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.

본 연구에서는 마찰하전형정전선별법을 적용하여 폐플라스틱 맥주병(PET, Nylon)의 재활용을 위한 재질분리 연구를 수행하였다. 하전재질 선정을 위한 하전특성 연구결과, PMMA가 폐플라스틱 맥주병(PET, Nylon)의 재질분리에 가장 효과적인 하전재질로 확인되어, PMMA를 사용한 pipe line와 cyclone 하전장치를 개발하였다. 본 연구에서 개발된 pipe line과cyclone 하전장치를 이용한 재질분리 실험결과, 최적 실험조건에서 PET의 품위와 회수율이 각각 99.6%와 88.2%인 결과를 얻어, 폐플라스틱 맥주병(PET, Nylon) 재활용을 위한 재질분리 기술을 확립하였다.

플라스마 표면처리는 전체적인 물성은 유지하고 표면의 특성만을 변화시킨다고 전해지고 있다. 이번 연구에서는 플라스마 처리에 의해 높은 발수성을 나타내는 나일론 6 섬유로의 개질을 시도하였다. 발수성을 나타내는 나일론 섬유는 가스 종류, 처리시간, 인가 파워를 변수로 하여 RF 진공 플라스마 시스템에서 처리되었다. 플라스마 처리된 섬유의 표면을 scanning electron microscopy(SEM)과 atomic force microscopy(AFM)으로 모폴로지 변화를 살펴보았으며, 기계적 특성과 고분자 고유의 특성을 인장강도와 Differential scanning calorimetry(DSC), thermo-gravimetric analysis (TGA)로 각각 분석하였다. 또한 나일론 섬유의 발수성 평가는 물방울 흡수시간으로 테스트를 실시하였다. 이러한 결과들은 플라스마 표면처리로 인해서 나일론 섬유의 발수성이 향상됨을 나타내었다.

Some of novel halogen-free, elastomeric flame retardants for nylon-6 have been developed. It is found that the S-ENP and clay have a synergistic flame retardant effect on nylon-6 resulted from the formation of two barriers on the nanocomposite residue surface at the end of combustion. A novel flame retardant ternary nanocomposite of nylon-6/ENP/nano-Magnesium hydroxide was also fabricated. The new ternary composite has better flame retardancy and thermal stability than the conventional one because nano-MH can disperse much more homogeneous in the new ternary composite than in the conventional one.

In this research, split-type complex yarn of 20:80, 40:60, 50:50 nylon6/polyester composition ratio was used in order to impose unique sense on split-type complex woven. After treating both split-type complex yarn of each ratio and its produced woven in alkali solution, we got the following results by checking physical properties based on alkali proportion and treatment time. Under the condition of NaOH 20% in this experiment, it took approximately double time 20% loss of weight. The loss of weight became high when polyester proportion of N/P(nylon6/polyester) composition ratio was low, in the same fineness yarn. Even though polyester proportion was low, the loss of weight was low when the fineness was high. N/P division was well processed at about 25% loss of weight under the condition of NaOH 20%, treatment temperature $50^{\circ}C$, and treatment time 60 minutes. The research provides that the loss of weight should be processed around treatment time 24 hours in the case of NaOH concentration 15%, and treatment time 15 hours in the case of NaOH concentration 18%, respectively, in order to achieve N/P woven division ratio of about 70%-80% in industrial fields.

Melt blends of maleic anhydride grafted polypropylerle(PP-g-MA) and Nylon 6 were prepared to study the influence of chemical reaction between the two polymer components. By adding the MA grafted polystyrene pold (ethylene/butadiene) and polystyrene[SEBS-g-MA] as the compatible modifiers to reinforce the impact resistance, the Izod impact strength, high rate impact strength and morphology were studied. The notched Izod impact strength increased with the content of PP-g-MA and SEBS- g-MA. The energy of high rate impact strength increased as the thickness of specimen increased, while, it increased as the specimen displacement decreased. In the morphology observed by SEM, finally, we confirmed the improvement of the compatibilization and interfacial adhesion with the content of SEBS-g-MA. The continuous phase of PP-g-MA was the main cause of the modified properties.

제주도 고등어 자망어업의 주어기인 1974년 5월 28일부터 8월 31일까지 서귀포와 비양도근해어장에서 고등어 자망어구의 이망율에 관한 시험조업결과는 다음과 같다. 1. $X^2$ t 검정에 의하면 고등어 nylon-monofilament 자망 B형이 nylon-multifilament 자망 A형보다 이망성능이 우위하고 나망율비는 $m_A:m_B=1:1.8$이다. 2. 망목 75mm인 nylon-monofilament 자망 C형, D형이 망목 85mm인 nylon-monofilament 자망 E형 F형 보다 이망성능이 우위하고 이망율비는 $m_E{\cdot}F:m_C{\cdot}D=1:2.8$이다. 3. 망계 굵기가 120tex와 75tex이고 망목이 75m 및 85mm인 C, D, E, F, 형에서는 상호간의 우위는 모두 확인할 수 없었다.
