Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textiles, in particular to a hair-adhesion-resistant fabric and a preparation method thereof. BACKGROUND

[0002] In recent years, with the continuous improvement of living standards and the growing emotional needs, raising pets has become a common lifestyle. However, while pets bring warmth and comfort, they also bring a series of problems, among which the cleaning and maintenance of bedding fabric are particularly prominent. In daily activities, pet hair is extremely easy to fall off and attach to sofas, clothes, especially bedding surfaces. Traditional bedding fabrics generally use cotton, hemp, chemical fibers and other materials. The fiber structure of such fabrics is loose, and the surface friction is large, so once the hair comes into contact, it is extremely easy to embed into the gap between the fibers, forming stubborn adhesion. Even if a vacuum cleaner, hair stick and other tools are used for cleaning, it is difficult to completely remove the hair, which not only consumes a lot of time and effort, but also may cause pilling and wear of the fabric due to repeated wiping, thereby shortening the service life of the bedding fabric. Moreover, pet sebaceous gland secretions and excrement residues and other substances can make the bedding fabric more prone to bacterial growth and odor generation.

[0003] Although some enterprises add antibacterial agents to give the bedding fabric certain antibacterial and odor-removing effects, there are still obvious shortcomings in solving the core problem of "hair adhesion". On the basis of pursuing antibacterial and hygienic bedding, users are increasingly demanding "non-hair-adhesion and easy-to-maintain" - they expect the bedding to effectively resist the adhesion of pet hair and to restore cleanliness through simple wiping, shaking or machine washing when a small amount of hair is attached, without complex cleaning processes.

[0004] In related technologies, some enterprises try to reduce hair adhesion by smoothing the surface of the fabric to give the fabric a hair-adhesion-resistant effect, but usually at the expense of the air permeability and comfort of the fabric, making it difficult to balance practicality and comfort. Therefore, from the aspect of raw material selection, the currently marketed hair-adhesion-resistant fabric generally selects long filament high-density woven fabric, such as polyester filament, viscose filament, Tencel filament, silk, nylon filament, cupro filament, and acetate filament. Long filament fabric has a cooling feeling and needs to meet the following two conditions: the long filament has no excess fiber head end protruding, i.e. a large contact area, and the thermal conductivity of nylon is relatively large, and the public standard moisture regain of viscose filament, Tencel filament, silk, cupro filament and acetate filament fabric is high. These long filament fabrics have a distinct cooling feeling during use, which is not suitable for use in autumn and winter. Only polyester filament fabric does not have a cooling feeling, but polyester filament fabric is prone to static electricity and has adsorption properties for pet hair, so it does not have a pet hair-adhesion-resistant effect. SUMMARY

[0005] The present application provides a kind of anti-sticky hair fabric and its preparation method, so that the fabric meets the use demand of anti-sticky hair and comfort in autumn and winter season.

[0006] The present application provides a kind of preparation method of anti-sticky hair fabric, comprising the following steps: S1. With fiber filament as warp, Lyocell fiber-cotton fiber blended yarn as weft, weaving is carried out to obtain gray cloth, the fiber filament is selected from acetate fiber filament or microporous structure containing polyester fiber filament or combination thereof, the standard moisture regain of the polyester fiber filament is greater than or equal to 4.2%; S2. The gray cloth is sequentially subjected to reverse side singeing, oil removal and cellulase polishing soft washing to obtain the anti-sticky hair fabric.

[0007] In an embodiment of the present application, in step S1, the mass of cotton fiber accounts for 20%-50% of the mass of the Lyocell fiber-cotton fiber blended yarn, preferably 30%-50%.

[0008] In an embodiment of the present application, in step S2, during the reverse side singeing process, the singeing method is: singeing is carried out once, four fire holes, reverse side singeing, the flame temperature is 700-900℃, the cloth singeing method is cutting, the speed is 100-120m / min, preferably 105-110m / min.

[0009] In an embodiment of the present application, in step S2, the cellulase polishing soft washing comprises: using an atomized treatment liquid containing cellulase to polish the gray cloth, and inactivating the cellulase, and in the polishing process, the gray cloth is mechanically beaten in a wet state.

[0010] In an embodiment of the present application, in step S2, after the oil removal and before the cellulase polishing soft washing, the following steps are further included: the gray cloth is placed in a refining solution containing sodium hydroxide for refining treatment, then hydrogen peroxide is used for oxygen bleaching treatment, and heat treatment is carried out.

[0011] In an embodiment of the present application, in step S2, after the oil removal and before the cellulase polishing soft washing, the following steps are further included: the gray cloth is impregnated with a dispersing dye-containing padding for hot melt dyeing.

[0012] In an embodiment of the present application, in step S2, the temperature of the hot melt dyeing treatment is 200-220℃, and the time of the hot melt dyeing treatment is 30-90s.

[0013] In an embodiment of the present application, in step S2, after the cellulase polishing soft washing, the following steps are further included: the gray cloth is immersed in a finishing solution containing an antibacterial and deodorizing agent, is pressed and dried.

[0014] In an embodiment of the present application, after the cellulase polishing soft washing in step S2, the grey cloth is further subjected to pre-shrinking treatment.

[0015] The present application also provides a lint-resistant fabric prepared according to the method as described above.

[0016] The present application has the following advantages: In the present application, the acetate fiber filaments, the polyester fiber filaments containing micro-porous structures, and the lyocell fibers have smoothness, which can prevent pet hair from being embedded into the gaps inside the fabric, and can play an anti-static effect through the low surface resistance characteristics of the acetate fiber filaments, the micro-porous structures of the polyester fiber filaments, or the hydrophilic groups of the lyocell fibers, thereby preventing the adhesion of hair; the lyocell fibers, cotton fibers, and other short fibers can impart comfort to the fabric. However, the hairiness contained in the yarn formed by the lyocell fibers, cotton fibers, and other short fibers is prone to adhere to hair during use. The reverse singeing treatment can remove the fluff on the surface of the grey cloth, and the oil removal treatment can remove the pollutants such as oil and wax attached to the grey cloth, thereby facilitating the smooth progress of subsequent processes. During the cellulase polishing soft washing process, the cellulase can fully remove the hairiness on the surface of the fabric through enzymatic hydrolysis and mechanical soft washing, and the polishing treatment can improve the smoothness of the surface of the grey cloth, thereby improving the lint-resistant effect of the fabric. In other words, the present application imparts the lint-resistant effect and comfort to the fabric by selecting the yarn formed by specific fibers and combining the reverse singeing, oil removal, and cellulase polishing soft washing processes, so as to meet the use requirements in autumn and winter. DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0018] An embodiment of the present application provides a preparation method of a lint-resistant fabric, which comprises the following steps: S1. Weaving is performed by taking fiber filaments as warp yarns and taking lyocell fiber-cotton fiber blended yarns as weft yarns to obtain a grey cloth, wherein the fiber filaments are selected from acetate fiber filaments or polyester fiber filaments containing micro-porous structures or a combination of both, and the polyester fiber filaments have a standard moisture regain greater than or equal to 4.2%; S2. The grey cloth is sequentially subjected to reverse singeing, oil removal, and cellulase polishing soft washing to obtain a lint-resistant fabric.

[0019] In the present application, the acetate fiber filament, the polyester fiber filament with a microporous structure and the lyocell fiber have smoothness, which can prevent pet hair from being embedded into the gap inside the fabric, and can play an antistatic effect through the low surface resistance characteristic of the acetate fiber filament, the microporous structure of the polyester fiber filament or the hydrophilic group of the lyocell fiber, thereby preventing the adhesion of hair; the short fibers such as lyocell fibers and cotton fibers can endow the fabric with comfort, however, the hair contained in the yarn formed by the short fibers such as lyocell fibers and cotton fibers is prone to adhere to hair during use, the reverse singeing treatment can remove the fluff on the surface of the gray fabric, the degreasing treatment can remove the pollutants such as oil and wax attached to the gray fabric, thereby facilitating the smooth progress of subsequent processes, and in the cellulase polishing and soft washing process, the cellulase can fully remove the hair on the surface of the gray fabric through enzymatic hydrolysis and mechanical soft washing, and the polishing treatment can improve the smoothness of the surface of the gray fabric, thereby improving the anti-hair adhesion effect of the fabric. In other words, the present application endows the fabric with the anti-hair adhesion effect and comfort by selecting the yarn formed by specific fibers and combining the reverse singeing, degreasing and cellulase polishing and soft washing processes, so as to meet the use requirements in autumn and winter.

[0020] In order to avoid scratches on the lyocell fiber in the subsequent dyeing process, in the present application, the lyocell fiber is selected from acid-resistant lyocell fibers, such as A100, G100 and the like.

[0021] In order to avoid the blockage of the microporous structure of the polyester fiber filament by sizing agent during the sizing process, a sizing-free weaving process is adopted, and oil agent is not suitable for use in the weaving process.

[0022] In an embodiment of the present application, in step S1, based on the quality of the lyocell fiber-cotton fiber blended yarn, the mass fraction of cotton fiber is 20wt%-50wt%, preferably 25wt%-50wt%.

[0023] In order to make the fabric have good hand feeling while avoiding the reverse fluff from penetrating into the front of the fabric and hooking pet hair in subsequent use, in step S2, only the reverse of the gray fabric is subjected to reverse singeing treatment. In order to avoid the influence of high temperature on the polyester fiber filament in the gray fabric, the reverse singeing is carried out by cutting singeing. In the reverse singeing process, one-time singeing is adopted, four flame ports are used, the reverse singeing is carried out, the flame temperature is 700-900℃, preferably 750-900℃; the singeing method is cutting singeing (i.e. the flame port is along the tangent direction of the plane of the fabric), the speed is 100-120m / min, preferably 105-110m / min.

[0024] In an embodiment of the present application, after the oil removal in step S2, before the cellulase polishing soft washing, the following steps are further included: placing the gray cloth in a refining solution containing sodium hydroxide for refining treatment, then using hydrogen peroxide for oxygen bleaching treatment, and then performing heat treatment. In the refining solution, the concentration of sodium hydroxide is 1-2 g / L, preferably 1.5-2 g / L. The refining solution also contains an emulsified oil removal agent, and the concentration of the emulsified oil removal agent is 0.5-2 g / L, preferably 1-2 g / L; for example, the emulsified oil removal agent can be a fatty alcohol polyoxyethylene ether (such as AEO-3, AEO-7, AEO-9, etc.), an alkyl glycoside, a fatty acid methyl ester ethoxylate, an emulsified oil removal agent WD-071B, etc. The temperature of the refining treatment is 80-90°C, preferably 85-90°C; the time length of the refining treatment is 20-30 min, preferably 25-30 min. During the refining treatment, the bath ratio is 1:10-15, preferably 1:12-15. The concentration of the hydrogen peroxide is 3-5 g / L, preferably 4-5 g / L; the pH of the hydrogen peroxide is 10-11, preferably 10.5-11. The temperature of the oxygen bleaching treatment is 90-100°C, preferably 95-100°C, and the time length of the oxygen bleaching treatment is 25-30 min, preferably 27-30 min. The temperature of the heat treatment is 160-180°C, preferably 165-180°C; the time length of the heat treatment is 30-60 s, preferably 40-60 s.

[0025] In an embodiment of the present application, in step S2, the cellulase polishing soft washing includes: using an atomized treatment solution containing cellulase to polish the gray cloth, and inactivating the cellulase, and in the polishing process, mechanically beating the fabric in a wet state. In the atomized treatment solution, the concentration of the cellulase is 10-30 g / L, preferably 15-30 g / L; the temperature of the atomized treatment solution is 50-55°C, preferably 52-55°C; the pH of the atomized treatment solution is 4.5-5.5, preferably 4.8-5.5, and substances such as acetic acid, citric acid, etc. can be used to adjust the pH of the atomized treatment solution. The inactivation treatment includes: inactivating the cellulase by heating the atomized treatment solution to 80-85°C and maintaining the temperature for 10-20 min.

[0026] In the present application, the cellulase polishing soft washing treatment of the gray cloth can uniformly spray the solution containing cellulase to the surface of the gray cloth through the atomized treatment solution, decompose the micro fibers on the surface of the fiber through the cellulase, improve the smoothness of the surface of the fabric, and further play the effect of preventing the fabric from sticking to the hair; the contact effect between the atomized treatment solution and the fabric can be improved through mechanical beating, thereby further removing the hair on the surface of the gray cloth, and the bulkiness and softness of the gray cloth can be improved through mechanical beating.

[0027] In an embodiment of the present application, after the oil removal and before the cellulase polishing and soft washing in step S2, the following step is further included: the semi-finished product is padded with a dyeing solution containing a disperse dye, and hot melt dyeing is performed. The amount of the dye needs to be determined according to the color, and the dyeing solution further contains a leveling agent and a dispersant. The amount of the leveling agent is 0.5-1.0 g / L, and preferably 0.6-1.0 g / L. The concentration of the dispersant is 0.5-1.0 g / L, and preferably 0.6-1.0 g / L. The dispersant can be NNO (sodium salt of naphthalene sulfonate formaldehyde condensate (sodium methylene bisnaphthalene sulfonate)), dispersant MF (methyl naphthalene sulfonate formaldehyde condensate), dispersant CNF (benzyl naphthalene sulfonate formaldehyde condensate), lignin sulfonate, polypropylene salt, phosphate, and the like. Acetic acid is used to adjust the pH of the dyeing solution to 4.5-6, and preferably 5.0-6.0. The temperature of the hot melt dyeing treatment is 200-220°C, and preferably 210-220°C. The time of the hot melt dyeing treatment is 30-90 s, and preferably 40-90 s.

[0028] In the related art, the polyester fiber is usually dyed by using the high-temperature and high-pressure technology of the machine cylinder. However, the use of this method for treatment is prone to hairiness in the dyeing process. The present application creatively proposes that the polyester fiber filament (or acetate fiber filament) is dyed by using the atmospheric pressure and high-temperature hot melt dyeing technology, which can avoid the problem that the hairiness generated in the dyeing process by using the high-temperature and high-pressure dyeing technology adheres to the hair in the use process, and further plays a hair-adhesion-preventing effect.

[0029] In order to give the fabric antibacterial and deodorizing effects, after the oil removal and before the cellulase polishing and soft washing in step S2, the following step is further included: the treated fabric is padded with a finishing liquid containing an antibacterial and deodorizing agent, and is dried. The mass ratio of the antibacterial and deodorizing agent to the fabric weight is 3-5:100, and preferably 4:100. The solid content of the antibacterial and deodorizing agent is 15%±3%. Exemplarily, the antibacterial and deodorizing agent is selected from the biological-based antibacterial and deodorizing agent FRESH-E7311 (main components are marine algal extract and chitosan, and the solid content is 15%±3%). The use environment of FRESH-E7311 should maintain a pH of 2.0-5.0. Citric acid, malic acid, acetic acid, tartaric acid, and the like can be used to adjust the pH to 2.0-5.0. The liquid retention rate is 60%-100%, and preferably 65%-100%. The speed is 20-30 m / min, and preferably 22-30 m / min.

[0030] In the present application, the antibacterial and deodorizing agent can penetrate into the inside of the gray fabric through the microporous structure of the polyester fiber filament, and is adsorbed in the pores and on the surface of the yarn. The marine algal extract and chitosan in the biological-based antibacterial and deodorizing agent FRESH-E7311 can effectively inhibit the growth of Escherichia coli (O 157: H7), Salmonella, Campylobacter, Klebsiella pneumoniae and three common bacteria, and utilize the acid to adsorb and neutralize the ammonia gas and other gases generated on the surface of the pet, thereby imparting the fabric with a persistent antibacterial effect and deodorizing effect against special bacterial species such as enteropathogenic Escherichia coli, Salmonella, Campylobacter, Klebsiella pneumoniae, and the like. Furthermore, the marine algal extract and chitosan can be adsorbed onto the surface of the fabric by adsorption (if the fiber filaments are selected from acetate fiber filaments, the marine algal extract and chitosan can also be adsorbed and combined due to the heterogeneous cross-section of the acetate fiber filaments), thereby imparting the fabric with antibacterial and deodorizing effects.

[0031] In order to promote the penetration of more antibacterial and deodorizing agents into the yarn and improve the antibacterial and deodorizing effects, the finishing liquid also includes a penetrating agent. The penetrating agent is selected from fatty alcohol polyoxyethylene ether or fatty alcohol phosphate or a combination of the two. Exemplarily, the mass ratio of the penetrating agent to the gray fabric is 2-5:100, preferably 3-5:100.

[0032] In order to dye the cotton fibers and lyocell fibers, after the cellulase polishing soft washing in step S2 and before the fabric is impregnated with the antibacterial and deodorizing agent finishing liquid, the following steps are further included: impregnating the fabric with a dyeing liquid containing reactive dyes, adjusting the pH to 5.5-6.5, increasing the temperature to 55-65°C, adding a dyeing promoter and a fixing agent, soaping, and washing. Acetic acid, citric acid, or the like can be used to adjust the pH to 5.5-6.5. The rate of temperature increase is 1.0-1.5°C / min, preferably 1.2-1.5°C / min. The final concentration of the dyeing promoter is 5-20 g / L, preferably 8-20 g / L; the dyeing promoter is selected from sodium sulfate (i.e., sodium sulfate), sodium chloride, or the like. The fixing agent is selected from polyamine substances (such as fixing agent LA), epoxy chloropropane derivatives, silicone-modified resins, water-based polyurethane, or the like. A weakly basic baking soda is selected as the fixing agent. The final concentration of the fixing agent is 20-25 g / L, preferably 21-25 g / L. The soaping temperature is 85-95°C, preferably 88-92°C; the soaping time is 8-12 min, preferably 9-12 min. The washing temperature is 55-65°C, preferably 58-65°C; the washing time is 8-12 min, preferably 9-12 min.

[0033] In order to improve the hand feeling of the fabric, after the cotton fibers and lyocell fibers are dyed and before the fabric is impregnated with the antibacterial and deodorizing agent finishing liquid, the following steps are further included: impregnating the fabric with a liquid containing a softening agent, and secondary drying. In the liquid, the concentration of the softening agent is 5-30 g / L, preferably 10-30 g / L; the softening agent is selected from a silicon-free hydrophilic softening agent, exemplarily, the softening agent is selected from PERRUSTOL JJ03. The temperature of the liquid is 20-30°C, preferably 25-30°C. The liquid retention rate is 60%-80%, preferably 70%-80%. The temperature of the secondary drying is 160-180°C, preferably 165-180°C.

[0034] In order to eliminate the internal stress of the fabric and keep the size stability of the fabric, after the cellulase polishing soft washing in step S2, the following step is further included: pre-shrinking the fabric. In the pre-shrinking process, the pre-shrinking process adopted has a pressure of 12-15 kg, preferably 13-15 kg. The pre-shrinking temperature is 100-120°C, preferably 110-120°C; and the pre-shrinking speed is 25-60 m / min, preferably 30-60 m / min.

[0035] Another embodiment of the present application further provides a non-sticky hair fabric prepared according to the method as described above.

[0041] Comparative Example 1 The difference between this comparative example and Example 4 is that the ordinary DTY 75D / 72F lusterless polyester fiber filament (commercially available, the standard moisture regain is 0.4%) without a microporous structure is used to replace the DTY 75D / 72F lusterless polyester fiber filament (commercially available, the standard moisture regain is 4.2%) containing a microporous structure.

[0042] Comparative Example 2 The difference between this comparative example and Example 4 is that the fabric is directly subjected to oil removal treatment without back-side singeing treatment.

[0043] Comparative Example 3 The difference between this comparative example and Example 4 is that the fabric treated in step S5 is directly subjected to step S7 without step S6 (i.e., without cellulase polishing and soft washing treatment).

[0044] Comparative Example 4 The difference between this comparative example and Example 4 is that the fabric treated in Step S4 is directly treated in Step S6 without Step S5 (i.e. without treatment with the antibacterial deodorant-containing finishing liquid).

[0045] Performance test The static voltage half-life and induced static voltage (i.e. static voltage) of the fabric prepared in Examples 1-4 and Comparative Examples 1-4 were tested according to GB / T 12703.1-2008 Textiles - Evaluation of the electrostatic properties - Part 1: Static voltage half-life, and the results are shown in Table 2, wherein the requirements for non-sticky hair are shown in Table 1; The anti-hair-sticking performance of the fabric prepared in Examples 1-4 and Comparative Examples 1-4 was tested according to T / HOMETEX 45-2024 Anti-pet-hair fabric for home textiles, wherein the hair sample was natural cat hair, and the initial amount of hair was 50. When the sample surface was cleaned before counting the number of hairs stuck, the hairs were shaken 5 times at the end of the test, and the results are shown in Table 2.

[0046] Table 1 Requirements for non-sticky hair

[0047] Table 2 Anti-hair-sticking performance test results

[0048] Table 3 Bacteriostatic deodorant performance test results after 10 washes

[0049] As shown in Table 2, compared with Comparative Example 1 (using common DTY 75D / 72F dull polyester fiber filaments without micro-porous structure instead of DTY 75D / 72F dull polyester fiber filaments with micro-porous structure), Comparative Example 2 (without back singeing treatment) and Comparative Example 3 (without cellulase polishing soft washing treatment), the static voltage half-life, induced static voltage and hair sticking number of Example 4 (using DTY 75D / 72F dull polyester fiber filaments with micro-porous structure, with back singeing treatment and cellulase polishing soft washing treatment) are significantly reduced. The results show that, in the present application, the acetate fiber filaments, polyester fiber filaments with micro-porous structure and lyocell fibers have smoothness, which can prevent pet hair from embedding into the gap inside the fabric, and can play an antistatic effect through the low surface resistance characteristics of acetate fiber filaments, the micro-porous structure of polyester fiber filaments or the hydrophilic groups of lyocell fibers to prevent hair adhesion; short fibers such as lyocell fibers and cotton fibers can give the fabric comfort, however, the hair contained in the yarn formed by short fibers such as lyocell fibers and cotton fibers is prone to adhere to hair during use, back singeing treatment can remove the fluff on the surface of the gray fabric, oil removal treatment can remove pollutants such as oil and wax attached to the gray fabric, facilitating the smooth progress of subsequent processes, during the cellulase polishing soft washing process, cellulase can fully remove the hair on the surface of the fabric through enzymatic and mechanical soft washing effects, and polishing treatment can improve the smoothness of the surface of the gray fabric, thereby improving the anti-hair sticking effect of the fabric. In other words, the present application gives the fabric anti-hair sticking effect and comfort by selecting yarn formed by specific fibers and combining back singeing, oil removal and cellulase polishing soft washing processes, to meet the use requirements in autumn and winter seasons.

[0050] As shown in Table 3, compared with Comparative Example 4 (without treatment of finishing liquid containing antibacterial and deodorizing agent), the ammonia removal rate and bacteriostatic rate of Example 4 (treated with finishing liquid containing antibacterial and deodorizing agent) are significantly improved. The results show that, in the present application, the antibacterial and deodorizing agent can penetrate into the inside of the gray fabric through the micro-porous structure of the polyester fiber filaments, and be adsorbed in the pores and on the surface of the yarn, the marine algae extract and chitosan in the bio-based antibacterial and deodorizing agent FRESH-E7311 can effectively inhibit E. coli (O 157 : H7), Salmonella, Campylobacter, Klebsiella pneumoniae and three common bacteria, and can adsorb and neutralize the ammonia gas and other gases generated on the surface of pets by using its acidity, thereby giving the fabric a persistent antibacterial effect against enteropathogenic E. coli, Salmonella, Campylobacter, Klebsiella pneumoniae and other special bacteria species and a deodorizing effect. Moreover, the marine algae extract and chitosan can be adsorbed on the surface of the gray fabric (if the fiber filaments are selected from acetate fiber filaments, because the acetate fiber filaments are of a special cross-section, the marine algae extract and chitosan can also be adsorbed and combined), giving the fabric an antibacterial effect and a deodorizing effect.
