Embodiment 1

[0052] The water boiling of embodiment 1 timber handles waste liquid

[0053] (1) Put the eucalyptus board to be boiled into the wood cooking equipment wood cooking tank, and put distilled water into the wood cooking tank and submerge the eucalyptus board; (2) heat up until the water temperature reaches and maintains 80°C ( Usually can also be 60-100 ℃), carry out the poaching treatment of wood; (3) after 4.5h of poaching treatment, wood is taken out, and remaining solution is eucalyptus poaching treatment waste liquid, wherein, wood poaching time It is 1.5h / cm (usually the boiling time of wood can also be 1-2h / cm).

[0054] The boiling treatment waste liquid of embodiment 1A timber

[0055] Except also adding alkaline reagent sodium hydroxide when putting into water in the wood poaching container in step (1), all the other are identical with embodiment 1. Wherein, the mass ratio of sodium hydroxide to distilled water is 3:100 (usually also can be 0.5-8:100).

[0056] In th...

Embodiment 2

[0057] The steaming treatment waste liquid of embodiment 2 wood

[0058] (1) Palletize the wood and put it into the wood steaming kiln (steaming treatment device); (2) Close the wood steaming kiln, turn on the heater, and pass superheated steam into the steaming kiln; (3) Heating the wood inside the steaming treatment device (steaming kiln), the temperature in the temperature control device reaches and maintains at 90°C, and performs steaming treatment of the wood; (4) Performs steaming treatment under the condition of maintaining the temperature at 90°C After 6 hours, the wood was taken out, and the condensate left at the bottom of the steaming treatment was the eucalyptus wood steaming treatment waste liquid.

[0059] The purpose of boiling treatment and steaming treatment is to make the extract inside the wood discharge the wood conduit under the action of hot water / steam, so that the wood extract flows out.

[0060] In order to increase the content of extracts in wood hyd...

Embodiment 3

[0066] 1. Wood hydrothermal treatment waste liquid pretreatment

[0067] The eucalyptus steaming treatment waste liquid prepared in Example 2 was collected, filtered, and concentrated, the water was evaporated, and the eucalyptus hydrothermal treatment waste liquid was concentrated until the extract content reached 5%, and the hydrothermal treatment concentrated waste liquid was obtained. Standby, wherein, the extract content in the hydrothermally treated concentrated waste liquid is determined according to the method of the national standard GB / T 2677-4-1993 (Determination of the water extract content of papermaking raw materials).

[0068] In addition to the steamed waste liquid prepared in Example 2, the mixed solution of boiled waste liquid and steamed waste liquid is also applicable.

[0069] 2. Dyeing treatment

[0070] Put 10g of silk into 100ml of concentrated steaming waste liquid, wherein the ratio of the mass of fabric (silk) to the volume of waste liquid is 1:10 (...

Abstract

The invention discloses a method for dyeing a fabric or / and fabric fiber by using a wood hydrothermal treatment waste liquid and belongs to the field of wood processing. The method for dyeing the fabric or / and fabric fiber by using the wood hydrothermal treatment waste liquid comprises the following steps: collecting a waste liquid generated from wood hydrothermal treatment; putting the fabric or / and fabric fiber into the waste liquid, heating to 50-100 DEG C, and keeping the temperature for 0.5-2 hours. By adopting the method, the waste liquid generated in wood hydrothermal treatment is sufficiently utilized, and the process is simple and convenient; meanwhile, coloring groups in the wood hydrothermal treatment waste liquid are reacted with amino on the fabric fiber, so that a solid and long-lasting dyeing effect on the fabric or / and fabric fiber can be achieved.

Description

technical field [0001] The invention relates to the field of wood hydrothermal treatment, in particular to a method for dyeing fabric or / and fabric fibers by utilizing wood hydrothermal treatment waste liquid. Background technique [0002] At present, my country's plantation area has reached 62 million hectares, accounting for 38% of the global plantation area, ranking first in the world. Among them, fast-growing eucalyptus is the most important fast-growing wood, and its reserves are huge. However, due to the high initial moisture content of fast-growing eucalyptus , and a series of problems such as large deviations and easy to produce drying defects have seriously restricted the application range of eucalyptus. Although the drying problem of eucalyptus wood is solved in this process, because the extract inside eucalyptus wood is removed under humid and hot conditions during the steaming or boiling treatment process, wood hydrothermal treatment waste liquid is generated. At ...
