– Into the
Pre-knot finishing joint machine, spray to wet the cloth feeding device, cheap car flags umbrellas heap cloth box, three-roll rubber blanket compression device, blankets dryer composed of sub-classification in the next.
(1) into the fabric devices: suction side, the tension, the composition of the feed roller and cloth-speed detector. The requirements of the fabric into the pre-shrinking machine to cheap car flags keep straight, in order to avoid the flaws such as wrinkles or rolling wrinkle.
(2) to the wet devices: including sprayers, steam box, Discount Car Flags so that a certain amount of water evenly and thoroughly into the fibers and give the fabric plasticity, in order to facilitate pre-indented line. Rate to the wet process, usually 10% to 20% rate to the wet too large or too small is not conducive to pre-shrinking. Piled some time to wet umbrellas box, make the fabric moisture uniform ordinary pre-shrinking finishing machines are used to Made China Car Flags wet the fabric around the chain plate distance of
(3) compression devices: the various types of three-roll rubber blanket pre-shrinking machine, the heart of the pressure roller diameter is 300 ~
(4) blanket dryer: mechanical pre-shrinking machine supplementary drying device can not afford the fabric shrinkage effect, the addition to desiccation, but also the fabric compression wrinkles ironing device, the fabric surface roughness, cheap car flags feel plump, light Optional soft.
Chemical shrink-proof method using chemical methods to reduce the fiber hydrophilic, so that the fiber can not produce a large swelling when wet, so that the fabric does not produce serious shrinkage. Often use the resin finishing agent or crosslinking agent to treat fabric to reduce the fiber hydrophilic. Auto Racing Flags For Sale Cotton fabrics after mechanical pre-shrinking, basically meet the requirements, there are few specialized chemical shrink-proof, cheap car flags but after a while the resin anti-crease finishing get shrinkproof effect.
Third, the appearance of the finishing
Fabric appearance finishing calender finishing, electro-optical finishing, corrugated finishing and bleaching fabric whitening finishing. Enable the fabric appearance after finishing to improve landscaping, such as gloss increase, increased flatness, surface rolled into concave and convex patterns, such as.
(A) calendering finishing
Calendering finishing generally can be divided into ordinary calendering, friction calendering and electro-optical. The role of mechanical stress, temperature, humidity, by means of the plasticity of the fibers, the fabric surface, flatten the yarn flattening in order to improve the luster of the fabric surface and smooth degree.
An ordinary calender finishing on the calender. Calendering machine is mainly composed by the overlap of soft and hard roller, roller number of points ranging from 2 to 10, according to the different finishing requirements to determine the number and arrangement of the soft and hard rollers. Hard roller made of cast iron or steel, smooth surface, the hollow can pass into the steam and other heating, soft roller with cotton or paper meal made of the car flat polished high-pressure compression. Fabric to wear around after rolling point between roller can be hot pressed flat and get shiny. Calendering hard roller heating temperature 😯 ~ 110 ° C, the temperature the higher the gloss stronger, cold-rolled fabric only a smooth surface, Feather Flags For Sale no gloss. More than five roller calendering machine, such as with a group of 6 to 10 sets of cloth guide roller frame, you can choose OK to stack calendering fabrics using multi-layer with each other through the same point of rolling rolling pressure, the yarn round uniform lines clear, like linen luster, and with wearing more layers around the cloth and touch become more soft, so stack calendering can also be used for fabric mechanical soft finish.
