AVCO-PUFF 300

THREE DIMENSIONAL PRINTING EFFECT
AVCOPUFF 300 is a ready made printing paste used to produce three dimensional patterns on textile fabrics, with good dry and wet fastness properties.

SPECIFICATION:

Appearance Slightly tan coloured viscous paste.
Chemical nature Aqueous dispersion of special synthetic polymers, binders and thickeners.
Compatibility Can be pigmented with organic and inorganic pigments used in textile printing. Is not compatible with strong acid, alkalis, solvents and with cationic products.
Film properties When drying the wet material at temperature of 120-140°C, the film thickness multiplies with a factor of 6-12, and produces a flexible, three-dimensional plastic film, with acceptable wash and rubbing fastness properties.
Ionicity Anionic
pH (as is) 7 ± 1
Solubility Can be further dispersed in cold water.
Storage
  1. Sensitive to frost.
  2. Do not store in direct sun and in hot places.
  3. Stable for at least 6 months.
Viscosity 70 – 80 dPa.s ( Haake viscotester).

PROPERTIES & USES:

  1. AVCOPUFF 300 is applicable onto most types of fabrics.
  2. AVCOPUFF 300 can be tinted with regular aqueous pigment dispersions.
  3. The product is ready made for printing. No additional binders or thickeners are
    needed.
  4. Good wash and rubbing fastness of the printed fabric.
  5. Can be printed together with regular pigment pastes in the same pattern, but
    laboratory test should be run to receive optimum “puff” effect together with
    acceptable fastness of the printed fabric.
  6. Can be used with all types of printing machines.

APPLICATION:

  1. Use AVCOPUFF 300 paste as is. If viscosity is too low add 1-5 g/kg AVCO-CLEAR NP and homogenize. If viscosity is too high add 5-10% of cold water and stir well.
  2. If a tinted print is needed add AVCOLOR PIGMENT to obtain the desired colour.
  3. To produce white effect add 5-10% AVCOLOR WHITE TD.
  4. Print and dry at 130-140÷C for 2-3 minutes. The degree of loft is dependent upon the type of fabric, the amount of product applied and drying conditions. Very absorbent fabrics will produce poor results.
  5. Best results will be obtained by applying heavy load of AVCOPUFF 300 on the surface of the fabric.
  6. Above recommendations are good starting points, but may have to be adjusted by each individual printer depending upon type of fabric, printing machine and drying oven.
  7. After printing and drying, a final curing at 140-150°C for 2-3 minutes can improve fastness properties.
  8. Use coarse screens for big blotches. It is possible to print with fine mesh screens to produce fine patterns.
  9. Fabric should not be rolled hot when it is getting out of the printing machine or the curing oven, but should be folded loose.
  10. To minimize running problems, and to prevent drying of material in the screens, the following procedure should be kept:
    • Use coarse screens. Screens should be properly cleaned before printing.
    • In case of rotary screens. Wrap a wet cloth around the screen during stoppage, or wash and clean before starting printing again.
  11. If a finishing step is needed, it can be done, but the loft of the printed areas should be checked in a pre-trial.
  12. Fabrics printed with AVCOPUFF 300 can be ironed at low temperature, as recommended for synthetic fabrics. Ironing on reverse side of the fabric is preferred.
