This study reported the dual functional self-cleaning PET fabrics prepared from $TiO_2$ and hexadecyltrimethoxysilane treatment, which have photodegradation and superhydrophobicity on the fabric surface. Phodegradation and superhydrophobicity of the resulting fabric were compared with $TiO_2$ or silane treated fabrics. The dual functional self-cleaning PET fabric showed less photodegradation than the $TiO_2$ treated fabric. However, the dual functional self-cleaning fabrics showed superior superhydrophobicity to silane treated fabric with increased water contact angle and significantly decreased roll-off angle. This suggested that the dual functional PET fabric has a great potential to be the commercialized self-cleaning fabric because it is repellent to soil or dust and even if soil or dust is adsorbed on the fabric surface, it can be removed by water rolling off on the surface or photodegradation by the photocatalyst.

Dyeing properties of silk fabric with leaf Mustard was investigated the relation with pH variation, mordants, mordant method. K/S value shows the following sequence: pH 3>pH 5>pH 7>pH 9. K/S value shows high in post mordant conditions. Silk fabric shows the green, blue tone according to mordants(Al, Cu, Fe mordants). The tannic acid treatment silk fabric shows higher than the nontannic acid treatment silk fabric in K/S value. Lighting fastness of tannic acid treatment silk fabric shows better than that of nontannic acid treatment in Cu, Fe mordants. Water fastness of tannic acid treatment silk fabric was wholly improved. Tannic acid treatment improved dyeing properties of silk fabric with leaf Mustard.

In this study, the properties of polypropylene(PP) non-woven fabric spun under various conditions by the Melt-blown method were verified, and the deodorant content and deodorization of PP non-woven fabric after deodorant-treatment were investigated. PP non-woven fabrics are manufactured by varying the temperature of spin beam, hot air temperature and amount, the RPM of collector R/O and the distance between collector and spinneret, which affects the structure of the non-woven fabric. After that, the structural characteristics and air permeability of the non-woven fabric were measured. The experimental results show that the amount of air, the distance between the collector and the spinneret significantly affect the structural characteristics and air permeability of the PP non-woven fabric. And, regardless of the weight of the PP non-woven fabric, the deodorizing effect of UiO-66 MOF deodorant add-on ratio and content was higher.

The purpose of this study was to research the efficient tool of the exclusive fabric simulation in Jacquard Textile CAD system. For performing this design study, it designed the surface design of the abstract images of flowers through EAT Designscope CAD system and simulated the interior fabric. To merchandise the fashion items and see the visual image, these fabric simulations was effected by two or three-dimension modeling through EAT designscope, YongWoo CNI, Alias and so on. The result of this study can be summarized as follows. Before the step of weaving the samples from the surface design works, jacquard fabric design can be done very efficiently to apply the design step of the fabric simulation in CAD(Computer Aided Design). As the usage of the simulation tool in CAD system, jacquard design can be easily feed-back to modify for the right fabrics and produced the various designs in the short running time very efficiently. Therefore, this jacquard design system ultimately can be saved cost and developed the higher value-added goods in more response to consumer demands.

Quality inspection of textile products is an important problem for fabric manufacturers. This paper presents an automatic vision-based system for quality control of web textile fabrics. Typical web material is 1-3m wide and is driven with speeds ranging from 20m/min to 200m/min. At the present, the quality assessment procedures are performed manually by expert. But worker can not detect more than 60％ of the present defect and inspect the fabric if moving faster than 30m/min. To increase the overall quality and homogeneity of textile, an automated visual inspection system is needed fur the productivity. However, the existing inspection system are too expensive to purchase for small companies. In this paper, the proposed PC based real-time inspection algorithm gives low cost textile inspection system, high detection rate with good accuracy and low rate of false alarms. The method shows good results in the detection of several types of fabric defects.

A new flame retardant diphenyl butylamidophosphate (DPBAP) for PET fabric was synthesized and its flame retardancy was examined. The results have shown that PET fabrics treated by DPBAP(with DPBAP and on 4-10 %) show excellent flame retardancy. Since the DPBAP treated PET fabric show essentially no change in the drape stiffness and the tensile strength, it is believed that DPBAP is chemically stable in PET fabric. In addition to this, the washing fastness of DPBAP on PET fabric tested by the 5 times of water washing method also appeared to be excellent. Judging from the fact that DPBAP was synthesized from relatively cheap material as well as the above cited DPBAP properties as a good flame retardant, the potential of DPBAP to be developed as a commercial flame retardant for PET fabric seems to be high.

일반적으로 원단 후가공시 원단의 가장자리를 핀으로 고정하게 되는데, 이때 원단의 고정 부분의 흠집으로 인해 감긴 원단의 포장 보관 시 변사부분이 부풀어 올라 전체적으로 원단의 변형이 발생한다. 원단의 변형 및 손상은 섬유제품의 품질 저하로 이어지기 때문에 원단 변사부분의 검출은 원단 마무리 가공에서 반드시 필요하다. 본 연구에서는 원단제조시 제품의 품질을 좌우하는 자동 변사 커팅(auto selvage cutting)시스템에 사용하는 비접촉식 변사검출 센서를 연구하였다. 이를 위해 32개의 센서를 2.5mm 간격으로 배열하여 감지하는 센서시스템을 개발하였고 이변사검출센서 시스템으로 실제 변사 검출이 가능한 것을 실험으로 확인 하였다.

The data for application of mordanting is shown in this experiment by researching dying properties of iron-dye process and concentration changes using persimmon. The strength of persimmon-dying fabrics was controlled by diluting persimmon dye with water and iron mordanting showed the possibility of textile design. The experiments were performed with various conditions processed with iron mordanting liquid by adding water to persimmon-dying liquid and drying well. The most dark color of fabric is observed with the pure persimmon dying without adding water. As the adding water is increased, the color of the fabric is getting lighter with the amount of adding water. After process of iron mordanting, dark color of the fabric turns into dark grey and light color turns into light grey. The possibility of persimmon dying with fabric can be applied in the design of textile with deepened color.

In this the study, polyester/cotton(P/C) blended fabrics with fine denier were developed to get the light weight compared with the traditional P/C blended fabrics. Moreover, the width of the fabrics was extended by the tenter during the final heat treatment to get the lower fabric density and lighter weight. Then, the physical properties of these fabrics were analysed. The results were as the follows: The developed fabrics had 22.6-31.6% lighter weight than the traditional fabrics with the same fabric width. The weight of fabric decreased drastically with the fabrics width down to 67.1 $g/m^2$. The fabric density for the warp direction decreased with the fabric width. The tenacity and the elongation of the developed fabrics was little lower than that of the traditional fabrics. The air permeability of the developed fabrics increased with that of the traditional fabrics. The stretch rate of the developed fabrics decreased with increasing the fabric width. Residual stretch rate of the developed fabrics was more stable than that of the traditional fabrics. Residual stretch rate of the developed fabrics increased with the fabric width, but the highest value was less than 5% which is quit stable.

Aiming at the defect detection quality of denim fabric, this paper designs an improved algorithm based on the optimized Gabor filter. Firstly, we propose an improved defect detection algorithm of jean fabric based on the maximum two-dimensional image entropy and the loss evaluation function. Secondly, 24 Gabor filter banks with 4 scales and 6 directions are created and the optimal filter is selected from the filter banks by the one-dimensional image entropy algorithm and the two-dimensional image entropy algorithm respectively. Thirdly, these two optimized Gabor filters are compared to realize the common defect detection of denim fabric, such as normal texture, miss of weft, hole and oil stain. The results show that the improved algorithm has better detection effect on common defects of denim fabrics and the average detection rate is more than 91.25%.
