On the Kubelka—Munk Single-Constant/Two-Constant Theories

As the basic theory for color mixing in intensely light-scattering materials, the Kubelka— Munk single-constant/two-constant theories have played an important role in color science and technology. However, in practice there are some shortcomings. This paper checked the theories with a series of systematical experiments, data processing a..

The Precursory Analysis of the Influence of Garments on Corona Discharge Created Around a Human Fingertip

The aim of the experiment was to analyze the corona discharge films (CDF) taken from fingertips of human subjects who had contact for a long period of time with two sets of clothes, and find out in what way a long period of contact with textiles influences life’s parameters: heart beat, blood pressure, and volunteers’ level of comfort. ..

Quantity and Distribution of Oily Contaminants Present in Flame-resistant Thermal-protective Textiles

This paper reports an experimental study wherein the quantity and distribution of oily contaminants present in flame-resistant fabrics (FR) after contamination and decontamination was determined using radiotracer analysis and scanning electron microscopy. The experimental variables were fabric type, laundry treatment, and number of contam..

Design of Intelligent Garment with Transcutaneous Electrical Nerve Stimulation Function Based on the Intarsia Knitting Technique

This paper describes the work that was carried out on the design for intelligent wearable garment with transcutaneous electrical nerve stimulation (TENS) function from a knitwear design perspective. It is perceived that good design is essential for the development of textile-related products for medical function. The knitwear technique, g..

Preparation of Polyrotaxane Fibers. Part I: Influence of Dope Solvents on the Physical Properties of Wet-spun Polyrotaxane Fibers

The preparation of polyrotaxane fibers by wet spinning of polyrotaxane, consisting of poly (ethylene glycol) (PEG) and α-cyclodextrins (α-CDs), was examined using three different types of dope solvents: dimethylacetamide (DMAc) containing 8 wt% lithium chloride (LiCl), dimethylformamide (DMF) containing 8 wt% LiCl, and dimethylsulfoxide (..

Influence of Relative Humidity on Textile Antenna Performance

The next generation of garments is sensorized, and therefore requires an adapted wireless communication tool such as a textile antenna. However, when integrating this flexible antenna into clothing, stable and reliable functioning in the operating frequency range is required. Climatic changes, especially altering relative humidity, might ..

The Fine Structure of the Kapok Fiber

The fine structure of kapok fiber was investigated by transmission electron microscopy. The walls of the fibers contained five layers, observable both in lateral and in longitudinal cross- sections: the cuticle, S; primary wall, W1; secondary wall, W2; tertiary wall, W3; and inner skin, IS. W1, with a thickness of about 200 nm, was charac..

KOTITI, 성남에서 새 시대 열어

KOTITI(한국섬유기술연구소, 이사장 김정수)가 신사옥이 건설된 성남에서 새 시대를 열었다. 지난 15일과 17일 양일로 나눠 가진 행사에서는 KOTITI 회원사와 업계, 학계 원로들과 랩투어(Lab Tour) 및  섬유업계 정보 교류회를 동시 개최해 관심을 얻었다. KOTITI 신사옥은 지난해 9월 성남시 중원구의 지식산업센터 내 사옥을 매입한 후 시험연구 설비를 확충, 2월..

Numerical Study of the Three-dimensional Flow Field in Compact Spinning with Inspiratory Groove

In compact spinning with inspiratory groove, the computational fluid dynamic model, computed with parallel technologies and Fluent 6.3, was developed to simulate the flow field in the compact zone with 3D computational fluid dynamic technology. Flowing state, distributions of static pressure and velocity in the compact zone were character..

Sound Absorption Behavior of Knitted Spacer Fabrics

This paper presents an experimental investigation on the sound absorption behavior of knitted spacer fabrics. Both weft-knitted and warp-knitted fabrics were used in the study due to their different structure features. The weft-knitted spacer fabric used was composed of two varied plain knitted outer layers and one textured polyester mult..
