SU1516556A1 - Composition for dyeing fabrics of polyester fibre - Google Patents

Abstract

The invention relates to textile and finishing production and can be used in dyeing materials from polyester fibers with disperse dyes. The invention allows to simplify the composition and increase the content of the dye on the fiber due to the fact that the dyeing of polyester materials is carried out with a composition containing g / l: disperse dye 10-20, sodium hydroxide 1.0-2.0 and water - up to 1 l. 1 tab.

Description

The invention relates to dyeing and finishing production and can be used in dyeing materials from polyester fibers with disperse dyes.

The purpose of the invention is to test the content of the dye on the fiber and simplify the composition.

Example 1. A sample of fabric from polyester (PEF) fibers is plus an aqueous solution of the composition, g / l: scarlet dye Ж 10, sodium hydroxide 1, water to 1 l, wring out, dried for 2-3 minutes at 60 ° C, heat-set at 210 ° With 1.5 min, washed and dried. A uniform flat pattern is obtained. The dye content of the fiber is 7.4 g / kg.

Example 2. A sample of fabric from PEF fibers is plus an aqueous solution of the composition, g / l: scarlet dye W 15, sodium hydroxide 1, water to

1 l, squeeze, dry for 2-3 minutes, at 60 ° C, heat-set at 210 C and 1.5 minutes washed and dried. The dye content in the fiber is 10.5 g / kg.

Example 3. A sample of fabric from PEF fibers is plus an aqueous solution of the composition, g / l: scarlet dye W 20, sodium hydroxide 2, wring out, dried for 2-3 minutes at 60 ° C, heat-set at 210 ° C for 1 minute, washed. and dried. The dye content in the fiber is 13.0 g / kg.

PRI mme R 4. A sample of fabric made from PET fiber is added with an aqueous solution of g / l: scarlet dye J 5, sodium hydroxide 0.5; water to 1 l, wring out, dried for 2-3 minutes at, heat-set at 210 ° C for 1.5 minutes, washed and dried. The dye content in the fiber is 2.5 g / kg.

EXAMPLE 6 (comparative) A sample of PEF fiber fabric is carried out according to the mode of Example 1, but padding is carried out with the following composition, g / l: scarlet dye W 10, sodium hydroxide 0.5, water up to 1 l,

The content of the dye in the fiber is 6.1 g / l.

Example 7. The treatment of the PEF fiber fabric is carried out according to the mode of Example 1, but the padding is carried out with the following composition, g / l: scarlet dye W 10, sodium hydroxide 2, water to I l.

The content of the dye in the fiber

7.3g / kg

Example 8 The processing of fabric from PE fibers is carried out according to the mode of Example 1, but the melting is carried out with the following composition, g / l: scarlet dye G 10, sodium hydroxide 3, water to I l.

The content of the dye in the fiber

6.4g / c

Example 9 (comparative). PEF fiber fabric was processed by example, but padding was carried out with the following composition, g / l: spruce colored W 5, sodium hydroxide 1.0, water up to 1 liter ,,

The dye content in the fiber is 3.1 g / kg.

Example 10 (comparative) The treatment of the fabric made of PEF fiber is carried out according to the mode / example 1, but the padding is carried out with the following composition, g / l: geller 10, sodium hydroxide 0.5; water up to 1 l,

The content of the dye in the fiber 6.1 g / K

Example M (Comparative), The treatment of the fabric from PEF fiber is carried out according to the pattern of fy of Example 1, but the padding is carried out with the following composition, g / l: Scarlet dye G 25; sodium hydroxide 1.0; water up to 1 l.

The dye content in the fiber is 15.2 g / kg.

Example 12. A sample of fabric from PTF fibers plus an aqueous solution of the composition, g / l: scarlet dye W 10,

sodium hydroxide 1.5, wring out. Then the fabric is dried at within 2-3 minutes, thermofixed at 210 ° C

for 1.5 min, washed and dried. Get uniform saturated vykraski. The dye content in the fiber is 7.4 g / kg.

Example 13, Option 1 (by a known method). A sample of a PEF fiber fabric is plus a composition solution, g / l: dye 10, magnesium chloride 6 times, 25% aqueous solution is used as solvent.

air 2 min at 60 ° C; heat-set at 90 s; washed and dried.

Option 2 (according to the proposed method), A sample of PEF fiber fabric is plus an aqueous solution of the composition, g / l: dye 10, sodium hydroxide 1.5; squeeze out. Then the fabric is dried at 60 ° C for 2 minutes, heat-set

at 210 C for 90s; washed and dried.
