Presentation Transcript
Blending Raw materials used in spinning mill are always inhomogeneous in their characteristics. In part, this is inevitable owing to the different cultivation conditions of natural fibres and different production conditions for synthetic fibres. It is done in order to influence the end product and the process. Blending is performed mainly in order to: a. Give the required characteristics to the end product, for example, blending of synthetic fibres with natural fibres produces the desired easy-care character. b. Compensate for variations in the characteristics of the raw materials. c. Hold down raw material cost d. Influence favorably the behavior of the raw material during processing e. Achieve effects by varying color, fibre characteristics and so on.
Types of blending Bale Mixing: before the blow room i. Flock blending: within the blow room ii. iii. Lap blending: using scutchers iv. Web blending: at ribbon lap machine or blending at drawframe Sliver blending: at drawframe, the sliver-lap machine, or at the comber v. vi. Fibre blending: at card or the OE spinning machine vii. Roving blending: at the ring spinning machine
