This research surveys the differences of fabric mechanical properties according to the different looms and the fabric positions with relation to warp and weft weaving tensions on the Picanol and Omega looms respectively. For this purpose, the grey fabrics woven in the previous paper are processed in dyeing and finishing processes, and the processing shrinkages are measured on each processes such as dryer, scouring, pre-set, dyeing and final-set using the fabric density and width. The mechanical properties of the finished fabrics are measured and discussed with relation to the warp and weft weaving tensions of the two looms and the variations of the fabric mechanical properties according to the fabric positions are also discussed. In addition, the fabric thickness according to the fabric positions such as right, left selvedges and center of the fabrics is also measured and discussed with the characteristics of the Picanol and Omega looms.

A method for the design of a disk cam with a remote follower is presented. ADAMS software is utilized for the design process. The whole process is applied for the design of a cam profile to be used in a tappet shedding device of a shuttle loom. First the desired motion of the remote follower, the hearld frame in this case, is determined to improve the characteristic of a certain weaving process. Next, the desired displacement data is input to the ADAMS software and the cam profile is obtained as an output. To test the validity of the proposed method, designed cams were actually manufactured and implemented on a experimental loom. And with the help of potentiometer type displacement transducers, the motion of the remote followers were actually recorded. And the result was sufficient to prove the validity of the presented method.

In this paper, we implemented a loom component to be placed in a window and a looms management system which is able to connect database and to process various queries. The implemented system has aggregate query p개cessing functions for the loom components existing in the selected area by the mouse and it also has high level query processing functions represented with chart and pivot table; it can be used as a decision support system. The proposed system can detect temporal or persistent problems of the looms. Therefore it can be used to raise the productivity and to reduce the cost in textile companies by coping with the situation properly.

In this study a computer-aided textile pattern design system is implemented and a control methodology of a dobby motion is studied. The described system allows the user to design various weave patterns through graphic editor and to simulate weaving by displaying the dummy weaving process on the monitor. In addition, if the yarn colors are specified it is also possible to analyze color weaves. Thus it can replace effectively a conventional. design tool, a design paper. The main features of the system are to design weave patterns, to show weaving effect, and to make lifting plan for the dobby motion control. In dobby motion control, the mechanical. control method conventionally used is not adequate for the loom which is linked with the computer-aided textile pattern design system, so an electromagnetic control method is proposed.

This research surveys the mechanical properties of worsted fabrics for garment according to the loom characteristics and fabric positions with relation to the warp and weft weaving tensions on the projectile and air-jet looms, which is previously surveyed in the 1st paper. For this purpose, the grey fabrics are processed in dyeing and finishing processes. The mechanical properties of the finished fabrics are measured and discussed with relation to the warp and weft weaving tensions of projectile and air-jet looms and the variations of the fabric mechanical properties according to the fabric positions are also surveyed for investigating the homogeneity of the tailorability and fabric hand.

This study surveys the warp and weft tension differences among 3 types of rapier looms and analyses the mechanical properties of worsted fabrics for garment with relation of these looms characteristics using KES-FB system. Raper is divided by two parts. In the 1st paper, the worsted fabric is woven as 5 harness satin weave using 1/40 Nm sirofil worsted warp yam and 1/30 Nm worsted weft yam by rapier looms such as FAST-R, THEMA-11-E and PICANOL-GTX respectively. The weavability is also analysed by measuring warp tension variation according to the warp position and weft tension of 3 kinds of looms. The relationship between shed amount and the warp tension is surveyed, and the relationship between end breaks and warp and weft tensions is also discussed.

In this study, the fabrics were woven with worsted grams of Nm 2/72 and the structure of 5 harness satin on rapier and air-jet loom with different weft insertion mechanism and then fabrics were finished in the same processes. Also the physical properties were measured with KES-FB system and discussed with the characteristics of looms for comparing the difference of physical properties of the worsted fabrics which were woven with two different looms under the same structure. Pot shearing and compression properties, then showed similar behavior and the fabric finishing processes were seemed to affect much more than the difference of the loom types. For the surface roughness, the rapier fabrics showed higher irregularity than the air-jet fabrics.

This research surveys the differences of fabric mechanical properties with the different looms and the fabric positions according to the warp and weft yarn tensions on the Vamatex and Omega-Panter looms respectively. For this purpose, the grey fabrics woven by PET filament using two test looms are dyed and finished. The processing shrinkages are measured on each processes such as dryer, scouring, pre-set, dyeing and final-set using the fabric density and width. The mechanical properties of the finished fabrics are measured and discussed with relation to the warp and weft yarn tensions of the two looms and the fabric positions. In addition, the fabric thickness according to the fabric positions such as right, left selvedges and center of the fabrics is also measured and discussed with the characteristics of the Vamatex and Omega-Panter looms.
