Technical field

The invention belongs to willow craftwork processing technique fields, and in particular to a kind of side for improving willow craftwork dye-uptake Method.

Background technique

Willow bark dull gray black, sulci of skin is wider, heartwood pale red, sapwood dark white, and annual ring is apparent.Wooden structures are thin Close, matter is soft, smooth after scraping, inflammable, and anti-corrosion ability is slightly worse.Sapwood width changes with growth conditions, and color is that light rice is brown Color.Its heartwood color is just on the contrary, for light red brown to taupe.Willow has the texture of fine homogeneous, although usually straight grain, Sometimes interlocking grain is had, or round line is presented.Civil, the use of willow has had history of more than one thousand years, therewith developing Raw willow craftwork is many kinds of, is liked by people.Willow craftwork raw material, color, in terms of shape At natural, simple, pure and fresh, terse artistic characteristics.Wherein existing thousand developing histories of craftwork processing skill, after number Succession, innovation for folk artisan, it has also become there is extensive representative folk art form, practical value, aesthetic value It obtains with social value and generally approves.Willow craftwork is the combination of simple tool and master-hand, be practicability with it is aesthetic In conjunction with, and by the innovation of skill, in structure and various different types of products are createed on object form, are met Masses' production and living needs, meanwhile, this folk art form also obtains significant progress.

People are always the power for finding and creating color to the pursuit of beauty, and traditional willow craftwork color is single, and The generation of dyestuff imparts the more vigor of craftwork.And the tinctorial property of willow does not protrude, so that the dyeing ability of dyestuff Allow of no optimist, there is dye species it is limited, dye-uptake is low, dyeing is uneven, fugitive color the problems such as.

Summary of the invention

The purpose of the present invention is being directed to existing problem, a kind of method for improving willow craftwork dye-uptake, energy are provided Illuminating colour is enough set to keep stablizing, uniform coloring achievees the purpose that improve dyestuff dye-uptake.

The present invention is achieved by the following technical solutions:

A method of willow craftwork dye-uptake is improved, the mordant being prepared is diluted using aqueous sodium carbonate 1000-1200 times, for pretreatment before the dyeing of willow craftwork；The mordant preparation method the following steps are included:

(1) it weighs 4.4-4.5 grams of cuprous oxide and 2.1-2.2 grams of lanthanum hydroxide is placed in a beaker, 40-50 milli is added into beaker Ethylene glycol is risen, after being dispersed with stirring 10-15 minutes, 15-20 milliliters of esters mixed solvents is measured, continues to be stirred 30-40 minutes, It obtains mixed slurry to be transferred in ultrasonic disperse machine, carry out ultrasonic disperse 15-20 minutes；

(2) 1.3-1.4 grams of antimony oxide is weighed, is slowly added into 30-35 milliliters of hydrochloric acid solution, dissolution stirring while adding obtains To uniform solution, it is added in the ultrasonic disperse object that step (1) is prepared, is transferred to round-bottomed flask after being uniformly mixed In, 1.0-1.2 grams of hexadecyltrimethylammonium chloride is added into flask, stirs lower water-bath and is heated to 45-50 DEG C, react 1.0- 1.5 hours, after the reaction was completed, be filtered, obtain solid product be placed in 60-70 milliliters of ethylenediamine-alcohol mixed solvents surpass Sound disperses 20-30 minutes, is transferred in reaction kettle, compressive reaction 2-3 hours at 90-100 DEG C, natural cooling cooling, decompression, Product is obtained using acetone washing and is filtered, then rotary evaporation 50-60 minutes at 100-105 DEG C, is pulverized, most postposition 3-5 hours are dried in 110-120 DEG C of vacuum oven to obtain the final product.

It is further described as to above scheme, the aqueous sodium carbonate mass concentration is 7.5-8.0%.

It is further described as to above scheme, the pretreatment temperature is 35-40 DEG C, handles the time as 20-25 points Clock is added dye liquor and is dyed after pretreatment.

It is further described as to above scheme, the mordant particle size is between 0.6-1.0 microns.

It is further described as to above scheme, step (1) the esters mixed solvent is according to mass ratio are as follows: acetic acid second Ester accounts for 20-25%, butyl acetate accounts for 10-15%, butyl acetate accounts for 5-10%, remaining as dehydrated alcohol.

It is further described as to above scheme, step (2) the hydrochloric acid solution mass concentration is 30-32%.

It is further described as to above scheme, ethylenediamine and second in step (2) ethylenediamine-alcohol mixed solvent Alcohol mass ratio is 1:3.5-3.7.

It is further described as to above scheme, step (2) the compressive reaction pressure is 0.35-0.40MPa.

It is further described as to above scheme, the additive amount of the mordant when in use is dyestuff quality 0.012-0.014%。

The present invention has the advantage that compared with prior art in order to solve the tinctorial property of existing willow and not protrude, there is The problems such as dye species are limited, dye-uptake is low, dyeing is uneven, fugitive color, the present invention provides a kind of raising willow craftworks The mordant being prepared is diluted 1000-1200 times using aqueous sodium carbonate, is used for willow craftwork by the method for dye-uptake Pretreatment before dyeing, the mordant being prepared mentions the dyeability of willow fiber and is obviously improved effect, in dyes It is pre-processed before color, by ion complexation, improves the Van der Waals force and Hyarogen-bonding between dyestuff and cellulosic molecule, To willow cellulose fibre affinity with higher and diffusion adsorptivity, illuminating colour can be made to keep stablizing, uniform coloring, Achieve the purpose that improving dyestuff dye-uptake can reduce the electricity in dyeing course on willow fiber when disseminating willow craftwork The coulomb repulsion that lotus generates coloring matter ion has higher affinity to cellulose fibre, improve dyestuff and fiber it Between binding force, reduce the dosage of dyestuff, enhance coloring light fastness and wet fastness, the raising willow technique that the present invention uses The tinctorial property that the method for product dye-uptake solves willow does not protrude, and there is dye species to be limited, dye-uptake is low, dyes not Uniformly, the problems such as fugitive color, dosage is small, at low cost, easily accomplishes scale production, and overcomes the difficult common fault of existing willow colouring, New thinking and direction are provided to dye the exploitation of auxiliary material, the development and utilization of mordant dyeing agent material is improved, can be realized The development for promoting willow craftwork industry, greatly improves the preservation reserve value of willow craftwork, is a kind of extremely worth The technical solution of popularization and use.
