Parameter of finishing process in knit dyeing

[...]... MeGraw-Hill International, New York, America Abstract: We have tried to present all types of finishing processes Most of the finishing processes are not conduct in Bangladesh In our country function finishing process is done mostly Aesthetic finishing are more expensive than functional We tried hard to give accurate parameter and solve the fault of finishing process That’s how we can develop finishing process. .. constant support it could not have been possible • In our project we came up mainly with different kinds of knit finishing parameter & development in different machines In the project of us we included the each machines in the finishing lines, their working mechanism, their technical data, machine specification, ways of controlling different important parameters, faults and remedies •We express our heartiest...
