Definitions
- the present invention generally relates to creating magnetic scrims for easier processing for molding applications.
- foams such as polyurethanes are combined with other textile layers such as scrims during the molding process.
- the scrims can give the polyurethane additional strength and other characteristics such as fire resistance.
- the invention relates to a magnetic scrim containing a scrim which contains a plurality of yarns and a magnetic coating covering at least a portion of the yarns of the scrim.
- the magnetic coating which contains magnetic elements dispersed in a binder, where the magnetic coating is at least about 40% by weight magnetic elements, and where the magnetic coating has an areal density of at least twice the areal density of the scrim.
- Figure 1 illustrates one embodiment of a magnetic scrim.
- Figure 2 is a photograph of one embodiment of the scrim (before being coated with the magnetic coating).
- the magnetic scrim 10 contains a scrim 100 having a first side 100a and a second side 100b.
- the scrim 100 contains a plurality of yarns.
- the magnetic scrim 10 also contains a magnetic coating 120 that covers at least a portion of the yarns of the scrim 100.
- This magnetic scrim 10 would be placed in a mold with at least one magnet to hold the scrim in place while the mold is prepared and polyurethane (or other moldable material) is introduced and then cured in the mold.
- the term "scrim” shall mean a fabric having an open construction used as a base fabric or a reinforcing fabric, which may be
- the scrim contains a plurality of yarns and the yarns may be adhesively or thermally bonded or may be unbonded to each other.
- the scrim 100 may be any suitable scrim including any suitable light weight woven, knit, or nonwoven fabric.
- the scrim layer is a weft inserted warp knit scrim.
- a weft inserted warp knit scrim 100 contains a plurality of warp yarns 110, weft yarns 1 11 , and stitching yarns 113.
- the stitching yarns 1 13 may have any suitable stitching pattern, including tricot stitches or pillar stitches, or other stitches.
- the weft yarns 1 1 1 can be laid in every course (every row of stitches from the stitching yarn), every second course (every second row of stitches from the stitching yarn), every third course (every third row of stitches from the stitching yarn) or more. How open or closed (how close together the yarns are within the scrim 100, is determined by the types and sizes of the yarns and the desired properties of the scrim 100 and magnetic scrim 10.
- One suitable scrim, not coated with the magnetic coating yet, is shown in Figure 2.
- the scrim 100 comprises a plurality of yarns in a warp direction and a plurality of yarns in a weft direction defined to be approximately perpendicular to the warp direction.
- at least a portion of the plurality of yarns in a weft direction are polyester texturized polyester yarns.
- the yarns of the scrim can be any suitable yarns, include any suitable materials, structure, and thickness.
- the yarns making up the strip-shaped textile forming the strip-shaped substrate 200 may be any suitable yarn.
- "Yarn”, in this application, as used herein includes a monofilament elongated body, a multifilament elongated body, ribbon, strip, fiber, tape, and the like.
- the term yarn includes a plurality of any one or combination of the above.
- the yarns may be of any suitable form such as spun staple yarn, monofilament,
- the yarns are monofilament. In another embodiment, the yarns are multifilament. In another embodiment, the yarns contain mono and multifilaments. In one preferred embodiment, at least a portion of the yarns are texturized as this has been found to be beneficial in the coating process. In one embodiment, the weft yarns of the weft inserted warp yarn knit scrim are texturized.
- Some suitable materials for the yarns include polyamide, aramid (including meta and para forms), rayon, PVA (polyvinyl alcohol), polyester, polyolefin, polyvinyl, nylon (including nylon 6, nylon 6,6, and nylon 4,6),
- PEN polyethylene naphthalate
- the yarns comprise polyester yarns.
- the yarns of the magnetic scrim 10 consist essentially of polyester yarns (defined to be mean at least 98% of the yarns are polyester yarns).
- the magnetic scrim 10 contains a magnetic coating 120.
- the magnetic coating 120 preferably covers at least a portion of yarns of the scrim 100. More preferably, the magnetic coating 120 covers essentially all of the surface area of the yarns in the scrim (defined as covering at least 95% of the surface area of the yarns).
- the magnetic coating 120 contains magnetic elements and a binder.
- the magnetic elements 120 have a persistent magnetic field.
- the term“persistent magnetic field” refers to a magnetic field that persists for an extended period of time, such as the magnetic field of a traditional permanent magnet.
- the magnetic elements and magnetically responsive elements are magnetically attracted when in close proximity to each other. This magnetic attraction produces a force that draws and reversibly holds together the magnetic scrim 10 and the mold.
- the magnetic elements can be any suitable material that has a persistent magnetic field.
- the magnetic elements can be permanent magnets made from materials such as iron, nickel, neodymium, cobalt, alloys of such metals (e.g., BaFe3C>4, SrFe3C>4, AINiCo) and alloys of rare earth metals, such as NdFeB and CoSm.
- materials such as iron, nickel, neodymium, cobalt, alloys of such metals (e.g., BaFe3C>4, SrFe3C>4, AINiCo) and alloys of rare earth metals, such as NdFeB and CoSm.
- the magnetic elements can have any suitable magnetic flux density.
- the magnetic flux density of the magnetic elements is one factor that will determine the strength of the attraction between the magnetic elements and the magnetically receptive elements. Therefore, the desired magnetic flux density of the magnetic elements will depend, at least in part, on the desired attractive force between the elements (and substrates attached to those elements).
- the magnetic elements exhibit a magnetic flux density of about 50 gauss (G) or more (about 5 millitesla (mT) or more), about 100 G or more (about 10 mT or more), about 150 G or more (about 15 mT or more), or about 200 G or more (about 20 mT or more).
- the magnetic coating preferably comprises a binder and magnetic elements.
- the binder can be any suitable binder that will adhere to the scrim and bind together the magnetic elements.
- Suitable binders include, but are not limited to, urethane binders, acrylic binders, silicone binders, thermoplastic binders, thermoset binders, cements, rubber, and geopolymers.
- the binder preferably remains flexible after curing.
- the binder preferably is selected from the group consisting of urethane binders, acrylic binders, silicone binders, and mixtures thereof.
- the magnetic elements can have any suitable particle size.
- the magnetic elements have a particle size of about 100 microns or less. More preferably, the magnetic elements have a particle size of about 50 microns or less.
- the particle size of the material can affect the magnetic characteristics exhibited by the magnetic elements.
- the magnetic elements can be present in the magnetic coating in any suitable amount.
- the amount of magnetic elements present in the magnetic coating may depend upon several factors, such as the desired strength of the magnetic response and the type of magnetic elements used in the magnetic coating.
- the magnetic elements (which may be one type of element or mixtures of multiple types of elements) generally account for an appreciable percentage of the overall magnetic coating.
- the magnetic elements are present in the magnetic coating in an amount of about 20 wt.% or more, about 30 wt.% or more, about 40 wt.% or more, about 50 wt.% or more, or about 60 wt.% or more of the coating.
- the magnetic elements are present in the magnetic coating in an amount of about 90 wt.% or less. In a more preferred embodiment, the magnetic elements is present in the magnetic coating in an amount of about 20 wt.% to about 90 wt.% (e.g., about 30 wt.% to about 90 wt.%, about 40 wt.% to about 90 wt.%, about 50 wt.% to about 90 wt.%, or about 60 wt.% to about 90 wt.%), about 30 wt.% to about 80 wt.%, about 30 wt.% to about 70 wt.%, or about 40 wt.% to about 60 wt.% of the coating. In another embodiment, the magnetic elements are present in the magnetic coating in an amount of at least about 40 wt. %, more preferably at least about 60 wt. %.
- the magnetic coating can be applied to the scrim in any suitable amount.
- the amount of coating applied to the substrate will depend upon several factors, such as the magnetic strength of the magnetic elements, the amount of magnetic elements in the coating, and the desired magnetic flux density to be exhibited by the coating 120. Due to the amount of coating 120 applied to the scrim 100 and the high content of magnetic elements in the coating, the coating has a high areal density (weight per area). In one embodiment, the magnetic coating has an areal weight of at least about twice that of the areal density of the scrim. In another embodiment, the magnetic coating has an areal weight of at least about 2.5 times that of the areal density of the untreated scrim. In one embodiment, the magnetic coating has an areal weight of at least about 40 g/m 2 .
- the magnetic coating has an areal weight of between about 40 and 1 10 g/m 2 .
- the magnetic coating 120 is applied to the scrim 100 in any suitable manner.
- the coating 120 is applied from an aqueous solution (or mixture or emulsion).
- An aqueous based system is preferred for environmental reasons.
- the coating is solvent based. In one
- the coating 120 is coated by gravure coating, knife coating, curtain coating, printing, and transfer coating.
- the pattern could be in any suitable pattern.
- the pattern may be continuous or discontinuous, regular and repeating or random. “Continuous” in this application means that from one edge of the textile to the other edge there is a path that contains the pattern and that at least some of the pattern areas are connected. Examples of continuous patterns include straight lines and a grid.
- discontinuous in this application means that the areas of the pattern are discontinuous and not touching one another. In a discontinuous pattern, there is no path from one edge of the fabric to the other that contains the pattern. Examples of discontinuous patterns include dots. Regular or repeating patterns mean that the pattern has a repeating structure to it. The pattern may also be a random pattern where there is no repeat to the pattern. In a random pattern, it is preferred that the random pattern is also discontinuous, not
- the pattern may take any patterned form including but not limited to indicia, geometric shapes or patterns, lines (straight and curved), grids, and text.
- the scrim 100 may be coated with additional layers before or after the magnetic coating 120 is applied.
- the scrim 100 is coated with PVC (polyvinyl chloride) before being coated with the magnetic coating 120.
- PVC polyvinyl chloride
- the PVC pre-coating step may provide stability to the loose knit, giving it a structure that may be easily handled without creating any distortion in the arrangement of the warp and weft yarns.
- the PVC coating may also keep the warp yarns tightly bundled and the textured weft yarns fixed in a bloomed, high surface-area form.
- the interior surface of the mold contains iron, nickel, cobalt, an alloys of certain rare earth metals, or mixtures thereof.
- the attraction between the magnetic scrim and mold is strong enough to hold the scrim in place until other materials are introduced into the mold.
