12) What are the different ways of Textile Quality Control?

• Spectrophotometer: It is used to check the color of the fabric
• CCP ( Crucial Control Point): It is used to check raw material, stitch strength and fabric durability
• Quality Check by industrial governing body: In U.S.A, this body is known as Association for Contract Textiles (ACT). It often imposes standard for textile quality control
• Use of UltraViolet: The fabric is exposed to ultraviolet rays that simulate the sun’s ray to check its durability.

13) Explain how polyester is made?

Polyester is a pure synthetic material made from ethylene; it is derived from petroleum residue. It is prepared in four basic forms filament, staple, tow and fiberfill.

19) Explain what is Tufting?

Tufting is a type of method for textile weaving, which is done by pushing extra yarn into a fabric. In this process, many needles simultaneously punch the fabric at pre-determined distance for extruding the fibers. Tufting is usually done on carpets, blankets and upholstery.

20) How non-woven fabrics are made?

The non-woven fabrics are made by interlocking or bonding of fibers through mechanical, chemical, thermal or solvent means. Different types of fabric are used for nonwovens like wool, cotton, polyester, acrylic, etc.

• Stock dyeing
• Top dyeing
• Yarn dyeing
• Piece dyeing
• Garment dyeing
• Dope dyeing

22) How electrostatic printing works for printing textiles?

In electrostatic printing a dye resin mixture is used, this mixture is spread on a screen bearing the design and then the fabric is passed into an electrostatic field under the screen. By effect of electro-static field, this dye resin mixture is pulled through the pattern area on the fabric.

23) Explain what is Batik Dyeing process?

Batik Dyeing process based on the principle of resisting dyeing process. In this technique, wax is used to design on the fabric and then immersed into a dye, and excluding wax parts the fabric will absorb the color.
