  • Organic acid salt of fatty polyamide (DDDT) and acrylate of fatty carbamide (DDTCA) were synthesized as a main component for the softener. O/W type non-ionic softener (NSC) was prepared by blending DDDT and DDTCA with beef tallow, lanolin anhydride. polyoxyethylene(7) stearyl ether, and polyoxyethylene(50) oleyl ether. After treatment of NSC to all cotton fabrics, the physical properties such as tear strength, crease recovery, and flexing abrasion resistance were measured. As a result of the measurement, NSC was proved to be durable non-ionic softener with good softness.

  • To manufacture toilet tissue with ONP (old newspaper), the effect of fractionation fiber (R150, R100, R70 mesh) and bleaching(P, PY), blending (70/30) with MOW(mixed office wastepaper) or WL(white ledger) and the addition of softener on the optical and mechanical properties were studied. Considering the pulp yield, brightness and strengths, fibers of R100 mesh fraction were proper to be produced to toilet paper from ONP. This pulp showed the pulp yield of 76.8%, brightness of 50.2% ISO and tensile index of 21.1 Nm/g. By the bleach with P and PY stages, the brightness of the pulps increased up to 60.3% ISO and 61.8% ISO, respectively. When blended with MOW (57.3% ISO) or WL (76.2% ISO), the brightness of the former increased up to 58.5% ISO, the latter up to 63.6% ISO. The strengths of pulp blended with WL were higher than those of fractionated pulp from 100% ONP, however there was no difference in strengths between fractionated pulp and blended pulp wth MOW. While the addition of softener improved the softness of paper, but it decreased strengths of pulp and extended dispersing time in water.

  • Fatty polyamide that gives softness, lubrication and bulky property and alkyl imidazoline that gives durable softness and antistatic property were synthesized. then, an O/W-type durable softener (DSN) was prepared by the emulsion of the synthesized fatty polyamide and alkyl imidazoline. Emulsion stability of the DSN was good, and the mixed HLB value was 11.2. From the measurement of softness, lubrication, antistatic property, bending resistance, and color fastness, it was proved that the prepared DSN was a good durable softener for nylon.

  • We examined the antimicrobial effects of the cotton fabrics which were laundered at different conditions and treated with a colloidal silver solution using Staphylococcus aureus. Colloidal silver solution was made from commercial colloidal silver generator by electrolysis. The fabric which was innoculated and washed with water before drying had no more Staphylococcus aureus, but which was innoculated and dried before washing with detergent solution had lower reduction rate. The fabric washed with oxygen bleach did not have an antimicrobial effect, but rinsed with 0.07% fabric softener showed antimicrobial properties. The fabric rinsed with 0.7ppm colloidal silver solution had better antimicrobial effects. As the treating concentration of silver solution increased, the antimicrobial property of the fabric was increased. The fabric treated with 5% silver solution sustained reflectance and whiteness of untreated fabric. The colloidal silver treated fabric lost antimicrobial property after washing because nano-sized silver particles were located on uneven fiber surface without chemical bonding forces.

  • Superior hydrophilic properties will allow varieties of polyester(PET) fiber materials, fabrics and industrial materials a broader scope of use. The purpose of this study was to investigate the effect of water-absorbent softener treatment on the end-use properties and the hand of polyester knitted fabrics. Two different fabrics were knitted for the summer ladies' outwear; PET jersey and PET mesh. Variables were softner treatment and stitch type(jersey and mesh). Mechanical properties of the fabric samples were measured by KES-FB system. From these, primary hand values(HV) were evaluated by the conversion equation (KW-403-KTU) and the total hand value(T.H.V.) was calculated according to the KN-304 Summer. Both water-absorbent softner treatment and stitch types affected mechanical properties and hand values of PET fabrics. Mesh were thicker than single jersey stitch. As they became thicker, tensile, shear, and compressional energy increased. It appeared that coefficient of friction of mesh stitch was larger than that of single jersey stitch. The coefficient of friction and the mean deviation of surface roughness were decreased by softener treatment. After softner treatment KOSHI and SHARI of the both PET jersey and PET mesh decreased. However, FUKURAMI values of PET jersey increased and that of PET mesh decreased. The T.H.V. of the treated PET jersey was lower than that of the untreated one, while the T.H.V. of the treated PET mesh was higher than that of the untreated one. Overall T.H.V. of the single jersey was better than that of the mesh before and after softner treatment.

  • This paper suggests the optimal conditions for the laundry to prevent from the electrostatic charge by the evaluation of the electrostatic characteristics in the full process of washing and drying. Cotton, nylon, and polyester fabrics were used as test washing specimens. Detergent and softener were used under the standard washing cycle, and then the electrostatic characteristics of laundry were measured. The results showed that the moisture regain decreased and the electrostatic charge increased with the drying time. It was observed that the specimen fabrics were already dried up before the standard drying cycle was finished. Consequently, the excessive drying caused a generation of electrostatic charge due to the removal of the trace of moisture remaining and the excessive friction. Especially, the softener played an important role to prevent from a generation of electrostatic charge, whose insertion was more effective in the drying than in the rinsing process. It was also shown that the electrostatic charge could be decreased by drying the fabrics of one kind. On the other hand, for drying the mixed kinds of fabrics, the electrostatic charge increased remarkably. Therefore we suggest that the laundry be classified according to the kinds of fiber, and then be washed and dried before excessive drying to reduce electrostatic charge And further, a proper use of softener is effective to reduce electrostatic charge.

  • In order to prepare a softener, alkyl imidazoline salt, fatty carbamide salt, and fatty polyamide salt were synthesized first, and then the synthesized salts were blended. The prepared softeners were applied to acrylic fibers, and then several properties were tested. As a result, the prepared softeners show good softening and lubricating properties, and they also show a little antistatic property. Through bending resistance tests and measurements of feeling change of acrylic fibers treated with the softeners, it was proved that the prepared softeners are durable softeners.
