Friction calendering line speed differential role in the operation of the friction roller surface speed on the calender and fabric in the machine. custom made flags for cars Three roller friction calendering machine, the friction roller is generally higher than the following two roller speeding 30% ~ 300% friction to the polished surface of the fabric, Promotional Wind Flags fabric interwoven pore pressure did not, and as one (such as paper like), you can give the fabric a strong aurora, the cloth is very smooth feel stiff, similar to the glossy, often referred to as the shiny finishing. Fabric calendering should control the fabric moisture content was 10% to 15%.
(2) electro-optical finishing the electro-optical machine is engraved with the surface of a certain angle and density custom made flags for cars of diagonal lines, hard steel roller and a second flexible soft roll. Within the hard roll can be heated, pressure fabric rolling in the heat and some moisture conditions, the pressure on the fabric surface parallel to the neat twill money, thus the reflection of incident light to produce rules, silky high-gloss surface. Wang satin fabric finishing mostly through the electro-optical finishing. Electro-optical hard roller surface slash density varies due to the thickness of the yarn and fine yarn fabric is preferable to a larger density, the most common 8 to 10 / mm slash. Colored Feather Flags The sculptured lines of the diagonal with the twist of yarn in the fabric surface, custom made flags for cars consistent, and depending on the variety of processed fabric requirements vary, otherwise it will affect the luster and strength of the fabric.
Corrugated finishing and electro-optical finishing similar corrugated hard roll surface engraved with the pattern of positive lines, soft roll is engraved with the hard roller corresponding to the Yin grain pattern both match with each other. Fabrics by engraved with the corresponding pattern of hard and soft roller, wet, heat, custom made flags for cars pressure, resulting in the concave-convex pattern. Light corrugated machine, also known as emboss machine, hard roll with copper rollers for , soft roll nitrile rubber rollers (active roller), emboss the Etched shallow hard roll, soft roll there is no obvious corresponding Yin pattern, emboss pressure smaller, lighter pattern on the fabric bump degree a sense of hidden flowers.
Regardless of calendering, electro-optical and corrugated finishing, Discount Custom Car Flags simply use mechanical processing, the effect can not be sustained, once the water washing, shiny patterns and so on will disappear. And resin finishing joint processing, you can get the durability of calendering, electro-optical and corrugated finishing.
Foreign a multifunctional calender when used according to the collation requirements, as long as the exchange of the main hard roll, you can use of a machine, calendering, friction calendering, electro-optical, corrugated and other functions, the machine corresponding covers an area of more small, easy to use.
(B) brightening finishing
Fabric after bleaching, often with traces of yellow-brown shade, Made China Car Flags not easy to do a white, often use fabric whitening methods to increase the white feeling. Whitening method, there are two: one is on the blue-whitening method, is about to make a small amount of blue or purple dye or paint the fabric coloring, the use of the complementary role of the pigment color, slightly biased towards the fabric of the reflected light violet light, the fabric looks white increase, but decrease in brightness, slightly dark sense in recent years has been rarely used alone only for the fluorescent whitening shade adjustment. Garden House Flags Another is fluorescent whitening France, fluorescent whitening agent is dissolved in water was colorless, its chemical structure and dyes, dye fiber, fluorescent brighteners are colorless, but dyed fiber in the UV excitation, issued by the blue-violet fluorescence visible to the naked eye, Buy Cheap Garden Flags trace tan and the fabric itself reflected light mixing
