Description

Technical Field

[0001] This application relates to the field of textile fabrics, and more specifically, to a soft, skin-friendly fabric containing protein components, its preparation process, and its application. Background Technology

[0002] Common soft and skin-friendly fabrics include pure cotton and modal cotton, which offer good wearing comfort and are therefore widely used in close-fitting clothing.

[0003] Among them, pure cotton fabric has good softness, skin-friendliness, comfort, and breathability, but its elasticity is low and it is prone to shrinkage and deformation after washing. Modal fabric is a new type of regenerated fiber. Compared with pure cotton fabric, it has a soft and smooth feel, good breathability, moisture absorption, and wrinkle resistance. However, modal fabric also has low elasticity and is prone to deformation after long-term wear, resulting in insufficient support and stability. To further improve the problem of modal fabric's easy deformation and insufficient support and stability, a blending process is generally used to add highly elastic spandex fibers to modal fabric. Although the addition of spandex fibers improves the elasticity of the resulting soft and skin-friendly fabric, the resulting soft and skin-friendly fabric still has low elasticity and is prone to deformation after long-term wear. Therefore, the current soft and skin-friendly fabrics still need further improvement. Summary of the Invention

[0004] To address the problem that current soft and skin-friendly fabrics have low resilience and are prone to deformation after prolonged wear, this application provides a soft and skin-friendly fabric containing protein components, its preparation process, and its application.

[0005] In a first aspect, this application provides a soft and skin-friendly fabric containing protein components, employing the following technical solution: a soft and skin-friendly fabric containing protein components, knitted from composite yarn, wherein the composite yarn is obtained by blending fibers in the following mass percentages:

[0006]

[0007] The viscose protein fiber is composed of cashmere protein fiber, corn protein fiber and silkworm pupa protein fiber.

[0008] By adopting the above technical solution, the protein-containing soft and skin-friendly fabric of this application not only has good softness, skin-friendliness, comfort, and breathability, but also good resilience. It is not easy to deform after long-term wear and has good support and stability for the human body. Due to its high protein content, it fits the human skin when worn, which can play a good role in skin-friendliness and moisturization, without irritating the skin or causing a tight feeling. It is suitable for close-fitting clothing, such as underwear, briefs, children's clothing, sportswear, etc.

[0009] Modal fiber is a new type of regenerated fiber with good comfort, breathability, and softness. Using a higher proportion of Modal fiber can significantly improve the softness and skin-friendly properties of the resulting fabric. However, due to its relatively low overall softness and resilience, Modal fiber is prone to deformation after long-term wear, resulting in reduced support stability. Acrylic fiber, on the other hand, has good softness and fluffiness, which can improve the support stability of the resulting soft and skin-friendly fabric. Viscose fiber contains protein and has good skin-friendliness and moisturizing properties, as well as good support stability. Spandex fiber is soft and highly elastic. Therefore, further combining acrylic fiber, viscose fiber, and spandex fiber with Modal fiber creates a synergistic effect, resulting in a soft and skin-friendly fabric that is not only soft and skin-friendly but also has good resilience, is not easily deformed, and provides good support stability for the human body.

[0010] To further enhance the softness and skin-friendliness of the fabric, this application uses a blend of cashmere protein fiber, corn protein fiber, and silkworm pupa protein fiber as viscose protein fiber. The three fibers can produce a good blending effect, which can better enhance the support of the resulting soft and skin-friendly fabric, making the fabric less prone to deformation.

[0011] Preferably, the weight ratio of the cashmere protein fiber, the corn protein fiber, and the silkworm pupa protein fiber is 1.5-2):(0.1-0.3):(0.2-0.5).

[0012] By adopting the above technical solutions, cashmere protein fiber has good skin-friendliness and moisturizing properties and is not easy to shrink. However, compared with modal fiber, it has lower softness. Corn protein fiber has a soft and smooth feel, with a silk-like effect. It is lightweight, moisture-wicking and breathable, and rich in a variety of amino acids. Silkworm pupa protein fiber has a smooth feel like silk and a soft feel like cashmere. Silkworm pupa protein fiber contains 18 kinds of amino acids, which can play a skin-friendly and moisturizing role. Therefore, by compounding cashmere protein fiber, corn protein fiber and silkworm pupa protein fiber in a better ratio, the three produce a good synergistic effect and complementary properties. The resulting soft and skin-friendly fabric has good resilience and is not easy to deform, while also having good softness and skin-friendliness.

[0013] Preferably, the viscose fiber is a pretreated viscose fiber, which is obtained by pretreatment with a pretreatment solution consisting of the following raw materials in parts by weight:

[0014]

[0015] By adopting the above technical solution, amino-modified silicone oil possesses excellent softening properties, enabling it to impart a softer and more comfortable feel to skin-friendly fabrics. It also exhibits good wash resistance, maintaining its softness and antistatic properties even after multiple washes. Therefore, in this application, amino-modified silicone oil serves as the main softener. Adding softening agents to the amino-modified silicone oil further enhances the softness of the resulting skin-friendly fabric, reduces the steric hindrance between viscose fibers, and allows the viscose fibers to spread stably, thereby improving the overall softness of the fabric. The pretreatment solution enhances the resilience of the material. The dispersant provides good dispersion properties, enabling the pretreatment solution to penetrate and disperse evenly into the viscose fiber, thereby improving pretreatment efficiency. The stabilizer stabilizes the pretreatment solution system, allowing the pretreatment solution to penetrate stably and maximizing the expansion and fluffiness of the viscose fiber, further enhancing the resilience of the resulting soft and skin-friendly fabric. The citrate buffer solution with an optimal pH value can regulate the stability of the pretreatment solution system, ensuring the stable synergistic effect between the various raw materials for stable pretreatment of the viscose fiber.

[0016] Therefore, the pretreated viscose fibers obtained through pretreatment not only have good skin moisturizing and skin affinity, but also good softness, resilience and support stability.

[0017] Preferably, the pretreated viscose fiber is obtained by the following pretreatment steps:

[0018] A1. Add amino-modified silicone oil, softening agent, dispersant and water to the reaction equipment, mix evenly to obtain mixture A;

[0019] A2. Add a stabilizer and a citrate buffer solution with pH = 6.2-6.8 to mixture A, stir well to obtain a pretreatment solution;

[0020] A3. Dilute the pretreatment solution to a 10-20 wt% aqueous solution to obtain a pretreatment solution aqueous solution. Add the viscose fiber and the pretreatment solution aqueous solution to the reaction equipment at a weight ratio of (10-15):100, soak, wash with water, and steam-set to obtain pretreated viscose fiber.

[0021] By adopting the above technical solution, amino-modified silicone oil, softening agent and dispersant are first added to water to prepare a uniformly mixed mixture A. Then, stabilizer and citrate buffer solution are added to mixture A to adjust the system stability of the pretreatment solution. The pretreatment solution is then diluted to the usage ratio and soaked in viscose fiber to allow the pretreatment solution to penetrate and disperse evenly into the gaps of the viscose fiber, thereby adsorbing and modifying the surface of the viscose fiber. After washing with water and steam setting, the pretreated viscose fiber remains fluffy and soft, thus obtaining pretreated viscose fiber.

[0022] Preferably, the softening agent is composed of polydimethyl diallyl ammonium chloride and polyethylene glycol glycidyl ether in a weight ratio of 1:(0.3-0.6).

[0023] By adopting the above technical solution, polydimethyldiallyl ammonium chloride, as a nonionic emulsifier and antistatic agent, can further improve the softness and fiber stretch of the obtained viscose fiber. Polyethylene glycol glycidyl ether has soft molecular chain segments, which can enhance the penetration of the pretreatment solution. When polydimethyldiallyl ammonium chloride and polyethylene glycol glycidyl ether are compounded in a better ratio, the two can produce a good synergistic effect, which can enhance the adsorption and surface modification of amino-modified silicone oil on viscose fiber, while allowing the modified viscose fiber to maintain a greater degree of stretch between fibers. This improves the softness of the obtained soft and skin-friendly fabric while also improving its resilience.

[0024] Preferably, the dispersant is composed of fatty amine polyoxyethylene ether and glyceryl cocoate in a weight ratio of (0.2-0.5):1.

[0025] By adopting the above technical solution, using fatty amine polyoxyethylene ether and glyceryl cocoate in a better ratio as dispersants, the two produce a good synergistic effect, which can better improve the dispersion and penetration performance of the pretreatment liquid, and further improve the softness and resilience of the resulting soft and skin-friendly fabric.

[0026] Preferably, the stabilizer is composed of maleic anhydride-acrylamide copolymer and hydroxypropyltrimethylammonium chloride in a weight ratio of 1:(0.1-0.3).

[0027] By adopting the above technical solution, the optimal dosage of maleic anhydride-acrylamide copolymer and hydroxypropyltrimethylammonium chloride has good suspension and dispersion stability, which enables the pretreatment solution to be uniformly and fully impregnated with viscose fibers, thereby improving the treatment efficiency of the pretreatment solution on viscose fibers and further improving the softness and resilience of the modified viscose fibers.

[0028] Preferably, the soaking temperature in step A3 is 20-35℃ and the soaking time is 20-40 minutes.

[0029] By adopting the above technical solution, the optimal soaking time and soaking temperature can improve the treatment efficiency of the pretreatment solution on viscose fibers.

[0030] Secondly, this application provides a method for preparing a soft and skin-friendly fabric containing protein components, using the following technical solution:

[0031] A method for preparing a soft and skin-friendly fabric containing protein components includes the following steps:

[0032] S1. Modal fiber, acrylic fiber and spandex fiber are opened and carded to obtain pretreated fiber.

[0033] S2. Opening and carding treatment of viscose protein fibers;

[0034] S3. The pretreated fiber and the treated viscose protein fiber yarn are mixed and drawn, roving, spinning and winding processes are carried out to obtain composite yarn.

[0035] S4. Knit the composite yarn to obtain a soft and skin-friendly fabric.

[0036] By adopting the above technical solution, this application mixes modal fiber, spandex fiber and acrylic fiber, processes viscose protein fiber separately, and then mixes the two in the proportions of this application, and processes them into roving, spinning and winding to obtain composite yarn. The prepared composite yarn has good softness and resilience. After knitting, the resulting soft and skin-friendly fabric has good softness and skin-friendliness, as well as good resilience, is not easy to deform, and has good support and stability for the human body.

[0037] Thirdly, this application provides an application of a soft, skin-friendly fabric containing protein components, employing the following technical solution:

[0038] The application of a soft and skin-friendly fabric containing protein components can be used in underwear, briefs, children's clothing, and sportswear.

[0039] By adopting the above technical solution, the soft and skin-friendly fabric obtained in this application is suitable for underwear, children's clothing, sportswear, etc. due to its good softness, skin-friendliness and elasticity.

[0040] In summary, this application has the following beneficial effects:

[0041] 1. The soft and skin-friendly fabric containing protein components of this application is made by blending and knitting modal fiber, acrylic fiber, viscose protein fiber and spandex fiber in a relatively high amount. Among them, the viscose protein fiber is composed of cashmere protein fiber, corn protein fiber and silkworm pupa protein fiber, which has a high protein content, good softness, skin-friendliness, and support, and is not easily deformed. The soft and skin-friendly fabric made in this way has good softness, skin-friendliness, comfort, and elasticity, is not easily deformed after long-term use, and has good support for the human body.

[0042] 2. By using amino-modified silicone oil as the softening agent, and supplementing it with softening agents, dispersants and stabilizers, a high-performance pretreatment solution is prepared to pretreat the surface of viscose fibers. The resulting pretreated viscose fibers have good softness and fluffiness, are not easily deformed during use, and have good resilience.

[0043] 3. By using a more optimized ratio of polydimethyldiallylammonium chloride and polyethylene glycol glycidyl ether, the adsorption effect of Anji modified silicone oil on viscose fibers can be further enhanced, allowing the viscose fibers to stretch to a greater extent, thereby further improving the softness and resilience of the obtained viscose fibers.

[0044] 4. By using a preferred ratio of fatty amine polyoxyethylene ether and glyceryl cocoate as a dispersant, and further compounding a preferred ratio of maleic anhydride-acrylamide copolymer and hydroxypropyltrimethylammonium chloride as a stabilizer, a better synergistic effect with the softening agent can be achieved, further improving the softness and resilience of the obtained viscose fiber.

[0045] 5. The soft and skin-friendly fabric obtained by this application has good softness, skin-friendliness, comfort, and moisturizing properties, as well as good resilience. It is not easily deformed after long-term use and can be widely used in underwear, briefs, children's clothing, and sportswear. Detailed Implementation

[0117] Performance testing

[0118] The following tests were conducted on the performance of the soft, skin-friendly fabrics containing protein components prepared in Examples 1-18 and Comparative Examples 1-5:

[0119] (1) Softness test

[0120] According to the test method in GB / T 18318.1-2009 "Determination of bending properties of textiles", test the bending strength of the fabric (unit: mN·cm). The lower the bending strength, the better the softness. Test and record the test results.

[0121] (2) Resilience test

[0122] The prepared soft and skin-friendly fabric was stretched using a tensile testing machine, with the elongation rate controlled at 130%. A weight of 1 kg was applied to the top of the fabric and the stretch was maintained for 8 hours. After the weight was removed and the fabric was allowed to recover for 10 minutes, the deformation rate (unit: %) of the prepared soft and skin-friendly fabric was measured. The deformation rate = (length after test - initial length) / initial length * 100%. The larger the deformation rate, the worse the resilience. The test results were detected and recorded.

[0123] The following are the performance test data of the soft and skin-friendly fabrics containing protein components prepared in Examples 1-18 and Comparative Examples 1-5 of this application. Please refer to Table 4 below for details.

[0124] Table 4. Performance test data of the soft and skin-friendly fabrics containing protein components prepared in Examples 1-18 and Comparative Examples 1-5.

[0125]

[0126]

[0127] Combining Examples 1-4 and Comparative Examples 1-5 with Table 4, it can be seen that using the Modal fiber, acrylic fiber, and spandex fiber of this application in combination with viscose protein fiber composed of cashmere protein fiber, corn protein fiber, and silkworm pupa protein fiber in optimal amounts results in a soft and skin-friendly fabric containing protein components with good softness and resilience. In Comparative Examples 1-3, the optimal amounts of cashmere protein fiber, corn protein fiber, and silkworm pupa protein fiber were not used as viscose protein fibers, resulting in reduced softness and resilience in the soft and skin-friendly fabric containing protein components. In Comparative Example 4, replacing acrylic fiber with viscose protein fiber reduced resilience and improved softness, indicating that the optimal amounts of acrylic fiber and viscose protein fiber can produce a good synergistic effect, improving softness while making the soft and skin-friendly fabric less prone to deformation. In Comparative Example 5, increasing the amount of Modal fiber and decreasing the amount of viscose protein fiber slightly improved softness, but significantly increased the deformation rate.

[0128] As can be seen from Examples 2-7 and 8-18, and in conjunction with Table 4, pretreatment of viscose fibers using the pretreatment solution of this application produces pretreated viscose fibers that, when used in blending, result in a soft, skin-friendly fabric containing protein components. This fabric exhibits good softness and skin-friendliness, as well as good resilience, and is less prone to deformation during use. Furthermore, Examples 8-9 utilize a preferred ratio of polydimethyldiallyl ammonium chloride and polyethylene glycol glycidyl ether as softening agents, which further enhances the softness and resilience of the resulting soft, skin-friendly fabric. Examples 11-12 utilize a preferred ratio of fatty amine polyamide... Ethylene oxide and glyceryl cocoate are used as dispersants. In Examples 14-15, a preferred ratio of maleic anhydride-acrylamide copolymer and hydroxypropyltrimethylammonium chloride are used as stabilizers, which can further improve the softness and resilience of the prepared soft and skin-friendly fabric. In Example 17, the stabilizer is replaced with a softening agent in an equal amount, and in Example 18, the stabilizer is replaced with a softening agent in an equal amount. The softness and resilience of the prepared soft and skin-friendly fabric are reduced. This shows that the softening agent, dispersant and stabilizer of this application can produce a good compound synergistic effect to improve the softness and resilience of the soft and skin-friendly fabric prepared in this application.

[0129] The soft and skin-friendly fabric obtained in this application contains protein components. Since proteins contain a variety of amino acids, they can protect and moisturize the skin. The soft and skin-friendly fabric obtained in this application has good comfort, breathability, softness, and moisturizing properties. At the same time, it is not easily deformed and can be used in underwear, briefs, children's clothing, and sportswear, providing good support and stability for the human body.

[0130] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
