Transferring flock printing can pre-prepare different kinds of transferring flocking pattern paper by the consumers different interests, and then put the paper on the fabric which need to transfer. After the high temperature and high pressure, the pattern of the paper can be transferred to the fabric.
The transferring flocking paper is the key of the production. This paper need to be coated with several different kinds of adhesives which are three main of adhesives: flocking adhesives, printing adhesive and transferring adhesives.
The role of flocking adhesive is to make fluffs temporary stay in base paper with proper density. When the flocked printing is transferred on the fabric through the high temperature and high pressure, the base paper and the fluffs will be divided. After the transferring, the surface of the fluffs should not have any adhesive. The suitable flocking adhesives are cellulose derivatives, natural rubber, synthetic polymer, etc.
Printing adhesive is soluble and is requested that it is must easy to make suitable viscosity for washing and printing more easily and with the good extensibility, soft feeling. The natural or synthetic latex can be used as printing adhesive.
The transferring adhesive is used to make the patterns of flocking paper transfer to the fabric in a heating conditions. When the fabric and transferring adhesive get together in heating condition, the transferring adhesive will soften and melt, and then it will combine with fabric firmly. Polyester, nylon, PE and other hot melt powder can be used as a transfer adhesives.
Transferring flocking printing is flocking the fluffs to the paper with flocked adhesive under the role of electrostatic field, and then put the printing adhesive on the fuzzy side of the paper and dust powders of thermosol. After removing the part of thermosol powders which are pasted, the flocking transfer paper is completed.
Flocking and transferring the patterns on paper can depend on the ironing machine (the type of floret can be used household electric iron). The temperature, time and pressure of press the pattern relate with the choice of thermosol powders. Generally, the heating temperature is about 80 to 170 , the pressure is 0.001 to 0.05 Mpa, the time is about 10-40 seconds. After the cooling, take away the bottom paper of flocking transferring, the flocked fabric or the printed leather will appear the flocking pattern with strong stereo feeling.
4.The methods of perspective network printing
Firstly, add the dye to the flocking pulp, and also using the network printing method print the colors on the base fabric, and then flock the colorless fluffs on the base fabric. Because the colorless fluffs is with the low color covering ability, the people can still see the different colors of the base fabric. This method is a unique style.
Process:
Making network model, adjusting printing ink----- network printing and add the colors----- electrostatic flocking----- baking -----arranging-----finished products
Technical note:
(1) Select the fluffs with being transparent, no variegation, being short and being thin.
(2) Select the base fabric in white and with structure sparse and transparent organization.
(3) If add many colors, when print the last color, the colored slurry will become dry and be solidify. That will difficult to flocking. General using two color is easier to flock.
