Learning Special Fabric Printing Method || BURN-OUT PRINTING

We have discussed about the basic methods of fabric printing that are widely applied in Textile sector.

If you missed that session, you may go through the following link: Basic Printing Methods

Today we will discuss about the special Printing method termed as Burn-Out Printing.

Burn-out Printing

 Burn out printing is the production of a pattern on a fabric by printing with a substance that destroys one or more of the fibre types present.

 A paste containing chemicals capable of destroying one of the fibre components is used in this process.

 It is also called devore printing.

Basic Principle of Burn-out Printing

 It entails the use of a print paste containing an agent capable of dissolving/destroying the fabric in the printed areas during subsequent processing.

 The effect can be employed alone or in conjunction with printed head-colors.

 The extent to which ‘burn out’ is required must be controlled so that the physical strength & stability of the fabrics are not unduly impaired.

 Any fabric can be subjected if a reagent is used which can be controlled during processing & which is not harmful to operatives or machinery.

Burn-out Printing of PC Fabric

  1. In burn out printing, cellulose portion of PC fabric is removed with the desired properties by using 70-75% strong H2SO4.

  2. Burn out printing may be carried out in following two methods-
    a. By jigger
    b. By Padding mangle

  3. Recipe:
    H2SO4 - 70% in strength
    Urea -10gm/L (Padding mangle)
    Time - 45 min (Jigger), 120 min (Padding mangle)
    Temp - Room temperature
    M:L - 1:15

  4. After burnout, fabric is washed thoroughly to remove degraded cellulose & remaining H2SO4.

  5. Then it is neutralized with Soda ash & bleached with H2O2.

  6. The fabric is washed again and dried.

Advantages of Burn-out Printing

 Burn out printing is used to make fashion dresses and decorative purposes.

 No special or costly machine is required.

 This style was originally used on cotton to give novel dress fabric effect.

Disadvantages of Burn-out Printing

 If the process not properly controlled the whole fabric will be damaged.

 May impair tensile strength & stability of fabric.

 It can't be corrected.

 The highly concentrated chemicals are harmful to operatory & machinery.

 Only blended fabrics can be printed.
