Description
Technical field
The invention belongs to textile dyeing and finishing field, particularly the fiber bleached technique of a kind of human hair.
Background technology
Along with growth in the living standard, wig has become the rare crowd of hair and the necessary article of the personage that likes to be beautiful, and these people need the wig of more color to prick up oneself.In addition, to like to be beautiful fashion as one, wear wig liking deeply by many stars and high consumption crowd, and people are more and more frequent for the renewal of wig, this wig industrial expansion just promoted.Although the wig color of chemical fibre class is beautiful and cheap, if wear-time is long, the senses of discomfort such as stuffy, dry can be brought to people, even may cause disease of skin.And human hair belongs to natural fabric, sucting wet air permeability and anti-flammability etc. are better than chemical fibre class wig far away, are therefore still the first-selection of people with the wig that human hair is made.Chinese Hair color is based on black, even yellow etc. variegated with bletilla, for meeting the different requirements of different crowd to wig look, must carry out bleaching and dyeing process to human hair.
The basis of hair is keratin protein, keratin protein is made up of amino acid, their improve nutrition needed for natural on-off cycles of hair growth and composition, each seed amino acid fiber is wound around mutually crosslinked by mechanism that is spiral, spring, form the intensity of keratoprotein and pliable and tough, thus impart the exclusive strong and unyielding performance of hair.So bleaching in human hair fiber process the destruction also will avoiding the complete crosslinking method of each seed amino acid fiber while that to propose in human hair fiber melanic, the human hair fibre technology technology that damage is little, yield is high so just can be obtained.
Liu Baojiang etc. disclose a kind of method for bleaching of human hair fiber low-carbon (LC) in Chinese patent application 201010598676.7, by adding protease, photooxidation bleaching and washing, obtain the fiber bleached technique of the human hair with certain bleaching effect.In addition, Liu Baojiang etc. disclose a kind of method for bleaching of human hair fibers at low temperature with low damage in Chinese patent application 201010598379.2, by adding agent pretreatment fluid of scaling in human hair fiber, and then human hair fiber is put into pre-matchmaker's treatment fluid, last low-temperature activated bleaching, obtains the fiber bleached technique of the human hair with certain fibre whiteness.Above-mentioned report adopts diverse ways to carry out bleaching to human hair fiber, but does not do further investigated to the fiber bleached whiteness of human hair, contradiction between yield and intensity.Chemicals adds comparatively complicated simultaneously, and the current technology for enterprise need do larger amendment.
Sun Yunfei etc. are in " wool spinning science and technology " paper that the 42nd volume the 7th phase 21-24 page was delivered in 2014, adopt oxalic acid and ferrous ion first to form complex compound and catalytic pretreatment is carried out to human hair fiber, take hydrogen peroxide as drift agent, investigated oxalic acid and ferrous salt consumption, catalytic reaction temperature and time to the impact of bleaching people's degree of blushing and ultimate strength.But the research emphasis of this paper is the process optimization of catalytic pretreatment, in yield, whiteness and intensity, do not have further investigated.
In recent years, the market demand of human hair fiber increases, and price is more and more higher.And report from current correlative study, the fiber bleached whiteness of human hair, contradiction between yield and intensity still fail effectively to be overcome, the fiber bleached technique of human hair of high yield pulp1, high whiteness, low damage, the bleaching process being simultaneously applicable to existing enterprise's process modification is the dual needs improving the quality of products, meet the need of market.
Summary of the invention
Object of the present invention, be to provide a kind of human hair fiber bleached technique, this technique is the improvement of industrialization process, in the fed batch technique of oxidation processes section, effectively can reduce the oxidant concentration in bleach system, add when oxidant concentration is lower in good time, and realize the post-bleach of human hair fiber in reduction treatment section.Have that technique is simple, with low cost, efficiency is high, it is little to pollute, energy consumption is low, easy suitability for industrialized production, good to the bleaching effect of human hair fiber, damage little, there is good development prospect and economic worth.
