Abstract
The invention discloses a kind of silk fabric method for bleaching, belong to silk fabric production field.The method following steps: preparation bleaching liquor, the key component of bleaching liquor is 30%H2O2And stabilizer, ultrasonic agitation mix homogeneously, by adding alkali regulation solution ph to 10.5 11；Prepare silk fabric, and fasten with polyester thread；Silk fabric is soaked bleaching liquor, two leaching two bundles, it is warming up to 95 120 DEG C, decatize a period of time, it is cooled to 70 DEG C with the speed of 2 DEG C/min, bleaching liquor is discharged, clean with hot water, discharging cleanout fluid after cooling, the acetic acid of the cleanout fluid after discharge neutralizes, and then uses cold water flush.The method can effectively keep whiteness and its intensity of silk fabric, and the natural pigment of silkworm silk is not resulted in destruction yet, is a kind of eco-friendly method for bleaching.
Description
Technical field:
The present invention relates to silk fabric production field, relate in particular to the drift of a kind of silk fabric
Whitening method.
Background technology:
Silkworm silk be matured silkworm when cocooing secreted silk liquid concretionary continuously " long fibre ", also become
" natural silk ", is a kind of natural fiber.Silkworm silk is the most soft the thinnest natural in nature
Fiber, can easily restore to the original state after cancelling external force, the inner tube of a tyre not molding, the most stuffy, not purse up,
The softest, can forever exempt to turn over use.
The main body of silkworm silk is fibroin, additionally, it also includes natural impurity (sericin, adipocere, color
Element, inorganic matter and carbohydrate) and artificial impurity (coloring agent, greasy dirt).Silkworm silk
Pre-treatment include refine and bleaching.Refine i.e. the degumming tech of silkworm silk, in general silkworm silk
Impurity be all attached to above sericin, therefore, it is miscellaneous that scouring processes can remove other in silkworm silk
Matter.
Although eliminating the natural impuritys such as sericin and artificial impurity after silk fabric is refined, but its
Whiteness still reaches to less than requiring, therefore, in the actual production process of silk fabric, refine and
Bleaching is carried out the most simultaneously.Bleaching is possible not only to remove the natural pigment in silk fabric, gives
The whiteness of its necessity, it is also possible to remove the residual impurity in silk fabric further, improve silkworm silk
The wettability of fabric.
The at present conventional oxidizing bleach of bleach (sodium hydrosulfite, sodium sulfite etc.) and
Reproducibility bleach (sodium hypochlorite, hydrogen peroxide, sodium chlorite etc.).Oxidisability is bleached
Agent, the fabric whiteness instability after it exists bleaching i.e. aoxidizes the shortcomings such as secondary color, and reproducibility is floated
White agent also exists the problems such as environmental pollution.Due to silk fabric main body fibroin for reducing agent relatively
Stable, but the ability for antioxidant is poor.The bleach of chloride element cannot be used for egg
The white matter fabric i.e. bleaching of silk fabric, because it can make fibroin generate chloramines and yellowing, and
The strength also resulting in silk declines.
Summary of the invention:
It is an object of the invention to provide the method for bleaching of a kind of silk fabric, this method for bleaching, right
Human body and environmental nonpollution, and make the silk fabric whiteness after bleaching stable.
The purpose of the present invention is achieved through the following technical solutions:
(1) preparation bleaching liquor, the key component of bleaching liquor is 30%H2O2And stabilizer, ultrasonic stir
Mix mix homogeneously, by interpolation alkali regulation solution ph to 10.5-11；
(2) prepare silk fabric, and fasten with polyester thread；
(3) silk fabric is soaked bleaching liquor, two leaching two bundles, it is warming up to 95-120 DEG C, decatize
A period of time, it is cooled to 70 DEG C with the speed of 2 DEG C/min, bleaching liquor is discharged, clean with hot water,
Discharging cleanout fluid after cooling, the acetic acid of the cleanout fluid after discharge neutralizes, and then uses cold water flush.
Preferred as above-mentioned technology, bleaching liquor composition quality is frequently: 30%H2O2: stabilizer
For 1:2-1:5.
Preferred as above-mentioned technology, steam temperature is 100-120 DEG C, and steaming time is
30-90min。
Preferred as above-mentioned technology, selected stabilizer is sodium silicate.
Preferred as above-mentioned technology, in step 1, the alkali of selected regulation bleaching liquor pH value is hydrogen-oxygen
Change potassium.
The beneficial effects of the present invention is: the main body fibroin of silk fabric is more steady for reducing agent
Fixed, but the ability for antioxidant is poor.The bleach of chloride element cannot be used for albumen
The matter fabric i.e. bleaching of silk fabric, because it can make fibroin generate chloramines and yellowing, but also
The strength that can cause silk declines.And H2O2It is a kind of comparatively gentle bleach, and bleaches
Product whiteness is stable, during bleaching, it is generally recognized that HO2 -It is the main component of bleaching liquor, destroys
The conjugated double bond of pigment, reaches the purpose of colour killing bleaching.Additionally, H2O2In bleaching process
In addition to natural colour is have destruction, also can make cellulose oxidation and impaired, therefore simultaneously
The decomposition rate of hydrogen peroxide to be efficiently controlled in bleaching process, to add certain in bleaching liquor
The sodium silicate of amount is used as stabilizer.This method for bleaching is pollution-free to environment and human body.
