Description

[Technical field]

[0001] The present invention relates to a fiber collector that collects fiber debris that falls off clothes during washing and prevents microplastics from being discharged into the ocean. [Background technology]

[0002] In the past, when washing clothes, which involves draining water, fiber debris from the clothes falls off during washing, and the fiber debris that falls off during draining water flows into the ocean together with the drainage, which is known as the problem of microplastics flowing into the ocean. To solve these problems, many woven and knitted fabrics using structural yarns that prevent fiber debris from falling off, as well as clothes and laundry nets using these woven and knitted fabrics, have been developed. On the other hand, as a conventional technology, there are many nonwoven fabrics such as spunbond or thermal bond fabrics with air permeability of 20 to 60 cm 3 / cm 2 Disclosed herein are a water-permeable bag made of .sec (Patent Document 1), a purification device in which inorganic material pieces for adsorbing dirt are filled inside a water-permeable storage bag made of lipophilic fibers (Patent Document 2), a washing machine equipped with a clothing storage body with a mesh size of 10 to 100 μm (Patent Document 3), clothing incorporating a laundry bag having a fabric thickness of approximately 80 μm and an average mesh width in the range of 5 μm to 200 μm (Patent Document 4), and a laundry bag formed from a screen cloth with a mesh width of 5 μm to 200 μm (Patent Document 5).

[0004] However, the storage bodies disclosed in Patent Documents 1, 3, and 5 were inferior in collection ability and strength because the length in the thickness direction was short relative to the fiber length of the fiber waste. In addition, the purification device disclosed in Patent Document 2, in which inorganic material pieces for dirt adsorption were filled in a water-permeable storage bag made of lipophilic fibers, was effective in adsorbing dirt such as oil and grease stains, but did not have the ability to collect fiber waste. The clothing item disclosed in Patent Document 4 with a built-in laundry bag was effective for collecting fiber waste from integrated clothing, but other clothing could not be selected at will, that is, it was inferior in handleability. In addition, woven and knitted fabrics using structural yarns that prevent fiber waste from falling off, which are sold on the market, and clothes using these woven and knitted fabrics, were effective when using the woven and knitted fabrics and clothes, but had the disadvantage that they did not have a suppression means for clothes with different configurations that were already available. Therefore, the object of the present invention is to improve the defects of such conventional technology and provide a fiber collector that is excellent in collection ability, strength, and handleability of fiber waste. [Means for solving the problem]

The fiber collector is characterized by the above.

[0012] The fiber collector of the present invention will be described in detail below with reference to the drawings. As shown in Figs. 1 to 3, the fiber collector 1 of the present invention is composed of a fabric 2, a joint portion 6, and an opening 7. <Dough Form> As shown in Fig. 4, the fabric 2 is made of at least a fiber woven or knitted fabric or a nonwoven fabric. More preferably, a nonwoven fabric is used, which is excellent in productivity and cost. When a nonwoven fabric is used, a papermaking method, a chemical bonding method, a spunbond method, a water jet punch method, a meltblowing method, a flash spinning method, etc. are used, and more preferably, a single or laminated meltblowing method or a spunbond method is preferably used.

[0013] When a woven fabric is used, generally, a plain weave, a twill weave, a satin weave, and variations and multiaxial weaves thereof are preferably used. When a knitted fabric is used, a plain knit, a rib knit, a pearl knit, a tricot, a raschel, etc. are preferably used. The raw material of the fabric 2 may be any of synthetic fibers, semi-synthetic fibers, natural fibers, and animal fibers, but more preferably, in terms of productivity and cost, it is made of a single material or a mixture of multiple materials selected from the group consisting of polyolefins such as polyethylene and polypropylene, polyesters such as polyethylene terephthalate and polylactic acid, polycarbonate, polystyrene, polyphenylene sulfite, and fluorine-based resins. <Diameter of fibers that make up the fabric> The fibers 3 constituting the fabric have a predetermined thickness, i.e., fiber diameter 3b, and there are gaps, i.e., fiber distance 3a, between the fibers constituting the fabric 2. The fiber diameter 3b constituting the fabric 2 constituting the fiber collector 1 of the present invention is 100 nm to 70 μm, which can maintain the size of the micropores at an appropriate level and suppress pressure loss, and is therefore advantageous from the standpoint of fiber waste collection ability and durability. Necessary .

[0014] The fiber diameter 3b constituting the fabric 2 indicates the diameter of a single fiber of the fiber constituting the fabric 2, as shown in Figs.

[0015] If the fiber diameter 3b constituting the fabric 2 is less than 100 nm, there is a problem that the fabric 2 itself is easily deformed by the water flow pressure, and pressure loss is likely to occur, whereas if it is 70 μm or more, the rigidity and pressure loss become large, resulting in poor cleaning properties in washing.The more preferable range is 1 μm to 30 μm.

[0016] The fiber diameter 3b constituting the fabric 2 was determined by cutting out a cross section of the fabric 2, vapor-depositing a platinum-palladium alloy onto the cross section, measuring the single fiber diameter from an image taken with a scanning electron microscope (SEM) (Hitachi S-4000 model), and calculating the simple average value. <Distance between fibers that make up the fabric> The inter-fiber distance 3a constituting the fabric 2 constituting the fiber collector 1 of the present invention is preferably 50 nm or more and 150 μm or less, which has an appropriate size for trapping fiber debris while suppressing pressure loss, and is also preferable from the standpoint of fiber debris collection ability and durability.

[0017] The distance 3a between fibers constituting the fabric 2 represents the average value of the distance between adjacent fibers, as shown in Figs.

[0018] If the inter-fiber distance 3a constituting the fabric 2 is less than 50 nm, there is a problem that the pressure loss is large and the cleaning performance in washing is poor, whereas if it is 150 μm or more, fiber debris is likely to penetrate and the collection performance is poor.

[0019] The inter-fiber distance 3a constituting the fabric 2 was determined by vapor-depositing a platinum-palladium alloy onto the surface of the fabric 2, measuring the inter-fiber distance from an image captured by a scanning electron microscope (SEM) (S-4000 model, manufactured by Hitachi, Ltd.), and calculating the simple average value.

[0020] Means for providing the inter-fiber distance 3a constituting the fabric 2 include adjusting the fiber diameter, adjusting the density of the woven or knitted fabric, or adjusting the spinning conditions such as the polymer discharge amount, nozzle temperature, and air pressure of the nonwoven fabric, and any method may be used. <Textile processing> Such fibers may contain various additives that are commonly used to improve the productivity or properties during the manufacturing process or processing of raw yarns, such as heat stabilizers, antioxidants, light stabilizers, smoothing agents, antistatic agents, plasticizers, thickeners, pigments, flame retardants, antibacterial agents, heat storage agents, water repellents, water absorbents, etc. <Thickness of fabric> The fabric 2 constituting the fiber collector 1 of the present invention has a vertical direction 2a and a horizontal direction 2b, and has a thickness in each direction due to the fibers themselves and the lamination of fibers. The thickness 4 of the fabric 2 constituting the fiber collector 1 of the present invention is 0.15 mm to 1.10 mm, because it has an appropriate length for the fiber waste to be retained in the direction perpendicular to and penetrating the fabric 2 of the fiber collector 1, i.e., in the thickness direction, and from the viewpoint of the fiber waste collection ability. Necessary .

[0021] If the thickness 4 of the fabric 2 is less than 0.15 mm, there is insufficient space to provide resistance when the fiber waste penetrates the fabric 2 of the fiber collector 1, and the fiber waste easily passes through the fabric 2, resulting in poor collection performance, while if it is 1.10 mm or more, the rigidity of the fiber collector 1 increases, resulting in poor handling and cleaning performance in washing. A more preferable range is 0.2 mm to 0.6 mm.

[0022] The thickness 4 of the fabric 2 is a value measured based on JIS L 1096 (2010) 8.4-A method, and the pressure conditions were 0.5 kPa for nonwoven fabrics, 0.7 kPa for knitted fabrics, and 23.5 kPa for woven fabrics.

[0023] The thickness 4 of the fabric 2 can be imparted by adjusting the fiber diameter, bulking the fibers, composite spinning of the fibers, or shrinkage caused by partial dissolution, and any of these methods may be used. <Bulkiness> It is preferable to impart volume per unit weight of the fabric 2 to the fiber collector 1 of the present invention, that is, bulkiness, in order to provide an appropriate collection space for collecting fiber waste inside the fabric 2 of the fiber collector 1 and to further increase the collection efficiency of the fiber waste. teeth 3cm 3 / g or more 20cm 3 / g or less.

[0024] Bulkiness: 3cm 3 If it is less than 20 cm / g, the spatial volume of the fabric 2 of the fiber collector 1 is insufficient relative to the volume of the fiber waste, i.e., the spatial volume defined by the length and diameter of the fiber waste, and the fiber waste easily passes through the fabric 2, resulting in poor collection performance. 3 If the thickness is more than 6 cm / g, the stiffness and pressure loss will increase, resulting in poor cleaning properties. 3 / g~15cm 3 / g range.

[0025] The bulkiness referred to here is the volume per unit weight of the fabric 2 calculated by the following formula.

[0026] Bulkiness [cm 3 / g] = Fabric thickness [cm] / Fabric weight [g / cm 2 〕 Fabric thickness: The thickness measured in centimeters according to JIS L 1096 (2010) 8.4-A method. Pressure conditions are 0.5 kPa for nonwoven fabrics, 0.7 kPa for knitted fabrics, and 23.5 kPa for woven fabrics.

[0027] Fabric weight: The weight per unit area measured according to JIS L 1096 (2010) 8.3.2-A method, expressed in g / cm 2 The value calculated by <Metsuke> As a means for achieving the preferred bulkiness, it is preferable to reduce the basis weight and / or thickness of the fabric 2, since this increases the volume per unit weight, i.e., increases the bulkiness.

[0028] Fabric 2 has a basis weight of 20g / m 2 If it is less than 150 g / m, the fabric 2 itself is easily deformed by the water flow pressure, causing pressure loss, and there is a problem that the strength and abrasion resistance are easily reduced. 2 If it is more than this, the weight of the fiber collector 1 increases, and handling becomes poor. 2~100g / m 2 The range is.

[0029] The basis weight is measured based on JIS L 1096 (2010) 8.3.2-A method and is measured per 1 m under standard conditions. 2 Mass per unit (g / m 2 ) is what was sought. <Fiber morphology> As another means for achieving the preferred bulkiness, the fibers constituting the fiber woven or knitted fabric or nonwoven fabric constituting the fabric 2 may be at least partially made of split fibers, textured yarns, or composite fibers. Necessary As a result, since the fibers themselves have voids, the weight per unit volume is reduced, and the bulkiness is within the desired range. can In addition, when collecting fiber waste, the fiber waste is likely to be caught not only in the gaps between the fibers 3 constituting the fabric, but also in the gaps inside the fibers, so that the fiber waste is also easily caught in the gaps between the fibers 3 constituting the fabric, so that the fiber waste is also easily caught in the gaps inside the fibers, so that the fiber waste is ... Necessary There are the following methods for using split fibers, textured yarns, or composite fibers at least in part. For example, when the fabric 2 is a woven fabric, there is a method of weaving using split fibers, textured yarns, or composite fibers for the fibers in the warp direction, i.e., the warp threads. Alternatively, there is a method of weaving using them for the fibers in the horizontal direction, i.e., the weft threads. Alternatively, there is a method of weaving using them for both the warp and weft threads.

[0030] For example, when the fabric 2 is a weft knitted fabric, there is a method in which the fibers to be inserted are switched for each course, and either split fiber, textured yarn, or composite fiber is used in all courses, or mixed in a fixed ratio. For example, when the fabric 2 is a nonwoven fabric, there is a method in which fibers consisting of short fibers or long fibers of either split fiber, textured yarn, or composite fiber are blended in the entire amount or in a fixed ratio to form the fabric. In either method, the preferred blending ratio or blending ratio is in the range of 10 to 100%, and more preferably in the range of 40 to 100%. As a preferred form of split fiber, there is a method in which at least two kinds of components with different shrinkage rates are compositely spun, and then voids are generated between the components due to the shrinkage difference by heat treatment to form split fiber, or a method in which at least two kinds of components are compositely spun, and then one of the components is subjected to a dissolution treatment to form voids due to dissolution to form split fiber, and any of these may be used. More preferably, a method in which at least two kinds of components having different shrinkage rates are conjugated and then heated to generate voids between the components due to the shrinkage difference, thereby forming splittable fibers, is preferred because of its excellent productivity.

[0031] As the cross-sectional form of the splittable fiber, a splittable composite fiber having a form in which the first component is radially arranged in the core and the second component is joined and arranged in the radial wedge portion in the sheath is particularly preferred. In particular, when a splittable fiber is made of a core having a star-shaped cross section, for example, 6 to 12 apexes, made of one first component, and 6 to 12 second components are arranged in the wedge portion around it, the gap between the core and the surrounding wedges increases the bulkiness, and fiber waste is easily inserted into the gap, making it excellent in collection. In addition, it is suitable because it has the characteristics of being soft yet having moderate stiffness and stiffness, and because the difference in optical properties of the two types of components allows it to exhibit a velvety, elegant luster and color. As a preferred form of the processed yarn, any of the elastic bulky processing methods such as false twisting, rubbing, and pushing, and the non-elastic processing method such as air injection, may be used, and more preferably, the elastic bulky processing method is excellent in bulkiness, and even more preferably, the false twisting method is excellent in collection and productivity, making it suitable.

[0032] The preferred physical properties of the processed yarn are bulkiness of 5 to 50 cm. 3and / or the number of twists is 200 to 1,000 / m, and / or the number of false twist crimps of the fibers constituting the fiber bundle is 30 or more / 20 cm.

[0033] The bulkiness here is measured based on JIS L 1013 8.16A, and the number of twists is measured based on JIS L 1013 8.13.1. The number of crimps is the number of crimps per meter. As a preferred form of composite fiber, there is a method of bimetallic composite spinning of at least two kinds of components with different shrinkage rates, followed by heat treatment to generate crimps and shrinkage due to shrinkage difference between the components, a method of bimetallic composite spinning of at least two kinds of components with different elongation rates, followed by crimps and shrinkage due to elongation stress difference between the components, and a method of sea-island composite spinning of at least two kinds of components, followed by elution treatment of one of the components, and any of these may be used. More preferably, a method of bimetallic composite spinning of at least two kinds of components with different shrinkage rates bonded together in a side-by-side type, followed by heat treatment to generate crimps and shrinkage due to shrinkage difference between the components, is preferred because it provides excellent bulkiness and collectability due to shrinkage.

[0034] As a preferred physical property of the composite fiber, the average value of the irregularity, i.e., the value obtained by dividing the circumscribed circle diameter by the inscribed circle diameter, is 1.0 to 6.0, since the coil crimp association is unlikely to occur between the single yarns constituting the composite fiber, and each yarn is allowed to independently express crimp, so that the fabric can obtain a feeling of fullness specific to the irregular cross section, i.e., bulkiness and collectability, which is preferred. In addition, in consideration of the spinning stability, the irregularity is more preferably 1.5 to 3.0.

[0035] The irregularity here is defined as the diameter of the circumscribed circle of the cross section of each single yarn constituting the composite fiber, D 1 The distance between the two intersection points of the composite interface and the fiber surface of the cross section of each single yarn is D 2 When the irregularity degree is D 1 / D 2The fiber collector 1 of the present invention is made by using at least a part of any of the above-mentioned fibers in the fiber woven or knitted fabric or nonwoven fabric constituting the fabric 2, and therefore the bulkiness of the fabric 2 can be set within a preferred range without carrying out physical or chemical treatment on the surface of the fabric 2, resulting in excellent collection properties, productivity, and cost. <Breathability> The preferred air permeability range of the fabric 2 constituting the fiber collector 1 of the present invention is 30 cm 3 / cm 2 / sec~300cm 3 / cm 2 / sec range.

[0036] The breathability indicates the ease with which air can pass through the fabric 2. Breathability 30cm 3 / cm 2 If it is less than 300cm / sec, the pressure loss due to the water flow is large, and the washing performance is poor. 3 / cm 2 If the speed is more than 50 cm / sec, the fiber waste will easily pass through the fabric 2, resulting in poor collection performance. 3 / cm 2 / sec~150cm 3 / cm 2 / sec range.

[0037] The air permeability is measured based on JIS L 1096 8.26.1 A method (Fragile type method) and the unit is cc / cm 2 This is calculated in / sec to the first decimal place.

[0038] The breathability can be imparted by any method, such as adjusting the density, basis weight, average fiber diameter, or thickness of the woven or knitted fabric, or adjusting the spinning conditions such as the polymer discharge amount, nozzle temperature, or air pressure of the nonwoven fabric. <Tensile strength> Since the fiber collector 1 of the present invention is subjected to mechanical forces and abrasion during washing, tension during handling, and the load of clothing and abrasion, it is preferable that the fabric 2 constituting the fiber collector 1 has tensile strength and abrasion resistance in order to increase durability in long-term use from washing to handling. The preferred range of tensile strength of the fabric 2 is 20 N / 5 cm or more in the warp and weft directions. If the tensile strength of the fabric 2 is less than 20 N / 5 cm, there is a problem that it is prone to breakage or bursting due to mechanical forces during washing, tension during handling, and the load of clothing.

[0039] Considering the ease of crushing and disassembly at the time of disposal, a more preferable range is 20 N / 5 cm to 300 N / 5 cm.

[0040] The tensile strength of the fabric 2 was measured based on JIS L 1096 8.14 Tensile strength and elongation, Method A (strip method).

[0041] Means for imparting tensile strength to the fabric 2 include selecting fibers with high tensile strength, adjusting the fiber diameter, adjusting the density of the woven or knitted fabric, or adjusting the spinning conditions such as the polymer discharge amount, nozzle temperature, and air pressure of the nonwoven fabric, and any of these methods may be used. <Wear resistance> The preferred range of abrasion resistance of the fabric 2 is at least grade 3 in both the warp and weft directions. If the abrasion resistance of the fabric 2 is less than grade 3, there is a problem in that it is prone to wear and tear such as abrasion destruction and fraying due to wear during washing and handling.

[0042] The abrasion resistance of the fabric 2 is a value measured under a load condition of 2.45 N based on the Taber method described in JIS L 1913:2010 (6.6.1).

[0043] Means for imparting abrasion resistance to the fabric 2 include selecting fibers with high abrasion resistance, adjusting the fiber diameter, changing the structure of the woven or knitted fabric, or adjusting the spinning conditions such as the polymer discharge amount, nozzle temperature, and air pressure of the nonwoven fabric. Any of these methods may be used. <Water resistance> In addition, the fabric 2 constituting the fiber collector 1 of the present invention is preferably made to have a pressure resistance that allows water to easily pass through, that is, to easily allow water to pass through, in order to wash clothes and the like stored inside the fiber collector 1 during washing. The water pressure resistance of the fabric 2 is 1,000 mmH 2 It is preferable that the water resistance of the fabric is 1,000mmH or less. 2 If it exceeds 0, the water does not pass through the fabric 2 sufficiently, and the washing performance of the clothes stored inside the fiber collector 1 is poor. 2 Less than O.

[0044] The water pressure resistance of the fabric 2 is a value measured based on the JIS L 1092-B method. <Shape of dough edge> In addition, since the fiber collector 1 of the present invention uses a fabric 2 of a predetermined size and a predetermined shape, the fabric 2 used in the present invention has a fabric end 5 as shown in FIG. 3, and the fiber collector 1 has a structure that contains the fabric end 5. In the fiber collector 1 of the present invention, in order to prevent the fibers 3 constituting the fabric from falling off from the fabric end 5, which is a component of the fiber collector 1, during washing, it is preferable that the fabric end 5 is welded, fused, or covered, from the viewpoint of preventing the fibers 3 constituting the fabric from being exposed at the fabric end 5 and preventing the outflow of fiber waste. For example, as shown in FIG. 3, by covering the fabric end 5 with piping and joining the ends together by machine sewing, the fabric end 5 is not exposed, and the fibers 3 constituting the fabric can be kept within the joint 6, making it possible to prevent the fibers 3 constituting the fabric from flowing out from the fabric end 5. <Joint part> In the fiber collector 1 of the present invention, the joint 6 is formed by overlapping the fabrics 2 at least twice and fixing them in close contact or integrating them as shown in FIG. 3. The preferred form of the joint 6 is formed by any process selected from fusion, adhesion, and machine sewing. As the fusion processing method, the heat press method, the high-frequency heating method, and the ultrasonic processing method are mainly preferably used, but any of them may be used, and the ultrasonic processing method is more preferable because of its excellent cost and productivity. As the adhesion processing method, in addition to a method in which an adhesive resin is interposed between the opposing fabrics 2 and adhesion is mainly performed using heat press, high-frequency heating, and ultrasonic waves, a method in which a seam tape is adhered to the seam after sewing the opposing fabrics 2 with a sewing machine is preferably used, but any of them may be used, and the heat press method with an adhesive resin interposed is more preferable because of its excellent cost and productivity. As the sewing method by sewing machine, methods such as overedge stitching, piping, and lock stitching are preferably used, but any of them can be used. More preferably, as shown in FIG. 3, piping stitching is preferred because it keeps the fabric edge 5 from being exposed and keeps the fabric fibers 3 within the joint 6, thereby preventing the fabric fibers 3 from flowing out from the fabric edge 5. <Opening> The fiber collector 1 of the present invention has an opening 7, i.e., an opening portion, which allows clothes to be freely put in and taken out. A preferred embodiment of the opening 7 may be either the state in which the fabric end 5 is released as shown in FIG. 2, or the state in which a fastening member is interposed between the fabrics as shown in FIG. 1 and made openable and closable. More preferably, the fastening member is interposed between the fabrics and made openable and closable, which is excellent in handleability. The fabric 2 used in the fiber collector 1 of the present invention may be formed as a single piece of fabric 2 by laminating a plurality of fiber layers, and each fiber layer may have a different configuration, for example, fiber diameter, pore size, raw material, structure, thickness, and basis weight. Furthermore, the fiber collector 1 of the present invention may be used in combination with a plurality of different fabrics 2. For example, in the two fabrics 2 constituting the fiber collector 1 of FIG. 3, one may be a three-layer nonwoven fabric in which a polypropylene spunbond nonwoven fabric, a polyethylene meltblown nonwoven fabric, and a polypropylene spunbond nonwoven fabric are laminated, and the other may be a polyester spunbond nonwoven fabric. EXAMPLES

[0045] The present invention will be described in more detail below with reference to examples and comparative examples, but the present invention is not limited thereto. The fiber collector 1 used in the examples and comparative examples was evaluated by the following method. [measurement] [Fiber diameter 3b that composes fabric 2] The fiber diameter 3b constituting the fabric 2 of the fiber collector 1 was determined by cutting out a cross section of the fabric 2, vapor-depositing a platinum-palladium alloy onto the cross section, measuring the single fiber diameter from an image taken with a scanning electron microscope (SEM) (S-4000 model, manufactured by Hitachi, Ltd.), and calculating the simple average value. [Distance between fibers 3a constituting fabric 2] The inter-fiber distance 3a constituting the fabric 2 of the fiber collector 1 was determined by vapor-depositing a platinum-palladium alloy onto the surface of the fabric 2, measuring the inter-fiber distance from images taken with a scanning electron microscope (SEM) (S-4000 model, manufactured by Hitachi, Ltd.), and calculating the simple average value. [Fabric 2 thickness 4] The thickness 4 of the fabric 2 of the fiber collector 1 was measured based on JIS L 1096 (2010) 8.4-A method, and the pressure conditions were 0.5 kPa for nonwoven fabrics, 0.7 kPa for knitted fabrics, and 23.5 kPa for woven fabrics. [Bulkiness] The bulkiness of the fiber collector 1 was calculated by calculating the volume per unit weight of the fabric 2 using the following formula.

[0046] Bulkiness [cm 3 / g] = thickness of fabric 2 4 [cm] / basis weight of fabric 2 [g / cm 2 〕 Thickness 4 of fabric 2: The thickness measured in cm according to JIS L 1096 (2010) 8.4-A method. The pressure conditions are 0.5 kPa for nonwoven fabrics, 0.7 kPa for knitted fabrics, and 23.5 kPa for woven fabrics.

[0047] Fabric 2 weight: Weight per unit area measured according to JIS L 1096 (2010) 8.3.2-A method in g / cm2 The value calculated using [Breathability] The air permeability of the fiber collector 1 is measured based on JIS L 1096 8.26.1 A method (Fragile type method) and the unit is cc / cm 2 The calculation was done in / sec to the first decimal place. [Tensile strength of fabric 2] The tensile strength of the fabric 2 of the fiber collector 1 was measured based on JIS L 1096 8.14 Tensile strength and elongation, Method A (strip method). [Wear resistance of fabric 2] The abrasion resistance of the fabric 2 of the fiber collector 1 was measured under a load condition of 2.45 N based on the Taber type method described in JIS L 1913:2010 (6.6.1). [Collection rate] The test sample used was 100 g of raw cotton consisting of a 1:1 mixture of polyethylene terephthalate (hereinafter referred to as PET) fibers with a fiber length of 5 mm and a fineness of 0.6 dtex (fiber diameter of 20 μm) and PET fibers with a fiber length of 5 mm and a fineness of 2.2 dtex (fiber diameter of 71 μm). This sample was placed in a fiber collector and the collection rate after washing three times using the JIS L 1930 C4N method was calculated using the following formula.

[0048] Each weight was measured after leaving it to stand for 24 hours in an environment of 20°C and 65% humidity, and was calculated to two decimal places.

[0049] Collection rate [%]={1+(B 2 -B 1 ) / S 1}×100 S 1 : Sample weight before washing B 1 : Total weight of fiber collector and sample before washing B 2 : Total weight of fiber collector and sample after washing [Cleanliness] Based on JIS C 9606 (2007) 8.14 Laundry performance test - Detergency (DS), the degree of detergency after washing once with the JIS L 1930 C4N method while artificially soiled cloth was stored in a fiber collector was calculated using the following formula. Note that the artificially soiled cloth used was a wet soiled cloth sold by the Laundry Science Association.

[0050] Cleanliness [%] = {(R w -R s ) / (R o -R s )}×100 R w : Reflectance of artificially soiled cloth after washing R s : Reflectance of artificially soiled cloth before washing R o : Reflectance of white cloth before artificial soiling of artificial soiling cloth [evaluation] [Fiber waste collection ability] The fiber debris collection ability of the fiber collector 1 during washing was evaluated according to the criteria in Table 1.

[0058] [Table 3]

[0059] The fiber collectors of Examples 1 to 4 were excellent in washing cleanability by setting the pore size, thickness, and bulkiness between the fibers constituting the fabric within preferred ranges. The fiber collectors of Examples 1 to 3 were excellent in durability by setting the fiber diameter of the fabric within preferred ranges. The fiber collectors of Examples 1 to 2 were excellent in fiber debris collection by setting the fabric end to a preferred shape. The fiber collector of Comparative Example 1 did not have the distance between the fibers constituting the fabric and breathability, and had low thickness, bulkiness, tensile strength, and abrasion resistance, so water did not flow in and out of the fiber collector during washing, and the fiber debris remained inside, and the collection rate showed a high numerical value, but the lack of water flow resulted in poor washing cleanability and poor durability. The fiber collector of Comparative Example 2 was inferior in fiber debris collection and durability by setting the distance between the fibers constituting the fabric, thickness, and bulkiness, and low abrasion resistance. The fiber collector of Comparative Example 3, like Comparative Example 1, did not have the interfiber distance and breathability that make up the fabric, and therefore showed a high collection rate, but did not allow water to pass through and was inferior in washability. In other words, the more the fiber collector of the present invention satisfies the more requirements of the invention it becomes a fiber collector that is more excellent overall.
