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 […]
Knitting Faults in fabric
Knitting Faults in fabric : Weft fabric faults, Causes and Remedies 1. Hole Mark Causes: ❶ Holes are the results of yarn breakage or yarn cracks. ❷ During loop formation the yarn breaks in the rejoin of the needle hook. ❸ If the yarn count is not correct on regarding structure, gauge, course and density. ❹ Badly […]
Flat Knitting Technology
Flat Knitting Technology INTRODUCTION : The fabric which is produced by the machine is usually weft knitted fabric. Flat fabric will be produced. In the flat knitting machine needles are kept stationary and the cam will move along the width of the machine ( vice versa to circular knitting machine). It was first invented […]
Knitting | Knitting Types | Advantages and Disadvantages of Knitting | Properties of Knitting
Knitting Knitting is the second most popular technique of fabric or garment formation by inter-looping one or one set of yarns. Continuous length of yarn is converted into vertically intermeshed loops either by hand or by machine. The most important parameter of a knitted fabric is loop length which can be varied during knitting by changing machine […]
Shaded Twill Weave and Stepped Twill Weave
Shaded twill is formed shade effect on the surface of the fabric. The shade effect is created by the combination some thick to thin twills and thin to thick twills. Stepped twill is formed by steeping a continuous twill and keeping the direction of twill line same or opposite.
Elongated Twill Weave and Combined Twill Weave
Elongated twill is constructed by advancing the points of intersection two or more threads in one direction and one thread in the other direction.On the other hand combined twill is formed by combination two regular twill and arranging them alternately with each others.
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
