Total Textile Process at a Glance

2.
 Finishing is a general term which usually refers to treatment on textile fabrics
after dyeing or printing.
 It increase life and durability of the fabric.
By finishing we can maintain fabric shape and size.
Finishing accentuate or inhibiti some characteristic of fabric.
Impart new characteristic or properties.
Finishes may be done by chemically or mechanically.
To get good finished quality we should maintain machine parameter or proper
chemical recipe.
We can improve finished product quality by developing machine parameter or
create new and appropriate chemical recipe.

•To improve the appearance of the fabric.
•To improve the feel of the fabric by softening, stiffening, etc.
•To cover faults in the original fabric.
•To increase weight of the cloth.
•Special properties required for particular uses .

After dyeing process from the dyeing machine then the fabrics are ready for de-watering. This is the
process to remove the water from the fabrics partially by squeezing.

To remove the water from the fabric.
To control the width of the fabric.
To control the length of the fabric.
To control the spirality of the fabric.
To control the over feeding system.
To increase the softness of the fabric.
To remove the crease mark of the fabric.

•Softening treatment is one of the most important chemical after treatments in the textile industry.
•By softening treatment textile can achieve not only soft handle but also:
Some smoothness.
More flexibility.
Drape and Pliability.
Antistatic properties.
Luster.
Soft handle.
Types of
softeners:

14.
Advantages:
•Resins have a profound effect on and cause changes in the hand (feel), drapability and physical
characteristics of textiles.
•They add stiffness to fabrics and are thus used as stiffening agents or to create a firm hand.
•Yarns in fabric will be stabilized and will resist shrinkage in laundering.
•This finish imparts luster to the cotton.
•Increases cotton strength by nearly 25% and improves dye affinity.
•It is a method of thickening woollen material to make it more water-resistant

15.
•Nanotechnology is an umbrella term covering a wide range of technologies concerned with
structures and processes on the nanometric scale.
•. Nanotechnology deals with the science and technology at dimensions of roughly 1 to 100
nanometers (1 Billion Nanotechnology = 1metre), although 100 nanometers presently is the
practically attainable dimension for textile products and applications.
•The Nanotechnology can be used in engineering desired textiles attributes, such as fabric
softness, namely, water repellency, fire retardancy, antimicrobial resistance etc in fibers,
yarns and fabrics.
•Enhancement of textile materials by nanotechnology is expected to become a trillion dollar
industry in the next decade, with tremendous economic and ecology benefits.
•With the advent of nanotechnology, a new area has developed in the realm of textile
finishing.

16.
Antimicrobial Finish:
• It is a well-known fact that the growth of bacteria and microorganisms in food or water is
prevented hen stored in silver vessels due to its antibacterial properties.
• The antibacterial properties of silver are now scientifically recognized.
• Silver ions have been spectrum of antimicrobial activities.
• The method of producing durable silver containing antimicrobial finish is to encapsulate silver
compound or nano particle with a fiber reactive polymer like poly (styrene-maleric anhydride).
• Products which are commonly applied are brominated phenols, quaternary ammonium
compounds, organo-silver and tin compounds, which can be applied as solutions or
dispersions.
• They can also be incorporated in a polymeric film deposited on the surface to achieve
controlled release.
• The rays in the wavelength region of 150 to 400nm are known as ultraviolet radiations.
•ultraviolet absorber finish of a fabric is present that absorbs ultraviolet radiation and blocks
its transmission through a fabric to the skin.
•Metal oxides like ZnO as UV-blocker are more stable when compared to organic UV-
blocking agents.
•Hence, nano ZnO will really enhance the UV-blocking property due to their increase
surface area and intense absorption in the UV region.

Conclusion
•We all have tried our level best in accomplishing the project.
•Lack of presentation time we skip some topic which we include ours
presentation book.
•We are greatly thankful to the management and staffs of the companies namely
“GMS Composite Knitting IND. Ltd.”, “ Raiyan Knit Composite Ltd ” .Without
their 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 thanks to our project supervisor and honorable
teacher, Najmul Ehsan, Lecturer of the Department of Textile Engineering for his
logical guidelines, constant inspirations, necessary instructions and proper
supervision

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 and give more
production. Due to limitation our knowledge we did not all finishing processes.
We think that our internship and project paper based on finishing will increase
our knowledge in many sides.
