Abstract
Przedmiotem zgłoszenia jest sposób wykańczania dzianin bawełnianych, w którym zabarwioną lub zadrukowaną dzianinę poddaje się powlekaniu substancją nadającą dzianinie właściwości hydrofobowe, znamienny tym, że: prowadzi się powlekanie w reaktorze (210) za pomocą wału obrotowego (212) z ryflowaną powierzchnią, osadzonego w komorze reaktora (213) i częściowo zanurzonego w ciekłej kąpieli (211) wodnego roztworu zawierającego: od 3 do 10% wag. winylotrimetoksysilanu jako związku czynnego; od 40 do 92% wag. acetonu; od 0,01 do 0,05% wag. kwasu octowego; od 5 do 50% wag. wody. Dzianinę (221) przeprowadza się przez reaktor (210) powyżej lustra cieczy (217), opasaną stroną zewnętrzną na wale obrotowym (212), w układzie współbieżnym i powleka się dzianinę (221) od strony zewnętrznej, przy czym kąt opasania alfa wału obrotowego (212) przez dzianinę (221) wynosi od 20 st. do 45 st., przy czym oś obrotu wału (216) przebiega wzdłużnie, powyżej lustra cieczy (217), w odległości od lustra cieczy (h) wynoszącej od jednej trzeciej do dwóch trzecich promienia wału; a następnie dzianinę suszy się w temperaturze od 100 do 150°C. Następnie poddaje się dzianinę obróbce plazmowej od strony spodniej, poddając powierzchnię dzianiny wyładowaniom plazmowym o mocy w zakresie od 1000 do 2500 W/m2min, usuwając od strony spodniej substancję nadającą dzianinie właściwości hydrofobowe i przywracając hydrofilowe właściwości dzianiny.The subject of the application is a method of finishing cotton knitwear, in which colored or printed knitwear is coated with a substance that gives the knitted fabric hydrophobic properties, characterized in that: coating is carried out in the reactor (210) using a rotary shaft (212) with a checkered surface, embedded in the chamber reactor (213) and partially submerged in a liquid bath (211) of an aqueous solution containing: from 3 to 10 wt. vinyltrimethoxysilane as the active compound; from 40 to 92 wt. acetone; from 0.01 to 0.05% by weight acetic acid; from 5 to 50% by weight water. The knit (221) is passed through the reactor (210) above the liquid surface (217), the outer side is banded on the rotary shaft (212), in a co-rotating system, and the knitwear (221) is coated on the outer side, the alpha angle of the rotational shaft ( 212) through knitwear (221) is from 20 to 45 degrees, with the shaft rotation axis (216) running longitudinally, above the liquid surface (217), at a distance from the liquid surface (h) of one third to two thirds shaft radius; and then the knitwear is dried at a temperature of 100 to 150 ° C. Then the fabric is subjected to plasma treatment on the underside, subjecting the surface of the fabric to plasma discharges in the range of 1000 to 2500 W / m2min, removing the substance from the underside that gives the fabric its hydrophobic properties and restores the hydrophilic properties of the fabric.
