The present invention provides a yarn which is a covering yarn consisting of only silk and a yarn containing sericin. A cohesioned silk yarn is obtained by using raw silk, as a core yarn, with sericin in swollen state in reeling process at reel speed of 20 to 100 m / min, and by covering a raw silk in said reeling with a wild silk yarn, and by fusion-bonding a raw silk and a wild silk yarn by sericin. Said cohesioned silk yarn can be subjected to automatic knitting.

The invention discloses a real silk scarf fabric based on superfine mulberry silk fiber / tussah silk fiber. A sizing solution composed of dodecylazacyclohept-2-ketone, nanoparticles, binder SD28, curcumin and water is subjected to sizing treatment and then dried to obtain sizing superfine mulberry silk; the sizing superfine mulberry silk After winding, doubling and twisting, warp mulberry silk fiber and weft mulberry silk fiber are prepared, and degummed warp mulberry silk fiber and degummed weft mulberry silk fiber are obtained by refining; then the degummed warp mulberry silk fiber, degummed weft silk fiber The silk scarf fabric based on superfine mulberry silk fiber / tussah silk fiber is prepared by mixed weaving of mulberry silk fiber and degummed warp tussah silk fiber. The invention has the advantages of not easy to break during weaving, good cloth surface elasticity and good warmth retention.

The invention relates to a modified tussah silk fibroin 3D printing support and a preparation method thereof. Core part printing ink prepared by using chemically modified tussah silk fibroin nano microfibers and shell part printing ink prepared by using a chemically modified tussah silk fibroin nano microfiber / gelatin composite system are used for carrying out 3D printing to prepare a modified tussah silk fibroin 3D printing support. The compression modulus of the modified tussah silk fibroin 3D printing support is 100 to 600 MPa after soaking in genipin with the mass concentration of 0.1 to 5wt% and subjection to a cross-linking reaction for 24 h; and after culture for 10 days, the survival rate and the proliferation rate of induced pluripotent stem cells are high. The finally prepared modified tussah silk fibroin 3D printing support comprises printing lines with core-shell structures. According to the invention, the preparation method is relatively simple; and the prepared 3D printing support has excellent mechanical properties, excellent biocompatibility and good tissue repair capability.

The invention discloses an antistatic agent used for preparing wild tussah silk woolen yarn, and the antistatic performance of the brushed yarn prepared from wild tussah silk through antistatic treatment is greatly improved; the invention also discloses a wild tussah silk yarn Wool yarn and preparation method thereof, wherein nylon filament is used as core solid yarn, tussah silk / basolan wool blended roving is used as decorative yarn to obtain brushed yarn, which can give full play to the characteristics of raw materials, and the brushed yarn is soft to the touch, smooth and glutinous and has body bones , The hair feels elegant, the stiffness is good, the tensile performance is high, the anti-wrinkle performance and the anti-static performance are excellent, the dust is difficult to adhere, and the maintenance is convenient.

The invention discloses a silk flocking material and its preparation method and application. The silk flocking material comprises: a base formed of a two-dimensional material, the base having a first surface and an opposite second surface; and a plurality of The flocking fiber is fixed to the second surface of the base, and the flocking fiber is silk fluff; preferably, the silk fluff selected for the flocking fiber is mulberry silk fluff or tussah silk fluff. The invention provides a new type of silk flocking material, which provides a new fabric material for the garment industry. In addition, functional impregnation is carried out before flocking, which avoids damage to the fluff of the fabric by repeated processes, and greatly saves Enterprise cost, and increased authenticity rate.

The application of the present invention provides a novel functional finishing agent for tussah silk fabrics, a finishing method and the finished tussah silk fabrics. Leaves also contain 1,2-pentanediol and acid regulators. After tussah silk fabrics are finished with functional finishing agents, the tussah silk fabrics can be comprehensively improved in terms of weight gain, anti-ultraviolet rays, and anti-wrinkle functions. It has antibacterial function, and the functional components are firmly and persistently attached, and the decrease in mechanical strength is greatly reduced after ultraviolet radiation, which overcomes the technical problem of tussah silk fabric's ultraviolet brittleness. The technical scheme has outstanding technical advantages in terms of utilization of natural resources, simplification of process methods, optimization of input costs and finishing effect.

The invention discloses an expanded silk wadding quilt based on mulberry silk and a preparation method of the expanded silk wadding quilt. The preparation method comprises the following steps: addinga mixed solution of turmeric extract, acetic acid and carboxymethylcellulose into a degummed silk fiber solution, performing ultrasonic treatment, adding polyurea-formaldehyde and selenocysteine hydrochloride, and performing ultrasonic treatment; preparing perforated silk into silk floss pieces, and impregnating in an aqueous solution of amino polyethylene glycol so as to obtain treated silk flosspieces; putting the treated silk floss pieces into a rotatable closed container filled with a rupture disk, and expanding to obtain expanded wet silk floss pieces; dehydrating the expanded wet silk floss pieces, manually garneting, and drying to obtain expanded silkworm dried silk floss pieces; and combining and sewing the expanded silkworm dried silk floss pieces and treated tussah silk floss pieces, thereby obtaining the expanded silk wadding quilt. The porous expanded silk floss pieces with excellent service performance are successfully prepared, and the expanded silk wadding quilt has excellent antibacterial property and also has positive practical significance.

The invention provides a tussah fibroin protein microsphere including a three-dimensional porous structure and a production method thereof. The method comprises the steps of using tussah silk as raw material, degumming the tussah silk, placing degummed tussah silk into solvent to dissolve completely, dialyzing, separating, adding enzyme solution for enzymolysis, heating, and concentrating to obtain tussah fibroin protein solution; adding a foaming agent and a cross-linking agent into the tussah fibroin protein solution, standing, stirring and centrifugally separating to form tussah fibroin protein particles; and adding the tussah fibroin protein particles into sodium chloride solution, heating, stirring, centrifugally separating sediments, washing with ethyl alcohol, taking the washed sediments out, drying and placing into a low temperature environment to cool and dry, thus acquiring the tussah fibroin protein microspheres with three-dimensional porous structures. The production method provided by the invention is simple, and the produced silk fibers are good in porosity and have the properties of being skin-friendly, air and vapor permeable and adsorptive.
