ULTRA-HIGH MOLECULAR WEIGHT POLYETHYLENE FIBERS, KNITS AND ARTICLES CONTAINING THE SAME
The present disclosure relates to knits that can be used to make rip-resistant garments using an ultra-high molecular weight polyethylene (UHMWPE) fiber and a companion fiber such as a stretch fiber or a memory fiber. The UHMWPE fiber includes a monofilament or multiple microfilaments, each of the microfilaments has a denier of 5 or less.
The present disclosure relates to ultra-high molecular weight polyethylene (UHMWPE) fibers, knits and articles of clothing containing the same.
Description of the Related ArtUltra-high molecular weight polyethylene (UHMWPE) fibers, produced from polyethylene resins of ultra-high molecular weight, possess high performance tensile properties such as tenacity, tensile modulus and energy-to-break. The UHMWPE fibers are also extremely hydrophobic and possess numerous other beneficial properties due to said hydrophobicity. The UHMWPE fibers are useful in numerous applications. For example, the UHMWPE fibers may be formed into knitted fabrics for making garments. Examples of specific garments which benefit from the high performance properties of UHMWPE fibers include but are not limited to shoes, socks, pantyhose, tights, leggings, bodysuits, sheer hosiery, pants, shorts, jeans, etc.
Traditional knit fabrics for manufacture of pantyhose or hosieries include Lycra®, Spandex®, often in combination with nylon or polyester. However, these fabrics tend to rip or tear when subjected to frictional forces. It was observed that sheer hosiery products (30 denier and below) made using these fibers are very fragile. They can easily be ripped by hand, foot or hang nail, and are generally considered disposable. Therefore, there remains a need for commercially viable sheer (low denier) elastic knits that are not easy to rip.
In many activities, it is desirable to provide durable garments. Such garments should be flexible, pliable, soft and cut/abrasion resistant. For activities in the sporting arena, the garments also need to be lightweight, and preferably breathable and/or wick and evaporate of perspiration from the athlete. Typically, any improvement in the cut and/or abrasion resistance has usually been at the sacrifice of the other properties, such as comfortableness.
Traditional footwear, whether socks or shoes, suffer from potential issues with retaining and collecting odor, heat, bacteria and microbes, usually via water retention. Numerous footwear advances have been made which attempt to address these issues by coating the garment exterior with waterproof coatings, yet while those coatings tend to prevent water from entering, they also prevent moisture generated by the foot from exiting which leads to moisture and odor build-up within the footwear.
Traditional UHMWPE fibers are produced via UHMWPE powder gel-spinning which is described below. The UHMWPE powders produced today are made using ethylene monomer as their feedstock. Said ethylene is conventionally produced via steam cracking of naphtha (a cut of crude oil), steam cracking of propane or ethane (derived from natural gas or associated gas from fracking and oil production), crude oil to chemicals production, or in certain geographies such as China, from coal via coal to olefins production. All of the above methods of production utilizing fossil fuels as their feedstock, and in the case of crude oil and coal, are some of the heaviest CO2 emitters involved in chemicals production. Even advanced modern “clean” steam crackers produce about 1 ton of CO2 for every ton of ethylene produced. As the world moves towards becoming CO2 neutral the need for more sustainable ethylene and ethylene derivatives production methods increases. Currently there are no commercial sustainable methods being utilized for UHMWPE production.
Therefore, there remains a need for commercially viable knits for making garments and shoes that address the shortcomings of the prior art, as well as methods for preparation and use of sustainable UHMWPE. Embodiments of the present disclosure provide these and related advantages

In another aspect, methods for producing UHMWPE fibers described above are provided.
In some embodiments, the UHMWPE fibers of the present disclosure are prepared from UHMWPE particles by a gel spinning process. The gel spinning process involve steps of a) forming of a UHMWPE solution, b) passing the UHMWPE solution through a spinneret to form a solution fiber including a plurality of solution filaments, c) cooling the solution fiber to form a gel fiber, d) removing the spinning solvent to form an essentially dry, solid fiber, and e) drawing at least one of the solution fiber, the gel fiber and the dry fiber.
The UHMWPE solution is formed by first mixing of UHMWPE powders, UHMWPE resins, or UHMWPE particles, and a spinning solvent. After formation of the liquid mixture of UHMWPE and spinning solvent, the liquid mixture is passed through a heated extruder to get the UHMWPE solution. In some embodiments, the extruder is heated at a temperature between about 100° C. and about 300° C., causing the UHMWPE to swell and dissolve in the spinning solvent. The amount of UHMWPE in the UHMWPE solution is controlled to obtain the UHMWPE fibers of the present disclosure. In some embodiments, the UHMWPE solution contains UHMWPE in an amount between about 0.5% by weight to about 5% by weight, between about 1% by weight to about 2% by weight, between about 1% by weight to about 4% by weight, between about 3% by weight and about 12% by weight, between about 4% by weight to about 10% by weight, between about 5% by weight and about 9% by weight, or between about 6% by weight and about 8% by weight.

In some embodiments, the UHMWPE particles have an average particle size of up to about 1000 micron (μm), up to about 2000 μm, or up to about 5000 μm. In some embodiments, the UHMWPE particles have an average particle size ranging from about 100 μm to about 200 μm. In such an example, up to about, or at least about 90% of the UHMWPE particles have a particle size that is within 40 μm of the average UHMWPE particle size. In other words, up to about, or at least about 90% of the UHMWPE particles have a particle size that is equal to the average particle size plus or minus 40 μm. In another example, about 75% by weight to about 100% by weight of the UHMWPE particles utilized can have a particle size of from about 100 μm to about 400 μm, and preferably about 85% by weight to about 100% by weight of the UHMWPE particles have a particle size of from about 120 μm to about 350 μm. Additionally, the particle size can be distributed in a substantially Gaussian curve of particle sizes centered at about 125 μm to about 200 μm.
The spinning solvent can be any solvent that is essentially non-volatile and solubilizes the UHMWPE powders.

In some embodiments, the UHMWPE solution obtained from step a) is passed through a spinneret containing a plurality of spin-holes to form a solution fiber containing a plurality of solution filaments. The number of spin-holes in the spinneret is determined by the number of microfilaments contained in the UHMWPE fiber.

In some embodiments, the spinneret can have from 10 spin-holes to 300 spin-holes, and the solution fiber can comprise from 10 microfilaments to 300 microfilaments. The spin-holes can have a conical entry, with the cone having an included angle from about 15 degrees to about 75 degrees. Preferably, the included angle is from about 30 degrees to about 60 degrees.

The capillary can have a length to diameter ratio from about 10 to about 100, or from about 15 to about 40. In some other embodiments, the spinning plate can be used to spin multiple UHMWPE fibers at the same time instead of a single UHMWPE fiber with more microfilaments.
Generally, the spinning step b) is carried out at a spinning temperature below the boiling point of the spinning solvent. In some embodiments, the spinning temperature is between about 150° C. and about 250° C. In case of paraffin as solvent, the spinning temperature is below about 220° C., such as between about 130° C. and about 240° C., between about 130° C. and about 230° C., 130° C., between about 130° C. and about 220° C., between about 130° C. and about 210° C., between about 130° C. and about 200° C., between about 130° C. and about 195° C., between about 140° C. and about 200° C., between about 150° C. and about 200° C., between about 160° C. and about 200° C., between about 170° C. and about 200° C., between about 180° C. and about 200° C., or between about 190° C. and about 200° C.
In some embodiments, the solution fiber that is issued from the spinneret can be drawn at a draw ratio of from about 1.1:1 to about 30:1. In some embodiments, drawing of the solution fiber is accomplished by passing the solution fiber continuously through a gaseous zone. In some embodiments, the gaseous zone has a length of from about 0.3 centimeter (cm) to about 10 cm, or from about 0.4 cm to about 5 cm. In some embodiments, the gaseous zone is filled with an inert gas such as nitrogen.
In some embodiments, the solution fiber obtained from the spinning step b) is cooled to a temperature blow the gel point of the UHMWPE to form the gel fiber. In some embodiments, the cooling of the solution fiber is carried out by quenching the solution fiber in a liquid quench bath. The liquid in the liquid quench bath includes, but not limited to, water, ethylene glycol, ethanol, isopropanol, and a water soluble anti-freezer. The temperature of the liquid quench bath is from about −35° C. to about 35° C.
In some embodiments, the gel fiber can be drawn at a draw ratio of from about 1.1:1 to about 30:1. In some embodiments, drawing the gel fiber is accomplished by passing the gel fiber through a set of rollers.
In some embodiments, the spinning solvent in the gel fiber obtained from the cooling step c) is extracted using an extraction solvent to form a dry fiber. The extraction solvent is a low boiling point solvent including, but not limited to, benzene, hexane, pentane, a chlorofluorocarbon such as trichloroethane or trifluoroethane, and a supercritical liquid such as supercritical carbon dioxide (CO2), dinitrogen oxide, ammonia, ethane, or propane. In some embodiments, supercritical CO2 is used to remove the spinning solvent. In some embodiments, after extracting the spinning solvent, the dry fiber can be air dried in the ambient atmosphere.
In some embodiments, the dry fiber can be drawn at a drawing ratio from about 1.1:1 to about 2:1. In some embodiments, drawing of the dry fiber is accomplished by passing the fiber through a daw stand.
Each drawing step described above is independently carried out at a temperature that is preferably chosen to achieve the desired drawing ratio without the occurrence of filament breakage. The overall draw ratio, i.e. the total draw ratio to which the microfilaments are subjected during their entire manufacturing process is at least 20, at least 25, at least 30, or at least 40. The drawing operation helps to increase tensile strength and modulus of the UHMWPE fiber.
In some embodiments, the method of producing UHMWPE fiber further comprises annealing the UHMWPE fiber after the drawing step. In some embodiments, the UHMWPE fiber is annealed by heating the UHMWPE fiber at a temperature ranging from about 40° C. to about 140° C., about 40° C. to about 70° C., about 50° C. to about 80° C., or about 80° C. to about 100° C.
In some embodiments, the UHMWPE fiber is annealed in steam. In some embodiments, the UHMWPE fiber is annealed by heating the UHMWPE fiber in steam.
In some embodiments, the method of producing UHMWPE fiber further comprising twisting the UHMWPE fiber. In some embodiments, the UHMWPE fiber is twisted by air tacking.
In still another aspect, methods of producing UHMWPE used for formation of the UHMWPE fibers described above are provided.
The UHMWPE is obtained through polymerization of ethylene. In some embodiments the ethylene is produced from an ethanol dehydration process. In the ethanol dehydration process, ethanol is converted into ethylene by means of a catalytic reaction at temperatures above 300° C. The dehydration reaction is conducted in the presence of catalysts, such as alumina, silica, silica-alumina, zeolites, and other metallic oxides, being carried out in an adiabatic or isothermal, fluidized or fixed bed reactor.
In some embodiments, ethylene is produced by thermal cracking or steam cracking of naphtha (e.g., oil). In some embodiments, ethylene is produced by thermal cracking or steam cracking of ethane. In some embodiments, ethylene is produced by thermal cracking or steam cracking of propane. In some embodiments, ethylene is produced by the catalytic conversion of coal to syngas which is subsequently converted into ethylene either directly or indirectly via a methanol intermediate (also known as coal to olefins or CTO). In other embodiments, ethylene is obtained from biologically sourced ethanol, known as bioethanol. In some embodiments, the bioethanol is obtained by the fermentation of sugars (including starch and cellulose) derived from renewable biomass sources. The biomass sources include sugarcane, rice, wheat, barley, potato, corn, vegetable oil, or mixtures thereof. In some embodiments, UHMWPE is entirely based on the bioethanol. In other embodiments, ethylene is obtained from methanotrophic bacteria which consume methane (from landfills, biomass, or farm animal emissions) and produce ethylene.
In still another aspect, sustainable UHMWPE fibers can be produced by recycling UHMWPE fibers by re-dissolving them in the gel spinning solution to produce new UHMWPE fibers. In other embodiments, sustainable UHMWPE fibers can be produced by recycling or combining excess UHMWPE powders, UHMWPE resins, or UHMWPE particles.
In still another aspect, methods of producing colored UHMWPE fibers from the UHMWPE fibers described above are provided. The UHMWPE fiber to be dyed can be any color. In some embodiments, the UHMWPE fiber to be dyed has a white color.
In some embodiments, the colored UHMWPE fiber is produced using a non-additive coloring method. Non-additive means that the UHMWPE is colored using a method that does not add to the bulk or the denier of the UHMWPE fiber.
In some embodiments, the colored UHMWPE is produced by contacting the UHMWPE fiber with a dyeing medium for a period of time.
In some embodiments, the dyeing medium comprises a supercritical liquid and a dye. In some embodiments, the supercritical liquid is supercritical carbon oxide, and the dyeing medium comprises at least 50% by weight of carbon oxide. In some embodiments, an amount of the supercritical carbon oxide in the dyeing medium ranges from about 50% by weight to about 80% by weight, from about 60% by weight to about 70% by weight, or from about 50% by weight to about 60% by weight.
In some embodiments, the dye is selected such that the dye is soluble in the supercritical liquid and has a good affinity to the UHMWPE fiber. Good affinity means that the dye, in the supercritical liquid dyeing medium, is well able to penetrate into the UHMWPE fiber, resulting in a high color intensity and high resistance to rubbing and washing. The dye used herein may have black, blue, grey, red, blue, brown, yellow, green, orange, or nude color.
In some embodiments, the dye is mixed with the supercritical liquid and dissolved therein before contact with the UHMWPE fiber to be dyed. In other embodiments, the supercritical liquid and dye are placed into contact with the UHMWPE fiber concurrently. In some embodiments, the mixture of the dye and the supercritical liquid is stirred in order to obtain good homogeneous coloration.
Generally, the dyeing temperature is chosen to ensure good solubility of the dyes in the supercritical liquid and to avoid excessive shrinkage and strength loss of the UHMWPE fiber by the dyeing. In some embodiments, the dyeing temperature is from about 100° C. to about 130° C., from about 110° C. to about 130° C., or from about 120° C. to about 130° C.
The dyeing pressure is chosen in dependence on the supercritical liquid used. For supercritical carbon dioxide, the pressure is at least about 20 MPA (about 2,900 psi), or at least about 25 MPa (about 3,626 psi). The solubility of the dyes is higher at higher pressures. After dyeing, the pressure is reduced at a rate of at most 1.5 MPa per minute or at most 1 MPa per minute. If the pressure is reduced discontinuously, the pressure is reduced in each step by not more than 1.5 MPa or not more than 1 MPa, with the intervals between each step being long enough not to exceed the highest rate of pressure reduction. Too rapid pressure reduction may lead to damage to the UHMWPE fiber.
The dyeing time is chosen so that the color intensity is as high as possible. In some embodiments, the dyeing of the UHMWPE fiber proceeds with the dye at the specified temperature and/or pressure for about 5 minutes to about 250 minutes, for about 30 minutes to about 200 minutes, for about 60 minutes to about 200 minutes, or for about 90 minutes to about 180 minutes. For example, in some embodiments, after contacting the UHMWPE fiber with the supercritical liquid and the dye, the mixture is exposed to about 3600 psi to about 3800 psi of pressure; and/or from about 110° C. to about 130° C.; or from about 90 to about 180 minutes. The pressure may be applied concurrent with, overlapping, or preceding the application of the temperature.
In some embodiments, the dyeing medium further comprises a UV stabilizer for improving the light-fastness of the dye and/or a crosslinking reagent for improving the creep resistance and the oxystability of the UHMWPE fiber.
After the dyeing process, the dyed UHMWPE fiber may have a color contrast of about 90% or greater, about 92% or greater, about 95% or greater. The color contrast is the color of the portion of the UHMWPE fiber that has been dyed on a scale between the color of the portion of the UHMWPE when fully dyed (i.e., 100% contrast) to the pre-dyeing color of the portion of the UHMWPE (i.e., 0% contrast).
In some embodiments, before dyeing the surface of UHMWPE is treated to provide a substantially uniform dye take up.
In some embodiments, after dyeing the UHMWPE fiber is redrawn to enhance the color intensity. In some embodiments, the redrawn operation further enhances the tensile strength and modulus of the UHMWPE fiber.
In some embodiments, after dyeing the UHMWPE fiber is dried at a temperature ranging from about 50° C. to 100° C.
