  • Plasma polymerization in prepared glow discharge was carried out to improve the bathochromic of dyed PET fabrics by using silicon containing vinyl monomer in plasma polymerization equipment which consists of a pair of electrodes was connected to the 13.56MHz RF generator. The optimum condition for the bathochromic effect was investigated on various plasma polymeriztion parameters. By plasma polymerization used silicon containing vinyl monomer, the bathochromic of dyed PET fabrics was very enhanced. The optimum conditions on this equipment were as follows ; electrode distance : 3cm, discharge output : 60W, gas pressure : 0.3 Torr, monomer flow rate : 30㎤/min. plasma polymerization time : 60sec. The apparent strength of plasma polymerized PET fabrics was increased about 40∼47% with decreasing about 3 of L value.

  • This article describes the change of hand value of chitosan crosslinked cotton fabrics. The chitosan crosslinked cotton fabrics were manufactured by mercerizing process using epichlorohydrin(ECH) as crosslinkins agent, 2% aqueous acetic acid as a solvent of chitosan and ECH, and 20% aqueous sodium hydroxide as a mercerizing agent and crosslinking catalyst. Cotton fabrics were dipped in the mixed solution of chitosan and ECH, picked up by mangle, mercerized and crosslinked in NaOH solution, and finally wash and dry. Mechanical and physical properties of the chitosan crosslinked fabric were investigated using Kawabata Evaluation System(KES) and other instruments. Tensile energy and tensile strain were decreased with the increase of the concentration of chitosan. Tensile resilience, compression resilience bending rigidity, bending hysteresis, shear stiffness, shear hysteresis, coefficient of friction, geometrical roughness, compression linearity, compressional energy, and thickness were increased with the increase of the concentration of chitosan. On the other hand, bending rigidity, bending hysteresis, coefficient of friction, geometrical roughness, compressional resilience, and thickness were increased with the increase of the concentration of crosslinking agent(epichlorohydrin).

  • The dyeing of poly(trimethylene terephthalate)(PTT)/silk mixture fabrics can be accomplished by a two bath dyeing method with separate application of the disperse dyes on the PTT, reduction cleaning of the stained silk and then dyeing the silk with the acid dyes, or by one bath dyeing method with mixed dye ranges, possibly followed by a cleaning treatment. The two bath dyeing method has the advantage of better results with respect to dry cleaning fastness properties thanks to the possibility of an intermediate reduction clear. On the other hand, as compared with the two bath dyeing method, one bath dyeing method with a mixed dye range permits rapid and more reproducible dyeing, without the risk of great difference with respect to the shade of the strike on both substrates as well as savings of time, energy and water usage. This study was carried out to investigate dyeing characteristics of PTT/silk mixture fabrics with disperse dyes/acid dyes by one bath dyeing method in comparison with two bath dyeing method in the interests for rationalization of the dyeing process.

  • In order to dye nylon/cotton blended fabrics in solid colors with only acid dyes, a hetero-bifunctional bridge compound (DBDCBS) was examined. The bridge compound was designed to react only onto cotton fabrics first, on which amino-containing acid dyes react later by covalent bonding. By the effect of DBDCBS, amino-containing acid dyes exhibited high affinity toward the cotton fabrics. From the dyeing properties examined at various conditions, the optimum dyeing was decided at pH 4 and $100^{\circ}C$. Consequently, the solid color was obtained on nylon/cotton blended fabrics in one bath dyeing process using only acid dyes. The DBDCBS did not show any negative effect on nylon side in terms of dyeing and physical properties.

  • The wearing comfort of garment is governed by two kinds of characteristics such as moisture and thermal transport properties and mechanical properties of fabrics. The porosity influenced by yarn and fabric structural parameters is known as main factor for wearing comfort of garment related to the moisture and thermal transport properties. This study investigated effect of porosity of composite yarns to the moisture and thermal comfort properties of composite fabrics made of hollow composite DTY and ATY yarns. The theoretical porosity and pore size were inversely proportional to cover factor of fabric, but cover factor was not correlated with experimental pore size. The wicking property of hydrophobic PET filament fabric showed inferior result irrespective of porosity, pore size and cover factor. The drying rate was superior at composite fabrics with high pore size and low cover factor, and pore size was dominant factor for drying property. On the other hand, thermal conductivity of composite fabric was mainly influenced by cover factor and not influenced by porosity. Air permeability was influenced by both porosity and cover factor and was highly increased with increasing porosity and decreasing fabric cover factor.

  • To develope a high value-added fiber products which is useful in the human body physiology, the Macban stone was deposited on the PET fabric by sputtering and its effects were investigated. Then, a Macban stone target was prepared for sputtering treatment and treated on the PET fabric by RF sputtering process. After treatment, surface observation by SEM, far-infrared emissivity and emissive power, the fastness to washing and light, bacteriostatic rate, electrostatic, drape stiffness, and breaking strength of PET fabric were investigated. From these investigation, the following conclusions were obtained. 1) The Macban stone was able to deposit on the PET fabric, by the RF sputtering treatment which is eco-friendly dry textile finishing. 2) The far-infrared emissivity and emissive power of sputtered PET fabrics were increased. 3) When PET fabric was treated by sputtering with Macban stone, the amount of deposited Macban stone increased with increasing treatment time and it was deposited on the fabric surface firmly. 4) The bacteriostatic rate of sputtered PET fabrics was about 20%. 5) The electrostatic charge of fiber surface was reduced by sputtering. 6) The fastness washing to light of dyed fabric were improved by the deposition of Macban stone, but the breaking strength was not changed by sputtering. 7) The drape stiffness of sputtered PET fabrics increased with increasing treatment time.

  • We evaluated the seam characteristics with finishing, seaming and sealing processes and seam Puckering behavior of the breathable waterproof fabrics with laser scan. There were differences in 99% significant level between the seamed fabric and the sealed fabric. Seam breakage was initiated with the breakage of sewing thread, so the seam strength after seaming was almost uniform. The sewn seam strength and elongation increased with sealing process in all finishing methods. Pucker grade of laminating type was generally much higher than that of the coating type. We confirmed that wave length and amplitude have more important meaning than the number of weave in the breathable waterproof fabrics. The puckering in breathable waterproof fabrics is mainly occurred by inherent and feeding pucker. The former if due to the insertion of sewing thread and the littler is caused by differential feeding when two pieces of fabric are fed into the gap between a press foot and needle plate.

  • 3-(Hydroxyphenyl phosphinyl) propanoic acid (HPPA) has been one of the most commonly used durable flame retardant agents for polyethylene terephthalate (PET) for many years. We intended to explore the application of HPPA to cellulose fabrics as formaldehyde-free phosphorus based flame retardants (FRs) through green chemistry process. The flame retardancy of the flame-retardant treated cellulose fabrics were characterized by using inductively coupled plasma spectroscopy (ICP) and limiting oxygen index (LOI). Structural changes of the treated cellulose fabrics were carried out by thermogravimetric analysis (TGA) and Fourier transform infrared (FT-IR) spectroscopy. To enhance the flame retardancy of HPPA treated cellulose fibers, glycerol polyglycidyl ether (GPE), a crosslinking agent was employed. Both HPPA and GPE treated cotton fabric imparted an LOI value over 26.
