### Gearing Calculation of Tappet Loom

Gearing Calculation of Tappet Loom Fig : Gearing Calculation Of Tappet Loom Here, motor is the main power source. The machine pulley is connected with motor pulley by V belt. So, here motor pulley driver. That means, machine pulley is driven by motor pulley. Crank shaft is connected with machine pulley. The R.P.M. of machine […]

### INTRODUCTION TO TAPPET SHEDDING

INTRODUCTION TO TAPPET SHEDDING 1.What is shedding? Ans: It is the first primary motion. Shedding is the process of dividing the warp yarns into two layers. Note: To separate the warp thread into two layers – One layer is raised and the other layer is lowered. 2.What is shed? Ans: The passage tunnel or space […]

### Introduction to Desizing of Warp Yarns

Introduction to Sizing Introduction to Desizing of Warp Yarns Desizing : Desizing is the process in which the size applied to the warp yarn before weaving is removed to facilitate the penetration of dyes and chemicals in the subsequent wet processing operations. In the process of desizing, not only sizing agents, but also some natural […]

### Introduction to Sizing of warp yarns

Introduction to Desizing of Warp Yarns Introduction to Sizing of Warp Yarns Textile Sizing : The process of applying a protective adhesive coating upon the yarn surface is called textile sizing. This is the most important operation to attain maximum weaving efficiency specially for blended & filament yarns.  Different types of sizing are used like […]

### Basic Element of Woven Design (Drafting, Lifting & Denting Plan)

The process of drawing the warp yarn through the eye of heald frames according to design is called drafting, and the plan which indicates how drafting needs to be done is called drafting plan. It also denotes the number of heald shaft required for a given weave repeat

### Zig-zag and Herringbone Twill Weave

Zigzag twill are those in which the direction of twill is frequently reversed at suitable intervals either across the width or along the length. Herringbone twill are those in which the direction of twill is frequently reversed at suitable intervals either across the width or along the length but not as zig-zag twill and weft yarns floating condition is reversed of the previous yarn.

### Diamond Design | Diaper Design

Diamond design is constructed on the principle of zig-zag twill.Pointed draft is used to make diamond design.Diaper design is constructed on the principle of herringbone twill.Straight or broken draft is used to make diamond design.

### Broken and Rearranged Twill

Broken twill is formed by breaking the twill line of basic twill. Normally straight draft is used to produce this weave. Rearranged twill is produced by the rearrangement or transposition of the original order of the threads in the regular basic twill.

### Derivatives of Plain Weave

There are two types of derivatives : Rib and Matt. In rib weave, it produces rib or cord effect in warp/weft direction. Used as grosgrain cloth, mattress cloth,hair cords, blankets etc. Matt is constructed by extending the plain weave both vertically and horizontally. Matt weave finds extensive uses for a great variety of fabrics such as dress materials, shirtings, sail cloth, duck cloth etc.
