Description

Technical Field

[0001] The present invention belongs to the field of textile processing, and in particular relates to an anti-wrinkle silk / submicron fiber mosaic spun yarn and fabric, as well as a preparation method, a device and applications. Background Art

[0002] As a major silk producer, China generates a significant amount of silk waste each year. While the filaments of silk can be directly used to make high-end silk fabrics, a significant amount of short fibers remain. Recycling these short fibers for use in the silk spinning process to produce silk fabrics aligns with the nation's commitment to green development. Silk fabrics are popular among consumers for their breathability, lightness, and smooth feel.

[0003] However, compared to wool and synthetic fibers, silk fibroin lacks covalent crosslinks between its molecular chains. In the amorphous regions of silk fibroin, the primary force between its molecular chains is weak hydrogen bonds, making it less able to resist deformation under external forces and prone to sliding, deformation, and breakage. Furthermore, the low surface friction coefficient of silk fibers makes them prone to displacement when subjected to external forces. The natural hydrophilicity of silk fibers allows water molecules to easily penetrate the amorphous regions, further weakening the hydrogen bonds between the molecular chains and exacerbating further sliding. These factors contribute to the tendency of silk fabrics to wrinkle when worn, especially after washing, negatively impacting the wearing experience.

[0004] Therefore, seeking an effective anti-wrinkle finishing method for silk fabrics is an urgent problem to be solved. Chinese patent CN105648771A discloses an antibacterial and anti-wrinkle finishing process for silk / cotton blended fabrics, wherein the blended fabric is placed in a finishing liquid with a citric acid content of 50-60g / L for immersion anti-wrinkle finishing and baking, which effectively improves the anti-wrinkle effect of the fabric. Chinese patent CN108342898A discloses an anti-wrinkle treatment method for silk, wherein the silk is placed in an anti-wrinkle protective liquid containing an anti-wrinkle agent and steamed and dried, thereby achieving good anti-wrinkle finishing of the silk. However, the above-mentioned traditional finishing methods have the disadvantages of low auxiliary agent utilization, the need for large-scale finishing baths, additional consumption and affecting wearing comfort. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide wrinkle-resistant spun silk / submicron fiber inlaid yarn and fabric, as well as preparation methods, apparatus, and applications. The present invention provides an anti-wrinkle finishing method that features high anti-wrinkle agent utilization, simple processing, comfortable wear, excellent durability, and no additional consumption. This method aims to address the problem of silk fabrics wrinkling easily during wear, especially after washing. Submicron fibers loaded with anti-wrinkle agents are combined with staple fibers during the spinning and carding process. Compared to traditional anti-wrinkle finishing, the amount of anti-wrinkle agent used can be reduced by more than five times. Furthermore, the method offers significant advantages such as no need for large-scale finishing baths, simple operation, and no impact on wearer comfort.

[0006] In this invention, an anti-wrinkle agent is added to a polymer spinning solution. During the spinning and combing process, submicron fibers loaded with the anti-wrinkle agent are sprayed onto a silk web using a needleless electrospinning nozzle to produce composite fiber strips. After the spinning and weaving process, inlaid yarn or fabric is produced. A cold pad-batch finishing step effectively bonds the anti-wrinkle agent to the silk. The polymer submicron fibers have a diameter of 0-1000 nm, while the silk fibers are 38 mm-60 mm long and 10-15 μm in diameter. The active functional groups of the anti-wrinkle agent effectively covalently bond with the active groups on the silk fibroin macromolecules in the silk, securing the fiber macromolecular chains and enhancing the fiber's ability to resist deformation due to external forces, thereby improving the wrinkle resistance of the composite yarn or fabric.

[0007] The present invention provides a method for preparing wrinkle-resistant silk / submicron fiber mosaic spun yarn or fabric, comprising: (1) Mixing a polymer, a solvent, and an anti-wrinkle agent, and stirring to obtain a spinning solution; wherein the polymer comprises polyacrylonitrile; the solvent comprises N,N-dimethylformamide; the mass fraction of the polymer in the spinning solution is 8%-16%, and the mass fraction of the solvent is 84%-92%; the anti-wrinkle agent comprises one or more of polycarboxylic acids, epoxy compounds, and glyoxal; and the amount of the anti-wrinkle agent added is 10%-50% of the weight of the spinning solution; (2) combing the spun silk into a fiber web, and electrospinning the spinning solution and spraying it onto the fiber web to obtain a composite sliver; (3) spinning and finishing the composite sliver to obtain wrinkle-resistant silk / submicron fiber mosaic yarn; Alternatively, the composite sliver is subsequently spun, woven and finished to obtain a wrinkle-resistant silk / submicron fiber inlaid textile.

[0008] Furthermore, the polycarboxylic acid auxiliary agent includes citric acid and butanetetracarboxylic acid; the epoxy compound auxiliary agent includes dihydroxymethyl dihydroxyethylene urea and polyethylene glycol diglycidyl ether; and the glyoxal auxiliary agent includes polyacrylamide modified glyoxal and glyoxal-urea.

[0009] Preferably, in step (2), the spun silk after moisture conditioning is fed into the roller, and is combed into a fiber web through the cylinder and the doffer. The fiber web passes through the stripping roller and the inclined curtain, and under the suction effect of the head fan and the bundling fan or the support of the mesh curtain, the spinning solution is electrostatically spun and sprayed on the fiber web to obtain a composite raw sliver.

[0010] The silk after the humidity conditioning treatment is as follows: the silk is conditioned at a temperature of 20 to 25° C., a humidity of 80% RH or more, and a conditioning time of more than 12 hours.

[0011] Preferably, the frequency of the head fan is 20-30Hz, the frequency of the focusing fan is 15-25Hz, the speed of the inclined curtain is 90%-100% of the doffer speed, the speed of the net curtain is 95%-105% of the doffer speed, the cotton feeding speed is 0.3-0.6r / min, and the cylinder speed is 300-500r / min.

[0012] Preferably, the electrospinning process parameters in step (2) include: using a needle-free electrospinning nozzle, applying a voltage of 30-40 kV, a receiving distance from the fiber web to the spinning nozzle of 15-30 cm, a liquid supply speed of 0.5 r / min, an ambient temperature of 15-35 ° C, and a relative humidity of 70%-90% RH.

[0013] Furthermore, the needle-free electrospinning nozzle adopts a linear nozzle.

[0014] Preferably, the subsequent spinning in step (3) includes drawing, roving and spun yarn; the weaving includes knitting or weaving; and the finishing is cold rolling pile finishing.

[0015] The process parameters of the cold pad-batch finishing are as follows: placing the fabric in pure water at room temperature of 25° C., dipping and rolling, and then stacking the fabric for finishing; controlling the fabric liquid carrying rate to 70%-80%; and stacking the fabric for 12 hours for subsequent finishing and testing.

[0016] Furthermore, the post-finishing is followed by baking, wherein the baking temperature is 140-160°C.

[0017] The present invention provides a device for preparing wrinkle-resistant silk / submicron fiber inlaid spun yarn or fabric, which includes a stripping roller 4, a slanted curtain, and a conveying device, wherein a net curtain 10 is provided above the conveying device, a head fan 5 is provided on one side of the net curtain 10, and a convergence fan 12 is provided on the other side; an electrostatic spinning device is provided below the conveying device; the conveying device includes an input roller 8 and an output roller 11.

[0018] The device further comprises a roller 1, a cylinder 2 and a doffer 3; the electrostatic spinning device comprises a liquid supply device 6 and a high-voltage electrostatic generating device 7.

[0019] The device comprises a stripping roller 4, an inclined curtain and a conveying device which are sequentially connected to the fiber web.

[0020] The spun silk is fed into the roller 1, and is fully combed and evenly mixed by the cylinder 2 and the doffer 3 to form a fiber web 9. The fiber web 9 is then stripped by the stripping roller 4 and conveyed by the oblique curtain. Under the suction of the head fan and the gathering fan and the support of the mesh curtain, it is transferred forward at a uniform and appropriate speed and passes through the input roller 8 and the output roller 11 in turn. When the fiber web passes through the electrostatic spinning device, it is electrostatically spun and sprayed onto the fiber web.

[0021] The present invention provides an anti-wrinkle silk / submicron fiber mosaic spun yarn or fabric prepared by the method, wherein the total amount of submicron fibers loaded in the anti-wrinkle silk / submicron fiber mosaic spun yarn or fabric is 2‰ to 10‰ of the mass of the yarn or fabric.

[0022] The present invention provides an application of the wrinkle-resistant silk / submicron fiber mosaic spun yarn or fabric in the fields of clothing, home textiles, medical textiles, automobile interiors, intelligent wrinkle-resistant materials, etc.

[0023] The present invention achieves anti-wrinkle functional finishing of fabrics through an inlay spinning process combined with post-finishing. A polymer spinning solution loaded with an anti-wrinkle additive is uniformly deposited onto a silk net in the form of submicron fibers through electrospinning. The composite net loaded with the anti-wrinkle additive is bundled to obtain raw slivers, which are then used to prepare inlay spun yarn or fabric through a subsequent spinning process. Cold pad-batch post-finishing causes the anti-wrinkle additive to overflow into the solution, allowing the functional groups of the anti-wrinkle additive to fully react with the active groups on the silk fibroin molecular chain and produce a strong covalent bond, thereby fixing the fiber macromolecular chain and improving the fiber's ability to resist slippage and deformation under the action of external forces. Compared with traditional fabric anti-wrinkle finishing methods, the inlay spun yarn or fabric prepared by inlay spinning combined with cold pad-batch post-finishing does not require a large-scale finishing bath, can significantly reduce the amount of functional additives used, and has obvious characteristics such as simple process, environmental friendliness, and comfortable wearing. Under the same spinning and weaving processes, the composite fabric with added anti-wrinkle functional additives has a wrinkle recovery angle increased by more than 20% compared to ordinary fabrics.

[0024] Beneficial effects (1) The present invention adds an anti-wrinkle agent to a polymer spinning solution, deposits the submicron fibers loaded with the anti-wrinkle agent onto a silk net through linear needleless electrospinning, and prepares an inlaid spun composite sliver, thereby achieving a cross-scale combination between the two fibers. The inlaid spun yarn or fabric containing the anti-wrinkle agent is prepared through subsequent spinning and weaving. During the spinning process, the submicron fibers break and migrate, and are more evenly dispersed among the silk fibers in the form of broken short fragments. After cold rolling and batch finishing, the anti-wrinkle agent in the submicron fibers overflows into the solution, and the functional groups therein form a covalent cross-linked network with the active groups such as amino groups and phenolic hydroxyl groups on the silk protein molecular chain. The combination of multiple functional groups fixes the fibers, reduces fiber slippage, and thus makes the fabric less likely to deform. Even if deformation occurs, it can be restored to its original shape in a very short time.

[0025] (2) The present invention combines submicron fibers loaded with anti-wrinkle additives with spun silk to prepare inlaid spun yarns, and then prepares inlaid spun yarns or fabrics through subsequent conventional spinning processes such as drawing, roving, and spun yarns, combined with cold rolling and finishing. The inlaid spun yarns or fabrics prepared by the present invention do not require a large-scale finishing bath, and significantly reduce the amount of functional additives used, compared to traditional anti-wrinkle finishing methods. According to calculations, the total amount of submicron fibers loaded on the finished inlaid spun yarns is 2‰ to 10‰ of the yarn mass, of which the anti-wrinkle additive loading is 1 to 5 times the PAN loading, and the anti-wrinkle additive content is at most 0.008 times the mass of the inlaid spun yarns; when anti-wrinkle finishing is performed by traditional padding, the anti-wrinkle additive content is about 0.051 times the mass of the composite fabric, calculated based on the addition amount of the finishing liquid functional additive of 50-60 g / L and the fabric liquid carrying rate of 85% to 90%. The amount of anti-wrinkle additive used in the present invention can be reduced by more than 5 times. In addition, the anti-wrinkle finishing process of the present invention has the advantages of simple operation, eco-friendliness, stable function, and comfortable wearing.

[0036] The spun silk is fed into the roller 1, and is fully combed and evenly mixed by the cylinder 2 and the doffer 3 to be combed into a fiber web 9. The fiber web 9 is sequentially stripped by the stripping roller 4 and the oblique curtain, and is transferred forward at a uniform and appropriate speed under the suction effect of the head fan 5, the gathering fan 12 and the support of the mesh curtain 10, and passes through the input roller 8 and the output roller 11 in turn; when the fiber web passes through the electrostatic spinning device, the high-voltage electrostatic generating device 7 and the liquid supply device 6 are turned on for electrostatic spinning and sprayed on the fiber web to prepare a spun silk / submicron fiber inlaid spun composite sliver.

[0037] Example 2

[0038] In the embodiment 1, the steps include:

[0039] S1: Prepare 600 g of spinning solution with a mass ratio of polyacrylonitrile to N,N-dimethylformamide of 10:90, add 300 g of citric acid, and stir at room temperature for 24 h until dissolved to obtain a spinning solution.

[0040] S2: Turn on the humidifier and adjust the humidity to above 80%. Figure 3 (as shown) Pre-humidify for more than 12 hours. The temperature is controlled at 25℃.

[0041] S3: Adjust the machine and spinning process parameters as follows: the frequency of the head fan is 25Hz, the frequency of the bunching fan is 20Hz, the speed of the inclined curtain is adjusted to 96% of the doffer speed, the speed of the net curtain is adjusted to 100% of the doffer speed, the cotton feeding speed is 0.3r / min, and the cylinder speed is 400r / min.

[0042] S4: 80g of spun silk fibers are selected and made into a fiber mat, which is then fed into a carding machine. After being carded by the cylinder 2 and doffer 3, the fiber web 9 is passed through the input roller 8 and the output roller 11 in sequence under the suction of the head fan 5 and the bunching fan 12, and supported by the negative pressure suction curtain 10. The high-voltage electrostatic generator is turned on, and the electrospinning receiving distance, the electrospinning receiving voltage, and the liquid supply speed are controlled at 20cm, 35kV, and 0.5r / min. The fiber web is then bundled to obtain the mosaic-spun composite sliver.

[0043] S5: The composite sliver was drawn twice, with 8 strands drawn each time, to obtain a sliver with a grammage of 16.5 g / 5 m. The roving and spinning processes were then carried out with the following process parameters: roving grammage 5.17 g / 10 m, twist 3.5 T / m, and speed 240 r / min; and spun yarn fineness 21, twist 600 T / m, and speed 6000 r / min.

[0044] S6: The obtained composite yarn is knitted on a computer flat knitting machine into a fabric with a horizontal density of 24, a vertical density of 18.5, and a unit weight of 200 g / m2.

[0045] S7: The fabric was dipped and then padded in pure water at room temperature (25°C). The fabric was then piled to maintain a liquid pick-up rate of 70%-80%. The fabric was piled for 12 hours and then baked for 2 minutes at a temperature of 150°C. After baking, the fabric was rinsed with clean water and dried for subsequent testing.

[0046] Among them, the silk fibers treated with citric acid in the fabric are Figure 4 shown.

[0047] Citric acid covalently binds to the fibroin macromolecules in the silk spun silk. Figure 2 shown.

[0048] S8: Test the crease recovery angle of the finished fabric with reference to GB / T 3819-1997 “Determination of crease recovery of textile fabrics - Recovery angle method”.

[0049] Calculations show that the submicron fiber content in the finished inlaid yarn is 2‰ to 10‰, and the total submicron fiber content in 80g of silk inlaid yarn is at most 0.8g, including PAN submicron fibers and citric acid submicron fibers. The amount of citric acid added is 10% to 50% of the spinning solution. Calculated based on the addition of polyacrylonitrile as 10% of the spinning solution, the content of citric acid submicron fibers accounts for at most 5 / 6 of the total submicron fiber content, that is, the citric acid loading in 80g of inlaid yarn is at most 0.66g.

[0050] When applying wrinkle-resistant finishing through conventional padding, the fabric is placed in a finishing solution containing 50-60g / L of citric acid and then baked. The fabric needs to maintain a liquid pick-up rate of 85% to 90%. This means that 80g of silk fabric receives approximately 4.08g of citric acid when subjected to conventional padding. When applying wrinkle-resistant finishing through inlay spinning, the amount of citric acid used is reduced by more than five times.

[0051] Test principle and method: This experiment was conducted on a YG541E fully automatic laser fabric wrinkle elasticity tester (such as Figure 5 The crease recovery angle of the fabric is tested according to the vertical method (as shown).

[0052] (1) Cut five airfoil fabric specimens in each of the longitudinal and transverse directions according to GB / T 3819-1997. Condition the fabric specimens at 20°C and 65% RH according to the requirements of GB / T 6529-2008.

[0053] (2) Place the specimen horizontally in the specimen holder, fold the specimen in half along the folding line, and place a transparent pressure plate on the folded portion of the specimen. Operate the instrument to apply a 10N pressure hammer to the specimen for 5 minutes.

[0054] (3) After the load on the fabric sample is removed, the quick elastic crease recovery angle and the slow elastic crease recovery angle are read on the instrument respectively, and the readings are to the nearest 1°.

[0055] (4) Calculate the average value in each direction, round it to the nearest integer, and record the data in the table below.

[0056] The test results of fabric crease recovery angle are shown in Table 1.

[0061] S2: Turn on the humidifier and adjust the ambient humidity to above 80% RH. Pre-humidify the silk fibers for at least 12 hours. Control the temperature to 25°C.

[0062] S3: Adjust the machine and spinning process parameters as follows: the frequency of the head fan is 25Hz, the frequency of the bunching fan is 20Hz, the speed of the inclined curtain is adjusted to 96% of the doffer speed, the speed of the net curtain is adjusted to 100% of the doffer speed, the cotton feeding speed is 0.3r / min, and the cylinder speed is 400r / min.

[0063] S4: 90g of spun silk fibers are selected and made into a fiber mat, which is then fed into a carding machine. After being carded by the cylinder 2 and doffer 3, the fiber web 9 is passed through the input roller 8 and the output roller 11 in sequence under the suction of the head fan 5 and the bunching fan 12, and supported by the negative pressure suction curtain 10. The high-voltage electrostatic generator is turned on, the receiving distance is controlled to 20cm, and the electrospinning receiving voltage is controlled to 35kV. The fiber web is bundled to obtain the mosaic-spun composite sliver.

[0064] S5: The composite sliver was drawn twice, with 8 strands drawn each time, to obtain a sliver with a grammage of 16.5 g / 5 m. The roving and spinning processes were then carried out with the following process parameters: roving grammage 5.17 g / 10 m, twist 3.5 T / m, and speed 240 r / min; and spun yarn fineness 21, twist 600 T / m, and speed 6000 r / min.

[0065] S6: The obtained composite yarn is knitted on a computer flat knitting machine into a fabric with a horizontal density of 24, a vertical density of 18.5, and a unit weight of 200 g / m2.

[0066] S7: The fabric was cold-pad-batch finished in pure water at room temperature (25°C). The fabric was subjected to a liquid pick-up rate of 70%-80%.
