Thus, appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment, but may. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner, as would be apparent to a person skilled in the art from this disclosure, in one or more embodiments. Furthermore, while some embodiments described herein include some but not other features included in other embodiments, combinations of features of different embodiments are meant to be within the scope of the invention, and form different embodiments, as would be understood by those in the art. For example, in the following claims, any of the claimed embodiments can be used in any combination. In a first aspect, the invention provides a system for disassembling garments that are at least partially assembled with heat sensitive yarn, glues and/or heat- demountable rivets. The system comprises at least one heating chamber in connection with means for providing heated air of a temperature of at least 100°C or superheated steam to the heating chamber. Said heating chamber having at least one opening through which clothing can enter said heating chamber wherein said system further comprises a rotating drum section comprising a drum, wherein said drum section is located within said heating chamber or configured to be moved in and out said heating chamber. The system permits weakening and breaking down the mechanical properties of any heat sensitive yarns, glues, heat-demountable rivets or buttons by means of thermal and mechanical stress. Said mechanical stress being provided by the rotation of a drum while said yarns, glues, heat-demountable rivets or buttons are still warm.

The term "heat sensitive yarn" refers to a thread with a known melting point or melting temperature, in which the thread melts when it is heated to a temperature within the range of the melting temperature of the thread.

A "yarn" or thread is used to refer to a thread that is made by spinning fibers or to refer to filament yarns, that are basically endless and thus already form a yarn. In the context of the present invention, a distinction is made between "standard yarn" and "heat sensitive yarn".

In an embodiment, the heating chamber has a first and second heating section. By preference, each section of the heating chamber is in connection with means for providing heated air of a temperature of at least 100°C or superheated steam or heated inert gas. By preference each section has one inlet and at least one outlet for circulating said heated air, superheated steam or heated inert gas. In this way, each chamber can be provided with different heating fluids, which permits different atmospheres to be created within each section.

In an embodiment, said first and second section are located upstream of said drum section. In another embodiment said drum section is located within said second heating section. In either embodiment, each heating section before the drum section permits pre-heating the garments, thus weakening the mechanical properties of any heat sensitive yarns, glues, heat-demountable rivets or buttons before said products enter the drum section. This permits making a more efficient use of the mechanical stress applied by the rotating drum as any heat sensitive yarns, glues, heat- demountable rivets or buttons are already weakened before being subject to said mechanical stress.

In an embodiment, said system comprises a transportation unit, for transporting said garments through at least part of said heating chamber. By preference, said transportation unit is able to operate at a temperature of at least 120°C, more preferably, 150°C, 170°C, 180, 190°C, most preferably above 220°C. By preference, said transportation unit extends from the entrance of the heating chamber to the drum section, more preferably from the entrance of the heating chamber until 200mm inside the drum section, most preferably 300mm. In this way effective transportation of the garments into the drum in the drum section is advantageously ensured.

In a further or another embodiment, said transportation element comprises at least two transportation sub-units, wherein each unit may be set to a pre-defined speed. In this way, it is possible to vary the time the garments are exposed to each predefined temperature. This is particularly advantageous when varying between garments having synthetic fibers to garments having only natural fibers. By preference, each transportation sub-unit is either a conveyor or a drum. More preferably, the first transportation sub-unit is a conveyor and the second transportation sub unit is a drum. In this way, the garments enter the heating chamber and into a first heating section where said garments are pre-heated, by preference using superheated steam or heated inert gas, followed by second preheating stage inside a drum, and before entering the drum section of the heating chamber. Most preferably each transportation sub-unit is a drum. This permits exposing more of the surface area of the garments to the heated air, superheated steam and/or heated inert gas, thereby guaranteeing a more efficient heat transfer during a preheating stage. In order to improve the conveyance of garments through the inside of each drum, each drum may include reciprocating inserts, rams, screws, ejector plates and/or pins. By preference, each drum is inclined at least 2° to 10° downstream. Yet more preferably, the internal surface of each drum includes pins and/or paddles arranged in a helical pattern extending at least 80%, preferably 90% of the length of said drum. In this way, conveyance of the garments inside of each drum is guaranteed. Most preferably, the protrusion of said paddles and/or pins towards the axis of the drum is adjustable. In this way, the mechanical forces to which the garments are exposed during tumbling are advantageously adjustable. This is particularly relevant when thinner garments are processed. In an embodiment, one of the sections of the heating chamber is in connection with means to provide air, super-heated steam or inert gas heated to a temperature at least 20°C lower than the temperature of every other section of the heating chamber. More preferably, the drum section is in connection with means to provide air, superheated steam or inert gas heated to a temperature at least 20°C lower than the temperature of every other section of the heating chamber. In this way, the separated garments reach a lower temperature before being exposed to the outside of the system, thereby reducing the risk of damage to said separated garments due to oxidation. Most preferably, each section has its own sources of hot air, superheated steam and heated inert gas. Yet more preferably, each inlet of each section of the heating chamber is modulated, for example by means of at least one valve disposed before or to each inlet. In this way the volume and speed of hot air, superheated steam or heated inert gas entering each section can, advantageously, be controlled. Most preferably, also each outlet is modulated, for example by means of at least one valve disposed before or to each outlet. By being able to modulate the inlets and outlets of each section, pressure, humidity, temperature and oxygen concentration inside each section is also controllable. More advantageously still, different pressure, humidity, temperature and oxygen concentration can be set for each section, even if the source if hot air, superheated steam and heated inert gas are the same for all sections.

In an embodiment, the drum in said drum section is equipped with orifices in the drum wall, for allowing the evacuation and/or presorting of disassembled textile components such as buttons. By preference, the orifices are rectangular, circular or elliptical. In this way, heated air, superheated steam and/or heated inert gas will easily permeate through the walls of the drum, increasing heat transfer and thus, the efficiency of the system. More importantly, the orifices of the drum permit automating the separation of the larger pieces of the garments from any smaller pieces of the same garments, which larger pieces then follow different paths in the system. By preference, the orifices have a size between 20mm and 60mm. More preferably the drum includes a rotatable cylindrical jacket disposed to the outer surface of said drum, said jacket having orifices similar in size and location to those of the drum. In this way, the orifices of the drum are advantageously adjustable in size. This permits selecting which elements of the garments will fall from the drum during tumbling.

In an embodiment, a collection tray is present below the drum section for collecting said disassembled textile components. This advantageously permits splitting the larger elements of the garments from those of smaller size into at least two output paths and to collect the disassembled textile components for further downstream reuse or recycling.

In a preferred embodiment of the system, the walls of the heating chamber are insulated. In this way, heat exchanges with the outside of the heating chamber are minimized, which advantageously makes using the system both safer and energetically efficient.

In a further or another embodiment, at least one of the walls of the heating chamber includes a platform configured to move at least one drum in and out of the heating chamber. In this way, access to the inside of the heating chamber is made easier for maintenance, and/or loading of the drum. Preferably, the platform includes a surface configured to air-tightly close the heating chamber. This permits avoiding losing hot fluids, particles or heat, which losses would be detrimental to both the efficiency and safety of the system.

In further or another embodiment, the system comprises a fan in fluid connection with a heater, which heater is in further connection with at least an inlet of the heating chamber. By preference, said system has an outlet in fluid connection with a filter, which filter is configured to be in fluid connection with the inlet of the fan. In this way, the system can function in a closed loop, thereby minimizing heat losses, most importantly by means of loss of heat carrying fluids, to the outside of the system. This further, and very advantageously, increases the energy efficiency of the system, thereby reducing costs and environmental impact of using the system.

In a further or another embodiment, the heating chamber is provided with a first opening and a second opening, which first opening is configured to be connected to an incoming first conveyor belt, and which second opening is configured to be connected to an outgoing second conveyor belt. Preferably, the conveyor belts connected to the first and second openings of the heating chamber are further provided with a shroud. In this way, the drum can operate continuously while the shroud permit minimizing heat exchanges with the outside of the system. Preferably, a heat exchanger or secondary duct at the end of the second opening can divert some of the heat towards the space between the incoming conveyor belt and its shroud. In this way, the garments being transported by the incoming conveyor belt are advantageously pre-heated, thereby reducing the tumbling time of the garments, further enhancing the energy efficiency and output of the system. More preferably still, the first conveyor belt and the second conveyor belt are oriented between 10° and 90° longitudinal axis of the heating chamber. In this way, the heating chamber is elevated relative to the input and output openings. This permits taking advantage of the tendency of the warmer less dense gasses to raise. In this way any heating fluid used to heat any part of the heating chamber is advantageously kept in said heating chamber.

In a further or another embodiment, temperature in the heating chamber can be set between 100°C and 220 °C. Preferably, temperature in the heating chamber can be set between 100°C and 300°C. In this way, multiple types of garments and heat sensitive yarns can be treated while reducing the risk of damaging any part of the garments. Preferably, multiple pre-set temperature modes are made available to the operator by means of a control panel. In this way, the risk of human error is minimized while also minimizing the risk of excessive energy consumption. Still more preferably, temperature in the heating chamber should be at least about 20°C above the melting point of the heat sensitive yarn.

A second aspect of the invention relates to a method for disassembling garments that are at least partially assembled with heat sensitive yarn and/or heat- demountable rivets said disassembling occurs by means of a disassembling system comprising a heating chamber and a drums section, wherein said garments are entered into said system and. In this method said garments are subjected to air of a temperature of at least 100°C, a heated inert gas or superheated steam while placed under mechanical stress by means of a tumbling and/or rotating motion.

In a preferred embodiment, the method, comprises the steps of:

- setting a disassembly temperature to be attained in the heating chamber; heating and circulating at least one fluid until the set disassembly temperature is attained; loading the system with garments to be disassembled;

- tumbling the garments at the pre-set disassembly temperature in the drum section; and retrieving the disassembled garments from the drum section.

In a further or another preferred embodiment, the steps of loading the drum section with garments and unloading the drum section are done in batches and by providing the operator with direct access to the drum. This permits the use of closed loop system, such that a very high energy efficiency and safety are advantageously maintained during operation. In a further or another embodiment, the steps of loading the drum with garments and unloading the drum are done continuously and by means of at least one conveyor and/or at least one additional drum. This permits constant operation, and therefore, a higher output.

In an embodiment, the step of loading the drum section with garments to be disassembled is preceded by a step of pre-heating the garments in a first heating section of the heating chamber. By preference, said first section is upstream from the drum section. This advantageously permits reducing the mechanical strength of any heat-sensitive yarn, glue, rivet and/or button before the garments enter the drum. This permits a more efficient use of the full length of the drum to impart mechanical stress upon the garments as said mechanical stress starts to breaks said heat-sensitive yarn, glue, rivet and/or button as soon as the products enter the drum.

By preference, the step of setting a disassembly temperature to be attained in the heating chamber further includes a step of setting a tumbling time of said drum. More preferably, the step of setting a tumbling time further includes a step of setting a pre-heating time. Most preferably, the pre-eating time is equal, preferably longer than the tumbling time. In this way, the tumbling operation in not a bottleneck in the process, which permits avoiding excessive heat transfer to the garments during the pre-heating stage.

In an embodiment, the step of pre-heating the garments is preceded by a step of heating and circulating at least one fluid in the first section until the a temperature at least 20°C above the set disassembly temperature is attained. By preference, said garments are heated in a two-step heating process, wherein the temperature in the second heating step will be lower, preferably at least 20°C lower, than the temperature in the first heating step, wherein in at least one step superheated steam is used as source of heating. By preference, the second heating step is carried out inside the drum. In this way, the separated garments leaving the drum have a lower temperature, which temperature is sufficiently low so as to avoid oxidation damage to the garments.

Method according to any of the previous claims, characterized in that, if the oxygen concentration inside the heating chamber is above 10%, heating of the heating chamber is carried out with superheated steam or heated inert gas. In this way, the oxygen concentration inside the chamber is kept lower than 10%, which prevents oxidation damage to the textile material during processing.

In a further or another embodiment, superheated steam is provided to the heating chamber by a steam generator or boiler. As known to those skilled in the art, steam systems are of very common use in a wide variety of industries. By making use of existing steam systems, the cost of acquiring and using the system can be further reduced. Furthermore, steam leaving the garment disassembly system can still be used in other operations with lower heat requirements. The use of superheated steam from sources external to the system permits not only preventing oxidation of the textile material but contribute also to a more efficient overall operation of the plant where the system is operating.

In an embodiment, the fluid used is a heated inert gas. The use of a heated inert gas advantageously displaces the oxygen present in the heating chamber, which permits not only preventing oxidation of the textile material but contribute also to a more efficient overall operation of the plant where the system is operating.

In an embodiment, said disassembling comprises at least partially removing textile components such as buttons, zippers or rivets from said garments, wherein said removed textile components are evacuated from said system by means of orifices present in said drum. By preference, said textile components are evacuated by means of a tray positioned below the drum section. This permits avoiding further separation steps elsewhere in the factory, while allowing easy collection of the smaller elements of the garments.

In an, said method is performed in a system according the first aspect of the invention. Said system permits regulating the both the thermal and mechanical load to which the garments are subject to. In this way, garments having varying degrees thermal and mechanical resilience can be treated.

In order to ensure homogenous heat distribution and sufficient mechanical load is imparted upon the garments during tumbling, the speed of the drum should be at least 30 RPM and up to 50 RPM. Preferably, the rotation speed of the drum should be adjustable.

Tumbling duration varies according to the types and quantity of garments being treated. For example, the system in a closed loop configuration was tested for the disassembly of 14 pairs of jeans. In a first instance, air was used as heat carrying fluid, which air was introduced into the heating chamber at about lOm/s. The process was carried out for 15 minutes, after which full disassembly of the garments was achieved. In a second instance, the same test was carried out, also for 14 pairs of jeans identical to those treated in the first test. In this second instance, superheated steam was used as heat carrying fluid, said heat being introduced into the heating chamber at about lOm/s for a period of 10 minutes, after which full disassembly of the garments was achieved.

The invention is further described by the following non-limiting examples which further illustrate the invention, and are not intended to, nor should they be interpreted to, limit the scope of the invention.
