The silk has the characteristics of slender shape, softness, moisture absorption, good luster and the like, and the traditional silk (four-dormancy silk or five-dormancy silk) has poor crease resistance, so that ultra-thin silk and products cannot be woven; the existing method for modifying silk fiber is to breed trimolter varieties of silkworms, such as eosin, SG, 305 and the like, and produce silk with the fineness of about 2.0 deniers; breeding a mutagenized trimolter variety silkworm, and inducing common tetramolter silk into trimolter silk by using a medicine to produce superfine silk; or inducing trimaran of tetramomnia with superfine agent (2, 4-dichloro-N-phenylimidazole) to produce superfine silk; or spraying anti-juvenile hormone on the surface of folium Mori uniformly to feed silkworm, and making common four-sleep silkworm sleep three times to produce superfine silk. However, the superfine mulberry silk has small titer and low fiber strength, so that the silk is frequently broken due to the problem of strong force in the doubling and twisting process, and the ends are frequently broken due to the factors of warp tension and reed friction in the weaving process on a loom, so that the superfine mulberry silk cannot be used for production.

The proportion can improve the infiltration effect of the superfine mulberry silk fiber, so that the sizing composition is uniformly dispersed on the surface of the fiber, and the embodiment has the advantages of improved tensile strength and good desizing effect.
In the invention, during sizing treatment, the bath ratio is 1: 5-1: 10, the temperature is 30-40 ℃, and the time is 25-30 min; and after the sizing is finished, centrifugally dewatering the superfine mulberry silk, and drying in hot air drying equipment to obtain the sized superfine mulberry silk.
In the invention, the specification of the superfine silkworm raw silk is 9/11D, the superfine silkworm raw silk is obtained by reeling a superfine silkworm monofilament with the fineness of 1.0-1.2 deniers, the raw silk is a product formed by mutually embracing a plurality of silkworm cocoon silks through reeling silk, and a fabric woven by the fine-fineness raw silk has the characteristics of strong crease resistance, rich luster, good dyeing effect and the like, but the prior art does not report that the mulberry silk with the fineness is used as scarf fabric, and the main reason is that the mechanical strength is too low on the background, so the invention solves the problems in the prior art through sizing treatment.
In the invention, spooling, doubling twisting and weaving are the prior art, spooling treatment can be carried out on a loose type spooling machine, doubling twisting treatment is carried out on a doubling twisting machine, and weaving is carried out on a weaving machine; according to the invention, the preferable warp silk fiber is 4/9/11D mulberry silk 14T/2S2Z, and the weft silk fiber is 2/9/11D mulberry silk 18T/2S 2Z.

Compared with thick denier (the filament number is 2.6-3.0 denier) silk, the fine denier (the filament number is 1.0-1.2 denier) silk has better refractive performance, strong lustrousness and strong drapability, can improve the smoothness and elasticity of silk products, and has better color brightness of printing and dyeing products. However, the superfine mulberry silk has small fineness and low fiber strength. Therefore, the yarn is frequently broken due to the problem of strong force in the doubling and twisting process, and the yarn is frequently broken due to the factors of warp tension and reed friction in the weaving process on a machine, so that the yarn cannot be used for production. Therefore, the key technology for preparing the superfine silk chiffon fabric is to improve the sizing process of the fine denier silk and improve the strength and cohesion of the superfine mulberry silk.

The breaking elongation of the raw silk before and after sizing is 15.23 percent and 16.62 percent, and the breaking elongation can be used as an indirect index for measuring the softness of silk fibers, which shows that the raw silk treated by the method has better deformation capability and better softness than that before treatment.
Soaking the mulberry silk fiber chiffon fabric in a desizing solution consisting of 46 Kg of sodium carbonate and 2955Kg of water in a real silk hanging tank at a bath ratio of 1:30, heating to 85 ℃, treating for 50min at the temperature, and discharging liquid after the treatment is finished; adding enzyme treatment solution composed of 6Kg of alkaline protease, 5Kg of sodium sulfate, 15Kg of sodium carbonate and 2974Kg of water at a bath ratio of 1:30, heating to 60 deg.C, treating at the temperature for 90min, and discharging liquid after the treatment is completed; adding 7Kg of acetic acid and 2993Kg of water at a bath ratio of 1:30, heating to 90 deg.C, and treating at this temperature for 30 min. After the treatment is finished, washing with water at 80 ℃ and 60 ℃ in sequence, washing with cold water for 3 times, and finally drying on single-roller woolen blanket equipment to obtain the superfine mulberry silk fiber silk scarf fabric, wherein the unit area weight of the chiffon fabric is 25.8 g/square meter, and the thickness of the chiffon fabric is 0.98 mm; the scarf fabric prepared after sizing is improved by 48% compared with the scarf fabric prepared without sizing by taking the folding recovery time as an auxiliary index for representing the anti-wrinkle ability; the fabric air permeability measuring instrument is adopted to test the air permeability of the scarf fabric, the average value of 3 times is 352mm/S, the flat-plate type heat preservation instrument is adopted to test the heat preservation rate of the scarf fabric, and the average value of 3 times is 22.8%, so that the scarf fabric has good air permeability and heat preservation effect; the scarf fabric prepared without sizing has poor heat retention and air permeability which are respectively 20.1% and 319 mm/S.
