Printing material Gaoli polyurethane foam pulp is water-soluble printing and dyeing factory used for heat sensitive polyurethane foam pulp, suitable for weaving pure cotton, knitted fabrics, sash cotton, T-shirts and other clothing printing. According to the short-term quenching and tempering treatment, to maintain the three-dimensional pattern growth, with soft touch, strong tensile strength, polyurethane foam after the three-dimensional symmetry and other characteristics. For everyone detailed introduction of the use of polyurethane foam pulp and common problems.
1, because the polyurethane foam pulp itself is not color fastness. Therefore, when making polyurethane foaming clothing printing, suitable printing glue paste mixture should be used. According to the actual effect of polyurethane foam with better ductility and color fastness, the adhesive paste with stronger ductility and color fastness can be mixed with polyurethane foam paste. The common proportion refers to: 30%-40% polyurethane foam paste +60%-70% glue paste and well-proported, and can not be too thin when mixing the paste.
2, choose the appropriate chiffon mesh, all normal application of 80-100 mesh chiffon, but also according to different patterns of different mesh mesh application.
3, clothing printing 2-3 times, slurry must be thoroughly dried (otherwise it will harm the color fastness, height to width ratio, flatness), after 140-150 degrees of furnace baking for 3 minutes or 130-150 degrees pressing for 10-15 seconds. Such as pressing, the working pressure can not be very large, the working pressure can be adjusted to loosen a little.
Polyurethane foam pulp common problems.
1, it is proposed that polyurethane foaming clothing printing can not be used with an iron, the reason: the polyurethane foaming surface ironed out by the iron will not be even. It is suggested that pressing machine and air drying machine have better practical effect.
2. When printing polyurethane foaming clothes, the proportion of polyurethane foaming pulp is too high, and the color fastness will be poor. Proposed polyurethane foam pulp accounted for less, packaging printing frequency put more. It gives better colour fastness.
3, the actual effect of the hair dryer is not good, the reason: polyurethane foam surface polyurethane foam will not be symmetrical. It is suggested that pressing machine and air drying machine have better practical effect.
4, when the actual effect of polyurethane foam pulp height to width ratio is not up to? It is proposed that the proportion of qichao polyurethane foam pulp or polyurethane foam pulp is reduced, and the proportion of the transparent pulp is higher, and the printing is many times.
5. After printing, the cloth will be collected after washing. It is proposed to put less polyurethane foam pulp and try again.
6, polyurethane foaming slurry can not dilute water or thickening emulsifier, otherwise it will harm the actual effect of polyurethane foaming.
