Method for Manufacturing Fabric with High-efficiency and High-precision Flat Screen and Digital Printed Patterns with Energy Saving and Emission-reduction Effect
A method for manufacturing fabric with flat screen and digital printed patterns includes: singeing, pretreatment, flat screen scraping sizing, drying, pattern printing, humidification, steaming treatment, washing, and non-ironing and soft setting. The pretreatment is a biological enzyme pretreatment process including: cloth feeding at 75° C., dipping, scouring and bleaching in a working fluid, heating to 90° C. for treatment of 30 minutes, draining, hot water washing and cold water washing. A shortened process flow can be realized, and the positioned sizing that uses a flat screen to scrape a sizing agent to a pattern position to be digital spray-printed on instead of traditional full-width sizing for sizing and printing, which greatly reduces the amount of sizing agent used, lowers production cost and reduces waste water pollution, and solves problem that the fabric is mottled caused by the application of sizing agent in areas without printed pattern due to full-width sizing.
PROCESSING FLUID, SET OF PROCESSING FLUID AND INK, APPLYING DEVICE, IMAGE FORMING DEVICE, APPLYING METHOD, AND IMAGE FORMING METHOD
A processing fluid contains an alcohol having an amino group and a polyvalent metal salt, wherein the processing fluid is applied to fabric.
SUBLIMATING A SUBLIMATING PRINTING SUBSTANCE
Disclosed is an apparatus to generate heated air to sublimate a sublimating printing substance. The apparatus comprises: a self-regulating heating element; an air retaining device to retain air in the apparatus for heating by the self regulating heating element; and an airflow generating device arranged selectively to urge heated air to leave the retaining device. Also disclosed is a method to sublimate a sublimating printing substance deposited on a printing medium and a system to produce printing content on a printing substrate using a sublimating printing substance.
PRETREATMENT APPARATUS
The present disclosure relates to a pretreatment device capable of increasing a number of media on which a pretreatment can be performed within a fixed period. The pretreatment device includes a platen, a pretreatment portion configured to perform the pretreatment on a medium set on the platen, and a belt configured to convey the platen from a set position to the set position via the pretreatment portion. The medium is placed on the platen at the set position. Thus, since the belt conveys the platen on which the medium is set, the pretreatment device is able to perform the pretreatment on a plurality of the media within the fixed period.
Process for dyeing of textile materials using supercritical fluid
An embodiment herein provides a process for dyeing of textile materials 108 with supercritical fluid. One or more dye materials 102 along with additives (if required) are mixed with at least one suitable solvent 104 to obtain one or more dye solutions 106. A textile material 108 is pre-treated with the one or more dye solutions 106 to obtain a dye coated textile material 110. The dye-coated textile material 110 is exposed to the supercritical fluid 112 in a supercritical fluid dyeing vessel at controlled pressure and temperature. The supercritical fluid 112 solubilizes and diffuses the one or more dye materials 102 inside the surface, pores and capillaries of the textile material 108. The supercritical fluid vessel is then depressurized below supercritical condition to entrap the one or more dye materials 102 in the textile material 108 to obtain a supercritical fluid dyed textile material 114.
Method and apparatus for manufacturing fiber for synthetic hair
A method and apparatus fabricate synthetic hair by mixing a raw material to form a mixed material; sterilizing the mixed material to form a sterilized material; melting the sterilized material to form a melted material; yarning the melted material to form a yarn material; sterilizing the yarn material to form an intermediate sterilized yarn; heating the sterilized yarn to form a heated yarn; and sterilizing the heated yarn to form a final sterilized yarn. Sterilizing of the mixed material, the yarn material, and/or the heated yarn includes: sterilizing using an ultraviolet (UV) lamp. Heating of the sterilized yarn is performed by a heating device selected from a heated roller, a heating plate, a steam jet device, and a hot water reservoir. Alternatively, sterilizing of the heated yarn includes: immersing the heated yarn into an immersion device, which includes an antibacterial solution. The final sterilized yarn forms a synthetic hair.
PRINTHEAD CLEANING
In an example of the disclosure, a cleaning system for a printhead includes a web of material movable in a web direction. The web has a first side for wiping a printhead face. The cleaning system includes a dispensing apparatus to dispense a liquid upon the web. The cleaning system includes a scraper element for scraping liquid from the web and includes a collector element with a trough. The collector element is to cause collection of liquid scraped from the web to collect in the trough. The cleaning system includes a pusher element to push against the second side of the web and thereby cause the first side of the web to wipe the printhead face
Pretreatment device
A guide guides a movement of a platen from a set position P1 at which a recording medium is set on the platen to a press position P3 at which a heat press portion performs heat press operation on the recording medium. A distance from the set position P1 to the press position P3 is longer than a distance from the set position P1 to an application position P2 at which an application portion applies a pretreatment agent onto the recording medium set on the platen.
Digital Printing and Finishing Method For Fabrics And The Like
A method of digital printing and finishing for fabrics is provided. The method includes a step of unwinding a fabric from a first reel. A step of compensating the speeds and of spreading the fabric for its positioning on a conveyor belt provided with supporting elements on which a digital printing step occurs is provided. A step of drying the fabric is provided. A step of winding the fabric onto a second reel is provided. These steps are being executed at corresponding stations arranged in sequence with respect to each other and the fabric passing through them continuously, transversely to the conveyor belt, there being a plurality of bars provided with printing heads which are controlled electronically and synchronized with the movement of the conveyor belt.
Pretreatment device and pretreatment information setting method
A pretreatment device includes a pretreatment portion, a reception portion, a processor and a memory. The pretreatment portion performs a pretreatment on a recording medium. The reception portion receives recording medium information that the recording medium has. The memory stores computer-readable instructions that, when executed by the processor, perform processes including: setting, for the pretreatment portion, pretreatment information relating to the pretreatment, on the basis of the recording medium information received by the reception portion; and causing the pretreatment portion to perform the pretreatment on the basis of the set pretreatment information.
