Description

TECHNICAL FIELD

[0001] The present application relates to the field of viscose gauze, in particular to a soft viscose gauze and a preparation method thereof. BACKGROUND

[0002] In the field of textiles, as people's living standards continue to improve, the quality and performance requirements of textiles are also increasingly improved. Viscose fiber belongs to a kind of lyocell fiber, which is made of natural wood pulp through dissolution and regeneration, and belongs to regenerated cellulose fiber in man-made fiber. As a new type of regenerated cellulose fiber, it has been widely used in the textile industry due to its good moisture absorption, air permeability and drape, etc. It can not only be used for daily clothing and other textiles, but also has great potential in the field of mask gauze. In the use scene of mask, people pay great attention to the softness of mask gauze, because the gauze directly contacts the skin, and its softness will greatly affect the use experience.

[0003] However, the rigidity of viscose fiber itself makes the fabric feel hard, and lacks enough softness, so that the mask gauze cannot fit the facial contour. However, the softness of the existing viscose fabric is still insufficient to meet the needs of the market. Therefore, the present application provides a soft viscose gauze and a preparation method thereof. SUMMARY

[0004] In order to improve the softness of viscose gauze, the present application provides a soft viscose gauze and a preparation method thereof.

[0005] In the first aspect, the present application provides a preparation method of a soft viscose gauze, which adopts the following technical scheme: A preparation method of a soft viscose gauze, comprising the following steps: S1: opening the viscose fiber, and performing first carding and laying the web to obtain a viscose fiber web; S2: performing second carding on the viscose fiber web, and adding a coiled yarn web, so that the viscose fiber web is evenly dropped on both sides of the yarn web to obtain an initial gauze, and then performing hydroentanglement treatment on the initial gauze to obtain a viscose gauze; S3: soaking the viscose gauze in a softener for 20-30 min, then washing, drying, and coiling to obtain a soft viscose gauze.

[0006] By adopting the technical scheme, in the preparation process of the soft Tencel gauze, the Tencel fibers are first opened, the block structure of the Tencel fibers is broken, the Tencel fibers are arranged in one direction through carding to form a uniform Tencel fiber web, the yarn web is added through the second carding to serve as an intermediate support layer to form a “sandwich” structure with the Tencel fiber web, and the Tencel fiber web and the yarn web are tightly combined through physical entanglement through water jet treatment to make the Tencel gauze, and finally the Tencel gauze is soaked in a softener to make the softener molecules fully penetrate into the interior of the fibers to reduce the friction coefficient between the fibers, thereby significantly improving the softness of the Tencel gauze, and the soft Tencel gauze is prepared. When it is applied to a mask cloth, it feels soft, can closely fit the facial contour, and the multi-layer gauze structure can absorb more essence liquid to reduce the probability of essence liquid dripping.

[0007] Preferably, the softener is at least one of polyether-amino co-modified silicone oil and fatty acid methyl ester sulfonate.

[0008] Preferably, the softener is polyether-amino co-modified silicone oil.

[0009] By adopting the technical scheme, the amino group in the polyether-amino co-modified silicone oil has strong polarity and can form hydrogen bonds or ionic bonds with the Tencel fibers to make the silicone oil main chain directionally adsorb on the surface of the Tencel fibers, thereby significantly reducing the static friction coefficient and the dynamic friction coefficient of the limiting part to give the Tencel gauze a smooth and fluffy hand feeling. The presence of the polyether segment can penetrate into the gap of the Tencel fibers during the water jet treatment to form an elastic crosslinked network and enhance the tear resistance of the Tencel mask cloth.

[0010] The sulfonic acid group of the fatty acid methyl ester sulfonate can significantly reduce the surface tension of the aqueous solution, enhance the wetting and penetration ability of the Tencel fibers, fully swell the non-crystalline region of the fibers, and weaken the hydrogen bond network. Moreover, the calcium soap dispersion particle of the fatty acid methyl ester sulfonate is more than 10 times that of traditional LAS, the calcium ions or magnesium ions in the pretreatment solution are chelated, the deposition of soap scum on the surface of the fibers during the water jet or washing process is reduced, and the probability of the Tencel gauze becoming hard and hard is reduced. At the same time, the lubricating effect of the fatty acid methyl ester sulfonate can reduce the friction between the fibers and inhibit the microfiber shedding caused by mechanical force.

[0011] Due to the presence of the double functional groups in the polyether-amino co-modified silicone oil, the amino group is firmly adsorbed by hydrogen bonds or ionic bonds, the polyether segment provides hydrophilicity, the balance between softness and hydrophilicity is achieved, and the polyether segment serves as an internal emulsifier, so that no additional emulsifier needs to be added, and the emulsion stability is high. Therefore, the polyether-amino co-modified silicone oil is preferably used as the softener.

[0012] Preferably, the concentration of the polyether-amino co-modified silicone oil is 1-3 wt%.

[0013] By adopting the above technical scheme, when the concentration of the polyether-amino co-modified silicone oil is too low, a continuous film cannot be formed on the surface of the Tencel fiber, resulting in a significant decrease in soft and smooth effect, and the hydrophilic effect of the polyether segment is weakened, resulting in a decrease in the moisture absorption capacity of the Tencel gauze. When the concentration of the polyether-amino co-modified silicone oil is too high, the excess polyether-amino co-modified silicone oil will block the pores of the Tencel fiber, resulting in a "false slip" phenomenon of the Tencel gauze, destroying the fluffiness of the Tencel fiber, and possibly causing the hydrophilicity of the Tencel gauze to decrease due to the high proportion of hydrophobic siloxane segments, resulting in a decrease in the moisture absorption capacity.

[0014] Preferably, in S3, a penetrating agent is also added, and the penetrating agent is at least one of isomeric tridecanol polyoxyethylene ether and fatty alcohol polyoxyethylene ether.

[0015] Preferably, the penetrating agent is isomeric tridecanol polyoxyethylene ether.

[0016] By adopting the above technical scheme, the addition of the penetrating agent helps to improve the penetration of the softener in the Tencel gauze. The alkyl chain of isomeric tridecanol in isomeric tridecanol polyoxyethylene ether contains multiple small branches, which can significantly reduce steric hindrance, making it easier to insert into the gap of Tencel fiber, and the polar ethylene oxide chain can form hydrogen bonds with water molecules, enhancing hydrophilicity, while reducing the surface tension of the solution, thereby promoting the penetration of the softener solution into the internal micropores of the Tencel fiber.

[0017] The hydrophobic group in the fatty alcohol polyoxyethylene ether can be adsorbed on the surface of the Tencel fiber, then form hydrogen bonds with water molecules through ether bonds, destroy the hydrophobic layer through solubilization, form hydrophilic channels, and accelerate the softener to be evenly covered on the surface of the Tencel fiber by reducing the contact angle.

[0018] The polyoxyethylene chain of the isomeric tridecanol polyoxyethylene ether and the polyether chain in the polyether-amino co-modified silicone oil form a hydrogen bond network through ether bond oxygen atoms, the formed hydrogen bond network forms a "dynamic water reservoir" on the surface of the Tencel fiber, and multiple hydrogen bonds are formed between the ether bond oxygen atoms and water molecules and polar components (such as hyaluronic acid, ceramide) in the essence. At the same time, the isomeric tridecanol polyoxyethylene ether cooperates with the polar hydroxyl group in the amino silicone oil at the oil-water interface to form a tightly arranged high-strength interface film, controlling the slow release of the essence in the film. In addition, the branched alkyl group of the isomeric tridecanol polyoxyethylene ether and the methyl / long-chain alkyl group in the silicone oil are associated through van der Waals force, promoting the uniform spreading of the polyether-amino co-modified silicone oil on the surface of the Tencel fiber. The isomeric tridecanol of the isomeric tridecanol polyoxyethylene ether can wrap the residual hydrophobic amino silicone oil to form micelles, improve the solubility of the residual in the aqueous solution, and reduce the residual of the amino in the Tencel gauze.

[0019] Preferably, the concentration of the isomeric tridecanol polyoxyethylene ether is 0.1-0.3wt%.

[0020] By adopting the above technical solution, when the concentration of isomeric tridecanol polyoxyethylene ether is too low, the surface tension of the solution cannot be effectively reduced, resulting in weakened wetting and penetrating ability of the structure of fibers, micropores, etc., and the permeability of the softener in the Tencel fiber cannot be effectively improved. When the concentration of isomeric tridecanol polyoxyethylene ether is too high, excessive isomeric tridecanol polyoxyethylene ether will form too many micelles, and part of the molecules will be wrapped by the micelles and cannot contact the interface, so that the proportion of effective molecules actually participating in the penetration is reduced, and a "micelle shielding effect" occurs.

[0021] Preferably, the mass ratio of the Tencel fiber to the gauze is 1.8-2.2:1.

[0022] By adopting the above technical solution, when the Tencel fiber is too little, the Tencel fiber net is too thin, which cannot completely cover the surface of the gauze, resulting in a significant decrease in the softness of the Tencel gauze. When the Tencel fiber is too much, the proportion of the gauze is too small, which cannot effectively support the Tencel fiber, resulting in a decrease in the interlayer bonding force between the Tencel fiber net and the gauze, and a decrease in the tear resistance of the Tencel gauze.

[0023] Preferably, the gauze is made of blended Tencel fiber and cotton fiber, and the blending ratio of the Tencel fiber to the cotton fiber is 1:1.5-2.

[0024] By adopting the above technical solution, when the blending ratio of the Tencel fiber is too low, the proportion of the cotton fiber is too high, resulting in a decrease in the softness of the Tencel gauze. When the blending ratio of the Tencel fiber is too high, the supporting force of the gauze is insufficient, resulting in a decrease in the interlayer bonding force between the Tencel fiber net and the gauze, and a decrease in the tear resistance of the Tencel gauze.

[0025] In a second aspect, the present application provides a soft Tencel gauze, which adopts the following technical solution: A soft Tencel gauze is prepared by the preparation method of the soft Tencel gauze according to any one of claims 1-9.

[0026] In summary, the present application has at least one of the following beneficial technical effects: 1. The present application immerses the Tencel gauze in a softener, so that the softener molecules fully penetrate into the interior of the fibers, the friction coefficient between the fibers is reduced, the softness of the Tencel gauze is significantly improved, and the soft Tencel gauze is prepared. When it is applied to a mask cloth, it has a soft touch, can closely fit the facial contour, and the multi-layer gauze structure can absorb more essence liquid, reducing the probability of essence liquid dripping; 2. The application uses polyether-amino co-modified silicone oil as a softener. The amino group in the polyether-amino co-modified silicone oil has strong polarity, which can form hydrogen bonds or ionic bonds with Tencel fibers, so that the silicone oil main chain is oriented and adsorbed on the surface of Tencel fibers, significantly reducing the static friction coefficient and dynamic friction coefficient of the limiting piece, thereby giving Tencel gauze a smooth and fluffy hand feel. The presence of polyether segments can penetrate into the gaps of Tencel fibers during hydroentanglement treatment, forming an elastic crosslinked network to enhance the tear resistance of Tencel film cloth. 3. The application uses isomeric tridecanol polyoxyethylene ether as a penetrant. The polyoxyethylene chain of isomeric tridecanol polyoxyethylene ether forms a hydrogen bond network with the polyether chain in the polyether-amino co-modified silicone oil through ether bond oxygen atoms. The formed hydrogen bond network forms a "dynamic water reservoir" on the surface of Tencel fibers, and through ether bond oxygen atoms and water molecules and polar components (such as hyaluronic acid and ceramide) in the essence, multiple hydrogen bonds are formed to control the slow release of essence in the mask. BRIEF DESCRIPTION OF DRAWINGS

[0027] Figure 1 is a structural schematic diagram of soft Tencel gauze in the embodiments of the application.

[0028] In the figure: 1, Tencel fiber; 2, gauze. DETAILED DESCRIPTION

[0029] The raw materials in the application include the following parts: Fatty acid methyl ester sulfonate: commercially available product with CAS number 93348-22-2; Polyether-amino co-modified silicone oil: The polyether-amino co-modified silicone oil with model number HB-301N from Yantai Hanbang New Material Co., Ltd. is taken as an example in the application; Fatty alcohol polyoxyethylene ether: commercially available product with CAS number 52292-17-8; Isomeric tridecanol polyoxyethylene ether: commercially available product with CAS number 9043-30-5.

[0030] The application is further described in detail in combination with examples and comparative examples.

[0031] Example 1 A method for preparing soft Tencel gauze, comprising the following steps: S1: opening Tencel fibers, and carrying out first carding and laying, to obtain a Tencel fiber web; S2: carrying out second carding on the Tencel fiber web, and adding a gauze roll to make the Tencel fiber web evenly fall on both sides of the gauze, to obtain an initial gauze, and then carrying out hydroentanglement treatment on the initial gauze to obtain Tencel gauze; S3: soaking the Tencel gauze in a softener for 20-30 min, then carrying out water washing, drying, and roll-off to obtain soft Tencel gauze.

[0032] The mass ratio of the Tencel fiber web to the yarn web is 2:1. The yarn cloth is made of Tencel fiber and cotton fiber, and the blending ratio of the Tencel fiber to the cotton fiber is 1:1.8. The softener is 2wt% polyether-amino co-modified silicone oil.

[0033] Example 2 Example 2 is based on the preparation method of Example 1, and 2wt% polyether-amino co-modified silicone oil is replaced by fatty acid methyl ester sulfonate, and the rest of the conditions remain unchanged.

[0034] Comparative Example 1 Comparative Example 1 is based on the preparation method of Example 1, and S3 is removed, and the rest of the conditions remain unchanged.

[0035] Comparative Example 2 Comparative Example 2 is based on the preparation method of Example 1, and the Tencel fiber after opening is soaked in the softener for 20-30min in S1. After drying, the Tencel fiber web is obtained by carding and laying. Then the Tencel fiber web is carded again, and the yarn web is added to make the Tencel fiber web evenly fall on both sides of the yarn web to obtain the initial yarn cloth. Then the initial yarn cloth is treated by water jet to obtain the soft Tencel yarn cloth.

[0036] Performance detection test The soft Tencel yarn cloths of Examples 1-2 and Comparative Examples 1-2 are analyzed, and the specific detection method is as follows: 1. Softness The softness of the soft Tencel yarn cloth is tested according to the national standard GB / T 18318.1-2009.

[0037] 2. Tear resistance The tear resistance of the Tencel yarn cloth is tested by the impact pendulum method according to the national standard GB / T 3917.1-2009.

[0038] According to the above detection method, the test results of Examples 1-2 and Comparative Examples 1-2 are obtained, as shown in Table 1 below.

[0039] Table 1 Performance detection table of Examples 1-2 and Comparative Examples 1-2 Project Example 1 Example 2 Comparative Example 1 Comparative Example 2 Softness / cm 3.24 3.32 5.03 4.51 Warp strength / N 15.76 14.84 9.43 10.96 Weft strength / N 15.32 13.98 8.46 10.68 As shown in Table 1, the softness and tear resistance of the Tencel yarn cloth obtained by Examples 1-2 are better than those of Comparative Examples 1-2, because the softener can penetrate into the gap between the fibers, reduce the friction coefficient between the fibers, and thus significantly improve the softness of the Tencel yarn cloth. However, the softener treatment of the Tencel fiber after opening will affect the subsequent carding and laying and water jet reinforcement of the Tencel fiber, resulting in a significant decrease in the tear resistance of the Tencel yarn cloth.

[0040] Example 3-4 Example 3-4 is based on the preparation method of Example 1, and the concentration of the polyether-amino co-modified silicone oil is adjusted. The specific adjustment is shown in Table 2.

[0041] Comparative Example 3-4 Comparative Example 3-4 is based on the preparation method of Example 1, and the concentration of the polyether-amino co-modified silicone oil is adjusted. The specific adjustment is shown in Table 2.

[0042] Performance detection test The soft Tencel gauze of Example 1, Example 3-4 and Comparative Example 3-4 is analyzed, and the specific detection method is as follows: hygroscopicity According to the national standard GB / T 24218.6-2010, the wet rate of Tencel gauze is tested, and the hygroscopicity of Tencel gauze is reflected by the wet rate.

[0043] According to the above detection method, the test results of Example 1, Example 3-4 and Comparative Example 3-4 are obtained, as shown in Table 2 below.

[0044] Table 2: Concentration of polyether-amino co-modified silicone oil and performance detection table of Example 1, Example 3-4 and Comparative Example 3-4 As shown in Table 2, by comparing Example 1, Example 3-4 and Comparative Example 3-4, when the concentration of polyether-amino co-modified silicone oil is 1-3wt%, especially when the concentration of polyether-amino co-modified silicone oil is 2wt%, the softness and hygroscopicity of the obtained Tencel gauze are optimal. This may be because when the concentration of polyether-amino co-modified silicone oil is too low, a continuous film cannot be formed on the surface of Tencel fiber, resulting in a decrease in the softness of Tencel gauze, and the hydrophilic effect of the polyether segment is weakened, resulting in a decrease in the hygroscopicity of Tencel gauze; when the concentration of polyether-amino co-modified silicone oil is too high, the pores of Tencel fiber are blocked, and the hydrophilicity of Tencel gauze may be reduced due to the high proportion of hydrophobic siloxane segment, resulting in a decrease in the hygroscopicity of Tencel gauze.

[0045] Example 5 Example 5 is based on the preparation method of Example 1. In S3, 0.2wt% isomerized tridecanol polyoxyethylene ether is added and blended with 2wt% polyether-amino co-modified silicone oil to obtain a mixed solution. Then, the Tencel gauze is soaked in the mixed solution for 20-30min, dried and rolled to obtain soft Tencel gauze. The rest of the conditions remain unchanged.

[0046] Example 6 Example 6 is prepared based on the preparation method of Example 5, 0.2wt% isomerized tridecanol polyoxyethylene ether is replaced by 0.2wt% fatty alcohol polyoxyethylene ether, and the rest of the conditions remain unchanged.

[0047] The soft Tencel gauze of Examples 5-6 is subjected to the above performance test, and the test results are shown in Table 3.

[0048] Table 3 Performance test table of Example 1 and Examples 5-6 As shown in Table 3, comparing Comparative Example 1 and Examples 5-6, the softness and liquid carrying rate of the Tencel gauze obtained by Examples 5-6 are better than that of Example 1, which may be because the addition of the penetrant can improve the penetration of the softener in the Tencel gauze, thereby improving the softness of the Tencel gauze. Among them, the polyoxyethylene chain in isomerized tridecanol polyoxyethylene ether and the polyether chain segment in polyether-amino co-modified silicone oil can form a hydrogen bond network through ether bond oxygen atoms, and the hydrogen bond network formed on the surface of Tencel fiber forms a "dynamic water reservoir", thereby significantly improving the liquid carrying rate of the Tencel gauze.

[0049] Examples 7-8 Examples 7-8 are prepared based on the preparation method of Example 5, and the concentration of isomerized tridecanol polyoxyethylene ether is adjusted, and the specific adjustment is shown in Table 4.

[0050] Comparative Examples 5-6 Comparative Examples 5-6 are prepared based on the preparation method of Example 5, and the concentration of isomerized tridecanol polyoxyethylene ether is adjusted, and the specific adjustment is shown in Table 4.

[0051] The soft Tencel fiber of Examples 7-8 and Comparative Examples 5-6 is subjected to the above performance test, and the test results are shown in Table 4.

[0052] Table 4 Isomerized tridecanol polyoxyethylene ether concentration and performance test table of Example 5, Examples 7-8 and Comparative Examples 5-6 As shown in Table 4, it can be seen from Comparative Example 5, Examples 7-8 and Comparative Examples 5-6 that when the concentration of isomeric tridecanol polyoxyethylene ether is 0.1-0.3 wt%, especially when the concentration of isomeric tridecanol polyoxyethylene ether is 0.2 wt%, the softness of the spunlace lyocell fabric obtained is optimal, which can be due to that when the concentration of isomeric tridecanol polyoxyethylene ether is too low, the surface tension of the solution cannot be effectively reduced, resulting in weakened wetting and penetration of the solution to the fibers and thus the penetration of the softener into the lyocell fibers cannot be effectively improved; when the concentration of isomeric tridecanol polyoxyethylene ether is too high, too many micelles are formed, and some molecules cannot contact the interface due to being wrapped by the micelles, so that the proportion of effective molecules actually participating in the penetration is reduced, and thus the softness of the spunlace lyocell fabric is reduced.

[0053] Examples 9-10 Examples 9-10 are prepared based on the preparation method of Example 1, and the mass ratio of the lyocell fiber web and the yarn web is adjusted, and the specific adjustment is shown in Table 5.

[0054] Comparative Examples 7-8 Comparative Examples 7-8 are prepared based on the preparation method of Example 1, and the mass ratio of the lyocell fiber web and the yarn web is adjusted, and the specific adjustment is shown in Table 5.

[0055] The soft spunlace lyocell fabric of Examples 9-10 and Comparative Examples 7-8 is subjected to the above performance detection, and the detection results are shown in Table 5.

[0056] Table 5 Mass ratio of lyocell fiber web and yarn web and performance detection table of Example 1, Examples 9-10 and Comparative Examples 7-8 As shown in Table 5, it can be seen from Comparative Example 1, Examples 9-10 and Comparative Examples 7-8 that when the mass ratio of the lyocell fiber web and the yarn web is 1.8-2.2:1, especially when the mass ratio of the lyocell fiber web and the yarn web is 2:1, the softness and interlayer bonding force of the spunlace lyocell fabric obtained are ideal, which can be due to that when the lyocell fiber is too little, the lyocell fiber web is too thin to completely cover the surface of the yarn web, resulting in reduced softness of the spunlace lyocell fabric; when the lyocell fiber is too much, the yarn web cannot effectively bear the lyocell fiber, resulting in reduced interlayer bonding force of the lyocell fiber and the yarn web and thus reduced tear strength of the spunlace lyocell fabric.

[0057] Examples 11-12 Examples 11-12 are prepared based on the preparation method of Example 1, and the blending ratio of the lyocell fiber and the cotton fiber is adjusted, and the specific adjustment is shown in Table 6.

[0058] Comparative Examples 9-10 Comparative Examples 9-10 are prepared based on the preparation method of Example 1, and the blending ratio of the lyocell fiber and the cotton fiber is adjusted, and the specific adjustment is shown in Table 6.

[0059] The above performance tests were conducted on Examples 11-12 and Comparative Examples 9-10, and the test results are shown in Table 6.

[0060] Table 6: Blend ratio of Tencel fiber and cotton fiber and performance test table of Examples 1, 11-12 and Comparative Examples 9-10 As shown in Table 6, it can be seen from Comparative Examples 1, Examples 11-12 and Comparative Examples 9-10 that when the blend ratio of Tencel fiber and cotton fiber is 1:1.5-2, especially when the blend ratio of Tencel fiber and cotton fiber is 1:1.8, the softness and tear resistance of the Tencel gauze are in an ideal state, which may be because when the blend ratio of Tencel fiber is too low, the proportion of cotton fiber is too high, resulting in a decrease in the softness of the Tencel gauze; when the blend ratio of Tencel fiber is too high, it will result in insufficient support of the gauze, resulting in a decrease in the interlayer bonding force of the Tencel fiber gauze and the gauze, resulting in a decrease in the tear resistance of the Tencel gauze.
