Description

RECYCLED COMPOSITE TEXTILE AND ITS METHOD OF MANUFACTURING
TECHNICAL FIELD
The present invention relates to a use of composite waste material. In particular, though not exclusively, this invention relates to a recycled composite textile and a method of manufacturing the recycled composite textile.
BACKGROUND
A composite textile waste material is produced in every phase of the textile manufacturing process such as spinning, weaving, dyeing, finishing, garment manufacturing, or even at consumer end. For example, around 30 percent of raw material gets scrapped during garment manufacturing. The composite textile waste material poses a huge problem, irrespective of whether it is produced during production stage, processing stage, or at end-of-life cycle of textile products. The composite textile waste material is often dumped into landfills as a measure of waste management. Once in the landfill, some composite textile waste materials will not decompose. In the landfills, the composite textile waste material typically releases harmful gases (for example, methane, CO2, and the like) into atmosphere. Further, they also release toxic substances into groundwater and surrounding soil, leading to fatal impacts on living beings in nearby areas. Aforesaid harmful impacts of dumping the composite textile waste material in the landfills can be minimized by recycling/reusing the composite textile waste material.
Conventionally, there are two main ways to recycle/ re-use the textile waste material, for example, a mechanical recycling method and a chemical recycling method. However, existing techniques for recycling/reusing the composite textile waste material have several problems associated therewith. For example, the mechanical recycling method involves shredding the composite textile waste material into a fibrous form. However, shredding may result in shortening (for example, in length) of the composite textile waste material (for example, fibres, yarns, and the like) as well as weakening (for example, in terms of strength) of the composite textile waste material leading to a decrease in the usability of a product to be manufactured using the composite textile waste material. Further, the chemical recycling method entails a chemical process that de-polymerizes the composite textile waste material into a sludge of polymers and fibres. However, the chemical recycling is not fully developed to be used on a commercial scale and is expensive.
Therefore, in light of the foregoing discussion, there exists a need to overcome the aforementioned drawbacks associated with the existing techniques to recycle/re-use the composite textile material.
SUMMARY OF THE INVENTION
A first aspect of the invention provides a recycled composite textile comprising: a backing material coated with a polymer; and a plurality of patches arranged on the polymer, wherein the plurality of patches are arranged as at least one layer in a manner that each patch is arranged directly on the polymer or on a binder applied on at least one other patch of another layer, and wherein the patches in a given layer are arranged in a non-overlapping or minimally overlapping manner.
The term "recycled composite textile" refers to a textile product of predefined dimensions. The recycled composite textile has two sides: a front side and a back side. The front side of the recycled composite textile comprises the backing material coated with the polymer and the plurality of patches arranged on the polymer. The recycled composite textile is used as a raw material in textile industry to manufacture a variety of products.
The term "backing material" refers a component that primarily serves to support other components of the recycled composite textile. The backing material forms, protects, and strengthens a back of the recycled composite textile. The backing material has two sides: a first side and a second side, wherein the aforesaid components of the recycled composite textile are provided on the first side of the backing material and the second side of the backing material forms the back side of the recycled io composite textile. Optionally, the backing material is a flat sheet-like structure, that is in the form of a roll. In this regard, the backing material is unrolled before being used and the plurality of patches are arranged on it as described below. Alternatively, optionally, the backing material is in an un-rolled form. Optionally, the backing material have properties such as, bio sustainability, reusability, required strength to withstand weight of the plurality of patches, and the like.
Optionally, the backing material is implemented as at least one of: a paper, a textile, polymer. In one implementation, the backing material is implemented as the textile. Examples of the textile include, but are not limited to, cotton, recycled cotton, bioplastics, and bamboo. . In other implementation, the backing material is implemented as the paper. In such an implementation, a plurality of layers of the paper could be used to make the backing material. A number of the plurality of layers of the paper that are required depends upon a required thickness of the backing material. For example, a higher number of the plurality of layers of the paper may be required to make the backing material with high thickness than the backing material with low thickness. In yet another implementation, the backing material is implemented as a polymer. The polymer could be a polyester. Advantageously, the technical effect of using different types of the backing material is that the aforesaid material is easy to procure and use, and is inexpensive. Moreover, aforesaid material imparts required strength and structural stability to the recycled composite textile.
Further, the backing material is coated with the polymer. Optionally, at least one of the two sides of the backing material is coated with the polymer. The coating of the polymer on the backing material helps to impart required texture, strength, and other prerequisite properties to the backing material. Optionally, the polymer acts as an adhesive for the plurality of patches to be applied on the baking material as described below. Optionally, the polymer is coated on the backing material as at least one layer. In this regard, a single layer or multiple layers of the polymer may be coated on the backing material. Optionally, the at least one layer of the polymer have a predefined thickness lying in a range of 0.10 millimetres to 2 millimetres. Examples of the polymer could be, but are not limited to, 0.25mm, 0.5mm, and 1.25mm.
The patch refers to a piece of composite waste material. The piece of the composite waste material is processed to obtain the plurality of patches as described below before being applied to the polymer. The plurality of patches are arranged on the polymer in a form of at least one layer. In this regard, the plurality of patches are arranged in a single layer or in multiple layers, on the backing material that is polymer-coated. Optionally, the plurality of patches has a predefined weight. The predefined weight could lie in a range of 0.1 grams to 500 grams. Optionally, the plurality of patches has various shapes such as, but are not limited to, square, rectangle, circular, elliptical, and triangle.
Optionally, the plurality of patches have various irregular shapes. More optionally, the plurality of patches has random size distribution depending upon their various sources. The term "random size distribution" refers to a distribution of the plurality of patches in the given layer irrespective of sizes of the plurality of patches. For example, a given patch may be small and another given patch could be comparatively large in the given layer.
A given patch is arranged directly on the polymer to form the at least one layer of the plurality of patches on the backing material. Alternatively, a given patch is arranged on the binder present on the patches of the another layer to obtain multiple layers of the plurality of patches as s described in below paragraphs. Optionally, the plurality of patches are arranged on the polymer using at least one of: a person, a robot, a machine with a robotic arm.
Optionally, the binder is implemented as at least one of: the polymer, an epoxy powder, a fabric glue. Optionally, the epoxy powder is of low molecular weight. Advantageously, the technical effect of using one or more different kinds of the binder is that the plurality of patches gets adequately adhered on the binder leading to production of a stable and uniform recycled composite textile.
The patches in the given layer are arranged in a pre-determined manner.
Such manner will ensure consistency of material performance and/or consistency of visual appearance, among other things. It will be appreciated that the patches are arranged such that any two patches don't overlap onto each other. Alternatively, the patches are arranged such that any two patches have minimum overlapping onto each other.
The minimum overlapping could be along seam lines of the patches, around corners of the patches, or similar. Such an arrangement of the patches in the given layer is crucial to maintain uniformity and finish of the recycled composite textile which significantly enhances usability of the same. Nil or minimal overlapping ensures that the thickness of the recycled composite textile is consistent throughout.
The recycled composite textile has the plurality of patches arranged in a way that it offers several properties to the recycled composite textile which makes it suitable for various textile applications. The properties could be, but are not limited to, enhanced strength, structural stability, resistance against wear and tear, and the like. The plurality of patches used in the recycled composite textile are pieces of composite textile waste material which would have been otherwise subjected to landfilling as the measure of waste management, thereby leading to severe environmental pollution associated with the landfilling. Using such patches in the recycled composite textile considerably lowers such environmental pollution. The recycled composite textile considerably minimizes the composite textile waste material. Moreover, the recycled composite textile is a sustainable solution in the textile industry to be used as a raw material for manufacturing various products, as it saves considerable amount of energy sources such as electricity, water which would have been employed while manufacturing a product from scratch. The utilization of the recycled composite textile is easy and does not require much time, cost, and effort.
Optionally, the plurality of patches are implemented as at least two of: a knitted fibre patch, a woven fibre patch. In one example implementation, a mix of knitted fibre patches and woven fibre patches may be used as the plurality of patches to be applied in the given layer. In another example implementation, one layer may have the woven fibre patches and another layer may have the knitted fibre patches. The knitted fibre patch refers to a patch manufactured by knitting of a plurality of fibres.
The woven fibre patch refers to a patch manufactured by waving of the plurality of fibres. An arrangement of textile fibres in the knitted fibre patch is different from an arrangement of textile fibres in the woven fibre patch. Advantageously, utilization of different kind of the patches significantly enhances strength, finish, and mechanical properties of the recycled composite textile. Moreover, usage of different kind of the patches allows for manufacturing various types of recycled composite textiles using the different kinds of patches and thus significantly reduces the problem of environment pollution which would have otherwise occurred owing to landfilling of the same. Optionally, the recycled composite textile has a width lying in a range of 1 meter to 1.5 meters and a length lying in a range of 25 meters to 50 meters. The width lies in a range of 1 meter to 1.1 meters, 1 meter to 1.2 meters, 1 meter to 1.3 meters, 1.1 meters to 1.4 meters, 1.1 meters to 1.5 meters, 1.2 meters to 1.5 meters. The length lies in a range of 25 meters to 35 meters, 25 meters to 45 meters, 25 meters to 50 meters, 30 meters to 35 meters, 30 meters to 45 meters, 30 meters to 50 meters, 40 meters to 45 meters, 40 meters to 50 meters. Advantageously, aforesaid dimensions (the length and the width) of the recycled composite meets with a standard size requirement of raw materials required in a textile industry to manufacture various textile products. Owing to the above, the recycled composite textile is efficiently used in industries using standard textile equipment. Utilization of the recycled composite textile does not require re-designing of existing textile equipment.
A second aspect of the present invention provides a method of 15 manufacturing a recycled composite textile, the method comprising: - laying a backing material on a flat surface; applying a polymer on the backing material; - arranging a plurality of patches on the polymer, wherein the plurality of patches are arranged as at least one layer in a manner that 20 each patch is arranged directly on the polymer or on a binder applied on at least one other patch of another layer, and wherein patches in a given layer are arranged in a non-overlapping or minimally overlapping manner; and - pressing the plurality of patches arranged as the at least one layer to obtain the recycled composite textile.
In this regard, the backing material is laid on the flat surface to subsequently apply the polymer and the plurality of patches with ease. The flat surface could be a surface of a conveyor belt, a surface of a machine, a surface of a table, or similar. Optionally, the step of laying the backing material on the flat surface is performed using at least one of: a person, a robot, a machine with a robotic arm. Optionally, prior to laying the backing material, the backing material is unrolled so as to lay it on the flat surface by spreading it fully on the flat surface. Optionally, the backing material is unrolled using an unrolling machine.
Further, the polymer is applied on the backing material. The polymer imparts required texture, strength and other prerequisite properties to the backing material. Optionally, the polymer acts as an adhesive for the plurality of patches to be applied on the backing material as described below. Optionally, the step of applying the polymer on the backing material is performed using at least one of: a spray, a brush, a spreading tool, a coating device. Optionally, the spreading tool is at least one of: a roller, a spreading wheel, a spreader stick. More optionally, the coating device is at least one of: a screen coating device, a film coating device, a strip coating device. Aforesaid forms of application of the polymer result in adequate and even coating of the polymer to obtain a required thickness of the polymer.
Post applying the polymer on the backing material, the plurality of patches are arranged on the polymer. Herein, the arrangement of the plurality of patches on the polymer is optionally random, and is already described above. In some implementations, the plurality of patches are arranged as a single layer whereas in other implementations, the plurality of patches are arranged as a plurality of layers (i.e., multiple layers). Advantageously, the aforesaid arrangement of the plurality of patches imparts uniformity and stability to the recycled composite textile.
Lastly, when the plurality of patches arranged as the at least one layer, they are subjected to the step of pressing. Optionally, the step of pressing the patches in the given layer is performed by a pressing machine. Examples of the pressing machine could be, but are not limited to, heat press, steam press, and hand press. The plurality of patches are pressed to uniformly arrange the patches in the given layer. Optionally, the step of pressing is performed at a pressure lying in a range of lbar to 27 bar A-B units. Advantageously, the method of manufacturing the recycled composite textile is easy to perform, does not require large and expensive equipment and can be efficiently performed at a small scale as well.
Optionally, the method further comprises cutting the recycled composite textile to have a width lying in a range of 1 meter to 1.5 meters and a length lying in a range of 25 meters to 50 meters. The width lies in a range of 1 meter to 1.1 meters, 1 meter to 1.2 meters, 1 meter to 1.3 meters, 1.1 meters to 1.4 meters, 1.1 meters to 1.5 meters, 1.2 meters to 1.5 meters. The length lies in a range of 25 meters to 35 meters, 25 meters to 45 meters, 25 meters to 50 meters, 30 meters to 35 meters, 30 meters to 45 meters, 30 meters to 50 meters, 40 meters to 45 meters, 40 meters to 50 meters. Optionally, the step of cutting the recycled composite textile is performed by at least one of: a blade, a knife, a cutter, a machine having a cutting element. Alternatively, optionally, the step of cutting the recycled composite textile is performed manually by a person. Advantageously, the technical effect of manufacturing the recycled composite textile to have the aforesaid size is that it can be effectively used as a standard raw material for varying applications.
Moreover, usage of the recycled composite textile does not require any changes to the textile machines, as it can be easily used with standard textile machines.
