Description

Technical Field

[0001] The utility model belongs to the technical field of protective fabrics, and in particular relates to a protective isolation fabric. Background Art

[0002] Fabric is the most superficial material of clothing. Clothing fabric is the most basic material basis in clothing design. Any clothing is processed through the selection, cutting, production and other processes of fabric to achieve the purpose of wearing and display. With the improvement of people's living standards, the quality of modern clothing fabrics is getting higher and higher. Existing clothing fabrics have relatively low strength and poor wear resistance. The sweat absorption and air permeability of clothing fabrics are relatively poor. The weight per unit area is large, and a lot of waste is generated after being discarded, which is not conducive to subsequent treatment and the trend of low-carbon environmental protection. After being worn for a long time, if the gas is not discharged in time, the clothing made of it is easy to emit sour and smelly gas, which is not only not very convenient to use, but also causes physical diseases to the wearer.

[0003] In order to solve the above problems existing in existing fabrics, such as an antibacterial polypropylene plant fiber non-woven fabric, chemical long fibers and plant short fibers are combed and reinforced through a spunlace process to maintain the unique properties of the fibers. Plant fibers are naturally hygroscopic and breathable, and liquid absorption and penetration are fast. Polypropylene spunbond fabric has a good moisture barrier effect, which keeps the non-woven fabric dry and crisp, and the non-woven fabric has good strength and does not deform. At the same time, polypeptide antibacterial agents and bamboo fibers and flax fibers have excellent antibacterial effects, forming a multi-layer antibacterial and antibacterial effect to prevent the growth of a variety of pathogens and harmful bacteria. However, this structure still has the following shortcomings:

[0004] 1. Although the structure is reinforced by spunlace process using chemical long fibers and plant short fibers, the chemical long fibers have the disadvantages of poor hygroscopicity, poor heat resistance and poor air permeability, and the plant short fibers contain crystalline fibers, which are prone to softening when exposed to high temperature environments, thus affecting the wearer's use.

[0005] 2. Although this structure has a certain antibacterial effect through polypeptide antibacterial agents and bamboo fibers and flax fibers, the production cost is relatively high because most of the current preparation methods of peptide antibacterial agents require complex processes and equipment, and require a large amount of raw materials and time. In addition, bamboo fibers and flax fibers are prone to wrinkles when used for a long time.

[0006] 3. The structure uses the spunlace process to fix the chemical long fibers and the fabric short fibers. The relative structure is relatively loose. In order to achieve the wearing performance, the thickness of the finished fabric needs to be increased. The final unit weight of the fabric is 60g / m 2 The above results in an increase in solid waste generated after the garments are discarded, which is not conducive to subsequent environmental protection treatment. Utility Model Content

[0007] In view of this, the embodiment of the utility model is committed to providing a protective isolation fabric, which solves the problems of poor heat resistance, poor air permeability and heavy weight per unit area of ​​the existing fabrics by adopting a tight interlayer structure of a microporous membrane layer, a polypropylene spunbond fabric layer and a fabric outer layer in the protective isolation fabric.

[0008] The utility model provides a protective isolation fabric, which comprises a fabric body and a fabric outer layer. The fabric body comprises a microporous membrane layer and a polypropylene spunbond fabric layer which are stacked. The fabric outer layer is located outside the polypropylene spunbond fabric layer.

[0009] In the above scheme, the protective isolation fabric can enhance the heat resistance and air permeability of the fabric body by using a microporous membrane layer, thereby improving the comfort of the wearer. At the same time, the protective isolation fabric adopts a polypropylene spunbond fabric layer, so that the fabric body has a good antibacterial effect and low cost. The protective isolation fabric adopts a compact interlayer structure, which can reduce the weight of the fabric per unit area while meeting the wearing performance, thereby reducing the volume of the final solid waste and being more conducive to subsequent environmental protection treatment.

[0010] In a specific embodiment of the utility model, the microporous membrane layer includes a first microporous membrane layer, a second microporous membrane layer and a third microporous membrane layer which are stacked in sequence. The microporous channel at the connection between the first microporous membrane layer and the second microporous membrane layer is bent at a first preset angle, the microporous channel at the connection between the second microporous membrane layer and the third microporous membrane layer is bent at a second preset angle, and the microporous channels between the first microporous membrane layer, the second microporous membrane layer and the third microporous membrane layer are staggered.

[0011] In a specific implementation of the present invention, the first microporous membrane layer, the second microporous membrane layer and the third microporous membrane layer are all composed of ultra-high molecular polyethylene membrane layers and dimethylformamide layers, and the ultra-high molecular polyethylene membrane layers and the dimethylformamide layers are arranged alternately with each other.

[0012] In a specific implementation of the present invention, the first preset angle and the second preset angle are 90 degrees.

[0013] In a specific implementation of the present invention, the outer side walls of the first microporous membrane layer, the second microporous membrane layer and the third microporous membrane layer are all provided with a plurality of film holes, which are parallel to each other and arranged at equal intervals.

[0014] In a specific implementation of the present invention, the pore size of the film pores is less than 100 nm.

[0015] In a specific implementation of the present invention, the polypropylene spunbond fabric layer includes a first antibacterial fiber layer and a second antibacterial fiber layer. The first antibacterial fiber layer and the second antibacterial fiber layer are alternately arranged to form a grid structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] At least one embodiment of the present invention provides a protective isolation fabric, such as Figure 1 As shown, the protective isolation fabric includes a fabric body 1 and a fabric outer layer 4. The fabric body 1 includes a microporous membrane layer 2 and a polypropylene spunbond fabric layer 3 which are stacked. The fabric outer layer 4 is located on the outside of the polypropylene spunbond fabric layer 3. In this way, the protective isolation fabric can enhance the heat resistance and air permeability of the fabric body 1 and improve the comfort of the wearer by adopting the microporous membrane layer 2. At the same time, the protective isolation fabric adopts the polypropylene spunbond fabric layer 3, so that the fabric body 1 has a good antibacterial effect and low cost. In the embodiment of the utility model, the protective isolation fabric adopts a tight interlayer structure. While meeting the wearing performance, it can reduce the weight of the fabric per unit area, achieve the reduction of the final solid waste, and is more conducive to subsequent environmental protection treatment. It also makes the protective isolation fabric have high strength and lightweight performance.

[0023] For example, the microporous membrane layer 2 is located at the bottom end of the fabric body 1, the polypropylene spunbond fabric layer 3 is located at the top end of the fabric body 1 and is bonded to the upper end of the microporous membrane layer 2, and the outer side of the polypropylene spunbond fabric layer 3 is bonded to the fabric outer layer 4.

[0024] In a specific embodiment of the present invention, Figure 2 As shown, the microporous membrane layer 2 includes a first microporous membrane layer 21, a second microporous membrane layer 22, and a third microporous membrane layer 23 which are stacked in sequence. The microporous channel m at the connection between the first microporous membrane layer 21 and the second microporous membrane layer 22 is bent at a first preset angle, the microporous channel m at the connection between the second microporous membrane layer 22 and the third microporous membrane layer 23 is bent at a second preset angle, and the microporous channels m between the first microporous membrane layer 21, the second microporous membrane layer 22, and the third microporous membrane layer 23 are staggered. In this way, by setting the first microporous membrane layer 21, the second microporous membrane layer 22, and the third microporous membrane layer 23 to be bent and staggered relative to each other, the strength of the fabric body can be enhanced, and the fabric body has the characteristics of strong hygroscopicity, good heat resistance, and not easy to soften.

[0025] For example, the first microporous membrane layer 21 is located at the bottom of the fabric body 1 , the upper end of the first microporous membrane layer 21 is bonded to the second microporous membrane layer 22 , and the upper end of the second microporous membrane layer 22 is bonded to the third microporous membrane layer 23 .

[0026] For example, through the combination of multiple layers of microporous membranes, the fabric structure is more compact. According to the performance indicators in GB 24539-2021 "Protective Clothing. Chemical Protective Clothing", the results are as follows:

[0027] Tearing strength: longitudinal 17N, transverse 11N;

[0028] Resistance to bending damage: 501 revolutions, no cracking;

[0029] Breaking strength: longitudinal 130N, transverse 62N;

[0030] Puncture resistance: average value is 6N;

[0031] High temperature resistance: longitudinal +15.3, transverse -9.7;

[0032] Wear resistance: >1000 times.

[0033] The fabric weight per unit area is about 35g / m 2 , compared with the existing mainstream products 60g / m 2 A weight reduction of over 40% can effectively reduce the amount of solid waste generated by the final discarded protective clothing, which is conducive to waste minimization.

[0034] The first preset angle and the second preset angle can be arranged so that the first microporous membrane layer 21, the second microporous membrane layer 22 and the third microporous membrane layer 23 are bent relative to each other. On this basis, the embodiment of the utility model does not limit the specific values ​​of the first preset angle and the second preset angle. For example, in some embodiments, the first preset angle and the second preset angle are 90 degrees.

[0035] In at least one embodiment of the present invention, Figure 3 As shown, the first microporous membrane layer 21, the second microporous membrane layer 22 and the third microporous membrane layer 23 are all composed of ultra-high molecular polyethylene membrane layers 5 and dimethylformamide layers 6. The ultra-high molecular polyethylene membrane layers 5 and the dimethylformamide layers 6 are arranged alternately. In this way, by arranging the microporous membrane to be composed of the ultra-high molecular polyethylene membrane layer 5 and the dimethylformamide layer mixed and melted, the ultra-high molecular polyethylene membrane layer 5 has good chemical corrosion resistance, thereby extending the service life of the fabric body.

[0036] In at least one embodiment of the present invention, Figure 4 As shown, the outer walls of the first microporous membrane layer 21, the second microporous membrane layer 22 and the third microporous membrane layer 23 are all provided with a plurality of film holes 7. The plurality of film holes 7 are arranged parallel to each other and at equal intervals. In this way, the film holes can not only filter tiny particles and impurities to ensure the high purity and quality stability of the fabric body, but also have excellent anti-permeability, so that different film holes can effectively isolate harmful substances, thereby blocking the connection between harmful substances and better facilitating the use of the fabric body.

[0037] The pore size of the film pore 7 can be set according to actual needs, and the embodiment of the utility model does not specifically limit this. For example, in some embodiments, the pore size of the film pore 7 is less than 100 nm.

[0038] In a specific implementation of the present invention, Figure 5 As shown, the polypropylene spunbond fabric layer 3 includes a first antibacterial fiber layer 31 and a second antibacterial fiber layer 32. The first antibacterial fiber layer 31 and the second antibacterial fiber 32 are staggered to form a grid structure. In this way, by setting the first antibacterial fiber layer 31 and the second antibacterial fiber 32 in the polypropylene spunbond fabric layer 3 to be staggered to form a grid structure, the polypropylene spunbond fabric layer 3 has the characteristics of high strength, wear resistance, and folding resistance, and can also prevent the growth of various pathogenic bacteria and harmful bacteria, thereby improving the safety of the fabric body 1, and the polypropylene spunbond fabric layer 3 has the characteristics of low production cost and better use effect.

[0039] Below, in combination with the above-mentioned embodiments of the present application, the use process of the protective isolation fabric is illustrated.

[0040] When using this structure, the microporous membrane layer 2 is formed by mixing and melting the ultra-high molecular polyethylene membrane layer 5 and the dimethylformamide layer 6, and the first microporous membrane layer 21, the second microporous membrane layer 22, and the third microporous membrane layer 23 are connected to each other and bent at 90 degrees and staggered to each other, which can enhance the strength of the fabric body 1, and can have the characteristics of strong hygroscopicity, good heat resistance, and not easy to soften. The ultra-high molecular polyethylene membrane layer 5 has good chemical corrosion resistance, which can prevent the fabric body 1 from being corroded during long-term use, thereby extending the service life of the fabric body 1. The film holes 7 can not only filter tiny particles and impurities, The high purity and quality stability of the fabric body 1 are ensured, and the pore size of the film hole 7 is less than 100nm, which has excellent impermeability, so that different film holes 7 can effectively isolate harmful substances, thereby blocking the connection between harmful substances. By using a polypropylene spunbond fabric layer 3, the polypropylene spunbond fabric layer 3 is composed of a first antibacterial fiber layer 31 and a second antibacterial fiber layer 32, which has the characteristics of high strength, wear resistance, and folding resistance, and can also prevent the growth of various pathogenic bacteria and harmful bacteria, thereby improving the safety of the fabric body 1, and the polypropylene spunbond fabric layer 3 has a low production cost and better use effect. Tight interlayer bonding can reduce the weight of the fabric per unit area while meeting the performance of the protective clothing, and can effectively reduce the amount of solid waste generated from discarded protective clothing, which is conducive to waste minimization.
