Printing Process Flow Chart Of 100% Synthetic Fabric

Synthetic fabric printing is easier than natural fabric printing. We know that, printing flow chart depends on the characteristics of fiber. In cotton printing, it requires to pre-treat the fabric before printing but in case of synthetic fabric it not essential to pre-treat the fabric because synthetic fabric does not contain impurities like natural fiber.

Printing Process Flow Chart Of 100% Synthetic Fabric: There are various types of synthetic fiber. Printing process for all the fiber is not same. The printing process of nylon, polyester or acrylic fiber varies from one from another. It also depends on the dyes and pigment types. Anyhow, I have written about the basic printing process flow chart for 100% synthetic fabric.

Fabric from weaving section



Jet Dyeing







Folding or Rolling


Synthetic fibers are produced from the polymerization of different monomer. After printing, finishing is done for add some properties. So, it requires to aware about the printing sequence.

So, print your synthetic fabric by suitable dyes.

Polyester | Physical And Chemical Properties Of Polyester

Polyester is a very important manmade fiber. Polyester is produced with a long chain synthetic polymer with ester. Polyester is produced by melt spinning process. Here, I have given physical and chemical properties of polyester fiber which is important to know.

Physical Properties of Polyester: Like cotton or other fiber, polyester fiber consists of some important physical properties. Important physical properties of polyester are given below.

  1. Tenacity: 5 – 7 gm/den
  2. Elongation at break: 15 – 30%
  3. Elastic modulus: 90
  4. Elasticity: Good
  5. Moisture Regain (MR%): 0.40%
  6. Specific Gravity: 1.38
  7. Melting point: 2500C
  8. Volumetric Swelling: None
  9. Ability to protest friction: Excellent
  10. Color: White
  11. Light reflection ability: Good
  12. Lusture: Bright

Chemical Properties of Polyester: Various types of chemical properties of polyester fiber are given below:

  1. Acids: Good resistance to acids in cold condition. But polyester degrades by H2SO4 at high temperature.
  2. Basic: Good resistance to basic in cold condition but Strong NaOH dissolves polyester in boiling.
  3. Effect of bleaching: Polyester does not affected by bleaching process.
  4. Organic solvent: Organic solvent does not affect on polyester fiber.
  5. Protection ability against mildew: Good
  6. Protection ability against insects: Good
  7. Dyes: Polyester could be dye with disperse, azoic color and some pigments.
  8. Solvents of polyester: Following are the solvents of polyester:
    • Chlorinated hydrocarbon.
    • F3COOH
    • Phenol (in hot condition)

So, during processing of polyester, we have to consider the physical and chemical properties of polyester.

Process Flow Chart Of Synthetic Fiber Production | Techniques Involved With Man made Fiber Production

Synthetic fiber is that which is made from different types of polymers. It is not cultivated as the natural fiber. Manmade fiber is produced from the reaction between different types of monomers. By the polymerization process, a long chain of polymer is produced. Then filament is produced by the various spinning process. Various types of synthetic fiber are available in the market Day by day its availability increases for its cheap price. But there has lots of bad effect of man made fiber to the environment.

Now I will show you how manmade fiber is produced?

Process Flow Chart of Synthetic Fiber Production: The process flow chart of various synthetic fibers is differing from one to another but basic process is same. Here, I have given a flow chart of synthetic fiber production which is same for all. It is the basic sequence of man made fiber production.

Raw Materials / monomers


Drawing and Stretching



Heat Setting

Finished Filaments

Technical operation in man made fiber production: Various types of technical operations are involved with the synthetic fiber production. They are as follow:

  1. Preparation of spinning fluid from solid polymers or directly from monomers.
  2. Spinning that is extrusion of the spinning fluid through small dies (Spinnerets). Extension of the emerging fluid jets into filaments of revived, thickness, accompanied by solidification of the obtained filaments on a suitable mechanical device
  3. Mechanical, thermal and chemical treatment is applied on filaments to improve their characteristics and performance.

So, it is not so easy to produce manmade fiber from the monomers. One should apply above techniques for synthetic fiber production.
