The influx of innovation is urgently required to the fiber(textile) engineering education in Korea. In this review, we analyzed the present situation of both the industrial (engineering) ecosystem and the engineering education, and forecasted the direction where the fiber engineering education is going on. Rapid changes such as an increase in income level, a decrease in birth-rate, and reshaping the human lifestyle are taking place in Korea. Continuous improvement is required to the contents and the objectives of engineering education in each program. There are some serious problems for most of the students in universities, including a reduction in the credits for graduation, numerical decrease in entrance as well as graduation, the longer duration in universities, the increase in the unemployment ratio, the paradigm shift in education environment. To cope with the tremendous changes in industrial (engineering) ecosystem, we suggest that an expansion of using convergence technology, specialization for differentiation in education, improvement of educational content, and selective induction of an engineering accreditation system with the help of academic society are inevitable for the sustain-ability of fiber (textile) engineering education.

This paper presents a method of preparing a high-strength sheath/core complex badminton string and examines its playability and durability performance. From repeated experiments at the laboratory scale, it was determined that the tensile characteristics of sheath/core complex strings are better than those of widely used general strings. The key process of braiding, in which the string is prepared by twisting sheath multifilament around the core of a 3-ply monofilament, and the time required for applying a thin layer of coating, have decisive effects on the physical properties. The yarn diameter was found to be optimal when the string was coated three times and the structure of the sheath/core was composed of multifilament 1890d/monofilament 100d. SEM identified an increase in the inner thickness of the sheath/core string with braiding and coating. To conclude, Sample D displayed high tenacity, tensile extension, and tensile strength, which can affect durability, while its tensile modulus was the lowest (54.13 g/tex), which is indicative of good playability.

We have prepared multi-walled carbon nanotube (MWCNT)-embedded conductive composite fibers using polyetherimide (PEI) as a polymer matrix (denoted as PEI-MWCNT). Uniform dispersion of the MWCNTs in dimethylacetamide was achieved after functionalization with quadruple hydrogen bonding sites, after which conductive composite fibers were produced via an electrospinning process. PEI-MWCNT fibers were prepared containing up to 3 wt% MWCNTs, and the resulting fibers were analyzed in order to determine the diameter and electrical conductivity of the fibers. Analysis of the fibers with scanning electron microscopy (SEM) revealed highly porous fiber structures, and that the MWCNTs were well-dispersed within the PEI matrix. Increasing the amount of MWCNTs in the fiber resulted in a decrease in the average fiber diameter, and the electrical conductivity was improved even when only a small amount of functionalized MWCNT was present.

An eco-friendly polyurethane incorporating a soybean-oil-based polyol was synthesized using a prepolymer method, and the chemical structure, molecular weights, and thermal properties of the polyurethane were characterized using instrumental analysis. The disperse and reactive dyeing properties of the eco-friendly polyurethane incorporating the soybean-oil-based polyol were compared to those of conventional petroleum-based polyurethane.

This study examined the optical properties of nanofilament fabrics prepared from polyethylene terephthalate (PET)/modified-PET sea-island bicomponent fibers using an alkali treatment. The luster and anti-transparency properties of the fabrics before and after the alkali treatment were compared. The illuminance of the alkali-treated fabric relative to the position of an illuminometer was higher than that of untreated fabric, except for an illumination angle of approximately
, where much of the light was transmitted through the pores created by the removal of the sea materials. In addition, the alkali-treated fabric exhibited superior anti-transparency properties compared to the untreated fabric. Therefore, the outstanding optical performance of nanofilament fabrics was confirmed.

This research reports the development of a new yarn formation technology that operates on the two-for-one twisting principle, which enhances the twisting performance during the yarn formation process and maintains the standard qualities of the ring spun yarn. The spinning system comprises three components: first twisting component, second twisting component, and bobbin building component. Each operation unit is designed, manufactured, and assembled into a total system. To test the operational feasibility of the new system, two different colored filaments are delivered from the front roller of the draft bank and first twisted by means of a flyer, and second twisted by the take-up guide. The bobbin building motion is also tested. The results indicate that the new two-for-one spinning system works very well. The first and second twists are realized in the corresponding working zone. The bobbin shape is built, whereas the flyer driving torque is transferred to the bobbin. The repelling force of the magnets effectively actuated the take-up guide vertically.

Geotextiles are used extensively to protect soil from erosion. In this study, we evaluated the mechanical properties and degradation behaviors of poly(lactic acid)/poly(butylene adipate-co-terephthalate) (PLA/PBAT) blends. The incorporation of PBAT to PLA decreased the tensile strength and modulus but increased the elongation at break of the blends. Tensile strength and elongation of the PLA/PBAT blend resins were dramatically improved by incorporating a chain extender. When PLA/PBAT blends were composted under
, 90% RH conditions, they showed two-stage degradation and completely lost their mechanical properties after 40 weeks. The PBAT-dominant blend (PLA/PBAT 40/60) showed slightly slower degradation than the PLA-dominant blend (PLA/PBAT 60/40).

The weight reduction and dyeing properties of circular-knitted fabrics, fabricated from sea-island-type polyethylene terephthalate (PET) ultramicrofiber with a single fiber that is approximately 400 nm in diameter, were investigated. It was found that the dissolution ratio was dependent on the process temperature and the concentration of the sodium hydroxide (NaOH) solution used during alkali treatment. The use of a penetrating agent reduced the dissolution rate when using a 1 wt% NaOH solution, but accelerated the dissolution when using a 2 wt% NaOH solution. The dissolution ratio reached its theoretical maximum when the fabric was treated at
for approximately 40-50 min with a 1 wt% NaOH solution and for approximately 15-20 min with a 2 wt% NaOH solution. Under these treatment conditions, a large number of the sea components were dissolved, although some island components were not separated even in the case of treatment at
for 50 min with a 1 wt% NaOH solution, as monitored by scanning electron microscopy (SEM). The use of a cationic dye staining method also allowed for observation of the dissolution behavior. The color yield of the disperse dye on the alkali-treated fabric was dependent on the dyeing temperature, and the K/S value decreased as the dyeing temperature increased from
. The build-up property of the fabric was generally good, the wash fastness was very poor to poor, and the light fastness was poor to fair.
