Description
The present invention relates to a kind of manufacturing technology of silkworm bulk silk.
Before the present invention makes, technique known " the reel silk from cocoons system of dividing fibril " joint in " research that divides the fibril fabric about exploitation " literary composition that is entitled as publishing on Japan's " will is dyed in the capital " magazine in 1986, its method is: when cocoon cooking, the high lukewarm water that the cocoon cage that dried cocoon is housed is put into about 95 ℃ floods, move into the interior dipping of pervasion swelling agent solution of the certain density higher alcohol sulfuric acid of 70 ℃ be furnished with ether system then, after taking out the interior insulation of the container soup that drops into about 40 ℃, finish cocoon cooking; When filature, do not do crosisure, the silk bundle that will have the purpose fiber number directly is wound up on the little , turns off little baking fiber tube; Turn off big baking fiber tube during rereeling; During post processing, will put into 50 ℃ general from the silk sheet that big takes off and flood,, on Water Extraction Machinery, dewater at last, and stretch tight and thread dry through the warm water washing with softener solution.In the manufacture process of this minute fibril, because during cocoon cooking, through high temperature dipping more than 95 ℃, therefore, the natural rolled state evanescence of silk, the fibroin molecule easily produces crystallization, the flexibility of strand is relatively poor, because of the thermal type that adopts permeates half heavy cocoons-boiling method, the suction of cocoon chamber is abundant inadequately again, has influenced the quality and the silk production rate of silk.
The purpose of this invention is to provide a kind of flexibility bulky yarn manufacturing technique and equipment that improves bulky yarn quality and silk production rate.
Realize the manufacture method of the silkworm bulk silk of the object of the invention, form that its cocoon cooking operation is a: the cocoon cage that will fill silk cocoon is put into vacuum tank, then to evacuating atmosphere in vacuum vessel by cocoon cooking, filature, rereeling and post processing four procedures; B: vacuum tank sucks the cocoon cooking soup that contains the raw silk swelling agent in storage soup container, Tang Wen is 38～40 ℃; C: then above-mentioned cocoon cage is moved in the cool-bag, its silk cocoon is incubated in Tang Wen is 78～80 ℃ of insulation soup that contain the raw silk swelling agent, takes out after about 15 minutes, finishes cocoon cooking.In the filature operation, reeling tension is controlled in 0.2～0.3CN/D scope.
The equipment of bulky yarn manufacturing technique of the present invention comprises cocoon cooking system, reeling machine, rereeling car; Wherein cocoon cooking system is a vacuum cocoon cooking system, in comprising, it puts vacuum tank (3), storage soup container (2), the cool-bag (4) of a cocoon cage, vavuum pump (1) is connected with vacuum tank (3) with pipeline by valve, and the inlet of vacuum tank (3) communicates with storage soup container (2) by valve and pipeline; The rereeling car, its big is the big structure of circle, its angle and coiling strand contact position are circular arc.In these equipment, the cocoon cooking system is a cover special equipment, and filature equipment is common multiends reeling machine, and the circular-arc profile at big structure of the circle of rereeling car and angle can reduce the tension fluctuation of strand on big angle.
Bulky yarn by mulberry silk manufacturing technology of the present invention is produced owing to adopted the cryogenic vacuum cocoon cooking process, has kept the natural curl characteristics of silk, the flexibility and the bulkiness of strand are improved, simultaneously, because cocoon chamber suction foot, silk cocoon boils evenly, has improved silk production rate; Also owing to adopted the big rereeling of circle, angle rounding off has overcome the defective of angle set, has improved the quality of bulky yarn.Be processed into knit product with this bulky yarn, have bulk, soft, plentiful feel and good wearability.Bulky yarn manufacturing technology of the present invention also has characteristics such as technology compactness, equipment be simple.
Technical scheme of the present invention can also be made following further instruction by accompanying drawing:
Fig. 1 is the cocoon cooking process flow chart of the embodiment of the invention, and this figure also is the cocoon cooking system equipment structure diagram of this embodiment simultaneously.
Fig. 2 is the big structure diagram of the circle of this embodiment rereeling car.
Fig. 3 is the angle sections figure of the big of this embodiment circle.
Mulberry silk manufacturing technology of the present invention mainly is made up of technologies such as cocoon cooking, filature, rereeling and post processings, and its capital equipment comprises cocoon cooking system, reeling machine, rereeling car.
What the cocoon cooking system adopted is the cryogenic vacuum cocoon cooking process, and its capital equipment is referring to accompanying drawing 1, and it is by vacuum tank 3, storage soup container 2, cool-bag 4, storage cocoon container 5, vavuum pump 1 is formed, vacuum tank is the cylinder bodily form, in a cocoon cage is arranged, on a gland is arranged, liquid level gauge, Pressure gauge etc. also are installed on the container, top one exhaust outlet is connected by pipeline, valve and vavuum pump, and bottom one inlet is connected feeding storage soup container bottom by pipeline with valve.Storage soup container and cool-bag structural similarity, bottom plate has steam pipe, connects with outside steam pipeline, valve, is used for heating container Nei Tangwen; After tapping into water valve respectively, connects the water inlet of storage soup container, cool-bag, storage cocoon container with water inlet pipe.
Contrast accompanying drawing 1 when cocoon cooking, drops into the raw silk leavening agent in storage soup container 2 and the cool-bag 4 by 60%～70% concentration preparation back earlier, opens cap relief valve, and two containers are heated to 40 ℃ and 80 ℃ respectively.This method that adds medicine in cocoon cooking soup because swelling agent infiltrates silk gum inside, not only promotes the silk gum swelling, and increase the intermittence between silk, and has increased the plasticity of raw silk, thereby has improved the bulkiness and the flexibility of silk.A certain amount of raw material cocoon is put into the cocoon cage, again the cocoon cage is put into vacuum tank 3, fasten container cover, open air bleeding valve, open vavuum pump 1,, make container vacuum reach 0.095～0.10MPa evacuating atmosphere in vacuum vessel.Drive the liquid valve into and suck solution in the storage soup container, open intake valve then, the cocoon chamber is fully absorbed water.The cocoon cage takes out from vacuum tank, puts into cool-bag, and cocoon cooking soup temperature remains on about 80 ℃.Because in the silk gum temperature---on the solubility curve, 80 ℃ is the rapid change point of silk gum, and therefore, the cocoon cooking temperature remains on below 80 ℃, can suppress the dissolving of cocoon layer silk gum, keeps the natural curl characteristics of silk.Silk cocoon finishes cocoon cooking after insulation in 12～15 minutes in cocoon cooking soup, take out and put into storage cocoon container 5, treats filature usefulness.
Filature carries out on common multi end reeling machine, and without the crosisure device, the silk bundle directly batches on the little after the collection thread, turn off little baking fiber tube, and the control reeling tension is in 0.2～0.3CN/D scope.
Fall behind the silk, little silk sheet be impregnated in the rereeling compounding agent solution, solution concentration is 1.5%, 40 ℃ of temperature, dip time 15～20 minutes.Behind the silk sheet dipping, on rereeling machine, do not drive the baking fiber tube and do rereeling with the big of circle, contrast accompanying drawing 2,3, the angle profile of the big device of circle is circular-arc, adopt light and hard wood material to make, and each limit chamfering sanding, make silk bar and corner connection synapsis rounding off, prevented that the angle is located to produce the set of angle because of the tension fluctuation of strand in the rereeling, improved the bulkiness and the raw silk quality of silk.
Rereeling is promptly stayed the thread lacing after finishing, and then silk is taken off, and dipping is 20 minutes in the rereeling auxiliary agent.In order to prevent that strand from producing plastic deformation because of the drying contraction on little or big and the fibroin molecular crystallineization descends pliability, filature, the baking fiber tube is not all driven in rereeling, but do not drive the baking fiber tube, silk sheet regain height, easily cause the adhesion between hard angle and strand, therefore, to little , big silk sheet with rereeling auxiliary agent dipping, contains certain lubricant component and softener respectively in the rereeling auxiliary agent, the silk sheet is by soaking, part softener infiltrates the silk gum intramolecule, makes the silk gum molecular structure loose, increases silk gum molecule plasticity, reach softening purpose, lubricant component then forms one deck oil film on the strand surface, increases flatness, prevents to produce between strand adhesion.A silk sheet after treatment dewaters with Water Extraction Machinery, through the silk that stretches tight, is hung on and indoorly dries naturally, and the silkworm bulk silk that obtains can be without soft treatment, is directly used in knittingly, and its product has characteristics such as bulk, soft, plentiful.
