  • a fiber catcher as disclosed herein is an apparatus that can effectively and efficiently remove fibers that are present in an aqueous or gaseous environment, such as, but not limited to, a washing machine, a clothes dryer, a graywater pipe, a waste treatment effluent, a waterway (e.g., canal, river, stream, etc.), or other body of water.
  • the fiber catcher can have multidirectional movement and can be at least partially buoyant in typical aqueous solutions.
  • a fiber catcher according to the present disclosure can be deployed directly into a residential or commercial washing machine or clothes dryer so as to collect fibers, thereby preventing those fibers from sticking to clothing or entering a downstream water source or the environment.
  • a fiber catcher 100 has an outer portion 102 and an inner portion 104.
  • both inner portion 104 and outer portion 102 are generally spherical.
  • Outer portion 102 is sized and configured to allow for sufficient water flow through fiber catcher 100.
  • outer portion 102 may be a sphere approximately 5 to 12 or more centimeters in diameter (which may be a convenient size for typical laundry machines, although it will be understood that other shapes and sizes are possible for different applications) and include several openings surrounded by supports, e.g., support 107.
  • This cage-like structure of outer portion 102 is configured so as to not require any particular direction of water flow.
  • outer portion 102 allows for omnidirectional capture of fibers (by inner portion 104, which is described in more detail below) irrespective of the direction of water flow or orientation of fiber catcher 100.
  • the permeability of outer potion 102 can be such that items of a certain size or greater (i.e., items that tend to be unable to pass through the opening under normal conditions), such as socks, fish, etc. (also referred to herein as bulk or bulkier items), are kept from accessing inner portion 104.
  • Outer portion 102 may be constructed from two hemispheres (e.g., 103a and 103b as shown in FIG. 2) that can be releasably attached to each other to allow access to inner portion 104 as necessary, such as for cleaning.
  • hemispheres 103a and 103b may be secured together via threads 101 as shown in FIG. 2.
  • Outer portion 102 may be made of any material suitable for an intended use of fiber catcher 100, such as in residential and/or commercial washers and dryers, including plastics and rubbers, and preferably thermoplastic elastomers (TPE), such as, but not limited to, TPE-0 (thermoplastic elastomeric material based on olefins, mainly a polypropylene (PP)/ethylene propylene diene monomer (EPDM)), TPE-U (thermoplastic elastomeric materials based on urethane), and TPE-Z (crosslinked thermoplastic elastomeric material based on polyolefin PP/EPDM mixture), as well as polypropylene, silicones, and metals.
  • TPE thermoplastic elastomers
  • thermoplastic elastomers or silicones may be selected.
  • polypropylene or metals may be selected.
  • commercial laundry washing machines may have a range of water temperatures from about 5 degrees Celsius to about 66 degrees Celsius and commercial dryers may have a range of air temperatures from about 15 degrees Celsius to about 100 degrees Celsius. The ranges for commercial washing and drying machines exceed the operating ranges of residential machines in most, if not all, instances.
  • outer portion 102 and inner portion 104 are configured such that inner portion 104 and outer portion 102 can rotate with respect to each other in the presence of flowing or moving water so as to reduce horizontal displacement of fiber catcher 100. This may be accomplished by, for example, having inner portion 104 be connected to outer portion 102 by the ends of an axis of inner portion 104 such that inner portion 104 and outer portion 102 can rotate independently with respect to that axis. For example, as shown in a partially assembled embodiment in FIG.
  • inner portion 104 may include a substantially tubular piece 109 that has ends designed to mate with outer portion 102 on both ends via a suitable mechanism that secures tubular piece 109 while allowing tubular piece 109 to rotate in either direction, such as appropriately sized cutouts 111 (e.g., 111a and 11 lb, which can be seen more clearly in FIG. 2) in outer portion 102, as shown in FIG. 3.
  • tubular piece 109 serves as an axis of rotation of inner portion 104 to rotate within outer portion 102 while outer portion 102 can rotate around that axis largely unencumbered as well.
  • inner portion 104 is configured to collect fibers, and may include arms 106 (e.g., 106a-106f) with a multitude of fingers or teeth 108 (e.g., 108a-108d).
  • inner portion 104 includes a sufficient number of arms 106 projecting from a central portion and sized to form an approximate sphere shape that fits within outer portion 102.
  • Teeth 108 in a preferred embodiment project out from arms 106 at an approximately 90 degree angle or any suitable angle (or assortment or pattern of angles) that encourages the collection of fibers on teeth 108 as water flows past the arms 106 of inner portion 104.
  • inner portion 104 is configured in any way to enable the capture of fibers, such as to include a rough and relatively large capture surface area relative to the volume of inner portion 104 while still maintaining an overall permeable structure.
  • fibers are captured by inner portion 104 and the water flows out of inner sphere 104 and then out of outer sphere 102 freer of fibers.
  • Inner portion 104 may be made of any material suitable for an intended use of fiber catcher 100, such as in residential and/or commercial washers and dryers, including plastics and rubbers, and preferably thermoplastic elastomers, such as, but not limited to, TPE-O, TPE-U, and TPE-V, as well as polypropylene, silicones, and metals. In applications in which more resiliency is desirable, thermoplastic elastomers may be selected. In applications in which more rigidity or durability is desirable, polypropylene or metals may be selected.
  • inner portion 104 and outer portion 102 collect fibers, thereby removing them from the water, whether that water is in a washing machine, wastewater outflow or a public waterway.
  • fiber catcher 100 can also remove fibers from air when air passes through and as such may be used in clothes dryers, for example.
  • fiber catcher 100 is buoyant. Buoyancy serves to place or allow fiber catcher 100 to make its way to the surface of the water source, e.g., to the top of the wash, even if it starts at the bottom (of, for example, a top load washer machine).
  • fiber catcher 100 is not so buoyant so that fiber catcher 100 sits too high out of the water; rather, in a preferred embodiment fiber catcher 100 displaces about half its weight of water.
  • fiber catcher 100 preferably is buoyant enough to stay on the top of the wash water, about half in and half out of the water.
  • fiber catcher 100 is configured to pick up those fibers that tend to rest at the surface of the wash water thanks to the presence of soap.
  • Soap has a high fat content and is generally made with a saponification process, relying on surfactants to actively remove dirt and hair from clothes.
  • a washing machine's action that causes the agitation of the wash water, coupled with surfactants in laundry soap, removes the dirt and hair from our clothes. Because soap has fats, it floats and concentrates the largest amounts of fibers at the top of the wash.
  • fiber catcher 100 is configured to rest below the water surface or near an exit water flow.
  • some washing machines do not include a central agitator and do not use an amount of water that would allow fiber catcher 100 to move around the surface.
  • fiber catcher 100 can have a density so as to float below the water's surface, be weighted or designed to have a flat-bottom (e.g., only one hemisphere of the outer portion of fiber catcher 100 is employed), so that fiber catcher 100 rests at the bottom of the machine and moves with the action of the drum.
  • fiber catcher 100 when in use in a washing machine fiber catcher 100 starts to move around the wash once the washing machine has filled with water.
  • a typical washing machine has a drum that moves in multiple directions during the agitation cycle and makes relatively frequent stops/reverses.
  • the drum stops the inertia of fiber catcher 100 makes it roll to a new area of the wash, thereby collecting more fibers in that area.
  • inner portion 104 rotates in a way that can generally be considered eccentric. By eccentric, what is meant is not a rhythmic movement; for example, sometimes the rotation is quick and other times the rotation is languid.
  • inner portion 104 is generally a sphere that is split into hemispheres, where one of the hemispheres is heavier than the other, which can cause additional motion of inner portion 104.
  • the weight difference between the hemispheres of inner portion 104 is due to having one hemisphere's catch arms longer than the other.
  • the weight difference between the hemispheres of inner portion 104 is due to a reduction in the number of fingers on the catch arms of one of the
  • outer portion 102 and inner portion 104 operate on different planes of movement, which can allow more water to go through fiber catcher 100 and facilitate the collection of more fibers.
  • fiber catcher 100 allows fiber catcher 100 to move through and/or interact with more of the water in the washing machine more often. Some of this movement (i.e., rotational and translational) is driven using energy provided by hydrodynamics, gravity, and the agitator of the washing machine.
  • a fiber catcher as described herein can be used in other environments besides the washing machine examples discussed above.
  • wastewater treatment plants do not have the ability to effectively filter out microfibers and thus once household effluent is treated, the fibers are being flushed out into waterways, lakes, rivers, and oceans.
  • the outflow of a wastewater treatment plant is generally linear (as opposed to agitated as in a washing machine)
  • any one moment about half of fiber catcher 200 extends inside effluent pipe 212 and the other half outside effluent pipe 212 (where the pipe is sealed at this junction to prevent water egress).
  • outside of pipe 212 there can be a comb-like self-cleaning device 205 cleaning the other half of the sphere as inner portion 204 rotates under the influence of a direction of water flow 201.
  • fiber catchers could be deployed by attaching them to buoy lines in harbors and rivers or strategically placed on stationary moorings.
  • a fiber catcher 300 includes arms 306 (e.g., 306a-306f), fingers or teeth 308, (e.g., 308a-308f) and protuberances 310 (e.g., 310a-310c) (these aspects can be seen more clearly in FIG. 9, which is a view of a disassembled part of fiber catcher 300). While fiber catchers of the present invention may be constructed in any suitable manner, in a preferred embodiment, arms 306 extend from a central axis, such as a rod or spindle 314, and are sized and distributed so that fiber catcher 300 forms a generally spherical shape, although it will be understood that other shapes are possible.
  • arms 306 extend from a central axis, such as a rod or spindle 314, and are sized and distributed so that fiber catcher 300 forms a generally spherical shape, although it will be understood that other shapes are possible.
  • arms 306 may be arranged generally initially in parallel with each other in a direction orthogonal to the central axis, that is, if spindle 314 is oriented in a vertical direction, arms 306 will extend out from spindle 314 horizontally in parallel with each other (as can be seen most clearly in FIG. 6).
  • arms 306 in a preferred embodiment have flexibility and elasticity and thus in use can deviate from any default orientation during use, for cleaning, or if forced.
  • arms 306 may be staggered, such as in a spiral configuration, so that arms 306 that are vertically adjacent are not aligned right above or below one another (as can be seen for example in FIGS. 6-7).
  • Such preferred configurations may be accomplished for example by assembling arms 306 in groups connected to discs 316 (e.g., 316a-316b in FIGS. 9-1 lb) and stacking said discs 316 on central spindle 314.
  • FIG. 8 depicts spindle 314, which may include pin receptacles 315 (e.g., 315a and 315b) near one end or both ends for securing assembled discs 316 in place in a manner described below.
  • arms 306 extend out from a ring 318 (e.g., 318a in FIG. 9) with an opening that is designed to fit on spindle 314.
  • a ring 318 e.g., 318a in FIG. 9
  • disc 316b is shown on spindle 314.
  • any suitable mechanism may be used to secure discs 316 to spindle 314 to form an exemplary fiber catcher 300.
  • One technique is to include, near a top and bottom on spindle 314, pin receptacles 315 (e.g., 315a and 315b) or the like that can receive pins 323 (e.g., top pin 323a and bottom pin 323b) as shown in FIG. 13.
  • discs 316 that are to be placed near the top and bottom of spindle 314 may include sleeves or slots 325 that are designed to have pins 323 pass through. As shown in FIG. 1 lb, for example, slot 325b runs through the underside of ring 318a of disc 316b, and, as shown in FIG. 13, slot 325a runs through the topside of disc 316c.
  • discs 316 can be secured to spindle 314 by placing disc 316 on spindle 314 and aligning slot 325 with pin receptacle 315 and then inserting pin 323 through spindle 314 as implied in FIG. 13. With a single disc 316 secured in this way to spindle 314, additional discs 316 may be added onto spindle 314 to form fiber catcher 300.
  • rings 318 may include interlocking counterpart structures 320 (e.g., 320a- 320d in FIG. 9 and 320e-320f in FIG. 11a) such that when stacked on spindle 314, rings 318 are fixed in position relative to adjacent rings 318, which allows arms 306 to be placed in any desired pre-determined configuration with respect to arms 306 on adjacent rings 318.
  • arms 306 can be arranged to have arms above or below on adjacent discs be stacked, staggered, or in any pattern or arrangement.
  • interlocked discs 316 are interlocked with at least one disc 316 that is secured to spindle 314 in such a manner that the secured disc 316 is locked such that it cannot move radially on spindle 314, then all assembled discs 316 will be locked with respect to their radial orientations. In this way, a fiber catcher 300 may be assembled so that arms 306 remain in any desired pattern.
  • a generally spherical shape for fiber catcher 300 may be achieved by placing discs 316 with relatively short arms 306 (e.g., arms 306a-306c on disc 316b in FIG. 11a) near a top and a bottom of spindle 314 (as in FIG. 13 with disc 316b and 316c) and placing discs 316 with progressively relatively longer arms toward a middle section of spindle 314, with the longest arms 306 (e.g., arms 306d-306f on disc 316a in FIG. 9) in the middle.
