Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a textile fabric for human and pet use and its preparation method. Background Technology

[0002] As living standards improve, more and more people are choosing to keep pets, and many pets share bedding and other items with their owners. However, the bacteria, microorganisms, and odors carried by pets can impact the shared living environment. For example, dogs and cats have a large number of potentially pathogenic bacteria in their intestines, including enteropathogenic Escherichia coli (O2). 157 (H7), Salmonella, Campylobacter, Klebsiella pneumoniae, etc. Ordinary textile fabrics cannot effectively inhibit the growth of these special types of bacteria, and the ammonia removal rate of the fabric (if the fabric can effectively remove ammonia) will decrease after washing, which in turn leads to the spread of disease and a decline in the quality of the living environment.

[0003] In related technologies, antibacterial and deodorizing textiles have functional limitations in scenarios where humans and pets share the same space. In particular, they have insufficient antibacterial spectrum coverage, poor washability, and short-lasting deodorizing performance, especially ammonia elimination performance, which makes it difficult to meet the health and safety requirements and long-term use needs of scenarios where humans and pets are in frequent contact.

[0004] In summary, there is an urgent need for a method to prepare a human-pet shared textile fabric that can resist bacteria, especially enteropathogenic Escherichia coli, Salmonella, Campylobacter, Klebsiella pneumoniae, and other special bacteria, and whose ammonia removal rate remains effective even after multiple washes. Summary of the Invention

[0005] This invention provides a human-pet shared textile fabric and its preparation method to solve the functional limitations of existing antibacterial and deodorizing textiles in human-pet shared scenarios, especially the insufficient antibacterial spectrum coverage, poor washability, and unsustainable deodorizing performance, particularly ammonia elimination performance, which makes it difficult to meet the health and safety requirements and long-term use needs of human-pet high-frequency contact scenarios.

[0006] This invention provides a method for preparing a human-pet compatible textile fabric, comprising the following steps: Yarn containing alkali-soluble polyester fibers is woven into a greige fabric, which is then subjected to alkali pore-forming treatment, antibacterial and deodorizing finishing, and heat setting to obtain the human-pet shared textile fabric. In the antibacterial and deodorizing finishing process, the antibacterial and deodorizing finishing liquid used includes an antibacterial and deodorizing agent, which includes marine algae extract and chitosan.

[0007] In one embodiment of the present invention, the alkaline solution pore-forming treatment includes: dissolving the fabric in alkaline solution at least twice, rolling after each dissolution, and steam treatment after the final rolling.

[0008] In one embodiment of the present invention, the concentration of the alkaline solution used in the initial alkaline solution dissolution is 80-100 g / L.

[0009] In one embodiment of the present invention, the temperature of the alkaline solution used during the initial alkaline solution dissolution is 30-40°C.

[0010] In one embodiment of the present invention, the concentration of the alkali solution used in the final alkali dissolution is 40-60 g / L.

[0011] In one embodiment of the present invention, the rolling slurry rate is 100%-110%.

[0012] In one embodiment of the present invention, the temperature of the steam treatment is 102-105°C, and the duration of the steam treatment is 45-60 min.

[0013] In one embodiment of the present invention, the antibacterial and deodorizing finishing process includes: impregnating the fabric with an antibacterial and deodorizing finishing solution.

[0014] In one embodiment of the present invention, the heat setting temperature is 130-140°C and the heat setting time is 2-4 seconds.

[0015] The present invention also provides a human-pet co-use textile fabric prepared according to the method described above.

[0016] The beneficial effects of this invention are: In this invention, by subjecting the fabric woven from yarn containing alkali-soluble polyester fibers to an alkaline solution porosimetry treatment, the alkali-soluble polyester fibers are utilized to dissolve in alkaline solutions, creating a loose porous structure within the yarn. This facilitates the penetration of antibacterial and deodorizing agents into the yarn during subsequent finishing processes, allowing them to bind to the yarn's internal pores and surface, thus imparting a long-lasting antibacterial and deodorizing effect to the fabric. Specifically, the marine algae extract and chitosan in the antibacterial and deodorizing agents effectively inhibit Escherichia coli (E. coli). 157 It contains H7), Salmonella, Campylobacter, Klebsiella pneumoniae, and three common bacteria. It also uses its acidity to absorb and neutralize gases such as ammonia produced on the pet's skin, thereby giving the fabric a long-lasting antibacterial effect against enteropathogenic Escherichia coli, Salmonella, Campylobacter, Klebsiella pneumoniae, and other special bacteria, as well as a deodorizing effect.

[0019] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0020] This invention provides a method for preparing a human-pet compatible textile fabric, comprising the following steps: Yarn containing alkali-soluble polyester fibers is woven into a greige fabric, which is then subjected to alkali pore-forming treatment, antibacterial and deodorizing finishing, and heat setting to obtain a human-pet textile fabric. In the antibacterial and deodorizing finishing process, the antibacterial and deodorizing finishing liquid used includes antibacterial and deodorizing agents, including marine algae extracts and chitosan.

[0021] In this invention, by subjecting the fabric woven from yarn containing alkali-soluble polyester fibers to an alkaline solution porosimetry treatment, the alkali-soluble polyester fibers are dissolved in alkaline solutions, creating a loose porous structure within the yarn. This facilitates the penetration of antibacterial and deodorizing agents into the yarn during subsequent finishing processes, allowing them to bind within the pores and onto the yarn surface, thus imparting a long-lasting antibacterial and deodorizing effect to the fabric. Specifically, the marine algae extract and chitosan in the antibacterial and deodorizing agents effectively inhibit Escherichia coli (E. coli). 157 It contains H7), Salmonella, Campylobacter, Klebsiella pneumoniae, and three common bacteria. It also uses its acidity to absorb and neutralize gases such as ammonia produced on the pet's skin, thereby giving the fabric a long-lasting antibacterial effect against enteropathogenic Escherichia coli, Salmonella, Campylobacter, Klebsiella pneumoniae, and other special bacteria, as well as a deodorizing effect.

[0022] In one embodiment of the present invention, the yarn further comprises a matrix fiber. The matrix fiber is selected from cotton fiber or hemp fiber or a combination thereof. The hemp fiber is selected from flax fiber or hemp fiber or a combination thereof. Exemplarily, based on the mass of the yarn, the mass of the alkali-soluble polyester fiber is 10wt%-30wt%, preferably 15wt%-30wt%.

[0023] In this invention, if the content of alkali-soluble polyester fiber is less than 10 wt%, fewer pores are formed, and the yarn cannot adsorb and bind enough antibacterial and deodorizing agents, resulting in poor antibacterial and deodorizing effects; if the content of alkali-soluble polyester fiber is higher than 30 wt%, the yarn has too many pores, the mechanical strength of the fabric is not high, and the service life of the fabric is affected.

[0024] In one embodiment of the present invention, after weaving and before alkaline solution pore forming treatment, the following steps are further included in sequence: singeing and desizing.

[0025] In one embodiment of the present invention, during the singeing process, the singeing method is as follows: singeing is performed once with four flames, two in the forward direction and two in the reverse direction, and the flame temperature is 700-900℃, preferably 750-900℃; the burning method is cutting burning (i.e., singeing along the tangent direction of the fabric plane), and the machine speed is 100-120m / min, preferably 110-115m / min.

[0026] In this invention, singeing can remove the fuzz from the fabric, preventing the fuzz from affecting the smooth progress of subsequent processes and improving the appearance of the finished product.

[0027] In one embodiment of the present invention, desizing includes: padding the fabric with an alkaline oxygen solution, followed by steaming at 100℃-102℃ for 45-60 minutes, then washing 2-3 times with hot water at 85-90℃, then washing 1-2 times with hot water at 75-80℃, and finally washing with warm water at 40-50℃. The alkaline oxygen solution includes: 10-15g / L NaOH, 8-10g / L hydrogen peroxide, 3-5g / L scouring agent, and 9-15g / L oxygen bleaching stabilizer. The padding method is: two dips and two nips, with a nip rate of 100%-110%.

[0028] In this invention, the desizing process can remove the sizing material added during the weaving process, which facilitates the smooth progress of subsequent processes.

[0029] In one embodiment of the present invention, after desizing and before alkaline pore-forming treatment, the process further includes: padding the treated fabric with an oxygen bleaching solution, then washing it 2-3 times with hot water at 85-90℃, then washing it 1-2 times with hot water at 75-80℃, then washing it with warm water at 40-50℃, then washing it with room temperature water, and finally drying it at a temperature of 150-180℃ and a machine speed of 20-40m / min. The oxygen bleaching solution includes: 3-5g / L hydrogen peroxide, 5-8g / L NaOH, 4-5g / L hydrogen peroxide stabilizer, 3-5g / L scouring agent, and 3-5g / L dispersant. The padding method is: two dips and two nips, with a nipping rate of 100%-110%.

[0030] In one embodiment of the present invention, the alkaline solution pore-forming treatment includes: dissolving the fabric in an alkaline solution at least twice, rolling it after each dissolution, and steam treatment after the final rolling. To fully dissolve the alkali-soluble polyester fibers and reduce adverse effects on the properties of the matrix fibers, the alkaline solution dissolution is preferably performed 2-3 times.

[0031] In this invention, by dissolving the greige fabric in an alkaline solution at least twice, the alkali-soluble polyester fibers in the yarn can be fully dissolved, thereby giving the fabric excellent antibacterial and deodorizing effects.

[0032] In one embodiment of the present invention, the alkali dissolution process includes: impregnating the fabric with an alkali solution, followed by rolling, sealing, and rolling for 20-30 hours, preferably 25-30 hours. During the rolling process, the alkali solution reacts fully with all parts of the fabric, thereby fully dissolving the alkali-soluble polyester fibers in the yarn.

[0033] To dissolve most of the alkali-soluble polyester fibers in the yarn, the initial alkali solution concentration is 80-100 g / L, and the temperature is 30-40°C, preferably 32-40°C; more preferably, the concentration is 85-100 g / L. The alkali solution is selected from sodium hydroxide solution, potassium hydroxide solution, or a combination of both. To dissolve the remaining alkali-soluble polyester fibers in the yarn, the final alkali solution concentration is 40-60 g / L, preferably 45-60 g / L.

[0034] In one embodiment of the present invention, the concentration of the alkali solution gradually decreases as the number of dissolution cycles increases. For example, the concentration difference of the alkali solution used in two adjacent dissolution cycles can be 20-60 g / L.

[0035] In one embodiment of the present invention, during the impregnation process, the liquid rolling rate is 100%-110%, preferably 105%-110%.

[0036] In one embodiment of the present invention, the temperature of the steam treatment is 102-105°C, preferably 103-104°C; the duration of the steam treatment is 45-60 min, preferably 50-60 min.

[0037] In one embodiment of the present invention, after alkaline pore-forming treatment and before bio-enzymatic polishing and washing, the following steps are further included in sequence: mercerizing treatment and dyeing. The mercerizing speed is 45-60 m / min, preferably 50-60 m / min, and the concentration of NaOH in the mercerizing solution is 190-230 g / L, preferably 200-230 g / L.

[0038] In one embodiment of the present invention, the bio-enzyme polishing and gentle washing process includes: polishing the fabric with a mist of water formed by a bio-enzyme solution, inactivating the bio-enzyme, and washing with water. The bio-enzyme is selected from cellulase. Exemplarily, the concentration of the bio-enzyme in the bio-enzyme solution is 10-30 g / L, preferably 15-30 g / L.

[0039] In one embodiment of the present invention, the temperature of the bio-enzyme polishing water wash is 45-55℃, preferably 48-55℃; the duration of the bio-enzyme polishing gentle wash is 30-50min, preferably 35-50min.

[0040] In this invention, a misted water stream formed by a bio-enzyme solution is used to polish the fabric. The atomized water stream evenly sprays the cellulase solution onto the fabric surface, allowing the cellulase to decompose the microfibers on the fiber surface. These microfibers are then removed through mechanical friction, reducing pilling and fuzzing during use. Furthermore, the enzymatic hydrolysis improves the fabric's luster and softness, creating a delicate texture and enhancing its appearance and comfort.

[0041] In one embodiment of the present invention, the inactivation treatment temperature is 75-85°C, preferably 78-85°C; the inactivation treatment duration is 10-20 min, preferably 12-20 min.

[0042] In one embodiment of the present invention, the antibacterial and deodorizing finishing process includes: impregnating the fabric with an antibacterial and deodorizing finishing solution.

[0043] In one embodiment of the present invention, the mass ratio of the antibacterial deodorizer to the grey fabric is 3-5:100, preferably 3.5-5:100. The solid content of the antibacterial deodorizer is 12%-18%, preferably 15%-18%. Exemplarily, the antibacterial deodorizer is selected from the bio-based antibacterial deodorizer FRESH-E7311 (the main components are marine algae extract and chitosan, with a solid content of 15%±3%). When using the bio-based antibacterial deodorizer FRESH-E7311, the pH of the system should be maintained within the range of 2.0-5.0.

[0044] In this invention, a pH adjuster can be used to adjust the pH of the system to the range of 2.0-5.0. For example, the pH adjuster is selected from at least one of citric acid, malic acid, acetic acid, and tartaric acid.

[0045] In one embodiment of the present invention, the antibacterial and deodorizing finishing liquid further includes a penetrant. The penetrant is selected from fatty alcohol polyoxyethylene ether or fatty alcohol phosphate or a combination thereof. Exemplarily, the mass ratio of penetrant to greige fabric is 1-5:100, preferably 5-6:100.

[0046] To enhance the softness and hand feel of the fabric, the antibacterial and deodorizing finishing solution also includes a softener. The softener is selected from hydrophilic softeners. Hydrophilic softeners include, but are not limited to, fatty amide derivatives, quaternary ammonium salts, and other substances. For example, the mass ratio of softener to greige fabric is 4-6:100, preferably 5-6:100.

[0047] In this invention, other functional additives, such as moisture-wicking agents and stain-resistant agents, can be added to the antibacterial and deodorizing finishing liquid as needed.

[0048] In one embodiment of the present invention, during the finishing process of the antibacterial and deodorizing agent, the liquid carry-over rate is 60%-100%, preferably 65%-100%. The vehicle speed is 20-30 m / min, preferably 22-30 m / min.

[0049] In one embodiment of the present invention, the heat setting temperature is 130-140°C, preferably 132-140°C; the heat setting time is 60-65 minutes, preferably 62-65 minutes.

[0050] In one embodiment of the present invention, after heat setting, the following steps are further included in sequence: pre-shrinking and air tapping.

[0051] In one embodiment of the present invention, during the pre-shrinking process, the pressure of the pre-shrinking component is 12-15 kg, preferably 13-15 kg. The pre-shrinking temperature is 100-120℃, preferably 105-120℃; the pre-shrinking speed is 25-60 m / min, preferably 30-60 m / min.

[0052] In one embodiment of the present invention, during the air beat-up process, the vehicle speed is 25-45 m / min, the duration of unidirectional wind is 3-5 s, and the temperature is 120-130℃, preferably 125-130℃.

[0053] In this invention, by air-beating the fabric, a three-dimensional spatial structure can be formed inside the fibers, eliminating internal stress and improving the feel of the fabric.

[0054] The present invention also provides a human-pet co-use textile fabric prepared according to the method described above.

[0055] It should be noted that the human-pet co-use textile fabric of the present invention should be washed with a neutral detergent during actual use.

[0056] In the following description, numerous details are set forth to provide a more thorough explanation of the embodiments of the present invention; however, it is apparent to one skilled in the art that the embodiments of the present invention may be practiced without these specific details.

[0057] Example 1 This embodiment provides a method for preparing a textile fabric suitable for both humans and pets, with the specific steps as follows: S1. Fabric preparation: Cotton fiber and alkali-soluble polyester fiber (commercially available) are blended at a mass percentage of 70wt%:30wt% to form a yarn with a count of 60S. The yarn was scanned by electron microscopy, and the results are as follows: Figure 1 As shown in A, by Figure 1 As can be seen, in this embodiment, the yarn has a porous structure inside; Using some yarn as warp yarn and the other yarn as weft yarn, the yarn is woven into a greige fabric with a surface density of 200 yarns / inch * 98 yarns / inch. S2. Preprocessing: The fabric is singed. The singeing process is a single singeing with four flames, two in the front and two in the back. The flame temperature is 700°C. The singeing method is cutting singeing (i.e., singeing along the tangent of the fabric plane). The machine speed is 120 m / min. The fabric was then immersed in an alkaline oxygen solution containing 10 g / L NaOH, 5 g / L KingfineCJ-031 scouring agent, and 8 g / L hydrogen peroxide, with a 100% immersion and rinsing rate. It was then steamed at 102°C for 45 minutes, followed by washing three times with 90°C hot water, then once with 80°C hot water, and finally once with 50°C warm water. The fabric was then immersed in an oxygen bleaching solution containing 5 g / L hydrogen peroxide, 8 g / L NaOH, 5 g / L hydrogen peroxide stabilizer ZJ-CH01, 3 g / L scouring agent KingfineCJ-031, and 3 g / L dispersant TY1-30, with a 100% immersion and rinsing rate. It was then washed three times with 90°C hot water, once with 80°C hot water, once with 50°C warm water, once with room temperature water, and finally dried at 180°C and 20 m / min. S3. Alkali solution pore-forming treatment: The fabric treated in step S2 is initially dissolved in an alkaline solution.

The dyed fabric was impregnated with an antibacterial and deodorizing finishing solution with a liquid content of 80% and a machine speed of 30 m / min. Calculations showed that the mass ratio of the bio-based antibacterial and deodorizing agent FRESH-E7311 to the fabric was 3.75wt%*80%:1=3:100, the mass ratio of the softener PERRSUTOL JJ03 to the fabric was 5wt%*80%:1=4:100, and the mass ratio of the penetrant TY-20A to the fabric was 6.25wt%*80%:1=5:100. S5. Heat setting: The fabric that has been treated with antibacterial and deodorizing agents is heat set at 135℃ for 65 minutes; S6.

After washing, the fabric is fed into a pre-shrinking machine and pre-shrinked at a temperature of 110℃ and a speed of 40m / min. During the pre-shrinking process, the pressure of the bearing rollers of the pre-shrinking machine is 13kg. Next, the pre-shrinked fabric is subjected to air beating. The maximum frequency of the fan is 50Hz, the frequency setting is 50%, the speed is 45m / min, the unidirectional airflow duration is 3s, and the temperature is 130℃, thus producing a human-pet compatible textile fabric.

Alkali solution pore-forming treatment: The fabric treated in step S2 is initially dissolved in an alkaline solution. Specifically, the fabric is placed in a sodium hydroxide solution with a concentration of 100 g / L, then rolled, sealed, and rolled for 20 hours, followed by rolling with a 100% liquid-pinching rate.

Next, rolling is performed, with a stripping rate of 110%. Then the fabric is steam-treated at 103℃ for 45 minutes; S4. The fabric is mercerized with a mercerizing solution containing 200g / L NaOH at a speed of 50m / min, followed by dyeing. An antibacterial and deodorizing finishing solution was prepared containing 6.67 wt% bio-based antibacterial and deodorizing agent FRESH-E7311 (commercially available, the main components of which are marine algae extract and chitosan, with a solid content of 15%), 8.33 wt% fabric softener PERRSUTOL JJ03 (a hydrophilic non-silicone fabric softener, commercially available) and 5 wt% penetrant TY-20A, and the pH was adjusted to 3.0 with citric acid. The dyed fabric was impregnated with an antibacterial and deodorizing finishing solution with a liquid load of 60% and a machine speed of 20m / min. Calculations showed that the mass ratio of the bio-based antibacterial and deodorizing agent FRESH-E7311 to the fabric was 6.67wt%*60%:1≈4:100, the mass ratio of the softener PERRSUTOL JJ03 to the fabric was 8.33wt%*60%:1≈5:100, and the mass ratio of the penetrant TY-20A to the fabric was 5wt%*60%:1=3:100. An antibacterial and deodorizing finishing solution was prepared containing 1.5 g / L of bio-based antibacterial and deodorizing agent FRESH-E7311 (commercially available, the main components of which are marine algae extract and chitosan, with a solid content of 15%), 3 g / L of fabric softener PERRSUTOL JJ03 (a hydrophilic non-silicone fabric softener, commercially available) and 2.5 g / L of penetrant TY-20A, and the pH was adjusted to 2.0 with citric acid. The dyed fabric was impregnated with an antibacterial and deodorizing finishing solution at a liquor ratio of 1:20 and a wash rate of 60%. S5. Heat setting: The fabric treated with antibacterial and deodorizing agents is heat set at 140℃ for 63 minutes; S6. Bio-enzyme polishing, pre-shrinking, and air tapping: A cellulase Power 11L solution with a concentration of 10 g / L was prepared, and the pH was adjusted to 5.5 using citric acid. The fabric was polished for 30-50 minutes using a mist of water at 55°C formed by cellulase solution, and the cellulase was inactivated at 75°C for 20 minutes. It was then washed with warm water at 45°C. After washing, the fabric is fed into a pre-shrinking machine and pre-shrinked at a temperature of 100℃ and a speed of 25m / min. During the pre-shrinking process, the pressure of the bearing rollers of the pre-shrinking machine is 12kg. Next, the pre-shrinked fabric is subjected to air beating. The maximum frequency of the fan is 50Hz, the frequency setting is 60%, the speed is 35m / min, the unidirectional airflow duration is 4s, and the temperature is 125℃, thus producing a human-pet compatible textile fabric.

[0060] Example 4 This embodiment provides a method for preparing a textile fabric suitable for both humans and pets, with the specific steps as follows: S1. Fabric preparation: Cotton fiber and alkali-soluble polyester fiber (commercially available) are blended at a mass percentage of 80wt%:20wt% to produce yarns with a count of 32S and yarns with a count of 16S. Using 32S yarn as warp and 16S yarn as weft, the yarn is woven into a greige fabric with a surface density of 133 threads / inch * 44 threads / inch. S2. Preprocessing: The fabric is singed. The singeing process is a single singeing with four flames, two in the front and two in the back. The flame temperature is 850℃. The singeing method is cut singeing (i.e., singeing along the tangent of the fabric plane). The machine speed is 115m / min. The fabric was then immersed in an alkaline oxygen solution containing 13 g / L NaOH and 4 g / L KingfineCJ-031, with two immersions and two rinsings, and the rinsing rate was 105%. It was then steamed at 101°C for 55 minutes, followed by washing with 87°C hot water three times, then washing with 78°C hot water once, and then washing with 48°C warm water once. The fabric was then immersed in an oxygen bleaching solution containing 5 g / L hydrogen peroxide, 7 g / L NaOH, 4.8 g / L hydrogen peroxide stabilizer ZJ-CH01, 4 g / L scouring agent KingfineCJ-031, and 4 g / L dispersant TY1-30, with a immersion and rinsing ratio of 108%. It was then washed twice with 87°C hot water, once with 78°C hot water, once with 48°C warm water, once with room temperature water, and finally dried at 180°C and 20 m / min. S3. Alkali solution pore-forming treatment: The fabric treated in step S2 is initially dissolved in an alkaline solution. Specifically, the fabric is placed in a sodium hydroxide solution with a concentration of 84 g / L, then rolled, sealed, and rolled for 25 hours, followed by rolling with a 100% liquid-pinching rate. The fabric is then dissolved again with a secondary alkaline solution. Specifically, the fabric is placed in a sodium hydroxide solution with a concentration of 48 g / L, then rolled, sealed, and rolled for 25 hours, followed by rolling with a 100% liquid-pinching rate. Then the fabric is steam-treated at 104℃ for 55 minutes; S4. The fabric is mercerized with a mercerizing solution containing 210 g / L NaOH at a speed of 55 m / min, followed by printing. An antibacterial and deodorizing finishing solution was prepared containing 6 wt% bio-based antibacterial and deodorizing agent FRESH-E7311 (commercially available, the main components of which are marine algae extract and chitosan, with a solid content of 15%), 8 wt% fabric softener PERRSUTOL JJ03 (a hydrophilic non-silicone fabric softener, commercially available) and 4 wt% penetrant TY-20A, and the pH was adjusted to 3.5 with citric acid. The printed fabric was impregnated with an antibacterial and deodorizing finishing solution with a liquid content of 70% and a machine speed of 25 m / min. Calculations showed that the mass ratio of the bio-based antibacterial and deodorizing agent FRESH-E7311 to the fabric was 6wt%*70%:1 = 4.2:100; the mass ratio of the softener PERRSUTOL JJ03 to the fabric was 8wt%*70%:1 = 5.6:100; and the mass ratio of the penetrant TY-20A to the fabric was 4wt%*70%:1 = 2.8:100. S5. Heat setting: The fabric that has been treated with antibacterial and deodorizing agents is heat set at 134℃ for 62 minutes; S6. Bio-enzyme polishing, pre-shrinking, and air tapping: A cellulase Power 11L solution with a concentration of 18 g / L was prepared, and the pH was adjusted to 4.8 using citric acid. The fabric was polished for 35 minutes using a mist of water at 52°C to form a cellulase solution, and the cellulase was inactivated at 78°C for 16 minutes. The fabric was then washed with warm water at 52°C. After washing, the fabric is fed into a pre-shrinking machine and pre-shrinked at a temperature of 115℃ and a speed of 35m / min. During the pre-shrinking process, the pressure of the pressure rollers of the pre-shrinking machine is 14kg. Next, the pre-shrinked fabric is subjected to air beating. The maximum frequency of the fan is 50Hz, set to 50%, the speed is 40m / min, the unidirectional airflow duration is 4s, and the temperature is 126℃, thus producing a human-pet compatible textile fabric.

[0061] Comparative Example 1 The difference between this comparative example and Example 1 is that no alkali-soluble polyester fibers were spun into the yarn, i.e., no alkali-soluble polyester fibers were spun into it.

[0062] Comparative Example 2 The difference between this comparative example and Example 1 is that the fabric was not treated with alkali solution to form holes.

[0063] Comparative Example 3 The difference between this comparative example and Example 1 is that the antibacterial deodorant HC-31212 is used instead of the bio-based antibacterial deodorant FRESH-E7311.

[0064] Comparative Example 4 The difference between this comparative example and Example 1 is that the antibacterial deodorant D9350 is used instead of the bio-based antibacterial deodorant FRESH-E7311.

[0065] Performance testing The testing agency was commissioned to test the removal rates (i.e., reduction rates of chemical component concentrations) of ammonia, acetic acid, isovaleric acid, and nonenal of the fabrics prepared in Examples 1-4 and Comparative Examples 1-4 before washing and after 10 washes, in accordance with GB / T 33610.1-2019 Determination of deodorizing properties of textiles - Part 1: General Rules and GB / T 33610.2-2017 Determination of deodorizing properties of textiles - Part 2: Detection tube method. Neutral detergent was used during the washing process. The results are shown in Table 1. The commissioned testing agency tested the fabrics prepared in Examples 1-4 and Comparative Examples 1-4 according to GB / T 20944.3-2008 Evaluation of Antimicrobial Properties of Textiles Part 3: Shaking Method. After washing 10 times, the fabrics tested were effective against Campylobacter (ATCC 29428) and Escherichia coli (O2). 157 The inhibition rates of H7 (ATCC 25922), Salmonella (ATCC 14028), Klebsiella pneumoniae (ATCC 4532) and Staphylococcus aureus (ATCC 6538) were measured, and the results are shown in Table 2.

[0066] Table 1 Odor Deodorization Performance Test Results

[0067] Table 2 Results of antibacterial effect test

[0068] As shown in Table 1, the removal rates of ammonia, acetic acid, isovaleric acid, and nonenal in the fabrics prepared in Examples 1-4 did not change significantly before and after washing. Furthermore, after 10 washes, the removal rates of Campylobacter (ATCC 29428) and Escherichia coli (O2) in the fabrics prepared in Examples 1-4 remained relatively stable. 157 The antibacterial rates against Bacillus subtilis (ATCC 25922), Salmonella (ATCC 14028), Klebsiella pneumoniae (ATCC 4532), and Staphylococcus aureus (ATCC 6538) were all greater than 80%. This result indicates that the fabric of the present invention has a long-lasting antibacterial and deodorizing effect.

[0069] As shown in Tables 1 and 2, compared with Comparative Example 1 (yarn does not contain alkali-soluble polyester fibers) and Comparative Example 2 (fabric is not treated with alkali), the fabric pair of Example 1 (yarn contains alkali-soluble polyester fibers, and the fabric is treated with alkali, and the treated fabric contains no alkali-soluble polyester fibers) showed significantly improved removal rates of ammonia, acetic acid, isovaleric acid, and nonenal, and also showed improved removal rates of Campylobacter (ATCC 29428) and Escherichia coli (O2). 157The antibacterial rates of *H7* (ATCC 25922), *Salmonella* (ATCC 14028), *Klebsiella pneumoniae* (ATCC 4532), and *Staphylococcus aureus* (ATCC 6538) were significantly improved. This result indicates that, in this invention, by subjecting the fabric woven from yarn containing alkali-soluble polyester fibers to alkali-solubilized treatment, the properties of alkali-soluble polyester fibers in alkali solutions can be utilized to create a loose porous structure within the yarn. This facilitates the penetration and adsorption of antibacterial and deodorizing agents into the yarn during subsequent finishing processes, allowing them to bind within the pores and onto the yarn surface, thereby imparting a long-lasting antibacterial and deodorizing effect to the fabric.

[0070] Table 1 shows that after 10 washes, the ammonia removal rates of the fabrics in Comparative Example 3 (using antibacterial deodorant HC-31212 instead of bio-based antibacterial deodorant FRESH-E7311) and Comparative Example 4 (using antibacterial deodorant D9350 instead of bio-based antibacterial deodorant FRESH-E7311) were significantly reduced, while the ammonia removal rate of the fabric in Example 1 (using bio-based antibacterial deodorant FRESH-E7311) showed no significant change. These results indicate that by using an antibacterial deodorant selected from bio-based antibacterial deodorant FRESH-E7311 (whose main components are marine algae extract and chitosan), marine algae extract and chitosan can effectively inhibit *Escherichia coli* (O. coli). 157 It contains H7), Salmonella, Campylobacter, Klebsiella pneumoniae, and three common bacteria. It also uses its acidity to absorb and neutralize gases such as ammonia produced on the pet's skin, thereby giving the fabric a long-lasting antibacterial effect against enteropathogenic Escherichia coli, Salmonella, Campylobacter, Klebsiella pneumoniae, and other special bacteria, as well as a deodorizing effect.
