Description
Technical field
The present invention relates to a kind of bleaching process, particularly relate to a kind of bleaching process of bamboo silk.
Background technology
Bamboo curtain splint is the traditional bamboo craftwork product of China, can review history of more than one thousand years, and it can be used as the carrier of drawing calligraphy creation, is mainly used in door and window decoration, partitions, screen etc., to build a kind of atmosphere of allusion grace.Liangping bamboo curtain splint as non-material cultural heritage adopts the braiding of thin bamboo silk to form, owing to containing active components of plants in bamboo wood, as vegetable protein, carbohydrate and starch etc., very easily by the mouldy blackening of bacterial action, especially serious in the season of humidity.Therefore, bamboo curtain splint raw material bamboo silk through bleaching, both need play mildew-proof function, and bamboo curtain splint background color can be made again evenly attractive in appearance, and is convenient to draw.
Traditional bleaching process is comparatively simple and easy, and generally only adopt simple sulfur fumigation or hydrogen peroxide solution to soak, existing bleaching and treating process has the following disadvantages: 1) after bleaching, the whiteness of bamboo silk is not enough, and white color and luster is undesirable; 2) bamboo silk uneven color after bleaching; 3) bamboo filament fibre damage is more, causes larger material loss, and cost increases.
For above-mentioned deficiency, a kind of bleaching process that can overcome above-mentioned deficiency need be explored, to promote the quality of bamboo curtain splint product.
Summary of the invention
In view of this, the invention provides a kind of bamboo silk bleaching process, the process employs unique bleaching liquid, and set rational processing step and parameter, to solve the technical problem that existing bamboo silk bleaching process bleaching effect is undesirable, bleach uneven color.
The present invention is solved the problems of the technologies described above by following technological means:
Bamboo silk bleaching process of the present invention, comprises the steps:
A) bleaching liquid is prepared: the hydrogen peroxide 13 ~ 15, the sodium tetraborate 0.2-0.3 Homogeneous phase mixing that by water 45 ~ 55, concentration are 25%-30% by weight, obtained bleaching liquid;
B) bamboo silk pretreatment: by weight portion be 45 ~ 55 bamboo silk be soaked in water and take out after 50 ~ 70min, airing 25 ~ 35min under normal temperature laboratory environment;
C) bleach: by step b) bamboo silk after airing be soaked in step a) obtained by bleaching liquid in, keep 60 ~ 90min behind heating bleaching liquid to 80 ~ 90 DEG C;
D) clean airing: take out bamboo silk and clean up with water, dry and obtain bleaching bamboo silk finished product.
Further, carry out described step c) before, the bleaching liquid that step is a) obtained is heated to 30 ~ 40 DEG C.
Further, described step b) in, soak after bamboo silk being bundled into the bamboo wire bundle of 90 ~ 110 grams, the elasticity of tying up can enter into bamboo wire bundle inside with water or bleaching liquid and be dipped into every root bamboo silk completely for standard.
Further, described step c) in heating time, under bamboo silk and bleaching liquid are placed in closed environment.
Further, described steps d) in, the mode of 2-3 time of making to be soaked in water cleans bamboo silk, and each soak time is not less than 1min.
Beneficial effect of the present invention is: bamboo silk bleaching process of the present invention, comprise step preparation bleaching liquid, the pretreatment of bamboo silk, bleaching and cleaning airing, this bleaching liquid parts by weight is that the hydrogen peroxide 13 ~ 15 of 25%-30% and sodium tetraborate 0.2-0.3 Homogeneous phase mixing are made by water 45 ~ 55, concentration, by controlling the conditions such as the ratio of bamboo silk and bleaching liquid and bleaching temperature time, bleaching liquid is made to have given play to best bleaching effect, the bamboo silk whiteness of gained is desirable, color is even, obtained bamboo curtain splint is more attractive in appearance, and be convenient to draw, quality there is an obvious lifting.By preheating bleaching liquid, the airtight modes such as bleaching of heating, can further improve bleaching effect, in addition, adopt the mode of tying up to bleach, the loss of bamboo silk can be greatly reduced, effectively control cost.
