SUSTAINABLE SEQUINS AND PAILLETTES

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims benefit of U.S. Provisional Application No. 63/285,430, filed December 2, 2021, which is hereby incorporated herein by reference in its entirety.

BACKGROUND

[0002] Sequins are frequently utilized in many textile applications to create decorative textures and designs. Conventional sequins typically utilize toxic dyes and pigments among other ecologically damaging plastics, causing a deleterious environmental effect from their widespread use. Once a sequin-containing piece is discarded, the metal or petroleum-based plastics are recalcitrant to degradation and can remain intact in a landfill for thousands of years. Moreover, current sequin products often contain harmful additives, which can leach microplastics and toxic chemicals into the water supply.

[0003] Beyond the substantial environmental impact, existing sequins have numerous quality- related limitations, such as flimsiness, making the sequin susceptible to breakage. Additionally, current methods of making sequins require expensive and complex equipment and further generate a large amount of wasted plastic material. Numerous embodiments of the present disclosure address these and other limitations.

SUMMARY

[0004] In some embodiments, the present disclosure pertains to biodegradable sequins that include: a polymeric component; and a decorative component combined with the polymeric component. In some embodiments, the biodegradable sequin has a dimmed appearance. In some embodiments, the biodegradable sequin is in the form of a paillette, button, zipper, trimming, or combinations thereof. In some embodiments, the biodegradable sequin has a thickness of at least about 0.3 mm. Atorney Docket No. 10046-462W01

[0005] Additional embodiments of the present disclosure pertain to methods of making the biodegradable sequins of the present disclosure. In some embodiments, such methods include: mixing a polymeric component with a decorative component to form a mixture; and applying the mixture onto a surface to form the biodegradable sequin.

[0025] In some embodiments, the present disclosure pertains to biodegradable sequins. As used herein, the term “biodegradable” refers to a material (e.g., a sequin) in which a significant portion of the components of the material (e.g., at least 25%, at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 75%, at least 80%, or at least 90% by mass) degrade to base molecules such as carbon dioxide, methane and/or water by reactions and the action of appropriate microorganisms within a reasonable limited time frame (e.g., 5 years, 3 years, 2, years, 1 year, etc.) under “ideal” biodegradation conditions (e.g., anaerobic digester, industrial compost, or the like), e.g., such as conditions under various ASTM biodegradability tests (e.g., ASTM D-5511-18, D-5526-18, D5338-15(2021), or D-6691-17, each of which is hereby incorporated by reference in its entirety).

[0026] In some embodiments, the biodegradable sequins include a polymeric component and a decorative component. In some embodiments, the decorative component is combined with the polymeric component. In some embodiments, the biodegradable sequin has a dimmed appearance.

[0027] Additional embodiments of the present disclosure pertain to methods of making sequins. In some embodiments illustrated in FIG. 1, the methods of the present disclosure include: mixing a polymeric component with a biodegradable decorative component to form a mixture (step 10); and applying the mixture onto a surface (step 12) to form the sequin (step 14). In some embodiments, the methods of the present disclosure also include a step of cutting the sequin into a desired shape (step 16).

[0028] As set forth in more detail herein, the sequins of the present disclosure can include numerous polymeric components, decorative components, dimmed appearances, and forms. Additionally, various mixing, applying and cutting steps may be utilized to make the sequins of the present disclosure.

Polymeric Components

[0029] Polymeric components generally refer to sequin materials that include one or more polymers. The sequins of the present disclosure can include numerous types of polymers. For instance, in some embodiments, the polymers include, without limitation, thermoplastic polymers, polyesters, polylactic acid (PLA), polybenzimidazole, polycarbonate, polyether sulfone, polyoxymethylene, polyether ether ketone, polyetherimide, polyethylene, polyphenylene oxide, polyphenylene sulfide, polypropylene, polystyrene, polyvinyl chloride, polyvinylidene fluoride, polytetrafluoroethylene (Teflon), and combinations thereof.

[0030] In various embodiments, the polymeric component includes a biodegradable polymer. In some embodiments, the biodegradable polymer can meet the pass levels for readily and ultimate biodegradability according to the OECD Guideline for Testing of Chemicals, Method 301 B: CO2 Evolution (Modified Sturm Test). In some examples, the polymeric component is a biodegradable thermoplastic polymer, such as a biodegradable polyester. Example biodegradable thermoplastic polymers include, for example, polylactic acid (PLA); polycaprolactone (PCL); polybutylene succinate (PBS); polybutylene adipate terephthalate (PBAT); polygly colic acid (PGA); polyhydroxyalkanoates such as poly-3 -hydroxybutyrate (P3HB), poly-4-hydroxybutyrate (P4HB), poly-3 -hydroxy valerate (PHV), and copolymers thereof such as poly(3- hydroxybutyrate-co-3-hydroxyvalerate) (PHBV); copolymers thereof (e.g., poly(lactic-co- glycolic acid) (PLGA), and blends thereof. In some embodiments, the polymeric component can comprise a polyester, such as polylactic acid, polygly colic acid, or a copolymer thereof. In some embodiments, the polymeric component can comprise polylactic acid (PLA).

Decorative Components

[0031] The sequins of the present disclosure can include numerous types of decorative components. In some embodiments, the decorative component is an environmentally-friendly and/or biodegradable material. As used herein, reference to a “biodegradable decorative component” and the like refers to a non-toxic additive capable of degrading over time by water and/or enzymes found in nature, without harming the environment. For instance, in some embodiments, the decorative components include, without limitation, biodegradable glitter (e.g., mica glitter), biodegradable pigments, and combinations thereof.

[0032] In some embodiments, the decorative components include biodegradable pigments. As used herein, the term “biodegradable pigment” and the like refers to biodegradable or bioderived materials added to provide a colorant effect. The biodegradable pigment can be a single colorant or a combination of different biodegradable colorants. In various examples, the decorative component can include a natural colorant, derivative thereof, or a combination thereof. A natural colorant is one that can be obtained or derived from plants (e.g., roots, berries, barks, leaves, woods, etc.), animals, insects, bacteria, protozoa, or fungus, or minerals. Nonlimiting examples of such natural colorants include natural indigo blue, chlorophyll, and/or natural turmeric. For example, the biodegradable pigments can include, without limitation, pigments derived from agricultural waste, pigments derived from compostable materials, pigments derived from algae, pigments derived from hemp, pigments derived from coffee, pigments derived from spices, and combinations thereof.

Biodegradable Sequins [0033] The biodegradable sequins of the present disclosure can have various attributes. For instance, in some embodiments, the biodegradable sequins of the present disclosure are industrially compostable. As used herein, the term “compostable” refer to biodegradation into soil conditioning material (i.e., compost). In order for a plastic sequin to be labeled as commercially or industrially compostable it should be broken down by biological treatment at a commercial or industrial composting facility in 180 days or less. Composting utilizes microorganisms, agitation, heat, and humidity to yield carbon dioxide, water, inorganic compounds, and biomass that is similar in characteristic to the rest of the finished compost product. Decomposition of the biodegradable sequin should occur at a rate similar to the other elements of the material being composted and leave no toxic residue that would adversely impact the ability of the finished compost to support plant growth. ASTM Standards D6400-21 and D6868-21 outline the specifications that must be met in order to label a plastic as industrially “compostable.” As an example, poly lactic acid (PLA) is both biodegradable and industrially compostable. Furthermore, biodegradable polymers such as polylactic acid (PLA) do not harm the environment while they are degrading and after they have degraded completely.

[0034] The biodegradable materials of the present disclosure can be derived from various sources. For instance, in some embodiments, the biodegradable materials of the present disclosure are derived from agricultural waste. In some embodiments, the biodegradable component is Polylactic Acid (PLA) and is derived from agricultural waste. For example, polylactic acid (PLA) can be obtained from various natural renewable resource material including corn, plant starches (e.g., potatoes), and canes (e.g., sugar cane).

Mixing of Polymeric and Decorative Components

[0035] Various methods may be utilized to mix polymeric and decorative components in order to form mixtures. For instance, in some embodiments, the mixing includes stirring. In some embodiments, the mixing includes the utilization of three-dimensional (3-D) printers.

[0036] The polymeric components of the present disclosure can be mixed with decorative components in various forms. For instance, in some embodiments, the polymeric component includes molten polymer. As such, in some embodiments, the methods of the present disclosure also include a step of melting the polymer.

[0037] In some embodiments, the polymeric component includes monomeric units of a polymer. As such, in some embodiments, the methods of the present disclosure also include a step of curing the monomeric units to form the polymer.

Applying Mixtures to Surfaces

[0038] Various methods may also be utilized to apply mixtures of polymeric and biodegradable decorative onto surfaces. For instance, in some embodiments, the applying occurs by spraying the mixtures onto surfaces. In some embodiments, the applying occurs by pressing the mixtures onto surfaces. In some embodiments, the applying occurs by applying pressure onto surfaces.

[0039] In some embodiments, the applying occurs through the utilization of a 3-D printer. In some embodiments, the sequin formation methods of the present disclosure occur through the utilization of a 3-D printer. In some embodiments, the applying results in the formation of flat sheets of sequins on a surface.

[0040] The mixtures of the present disclosure may be applied to various surfaces. For instance, in some embodiments, the surface is a flat surface. In some embodiments, the surface is in the form of a mold. In some embodiments the paillettes are formed through 3D printing.

Cutting of Sequins

[0041] In some embodiments, the methods of the present also include a step of cutting the flat sheet or formed sequins into a desired shape. In some embodiments, the cutting occurs by laser cutting.

Uneven Surfaces

[0051] In some embodiments, the sequins of the present disclosure may have an uneven surface. In some embodiments, the uneven surfaces are defined by peaks, basins, and combinations thereof.

[0052] In some examples, the biodegradable sequins include a textured surface characterized by an average surface roughness (Ra). The “average surface roughness” refers to an arithmetic average of absolute values of differences between the average surface height and each surface height over a representative planar section of the sequin. In some embodiments, the average surface roughness of the sequin of 1 pm or more, such as 2 pm or more, 3 pm or more, 4 pm or more, 5 pm or more, 6 pm or more, 7 pm or more, 8 pm or more, 9 pm or more, or 10 pm or more.

[0053] In some embodiments, the biodegradable sequins of the present disclosure have a matte finish. In some embodiments, the biodegradable sequins of the present disclosure have a texture and an uneven color that conveys the natural aesthetic look.

Advantages and Applications

[0054] The sequins and methods of the present disclosure provide numerous advantages and applications. For instance, unlike pre-existing sequins, which are typically made out of non- biodegradable plastics, the sequins of the present disclosure can be composted, thereby providing a sustainable and biodegradable option. Moreover, unlike pre-existing sequins, which have thin and have flimsy qualities, the sequins of the present disclosure provide more stable structures along with novel looks, feels, and textures.

[0055] The methods of the present disclosure also provide various advantages. For instance, in some embodiments, the methods of the present disclosure provide efficient methods of making sequins without generating substantial waste. For instance, scraps created from laser cutouts can be heated, pressed down and reused to create a zero waste product.

[0056] In a specific embodiment, biodegradable sequins can be made by mixing together polylactic acid (PLA) and natural non-toxic pigments. Like the core materials, these pigments do not cause harm to the environment during the process of or after degradation, and remain inert once the degradation has been completed. This pigmented polylactic acid (PLA) can then be used in 3D printing sequins by way of extrusion while at the same time minimizing wasted product.

[0057] As such, the methods and sequins of the present disclosure can find numerous applications. For instance, in some embodiments, the methods of the present disclosure can be utilized to make sequins for numerous applications, such as use as buttons, zipper pulls and other trimmings.

Additional Embodiments

[0058] Reference will now be made to more specific embodiments of the present disclosure and experimental results that provide support for such embodiments. However, Applicant notes that the disclosure below is for illustrative purposes only and is not intended to limit the scope of the claimed subject matter in any way.

Example 1. Sustainable Sequins and Paillettes

[0059] This Example illustrates the facile fabrication of sustainable sequins and paillettes. Applicant purchased polylactic acid (PLA) clear pellets, melted them down, and mixed them with biodegradable glitters and pigments derived from algae, hemp, and coffee to create a nontoxic color. In the case of the pigmented polylactic acid (PLA), the pigment degrades simultaneously with the actual product. During the process of degradation and once degraded, it does not have any negative environmental impact. Thereafter, Applicant poured the mixture onto a Teflon sheet and then pressed the material using a heat setting and 6000 pounds of pressure. Next, Applicant laser cut the sheets onto custom designed shapes. [0060] Applicant purchased biodegradable PLA infused with color from manufactures in the form of spools. Applicant cut the spools up into pellets, pressed them into a sheet and laser cut custom designed shapes. Applicant used a 3D printer to print out the paillettes and sequins directly onto the bed using sustainable PLA options.

[0061] Applicant created a novel design for the product using a 3D Fusion 360 CAD software, then converted the file into geode. From there, the file was uploaded to a 3D printer that was set up with a spool of one of the coffee or hemp pigmented polylactic acid (PLA). The printer then printed only the desired product, leaving no waste behind. These products have a rougher texture on the surface than the ones that had been laser cut due to the printing process. As opposed to a uniform surface, the 3D printer forms products by extruding the aforementioned polylactic acid (PLA) into concentric circles.

Example 1.1. Thickness Measurements

[0062] As summarized in Table 1 and illustrated in FIGS. 2-11, Applicant fabricated various types of sequins and paillettes through the aforementioned processes. Average sequin and paillette thicknesses are about 0.1 millimeters. However, Applicant’s sequins and paillettes had thicknesses ranging from 0.3-0.8 millimeters.

[0063] For instance, as depicted in FIG. 3, one of Applicant’s sequins and paillettes showed a thickness of 0.5 mm. Similarly, the images in FIGS. 4A-B show an example of an algae paillette (FIG. 4A) made from biomaterials and a standard sequin (FIG. 4B) made with plastic material. The thickness in the paillette in FIG. 4A measures 0.5 mm and the thickness of the paillette in FIG. 4B measures 0.1 mm in thickness.

Table 1. Types of fabricated sequins and paillettes.

Example 1.2. Texture Measurements

[0064] The textures of the surfaces of Applicant’s sequins and paillettes are significantly less smooth than the textures of the surfaces of commercial sequins. For instance, scanning electron microscope (SEM) images of Applicant’s green algae paillette (FIG. 5A) and a commercial green paillette (FIG. 5B) illustrate that Applicant’s sequins and paillettes have rougher surfaces.

Example 1.3. Brightness Measurements

[0065] Applicant’s sequins and paillettes are less bright than standard paillettes and sequins in the market. For instance, as illustrated in FIGS. 6A-6B, the standard green and blue paillettes (FIG. 6A) show a significant difference in measurement of brightness compared to Applicant’s green algae PLA paillettes (FIG. 6B). Similarly, Applicant’s paillettes made from coffee PLA (FIG. 7), hemp PLA (FIG. 8), and biodegradable green glitter (FIGS. 9-11).

[0066] Table 2 shows the results from a brightness test of Applicant’s algae green paillettes against a commercial standard paillette. Spectrophotometers, which measure the amount of light reflecting from a surface, were utilized in the brightness tests.

Table 2. Datacolor 200: Brightness test table.

[0067] The lightness (reflectance) of Applicant’s algae green paillettes is less than that of the commercial paillette (CIE L=89.21). Applicant’s algae green paillette lightness CIE L is 36.75 (calculated as 89.21-(52.44+52.09+52.86)/3 = 36.75). The algae sample color is significantly different from that of the commercial paillette, which is 87.34 (CIE DE is (87.10+86.78+88.75)/3 = 87.34).

[0068] Based on the brightness test results, the commercial paillette brightness level was 89.21 CIE L while Applicant’s algae paillette brightness level was 36.75 CIE L. Based on the L value representing lightness, the DE shows that the algae prototypes are significantly darker and have less shine than the commercial paillette sample. The deviation is extremely out of tolerance, concluding that the Applicant’s paillettes and sequins are quantifiably darker with less brightness than the commercial paillettes.

[0069] As measured in the Datacolor 200 Spectrophotometer (Table 2), the brightness of the algae paillettes was tested against the standard commercial paillette and repeated with three samples. The results concluded that the algae samples failed in comparison to the commercial paillettes with a significant difference in brightness measurement. This quantifiable result concludes that the algae finish does not have the same level of color brightness as a commercial paillette. The matte appearance offers a new aesthetic selection to the current options in the market. [0070] Additionally, Applicant performed a comparative gloss test by utilizing an AMSTAT Digital LCD Gloss Meter Tester. Applicant observed that the glossiness level of a commercial paillette was 368 Gu (gloss units) while the glossiness level of Applicant’s algae paillette was 29.2 Gu (gloss units).

Example 1.4. Biodegradability Measurements

[0071] In order to evaluate the biodegradability of Applicant’s paillettes under composting conditions, a boiling test was performed on three commercial sequin paillettes and three of Applicant’s algae sequin paillettes. The weight of each paillette was taken of each sample in both dry and wet conditions prior to the study and then again at 10-minute, 20-minute, 30-minute and 60-minute marks after leaving the samples in a boiling pot full of water. The final weight at the 60-minute mark concluded that the algae paillettes biodegraded .01 gn more than the commercial paillettes. The results are summarized in Table 3.
