Abstract
Vynález sa týká spósobu úpravy celofánu prěd termickou potlačou. Podstata vynálezu spočívá v tom, že sa celofánová folia uvedie bezprostredne před termickou potlačou do styku s alkoholom, éterom alebo/a ketónom o teplote varu 34 °C až 200 °C alebo/a vodou, s výhodou do styku s metanolom alebo acetónom.The invention relates to a method of treating cellophane before thermal printing. The essence of the invention is that the cellophane film is brought into contact with alcohol, ether and/or ketone with a boiling temperature of 34°C to 200°C or/or water, preferably with methanol or acetone, immediately before thermal printing.
Description
Vynález sa týká sposobu úpravy surověj celofánovej fólie najmá pre účely termickej potlače podía AO 198 636.The present invention relates to a process for treating raw cellophane film, in particular for the purpose of thermal printing according to AO 198 636.
Dosial' sa takýmto sposobom celofán záměrně neupravoval. V štruktúre celofánovej fólie sú plastifikátory glycerín a propylénglýkol o konštantnej koncentrácii a premenlivé množstvo vody.So far, cellophane has not been intentionally modified in this manner. In the cellophane film structure, the plasticizers are glycerin and propylene glycol at a constant concentration and varying amounts of water.
Teraz bolo nove zisteno, že celofán je možné před termickou potlačou výhodné upravit spósobom podía vynálezu tak, že sa celofánová folia uvedie bezproetredne před termickou potlačou do styku s alkoholom, éterom alebo/a iketónom o teplote varu 34 °C až 200 °C alebo/a vodou, s výhodou do styku s metanolom alebo acetónom.It has now been found that cellophane can be advantageously treated prior to thermal printing in accordance with the invention by contacting the cellophane film with an alcohol, an ether and / or an icone having a boiling point of 34 ° C to 200 ° C immediately before the thermal printing. and water, preferably in contact with methanol or acetone.
Podstata vynálezu spočívá v tom, že pósobením telesa vyhriateho na 200 °C až 300 °C počas niekolko stotín sekundy na celofán upravený týmto postupoim, dójde ku splyneniu tekutin alebo rozkladu tepelne nestálých látok obsiahnutých v štruktúre celofánu a týiůlto spósobom ku vytvoreniu bielej farby povrchu celofánu.SUMMARY OF THE INVENTION The invention is based on the fact that by subjecting a body heated to between 200 ° C and 300 ° C for a few hundredths of a second to regenerate cellophane treated by this process, liquids or decomposition of thermally unstable substances contained in the cellophane structure occur. .
Výhoda spósobu podía vynálezu je, že zavedenie do štruktúry celofánovej fólie iných látok s nižšou teplotou varu, s menším vyparným teplom alebo teplotou rozkladu alko majú v celofáne postupom výroby obsiahnuté plastifikátory, umožňuje vytvořit postupem termickej potlače pri nižších teplotách viac esteticky biely povrch celofánu v súvislej ploché alebo diskrétnych vzoroch.An advantage of the method according to the invention is that the incorporation into the cellophane film structure of other lower boiling, lower evaporating or alcohol decomposition temperatures have plasticizers included in the cellophane by the manufacturing process, making it possible to produce a more aesthetically white cellophane surface in continuous flat or discrete patterns.
PříkladExample
Surová celofánová folia sa máča v roztoku alkoholov, éterov, ketóndv, vody alebo ich zmesi s výhodou metanolu alebo acetónu za normálnych podmienok minimálně 15 minút. V druhom případe postupu móžeme tieto rozpúšťadla kantinuálne naniesť v tenkej rovnomernej vrstvě na povrch celofánu tesne pre navíjením na zásobný válec. Týmto spósobom dójde ku migrácii molekúl vyššie spomenutých roztokov do štruktúry celofánovej fólie. Takto upravený celofán sa musí spracovať termickou potlačou skór, akoiby došlo ku samovolnému odpareniu týchto látok do vzduchu.The crude cellophane film is soaked in a solution of alcohols, ethers, ketones, water or a mixture thereof, preferably methanol or acetone under normal conditions for at least 15 minutes. In the second case of the process, these solvents can be cantinally applied in a thin uniform layer to the surface of the cellophane just after being wound onto a supply roll. In this way, the molecules of the above-mentioned solutions migrate into the cellophane film structure. Cellophane treated in this way must be subjected to a thermal suppression of the scores as they spontaneously evaporate into the air.
