In many printing or flocking processes, the wash fastness will be found after printing. It’s not firm, it will fall off if you rub it with your hands, etc. It’s a headache? First of all, it has a lot to do with the color fastness of the adhesive (solid paste). Good adhesives (solid pastes) have very good color-fixing effects. For example, ZY-907, ZY-807, ZY-607, etc. on the market have very good color-fixing effects.
Some printing friends will still fall off after adding some additives. How should this problem be solved?
It can only mean that you are using ordinary additives. Or some unscrupulous merchants have mixed other solvents into the fixing agent in order to lower prices and increase profits.
A good color fixing agent has the following characteristics: (1) Good color fixing effect and environmental protection
(2) Improve the washing resistance, high temperature resistance and resistance of the fabric coating Stickiness and stain resistance
(3) Adding it to glue printing: it can improve its washing and soaping fastness, improve its water resistance and anti-stickiness, and reduce the migration of dye molecules of chemical fiber fabrics
(4) Adding to the enzyme-washed stone-ground denim glue printing: can increase the adhesion and improve its wear resistance
(5) Adding to the water slurry/bang pulp printing: can Improve its color fastness to wet and dry wiping, water washing, and soaping
(6) It can be used as an anti-adhesive agent in the rayon flower industry. It can be set at high temperatures to prevent adhesion. It can generally improve the performance of water-based systems on non-porous bottoms. adhesion to the material.
Wash. There are many types of printing on printed clothing. Due to its special nature, dry cleaning is generally not allowed. Before washing, zippers should be zipped and zippers, buttons, cords and other accessories should be wrapped to avoid scratches, roughness and peeling on the printed surface due to scratches during the washing process. and other phenomena.
Choose phosphorus-free and bleach-free detergents when washing. Do not use strong alkaline detergents on protein fiber printed clothing to avoid fiber breakage and damage to the printed area. Try to wash by hand instead of machine washing. The water temperature of knitted printed clothing and non-chemical fiber printed clothing cannot exceed 40 degrees Celsius. During the washing process, clothes should be turned over so that the patterned side faces inward. It is forbidden to scrub the pattern with force or use a brush or washboard to avoid causing the rhinestones or glitter to fall off, and the printing to crack or fold. The soaking time should not be too long, only 5 to 6 minutes, to avoid swelling of the cellulose fibers, causing roughness, blistering, and bulging on the printed surface. After washing, press gently to drain the water. Do not wring it out hard or spin dry in the washing machine.
Let dry. During the drying process, turn the clothes over to dry, allowing the patterned side to dry naturally. Avoid exposure to the sun to avoid discoloration of the print and fading of the fabric. If drying is required, silk and cotton products should be kept within 40 degrees Celsius, and do not pull the printed clothing with your hands.
Ironing. If ironing is required, in addition to ironing according to the care temperature, try to use steam ironing, and do not exceed 80 degrees Celsius. Do not iron items containing elastic fibers at high temperatures to avoid damaging the tissue structure of the elastic fibers. Do not iron directly on the pattern. If you need to iron the print, you need to put a layer of fabric over the print.
Storage. Ironed clothes cannot be stuffed into a small space immediately. They should be hung or laid flat to keep the clothes flat.
If the clothes are pilling, use a pill remover to remove them. Do not stick or pull them off, otherwise the fibers will be elongated, pilling will continue, and the printing may be damaged. If you need to stack them, be careful not to place the printed parts close together to prevent them from sticking, causing problems such as blistering, staining, and shedding, which will affect the overall appearance of the garment.
