Description

Technical Field

[0001] This application relates to the field of fabric processing technology, and more specifically, to a peptide protein fiber fabric and its preparation method. Background Technology

[0002] Babies' skin is very delicate during infancy. Therefore, the fabric of baby clothes at this stage is mainly made of pure cotton, especially the underwear. The reason is that pure cotton has good moisture absorption and breathability, which can effectively regulate the humidity and temperature of the baby's skin. Even when the baby is active and sweats easily, it can quickly absorb sweat, keep the baby dry, and prevent prickly heat or diaper rash. Secondly, pure cotton fabric is soft and skin-friendly, and will not cause any friction or irritation to the baby's delicate skin.

[0003] However, when babies lie flat playing or sleeping, all-cotton fabrics tend to ride up, exposing their tummy and causing discomfort. This is mainly because the inner layer of the cotton fabric has insufficient friction against the skin, causing the clothing to ride up easily during baby's movements. Additionally, dry weather can generate static electricity, making the cotton fabric even more prone to clinging to the body and riding up. To prevent this, baby clothing is often made into onesies, which effectively prevents the clothes from riding up. However, onesies are inconvenient and cumbersome to wear. Therefore, there is a need for a fabric that won't ride up. Summary of the Invention

[0004] To address the problem that existing all-cotton fabrics tend to ride up when worn, this application provides a peptide protein fiber fabric and its preparation method.

[0005] In a first aspect, this application provides a peptide-containing protein fiber fabric, which adopts the following technical solution:

[0006] A peptide-containing protein fiber fabric is prepared from the following raw materials by weight percentage:

[0007] Modal fiber 40-50%

[0008] Polyvinyl alcohol fiber 35-40%

[0009] The remainder is spandex;

[0010] The polyvinyl alcohol fiber is prepared by the following method:

[0011] 1) Dissolve polyvinyl alcohol in an organic solvent, then add spinning solution to obtain a polyvinyl alcohol solution;

[0012] 2) Add vinyl polysiloxane, solid filler, silane coupling agent, peptide protein, fatty acid sulfonyl ester and hydroxyethyl cellulose to polyvinyl alcohol solvent to obtain a mixture;

[0013] 3) After the mixture is spun using a wet spinning process, it is coagulated and drawn in a coagulation bath, then aldehyde-treated in an acetal solution, oiled, dried, and crimped to obtain polyvinyl alcohol fiber.

[0014] By adopting the above technical solution, the prepared peptide protein fiber fabric has good softness, skin-friendliness, breathability, and moisture absorption, while also having good friction with the skin and will not shift when worn.

[0015] Modal fiber improves the skin-friendliness, breathability, and comfort of fabrics, but it is prone to deformation and shrinkage during use. Spandex has good elasticity; adding spandex to fabrics made with modal and polyvinyl alcohol fibers effectively improves the deformation and shrinkage issues of modal fibers. Simultaneously, the elasticity of spandex allows the fabric to adapt to the baby's movements, helping it stay close to the body without being too tight, preventing clothing from shifting due to being too tight or too loose. It also increases the friction between the fabric and the skin, preventing clothing from riding up during the baby's activities. While spandex is added to improve the fabric's elasticity, its softness, skin-friendliness, and breathability are poor. Therefore, this application addresses these issues by preparing specific polyvinyl alcohol fibers to improve the fabric's softness, skin-friendliness, and breathability caused by spandex, while further increasing the friction between the material and the baby's skin to prevent the fabric from riding up.

[0016] In the preparation of polyvinyl alcohol (PVA) fibers, the addition of vinyl polysiloxanes, solid fillers, and silane coupling agents improves the surface properties and internal structure of the fibers, making them softer and smoother. The addition of peptides not only enhances the fiber's skin-friendliness but also helps improve its moisture retention, further increasing the fabric's breathability and moisture absorption, making the fibers more comfortable against the skin. The addition of solid fillers and hydroxyethyl cellulose allows PVA fibers to form a microporous structure, facilitating the expulsion of sweat and the dissipation of moisture, keeping the skin dry. Simultaneously, peptides, solid fillers, and hydroxyethyl cellulose increase the friction between PVA fibers and the skin, preventing the fabric from shifting too much against the skin. The addition of additives such as vinyl polysiloxanes improves the fabric's antistatic properties. In dry weather, the fabric is less prone to static electricity, thus avoiding the problem of clothing clinging to the body and riding up due to static electricity.

[0017] Polyvinyl alcohol (PVA) fibers prepared through a wet spinning process have a uniform cross-section and excellent surface morphology. This structure allows for a larger contact area between the fiber and the skin, resulting in stronger friction and further improving the stability of the clothing during wear. The addition of PVA fibers to modal fibers and spandex further enhances the fabric's friction against a baby's skin.

[0018] Preferably, the raw materials used to prepare the polyvinyl alcohol fiber are as follows by weight:

[0019] 20-25 parts of polyvinyl alcohol

[0020] 40-50 parts organic solvent

[0021] 10-15 parts spinning solution

[0022] 2-5 parts vinyl polysiloxane

[0023] 6-8 parts of solid filler

[0024] 1-2 parts of silane coupling agent

[0025] 10-15 parts peptide protein

[0026] 1-2 parts of fatty acid sulfonyl esters

[0027] Hydroxyethyl cellulose 2-5 parts.

[0028] By adopting the above technical solution, the weight of the raw materials used to prepare polyvinyl alcohol fiber is optimized, further improving the softness, skin-friendliness, breathability, moisture absorption, and friction of peptide protein fiber fabric.

[0029] Preferably, the solid filler is obtained by mixing shell powder, diatomaceous earth and mica powder in a weight ratio of (4-6):3:1.

[0030] By adopting the above technical solutions, the breathability, moisture wicking, and softness of polyvinyl alcohol fibers can be further improved. At the same time, the friction of polyvinyl alcohol fibers can also be increased, thereby increasing the friction of the fabric against the baby's skin and preventing the clothes from riding up.

[0031] Both shell powder and diatomaceous earth have porous structures, creating more micropores within the fibers. This facilitates the expulsion of sweat and the dissipation of moisture, thus improving the fabric's breathability and moisture absorption. Simultaneously, their low hardness enhances the softness of polyvinyl alcohol (PVA) fibers. The layered structure of mica powder gives PVA fibers good toughness, making them less prone to breakage under external forces. This increases the fiber's flexibility and impact resistance, making it less likely to break during processing or use. All three components also increase the friction of PVA fibers, enhancing the friction between the fabric and the skin and reducing clothing riding up.

[0032] Preferably, the coagulation bath consists of 50-70 g / L sulfuric acid, 90-110 g / L zinc sulfate, and 180-200 g / L sodium sulfate, with a reaction temperature of 50-60°C, a spinning rate of 50-60 m / min, and a soaking time of 10-15 s.

[0033] By adopting the above technical solution and optimizing the composition of the coagulation bath, the polyvinyl alcohol fiber structure becomes uniform and delicate, resulting in a soft and comfortable feel with good friction. Simultaneously, it ensures the formation of good air-permeable channels and moisture-absorbing structures within the polyvinyl alcohol fiber, keeping the skin dry and comfortable.

[0034] Preferably, the number-average molecular weight of the polyvinyl alcohol is 50,000 to 220,000.

[0035] By adopting the above technical solutions and optimizing the number-average molecular weight of polyvinyl alcohol, a more stable molecular chain structure can be formed, which makes the polyethylene fiber have higher softness, skin-friendliness and friction.

[0036] Preferably, the vinyl polysiloxane has a vinyl content of 0.5-2% and a number average molecular weight of 5000-20000.

[0037] By adopting the above technical solutions, optimizing the vinyl content and number-average molecular weight in vinyl polysiloxane helps to form a microporous structure inside the fiber, thereby improving the fabric's breathability. This allows the fabric to better regulate airflow, keeping the skin dry and comfortable. It also helps to avoid the problem of clothing clinging to the body and riding up due to static electricity, improving wearing comfort.

[0038] Preferably, the modal fibers are pretreated by the following method:

[0039] Immerse modal fibers in a pretreatment agent for 1-2 hours, remove and air dry to obtain pretreated modal fibers;

[0040] The pretreatment agent is obtained by mixing sodium acetate, citric acid, anionic polyacrylamide, antistatic agent and water in a weight ratio of 1:(0.4-0.6):(2-3):(1-2):15.

[0041] By employing the above technical solutions, the coefficient of friction and electrostatic effect of Modal fibers are reduced, making them easier to comb and twist, thereby improving spinning efficiency and yarn quality. Simultaneously, the mechanical strength of Modal fibers is improved. Modal fibers are made from natural wood pulp, and their structure is relatively fragile. During spinning and weaving, the fibers are easily damaged mechanically. Pretreatment can form a protective film on the fiber surface, reducing damage during subsequent processing, thus protecting the fiber structure and extending the fabric's lifespan. Organic acids such as sodium acetate and citric acid help soften the fibers, making the fabric softer and more comfortable. The addition of antistatic agents significantly reduces the static effect of the fabric, reducing discomfort during wear. Anionic polyacrylamide may adsorb onto the fiber surface, forming a protective film and reducing fiber damage during subsequent processing.

[0042] Preferably, the spandex is pretreated using the following method:

[0043] Soak the spandex fiber in a pretreatment solution, heat it to 50-60℃, soak for 3-4 hours, rinse with clean water, take it out and dry it to obtain pretreated spandex fiber.

[0044] The pretreatment solution is obtained by mixing sodium hydroxide solution (15-20% by mass), sodium alginate, water-soluble chitosan, and water in a ratio of 10:(3-5):(5-8):20.

[0045] By employing the above technical solutions, the breathability and skin-friendliness of spandex are improved. The sodium hydroxide solution in the pretreatment solution may activate the surface of the spandex, increasing its hydrophilicity and making it easier for subsequently added sodium alginate and water-soluble chitosan to bind to the fiber. Natural polymers such as sodium alginate and water-soluble chitosan may bind to the fiber surface through chemical bonds or physical adsorption, forming a protective film that provides lubrication, softness, and protection.

[0046] Secondly, this application provides a method for preparing a peptide-containing protein fiber fabric, which adopts the following technical solution:

[0047] A method for preparing a peptide-containing protein fiber fabric includes the following preparation steps:

[0048] S1. Modal fiber, polyvinyl alcohol fiber and spandex are spun into composite yarn;

[0049] S2. Spin the composite yarn into fabric.

[0050] By adopting the above technical solution, the fabric prepared has good breathability, moisture permeability, softness and friction, and is suitable for clothing. After being made into clothing, it is not easy to ride up when the baby is lying down or moving.

[0051] Preferably, the modal fiber, the polyvinyl alcohol fiber, and the spandex all have a fineness of 1-20D.

[0052] By adopting the above technical solutions, the fineness of modal fiber, polyvinyl alcohol fiber and spandex is optimized, making the fabric softer and more delicate, improving the comfort of wearing it, and at the same time helping to increase the fabric's breathability, moisture absorption and friction.

[0053] In summary, this application has the following beneficial effects:

[0054] 1. The synergistic effect of modal fiber, modified polyvinyl alcohol fiber and spandex in the fabric makes the fabric soft, skin-friendly and breathable and moisture-wicking, while also having good friction, which can ensure that the fabric will not easily ride up when the baby is moving, thus effectively protecting the baby's belly from getting cold.

[0055] 2. By adding components such as vinyl polysiloxane, solid fillers, and silane coupling agents, the surface properties and internal structure of the fibers can be improved, making them softer and smoother. Peptides help enhance the moisture-retaining properties of the fibers, further improving the breathability and moisture absorption of the fabric, making the fibers more comfortable when in contact with the skin. The addition of solid fillers and hydroxyethyl cellulose allows polyvinyl alcohol fibers to form a microporous structure, which is conducive to the wicking away of sweat and the dissipation of moisture, keeping the skin dry. At the same time, peptides, solid fillers, and hydroxyethyl cellulose can increase the friction between polyvinyl alcohol fibers and the skin, thus making the fabric less likely to shift against the skin. Vinyl polysiloxane can improve the antistatic properties of the fabric. In dry weather, the fabric is less prone to static electricity, thus avoiding the problem of clothing sticking to the body and riding up due to static electricity. Detailed Implementation
