- INTRODUCTION - RESEARCH PLAN	1. Modeling yarn formation processes a) ring spining b) friction spining c) draft process - roll drafting dynamics   constitutive model (elastic term), steady-state dynamics,   transient analysis neglecting inertial effect,   effects of model parameters and process conditions,   stochastic variations in parameters and process conditions,   transient analysis including inertia term,   irregularity control, etx. - gill box   distributed B.C.,   faller speed profile 2. Developing innovative staple yarn manufacturing methods a) application of ring spining :    - hybrid yarn (staple/staple core/sheath yarn)    - commingled yarn (inorganic staple of filament/filament for composite prepreg)    - compact yarn b) application of friction :    - direction control of combed fiber fleece    - commingled yarn (inorganic staple or filament/staple) c) apllication of two-for-one twistion    - pin spinning d) vortex spining with real twisting    - combination of air guided fiber fleece input, open end twisting by air vortex and winding 3. Identification of staple yarn properties and     Development of irregular yarn a) irregularity analysis :    - spectral method, wavelet method, fractal or nonlinear dynamics...    - factors influencing yarn irregularity b) generation of irregular yarn prossessing a certain autocovariance function    - deterministic yarn with irregularity band width c) designing a random yarn and production    - a fully random yarn 4. Weaving technology and process control a) stop marks reduction :    - modeling and simulation, state space model and control b) definition of warp yarn weave-ability by weaving simulator c) optimal tension control of electronic let off/take up system d) thick fabric with 3D-structure e) sparse warp or weft density fabrics for filter f) 3D-shape weaving g) leno weaving h) super wide weaving for construction textiles i) rotationg beat-up device for sparse warp density fabrics 5. Application of futher textile specific technologies a) seamless branch tube (braiding) b) elastic tube (transverse and axial) c) application of knitting technologies as a bonding tool :    - 2D or 3D-structuring the staple fleece, fiber bundle, yarn, and filament of inorganic fibers
