By Computer Aided Design System (CAD) for yarn dyed fabrics, fabric patterns are displayed quickly and realistically on the screen and printed onto the color printer, so as to confirm and examine the final design of woven fabrics.
However there still are several problems in the precise image reproduction of woven fabrics, which the designer plan to weave.
In this study, the several types of fabrics with difficulties were imulated exactly by he use of 3D inference method, yarn surface database and image addition technique.

Basic mechanical properties and hand of fabric were pursued through a finishing process of the fabric woven from New Zealand Crossbred wool yarns by objective evaluation method using KES-FB system and following results were obtained. The fabric sampled from off loom showed hard and became harder after singeing stage intensile, bending, shearing and compressional properties. However, the fabric became soft greatly by the next crabbing-scouring stages. The effect of the subsequent dyeing, drying, cropping, paper pressing and blowing (decatizing) stages on the mechanical properties were small. Although primary hand values and total hand value also changed remarkably by the singeing stage, they became moderate and high rank respectively by the next crabbing-scouring stage. The large change by the singeing stage was due to the cinders which remained between fibers and they were removed completely by the next crabbing-scouring stage. Surface characteristics did not correspond well with surface “prickliness”.

A new sizing method is tried with water-soluble vinylon filaments. In this method a warp yarn is passed through the hole of the bobbin winded vinylon filaments, therefore the vinylon filaments unwinding from the bobbin wrap around the warp yarn. The warp is then passed between two rollers coated with warm water in order to complete sizing.
this sizing treats at the temperature from 60°C to 95°C and the speed from 10 m/min to 30 m/min with running yarn twisting 10 turns/m. The warp yarn obtained by the method is evaluated by means of tensile property, an abrasion resistance and an osmotic ratio. This novel process has the potential of reducing the cost of sizing compared with a twisting method.

Recently, the training wear has come to be used widely and synthetic fibers such as nylon, polyester are the most common materials for the training wear. Consequently, as man putting on a training wear falls down or slips on the floor in the gymnasium, man burns its legs or arms due to the heat generated at the contact surfaces between the wear and the floor. The temperature of wear surface reaches 500 degree, then, has been reported.
In this study, we observed the molten state of fabrics mainly used for trainingwear by using the measuring machine built as a trial, and evaluated the molten state with the mean values of surface roghness measured by KES system. The results obtained are as follows.
1) The mean values of the surface roughness after friction test decrease compared to the state before friction test in both of untreated and treated fabrics, therefore, the mean values of the surface roughness measured by KES system are available for the evaluation of the molten state of fabrics.
2) As the treated fabrics has low mean values comparing with the untreated fabricsafter friction test, the effect of anti-frictional melt finishings is clearly noticed.
3) The breaking elongation of fabrics decreases after friction test.
4) The mean values of the surface roughness after friction test decreaes the collision velocity increases and the collision angle become small.
5) The molten state of fabrics is influenced considerably by the presence of the anti-slip finishing of the floor.
