  • Cotton fabric was treated with TiO$_2$-PEG600 mixed solution by pad-dry-cure and wet-fixation process to improve the performance properties as well as antibiosis effect and its laundering durability. In this paper, the effects of concentration of $TiO_2/PEG$ and fixation process were investigated on laundering durability and properties of cotton fabric treated with glyoxal. As the concentration of $TiO_2/PEG$ increased fixation, W.I., K/S of treated cotton fabric increased. Application of wet-fixation method provided a further improvement in fixation, laundering durability of treated cotton fabric.

  • The dish cloth requires antimicrobial activity for hygienic purpose. Until now, organic antimicrobial agents of low cost have been frequently used for the anitimicrobial finishing. However, a cleaner hving anitimicroial activity should be more durable considering consumers' ever-increasing expectation. In this study, the cleaner containing the bamboo fiber were finished with a formulation of a new zirconium-containing inorganic agent of zirconium phosphate and polyurethane binders. The optimum treatment condition was investigated. And its durability against repeated laundering cycles was assessed. The existence of Zr after the repeated laundering was verified and the antimicrobial effect did not decrease under 30 washing cycles.

  • Wool fabric having high moisture content were treated with fluorocarbon-based water and oil repellent finishing agents by pad-dry-cure system. Three types of finishing agents which were regular-type or nano-type were adapted to compare the surface chemical composition, water and oil repellent property, crease recovery angle, and durability to repeated laundering. From the surface chemical compositions resulted by ESCA and C1s curve-fitting, it was shown that the regular-type finishing agent were easily taken off from the finished wool fabrics after repeated laundering. On the other hand, the fluoroalkyl groups of nano-type finishing agents turned round from fabric surface to fiber internal after repeated laundering. The water repellency of the wool fabrics treated with regular-type agent had a little changes according to the treatment condition changes and sharply decreased with repeated laundering. However, these values when treated with nano-type agents increased with the concentration and cure temperature and were maintained after 20 times laundering. The wool fabrics treated with nano-type agent had a great oil repellency irrespective of treatment conditions. Furthermore, the wrinkle recovery values of the wool fabrics treated with nano-type agents were higher than those of the fabrics treated with regular-type agent and were unchanged after 20 times laundering.

  • Cotton fabric was treated with chitosan by pad-dry(-cure) method to impart antimicrobial properties. Four chitosans of different degree of deacetylation (DAC: 65~95%) with similar molecular weight(MW: ca. 50, 000) and one chitosan oligomer(MW 1, 800, DAC 86%) were used. In order to improve the durability to laundering of antimicrobial activity for the fabrics treated with chitosan oligomer, crosslinker or binder was included in the finishing formulation. Antimicrobial activity against Staphylococcus aureus and Proteus vulgaris was evaluated by the Shake Flask Method. The treated fabrics were laundered up to 20 times according to AATCC Test Method 60-1986 or JIS 0217-104 and antimicrobial activity of the laundered fabrics was evaluated. The antimicrobial activity was increased with the increase of concentration and degree of deacetylation of chitosan. And the cured fabrics showed better durability to laundering than the not-cured fabrics according to AATCC Test Method 60-1986. Crosslinker and binder decreased antimicrobial according of the fabrics treated with chitosan oligomer and were not effective to improve the durability to laundering according to JIS 0217-104.

  • To develop a waterproof breathable material, we fabricated three kinds of nanofiber web laminates using a massproduced electrospun nanofiber web with different substrates and layer structures. The waterproofness and breathability of nanofiber web laminates were evaluated after repeated launderings and compared with those of conventional waterproof breathable fabrics currently in use, including densely woven fabric, microporous membrane laminated fabric, and coated fabric. The durability of nanofiber web laminates, including adhesion strength, abrasion resistance, tensile strength, and tearing strength, was also assessed and compared with those of conventional waterproof breathable fabrics. The water vapor transmission of nanofiber web laminates increased slightly after repeated launderings, whereas the air permeability somewhat decreased after launderings but still maintained an acceptable level of air permeability. Laundering reduced the resistance to water penetration of nanofiber web laminates, which implies that laminating techniques or substrate materials that could support waterproofness of the laminated structure should be explored. The adhesion strength, abrasion resistance, tensile strength, and tearing strength of nanofiber web laminates were in a range comparable to conventional waterproof breathable materials.

  • This study shows the optimum attachment of Two-Way Shape Memory Alloy (TWSMA) springs onto thermal liner and its sewing method for the mass production of fire fighter's intelligent turnout gear. SMA springs were attached to the fabric by four different methods and stitched by two different shapes (square and wave). The durability of the attached springs was tested by laundering up to 50 cycles. Examined were whether the springs would remain attached to the fabric after repeated laundering, the shape memory effect and reaction of the springs, and the anti-corrosiveness of the springs. A Human-Clothing-Environment simulator evaluated thermal insulation according to attachment methods, air layer volume, and stitch types. The findings showed that silicon attached springs remained intact after repeated laundering; in addition, repeated laundering did not influence the responsiveness and anti-corrosiveness of SMAs. Air volume had positive relations with the insulation. Attachment methods or stitch methods had limited impact on the thermal insulation. As a result, a wave type stitch with silicone attachment was suggested as the optimum method to attach the SMA springs onto the intelligent turnout gear for fire fighters.

  • The purpose of this article is to investigate the effect of $O_{2}$ 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.

  • Hexachloro-cyclophosphazene(HCCP), a formaldehyde-free flame retardant (FR), was steam-cured with triethanol amine(TEA) to impart durable flame-retardancy to cotton fabrics. While the HCCP treatment alone showed very limited resistance to repeated laundering cycles, the addition of TEA substantially improved the laundering durability of the FR cotton up to twenty laundering cycles. The extended washing resistance was accomplished by the increased nucleophilic substitution of unreacted P-Cl groups in HCCP by the TEA resulting in the more densely crosslinked FR networks. With increasing molar ratio of TEA to the HCCP up to 2, the flame retarding effectivity and the synergistic effectiveness improved to 2.8 and 1.8 respectively. TGA and microscale combustion calorimetry verified the pyrolysis and combustion behaviors of the FR-cotton, which showed lower maximum pyrolysis and combustion temperatures together with substantially decreased peak pyrolysis and heat release rate, synergistically yielding larger amounts of carbonaceous chars. The formaldehyde-free HCCP and TEA can be a durable FR finishing agents for cotton fabrics acting through a solid-phase flame-retarding mechanism.
