PVC浸塑工艺

有哪位朋友熟悉PVC浸塑工艺的？

具体包括这种工艺的应用领域、生产工艺、优缺点、成本等方面。

This is what I found from WikiPedia.

Plastisol is a suspension of PVC particles in a plasticizer; it flows as a liquid and can be poured into a heated mold. When heated to around 177 degrees, the plastic and plasticizer mutually dissolve each other. On cooling the mold below 60 degrees C, a flexible, permanently plasticized product results.[1]

Plastisol is a type of ink used for silkscreen printing on to textiles. Plastisols are the most commonly used inks for printing designs on to garments, and are particularly useful for printing opaque graphics on dark fabrics.

Advantages
Plastisol inks are not water-soluble. Because the ink is made up of PVC particles suspended in a plasticizing emulsion, the ink will not dry if left in the screen for extended periods of time. Because of the convenience of not needing to wash a screen after printing is done, printers using plastisol inks can do so without a nearby source of running water.

Plastisol inks are recommended for printing on colored fabric. On lighter fabric, plastisol is extremely opaque and can retain a bright image for many years, if cared for.

Disadvantages
Plastisol inks will not dry, and need to be cured as a result. Curing the inks can be done with a flash dryer, or more inexpensively, any home oven. Most plastisols need to reach a temperature of about 160 degress celsius (350 Fahrenheit) before being fully cured.

Plastisol tends to sit on top of the threads instead of soaking into them, giving the print a raised, plasticized texture. Other inks can produce a softer feel.
