DE1085492B - Process for improving the grip of organic fiber and film material (A) - Google Patents

Description

GERMAN

It has been found that it is possible to react organic fiber material containing hydroxyl groups to give special properties with very specific triazine compounds.

For the purposes of the invention, fibers made from native cellulose, such as Cotton, linen or cellulose, regenerated cellulose, such as viscose fibers, or fibers made from cellulose derivatives, z. B. cellulose esters, such as acetyl cellulose, or cellulose ethers. The fibers can be in loose form or in the form of Web, such as paper, yarn, woven, knitted or finished textile goods are treated. After the procedure The invention can also treat substances that contain, in addition to organic hydroxyl groups Fibers also other fibers, e.g. B. wool, silk or polyamide fibers. Likewise can Treat foils made of substances containing hydroxyl groups.

Triazine compounds according to the invention have the following formulas:

Here, X means an —NH-, —S- or - 0 bridge, R is an alkyl radical, an aralkyl radical, an alkylaryl radical, an alkylcycloparaffin radical, a cycloparaffinic alkyl radical, an alcohol residue, an amino residue or an alkanolamino residue.

For certain purposes it is also possible to use those triazine compounds in which the group R contains one or more SO ₃ H groups or their salts or one or more COOH groups or their salts. Likewise, you can also use triazine compounds, which in the group R the group

contain. Here, R 'denotes hydrogen or an aliphatic or aromatic radical. Such groups can by treatment with an alkylene

oxide, preferably with ethylene oxide, are introduced.

According to the invention, the method is carried out so

that is preferably treated material to be treated with an aqueous alkaline solution of the triazine compound at a _pH value from 7.5 to 11. The excess solution is then removed and dried at an elevated temperature, preferably at 80 to 130 ^° C.

Fibers which are treated according to the invention are obtained depending on the composition of the X groups and R various valuable properties. In general, an improvement in the hand is effected. When using such triazine derivatives in which R is a hydrophobic radical, the fibers can also be water-repellent will.

When carrying out the process, it is best to start from 0.5 to 10% strength aqueous solutions of the triazine compound. Such triazine compounds which are insoluble or only insignificantly soluble in water are generally out of the question. Suitably the reaction is carried ° / _o aqueous solution having a 1 to. 3 Depending on the triazine compound used, the treatment can be carried out at different temperatures. The aqueous solution contains a dichlorotriazine compound, one can even at room temperature or moderately elevated temperature, preferably at 20 to 40 ⁰ C, working. In solutions of Monochlortriazinverbindungen one turns expediently higher temperatures of 50 to 100 ° C to, preferably from 70 to 90 ⁰ C.

In many cases it is sufficient if the fiber material is impregnated with the solution of the triazine compound, the excess solution is removed and the material is then at an elevated temperature, preferably at 80 to 130 ⁰ C and dried. Often it is also advisable to post-treat the treated material after drying with hot, better still boiling, water and then to dry it again. An alkaline solution can also be used for post-treatment.

Fibrous material treated according to the method of the invention also loses the acquired properties not with repeated washing.

example 1

Cellulose muslin is treated at room temperature with a 2% aqueous solution of a dichlorotriazine derivative obtained by reacting trichlorotriazine with an ethoxylated partial ester of pentaerythritol and stearic acid. The excess solution is squeezed off and dried, the tissue at 80 ⁰ C. Then it was treated by with a boiling 3 ° / _o solution of sodium bicarbonate and dried again at 110 ⁰ C.

The fabric has been given a pleasant, soft feel that is not lost even after repeated washing.

Example 4

Paper is at 80 ° C with a 2% aqueous solution

referred to in the Example 3, the triazine compound, which contains 0.5 ° / ₀ sodium carbonate, treated. The excess solution is squeezed off and dried at 120 ⁰ C. The dried paper is then post-treated with hot water and dried again at 80 ⁰ C. The paper is hydrophobic and has a soft feel

Example 5

A cellophane film is placed in a hot solution of 20 g / l 2-octadecylamino - 4 /? - sulfoethylamino - 6-chloro - 1,3,5-triazine and 5 g / l soda (calc.), Removed after about seconds ^{and dried at 130 °} C. for a few minutes. The film, which is briefly washed with warm water, has hydrophobic properties after drying.

A cellophane film treated in the same way with 20 g / l with 2,4-dichloro-6- (p-sulfophenylamino) -1,3,5-triazine sodium salt and g / l soda (calc.) Is treated after the treatment and subsequent Drying at 120 ⁰ C insoluble in alkali.
