Description

Technical Field

[0001] This application relates to the field of textile fabric technology, and more specifically, to an antibacterial fabric containing seaweed fibers and a method for preparing the same. Background Technology

[0002] Regenerated cellulose fiber is a textile fiber made from natural cellulose by altering its physical structure. Regenerated cellulose fiber possesses excellent properties such as environmental friendliness, breathability, moisture absorption, skin-friendliness, and dyeability, making it widely used in fabric manufacturing. Fabrics made from regenerated cellulose fiber are widely used in pajamas, underwear, and other intimate apparel.

[0003] However, with global warming, especially the significant increase in average summer temperatures in various regions, it is easy to sweat outdoors. After a large amount of sweat is excreted, it is easy to soak up the clothes underneath, thereby reducing the comfort of wearing clothes.

[0004] Meanwhile, clothes with sweat that are not washed in time are prone to bacterial growth, which can lead to discoloration, odor, easy wear and tear, and damage, reducing the safety and durability of underwear. Further research is needed to address this issue. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides an antibacterial fabric containing seaweed fibers and a method for preparing the same.

[0006] In a first aspect, this application provides an antibacterial fabric containing seaweed fiber, which is obtained by knitting antibacterial yarn. The antibacterial yarn is composed of 85-92% by mass of regenerated cellulose fiber and 8-15% by mass of seaweed fiber, and the antibacterial yarn is 30-40 count.

[0007] In the above-mentioned scheme, seaweed fiber has excellent moisture absorption properties. It exerts its moisture absorption properties through contact with the skin and actively releases seaweed components, thereby improving the antibacterial and deodorizing effects of the antibacterial fabric. Therefore, the antibacterial yarn formed by using regenerated cellulose fiber and seaweed fiber has excellent antibacterial properties. The antibacterial fabric obtained by knitting has excellent breathability, antibacterial properties and moisture wicking properties. When wearing the clothing, it can quickly wick away sweat and reduce the growth of bacteria on the clothes. The antibacterial property of this application is as high as 99%.

[0008] Furthermore, by combining 85-92% regenerated cellulose fiber and 8-15% seaweed fiber, an antibacterial yarn is obtained, which combines the comprehensive properties of both. Therefore, the resulting fabric has the characteristics of better strength, antibacterial properties, softness and comfort. Moreover, the antibacterial yarn is selected with a count of 30-40. Under this range of composition and count of the antibacterial yarn, the resulting antibacterial fabric has better abrasion resistance, antibacterial properties and softness, reducing the occurrence of pilling and bacterial growth, and providing better deodorizing and moisture-wicking effects, thereby improving the safety and durability of the clothing during use.

[0009] Preferably, the fabric weight is 100-150 g / m². 3 .

[0010] When using a weight of 100-150g / m³ 3 At the same time, its fabric has good breathability, moisture wicking, softness and comfort as well as abrasion resistance, further reducing the possibility of bacteria growth in antibacterial fabrics and improving the safety, durability and comfort of the clothing.

[0011] Preferably, the antibacterial yarn is treated with a toughening agent, which is composed of raw materials in parts by weight:

[0012] 20-30 parts water

[0013] 1-5 parts of environmentally friendly organic solvent

[0014] Antibacterial thickener 0.8-1.7 parts

[0015] Emulsifier 0.5-1 part

[0016] Ammonium persulfate 0.1-0.3 parts

[0017] 0.01-0.08 parts of methoxy polyethylene glycol acrylate, 0.5-1.8 parts of methacryloyl ethyl sulfobetaine, and 0.1-0.5 parts of (3-methacryloyloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methyl.

[0018] While seaweed fiber can improve antibacterial and moisture-wicking properties, it is relatively weak. Therefore, antibacterial yarns produced from seaweed are prone to problems such as fraying and fiber breakage during the weaving process, resulting in pilling on the surface of the fabric. Furthermore, even after long-term use, underwear made from antibacterial fabrics is still prone to bacterial growth, wear, and pilling, thus reducing the durability and safety of the antibacterial fabric.

[0019] Therefore, this application further employs a toughening treatment agent to improve the bonding tightness between the seaweed fiber and regenerated cellulose in the antibacterial yarn, reducing the possibility of wear and pilling in the resulting antibacterial fabric after long-term use, and improving the durability of the antibacterial fabric. Simultaneously, it provides better antibacterial effect, reducing the likelihood of bacterial growth, wear, and pilling after the fabric is exposed to sweat.

[0020] Specifically, methoxy polyethylene glycol acrylate can enhance tensile strength and ductility, and improve the toughness of the antibacterial treatment agent after film formation; while methacryloyl ethyl sulfobetaine has wettability, dispersibility and antibacterial properties, and the methacrylic acid groups it contains can copolymerize with methoxy polyethylene glycol acrylate and (3-methacryloyloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methyl to form a macromolecular polymer with better adhesion, film-forming properties and toughness after film formation.

[0021] The (3-methacryloyloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methyl molecule contains hydroxyl, siloxy, and acrylate groups. It further reacts with methacryloyl ethyl sulfobetaine and methoxy polyethylene glycol acrylate to form a macromolecular polymer with good adhesion and film-forming properties.

[0022] Therefore, by copolymerizing methoxy polyethylene glycol acrylate, (3-methacryloyloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methyl, and methoxy polyethylene glycol acrylate to form a macromolecular polymer, and then interacting with an antibacterial tackifier, the resulting toughening agent possesses superior antibacterial properties, adhesion, film-forming properties, and film toughness. Thus, compared to antibacterial yarn treatment, it can penetrate into the gaps between seaweed fibers and cellulose fibers, and after curing, it stabilizes the adhesion of seaweed fibers and cellulose fibers, forming an antibacterial toughening film on the surface of the antibacterial yarn. This reduces the likelihood of wear, pilling, and damage in the resulting antibacterial fabric, improving its durability.

[0023] In addition, since both antibacterial thickeners and methacryloyl ethyl sulfobetaine have good antibacterial properties, the two work together to give the toughening treatment agent good antibacterial properties. When treated with antibacterial yarn, the antibacterial yarn has both good antibacterial properties and toughness, reducing the possibility of wear, breakage, pilling and other issues, and improving the safety and durability of antibacterial fabrics.

[0024] Furthermore, the copolymerization of methoxy polyethylene glycol acrylate, (3-methacryloyloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methyl, and methoxy polyethylene glycol acrylate forms a macromolecular polymer that is resistant to sweat, reducing the impact of sweat on the antibacterial fabric. Simultaneously, the addition of antibacterial thickeners and methacryloxyethyl sulfobetaine further enhances the antibacterial properties of the antibacterial yarn, resulting in an antibacterial fabric that combines excellent sweat resistance, antibacterial properties, and abrasion resistance, reducing the likelihood of bacterial growth, easy wear, and pilling after being exposed to sweat.

[0025] The toughening agent is used to treat antibacterial yarns as follows:

[0026] Weigh out ammonium persulfate, (3-methacryloyloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methyl, methoxy polyethylene glycol acrylate, methacryloyl ethyl sulfobetaine, emulsifier, and water, mix them evenly, heat to 62-70℃, react for 1-2 hours, then add antibacterial thickener and environmentally friendly organic solvent, stir for 1-2 hours to obtain toughening agent; soak the weighed antibacterial yarn in toughening agent for 10-30 minutes, dry it, and obtain reinforced antibacterial yarn.

[0027] In the above process, (3-methacryloyloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methyl, methoxy polyethylene glycol acrylate, and methacryloyl ethyl sulfobetaine are compounded and, with the assistance of water, emulsifier, and ammonium persulfate, heated to allow the active groups to react and copolymerize further. Then, an antibacterial thickener is added to further thicken the toughening system. When the resulting treatment agent is used to treat antibacterial yarn, the toughness of the antibacterial yarn is further improved, and the resulting antibacterial fabric has better antibacterial properties, abrasion resistance, and soft hand feel.

[0028] Preferably, the antibacterial thickener is composed of one or more of mussel adhesive protein, polyglutamic acid, and chitosan derivatives.

[0029] Mussel adhesive protein, polyglutamic acid, and chitosan derivatives all have certain antibacterial effects and, when filled into toughening agents, play a role in increasing viscosity, further improving the toughness and antibacterial properties of the antibacterial yarn after toughening treatment.

[0030] Preferably, the antibacterial thickener is composed of mussel adhesive protein, polyglutamic acid, and chitosan derivatives.

[0031] When mussel adhesive protein, polyglutamic acid, and chitosan derivatives are used in combination, they achieve better antibacterial and thickening effects. When the resulting toughening agent is used to treat antibacterial yarn, the antibacterial yarn possesses both excellent antibacterial properties and toughness. This reduces the possibility of antibacterial yarn breakage, pilling, and wear during the production or use of the resulting antibacterial fabric, while also giving the antibacterial fabric better antibacterial properties.

[0032] Preferably, the weight ratio of mussel adhesive protein, polyglutamic acid, and chitosan derivative is (3-8):3:(2-7).

[0033] Preferably, the chitosan derivative is sulfonated chitosan and / or methacrylamide chitosan.

[0034] The weight ratio of sulfonated chitosan to methacrylamide chitosan is 1:(1-3).

[0035] Preferably, the emulsifier is one or more of the following: cocamidopropyl betaine, OP-10, OP-20, and sodium dodecyl sulfate.

[0036] Preferably, the environmentally friendly organic solvent is anhydrous ethanol and / or dipropylene glycol dimethyl ether.

[0037] Secondly, this application provides a method for preparing an antibacterial fabric containing seaweed fiber, comprising the following steps: twisting seaweed fiber and regenerated cellulose fiber to obtain antibacterial yarn; and then knitting the antibacterial yarn to obtain antibacterial fabric.

[0038] In summary, this application has the following beneficial effects:

[0039] 1. The antibacterial yarn, obtained by combining 85-92% regenerated cellulose fiber and 8-15% seaweed fiber, possesses the combined properties of both. Therefore, the resulting fabric has excellent strength, antibacterial properties, softness, and comfort. Furthermore, the antibacterial yarn is selected with a count of 30-40. Under this composition and count range, the resulting antibacterial fabric has excellent abrasion resistance, antibacterial properties, and softness, reducing pilling and bacterial growth. It also provides excellent deodorizing and moisture-wicking effects, improving the safety and durability of the clothing during use.

[0040] 2. Through the copolymerization reaction of methoxy polyethylene glycol acrylate, (3-methacryloyloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methyl, and methoxy polyethylene glycol acrylate, a macromolecular polymer is formed. This polymer then interacts with an antibacterial tackifier, resulting in a toughening agent with superior antibacterial properties, adhesion, film-forming properties, and film toughness. Therefore, compared to antibacterial yarns, this agent can penetrate into the gaps between seaweed fibers and cellulose fibers. After curing, it stabilizes the adhesion of seaweed fibers and cellulose fibers and forms an antibacterial toughening film on the surface of the antibacterial yarn. This reduces the possibility of wear, pilling, and damage in the resulting antibacterial fabric, thus improving its durability. Detailed Implementation

[0098] Performance testing

[0099] Test method / test method Antibacterial properties: The test was conducted in accordance with GB / T 20944.2-2007. The control group was fabric with 100% regenerated cellulose fiber by mass. The antibacterial rate increase of the antibacterial fabrics of Examples 1-20 and Comparative Examples 1-2 after the addition of seaweed fiber was calculated compared with the control group.

[0100] The wear-resistant microfiber fabrics obtained in Examples 1-20 and Comparative Examples 1-3 were cut into 4 groups of samples. The samples were soaked in artificial sweat with a pH of 6 for 2 hours, wrung out, and the humidity of the samples was measured to be 37%. The samples were then air-dried for 36 hours at a temperature of 30°C, a humidity of 62%, and a wind speed of 0.5 m / s to obtain the test samples.

[0101] (1) Integrity: Observe whether there are spots, obvious discoloration or other phenomena on the surface of the test sample. If the above phenomena are present, it is recorded as unqualified. If there are no such phenomena, it is recorded as qualified.

[0102] (2) Wear degree: Refer to ISO12947-1-1998 and use Martindale wear tester to test the test samples. The pressure is 10 kPa and the speed is 50 r / min. The friction is carried out for 1100, 2000, 3000 and 4500 times respectively. Then the wear degree is evaluated. The wear degree is classified as slight wear, moderate wear and severe wear. When the breakage occurs, it is recorded as wear breakage and no further friction test is carried out. The relevant wear degree is recorded.

[0103] The specific details of the above tests are shown in Table 2;

[0104] Table 2. Experimental data for Examples 1-20 and Comparative Examples 1-3

[0105]

[0106]

[0107]

[0108] Based on Example 1 and Comparative Examples 1-2, and in conjunction with Table 2, it can be seen that the antibacterial rate increase of Comparative Example 1 is higher than that of Example 1. However, Comparative Example 1 shows signs of wear after 3000 rubs, while Example 1 only shows signs of wear after 4500 rubs. The antibacterial rate increase of Comparative Example 2 is lower than that of Example 1, and the wear degree of Comparative Example 2 is the same as that of the Example during 1100-4500 rubs. This indicates that the antibacterial fabric prepared using the seaweed fiber content range of this application has both good antibacterial properties and tear resistance.

[0109] Combining Examples 1 and Examples 4-6 with Table 2, it can be seen that the increase in antibacterial rate in Examples 4-6 is slightly lower than that in Example 1. However, the wear degree of Examples 4-6 during the 1100-4500 friction cycles is better than that in Example 1. This indicates that using the toughening agent prepared in this application to treat antibacterial yarn can reduce wear and other phenomena.

[0110] Combining Examples 5 and 10-12 with Table 2, it can be seen that the antibacterial rate increase of Examples 10-12 is higher than that of Example 5. Furthermore, the wear degree of Examples 10-12 during the 1100-4500 friction cycles is the same as that of Example 5. This indicates that the use of mussel adhesive protein, polyglutamic acid, and chitosan derivatives all have a synergistic antibacterial effect, further improving the antibacterial properties of the antibacterial fabric while maintaining good tear resistance.

[0111] Combining Examples 11 and 15 with Table 2, it can be seen that the antibacterial rate increase in Example 15 is higher than that in Example 11. Furthermore, the wear degree of Example 15 during the 1100-4500 friction cycles is the same as that in Example 11. This indicates that the use of sulfonated chitosan and methacrylamide chitosan has a synergistic antibacterial effect. In combination with mussel adhesive protein, polyglutamic acid, etc., the antibacterial yarn treated with toughening agent may break or wear, thus giving the antibacterial fabric both good antibacterial properties and abrasion resistance.

[0112] As can be seen from Structural Examples 4 and Examples 16-20, and in conjunction with Table 2, the wear degree of Examples 16-20 during the 1100-4500 friction cycles was as severe as that of Example 4, and the increase in antibacterial rate was lower than that of Example 4. This indicates that when 3-methacryloyloxy-2-hydroxypropoxy)propylbis(trimethylsiloxy)methyl, methoxy polyethylene glycol acrylate, methacryloyl ethyl sulfobetaine, and antibacterial tackifier are combined and work together, the resulting toughening and antibacterial treatment agent has a better toughening effect on antibacterial yarns, reducing the possibility of antibacterial fabrics being corroded by sweat, resulting in breakage, wear, bacterial growth, pilling, etc.

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.
