| 3.7 Winding Section
It is the last section of yarn manufacturing process where auto cone machines are installed and take an input material from ring spinning section as a yarn bobbin and give a yarn on paper cone after passing detecting instrument as an output. In winding section, there are lot of heads in auto cone machines use to wound the yarn from ring bobbin yarn to paper cone yarn. Now days, there are some companies to manufacturing these machines and Savio company is one of them which produce a fully automatic machine for spinning industries. In quality point of view, it is a very good machine and has also very low maintenance cost. Winding department plays an important role in the production and quality of yarn and causes direct effect on them. The yarn which made in ring section is not finish yarn and can’t sell to customer. After making the yarn in ring process, auto cone section made it more even yarn by passing through the optical sensor which is installed in different heads of machine. The yarn which is obtained from winding section is able to sell the customers. [46] Fig. 9 Diagram of Winding Department IV. D EFECTS IN Y ARN M ANUFACTURING P ROCESS & ITS P REVENTION 4.1 Blow Room Blow room is the initial step for yarn manufacturing process in spinning mill. In blow room cotton bales are opened and cotton is transfer from different number of machines with the help of air flow. This chapter clears the main objectives of blow room such as opening, cleaning and mixing and also describes the technical point regarding to quality point of view. Here also describes the defects which affect the yarn quality and preventive action to cover these defects according to quality standard. There is lot of things in this department which is described below: Fig. 10 Diagram of blowroom tải về 1.28 Mb. Chia sẻ với bạn bè của bạn:
