Description

Technical Field

[0001] The present application relates to the technical field of fabrics, and more specifically, to a highly breathable textured fabric and a preparation process thereof. Background Art

[0002] Textured fabrics feature a unique pattern and texture, typically produced using high-density textile techniques. Patterns can be striped, checked, floral, geometric, or a variety of other forms, and the texture can be smooth, rough, loose, or glossy. Compared to ordinary textiles, textured fabrics offer a more layered feel, feel softer and more comfortable, and offer a more visually appealing aesthetic.

[0003] Textured fabrics include film-embossed fabrics, three-dimensional knitted fabrics, embossed fabrics and other fabrics with a textured feel. Due to their prominent structure, textured fabrics are more likely to have defects such as non-breathability and rough feel. Summary of the Invention

[0004] In order to improve the defects of textured fabrics such as being thick or airtight, the present application provides a highly breathable textured fabric and a preparation process thereof, which adopts the following technical solutions:

[0005] In a first aspect, the present application provides a highly breathable textured fabric, comprising a fabric layer and a finishing layer, wherein the fabric layer is a hemp fabric layer, and the finishing layer is prepared by a finishing liquid, wherein the finishing liquid comprises the following materials in parts by weight:

[0006] 2-3 parts collagen;

[0007] 7-8 parts of polyvinyl alcohol;

[0008] 100 parts of solvent.

[0009] By adopting the above technical solution, hemp fiber can keep the skin dry for a long time and has good air permeability. Hemp fiber has a softer feel, is less likely to have problems such as uneven strands and excessive hairiness, and has excellent antibacterial effect. Therefore, hemp is preferably used as the main material of the textured fabric, which can give the textured fabric better air permeability and antibacterial effect.

[0010] It is preferred to use collagen and polyvinyl alcohol to prepare the finishing liquid. Collagen and polyvinyl alcohol can form a thin film on the surface of the hemp fabric layer. Collagen can adhere to the surface of the hemp fiber to form a film, which can cover the fuzz defects on the surface of the hemp fabric layer to improve the roughness of the hemp fabric layer, effectively improve the feel of the textured fabric, and improve the wearing performance of the textured fabric.

[0011] Optionally, the collagen is collagen extracted by fermentation.

[0012] By adopting the above technical solution, it is preferred to use fermentation method to extract collagen. The fermentation method can make collagen obtain a looser and more porous structure, so that the film formed by the finishing liquid has more air permeable channels, thereby improving the air permeability of the textured fabric.

[0013] Optionally, the preparation method of the collagen is as follows: dry fish skin is mixed with sterile water, a culture solution of Bacillus Velez (FEL-BM21) is added, and fermentation treatment is performed to obtain pretreated fish skin; the pretreated fish skin is mixed with an acid solution, standing for extraction, centrifugation, retaining the supernatant, salt precipitation, collecting the precipitate, dissolving the precipitate in an acid solution, dialyzing the acid solution with distilled water until no salt ions are present, and freeze-drying to obtain the collagen.

[0014] By adopting the above technical solution, preferably using Bacillus Velez to ferment the fish skin, during the fermentation process, Bacillus Velez can decompose non-collagen components in the fish skin while being less susceptible to decomposing collagen. Non-collagen components interspersed with collagen are decomposed, thereby giving the collagen a loose, porous structure. Furthermore, the protease produced by Bacillus Velez can break down some molecular cross-links in the telopeptide region, facilitating the dissolution of collagen from the fish skin and improving the collagen extraction rate.

[0015] Optionally, the inoculation amount of the Bacillus Velez subtilis (FEL-BM21) is 10-12%.

[0016] By adopting the above technical solution, the inoculation amount of Bacillus Velez is optimized. The appropriate inoculation amount enables Bacillus Velez to multiply and grow rapidly to fully hydrolyze non-collagen substances in fish skin, thereby obtaining relatively pure, loose and porous collagen.

[0017] Optionally, the finishing solution further comprises silver nitrate.

[0018] By adopting the above technical solution, silver nitrate is added to the finishing liquid, which can be carried by collagen and loaded on the surface of the hemp fabric layer. After ultraviolet irradiation, the silver ions can migrate to the fiber surface, thereby forming silver clusters, and forming nanosilver particles on the surface of the finishing layer. In this process, more porous structures can be generated in the collagen, and air permeability channels can be added to the finishing layer to improve the breathability of the textured fabric. In addition, with the migration of silver ions, the collagen can be brought into contact and bonded to form cross-linking, which can improve the strength of the finishing layer. The introduction of nanosilver in the finishing layer can give the finishing layer excellent antibacterial properties and odor removal effects, which can reduce the odor caused by collagen and further improve the wearing performance of the textured fabric.

[0019] Optionally, the mass fraction of the silver nitrate is 0.9-1%.

[0020] By adopting the above technical solution, the amount of silver nitrate added to the finishing liquid is optimized. The appropriate amount of addition can obtain a suitable pore structure on the collagen fibers to improve the breathability of the textured fabric, and can maintain the strength of the finishing layer, which is beneficial for the finishing layer to long-term improve the feel of the textured fabric, that is, improve the wearing performance of the textured fabric.

[0021] Optionally, the finishing liquid further comprises a fragrance finishing agent.

[0022] By adopting the above technical solution, preferably adding a fragrance finishing agent to the finishing agent, the fabric can obtain better fragrance.

[0023] Optionally, the hemp fabric layer is a hemp fabric layer pretreated with a modifier, and the modifier includes apple polyphenols and chitosan.

[0024] By adopting the above technical solution, it is preferred to use apple polyphenol and chitosan to pretreat the hemp fabric. Chitosan has better adhesion and can graft apple polyphenol to the surface of the hemp fabric. It can also consume the negative charge on the surface of the hemp fabric layer to improve the affinity between the fabric layer and the apple polyphenol, so that the apple polyphenol can be firmly grafted to the surface of the hemp fabric, so that the hemp fabric layer obtains excellent antibacterial effect. Through the introduction of apple polyphenol, the phenolic hydroxyl groups in the apple polyphenol can interact with the carbonyl groups in the collagen to form hydrogen bonds, which can further improve the bonding effect between the finishing layer and the fabric layer, so that the finishing layer can fully and lastingly improve the defect of the poor feel of the hemp fabric layer. At the same time, the introduction of chitosan can also improve the bonding effect between the nanosilver particles and the fabric layer, which can further improve the bonding effect between the fabric layer and the finishing layer.

[0025] Optionally, the modifier further includes sodium alginate.

[0026] By adopting the above technical solution, sodium alginate has better moisture absorption effect, which can improve the moisture absorption effect of textured fabrics. In addition, sodium alginate can also cross-link with collagen to further improve the bonding effect between the finishing layer and the hemp fabric layer.

[0027] In a second aspect, the present application provides a method for preparing a highly breathable textured fabric, which adopts the following technical solution:

[0028] A method for preparing a highly breathable textured fabric comprises the following steps:

[0029] S1. Preparation of finishing solution: Weigh collagen, polyvinyl alcohol, and solvent in parts by weight and mix to prepare a finishing solution;

[0030] S2. Fabric preparation: Fix the hemp fabric layer on a flat receiver, place the finishing liquid in an electrospinning machine for electrospinning treatment, and prepare the product fabric.

[0031] By adopting the above technical solution, preferably using the electrospinning method to load the finishing liquid on the hemp fabric layer,

[0032] In summary, this application has the following beneficial effects:

[0033] 1. Since the present application preferably uses collagen and polyvinyl alcohol to prepare the finishing liquid, collagen and polyvinyl alcohol can form a thin film on the surface of the hemp fabric layer, and collagen can adhere to the surface of the hemp fiber to form a film, which can cover the fuzz defects on the surface of the hemp fabric layer to improve the roughness of the hemp fabric layer, effectively improve the feel of the textured fabric, and improve the wearing performance of the textured fabric.

[0034] 2. In this application, silver nitrate is added to the finishing liquid, which can be carried by collagen and loaded on the surface of the hemp fabric layer. After ultraviolet irradiation, the silver ions can migrate to the fiber surface, thereby forming silver clusters, forming nanosilver particles on the surface of the finishing layer. In this process, more porous structures can be generated in the collagen, and air permeability channels can be added in the finishing layer to improve the air permeability of the textured fabric. In addition, with the migration of silver ions, the collagen can be brought into contact and bonded to form cross-linking, which can improve the strength of the finishing layer. The introduction of nanosilver in the finishing layer can give the finishing layer excellent antibacterial properties and odor removal effects, reduce the odor caused by collagen, and further improve the wearing performance of the textured fabric.

[0035] 3. This application preferably uses apple polyphenol and chitosan to pretreat the hemp fabric. Chitosan has excellent adhesion and can graft apple polyphenol onto the surface of the hemp fabric. It can also consume the negative charge on the surface of the hemp fabric layer to improve the affinity between the fabric layer and the apple polyphenol, so that the apple polyphenol can be firmly grafted onto the surface of the hemp fabric, and the hemp fabric layer can obtain excellent antibacterial effect. Through the introduction of apple polyphenol, the phenolic hydroxyl groups in the apple polyphenol can interact with the carbonyl groups in the collagen to form hydrogen bonds, which can further improve the bonding effect between the finishing layer and the fabric layer, so that the finishing layer can fully and lastingly improve the defect of the poor feel of the hemp fabric layer. DETAILED DESCRIPTION

[0036] The present application is further described in detail below with reference to the embodiments.

[0037] Preparation Example

[0038] Collagen Preparation Example

[0039] Preparation Example 1

[0040] Under sterile conditions, Bacillus velezensis (FEL-BM21) was inoculated into nutrient broth and activated for 24 hours (20°C, 140 rpm). One mL of the activated culture was inoculated into another 100 mL bottle of nutrient broth and rejuvenated for 28 hours (20°C, 200 rpm) to obtain a seed culture. The seed culture was centrifuged at 4224 × g for 10 minutes to obtain well-grown Bacillus velezensis cells. The cells were then washed with sterile water and centrifuged three times (6600 × g, 5 minutes) to remove excess nutrients. Finally, the cells were transferred to a conical flask containing 100 mL of sterile water to obtain a new seed culture.

[0041] Dried tilapia skin was mixed with sterile water at a ratio of 1:20 (g / mL), and 12% (v / v) fresh seed culture medium was added. The mixture was fermented at 20°C and 200 rpm for 12 hours. After fermentation, the mixture was filtered and washed to obtain the pretreated fish skin. The pretreated fish skin was mixed with 0.5 mol / L acetic acid solution at a ratio of 1:60 (w / v), stirred, and allowed to stand for 48 hours. The mixture was then centrifuged (8000×g, 4°C, 10 min) to collect the supernatant. NaCl was slowly added to the supernatant to a final concentration of 0.9 mol / L (while stirring), allowed to stand at 4°C for 30 minutes, and centrifuged (10000×g, 4°C, 30 min) to collect the precipitate. The precipitate was dissolved in 0.5 mol / L acetic acid solution, dialyzed against 0.1 mol / L acetic acid solution and then distilled water until no salt ions were present, and freeze-dried to obtain collagen.

[0042] Preparation Example 2

[0043] The difference from Preparation Example 1 is: dried tilapia skin is mixed with sterilized water at a ratio of 1:20 (g / mL), 12% (v / v) new seed culture fluid is added, and fermented under 20 ℃ and 200r / min conditions for 12h. After fermentation, filter, wash, and obtain pre-treated fish skin. Pre-treated fish skin is mixed with 0.5mol / L acetic acid solution in a ratio of 1:60 (w / v), stirred, left standstill for 48h, centrifuged (8000×g, 4 ℃, 10min), and supernatant is collected. Slowly adding NaCl to the supernatant to a final concentration of 0.9mol / L (stirring while adding), left standstill for 30min at 4 ℃, centrifuged (10000×g, 4 ℃, 30min), and precipitate is collected. 0.5mol / L acetic acid solution dissolves the precipitate, dialyzes with 0.1mol / L acetic acid solution and distilled water successively, until no salt ions exist, and freeze-dried to obtain collagen.

[0091] Comparative Example

[0092] Comparative Example 1

[0093] The difference between this comparative example and Example 3 is that the finishing liquid in this comparative example does not include polyvinyl alcohol.

[0094] Performance testing

[0095] (1) Air permeability test: The air permeability of the linen fabric before and after compounding was tested using a fabric air permeability meter in accordance with GB / T543-1997 “Determination of air permeability of fabrics”.

[0096] (2) Friction coefficient test: According to FZ / T01054-2012 “Test method for friction performance of fabric surface”, the friction coefficient of the fabric before and after compounding was tested using a fabric style meter.

[0097] (3) Softness test: Softness is tested through subjective evaluation. Five testers are asked to perform hand feel tests on the linen fabric before and after finishing and evaluate the softness level.

[0098] (4) Washability: Use a Y(B)089A fully automatic shrinkage machine to wash the fabric in a washing machine with AATCC 1993 standard detergent. Record the number of washes until the collagen absorption peak disappears.

[0099] Table 2 Performance test

[0100]

[0101] The hand feel grade of the comparative example 1 is grade 2, and the hand feel grade of the fabrics in Examples 1-10 is grade 5.

[0102] Combining the performance test comparison in Table 2, we can find that:

[0103] 1. By comparing Examples 1-3 with Comparative Example 1, it can be found that the air permeability and friction coefficient of the product fabrics prepared in Examples 1-3 are reduced, and the softness is improved. This shows that collagen and polyvinyl alcohol are selected to prepare the finishing liquid in this application. Collagen and polyvinyl alcohol can form a thin film on the surface of the hemp fabric layer. Collagen can adhere to the surface of the hemp fiber to form a film, which can cover the fuzz defects on the surface of the hemp fabric layer, thereby improving the roughness of the hemp fabric layer, effectively improving the feel of the textured fabric, and improving the wearing performance of the textured fabric.

[0104] 2. In conjunction with Example 4-5 and Example 3, it can be found that the air permeability of the product fabric obtained in Example 4-5 is improved, and the friction coefficient is decreased. This explanation shows that fermentation method is adopted to extract collagen in the present application. In the fermentation method, Bacillus Velez can decompose the non-collagen components in the fish skin, and is difficult for decomposing collagen. The non-collagen components mixed in the collagen are decomposed, and then the collagen is obtained to obtain a loose, porous structure, and then the film formed by the finishing liquid has more air permeable channels, thereby improving the air permeability of the textured fabric.

[0105] 3. By comparing Examples 6-7 with Example 3, it can be found that the air permeability of the fabrics of the products prepared in Examples 6-7 is improved and the friction coefficient is reduced. This shows that the silver nitrate added to the finishing liquid in this application can be carried by collagen and loaded on the surface of the hemp fabric layer. After ultraviolet irradiation, the silver ions can migrate to the fiber surface, thereby forming silver clusters, forming nanosilver particles on the surface of the finishing layer. In this process, more porous structures can be generated in the collagen, and air permeability channels can be increased in the finishing layer to improve the air permeability of the textured fabric. In addition, with the migration of silver ions, the collagen can be brought into contact and bonded to form cross-linking, which can improve the strength of the finishing layer. The introduction of nanosilver in the finishing layer can give the finishing layer excellent antibacterial properties and odor removal effects, can reduce the odor caused by collagen, and further improve the wearing performance of the textured fabric.

[0106] 4. By comparing Examples 9-10 with Example 3, it can be found that the water-washing resistance of the fabrics of the products prepared in Examples 9-10 is improved, while the air permeability is reduced. This indicates that in the present application, through the introduction of apple polyphenols, the phenolic hydroxyl groups in the apple polyphenols can interact with the carbonyl groups in the collagen to form hydrogen bonds, which can further improve the bonding effect between the finishing layer and the fabric layer, so that the finishing layer can fully and lastingly improve the defect of the poor hand feel of the hemp fabric layer. At the same time, the introduction of chitosan can also improve the bonding effect between the nanosilver particles and the fabric layer, which can further improve the bonding effect between the fabric layer and the finishing layer. Since the introduction of apple polyphenols, chitosan and sodium alginate increases the thickness of the finishing layer on the fabric surface, the air permeability of the fabric is reduced.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
