Description

[Technical field]

[0001] The invention to which this application relates is a resin provided for use in forming creases in clothing to which the resin is applied. The creases typically extend along at least part of the length of a trouser leg, a shirt sleeve or a shirt part, but can be provided at any required location of the clothing, it being recognized that for each garment, e.g. a pair of trousers, there will be several crease lines, each of which will receive a line of resin along the crease line. The resin is applied as a ribbon of resin, i.e. a narrow line, and cannot be applied as a surface coating of a large area, as this would limit the flexibility and / or comfort of wearing the garment. The objective is to provide a line of resin along the inner surface of the garment such that the line of resin is located along the base of the V-shaped crease line, so as to provide greater strength and hardness to the crease line and thus allow the crease line to retain its shape for a longer period of time than if the crease line was simply formed by ironing or pressing the garment material. This means that the appearance of the garment will therefore be retained for a longer period of time, with the crease line being visible from the outside. The resin lines or ribbons are typically applied immediately after manufacture of the garment and may then be applied from time to time as an optional add-on service, typically as part of a garment cleaning service. [Background technology]

[0002] The resin is initially provided in a fluid state and held in a reservoir, in one example in the form of a cartridge, from which the resin is dispensed in a controlled manner through an exit opening as a line or ribbon of fluid resin. Alternatively, the resin can be held in a larger reservoir, such as a drum, and then pumped as a fluid supply from the drum to an applicator, which may or may not include a smaller holding chamber, from which the fluid resin is applied as a line or ribbon from an exit opening along a fold line.

[0003] Typical resins are provided such that when applied to the crease in a cartridge or other dispensing means, the resin will cure and begin to harden upon exposure to atmospheric conditions, thus forming a relatively hard, solid ribbon of resin along the crease line, which has the effect of maintaining the crease in the garment for a longer period of time than if the resin had not been applied to the crease line.

[0004] When the garment is worn and the resin is applied correctly, the crease lines in the garment are maintained as the resin hardens, while the resin is applied to the inner surface of the garment such that it is not visible from the outside of the garment. This method and resin have been used for some time and with considerable commercial success worldwide. However, it has been found that there is an ever-increasing resistance from both legislators and commercial users to the use of conventional resins, which typically contain tin or organotin components as the curing component. The resistance is due to the fact that the use of tin, or organotin or other tin derivatives in resins, and the use of resins in garments worn by humans, is seen as presenting a risk of health problems, primarily to the workers who apply the resin material to the garment, and also potentially to the end user. This is due to the results of studies which show that tin, in isolated form and when not used in combination with other components, may possibly be carcinogenic. Summary of the Invention [Problem to be solved by the invention]

[0005] Having recognized that potential problems exist, the applicant has an object of the present invention to provide a resin material that is sufficiently fluid so that the resin can be applied as a line or ribbon using an application device during the resin application process, and that once applied, hardens to a sufficient degree to enable the benefit of maintaining creases in the garment over time.

[0006] A further object is to provide the resin in a form that allows it to be applied substantially invisible to the naked eye and have no detrimental effect on the appearance of the garment, and to further ensure that once applied to the garment, the cured resin is maintained in a condition such that it will not easily shift or crack.

[0007] The applicants have described in their co-pending GB Patent Application Publication No. 2606925, the contents of which are incorporated herein by reference, that they provide resins which are free of tin and / or organotin components.

[0008] It is an object of the present invention to provide a further form of resin which has the advantage of being tin and / or organotin free, and yet has the ability to allow the resin to be applied in a sufficiently fluid state to allow the resin to be applied as a ribbon along a garment crease and then cured and hardened so as to be retained in position along the base of the crease so as to maintain the crease in the garment.A further object is to provide an improved method of resin application, and to provide garments having crease lines which include a ribbon of resin material along at least a portion of the crease line, the resin being located on the inner surface of the garment when the garment is worn. [Means for solving the problem]

[0009] In a first aspect of the invention, there is provided a resin for application as a ribbon or line along at least a portion of a crease line of a garment to aid in extending the retention of the crease line in the garment, said resin being provided in a substantially fluid first form that is usable for a sufficient period of time, said resin being applied along the crease line and allowing it to adhere to textile fibres adjacent the crease line, and once applied, curing to assume a second form, said resin hardening and bonding to the crease line, said resin comprising a catalyst to aid in curing of said resin, said catalyst comprising any or any combination of platinum, peroxide, organic amine, titanium, zirconium, tertiary amine, organosilane, iron, copper and / or non-metals.

[0010] Typically the hardener is a substantially tin and / or organotin free composition, preferably free of tin or organotin or tin derivatives.

[0011] Providing a resin that is tin or organotin free means that potential health risks due to the presence of tin are avoided, both during preparation and filling of cartridges, dispensing of the resin into garment creases, and also during wearing of garments to which the resin has been applied.

[0012] In one embodiment, the resin comprises a cure system in the form of an acetate, which in one embodiment is a crosslinked acetate.

[0013] In one embodiment, the resin comprises amorphous silicic acid hydrate, methylsilanetriyl triacetate, diacetoxydi-tert-butoxysilane, hexanoic acid, dodecamethylcyclohexasiloxane, acetic acid, and octamethylcyclotetrasiloxane.

[0014] In one embodiment, the amorphous silicic acid hydrate is replaced with bismuth tris(2-ethylhexanoate).

[0015] In one embodiment, the resin comprises triacetoxyethylsilane, octamethylcyclotetrasiloxane, polybutylene terephthalate (PBT), and / or materials sometimes referred to as vRVB materials, including dodecamethylcyclohexasiloxane and decamethylcyclopentasiloxane.

[0016] In either embodiment, the hardening effect of the hardener, and therefore the setting of the resin, occurs as the resin is applied to the garment along the crease lines.

[0017] Typically, curing occurs as a result of exposure of the resin to the surrounding environment, typically exposure to moisture in the environment in which the resin is applied. However, in other embodiments, curing can occur or be aided by mixing the cure system components together and / or exposure to specific conditions, such as heat or ultraviolet light. Typically, the need for specific conditions depends on the particular type or blend of curing agents included in the resin.

[0018] Typically the resin comprises a silicone, and in one embodiment is a vulcanized silicone rubber, hi one embodiment the resin, when cured, resists damage upon ongoing exposure to ambient environmental conditions up to 180 degrees Celsius.

[0019] Typically, the resin is substantially colorless.

[0020] Typically, the resin is of the type that changes from a substantially non-sagging state to a flowable state, also referred to as a non-sagging to self-leveling state changeable resin. This means that when the resin is applied from a reservoir, it is in a substantially non-sagging form, which means that the resin does not substantially sag and does not change its shape from the shape in which it is applied, and therefore consistently holds its shape, but when applied to a garment fabric and cured by exposure to moisture in the surrounding environment, the resin takes on a more flowable form, which allows the resin to be absorbed into the fabric fibers at the crease line, and therefore to be more effectively bonded to the fabric, and to have an improved effect on crease retention for a longer period of time.

[0021] In a further aspect of the invention there is provided a method of applying resin material to a crease line of a garment to assist in extending retention of the crease line, said method comprising the steps of providing a supply of resin material in fluid form to a dispensing means having an outlet opening for controlled movement of the fluid resin through the outlet opening, and guiding relative movement of the outlet opening along the crease line formed in the garment, such that the fluid resin is applied from the outlet opening as a ribbon or line along the base of a substantially V-shaped crease line, said resin curing and hardening allowing said resin to bond to the fabric from which the garment is formed along the crease line, and a catalyst is provided to the resin allowing the resin to harden, the catalyst comprising any one or any combination of platinum, peroxide, organic amine, titanium, zirconium, tertiary amine, organosilane, iron, copper and / or non-metals.

[0022] In one embodiment, the cure system contained in the resin is a crosslinked acetate.

[0023] In one embodiment, when the resin is applied from the exit opening, it is in a substantially non-droopy form and, once applied from said exit opening, typically as curing begins to occur, the resin changes to a more flowable form, allowing the resin to be absorbed into and bond with the fibers of the fabric adjacent and in contact with the fold lines.

[0024] In a further aspect of the invention, a garment is provided that includes at least one crease line formed, and a resin material as defined herein is applied along at least a portion of the crease line and hardens to assist in retaining the crease in the garment and bonds to the garment fabric along said at least a portion of the crease line.

[0025] In one embodiment, the fold line is V-shaped in cross section and the resin is applied along the base of at least a portion of the fold line, and the resin is applied to a body-facing surface of the garment when the garment is worn such that the resin is located between the garment fabric and the wearer of the garment.

[0026] In one embodiment, the garment includes a number of crease lines along which resin is applied.

[0027] In yet a further aspect of the invention there is provided an apparatus for use in applying a resin as defined herein along a fold line of a garment, said apparatus comprising means for moving said resin in a fluid state from a reservoir of resin to and through an outlet opening to which the reservoir is connected, and means for effecting relative movement of the outlet opening and the garment so that the resin in a fluid state is applied as a ribbon or line along the base of at least a portion of the fold line and then hardens, sets and bonds to the garment fabric.

[0028] In one embodiment, the reservoir and outlet opening, and at least part of the means for moving the resin, are provided as integral parts of a cartridge, the cartridge also including or associated with guiding means for guiding movement of the cartridge along the fold line as resin is applied along the fold line.

[0029] In one embodiment, further guiding means are provided in the form of a support surface in which one or more grooves are formed to receive and hold the fold lines of the garment along which the resin is applied.

[0030] In one embodiment, cure activation occurs during and / or after the resin material is applied to the crease lines of the garment and the resin is at least partially absorbed into the garment and hardens.

[0031] A retaining means may also be included as part of the cartridge to allow guided relative movement of the outlet opening and fold lines to apply the resin along its base as it is pumped or otherwise moved towards and through the outlet opening where it is dispensed from the reservoir.

[0032] Typically, the amount of resin, reservoir size and / or cartridge size are selected with respect to the particular use or number of uses required from each cartridge. In one embodiment, the cartridges are refillable.

[0033] In one embodiment, the reservoir is a drum or other container separate from the application means and is connected to the application means via a pipe or tube for pumping the resin towards the outlet opening of the application means, in this embodiment the application means includes a body portion in which the outlet opening and the guiding means may be located.

[0034] Particular embodiments of the present invention will now be described with reference to the accompanying drawings. [Brief description of the drawings]

[0035] [Figure 1a] 1 illustrates an end view of one embodiment of an apparatus used to apply resin to creases in clothing. [Figure 1b] 1 illustrates a front view of one embodiment of an apparatus used to apply a hardening resin material along creases in clothing. [Diagram 2] 1 illustrates a further embodiment of an apparatus for use in applying resin according to the present invention. [Figure 3a] FIG. 1a illustrates a resin as it is being applied to a crease line of a garment, according to one embodiment of the present invention, shown in cross-section. [Figure 3b] 3b illustrates resin being applied to the crease lines of the garment of FIG. 3a according to one embodiment of the present invention; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0036] 1a and 1b, an apparatus 2 is illustrated for use in applying a fluid resin material 12 to a crease line 6 of a garment 8 to increase the performance of the crease line, i.e., increase the period that the crease line will be retained, thereby maintaining a desirable appearance of the garment for a longer period of time. Typically, the resin material 12 is applied at the time of manufacture of the garment and / or at times thereafter, for example, when the garment is cleaned, and typically the application of the resin is applied by a commercial manufacturer or dry cleaner, rather than by the person who purchases and wears the garment. The garment may be of any form in which a crease line is provided, but is most typically a pair of trousers or a shirt.

[0037] In the embodiment shown, the device 2 used to apply the resin includes a fluid transfer means in the form of a source of pressurized gas, e.g. air, an air pump 36 connected to a control means 38, which in this embodiment may be provided as a manually operated switch located on the mounting means 40. Air is supplied to the end 30 of the cartridge 16 via an air tube 34, which is connected to the air pump 36 via an air tube 35. The size and design of the cartridge may vary to suit a particular use. The air pump can be switched on and off, so that control of the supply of pressurized air is achieved via a switch 38 connected to the tubes 34 and 35. The pressurized air leaving the air pump is transferred to the inlet opening 30 of the cartridge 16. The cartridge 16 includes a body 28 in which there is a reservoir for the fluid resin defined therein and connected to an outlet opening. A piston 10 is provided to move along the reservoir, and a quantity of fluid resin material 12 is provided between the piston and the outlet opening 26 of the cartridge. The cartridge body attachment means 40 includes a finger switch 38 for controlling the air pump, which can be grasped by the user when moving the cartridge.

[0038] In this embodiment the cartridge includes guide means 14 at intervals spaced along the length of the cartridge body as shown, which are located along and in contact with the fold line and are located along the same axis as the elongated outlet opening 26 of the cartridge. The guide means are provided to receive and pass along the fold line of the surface of the garment which faces the body of the wearer when the garment is worn, such that the guide means moves along the fold line to guide the cartridge during application of resin along the base 5 of the substantially V-shaped fold line. The fold line lies in a V-shaped or gull-wing shaped groove 4 provided in a support surface or arm 20 which, with its exposed base 5, acts to maintain the fold line along the required linear path and the cartridge moves along the inner surface of the garment in the direction of arrow 18, and as relative movement between the garment and the cartridge occurs, operation of the air pump moves the piston 10 along the cartridge reservoir, causing the resin material 12 to move as a line or ribbon of resin material along the base 5 of the fold line 6 towards and through the outlet opening 26 from which it is dispensed.

[0039] In another form of apparatus, the resin may be fed from a reservoir of resin to an outlet opening 26 provided in a holding means, the holding means being physically separate from the reservoir as shown in FIG.

[0040] In Fig. 2 an alternative embodiment of the device is illustrated and for ease of reference the same reference numerals are used for the same equipment as in the embodiment shown in Figs. la and lb. The application of resin material is also applied along the garment fold line 6 in a similar manner as shown in Fig. la, but in this embodiment no cartridge is provided and instead a reservoir 44 is formed by a drum or container 42 containing the resin material. The reservoir is connected via tubes 48, 50 and via a pump 46 to an application means 52 which includes mounting means including a gripper or holding portion 54 including guiding means in the form of skis or skids or wheels 56. The tube is connected to an outlet opening 26 through which it is dispensed along the base of the fold 6 of the garment 8 as previously described, the fold and the garment being placed on a groove and a support table 58 or support arm 20 similar to that shown in the embodiment of Figs. la and lb.

[0041] In either embodiment, when the resin is dispensed from the outlet opening, it is still in a fluid state and therefore flows from the outlet opening 26 into and along the fold lines.

[0042] When the resin material is applied to the garment fabric along the base of the fold line, and typically passes at least partially therethrough, exposure of the resin to moisture in the surrounding environment, particularly the ambient environment, which is most typically a factory or industrial space, activates a catalyst contained within the resin, causing the resin to begin to cure and harden, and as it does so, bonds to the fibers of the garment fabric adjacent to and along the fold line 6 of the garment 8, and when hardened and bonded, retains the V-shaped configuration of the fold line 6, thereby ensuring that when the resin material is applied precisely to the base 5 of the fold line 6, the resin assists in maintaining the fold configuration in the garment for a longer period of time than if the resin was not applied to the fold line.

[0043] In accordance with the present invention, the resin material 12 is provided with a catalyst in the form of any or any combination of platinum, peroxides, organic amines, titanium, zirconium, tertiary amines, organosilanes, iron, copper and / or non-metals, and is responsive to exposure to the surrounding environment, and in particular to environmental moisture.

[0044] However, to further facilitate a relatively fast curing effect or when changing the curing agent in the resin, the resin application apparatus can include apparatus for, for example, providing heat or subjecting the resin to infrared or ultraviolet light or other curing effects to cure or improve the cure of the resin once it has been applied. An example of an apparatus for achieving this is provided in Figure 2, which illustrates a unit 60 positioned above the garment 8 where the resin has already been applied, which can then emit a curing means, for example heat or a suitable light, onto the resin wire to cure it.

[0045] Platinum-containing catalysts effectively initiate crosslinking of the silicone polymers provided in the resin, achieving the required speed of cure, and are found to be safer and more environmentally friendly than tin-containing resins.

[0046] Peroxide-containing catalysts are effective when used with the silicones contained in the resins according to the invention, initiating the curing process via a free radical mechanism, and can be used in relatively high temperature application procedures and still provide good cure performance.

[0047] Organic amine catalysts are effective when used with silicones contained in the resin and accelerate the cure of the resin by initiating the condensation of silanol groups when exposed to moisture. Organic amine catalysts achieve the required cure speed for the resins to which they are applied that allow them to form and hold creases in the garments.

[0048] Titanium-containing catalysts can be used in the resin, one example being titanium chelates, which achieve good cure rates and are generally considered safe and have low toxicity.

[0049] Zirconium compounds, such as zirconium acetylacetonate, can be used as catalysts in silicone-containing resins to accelerate the curing process, provide good adhesion to the fabric fibers and durability in maintaining creases, and have good stability and resistance to water and other chemicals.

[0050] Tertiary amine catalysts, such as triethylenediamine (TEDA), are effective in accelerating the curing reaction and can therefore be used as catalysts for the resin.

[0051] The organosilane catalyst can be used as a curing agent for resins, especially silanated polymers endcapped with dimethoxy, trimethoxy or diethoxysilane groups, and also eliminates methanol emissions.

[0052] Iron and / or copper catalysts, such as iron acetylacetonate or iron naphthenate, can be used as catalysts for silicone-containing resins to accelerate the curing reaction and provide good cure rates.

[0053] Non-metallic catalysts can be used as catalysts to initiate the curing process, for example organic salts, such as onium salts, or organic bases, such as guanidine derivatives, to achieve good curing rates.

[0054] Now referring to Figures 3a and 3b, we illustrate the manner in which the resin used has non-sagging to flowing properties. This is found to aid in the application of the resin while ensuring the best possible bond of the resin to the fabric when applied. In Figure 3a, the resin is shown as it is applied from the exit opening 26 to the fold line 6 and to the base 5, typically, as soon as the resin leaves the exit opening and is exposed to the ambient environment, the catalyst in the resin initiates the curing effect of the resin. As shown in Figure 3a, typically, the resin initially has the form of a body or "globule" 62 of resin, where the resin has substantially non-sagging properties. The size of the body 62 and the speed of curing are influenced by the parameters of the size of the exit opening 26, the speed of the movement of the exit opening along the fold line, and the conditions of the ambient environment.

[0055] However, upon or after exposure to the conditions of the surrounding environment as the resin leaves the exit opening 26, the resin properties change to flowable properties, which means that the resin 64 begins to absorb and bond with the fibers 66 of the fabric of the garment 8 adjacent the base 5 of the fold line 6, as illustrated in FIG. 3b. This improves the bonding and retention of the subsequently set, fully cured resin with the fabric, and thus the retention of the shape of the fold line 6. This change in the resin from non-sagging properties to flowable properties, in conjunction with the control of the parameters mentioned above, allows for control of the application of the resin, allowing it to be absorbed into and / or bond with the fabric as it cures and hardens. It is also important to control the degree of absorption so that the resin does not pass to the opposite surface of the fabric and become visible from the outside of the garment when it is worn. Typically, this is achieved by controlling the amount of resin applied, and also by controlling the viscosity of the resin, the speed of relative movement between the garment and the outlet opening as the resin is applied along the crease lines, the rate of hardening of the resin, and the particular type and properties of the garment fabric to which the resin is being applied at that moment.

[0056] In one example, the resin used is colorless, comprises a silicone rubber and one or more of the catalysts as described herein, has a cure speed in the range of 1.5-1.7 mm / d when exposed to ambient conditions at ambient conditions of 23 degrees Celsius and 50% relative humidity, and preferably the line of resin is applied to have a thickness of less than 0.75 mm.

[0057] Thus, in accordance with the present invention, a means is provided for extending the duration of crease retention in garments using resin materials that are environmentally friendly and have reduced potential health effects as hardeners or catalysts used in the resin, and the resin as a whole is substantially free of tin, organotin and any tin compounds, thereby overcoming and avoiding health and safety concerns associated with the use of such materials, while at the same time improving the efficacy of the resin by providing it in the format as described herein.
