Description

TITLE OF THE INVENTION:A Textile Yam / fiber Carrier / tube with High Compressive Strength & Sustainable Hybrid Technology or MethodFIELD OF THE INVENTION:

[0001] This Hybrid yarn carrier / tube and technology or method is invented mainly for the textile industry for carrying, winding or reeling a yarn / fiber on a sustainable high compressive tube which can be reused many times to provide a cost-effective reusable carrier solution.BACKGROUND OF THE INVENTION:

[0002] Sustainable, environment friendly yet cost effective solutions are very much necessary in every field in order to prevent exhaustive use of the natural resources and global warming. Moreover, across the globe, every industry is trying to reduce the energy consumption and in turn saving the cost of goods being manufactured so that they can withstand the demand keeping global competition in account. This surges an immediate need for new invention in every field.

[0003] Now days, one of the most common fast moving commodity items is Textile fiber / yarn of various types catering the products ranging from: a. Clothing and Clothing accessories- Shirt, Pants, Jackets, Belts, Dresses, Saaris, Innerwear, Socks, Handkerchief etc., b. Sports- Shoes and accessories, sports ware, sports equipment, c. Automotive- vehicle Interiors, Auto Accessories and ancillaries like batteries, d. Home Furnishing- Rugs Carpet, Mat, furniture like sofa chairs etc., Bed sheets, e. Technical textiles- Defense, Aviation, Aerospace, Geo-grids, Construction etc. f. Fishing & Farming- Fishing net, Greenhouse farms, Hydroponics g. And almost everywhere.

[0004] Every application or end use product mentioned above requires yarn / fiber whether it may be natural or synthetic. In other word yarn / fiber is the genesis of all of these products and applications.

[0005] Globally, Textile industry is growing rapidly as the demand for textile related goods is increasing enormously. In addition to the increase in demand, lifestyle and fast fashion and one time use trends are multiplying the demand abruptly. Still the entire demand is not fulfilled and still there exists a segment of population across the globe including developed countries which can’t even afford basic necessary clothing and shelters just because it is still not cheap enough that they can afford it. And the irony is day by day it is getting costlier and costlier because of limited natural resources and abusive utilization of them. There are several factors behind the high cost of this textile goods and textile articles. Since we have limited natural resources, one of the major reasons of high manufacturing cost in textile industry is yarn / fiber carriers or packaging on which the fiber / yam is wound or reeled (Yarn / fiber carrier means the carrier / tube / coil / cone / spool / bobbin / roll- whether solid or perforated / straight or tapered or it is a medium or a packaging material on which the yarn / fiber is wound or reeled or coned and can be used to carry or store or transport the yarn / fiber for further process) because the most commonly used cost effective medium to make yarn / fiber carrier so far is made from Paper. Paper is the core product in textile tubes, cheese, cones, roll, pipes etc. which are mostly used as yarn / fiber carrier. This in turn requires lots of wood or other materials from which the Paper is produced and of course exhaustive use of them will affect the global environment.

[0006] The present invention is for nature lovers and keen to provide the world a sustainable and cost-effective solution against the conventional costly and energy consuming solutions. Driven by the idea to provide an alternate solution to enormous use of Paper in packaging and reeling of yarn / fiber, the invention started developing yam carriers as an alternative solution to Paper carriers.

[0007] One of the major segments in textile industry where majorly Paper tubes were used as a carrier and it is still being used because of complex process parameters, because of extrusion machine’s design and high precision requirements is the spinning industry which makes lump of fibers or polymers into a continuousfilament yarn using extrusion process. Ideally these spinners are the origin or the root source or core raw material supplier for all further Yam / fiber processors, weavers, knitters etc. as they convert a lump of fibers or polymers into a continuous filament yam / fiber which is further used as raw material for all the applications like twisting, weaving, dyeing, knitting, crocheting, braiding, sewing etc. and finally all the applications mentioned above. Globally there were many trials and attempts were made to shift this industry to use Plastic carrier / tubes instead of Paper. The present invention also developed a Plastic carrier version for them like for other textile processes and industries and used to approach these spinners to use it and to shift this industry from Paper carrier consumer to Plastic ones. Many of these industry technicians and MNC companies which were highly experienced and qualified in this textile field, also MNCs from Plastic industry, developed an alternate carrier for these spinners using a variety of Plastic material and also combinations of the Plastic materials and started using them. But they were very expensive, proprietary and customized solutions for self- consumption and also specific to their requirement and not keeping in mind the entire industry. So, this industry was still searching for a standard solution which could cater all.

[0008] Meanwhile, majority of this industry continued using the Paper tube as their main yam / fiber carrier / tube and the reasons for the same were as below

[0009] There were few factors why Paper carrier / tubes were and is still being used in this spinning industry as well as other textile process industry are as followed

[0010] Advantages of using Paper carrier / tubes: - a. They are cheap compared to other alternate materials available for carriers. b. Considering applications where yam / fiber is sold directly to customers or processors for further processing as a raw material, Paper carrier / tube is cheaper packaging material as a one time packaging material compared to other material. c. Paper carrier could also be reused by making it high compressive strength using more layers of Paper. d. Paper is a soft and flexible material compared to other hard and rigid materials like Plastics. So, using it on machines is easy compared to Plastic.

[0011] No doubt, spinners did make these Paper carriers / tubes on which thiscontinuous filament yarn / fiber is wound or reeled as reusable as possible by providing it more compressive strength by rolling more Paper layers into it and they made these Paper tubes have more compressive strength in textile spinning process. As a result, these tubes were reused but not for longer reuse as Paper has its limitations.

[0012] Limitations of Paper carrier / tubes: - a. Paper carrier / tubes could be damaged very easily in transporting and handling, b. Also, the spinners and other textile processors were focused to have maximum package size i.e. the quantity of yarn / fiber wound or reeled on it was so much that it could carry the maximum yarn / fiber on the carrier in order to reduce the packaging cost and also to have maximum efficiency for further applications. This was making the yarn / fiber spool or package weight go up to 15 kgs / package or sometimes even more. This required more compressive strength and to make that they required more layers of Paper which in turn was costly. c. Minor finishing error or rough surface or torn Paper on the Paper tube or on tube edges were making unwinding of the fiber / yarn difficult and in turn breaking the fiber / yarn during the further process resulting in loss of efficiency. d. One of the major drawbacks that Paper carrier had was its susceptibility to moisture / humidity. They lose their strength in monsoon or in humid weather and can be easily damaged.

[0013] Spinning industry was bearing huge losses in terms of yarn / fiber wastages, in handling, in storage and warehousing in humid conditions, inefficient reutilization etc.

[0014] As a result, Plastic carriers started being used in the spinning industry as well but mostly for self-consumption which was thought to solve the above problems as Plastic carrier can provide way more advantages over Paper carrier / tube which are as followed.

[0015] Advantages of Plastic carrier over Paper carrier: - a. High Compressive strength than Paper,b. It can withstand the pressure during transportation and handling, c. Finishing can be derived to optimum levels using lots of material combinations and tools and technology for different processes and applications. d. Also they are not susceptible to humidity, moisture or monsoon weather. e. It could be reused many more times than Paper tubes because of high strength and rigidity thereby making them more cost effective and long lasting

[0016] But these Plastic carriers also had few limitations which are as followed

[0017] Limitations of Plastic carrier: - a. They are costly compared to Paper carriers. Spinners who directly sell their products i.e. who sell, spun yam / fiber to their customers after spinning i.e. to yarn / fiber processors, can’t afford to provide Plastic carriers to their customers due to high material cost compared to Paper tube carriers. As they can’t reuse these Plastic carriers again and they can’t even recollect it from the customers as they are in volumes and collecting cost of the same or logistic cost of the recollection goes high and it also a tedious process when it comes to recollection from number of customers from different geographic locations and especially from Abroad. b. Further, the machines used for spinning are very costly, complex in design and require lots of high precision for high speed winding the fiber / yam and the process of continuous polymerization or in any spinning process they require very high precision carriers which can support Auto Doffing i.e. yarn / fiber wound packages or spools should be easily and automatically taken out of machines and new empty carriers / tubes can be loaded automatically without human intervention for high efficiency with minimum losses. Plastic carriers are way more hard and rigid (less flexible) because of Plastic properties compared to Paper tubes. And these sometimes make Auto Doffing fail while taking the yarn / fiber wound package out of the machine as Plastic tubes / carrier are very hard they sometime grips the take up of the machine very hard from where the final output is derived because the yarn / fiber which is wound on the carrier weighs 10-15 kgs and it builds the tension on carrier / tube because of high speed ,high tension winding andthereby compressing the Plastic carrier / tube with pressure and this make them stick to the take up drums tightly. So, this sometimes requires manual intervention to take the package out and this fails the Auto doffing resulting in efficiency losses. Sometimes it also damages the machine parts. Similarly, because of Plastic’s rigidity, sometimes while loading empty Plastic tubes using machine’s auto doffing technology also fails if fractions dimensional errors or changes are there piece to piece. c. Also, few Plastic materials used for yarn / tube carriers have the tendency to shrink naturally because of the relaxation process and also some of them tend to elongate over a period of time after multiple times due to tension applied to it or heavy yam / fiber wound on it. This also creates a challenge for Auto Doffing failure after multiple usage of the same Plastic carrier

[0018] So, considering above advantages and disadvantages of both materials i.e. Paper and Plastic yam / fiber carrier / tube there was a need which could last long, can be reused multiple times, cost effective and also machine technology friendly and adaptive with high precision requirements and specifications.

[0019] This created an urge to provide the Hybrid solution which can balance the advantages of both materials, a. which is flexible enough yet have high compressive strength which is double the current compressive strength which can be reutilized like Plastics i.e. more than the conventional solutions of Paper carriers / tubes b. can withstand any weather condition c. Reusable, cost effective d. Sustainable and adaptive to complexity of the process and machines e. Can be a universally accepted across the globe as standard solution

[0020] As a result, the present invention is a Hybrid technology or method cum Hybrid carrier / tube which comprises all of these above features which is nothing but the carrier / tube and a technology or method which includes combinations and advantages of both Paper and Plastic / Metal materials. And this technology or method can be utilized in all kinds of yam carrier / tube for all kinds of textile industryOBJECTS OF THE INVENTION:

[0021] The main objective of the invention is Sustainability: - One of the main objects of the aforesaid invention is to provide the textile industry a product and the technology or method for yarn / fiber carrier which will be sustainable consuming less natural resources and can be recycled easily yet it solves the industries need for yam / fiber carrier / tube.

[0022] The another objective of the invention is Reusable & Cost Effective:- In addition to the sustainability, the product developed using this new innovative Hybrid technology or method should be reusable i.e. Cost effective which in turn saves the cost of goods sold by reducing the packaging cost i.e. by reducing the number of yarn / fiber- carrier / tube used (during the manufacturing process cycle) by making carrier / tubes long lasting by increasing their compressive strength so that they can be reutilized for the same process more number of times. This will finally reduce the cost of goods sold and make it more affordable to the processor or consumer.

[0023] Still another objective of the invention is Weather proof: - Moreover the product or technology or method must not be susceptible to weather conditions like moisture, humidity or rainy season so that it can withstand any weather in warehousing or storage, during transportation or handling and hold the yarn / fiber wound or reeled on it for longer period without incurring transportation, storage and handling damage losses.

[0024] Yet another of the present inventions is Standardization & Universally Adoptable.

[0025] Further objective of the invention is that the invented technology or method must be adopted and accepted universally irrespective of machine’s design, weather conditions, geographical region, processing technology etc. Also, the technology or method and the products can be standardized and can be technically & commercially accepted in the entire textile industry across the globe.SUMMARY OF THE INVENTION:

[0026] This invention provides the textile industry both- a universal product and a Hybrid technology or method solution for yarn / fiber carrier that can be standardized and can be commercially and technically easily adopted in the entire textile industry throughout the world irrespective of the weather conditions, geographical regions, machines or the textile process which saves the consumption of natural resources, can be recycled, gives high compressive strength making the product durable, long lasting and reusable and thereby making it more cost effective that enables textile yarn / fiber manufacturers, processors or consumer to save the cost of goods being manufactured, processed or consumed and ultimately make it more affordable to the end user or consumer.BRIEF DESCRIPTION OF THE DRAWINGS:The invention shall be described in further detail below under reference to the accompanying drawings, in which:

[0043] Brief of Invention need a. As explained, the textile yarn / fiber spinning industry which makes continuous filament yarn by using extrusion process are the major raw material supplier and they have been seeking the carrier solution which has the advantages of both the raw materials being used for the carrier i.e. of Paper which is cheaper and has the flexibility to adopt machine’s design and conditions with less wear and tear i.e. Paper carriers are less rigid compare to Plastic as well as the advantages of Plastic or metal i.e. which can provide higher compressive strength, also it can withstand any weather condition, it must be used many more times than the conventional Paper carrier so that it can save the packaging cost and in turn the cost of goods sold. b. Although proprietary carriers were developed by the industries, they were either full Paper carriers or complete Plastic carriers and also, they were specific to the particular industry and particular machines making them not accepted universally. So, both of the carriers were missing the practical requirement of the industry. c. Therefore, there is a huge gap and demand for the textile yam / fiber spinning and other yarn processing industry. To resolve the same I invented a Hybrid carrier and a technology or method which combines Paper and Plastic Material or Paper and Metal Material both together in a single carrier which provides the advantage of both the materials i.e. Paper and Plastic or Paper and Metal materials. Besides inventing a Hybrid carrier i.e., a carrier whichis made using combination of both Paper and Plastic material or a combination of Paper and Metal material, I also invented a technology or a method which can be used by all kinds of textile yarn / fiber manufacturers and processors at different stages of the textile yam / fiber manufacturing and processing like Spinning, Texturing, Cabling, Twisting, Plying, Winding, Rewinding, Splitting, Assembling, Reeling, Coning, Threading, Dyeing, Conditioning, Heat-setting, Braiding and all other textile yarn / fiber manufacturing and yarn / fiber processing where yarn / fiber carriers or tubes are used

[0044] Invention detail a. Mainly the Invention is a Hybrid carrier which is nothing but a carrier made from the combination of both Paper and Plastic material or a combination of both Paper and Metal material and an invention of a technology or a method which can be applied to all textile yarn / fiber carrier (Yarn / fiber carrier means the carrier / tube / coil / cone / spool / bobbin / roll- whether solid or perforated / straight or tapered or it is a medium or a packaging material on which the yarn / fiber is wound or reeled or coned and can be used to carry or store or transport the yarn / fiber for further process) used in various textile yarn / fiber manufacturing & yarn / fiber processing like Spinning, Texturing, Cabling, Twisting, Plying, Winding, Rewinding, Splitting, Assembling, Reeling, Coning, Threading, Dyeing, Conditioning, Heat-setting, Braiding and all other textile yarn / fiber manufacturing and yarn / fiber processing where yam / fiber carriers or tubes are used in order to have the advantages of both the materials i.e. Plastic / Metal and Paper carrier and get the best compression strength, reusability, sustainability, cost effectiveness, and can be standardized. So the Hybrid carrier and a technology or method has 3 important components and combinations. b. Let us consider the example of Hybrid cylindrical tube for textile Yarn Spinner who makes POY, FDY, IDY & various types of yam etc. i. Open end Inner Paper Core ii. Collar type / without collar type - Two Piece or single piece Plastic or Metal intermediate Supporting core iii. Open end Outer Paper Corec. The importance and arrangement of these 3 components are as followed

[0045] Open end Inner Paper Core i. As we know that Plastic is rigid material compared to Paper and that’s why it provides more strength than Paper but this sometimes becomes it’s disadvantage too because whenever the process of extrusion of yarn their is a machine part called “chuck”, also called “ winder chuck” is designed specially for gripping the Paper tube / carrier and the important part is that the gripper is moving while load the tube on it and also moving while onload the tubes, so Plastic surface is not suitable for it and that's why only making Plastic carrier was not practical for the high-speed precision machines especially in the extrusion process. So, we needed a material which could be less rigid or less hard compared to Plastic which is nothing but Paper (which industry is already using) which will be in direct contact with machine parts or take up. So, we used Paper core as an innermost component of the Hybrid carrier so that the machine contact point or take up gripping material will not be as rigid as Plastic and will not damage the contact parts or assembly of the machine.

[0046] Collar type / without Collar type- Two-piece or Single-piece Plastic Intermediate supporting core or Two-piece or Single-piece Metal Intermediate supporting core a. This is the most crucial and critical component of the entire Hybrid carrier and a technology or method. It is also called the strength builder and it is the backbone of the entire Hybrid carrier and the entire technology or method. This component is designed using different permutations and combinations of Plastic(polymer) or Plastic polymer with metal or only metal (polymer option like PP / ABS / NYLON / POLYCARBONATE / SAN etc. ) depending upon the denier of the yarn and type of yam being wound on it, output package weight to be derived, applications and further textile process to be carried out on it, unwinding patterns etc.b. Importantly this Plastic or Plastic combination metal component is designed in 2 pieces so that it can easily fit between the outer and inner Paper core. It is mainly sandwiched between both outer and inner Paper core and acts as a supporter and separator at the same time limiting the outer and inner core from expanding and contracting due to heavy yarn tension or multiple time reuse. c. The reason why it is designed in 2 pieces is because it has outer collar arrangement and this collar is very crucial element which is a smooth Plastic or metal coated surface and is used for smooth and complete yam unwinding process without yarn breakages when bottom yarn unwinding takes place at high speed. This smooth collar will completely cover the outer Paper core’s rough cylindrical edges and those collars will substitute the need of unwinding caps as well. Many times due to the damaged, rough or uneven Paper edges, complete yarn unwinding gets difficult and yarn gets broken during the further high speed unwinding process as yarn gets unwound spirally and when the bottom yarn gets unwound, it gets in contact with the outer Paper core edges and periphery and if this outer core periphery or edges are uneven, rough or damaged then yarn unwinding flow will be hampered during the high speed unwinding and that makes continuous filament yam broken. This results in breakage of yarn and also the bottom yarn does not completely unwind from the carrier resulting in the efficiency losses and yam wastages due to yam residue. So as to avoid these breakages and yam wastages, yarn processors use smooth Plastic unwinding caps or even spinners provide them with unwinding caps. So, the collars are very much important and a necessary element of this component. But because of this collar, Paper core cannot be spirally wound or sleeved onto this Plastic intermediate supporting core and therefore this intermediate Plastic or metal supporting core is designed as 2 pieces so that these 2 pieces with collar can be easily inserted or sandwiched between the outer and inner Paper core using injection molding technique or it could be made as 2 separate pieces first using injection molding technique and then can be inserted betweenouter and inner Paper core and can be locked or joined using hydraulic press or using adhesive or chemical process. The Same collar type- 2 piece Plastic or metal supporting core can also be made as both sided collar type single piece Plastic or metal supporting core and can be injected, inserted or sandwiched using injection molding and other supporting tools and techniques d. The component is designed in such a way that it will provide the required strength to the Hybrid carrier which is way higher than the Paper and it will also support the outer and inner Paper core keeping them separate from each other for outer and inner contact points i.e. yarn and machine parts respectively and binding them together at the same time as a single unit which will not allow them to shrink or compress, contract or elongate.

[0047] Open End Outer Paper Core a. This Component comes in direct contact with Yarn / fiber as the yarn is wound on it. The main reason why this core has to be Paper core and not the Plastic material is because of its notching. In spinning and also in other yarn manufacturing and processing, every yam carrier requires notching arrangement on a carrier where high speed winding takes place whether they use Plastic or Paper yarn carrier. Notching is nothing but a slot or special groove at the end of the carrier from where the yarn gets loaded or gets tangled during the high-speed winding. These notch or special groove sizes and patterns will vary based on spinning machine’s design, spinning techniques, different types and denier of yarn / fiber being wound. This notch / groove / slot on the carrier is very important because when the yam initially gets loaded on carrier whether by manual method i.e. by the machine operator or automatically using auto doffing technic (in Spinning it is always loaded automatically by machine using Auto doffing technique), This notch will play an important roll for entangling the yarn on the carrier during the initial yam loading on a carrier for winding at a very high speed take up dmm rotation i.e. at high revolution per minute (RPM). This also is the same case for other yarn processors for loading the yarn on a carrier at a very high take up drum RPM. Because the take up dmm shaft rotates at veryhigh speed i.e. drum shaft on which the carrier is loaded and from where the yarn package is derived or the yam loaded carrier is derived, an arrangement of notching is required to catch and entangle the yarn during the initial yam loading at high RPM. Moreover, the notch pattern and dimensions vary based on the different yam types, yarn deniers, machine designs and other factors. So it becomes difficult to make a standard common notching for all kinds of yam and machines if we want to develop a universally accepted standard carrier. So if the Plastic core is used as an outer component, we must include all of these notch patterns possibilities on a carrier in a single mould or dye made for the Plastic carrier or we should design different moulds and dyes for different notch patterns which becomes commercially challenging and impractical as the requirement will vary based on many factors as mentioned and also significantly it is not fixed that one spinner or processor will always make only one type of yam. So they can’t keep on buying or changing carriers based on these applications. So to make it feasible and practical, also there is a another challenge is that when carrier is load on winding machine chuck and when it start to rotate at the time of first layer of yarn come on the tube if there is a Plastic or metal surface it can be damage the yarn passing roller which is very important and cmcial part of machine. And also the machine part is very expensive. Machine manufacturer also not allowed to use any surface of tube instead of Paper surface.So we decided to make the outer component as Paper core because getting a notch on Paper is very easy using a Paper notching machine instead of having it predesigned on Plastic carrier or pre-moulded in the molding during the injection molding. b. So, to cater the requirements of all practicalities, the outer Paper core will be produced as an open-end cylinder with no notch initially on it. And then as per customer’s requirement, we can easily provide specific notch using Paper notching machines. This makes mass production and commercial production of these Hybrid carriers viable and universally accepted instead of being a proprietary carrier type for certain yarn spinners and yarn processors.
