Analysis on Interlacing Behavior of Multifilament Yarn Using High Speed Camera
Cho Dae-Hwan ; Jeong Young-Jin ;
Textile Science and Engineering, volume 43, issue 2, 2006, Pages 53~59
An attempt is carried out to make the knots in multifilament yarns with conventional interlacer that is controlled to investigate the relationship between the interlacing results and processing conditions. In order to analyze the multifilament movements in interlacer, images of multifilament yams in real time using high speed camera are captured. The physical properties of interlaced yarn are measured to evaluate the influences of two processing conditions, namely, air pressure and yarn tension. Interlacing properties that are caused by the changes of process conditions based on the captured images are analyzed. The mechanism of interlacing in interlacer with the captured images of consecutive multifilament movements were inferred. The movements are classified into several stages according to the status of knot formation which is mainly dependent on the process conditions. Experimental results can be utilized in producing the optimum interlaced yarns for end-use application.

In this study, the effect of fixation methods, relaxation treatment and washing treatment on the comfortable properties of MDPPA/HMM treated cotton weft-knitted fabrics was studied. As a result, 1) Air permeability of knitted fabrics decreased after flame resistant treatment. Single jersey and 10G showed higher value of air permeability than those of interlock and 14G. Swelling agent and wet fixation method which increased the values of W/T and decreased the values of WC/W resulted in decreased values of air permeability. 2)
of knitted fabrics decreased after washing treatment.
of knitted fabrics increased with decreasing air permeability 14G showed higher value of
than those of 10G. 3) Water absorption of knitted fabrics increased after relaxation treatment. Water absorption of knitted fabrics increased with increasing the value of W/T. Water absorption of knitted fabrics is more affected by the structure of fabrics rather than the effect of treatment.

Traditional Korean ramie fabric is called Hansan-mosi. In Korea, many people have known Hansan-mosi. Hansan-mosi is produced by splitting, connecting, length-setting, skein-making, treating, winding and weaving from Taemosi. Recently, in spite of increased demand on the traditional fabrics by eco-friendly living pattern, Hansan-mosi is still very expensive and not widely popularized due to simple color and formation. Hansan-mosi has traditional handicraft shape and intangible cultural assets. In this study, ramie-spinning and carded wool-spining process, were used to develop technology that can produce Hansan ramie fabrics in large quantities. Alkali degumming was conduced for remove pectin quality (
) of Taemosi that was obtained through decortication from trunk of ramie plant. Optimum condition was achieved at 5% concentration, 120 minutes,
temperature. Degummed ramie fiber was made to sliver, we producted 100% Hansan-mosi spinning yarn with low count yarn (10 lea) to high count yarn (80 lea).
3-Dimensional Structural Characteristics and Surface Hairiness of Rotor Spun Yarns

Yarns manufactured by non-conventional spinning methods have mechanical properties that are different from those of the conventional ring spun yarns. This provides difficulties in optimizing successive processes such as weaving or knitting processes. Rotor spun yams have a specific fiber arrangement and thus an intrinsic internal structure that deviates from those of ring spun yarns due to the different twist insertion mechanism. This research reports on the 3-dimensional structural characteristics of the rotor spun yarns. We used the tracer fiber method in combination with the 2-dimensional refractive images, which enabled to perform the 3-dimensional analysis of yarn structure by the image processing technology. Results showed that the fiber trajectories of the rotor spun yarn were of its own characteristics. The constituent fibers are concentrated mostly around the radial position of half the yarn radius, whereas the fiber locations spread in a relatively narrow range. Internal structure of the rotor spun yarns remained unchanged in the low or middle level of twists. In a high twist level, however, the yarn structure changed significantly according to the twist, which could be confirmed though the migration factor and orientation angle distribution. Increasing twists resulted in a more hairy yarn, however the hair length became shorter.
Expanded Model of the Dynamics of the Weft Density and Its Simulation

Modern weaving machines have the beat-up mechanism whose front position is predetermined mechanically. Therefore the relative position between the reed front and the clothfell plays an important role in producing the high quality fabrics with uniform weft density distribution. This research reports on the results from the simulation that was conducted on the basis of the theoretical model about the fabric weft density dynamics, including the factors such as beat-up motion and warp tension. Results showed that the weft density change was very sensitive to the initial clothfell position. The clothfell position was relocated toward the machine front during the machine restart and then it approached the steady state value. A low initial warp tension led to a narrow pickspace, too. Even though the warp tension and the beat-up force changed for a long period of time after the machine restarted, the weft interval variation and the clothfell position change were stabilized early, while the clothfell position showed an overshooting behavior for a low initial warp tension under a high level of process tension condition. Initial weft interval condition showed no influence on the dynamic behavior of the weft density.

The Hanji treated with citric acid as crosslinking agent was prepared to improve wet dimensional stability and wet-strength. To improve dyeability for direct and reactive dyes, various concentrations of chitosan were added in crosslinking process. The wet dimensional stability and wet-strength of crosslinked Hanji were improved by citric acid addition, whereas the folding endurance significantly decreased. As the concentration of citric acid increased, K/S values of the crosslinked Hanji for berberin increased, but those direct and reactive dyes decreased. However, the dye adsorption for direct dye and reactive dye were improved by chitosan addition.
