Description

A kind of bamboo silk bleaching process

Technical field

The present invention relates to a kind of bleaching process, more particularly to a kind of bleaching process of bamboo silk.

Background technology

Bamboo curtain splint is the traditional bamboo craftwork product in China, can trace history of more than one thousand years, and it can be as the load of drawing calligraphy creation Body, it is mainly used in door and window decoration, cut-off, screen etc., to build a kind of classic graceful atmosphere.As non-material cultural heritage Liangping bamboo curtain splint using thin bamboo silk braiding form, due to containing active components of plants in bamboo wood, such as vegetable protein, carbohydrate With starch etc., it is especially serious in the season of humidity easily by the mouldy blackening of bacterial action.Therefore, bamboo curtain splint raw material bamboo silk needs By bleaching, mildew-proof function is both played, and can makes bamboo curtain splint background color uniformly attractive in appearance, and is easy to draw.

Traditional bleaching process is more simple, is normally only soaked using simple sulfur fumigation or hydrogen peroxide solution, Existing bleaching and treating process has the following disadvantages：1) the whiteness deficiency of bamboo silk, white color and luster are undesirable after bleaching；2) bleach Bamboo silk irregular colour is even afterwards；3) bamboo filament fibre damage is more, causes larger material loss, cost increase.

For above-mentioned deficiency, need to explore it is a kind of can overcome above-mentioned insufficient bleaching process, to lift the product of bamboo curtain splint product Matter.

The content of the invention

For overcome the deficiencies in the prior art, the present invention provides a kind of bleaching process of bamboo silk.

Present invention employs following technical scheme：A kind of bamboo silk bleaching process, comprises the following steps：

A) bleaching liquid is prepared：By weight by water 45~55, acetone 10~20, NaHCO3 5~10, potassium hydrogen persulfate Solution 2~5, concentration are the uniformly mixing of 25%-30% hydrogen peroxide 13~15, sodium tetraborate 0.2~0.3, and bleaching liquid is made；

B) bamboo silk pre-processes：The bamboo silk that parts by weight are 45~55 is soaked in water after 50~70min and taken out, indoors 25~35min is dried under normal temperature environment；

C) bleach：Bamboo silk after step b) is dried is soaked in the bleaching liquid obtained by step a), and heating bleaching liquid is extremely 60~90min is kept after 80~90 DEG C；

D) cleaning dries：Take out bamboo silk and cleaned up with water, dry and produce bleaching bamboo silk finished product.

Further, before carrying out the step c), bleaching liquid made from step a) is heated to 30~40 DEG C.

Further, in the step b), soaked after bamboo silk to be bundled into 90~110 grams of bamboo wire bundle, the elasticity tied up It can be entered inside bamboo wire bundle using water or bleaching liquid and be completely soaked every bamboo silk as standard.

Further, when being heated in the step c), bamboo silk and bleaching liquid are placed under closed environment.

Further, in the step d), the mode of 2-3 times of making to be soaked in water cleans bamboo silk, and each soak time is not low In 1min.

Beneficial effect：The bamboo silk bleaching process of the present invention, including step prepare bleaching liquid, the pretreatment of bamboo silk, bleaching and clear Wash drying, the condition such as bleaching formula of liquid, ratio and bleaching temperature time by controlling bamboo silk and bleaching liquid in the present invention, Bleaching liquid is set to have given play to optimal bleaching effect, bamboo silk whiteness ideal, the color of gained are uniform, and obtained bamboo curtain splint is more beautiful See, and be easy to draw, be obviously improved in quality.By preheating the modes such as bleaching liquid, closed heating bleaching, can further carry High bleaching effect, in addition, being bleached using the mode of tying up, the loss of bamboo silk, effective control cost can be greatly reduced.

Embodiment

With reference to embodiment, the present invention will be further described：

Embodiment 1：

A kind of bamboo silk bleaching process, comprises the following steps：

A) bleaching liquid is prepared：By weight by 45 parts of water, 10 parts of acetone, 5 parts of NaHCO3, hydrogen persulfate potassium solution 2 Part, 0.2 part of 13 parts of hydrogen peroxide, the sodium tetraborate uniformly mixing that concentration is 25%-30%, are made bleaching liquid；

B) bleaching liquid made from step a) is heated to 30~40 DEG C.

C) bamboo silk pre-processes：Soaked after bamboo silk to be bundled into 90~110 grams of bamboo wire bundle, the elasticity tied up is with water or drift It is standard that white liquor, which can enter inside bamboo wire bundle and be completely soaked every bamboo silk, and bamboo silk is soaked in water to be taken out after 50min, 25 min are dried under normal temperature environment indoors.

D) bleach：Bamboo silk after step b) is dried is soaked in the bleaching liquid obtained by step a), and heating bleaching liquid is extremely Keep 60min after 80 DEG C, during heating, bamboo silk and bleaching liquid are placed under closed environment.

E) cleaning dries：Take out bamboo silk simultaneously to be cleaned up with water, the mode of 2-3 times of making to be soaked in water cleans bamboo silk, every time Soak time is not less than 1min, dries and produces bleaching bamboo silk finished product.
