(*)Optionals: Softener (1-2%), Antifoaming (0.2-0.3%) and Antimigration (0.5-1%).
Water is added to the container, and with the agitator working, add the Binding, the Emultex, the Ammoniac and finally the Concentrate 98/2. Mix well all these products with water until they completely homogenize (this mixing operation can take from 10 to 30 minutes, according to the Agitator-Emulsifier power). Then add the white spirits but very slowly, so that each part of added oil of turpentine is incorporated to the water and the other additives. You must never add in a sudden way, because if not the oil of turpentine would remain floating in the container and this would make its mixing more difficult. This procedure may take from 10 to 30 minutes. The final paste pH must be between 8 and 9.
AQUEOUS CONCENTRATE: It is used in the same way, but it does not require white spirits adding at the end because we start with 80-85% of water at the beginning of the formulation. This thickener may also be used in pastes with oil of turpentine, but as it has high yielding it is used from 1.5 to 2% only.
FLOPRINT 150A and 150N Thickeners: They are breakthrough technology thickeners (Inverse Emulsion) high performance (1 to 1.3%). The 150A (acid) does not contain ammoniac, hence, it must be added while preparing the paste (see 2.2). The 150N (neutralized) already has ammoniac.
FLOPRINT 160 LCN: Similar to 150N but it has incorporated an antimigration special additive. This additive improves definition and avoids color migration when printing on mixture garments.
FLOPRINT 180 BRN: Similar to 160 LCN but has improved resistance to electrolytes and faster evaporation oils avoiding dripping in the dryer
FLOPRINT “170R” thickener: synthetic thickener to be used with Reactive, Disperse, Acid and Cationic Dyes (it is necessary to use 2% to 4%, depending on the dye type).
2.3-BINDER "BT", MTV, "XL2833", "RV25", "CATALYTIC" and "SOFT CATALYTIC":
The Binders "BT" and “MTV” fix the color in the fabric at 150º C for 5 minutes.
The Binder "RV25" is similar but with higher solids concentration than the "BT", and with softer touch. The "XL2833" has very good resistance to dry friction (besides the wet friction). The Binders "CATALYTIC" and "SOFT CATALYTIC" allow the suppression of garments baking (cotton 100% and without dressing) reticulating the color to the fabric in 72 hours. But in synthetic fabrics (100% or mixtures), heat must always be applied, even with CATALYTIC BINDER.
2.4-SINTEFIX:
Fixer for mixed synthetic fabrics (with Nylon, Polyester, Streech, Lycra, etc.) In order to react it must be baked (it is not catalytic). It is used from 10 to 20 gr/kg of stamping pastes. The following must be considered:
• The excess of Sintefix causes color bleeding.
• The pastes prepared with Sintefix last from 1to 2 days (then they cut).
• This product exposed to low temperatures (winter) turns into gel ; in order to melt it, heat it double boiler at 40º C.
• Since it is a very reactive fixe, its has a limited life (4 to 6 months); and once turned into gel, it might be unrecoverable.
2.5-CATALYZER:
Concentrate solution to add to the stamping paste when the oven temperatures do not reach 150º C (but not lower than 130º C). Use from 1 to 2%. The excess of catalyzer cuts the pastes and melts them. This additive can be used some times to reduce the viscosity of the pastes.
2.6-FLUIDIFIER:
It fluidizes those too thick pastes, to obtain higher penetration in the fabrics. It can be also added in small amounts (small drops) over the same Schablon when pastes are becoming very thick (hard) for the stamper.
2.7-THICKENER:
To thicken the stamping paste (it is used from 0.5 to 1.5%). It reacts with a minimum amount of Ammoniac (alkaline medium), which must be previously added to the paste to be thickened.
2.8-SOFTENERS:
To soften the stamping (touch), they are used at 2% maximum. The excess of this product delays the drying, hence, it must be polymerized at 150º C from 6 to 7 minutes. There are two types : SUAVITEX and SDE (Conventional mineral oils based) and AK5000 (Silicone based oils).
2.9-COMBOPRINT:
Multipurpose additive for the formulation of screen printing pastes that ofers most of the additives used in the traditional formula All-In-One Product!
The main advantages of COMBOPRINT are:
• Improves wash fastness
• Improves rub fastness
• Improves definition avoiding migration in synthetic or mixture garments
• Improves softness
• Improves the dipersion and mixture of all the components of the paste avoiding the screen blockings
• Improves the paste reology
• Makes the screen cleaning easier.
• Acts a foam supressor
• Reduces the amount of thickener needed
2.10-TABLE ADHESIVE ("ADHETEX") and TABLE PLASTIFIER:
ADHETEX adhesive is for stamping table, to fix the garments to the former. In new tables apply in pure state, and in used tables dilute one part of ADHETEX into two parts of water.
Also 3 types of spray adhesives for manual or automatic machine palets: UNITAC F (dual, cold-warm), HOLD TIGHT (cold spay), and DRY WEB (spider-like, for thick fabrics).
The Plastifier, also called TABLE IMPERMEABILIZER, is used in new coarse cotton cloth tables before applying the Adhetex.
2.11-WATERBASED FLOCK ADHESIVE:
Paste prepared for flocking in the garment. It works well with rayon flock and not so well with the nylon one. To make the "flock" (velvet or shammy leather effect), the adhesive must be stamped and then the fuzz must be scattered. Then, in an electrostatic charged machine, they stand, and finally must be polymerized at 150º C, 5 minutes.
2.12-PRILAC H-8:
Main raw material to prepare Adhesive for Flock.
2.13-ANTI-FOAM H10:
Concentrate solution to eliminate the foam formed while preparing Print and/or the stamping pastes.
It works in very low ratios (0.2 to 0.3%).
2.14-PENETRANT TEX:
It is an additive that provides higher hydrophility to the fibers of those fabrics to be stamped, allowing the better ink penetration, it is used from 1 to 2% over the stamping bases.
2.15-DRYING DELAYER:
It is an additive to delay the pastes dry-off time, when the temperature is above 25 to 30º C. Use from 1 to 3% over the Stamping Bases.
2.16-REFIXING SOLUTION:
When stamps are lack of fastness at washing, this solution must be applied with "spray" over them. Then let it aerate until complete dry and finally apply heat with ironing (160 ºC for 2 minutes).
2.17-AMMONIA:
Product that works in minimum amounts (0.4 to 0.5%) with the thickener. It also gives alkalinity (PH range: 8-8.5) while preparing the source paste (Print) see formulations PRINT L SOFT and CATALYTIC.
2.18- ANTIMIGRATION and "EMULTEX with ANTIMIGRATION":
Additives to avoid color moving (bleeding) in fabrics with these problems. It is mainly used for printing bases formulated with Print (base for clear backgrounds) and they are used from 0.5 to 1%. The "Emultex with Antimigration" is a mixture of Emulsifier with Antibleeding.
2.19-SILK for SCHABLONS (SCREENS):
It is provided Multifilament Silk Nº 38 and Nº 45, in 150 centimeters wide. Also Monofilament Silk Nº 27T, 43T, 48T, 54T, 61T, 77T, 90T, 100T and 120T (the last 3 ones are yellow colored)
2.20- PHOTOEMULSION, HARDENER, SMP RECOVERER and RECOVERER GEL (ready to use)
They are accessories for making of stamping molds (Schablons). The photoemulsion comes with its respective sensibilizer (separated) and it is traded in two types: "Bichromate" (Vortexol Bichromate Emulsion) or "Diazo" (Vortexol Diazo, Emulsion M, Universal Emulsion L, and ULANO 925WR, TZ and 569).
The Hardener can be applied the finished screen to get a longer life of the emultion of the Schblons.
SMP powder is a concentrated salt (dilute 100 g in 5 liters of water) used to recover unlaqued, nor catalized stamping molds.
The RECOVERER GEL is a Ready To Use product to apply on both sides of the screen that has to be recovered. Let it work for 30 min. and then remove with powerwasher.
2.21- DISCHARGE:
It can take place in some dyed cotton fabrics with certain corrosive dyes. To this aim, first try with a drop of concentrated sodium hypochlorite on the fabric, and watch the corroded background of the fabric. If it remains white, decoloration can be made.
a) Discharge with sodium hypochlorite :
The "Print to Decolorate" is used to discharge without color, mixing 70% of this and 30% concentrated sodium hypochlorite. It is stamped and let it aerate until maximum decoloration, then iron or bake to block the discharge and evaporate remaining substances. The "Paste Decolortex" is used to discharge and dye at the same time the fabric background in a single operation, mix 70% Paste Decolortex (because the Binder is incorporated), 25% Concentrated Hypochlorite, 4% Pigment Tex and 1% Antimigration, it is stamped and let it aerate until discharge (appearance of the color at the fabric background), then polymerize at 150º C, 5 minutes or iron (160º C, 2 minutes). The Pastes with concentrated Hypochlorite degrade in a few hours, reason why they must be prepared at the moment to be used.
On the other hand, the Sodium Hypochlorite must not be exposed to the light (store in dark bottles) to avoid the loss of its active substance.
NOTE: Always let the stamped fabric aerate well before you polymerize it in the oven.
b) Discharge with Corrosive Powder (for Cotton):
It is used 90% "CORROSIVE PASTE" and 10% "CORROSIVE POWDER". To the mixture, add 4% Pigment Tex. It must be baked at 140º C, 4 minutes or ironed 45 seconds at 160º C.
For hard discharging fabrics "CORROSIVE PASTE WITH CARRIER" (at 90%) can be used and it can also be added 10% CORROSIVE POWDER.
Consider that the pastes prepared are to be used in the day, then they decompose (they lose the corrosive power).
c) discharge with Corrosive Powder (for Blue Jean):
For "semicdischarges", the first method with Sodium Hypochlorite can be used , but the background will remain partially faded. For total discharge 90% Corrosive Paste is used and 10% especial corrosive powder for "Jeans". It is used to bleach the fabric background (reason why no color is added). After stamping let it aerate well and iron or bake (the stamping will remain brown). Then a solution must be prepared with hot water at 80º C with 10 g/liter of Metha Sodium Bisulphyte, and immerse the stamped jean for 2 minutes. Finally rinse thoroughly with cold water and dry. The stamping will remain completely white.
NOTE: Always let the stamped fabric aerate well before you polymerize it in the oven.
d) Devoré (Poly-Cotton):
For special Polyester-Cotton fabrics, DEVORE PASTE and POWDER are provided. To be mixed at the moment to be used, then are stamped and let to dry. Polymerize for 8 minutes at 150 ºC to get the toasting (devoré) on the cotton. Later, the cotton is eliminated by washing with hot water.
e) Odourless discharge:
To discharge cotton fabrics dyed with certain corrodible colorants. It’s provided in two components that should be mixed before being used. The way of mixing is: 94% of corrosive TDO paste and 6% of odourless corrosive TDO powder.
After printing, heat must be applied. A hot-air industrial pistol or an oven may be used.
NOTE: It is not recommended to add pigment to this paste due to its elevated pH. This makes fastness washability of the pigment decrease.
f) Plasticharge Base, Discharge Base y Discharge White:
Waterbased Discharge bases. They all have a pleasant aroma that counteracts with the corrosive powder smell.
They give softer touch than Corrosive Paste.
Plasticharge is used to discharge without color with maximum softeness.
Discharge is used to discharge with color (40 gr/Kg) because it has binder incorporated.
Discharge white is used to obtain white discharged prints or pastel tones.
The ammount of corrosive powder to be used is between 6-10% in all 3 cases.
2.22- SCHABLON CLEANERS (XILOL, LIMPIAMAX and WASH 8020) and CILINDER CLEANER:
They are cleaning products to remove the adhered products (polymerized) in the silk of the Schablons (screen) after many days of use. Both XILOL and LIMPIAMAX contain aggressive solvents, that is why it is convenient to handle them with gloves and glasses, in well ventilated places or using breathing mask and filter.
Apply only on the silk (with cloth, sponge or brush), to avoid the removal of non desired zones of the lacquered Schablon.
WASH 8020 has the same application but is ecological and has a pleasant citric smell.
The CILINDER CLEANER is a special solvent to clean rotary screen cilinders.
2.23- POXIPOR:
It can be used to solve two frequent problems:
a) "Antipilling" Agent : If the fabric to be stamped usually forms "fuzz" on the stamping after some washings ("pilling"), add 5 g/Kg (at the time to be used) to Print Catalytic or Soft Catalytic or Print L Soft with the color. After 24 to 72 hours (in the case of the Catalytic) the fabric will stop forming fuzz (wornout effect after the washing). The same immediately after ironing or baking with Print L Soft.
b) Synthetic Fabrics: In case of solidity lack at washing (wet friction) in 100% synthetic fabrics (nylon, lycra, polyester, cirié, polyamide, etc.) add Print 20 g/Kg Poxipor (at the moment to be used).
The additive (Poxipor) contacting the paste has a useful life of 24 to 48 hours, then it loses its effect, for this reason it must be added Poxipor again to the paste in order to reactivate it.
IMPORTANT NOTE: Handle this additive with glasses, gloves and breathing protector with adequate filter, because it causes irritation in skin contact.
2.24- POLYVINILIC ALCOHOL and FLOLINE SIZE P:
Polyvinilic alcohol in destined to prepare “Table” adhesive, used to stamp with automatic machines (Rotary and Plane).
FLOLINE SIZE P powder is for also to prepare “Table” adhesive for automatic machines, but it has stronger adherent power .
2.25- SPECIAL PRODUCTS:
a) FLOLINE SIZE P y FLOSIZE BJ, HS y UF: Synthetic powders for gluing.
b) ANTICRACK AGENT: Additive to avoid cracks during dying process (use 5 to 10 g/liter).
c) FIXER 45CLV: High concentration fixer for dying process where direct, reactive, and sulfured dyes are applied (use 1 to 4 g/liter)
d) DISPERSANT Nº8: High concentration dispersing for dying process where direct, reactive, and sulfured dyes are applied (use 1 to 2 g/liter)
e) FLOLUX P017: Additive to get better color strength (up to 30%) and color matching in “foulars machines” tinting (used at 10 g/kg in the paste).
