabrics, the qualitative and quantitative analysis of oligomer after decomposition of PET fabrics carried out by the HPLC. On the other hand, the surface pore characteristics of decomposition PET fabrics measured by porosimetery. The pore characteristics on the surface of treated PET fiber depended on the decomposition rate and did not depend on the ultrasonic cavitation. The pore diameter of alkaline untreated PET fiber were 15A and those of treated PET fibers were 5~6
at the maximum pore volume. The average pore sizes of fiber before and after treatment were 141 h and 160h, respectively. Total amount of oligomer of the untreated PET fibers were 1.70wt% and 67.7% of total oligomer occupied with PET cyclic trimer and PET cyclic tetramer. Total amount of oligomer of fiber with 26.9% and 48.0% of weight loss without ultrasonic application were 1.78wt% and 1.79wt%, respectively. Also total amount oligomer of fibers which were reduced 27.7% and 48.2% of weight loss with ultrasonic application were 1.74wt%. This result showed that the removal rate of oligomer in the process of alkaline hydrolysis with ultrasonic higher than that of without ultrasonic application.tion.
Physical properties of chitosan added on acrylic acid grafted cotton fabrics
Textile Coloration and Finishing, volume 14, issue 6, 2002, Pages 313~318
Chitosan is known to be an excellent biocompatible natural polymer. Recently, with a growing interest of health and environment, chitosan which is good in no harmful effect on human body and environment, has been watched as the finish treatment of hygiene and pleasantness. The purpose of this study is to develop multi functional fabrics by chitosan added on acrylic acid grafted cotton fabrics. Therefore physical properties such as moisture regain, air permeability, whiteness, static voltage and tensile strength of chitosan added on acrylic acid grafted cotton fabrics were investigated. The results are as follows ; According to increased chitosan's concentration, grafting yield was decreased. Therefore thickness of film by treated chitosan added on acrylic acid grafted cotton fabric became thin. FT R spectra of chitosan add on acrylic acid grafted cotton fabric clearly showed peaks of COOH and
, Moisture regain, static voltage of chitosan add on acrylic acid grafted cotton fabrics were increased than control. Air permeability, whiteness and tensile strength were decreased than control.
Dyeing Properties of Nylon 6 Ultramicrofiber
Textile Coloration and Finishing, volume 14, issue 6, 2002, Pages 319~327
Nylon 6 ultramicrofiber(UMF, monodenier 0.074d) and regular staple fiber(monodenier 2.05d) were dyed with acid and disperse dyes to investigate the effect of the difference of the fiber fineness. Also X-ray diffraction pattern, birefringence, DSC thermogram, moisture regain and water absorption of these fibers are measured. The dyeing rate of nylon UMF with acid dyes is increased compared with that of regular fiber, but not increased for disperse dyes. Also the saturation dye uptake of UMF with acid dyes is higher than that of regular fiber, while it is unchanged for disperse dyes. The moisture regain of UMF is similar to the regular fiber, whereas the water absorption of UMF is two times th그n that of the regular fiber. The crystallinity percentage of UMF is higher than that of regular fiber.
Effect of Heat Treatment on Dyeing and Physical Properties of Nylon 6 Ultramicrofiber
Textile Coloration and Finishing, volume 14, issue 6, 2002, Pages 328~334
Nylon 6 staple ultramicrofiber(UMF, 0.074) and regular staple fiber (Regular, 2.0d) were annealed at In, 130, 160 and
under tension free for 10 min and U min. The treated fibers were dyed with Acid Red 18 and Blue n3. They were adjusted at PH 5.0 of dye bath in buffer solution of
. Liquor ratio was kept at 1000:1. Dyeing rate of UMF annealed at
was decreased, but was increased for regular nylon. Also dye equilibrium of UMF at
was increased for Acid Red 18, but was decreased for Acid Blue 83. The intensities of X-ray diffraction peaks of UMF increased with increasing annealing temperature. Also the crystallinity of heat-sotted fibers by DSC thermogram was well agreed with the tendency of density Amino end group, moisture regain and water absorbency were decreased with increasing annealing temperature.
The Physical Properties and the Dyeability of Nylon Fibers Prepared by High Speed Spinning at Different Godet Roller Draw Ratio
Textile Coloration and Finishing, volume 14, issue 6, 2002, Pages 335~341
The physical properties and the dyeability of the nylon S fibers Prepared by high speed spinning according to godet roller draw ratio form 1.1 to 1.6 were investigated. The strains of nylon 6 fibers were decreased against the increase of the godet roller draw ratio. The stresses of nylon 6 fibers were increased with the increase of the godet roller draw ratio. Birefringences, densities and crystallinities of the nylon 6 fibers were increased with the increase of godet roller draw ratio In DSC diagrams, the
form of crystal became dominant at higher godet roller draw ratio. The dye uptakes of C. 1. Acid Blue 113 on the fibers were decreased against the increase of godet roller draw ratio.
