Definitions

  • the present invention relates to yarns, in particularly yarns used for manufacturing press felts.
  • press felts are made from yarns consisting of monofilaments or twisted monofilaments.
  • spun yarn is used together with the monofilaments, either twisted or wound around the filaments. The purpose of the spun yarn is to densify the felt and create a fast start-up and good nip dewatering.
  • a yarn comprising a plurality of monofilaments twisted together, and a multifilament or a spun yarn wound around the plurality of monofilaments, wherein the multifilament or the spun yarn comprises a bio-based material, a recycled bio-based material or a recycled synthetic material.
  • a method for manufacturing a yarn comprising: providing a plurality of monofilaments and a multifilament or a spun yarn, twisting the plurality of monofilaments together, and simultaneously or afterwards, winding the multifilament or the spun yarn around the plurality of monofilaments, wherein the multifilament or the spun yarn comprises a bio-based material, a recycled bio-based material or a recycled synthetic material.
  • an industrial textile comprising the yarn.
  • the yarn is used in an industrial textile, such as a press felt or a filter fabric.
  • the yarn is used in a paper machine clothing.
  • FIGURE 1 illustrates a yarn in accordance with at least some embodiments of the present invention.
  • bio-based material refers to a material, which is wholly or partly derived from renewable biomass sources, such as plants, trees or animals.
  • the material can be obtained from for example, a sugar containing plant (e.g. corn or sugar cane), plant fat or oil (e.g. castor oil), organic acid (e.g. succinic acid), corn starch, straw, woodchips, sawdust, recycled food waste.
  • a bio-based material can be for example, natural fibre, such as wool, cashmere, cotton, hemp, linen, bamboo or silk.
  • the bio-based material can be obtained by processing from natural biopolymers including polysaccharides (e.g.
  • bio-based material can be for example, polylactic acid (PLA), bio-polyamide (bio-PA), bio-polybutylene succinate (bio-PBS), bio-polyethylene (bio-PE), bio-polyethylene terephthalate (bio-PET), bi-polypropylene (bio-PP), or bio-polyhydroxyalkanoate (bio-PHA).
  • PLA polylactic acid
  • bio-PA bio-polyamide
  • bio-PBS bio-polybutylene succinate
  • bio-PE bio-polyethylene
  • bio-PET bio-polyethylene terephthalate
  • bio-PP bi-polypropylene
  • bio-PHA bio-polyhydroxyalkanoate
  • Cellulose-based materials are bio-based materials manufactured from cellulose, such as cellulose fibres or cellulose derivate, for example, by dissolving pulp, treating pulp mechanically or transforming pulp directly to fibres with water and without any chemicals.
  • the cellulose-based material can be for example, viscose, lyocell, cupro, acetate, modal, or cellulose carbamate.
  • synthetic material refers to synthetic man-made polymers, which are derived from crude oil.
  • the synthetic material can be for example, polyamide (PA), polyester (PET), polyethylene naphthalate (PEN) or polyphenylene sulphide (PPS).
  • the term "overfeed” means that a multifilament yarn or a spun yarn is fed faster than monofilaments in a yarn manufacturing. So, a length of the multifilament or the spun yarn is longer than a length of the monofilament in the yarn.
  • a yarn 100 comprises a plurality of monofilaments 101, 102, 103, 104 twisted together, and a multifilament or a spun yarn 105 wound around the plurality of monofilaments 101, 102, 103, 104.
  • the multifilament or the spun yarn 105 comprises a bio-based material, a recycled bio-based material or a recycled synthetic material. It has surprisingly been found that whole yarn does not have to be made from high quality materials, such as synthetic polyamide, but a part of the yarns, i.e. the multifilament or the spun yarn, can be made from a material, which has a lower strength.
  • the material wears off due to its lower mechanical strength or dissolves due to its chemical composition, it opens the felt structure preventing it from getting too dense.
  • a core comprising monofilaments provides strength for the yarn, and the multifilament or the spun yarn around the core provides a densifying effect that is needed at the start-up of the felt. Therefore, the multifilament or the spun yarn can be made of materials having a lower carbon footprint. Thanks to this, a carbon footprint of the whole yarn and products made from the yarn is reduced. So, the yarn comprising a bio-based material, a recycled bio-based material or a recycled synthetic material provides more sustainable option for generally used yarns manufactured entirely from fossil-based raw materials. Further, using of the recycled material saves energy and material resources. So, the yarn provides longer life time for the press felt by keeping it open longer and a low carbon footprint without sacrificing mechanical properties of the yarn.
  • the bio-based material is a cellulose-based material.
  • Cellulose is natural, biodegradable and recyclable material and causes significantly smaller carbon dioxide emissions than synthetic materials. Therefore, the cellulose-based material is more sustainable choice than fossil-based materials, which are refined and processed from crude oil.
  • the cellulose-based material is selected from the group of viscose, lyocell, cupro, acetate, modal, bamboo and cellulose carbamate.
  • a utilization of wood-based cellulose as the raw material for fibres leads to carbon-neutral cycle, whereby carbon dioxide, which binds to wood, is transported with the product and decomposes back into the atmosphere as a result of burning or biodegradation. Further, production of the cellulose fibres has lower impact on land use and lower emissions than production of many other fibers, such as cotton, allowing more farmland to be used for food production.
  • the bio-based material is selected from the group of polylactic acid (PLA), bio-polyamide 6.10, bio-polyamide 4.10, bio-polyamide 5.10, bio-polyamide 10, bio-polyamide 10.10, bio-polyamide 11, bio-polybutylene succinate (bio-PBS), bio-polyethylene (bio-PE), bio-polyethylene terephthalate (bio-PET), bio-polypropylene (bio-PP), bio-polyhydroxyalkanoate (bio-PHA), wool, cotton, hemp, linen or bamboo.
  • PLA can be manufactured from fermented plant starch, such as from corn, cassava, sugarcane or sugar beet pulp.
  • Bio-polyamides and other bio-polymers are more sustainable choices than fossil-based polyamides, which are refined and processed from crude oil. Natural fibres, such as wool, cotton, hemp, linen and bamboo, are renewable and do not cause microplastic pollution.
  • the bio-based material can be also biodegradable.
  • PLA, bio-PBS, bio-PP and bio-PHA are also biodegradable.
  • these materials are capable of being decomposed by bacteria or other living organisms and thereby avoiding pollution.
  • the recycled bio-based material can be for example, recycled cotton, which is obtained from recycled garments and textiles. Using of the recycled material saves energy and material resources, and thus reduces carbon footprint of the yarn and a final product made of the yarn.
  • the recycled synthetic material can be for example, recycled polyamide (PA), such as polyamide 6, polyamide 6.6, polyamide 6.10, polyamide 4.10, polyamide 10, polyamide 10.10, polyamide 11 or polyamide 12.
  • PA recycled polyamide
  • the plurality of monofilaments 101, 102, 103, 104 comprise polyamide (PA).
  • the polyamide can be bio-based polyamide (bio-PA), synthetic polyamide or recycled polyamide.
  • Bio-based polyamide can be for example, bio-polyamide 6.10, bio-polyamide 4.10, bio-polyamide 5.10, bio-polyamide 10, bio-polyamide 10.10, or bio-polyamide 11.
  • the synthetic polyamide or the recycled polyamide can be for example, polyamide 6, polyamide 6.6, or polyamide 12.
  • the above-mentioned polyamides are excellent choices when mechanical strength and wear resistance is needed.
  • Polyamide 6 fibres are tough, possessing high tensile strength and elasticity.
  • Polyamide 6 has high water absorption.
  • Polyamide 6.6 has a high mechanical strength, a rigidity and a good heat and chemical stability.
  • Polyamide 6.10 high impact resistance, chemical resistance and retention of dimension.
  • Polyamide 11 has lower values of density, flexural and Young's modulus, water absorption, as well as melting and glass transition temperatures than polyamide 6. However, polyamide 11 is seen to have increased elasticity, abrasion resistance and, due to lower water absorption, dimensional stability in the presence of moisture than polyamide 6.
  • the yarn 100 comprises 3-24 monofilaments 101, 102, 103, 104, preferably 3-12 monofilaments 101, 102, 103, 104, more preferably 3-6 monofilaments 101, 102, 103, 104.
  • the yarn 100 can comprise 4, 6, 8 or 9 monofilaments 101, 102, 103, 104.
  • a twist direction of the plurality of monofilaments 101, 102, 103, 104 is the same as a twist direction of the multifilament or the spun yarn 105.
  • the direction of the twist may be to the right (Z twist), or to the left (S twist).
  • a twist direction of the plurality of monofilaments 101, 102, 103, 104 is the opposite as a twist direction of the multifilament or the spun yarn 105.
  • the direction of the twist may be to the right (Z twist), or to the left (S twist).
  • FIGURE 1 illustrates a yarn 100 in accordance with at least some embodiments.
  • the yarn comprises four monofilaments 101, 102, 103, 104 and a multifilament 105 wound around the said monofilaments.
  • a twist direction of the four monofilaments 101, 102, 103, 104 is the same as a twist direction of the multifilament, being a left twist.
  • diameters of the plurality of the monofilaments 101, 102, 103, 104 are 0.1-0.6 mm, preferably 0.2 mm.
  • the diameters of the monofilaments can be selected according to the intended use of the yarn and the number of the monofilaments. For example, when the number of the monofilaments is increased, the diameter of the monofilaments can be decreased.
  • the multifilament or the spun yarn 105 has a linear density of 50-150 dtex.
  • the multifilament or the spun yarn 105 is twisted or non-twisted. Twisting of the multifilament or the spun yarn 105 facilitates its handling and entangles filaments of the multifilament and fibres of the spun yarn together. Further, the twisted multifilament or spun yarn has higher strength and elasticity (i.e. higher stretch). A surface of the twisted multifilament or spun yarn does not wear out so easily. Further, twisting can be used for forming texture to the yarn.
  • the multifilament 105 When the multifilament 105 is twisted, it may be twisted in a first direction. Then, the multifilament 105 may be twisted in a second direction, which is opposite direction than the first direction, around the plurality of monofilaments 101, 102, 103, 104. Twisting of the multifilament provides a good tenacity.
  • the multifilament 105 can be also textured. Texturing can be provided by curling the multifilament.
  • the spun yarn 105 When the spun yarn 105 is used, the spun yarn 105 may be twisted in a first direction. Twisting of the spun yarn 105 holds staple fibres of the spun yarn together. Then, the spun yarn may be twisted in a second direction, which is opposite direction than the first direction, around the plurality of monofilaments 101, 102, 103, 104. This provides a good tenacity.
  • the yarn 100 has an overfeed of the multifilament or the spun yarn 105 of 5-25 %, preferably about 15 %.
  • the overfeed provides a densifying effect that is needed at the start-up of the felt.
  • the cross-section of the monofilaments, the multifilament or the spun yarn 105 can be round, square, rectangular, oval or any other suitable shape.
  • a linear density of the yarn 100 is 200-600 tex.
  • a method for manufacturing a yarn 100 comprises providing a plurality of monofilaments 101, 102, 103, 104 and a multifilament or a spun yarn 105, twisting the plurality of the monofilaments together, and simultaneously or afterwards, winding the multifilament or the spun yarn 105 around the plurality of the monofilaments 101, 102, 103, 104.
  • the multifilament or the spun yarn 105 comprises a bio-based material, a recycled bio-based material or a recycled synthetic material. So, twisting the plurality of the monofilaments together can be done first. After that, the multifilament or the spun yarn 105 can be wound around the plurality of the monofilaments. Alternatively, twisting the plurality of the monofilaments together and winding the multifilament or the spun yarn 105 around the plurality of the monofilaments can be done simultaneously.
  • an industrial textile can comprise the yarn 100 according to an above-mentioned embodiment(s).
  • the yarn provides fast start-up and good nip dewatering for press felts made from it.
  • the yarn comprises the multifilament, there is also less dusting when weaving textiles from the yarn.
  • the bio-based or recycled multifilament or the spun yarn is wearing off, it opens the felt structure thus lengthening its lifetime.
  • the yarn 100 can be used in an industrial textile, such as a press felt or a filter fabric.
  • the industrial textile can be woven or non-woven.
  • the yarn 100 can be used in a paper machine clothing.
