Abstract
The invention relates to a method for preparing yellow silk, belonging to the spinning technical field of the textile engineering. The method comprises the following steps of: the first step, selecting Indian yellow as feeding pigment; the second step, preparing Indian yellow aqueous solution with the percentage concentration by weight of between 0.1 and 10 percent; the third step, adding antibiotic into the Indian yellow aqueous solution to prepare feeding pigment solution; the fourth step, evenly adding the feeding pigment solution into feeding fodder, and starting the feeding from the second day or the third day in fifth instar stage of silkworms until a day before mounting; and the fifth step, producing required yellow silk via cocoon drying and cocoon cooking after silkworms mounting and spinning cocoons. Color silk prepared by adopting the method has even color, glossiness and perfect color fastness.
Description
Technical field
The present invention relates to a kind ofly make silkworm secrete coloured silk-fibroin making the method for colored silk filament, particularly a kind of method for preparing yellow silk belongs to the throwing technical field of Textile Engineering.
Background technology
Understand according to the applicant, the method for existing production colored silk has following several usually:
1) utilizes natural colored silk insect resources seed selection chromatic cocoon kind.This method seed selection cycle is long, and the pigment of gained chromatic cocoon is skewness one in the silk material, and mainly concentrates in the silk gum, at filature, can take off in the processes such as refining, so production performance is poor, economic characters are difficult to practicability.
2) utilize bionic transgenosis means to produce the silkworm colourful silk, this technology is loaded down with trivial details, consuming time, consumption thing, poor practicability.
3) colouring method, on dyestuff is adhered real silk fully after, from dye liquor, take out real silk, the washing, drying, thereby make coloured real silk.The look silk uniformity and the COLOR FASTNESS of this method are all not ideal enough.
4) valve from the growth silkworm larva in the 4th five length of times of rest period to the is coated with dye liquor, apply some times, so that this dyestuff is absorbed by the sericterium in this silkworm body.This children silkworm can secrete silk from its orifice of spinneret subsequently, obtains coloured silk cocoon thus; Or silkworm larva is dipped in the dye liquor, this dyestuff is absorbed in the sericterium of this silkworm larva into by its valve, then, make this children silkworm secrete colored silk filament by orifice of spinneret.This method is not only loaded down with trivial details, and poor operability, can't walk out the laboratory and obtain promoting.
Summary of the invention
The objective of the invention is to: propose a kind of cost economy and be easy to grasp the method for preparing yellow silk of enforcement, thereby it is applied conscientiously, the yellow silk of excellent quality is provided for textile industry.
In order to reach above purpose, the method that the present invention prepares yellow silk may further comprise the steps:
The first step, select for use Indian yellow (for example CAS:No.518-47-8) for freshening the food pigment;
Second goes on foot, prepares the Indian yellow aqueous solution of weight percent concentration at 0.1%-10%;
The 3rd step, add antibiotic, be made into and freshen the food pigment solution at the Indian yellow aqueous solution; The antibiotic addition is advisable with its weight concentration 400-600ppm;
The 4th step, evenly add in feed for nursing and freshen the food pigment solution, began to the 3rd day to feed second day five age from silkworm, end the previous day until being placed on small straw bundles to spin cocoons;
The 5th the step, treat silkworm be placed on small straw bundles to spin cocoons cocoon after, through cocoon drying, cocoon cooking, filature, produce required yellow silk.
If add the food pigment solution add percentage by weight be 0.05-0.15% amino acid as auxiliary agent, can promote of the absorption of young silkworm to pigment.If continue in adding the food pigment solution, to add percentage by weight and be 0.1%-1% aluminium salt as auxiliary agent, will help to improve the COLOR FASTNESS of following look silk.
According to the method described above, when raising silkworm with mulberry leaf that added pigment solution or feed, intestines wall and the silk glands cell tissue of the young silkworm of the permeable mistake of this pigment solution, in it changes in quality for the process of silkworm chrysalis, the children silkworm secretes the silk-fibroin that to contain pigment, thereby makes the commercial variety that the does not possess pigment heredity controlling gene colored silk that can spue.Spin this colored cocoon, can obtain yellow and have glossiness silk.In the nursing process, owing to added antibiotic in the pigment solution, therefore avoided young silkworm to add the ill death of food pigment because of nibbling, its vitality and tradition are raised no significant difference.Even add after the food pigment, the same kind that the related economic proterties of part silk cocoon is not added pigment has the trend of increase.For example, the larva vital rates of trial zone, the rate of cocooing, cocoon layer rate etc. contrast the raising that certain amplitude is all arranged.And, because pigment just was mixed in wherein before silk-fibroin secretion and sclerosis among the present invention, this protein substance gets up at young silkworm body accumulation, so silk-fibroin is directly dyeed by this pigment solution, can make secreted silk even dyeing like this, have very good COLOR FASTNESS.
The specific embodiment
Embodiment one
Embodiment 1:
The choice structure type is the Indian yellow 73 (CAS:No.518-47-8) of the quinoid of xanthene.Its molecular weight is 376.27, is water-soluble dye.The Indian yellow aqueous solution of preparation (weight) concentration range between 0.1%-10%.The auxiliary agent that adds at the Indian yellow aqueous solution has: weight concentration is the antibiotic (orfloxacin or norfloxacin) of 500ppm; Weight concentration is the aluminium salt of 0.1%-1%; And weight concentration is 0.1% amino acid, is mixed with and freshens the food pigment solution.This is added the food pigment solution be sprayed on the mulberry leaf, principle is even and not drip, in feeding silkworm in the 3rd day five ages.
In freshening the process of food, note dissecting young silkworm, observe the painted situation of sericterium every 24 hours.Add food and dissect young silkworm after three days, find sericterium from spinneret to the posterior division of silkgland all coloring.
Raise silkworm to being placed on small straw bundles to spin cocoons the previous day with having added the mulberry leaf that add the food pigment solution.Note the humiture that control is placed on small straw bundles to spin cocoons according to a conventional method.Temperature is controlled at about 24 ℃, and humidity is about 65%.Be placed on small straw bundles to spin cocoons the back adopted in the 7th day the yellow color cocoon.
Press conventional cocoon drying, the cocoon cooking process of table 1, table 2 and handle chromatic cocoon, carry out single cocoon reeling.Filature speed 120r/min, filature is till the pelettes always.Colored silk is placed in the electric drying oven with forced convection 100 ℃ of freeze-day with constant temperature 3 hours, is placed in 25 ± 2 ℃, relative humidity 65 ± 5% balance after the taking-up 48 hours, can obtain lovely luster, the strong yellow silk of light rhythm sense.
