Description

REACTIVE INKJET BASE is a ready-to-use product specifically for preparation of cotton fabrics for inkjet printing. It offers optimal viscosity and concentration of auxiliary products and requires no further additions.
It offers decidedly superior colour yield and definition compared to ordinary preparations containing sodium alginate.
If used to prepare viscose fabrics, about 80 g/kg urea should be added, shaking thoroughly. Or use REACTIVE REA/V INKJET BASE, a product specially formulated for this type of fibre.

Directions for use

REACTIVE INKJET BASE is ready to use and may be used as-is, with no special instructions. If the product is stored for prolonged periods of time, shake it before using.

REACRYL RE

Features

Features
appearance slightly viscous liquid
Colour
yellowish
Composition
natural polymer, organic and inorganic salts
Uses
REACRYL RE is formulated specifically for preparing fabrics for digital textile printing with reactive dyes.
Storage
store at a temperature between +5°C and +35°C for up to 6 months.

Description

This product may be used on fabric substrates suitable for digital printing with reactive dyes, such as cotton, viscose and linen. It can be used to obtain brilliant prints with excellent colour yield and thread hold.

Directions for use

To make REACRYL RE more stable, the alkaline part permitting fixing of reactive dye has been removed. For correct application, follow these instructions: for example, to mix a 1000 l bath, add 40 kg sodium bicarbonate to 160 litres of purified water; add 800 kg REACRYL RE to the resulting solution and then soak in a foulard bath. It is sufficient to dry it, as there is no need for polymerisation. You may then proceed with digital printing operations.
