Description
Technical field
The present invention relates to textile technology field, thereby relate in particular to a kind of detection system and detection method that fast silk gum concentration in the silk gum silk degumming liquid is detected acquisition silk degumming rate.
Background technology
China is exactly the big country that a silk is produced since ancient times, and the Silk Road has made referrals to the whole world with China especially.Have document announcement China silk silk fabric production scale to rank first in the world, 2007 produce about 500,000 tons of silk cocoons (account for world production total amount 80%) per year; Raw silk is more than 70,000 tons (account for world production total amount 60%), and silk output accounts for about 45% of Gross World Product.Silk is that China can dominate one of only a few advantageous agricultural product of international market.
Silk is made up of two monofilament, and its main body is a fibroin, the outer silk gum that coats.Silk gum mainly is made up of misaligned amorphism silk gum globulin; Wherein serine, aspartic acid and glycocoll content are higher; Relative mass reaches 33.43%, 16.71% and 13.49% respectively, contains the structure that two peptide chains connect through disulfide bond in the molecule.The secondary structure of sericin is main with random coil, and contains part β structure picture, contains αLuo Xuanjiegou hardly.Most pigment, grease, wax and inorganic salts etc. are present in the silk gum.For the preparation fiber-spinnable, concerning silk, part or all of silk gum must to be removed.In silk processing, call the process of removing silk gum and grease concise; Be most basic one technology of Silk Industry, all following process all had decisive influence, for example; Aspect dyeing, coming unstuck not enough is prone to dyeing flower, dyes irregularly, and the excessive then feel of coming unstuck is too poor.
The kiering of degumming tech original adoption alkalescence is used for hand spinning more.18th century, used bacterial degumming method in the industry, claim again to ferment and come unstuck, be commonly called as corruption and practice; Chemical degumming law (being commonly called as chemistry practices) and enzyme preparation method for degumming have appearred again subsequently.The alkalescence kiering is the key link of chemical Degumming, and the kiering number of times is decided by material quality and technological requirement.The bases of using has sodium carbonate and sodium silicate etc., tussah cocoon available hydrogen sodium oxide molybdena.The auxiliary agent that adopts has bleeding agent and detergent etc.The principal element that influence is come unstuck has: pH value, temperature, bath raio and the time of practicing liquid.The advantage of chemical Degumming is that the speed of coming unstuck is fast, occupied ground is few, is suitable for serialization production.Equipment mainly contains practices bucket, cartridge type scouring machine, belt scouring machine, hydrodynamic cleaning machine and dryer etc.
In at present silk comes unstuck production run, utilize traditional technology can't obtain in the degumming degree of silk the science data of degumming degree in real time.
Existing technology to the measurement of silk degumming rate method commonly used is:
(1) gravimetric method is promptly measured reduction rate, and this method precision is high, but required time is long.It is before concise and after concise, 20 ℃ of room temperatures, under the condition of relative humidity 60%, with the water percentage maintenance equilibrium state of silk.Measure weight at that time.Can calculate degumming rate thus.If use the method to measure the degumming rate of silk, because the needs of balance were accomplished whole process nearly 24 hours.Therefore, the method can't be monitored the silk degumming degree in process of production in real time.
(2) also having a kind of method is colouring, i.e. the painted back of the subjective observation silk gum tinctorial yield different with fibroin, and colorant commonly used is carmine method.This method operation is simple relatively, need not carry out the sample balance, and whole test process can be accomplished in the relatively short time, but precision is not high, and measurement result can only supply qualitative analysis.
General physics general knowledge is told us: the conductance of the WS directly and dissolved solids concentration like the content of contained mineral acid, alkali, salt certain relation is arranged, and amount of solid concentration is high more, and conductance is big more.The conductance size of solution depends on the motion of molecule simultaneously, and the motion of temperature effect molecule can be compared in order to make measurement result, and probe temperature generally is decided to be 20 ℃ or 25 ℃.Conductance changes with temperature variation, 1 ℃ of the every rising of temperature, and conductance increases about 2%.
Through to China, the retrieval of the U.S. and European patent database, we can obtain: the patent that the treatment process of relevant silk is relevant has had many reports.It is a kind of with the immobilized electrochemical test method that on electrode surface, can directly detect the bioactivator in the sample as working electrode fast of sericin that one Chinese patent application 03129676.9 provides; 200910102355.0 reported the breeding method of dedicated silkworm hybrid that a kind of secreting natural, high-load, green sericin are provided; 95121406.3 introduced a kind of smart method of nutritious foodstuff silk of producing with silk; 85105350 and 85100524 have introduced process for chemical degumming of hemp respectively and a kind of natural fiber carries out degumming tech and method with two kinds of dissimilar protein yeasts.
As above how many publications all do not make referrals to through the mensuration of content of silk gum in the silk degumming liquid being predicted the amount of coming unstuck of silk, and then the silk process of coming unstuck is optimized control.And comprehensively the retrieval to numerous documents does not all have to find the relevant report that utilizes the conductance detection content of silk gum of silk degumming liquid, does not more utilize this characteristic to carry out the silk degumming rate and calculates.
