Introduction

SEQENS develops custom solutions and ingredients for the most demanding industries such as aeronautic, construction, cosmetics, electronics, automotive and textile.

Cross-Linking agents

In this purpose, SEQENS offers cross-linking agents, TEXTENS GM 192 and TEXTENS TA 135, enabling the reduction of textile fibers’ fibrillation.

In the wet state, the water penetrates inside the fibrillar bundles, resulting fiber swelling and breakage of hydrogen bonds. This leads to fibril splitting and subsequent exposure of the fibrils onto the fiber surface giving the finished fabric a frosty appearance.

Reducing fibrillation of textile fibers allow high wet abrasion resistance and a modified pore structure of the fiber for better dye fixation.

TEXTENS properties

Can cross-link with fibers under alkaline conditions before or after the fabric has been dyed
Maintain the good physical properties of the fiber together with a good dye affinity
The fabric produced can be processed on most dyeing machines
Give to the fabric produced a good performance in subsequent washing
The cross-linked fiber has an enhanced dye uptake that gives more economical dyestuff costs and deep coloration
Less unfixed color remains to be removed, both reducing the water consumption in washing off and the color loading in the dyehouse effluent
TEXTENS can also be used for other applications such as strength paper agent and as an ingredient in the formulation of solder resist inks

Textens TA 135

Hexahydro-1,3,5-tris(1-oxoallyl)-1,3,5-triazine

Hexahydro-1,3,5-tris(1-oxoallyl)-1,3,5-triazine as TEXTENS TA 135 is specifically dedicated to LYOCELL fiber. It can also be used for other applications such as paper strengthening agent and component in the formulation of solder resist inks.

Textens GM 192

2-sodiumhydroxy-4,6-dichloro-1,3,5- triazine

2-sodiumhydroxy-4,6-dichloro-1,3,5- triazine as TEXTENS GM 192 is generally used for cellulosic fiber as well as for gelatin hardening in the photographic industry.

Our TEXTENS ingredients are manufactured through trimerization in France at Ecovadis Gold Certified production sites and are available at the highest levels of purity and low insoluble residues. Triazines manufacturing processes have been optimized to be strongly repeatable, safe and cost effective thanks to automatization, good process control and raw materials recycling. Trimerization enables the preparation of a wide range of 6 atoms aromatics heterocycles where 3 carbons have been replaced by 3 nitrogens also called triazines. Trimerization is taking place in acidic conditions where a formaldehyde derivative is reacting with a carbonitrile in the presence of a solvent

Another process can also be used to produce chlorinated triazines. Starting from cyanuryle chloride, an oxidation is taking place to replace one or several chlorines by other functional groups such as ketones or amines.
