Weft density (PPI) Weft density indicates the number of weft yarn present in unit space. Picks per inch (PPI) is one of the units to express weft density. In general, the higher the picks per inch, the finer the fabric is. Drape and Crimp are the distinctive mechanical properties of fabric.

2021年7月10日 · These characteristics will affect not only how easy the fabrics are to handle, but how they drape, if they are prone to wrinkle, and how durable they are. We will discuss the woven fabrics quality parameters which alludes diverse test method of fabric, for example, EPI and PPI, GSM, crimp%, appearance, hand feel, quality and so forth. CHAPTER 1

Jane’s Master Sett Chart encompasses more than 40 years of weaving experience, trial & error and extensive sampling with many of our yarns. This chart is an invaluable treasure trove of weaving advice. All Combinations and Setts for 8/2 cotton above would apply. Fabulous. A little firmer than above, but still drapey. Slightly firmer than above.

2009年8月16日 · EPI and PPI affects the compactness of the fabric. It is also known as thread count or cloth count. Thread counts range from as low as 20 threads per inch as used in tobacco cloth to as high as 350 threads per inch, found in type writer ribbon fabrics. Normally EPI and PPI of a fabric are described as EPI×PPI.

2009年11月5日 · The static and dynamic drape behaviour of polyester-fibre shingosen fabrics was investigated precisely and analyzed by using the new mechanical parameters of the dynamic drapability of fabrics ...

Fabric testing is very essential to judge the desire quality of apparel products. For this different types of fabric properties testing are used worldwide such as EPI & PPI, Drape testing, GSM, Fiber identification etc. Fabric is a cloth produced by weaving various cotton, nylon, wool, silk, or other threads together.

There is a significant effect of crimp% on fabric drape for different weave structures, counts and weft densities. Key words: Woven fabric, Drape, Crimp INTRODUCTION

This paper reports a comparative analysis of two modeling methodologies for the prediction of drape coefficient of handloom cotton fabrics. Four primary fabric constructional parameters, namely ends per inch, picks per inch, warp count, weft count
