The fabric is used in garments, especially shorts, tops and leggings.

Description

Fabric The present invention relates to a fabric comprising neoprene, as well as a method for producing the fabric. The fabric of the present invention is particularly suitable for assisting weight loss.
Many people find it hard to reduce or maintain their body weight. There is therefore a need for products which can help with weight loss and increase the effectiveness of any exercise undertaken.
The present invention provides a fabric comprising neoprene and a mixed metal oxide, wherein said mixed metal oxide comprises aluminium and silicon.
The present invention also provides a method of incorporating a mixed metal oxide comprising aluminium and silicon into a fabric.
In a further aspect of the invention, a use of the fabric of the present invention for the purpose of increasing body temperature and/or increasing energy expenditure and/or assisting weight loss of a wearer of the garment is provided.
Yet a further aspect of the invention provides a method of increasing the body temperature and/or increasing the energy expenditure and/or assisting weight loss of a person, wherein the person wears a garment made of a fabric of the present invention.
The mixed metal oxide preferably further comprises zinc and/or magnesium.
The mixed metal oxide may be in the form of a mixture of silicon oxide (SiC2) and aluminium oxide (A1203), preferably further comprising zinc oxide (ZnC) and/or magnesium oxide (MgC). The mixed metal oxide may be in the form of, or derived from, a mineral. The mineral is preferably a silicate mineral, preferably an aluminosilicate mineral.
The mixed metal oxide used in the present invention is preferably a material which emits far-infrared radiation upon absorption of heat, which is referred to herein as a "far-infrared emitter".
Without wishing to be bound by theory, it is believed that the mixed metal oxide absorbs the heat of the human body and emits far-infrared rays, and that such infrared emission improves blood circulation and increases the body temperature of the wearer of a fabric comprising the mixed metal oxide. As used herein, the term "far-infrared" refers to electromagnetic radiation having a wavelength of at least 4 pm, and up to 1000 pm.
The mixed metal oxide is suitably present in particulate form. The particles may be non-agglomerated or agglomerated or a mixture thereof. The primary particle size is preferably no more than 5 pm, preferably no more than 2 pm. Particle sizes are determined by light scattering (photon correlation spectroscopy). The particles may be prepared by grinding of mineral raw material, according to conventional techniques known in the art. The mixed metal oxide may be prepared in the form of a suspension prior to incorporation into the fabric, for instance prior to mixing with the binder.
The amount of mixed metal oxide in the fabric is preferably in the range of from about 0.1 to about wt%, based on the total weight of the fabric.
The fabric described herein enables the production of garments that assist in increasing energy expenditure and facilitating weight, or inch, loss, as well as increasing the effectiveness of exercise when worn by a user. Without wishing to be bound by theory, it is believed that the neoprene and the mixed metal oxide combine to increase the body temperature of the wearer, which in turn increases the effectiveness of exercise and results in the observed beneficial weight loss effects.
In particular, the neoprene acts as a thermal insulator inhibiting the dissipation of the wearer's body heat, while the mixed metal oxide emits radiation in the far infrared region of the electromagnetic spectrum, contributing to the heating effect. It has been found that the combination of neoprene and the mixed metal oxide is effective at raising the wearer's body temperature leading to increased perspiration and increased energy expenditure helping the wearer to reduce body weight.
Neoprene, also known as polychloroprene, is a synthetic rubber. The neoprene is preferably present as a layer of the fabric. A neoprene layer may have a thickness in the range of 0.5 mm to 2.5 mm, preferably in the range of 1 mm to 1.5 mm. The neoprene layer may be continuous within the fabric, or it may be discontinuous. A continuous neoprene layer increases the overall heat retention properties of the fabric. A discontinuous neoprene layer allows optimisation of the placement of neoprene in the resulting garment.
The fabric of the present invention preferably has a first cover layer. The first cover layer covers and protects the other components of the fabric. The first cover layer is suitably configured so that it is present between the other fabric components and the user's body when the fabric is incorporated into a garment. The cover layer allows adjustment of the comfort of the fabric experienced by the wearer independent of the other components. The first cover layer is preferably in a 4-way stretch knit. The first cover layer preferably comprises nylon and/or polyester, and in a preferred embodiment nylon and polyester, which provides a durable and comfortable first cover layer.
The first cover layer preferably has a fabric weight in the range of 100 to 300 g/m2.
The fabric preferably also comprises a second cover layer. The presence of a second cover layer provides additional protection to the other components of the fabric. The second cover layer is suitably configured so that it is present as the outer surface of garment made from the fabric.
Thus, the first second cover layer can be used as a means for adjusting the outward appearance of the garment and protecting the other fabric components from the environment. The second cover layer preferably comprises nylon and/or polyester, and in a preferred embodiment nylon and polyester.
The details described herein with respect to the first cover layer are equally applicable to the second cover layer.
The neoprene is preferably positioned between the first cover layer and the second cover layer.
This enables protection of the neoprene layer which helps maintain the effectiveness of the fabric in enhancing weight loss.
It is preferred that the mixed metal oxide is positioned between the first cover layer and the second cover layer. This enables protection of the mixed metal oxides that contribute to the heating effect of the fabric.
The fabric preferably also comprises one or more binder layer(s). The binder layer facilitates the joining of the various components of the fabric together to form a laminate. A first binder layer may be situated between the first cover layer and the neoprene layer. A second binder layer may be situated between the second cover layer and the neoprene layer. The binder(s) of the first and second binder layer may be the same or different.
The binder layer is preferably a layer of adhesive. Any neoprene-bondable adhesive suitable for use as a fabric or textile adhesive, as known in the art, may be used. Suitable adhesives comprise curable adhesive, for instant UV-curable and thermally curable adhesives.
The mixed metal oxide is preferably present in one or more of the binder layer(s), preferably at least the first binder layer. The second binder layer may also comprise a mixed metal oxide, but preferably the mixed metal oxide is present only in the first binder layer. As noted above, the first cover layer preferably forms the inner surface of the garment and the second cover layer forms the outer surface of the garment. In this manner, the mixed metal oxide particles in the first binder layer, which contribute to the heating effect, are positioned closer to the wearer's body.
Preferably, particles of the mixed metal oxide are distributed throughout a binder layer.
Incorporating the mixed metal oxide into the binder layer reduces the possibility that the mixed metal oxide will be lost from the fabric during normal wear and washing of the fabric.
The mixed metal oxide may form from 2% to 20% of the binder layer by weight. Preferably, the mixed metal oxide forms from 2% to 15% of the binder layer by weight.
A particularly preferred configuration of the fabric is to have a first cover layer of nylon and polyester, a second cover layer of nylon and polyester, a neoprene layer, and the mixed metal oxide in a binder layer. A preferred laminate structure for the fabric is: (i) a first cover layer comprising nylon and/or polyester, (U) a second cover layer comprising nylon and/or polyester, (Hi) a neoprene layer, (iv) a first binder layer between the first cover layer and the neoprene layer; (v) a second binder layer between the second cover layer and the neoprene layer; wherein the mixed metal oxide is present in the first binder layer.
The fabric may further comprise other components, for instance other silicate or aluminosilicate minerals, particularly those which emit radiation in the far infrared region of the electromagnetic spectrum. One such component is tourmaline. Tourmaline is a crystal boron silicate mineral, which further contributes to the heating effect of the fabric.
The present invention also provides to a garment made, at least partly, from the fabric of the invention. Such a garment provides the wearer with the beneficial effects described herein.
The proportion of the garment that incorporates the fabric described herein will dictate the properties of the final garment. The garment could be formed completely of the fabric described herein, thereby increasing the heating effect of the garment. Alternatively, the garment may be only partly formed of the fabric described herein, allowing the quantum of the beneficial effects provided by the fabric to be varied as desired. In particular, it would enable targeted heating of particular body pads.
The beneficial effects of the garment are heightened during exercise. Therefore, it is preferred that the garment is suitable for wearing during a form of exercise.
The garment also offers beneficial effects when worn immediately after exercise during recovery.
Therefore, the gaiment may be woin during exercise andloi immediately aftei exercise.
The garment may be in the form of a pair of shorts, a top (long-sleeved or short-sleeved), a hooded top, a vest, a pair of capri leggings, or a pair of leggings. The range of garments allows various body parts to be covered by the fabric described herein and so enables targeting of the beneficial effects associated with wearing the fabiic of the present invention. Covering a gleater pioportion of the user's body increases the beneficial effects provided by the garment. For example, leggings provide a greater effect relative to shorts.
In forming the fabric, the mixed metal oxide may be mixed with a binder to foim a binder layei, which in turn is applied to the neoprene layer. The first cover layer may be applied to a first binder layer. The second cover layer can be adhered to the neoprene layer via a second binder layer.
The mixed metal oxide may be coated onto any of the other components of the fabric. This could be achieved by dip-coating the fabric component in a suspension of the mixed metal oxide.
The invention will now be described with reference to the following drawings.

EXAMPLES
The mixed metal oxide was Ceramond SAM (available from Wuxi Daintex Co. Ltd), in the form of a suspension of metal oxides and exhibited a white milky colour.
Analysis of the powder contained in the suspension was carried out prior to its incorporation into the fabric using energy dispersive x-ray spectroscopy (EDX). EDX was performed with an acquisition time of 120 seconds and an accelerating voltage of 15 kV. The analysis showed that aluminium, silicon and zinc were present in a weight ratio of 12.4 77.6 10.0, respectively.
Particle size of the Ceramond SAM was determined by light scattering (photon correlation spectroscopy) at 25°C using a run time of 200 seconds. The mean particle size was determined to be 1753.5 nanometres with a standard deviation of 874.00 nanometres.
The effectiveness of the resulting shorts (denoted HP garment hereafter) in facilitating weight loss was determined by a study that compared them with a control garment. The control garment was a pair of conventional exercise shorts of the prior art.
It was found that wearing the HP garment during exercise results in a 11.3% increase in energy expenditure compared to wearing the control garment and a 12.5% increase in energy expenditure compared to wearing the control garment for 30 mm to 1 hour after exercise, if they are on during resting recovery. Following the period of exercise wearing the HP garment there was a 10.6% increase in core temperature and a 4% increase in thigh temperature. The change in weight following exercise while wearing the HP garment is twice that for the control garment: 0.6kg compared to 0.3kg.
The foregoing describes particular embodiments of the invention. However, the scope of the present invention is defined by the following claims.
