Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to a breathable and antibacterial multifunctional quilt and a preparation process thereof. Background Art

[0002] Quilts are essential bedding for people to sleep and rest. A good quilt can not only improve the quality of sleep, but also improve people's sub-health conditions. Traditional quilts mainly focus on comfort and warmth, but with the improvement of people's living standards, the requirements for quilts that are closely related to life have also increased. Quilts with relatively single varieties and functions can no longer meet the needs of market development.

[0003] There are various microorganisms in nature. A warm environment can easily breed harmful bacteria and molds. There are also microorganisms in bedding that is in direct or indirect contact with people. After the bedding is eroded by bacteria and molds, it will form mildew spots, fade, produce odors, etc., which will also indirectly affect people's health and spread various diseases. Invention patent CN106263885A discloses an antibacterial and mildew-proof health care quilt and its preparation method, which mainly prepares a quilt core blank by blending functional fiber with hemp fiber and cotton fiber, and prepares a health care quilt after soaking in traditional Chinese medicine extract, sewing into shape, and putting on a cover. The obtained product has good warmth and breathability, but its antibacterial and mildew-proof effect and wear resistance are limited, and it cannot purify the space environment and improve health. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a breathable and antibacterial multifunctional quilt and a preparation process thereof.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A preparation process of a breathable antibacterial multifunctional quilt comprises the following steps:

[0007] The filling material is loaded into the fixed cover by a cover loading machine, sewn into shape by conventional sewing technology, and then loaded into the quilt cover to obtain a breathable and antibacterial multifunctional quilt.

[0008] Furthermore, the filler is one or more of cotton, polyester fiber, duck down, goose down, and silk.

[0009] Furthermore, the fixing sleeve is one of a pure cotton fixing sleeve and a polyester fixing sleeve.

[0010] Furthermore, the quilt cover is obtained by weaving polyester fibers into polyester fabrics and then sewing them.

[0011] Furthermore, the polyester fiber is prepared by the following steps:

[0012] 90-100 parts of polyester resin, 5-12 parts of modified tourmaline, 1-3 parts of antistatic agent, 0.8-1.2 parts of auxiliary agent, 0.3-0.8 parts of antioxidant and 0.3-0.8 parts of light stabilizer are weighed by weight, and all the raw materials are evenly mixed, melted, and drawn to prepare polyester fiber.

[0013] Furthermore, the polyester resin is one or more of polyethylene terephthalate resin, polybutylene terephthalate resin, and polytrimethylene terephthalate.

[0014] Furthermore, the modified tourmaline is prepared by the following steps:

[0015] Tourmaline, succinic anhydride, DMAP (4-dimethylaminopyridine) and chloroform were added to a three-necked flask under nitrogen protection, and the mixture was stirred thoroughly until uniformly mixed. The mixture was heated to 50°C with stirring and kept for reaction for 12 hours. After the reaction, the mixture was filtered, washed with saturated brine for 3 times, washed with anhydrous ethanol for 3 times, and dried at 80°C for 12 hours to obtain modified tourmaline. The dosage ratio of tourmaline, succinic anhydride, DMAP and chloroform was 15g:3g:0.73g:140mL.

[0016] Under the catalytic action of DMAP, the hydroxyl groups on the surface of tourmaline can undergo esterification reaction with succinic anhydride. The reaction process is as follows:

[0017]

[0018] Tourmaline is the general name for tourmaline minerals. It has a complex chemical composition and is a ring-structured silicate mineral characterized by boron-containing aluminum, sodium, iron, magnesium, and lithium. Tourmaline's complex and unique crystal structure gives it unique properties such as negative ion release, high wear resistance, and far-infrared radiation. It can be combined with other materials through physical or chemical methods to produce a variety of functional materials.

[0019] Tourmaline itself has the ability of permanent spontaneous polarization and does not require an additional electric field to support it, so there is no need to worry about the timeliness of the release of negative ions, and the ability to release negative ions will not be affected by washing. In addition, there is a strong electric field around tourmaline, which has an inhibitory effect on the reproduction of bacteria, and the far-infrared function of tourmaline itself can also play an antibacterial role.

[0020] After the tourmaline is modified, the carboxyl groups on the surface of the tourmaline can produce hydrogen bond interactions with the hydroxyl groups on the surface of the additives, the antioxidants and the hydroxyl groups on the surface of the light stabilizers. In addition, due to the lipophilic ester groups and carbon chains, the modified tourmaline has good compatibility with the other raw materials. As a result, the modified tourmaline can maximize its own role, stably release negative ions, and exert antibacterial and wear-resistant effects, thereby making the polyester fiber and quilt cover both antibacterial and wear-resistant, and purifying the space environment, improving human health, and being breathable and comfortable.

[0021] Furthermore, the auxiliary agent is prepared by the following steps:

[0022] S1. Place a dry three-necked flask in an ice bath under nitrogen protection, then slowly add chlorosulfonic acid, stir and cool the chlorosulfonic acid in the ice bath to below 15°C, slowly add carvacrol while stirring after 15 minutes, keep the temperature at 10°C and stir to react for 0.5h, then raise the temperature to 60°C and react for 2h. After the reaction, slowly dilute the mixture in ice water, precipitate, filter, wash the precipitate with ice water, and dry to obtain intermediate 1; the usage ratio of carvacrol to chlorosulfonic acid is 4.5g:12mL;

[0023] Under heating conditions, chlorosulfonic acid sulfonates carvacrol to obtain intermediate 1. The reaction equation is shown below:

[0024]

[0025] S2, nitrogen was blown into a dry three-necked flask for 30 minutes to expel the air and moisture in the flask, and then isothiazolinone, 1,3-propylenediamine and chloroform were added, and after stirring and dissolving, triethylamine was added, and the temperature was raised to 60°C, and the reaction was kept warm for 4 hours. After the reaction was completed, it was cooled to room temperature and distilled under reduced pressure to obtain intermediate 2; the dosage ratio of isothiazolinone, 1,3-propylenediamine, triethylamine and chloroform was 9.6mL:7.2mL:16.7mL:120mL;

[0026] Under the action of triethylamine, the molar ratio of isothiazolinone and 1,3-propylenediamine is controlled to be 1:1 and 1,3-propylenediamine is slightly excessive, and the -Cl of isothiazolinone and the -NH2 of 1,3-propylenediamine undergo nucleophilic substitution reaction. The reaction process is as follows:

[0027]

[0028] S3, nitrogen was blown into a dry three-necked flask for 30 minutes to expel air and moisture in the flask, and then intermediate 1, intermediate 2 and DMSO (dimethyl sulfoxide) were added, and after stirring and dissolving, the system was cooled to 10°C in an ice bath, and then triethylamine was slowly added. After the addition was completed, the temperature was raised to 50°C, and the reaction was kept warm for 6 hours. After the reaction was completed, it was cooled to room temperature, centrifuged, washed with anhydrous ethanol for 3 times, and dried at 80°C for 6 hours to obtain intermediate 3; the amount ratio of intermediate 1, intermediate 2, triethylamine and DMSO was 17.4g:13.8g:14.6mL:180mL;

[0029] Under heating, intermediate 1 and intermediate 2 undergo amidation reaction to generate intermediate 3 containing a sulfonamide group. Triethylamine is used as an acid binding agent to remove hydrogen chloride produced in the reaction and promote the forward reaction. The reaction process is shown below:

[0030]

[0031] S4. Under nitrogen protection, add intermediate 3, 3-chloro-1,2-propanediol and DMSO into a dry four-necked flask, stir to dissolve, then slowly add pyridine, raise the temperature to 80°C, stir and react for 3 hours, cool to room temperature after the reaction, and distill under reduced pressure to obtain an auxiliary agent; the dosage ratio of intermediate 3, 3-chloro-1,2-propanediol, pyridine and DMSO is 24g:5.3mL:7.3mL:200mL.

[0032] Under the action of triethylamine, the molar ratio of intermediate 3 and 3-chloro-1,2-propylene glycol is controlled to be 1:1 and 3-chloro-1,2-propylene glycol is slightly excessive, and the -NH- of intermediate 3 and the -Cl of 3-chloro-1,2-propylene glycol undergo nucleophilic substitution reaction. The reaction process is as follows:

[0033]

[0034] The additive contains carvacrol, which can effectively inhibit the growth and reproduction of a variety of pathogens, such as Gram-positive bacteria, Gram-negative bacteria and yeast, and has a strong bactericidal effect. Its bactericidal mechanism is mainly to destroy the cell wall and cell membrane of pathogens, thereby causing the death of pathogens. Sulfonamide structure is the pharmacophore of antibacterial compounds. Therefore, introducing sulfonamide group into the carvacrol structure can enhance the antibacterial activity of carvacrol, especially the activity against Staphylococcus aureus.

[0035] The additive also contains isothiazolinone structure, which has a strong inhibitory and killing effect on common bacteria, fungi, etc. Its mechanism of action is to kill bacteria by breaking the bonds of bacterial proteins. After contacting with bacteria, it can quickly and irreversibly inhibit their growth, thereby causing their death.

[0036] Therefore, the carvacrol containing the sulfonamide structure works together with the isothiazolinone structure to endow the adjuvant with excellent antibacterial activity.

[0037] The additive contains lipophilic heterocyclic rings and benzene rings, so the additive has good compatibility with other raw materials and can be evenly dispersed in polyester fibers to fully exert its antibacterial effect. In addition, the additive also contains multiple hydroxyl groups, which can modify the carboxyl groups on the surface of tourmaline to produce hydrogen bond interactions, so that the additive is further dispersed and can further exert its antibacterial effect, making polyester fibers less susceptible to bacterial contamination, and the quilt cover is less likely to produce odor, making it safer and more comfortable.

[0038] Furthermore, the antistatic agent is one or more of antistatic agent TD-5512, antistatic agent SK-212 and antistatic agent SN.

[0039] Furthermore, the antioxidant is one or more of antioxidant 1076, antioxidant 1010, antioxidant 1035, antioxidant 168, and antioxidant DLTP.

[0040] Furthermore, the light stabilizer is one or more of the ultraviolet absorber UV-327, ultraviolet absorber UV-0, ultraviolet absorber RMB, and light stabilizer GW-540.

[0041] The invention also discloses a breathable antibacterial multifunctional quilt, which is prepared according to the preparation process of the breathable antibacterial multifunctional quilt.

[0042] The beneficial effects of the present invention are as follows: hydrogen bond interactions exist between the additive and the modified tourmaline, and hydrogen bond interactions exist between the modified tourmaline and the additive, antioxidant, light stabilizer and other raw materials. Therefore, the raw materials in the polyester fiber of the present invention have good compatibility and can give full play to the synergistic effect, giving the quilt cover an excellent and stable antibacterial effect and a high-efficiency and long-lasting negative ion release function. In addition, due to the effects of the filler and the fixing cover, the quilt of the present invention can be both antibacterial and release negative ions, purifying the space environment while improving human health, and is breathable, safe and comfortable.
