Ring Doubling Frame: Parts, Specifications, Gearing Diagram & Calculation

Experiment Name: Study on ring doubling frame Spindle speed, front roller delivery. Twist, twist constant. Objectives: To combine two or more single threads into one. To insert sufficient amount of twist for holding the yarns. To increase strength, smoothness and luster. To reduce hairiness. To make sewing thread. To wind a suitable bobbin. Main parts: Creel stand and creel Front roller Yarn…

Calculation of Twist, Twist Constant of Ring Frame

Name of the experiment: Calculation of twist, twist constant of the ring frame. Twist: Twist is inserted to the staple yarn to hold the constituent fibers together, thus giving enough strength to the yarn and also producing a continuous length of yarn. Twist is imparted to staple yarns to induce lateral forces. Friction created by these forces acts to control fiber slippage in a strand under…

Calculation of Draft, Draft Constant of Ring Frame

Name of the experiment: Calculation of draft, draft constant and draft in each zone of the ring frame. Introduction: Ring spinning is one of the most used method of yarn production even though a number of more highly productive systems were commercially developed during the twentieth century. The main reasons for this are its flexibility in spinning a range of fiber types, its capability of…

Ring Frame: Gearing Diagram, Calculation of Spindle Speed & Front Roller Speed

Experiment name: Study on the gearing diagram, calculation of spindle speed and front roller speed of the ring frame. Ring frame: The ring frame is normally fed with roving from a large bobbin, and delivers yarn to a smaller one. The ring frame consists of a large number of spindles. One traveler and spindle co-operate with a bobbin, to twist and wind the yarn from a drafting system as shown in…

Material Passage Diagram of Ring Frame or Ring Spinning Machine

Experiment name: Study on the material passage of ring frame or ring spinning machine. Ring frame: The ring frame consists of a roller drafting unit, a yarn guide (lappet), a ring and traveler assembly, and a bobbin mounted on a spindle (driven by a tape). The ring frame performs basic operations such as Attenuation (drafting) of the roving to the required yarn count Imparting cohesion to the…

Cotton Yarn Spinning Process Step by Step

Cotton Yarn Spinning Process Step by Step Harshani Wijendra Sri Lanka Institute of Textile and Apparel Technology (SLITA) Email: [email protected]   What is Spinning? A Yarn is usually of substantial length and of small cross section. In the cross section of a yarn there are usually a multiple number of Staple fibers (short fibers) or Filaments (long fibers) of unlimited length. Yarn…
