Textilelab.blogspot.com (visit) Southeast University Department Of Textile Engineering I/A 251,252 Tejgaon Dhaka Bangladesh Prepared By : “Study An Effective And Consistent Finishing Effect Through Stabilizing Dryer on Knit Fabric“ Total Textile Process at a Glance Introduction  Here we’ve presented the project on the topic of finishing of textile. We’ve tried our best to include all the important term related to textile finishing. I hope we could know some important parameter and suggestion on textile finishing. Objectives of this Project:  The objects of this project is to study an effective and consistent finishing effects through stabilizing dryer on knit fabric.  To study about assistant device that improve quality, effect and production.  To improve crease mark, hand feel, appearance, smoothness, shrinkages etc Knit fabric Finishing  The term finishing, in a broad sense it covers all the processes of making the fabric good looking, good hand feeling, luster and of course for buyer requirement. It is done after dying and before delivery to market. Various types of parameters are controlled during finishing section considering buyer requirement. The term also includes bleaching, dyeing, mercerizing etc. But normally the term is restricted to the final stage in the sequence of treatment of Knit fabrics after bleaching and dyeing. However, fabrics which are neither bleached nor dyed are also finished. Objects of finishing: The aim of finishing is to render textile goods fit for their purpose or end use. Besides that, finishing can be done for achieving the following purposes-  a) To improve fabric attractiveness. - By modification of fabric appearance(optical brightening), -By altering fabric handle (Softening, Stiffening) -Control of fabric dimension (Sanforising, Compacting)  b) To improve service ability. -Protection of fabric (Flame proofing, Water proofing) -Improved performance (Water repellency, Raising) -Easy care properties (Resin finish, Crease recovery) Types of finishing:  1) Chemical finishing: Softener, Biopolishing, Enzyme, UV Protection, Anticreaase, Silicon Finish etc.  2) Mechanical finishing: Shrinkage, Raising and Shearing, Finishing effects:  Easy - care  Crease recovery.  Dimensional stability.  Good abrasion resistance.  Improved tear strength.  Good sew ability  Soft or stiff hand feel  Shine or luster [...]...Sequence of finishing Tube fabric finishing Hydro-extractor ↓ De-watering ↓ Dryer ↓ Tubular compactor Open fabric finishing Hydro-extractor ↓ Slitting & De-watering ↓ Dryer ↓ Stenter ↓ Open Compactor Observation of Different Finishing m/c: Slitting machine: This machine is used to make the tube fabric into open form Machine parts and functions:  Rotary blade: To cut the... fabric padder pressure and speed will be maximum In the case of high GSM S/J fabric then padder pressure and speed will be minimum In case of Lycra single jersey fabric, speed & padder pressure will be minimum Before Compactor After Compactor Finishing effect of Compactor m/c Before Compactor Finishing       Small amount of water is contained Crease mark Luster medium Hand feel medium GSM isn’t...    Overfeed roller Expander Blanket Steam sprayers Cylinder Teflon covers        Special note on compactor finishing: In case of light color padder pressure should be low Otherwise shade will be lighter If the padder is not clean, then line mark can appear in the fabric Fabric dia, extension, speed, compaction & overfeed will vary depending on the fabric type and finishing requirements In...
