Abstract
The invention discloses a kind of production method of extra-fine mulberry silk twill.Be induce four molt silkworm three dormancyizatioies with medicine " ultra-fine element ", produce the ultrafine-titer silk cocoon that filament number is 1 DENIER; With the hot-air of temperature long period on the low side again dry method cocoon is baked dried cocoon; By the steam cocoon cooking method of temperature on the low side and inclined short time, dried cocoon is cooked into ripe cocoon; Determine cocoon 10, the ultra-fine raw silk of 9/11D specification made by reel silk from cocoons; With the ultra-fine raw silk of 6+8 root 9/11D specification, be woven into ultrafine mulberry silk fabric; With thickener PS-14 for medium, modulation acid red, Huang, blue dye coupler slurry, retouch the plate-making of original text by color separation, be imprinted on by mill base and practice on white fabric through coming unstuck, make the extra-fine mulberry silk twill product of various floral pattern.The twill silk that the present invention produces, gloss is unique, and crease-resistant, dyeability is good, and COLOR FASTNESS is high, and chromaticness is bright-coloured, and economic worth is large; Traditional Silk Industry can be promoted simultaneously, meet the multiple demand of domestic and international market.
Description
Technical field
The present invention relates to a kind of production method of twill silk, especially relate to a kind of production method of extra-fine mulberry silk twill.
Background technology
Silk fabric is thin only bright and clean, has that gloss is soft, quality is frivolous, soft and high resilience, strong, the magnificent noble quality of hygroscopicity, to characteristics such as body-cares, can be made into clothes, ornament, indoor article, handicraft etc.Mulberry silk twill silk is a kind of real silk fabric being organized as the similar drillipg of twill structure, and cloth cover has obvious oblique lines, feel, gloss, each elasticity better.Traditional silk twill silk is 2.8 ~ 3.0 DENIER (Denier by filament number, D) 20/22D, 27/29D, 28/30D, 34/36D equal-specification raw silk weaving that common silk cocoon reel silk from cocoons is made is produced, its wrinkle resistance and dyeability poor, this does not meet the multiple demand of society.
The fabric that fine denier raw silk is made into has the characteristics such as thin, wrinkle resistance strong, be rich in gloss, Color is good.Chinese scholars is devoted to study in this respect always, mainly take the fine denier silkworm breeding such as " dawn ", " silver ", " SG ", " 305 ", " 853 is white ", " 543B ", with the medicine such as SD-III, KK-42, KK-22, common four moultinism kind silkworm mutagenesis are become these 2 approach of trimolter, produce the fine denier raw silk of 13/15D, 15/17D specification.Although these two kinds of specification raw silk sizes of 13/15D, 15/17D are thinner than traditional raw silk size, the needs of specific use still can not be met by the twill silk product characteristics that it is produced.
Summary of the invention
The object of the present invention is to provide a kind of production method of extra-fine mulberry silk twill, induce four molt silkworm three dormancyizatioies with medicine " ultra-fine element ", manufacture order silk size is 1 DENIER (Denier, D) the ultra-fine silk cocoon of high-quality, the ultra-fine raw silk of high-quality making 9/11D specification with this silk cocoon reel silk from cocoons, extra-fine mulberry silk twill product is become with this raw silk weaving, this product is compared with common mulberry silk twill silk product, local flavor, dyeing, COLOR FASTNESS, refractive power, the performance such as crease-resistant significantly improve, economic worth is large, can meet the new demand of New Times people.
In order to achieve the above object, the technical solution used in the present invention is as follows:
1) at 25 ~ 28 DEG C, raise with proper mature (ripe) mulberry leaf the four moultinism kind silkworms to 4 producing upper practicality and play silkworm age, employing is sprayed at the continuous feeding method of 24 ~ 48 hours after on proper mature (ripe) mulberry leaf, to the medicine " ultra-fine element " playing silkworm 4 ages and freshen food 0.1 mg/ bar silkworm dosage, induce its three dormancyization, continuing to raise at 24 ~ 25 DEG C to ripe with not spraying medicine proper mature (ripe) mulberry leaf, cocooing and producing the high-quality ultrafine-titer silk cocoon that filament number is 1 D;
2) high-quality ultrafine-titer silk cocoon is dried 1.5 hours at 89 ~ 91 DEG C, then go out returning property of stove Long Dui 12 hours, then enter stove and dry 2 hours from the mode that 90 DEG C are at the uniform velocity reduced to 75 DEG C, bake dried cocoon;
3) by dried cocoon priority seeping at high temperature section temperature 94 ~ 96 DEG C, low temperature osmotic section temperature 54 ~ 56 DEG C, steaming stage temperature 94 ~ 96 DEG C, adjustment section temperature 80 ~ 90 DEG C, outlet protection section temperature 49 ~ 51 DEG C of difference cocoon cooking 2 minutes, 1 minute, 2 minutes, 1 minute, 1 minute, ripe cocoon is cooked into;
4) girth is become by ripe cocoon reel silk from cocoons on reeling machine to be the little silk sheet of 0.65 ~ 0.7 meter, its technique is: select thin magnetic eyelet diameter to be the collection thread device of 65 μm, determine grain 10, cocoon 3 ~ 5 is joined newly in center, and manually determining grain adds thread, beating temperature 87 ~ 93 DEG C, filature soup temperature 33 ~ 39 DEG C, the filature speed of a motor vehicle 80 ~ 100 revs/min, flow 700 mL/min, croisure length 14 cm;
5) by little silk sheet in vacuum barrel with dewing under 0.082MPa vacuum pressure 4 times, workshop temperature 25 ~ 27 DEG C with humidity 65%, compartment temperature 38 ~ 40 DEG C and return into the large silk sheet that girth is 1.3 ~ 1.5 meters under humidity 39%, the speed of a motor vehicle 140 ~ 145 revs/min, 30 minutes are balanced 75% time in temperature 26 ~ 28 DEG C and humidity, then carry out volume inspection, hank knotting, color matching, packing, member, be produced into the ultra-fine raw silk of 9/11D specification;
6) twist with 6 ultra-fine raw silks of 9/11D specification and become warp, twist with 8 ultra-fine raw silks of 9/11D specification and become parallel, Weaving-machine is woven into ultrafine mulberry silk fabric, and its process conditions are: Winding Tension is 1.5 ~ 3.5 CN, become cylinder thread tension be in 2.5 ~ 4 CN, warping skewer tension force be 0.5 ~ 1.3 CN, be organized as 2/2 twill, density high density 26# reed, through close be 52 ~ 54 pieces/centimetre, filling density is 43 ~ 45 pieces/centimetre;
7) ultrafine mulberry silk fabric is carried out coming unstuck white silk in vain through first white silk, again white silk, washing and oven dry four steps, first experienced technique is: 98 ~ 100 DEG C, leaching 1 ~ 1.5 hour in the soda ash aqueous solution of concentration 1.5 grams per liter, practicing technique is again: soak 1 ~ 1.5 hour at 98 ~ 100 DEG C in 2.8 grams per liter soda ash, 0.5 grams per liter sodium hydrosulfite and 2 grams per liter sodium silicate and 4 grams per liter dispersant solution, washing process is: rinsing 10 minutes in 50 ~ 60 DEG C of clear water, and stoving process is: with blanket collator at vacuum pressure 3 kgf/cm
2lower drying also arranges;
8) automatic color separation retouches original text on computers, according to fixed flower pattern making sheet;
9) with thickener PS-14 for medium, acid red, Huang, blue dyestuff selected by being fully in harmonious proportion, modulate percentage by weight 0.5 ~ 8% acid red, Huang, blue dye paste respectively;
10) ultrafine mulberry silk fabric is fixed on dyeing machine, by institute's making sheet, mill base is imprinted on white ultrafine mulberry silk fabric, becomes various floral pattern;
11) use continuous steaming machine in pressure 0.5 kgf/cm
2lower decatize 45 min, is bonded to dyestuff on fiber;
12) use clear water rinsing, remove the slurry, the loose colour that evaporate on rear fabric;
13) extra-fine mulberry silk twill product is made in arrangement.
Described " ultra-fine element " synthesizes imidazoles by weight: o-phenylenediamine: POCl
3: HCl=3:1:30:0.1 mixes, back flow reaction 1 ~ 1.5 hour at 60 ~ 85 DEG C, purifies with recrystallization method, vacuumize and obtaining.
The beneficial effect that the present invention has is:
Adopt the extra-fine mulberry silk twill that the present invention produces, chromaticness is bright-coloured, and have unique gloss and local flavor, crease-resistant, dyeability is good, and COLOR FASTNESS is high, and economic worth is large; Traditional Silk Industry can be promoted simultaneously, meet the multiple demand of domestic and international market.
