Effective date : Processes for producing regenerated fibers from post-consumer and post-industrial waste are disclosed. These regenerated fibers can be blended with other fibers, and intimately blended to provide a uniform blend of fibers.

The fibers can then be subjected to a carding process to orient the fibers. The regenerated fibers can be used in any application that would otherwise use virgin fibers, including their use to form woven or non-woven materials. Roughly a hundred billion pounds of post-industrial waste are landfilled or incinerated each year.

While these are good uses for pre or post industrial waste streams, consumers want more sustainable products in their everyday lives. The area of non-wovens, such as personal care products and household wipes, is a rapidly growing industry.

There would be a tremendous value associated with using fibers which have been repurposed through a regeneration process into such non-woven products, instead of using virgin materials.

This is particularly true for disposable products. The same is true of fibers that are spun into thread or yarn, and used to produce fabrics and other woven products.

Fibers that have been re-purposed using fiber regeneration technology could potentially offer a better product, at a cost advantage, resulting in an overall sustainable product that is good for the planet, consumers, and producers alike.

It is important to understand the difference between traditional recycling and regeneration of textile or other waste streams. This equipment when used takes textile waste and creates a shorter, weaker and damaged fiber. The present invention provides such processes, as well as products prepared using the processes.

A process for upcycling and transforming waste materials into value added consumer products is disclosed. The process adds characteristics of the material that could not be otherwise afforded using traditional virgin components, and which are aesthetically pleasing and offer value to a quality consumer product.

The process uses traditional fiber-handling equipment, but makes specialized and unique changes to create environmentally-sustaining products. In one embodiment, the process provides regenerated fibers that closely match virgin fibers, and which are obtained at a cost that is significantly less than the cost of producing virgin fibers. The process can use post-industrial or post-consumer waste streams as feedstocks.

The waste streams include fiber-containing materials, and the fibers can be isolated from the waste streams and regenerated in order to achieve maximum benefit from the fiber lengths, strengths, and other properties.

The fibers can then be efficiently processed through traditional or modified woven or non-woven processes into finished roll goods.

The finished roll goods can then be converted into a variety of consumer products. The process described herein takes us several steps forward relative to other processes, in that it eliminates soft threads and individualizes the fibers, and due to this new process, it can be used to regenerate and upcycle to transform the hundreds of millions of pounds of waste that would have otherwise found its way to a landfill or incinerator.

The process creates products that are superior in certain qualities and characteristics to those made from virgin materials, typically at less cost, or in a cost competitive manner relative to processes using virgin materials. Representative post industrial or post consumer waste streams that can be used as feedstocks include fabrics such as knits, for example, t-shirts, socks, undergarments; wovens, from items such as shirting, sheeting, bottom weight, denim, bedding, and upholstery; and non-wovens.

These materials can be bleached white, or optically brightened or dyed fabrics, and can be used to increase value and reduce cost by using the materials as they are to create a higher valued product without using additional bleaches or dye baths to achieve the same results. Dyed Cotton fibers or yarns are more expensive and take additional chemicals and waste water which increases the carbon output, chemicals and water usage, but these regenerated fibers have either been thru bleaching, optical brightening or dyeing processes and therefore to achieve the same final results to not have to be bleached, optically brightened or dyed and can have a better cost basis for the manufacturer and the same or better aesthetic value for the consumer.

For example, a baby wipe can be made with regenerated cotton from knits and wovens, where the cotton is already white, so no bleaching or optical brighteners are necessary to add to this process. At the same time, creating a non-woven out of a colored fiber waste stream, such as denim, can result in a pale blue wiping cloth perfect for industrial or household non-wovens, without the need for additional dyes or colorants, to create a value added product for the consumer product arena.

In this process, to create a total value stream, it is advantageous to realize that all i. The example above of the baby wipe is created from a median fiber length of typically 0.

For example, the trim from a t-shirt manufacturer can be regenerated and upcycled to create yarn and knitted fabric to go back into a t-shirt of equal quality. The process can also incorporate other fibers, including natural and synthetic fibers, such as fibers from seeds, stalks, basts, stems, leaves, or fruits, fibers derived from animal hair, and silk fibers or other protein based fibers.

The other fibers can be transformed natural fibers i. The other fibers can also include inorganic fibers, such as glass fibers and metal fibers. At least a portion of the fibers are isolated from post-industrial or post-consumer waste. To isolate fibers from these materials, which are previously woven, knitted, or bonded together by a non-wovens process, it is necessary to un-weave or un-twist the threads.

This can be accomplished, for example, by removing post-treatments from the threads, which thins the threads and loosens the knots or twists. In the case of cellulosic fibers, a portion of the cellulosic fiber can be degraded, for example, using a cellulose enzyme.

The intimate blending can also provide color uniformity, which can otherwise be difficult to attain when different batches of fibers are used to produce a single non-woven fabric. Intimate blending involves initially humidifying or treating the fibers, which strengthens the fibers, if they are organic fibers such as cotton, cotton blends or fibers such as rayon or ramie, reduces dust particles for better product performance and, protecting the fibers from tensile elongation, and reduces neps.

Multiple hoppers can be used, for example, where blends of different fibers are intended. Examples include using regenerated cotton fibers in combination with one or more virgin or regenerated plant fibers, such as wood, kenaf, and the like, or synthetic fibers, such as polyester or polyolefin fibers. However, the regenerated cotton fibers can be used by themselves, without adding other fibers. The fibers at this stage in the process are randomly oriented, but can optionally be oriented using a non-woven or textile carding process.

The fibers can be subjected to one or more chemical treatments, Representative treatments include humidification, the addition of surfactants to provide more hydrophilic products, which can be important when the fibers are used to prepare wipes or other substrates used in aqueous solutions, or when the fibers are used in substrates needing to be used to absorb liquids.

In one embodiment, the randomly-oriented, intimately blended fibers are subjected to a carding process to form a uniform fiber web. Such a uniform fiber web is typically passed, over a conveyor belt or a web, where it can optionally be combined with one or more layers of fibers or webs of fibers. The regenerated fibers can be used in processes where they are layered with one or more layers of fibers that are different fibers than the regenerated fibers.

The additional one or more layers can comprise randomly-oriented fibers, for example, laid down in an air-laid process over the top of the oriented fiber web, and, optionally, a further oriented fiber web can be laid on top of the randomly-oriented fibers.

In other embodiments, the regenerated fibers are combined with polyolefin or other thermoplastic fibers, so that the fibers can be bonded in a thermal fashion, rather than a chemical or mechanical fashion, when used in non-woven applications. In one embodiment, a cationic wet-strength resin is applied to the fibers, for example, via dipping, spraying, and the like, to impart additional strength to the fibers, for example, when they are used in wet-laid applications to form wipes or other products.

The regenerated fibers can find use in a number of end-products, including knits, woven and non-woven products.

Woven products include textiles, rugs, apparel, and the like. Examples of some of the potential non-woven products include, but are not limited to, hygiene products, medical products, filters, geotextiles, and other products, and specifically include wipes.

The wipes can be adapted to include a variety of additional components, including moisturizers, cleansers, essential oils, antibacterials, antivirals, antimicrobial cationic polymers, and the like. The regeneration process is described in detail below. Optionally, the fibers can be subjected to one or more chemical treatments, and can be spun into yarn or thread, and used to make woven products, or used directly in non-woven products.

Each of the process steps is described in more detail below. The present invention will be better understood with reference to the following definitions:.

As described in more detail herein, fibers are formed into a web using a variety of processes, which include techniques for a orienting or not orienting the fibers, b laying the fibers down to form a web, and c bonding the fibers in the web to form a non-woven material.

Carding processes are typically used to orient the fibers. The fibers can be laid down on a moving conveyor belt using a variety of techniques, including direct carding lay, air carding, air lay, wet lay, and the like. The laid-down fibers can then be bonded using one or more of mechanical, chemical, or thermal bonding techniques.

Terms of art in connection with the laying down of fibers, and the bonding of the laid-down fibers, are defined below. Yarn is defined herein as a long continuous length of interlocked fibers, suitable for use in the production of textiles, sewing, knitting, weaving and ropemaking. Yarn can be made from any number of synthetic or natural fibers.

Very thin yarn is referred to as thread. Yarns are made up of any number of plys, each ply being a single thread, with these threads being twisted plied together to make the final yarn. In a non-woven, the assembly of textile fibers is held together 1 by mechanical interlocking in a random web or mat; 2 by fusing of the fibers, as in the case of thermoplastic fibers; or 3 by bonding with a cementing medium such as starch, casein, rubber latex, a cellulose derivative or synthetic resin.

Initially, the fibers may be oriented in one direction or may be deposited in a random manner. This web or sheet is then bonded together using a variety of methods, which are described in detail below.

Various techniques can be used to prepare the initial assembly of textile fibers, including air carding, direct lay carding, air lay, and wet lay. These ordered fibers can then be passed on to other processes that are specific to the desired end use of the fiber.

Carding can also be used to create blends of different fibers or different colors. When blending, the carding process combines the different fibers into a substantially homogeneous mix. Commercial cards commonly have rollers, and may optionally have systems in place to remove various contaminants from the fibers.

A representative carder is shown in FIG. As they are transferred to the swift, many of the fibers are straightened and laid into the swift's card cloth. As swift 10 carries the fibers forward from the nippers 30 , those fibers that are not yet straightened are picked up by a worker 40 and carried over the top to its paired stripper Relative to the surface speed of the swift 10 , the worker 40 turns quite slowly.

This has the effect of reversing the fiber. The stripper 20 , which turns at a higher speed than the worker 40 , pulls fibers from the worker 40 and passes them to the swift The stripper's relative surface speed is slower than the swift's, so the swift 10 pulls the fibers from the stripper 20 for additional straightening.

Straightened fibers are carried by the swift 10 to the fancy The fancy's card cloth is designed to engage with the swift's card cloth so that the fibers are lifted to the tips of the swift's card cloth and carried by the swift 10 to the doffer The fancy 50 and the swift 10 are the only rollers in the carding process that actually touch. The slowly turning doffer 60 removes the fibers from the swift 10 and carries them to a fly comb not shown where they are stripped from the doffer.

A fine web of more or less parallel fiber, a few fibers thick and as wide as the carder's rollers, exits the carder at the fly comb by gravity or other mechanical means. The web can then be stored, or further processes into a non-woven material using the additional process steps described herein. The shape, length, diameter, and spacing of these wire pins is dictated by the card designer and the particular requirements of the application where the card cloth will be used.

In order to maintain the length and strength of the fibers, it is preferred to control the moisture content of the fibers as they are carried out through the various process steps. Ambient temperature i. In one embodiment, the product includes relatively high percentages of regenerated cotton fibers, and therefore requires relatively higher humidity. Modification of Textile Carding and Spinning Equipment.

While the fibers have the length and strength requirements found in natural virgin fibers, there can be dust associated with the fibers that are a bit smaller than that of traditional fibers therefore modifications must be considered in further carding, drawing, roving and spinning equipment.

It is typical in this process that additional cleaning, with light suction points throughout the equipment, can be used to maximize the performance of these fibers. Due to the short staple that is inherent in regenerated fibers, there may be dust particles that accompany the fiber throughout the regeneration process.

However, the process of treating textiles with dyestuffs is often expensive, inefficient and environmentally unsound. For example, traditional cellulose dyeing processes require the use of large amounts of water, salt, alkali, and heat and can generate excessive pollution. In addition, the inefficiency of traditional textile dyeing results in poor ability to achieve a desired color, as well as problems such as bleeding and fading. These problems can lead to the need for large amounts of water, energy, dye, and chemicals to achieve desired colors, and therefore higher costs and greater environmental impact during the dyeing processes.
