Flocking machine process introduction:
1. Sizing: According to the properties of the product and the substrate, choose adhesives with different properties. Waterborne polyurethane adhesives or acrylic adhesives can be selected according to different materials and properties. Such as rubber, plastic, steel, glass, wood, etc. as the substrate, the main consideration is the adhesion fastness. The material used for clothing should not only consider the washing fastness, but also consider the soft hand feeling, air permeability and moisture permeability. If the viscosity is too small, the villi on the implant may be inclined, and if the viscosity is too high, the implant depth will be hindered and the strength will be reduced. If the coating amount is large, the hand feel will be poor and the drying time will be prolonged; if the coating amount is small, the rubbing fastness will be reduced. Adjust the proper viscosity and coating amount to ensure the quality of the flock.
2. Flocking: There are four main flocking methods: lifting type, falling type, side planting type and top-bottom planting type. Lifting type: the fluff enters the electric field on the conveyor belt, and under the action of static electricity, the fluff rises from bottom to top and is inserted into the adhesive in the adhesive coating of the substrate. The lifting method is on the top, and the falling method is on the bottom. The lifting method requires two conveying devices, namely, the conveying of the processed object and the conveying of the fluff. The structure is complex, and the tension is large during transmission. If the fabric is not strong, it is difficult to process. For discontinuous production, the lifting method is better, because the fluff is partially implanted in the adhesive under the action of the electrostatic field, the excess fluff will fall naturally, and the flocking surface will be less floating. The falling law adds a velvet suction device to absorb the floating velvet on the suede surface. At present, most flocking machines adopt the falling type. The side planting method is suitable for flocking block objects, and the lifting and falling method is suitable for flocking linear objects.
3. Thermosetting: After flocking, heat treatment is required to make the fluff, the adhesive and the substrate firmly bonded. There are generally two stages: pre-baking and baking, depending on the type of adhesive. There are also many heating methods. Usually, the hot air circulation method is better, which can not only reach the crosslinking temperature of the adhesive, but also make the water in the adhesive detached as soon as possible. The drying temperature should also pay attention to the properties of the substrate to prevent the material from deforming at higher temperatures. The heat treatment is done in an oven, and its quality has a great influence on the flocking fastness. In order to ensure the temperature and time of heat treatment, if the vehicle speed is fast, the length of the oven should be lengthened appropriately.
4. Bristles: Although the floating lint is absorbed after flocking, there are still residual fluff in the gap. Generally, a brush is used to clean the bristles in the way of moving against the movement of the substrate. There is also a combination of mechanical beating, blowing, etc. for treatment, the effect is better. If no post-finishing is required, the finished product can be obtained after brushing the bristles.
