Description

INNER CLOTH FOR ABSORBER LIQUIDS

TECHNICAL FIELD OF THE INVENTION The present invention relates to the technical field of the textile industry and more specific to the clothing industry as it provides a garment for retaining and absorbing liquids. BACKGROUND OF THE INVENTION

For various factors, for example, menstruation and urinary continence, to name a few, devices and garments have been developed that have the ability to retain and absorb fluids, so that the person wearing these garments does not suffer from stains or they get wet due to the flow of liquids.

The great advantage of this type of garments is that they are designed so that people can wear a built-in absorbent, thus offering a lot of security.

Normally, these garments replace normal underwear, and can be washed and reused day after day, saving us a lot of money in the purchase of absorbents such as compresses or diapers. In addition, for people suffering from loss of urine or women during their menstrual period, it is beneficial to normalize their underwear that guarantees comfort, fashion, protection and safety.

These types of garments are discreet and it is not noticed that they wear absorbent layers normalizing the situation of insecurity that a person with incontinence or a woman may have during their menstrual period. For children they are garments that normalize their situation in the classroom and among other children, avoiding the use of diapers or that the absorbents take over the pants. Shameful situations are thus minimized by facilitating school inclusion for teachers and educational counselors.

Menstruation towels are well known in the art and are widely used in their variations as disposable towels with wings and cloth towels. Currently the disposable towel

it has an adhesive to hold the product to the underwear and in the case of cloth towels it must be attached to the underwear by means of a clasp; Both methods are ineffective to keep the product fixed to the intimate garment since when walking or lying down said product moves which causes menstrual blood leaks and stains on the clothes. Also these products cause irritations, vaginal infections, urinary tract infections due to the materials from which they are manufactured and are uncomfortable to use when they are shaped like a lump.

A technical search of patents for garment to retain and absorb liquids was carried out and it was found that a variety of garments have been developed that fulfill this purpose, as mentioned in the international publication number WO2015039218 (Al), published on March 26, 2015 , with the title "HIGHLY ABSORBABLE RESISTANT, WASHABLE AND REUSABLE INTERIOR GARMENTS, METHODS OF USE, EQUIPMENT AND USES OF THE SAME", said document describes an article of underwear which has a fabric and a layer of fabric for use over a region The pelvic of a person also has a water repellent layer attached to a portion of the crotch; the fabric layer forms an inner chamber and an inner pad disposed within said inner chamber between the water repellent layer and the fabric layer. The inner pad is heat resistant and includes a liquid impermeable layer. The liquid impermeable layer comes into contact with the water repellent layer and is effective to absorb a volume of liquid greater than 2 fluid ounces. The waterproof layer is effective in restricting the liquid from reaching the fabric layer. The crotch portion of the fabric layer and the water repellent layer may be substantially elastic in at least one of a lateral direction and a longitudinal direction of the crotch portion. Methods for wearing underwear, equipment and uses of the undergarment are also described.

In relation to document WO2Q15039218 (Al), even when the garment is provided with a waterproof layer adhered to a layer of fabric in the crotch thus forming an internal chamber within which it has a pad, which is composed of an impermeable layer and a absorbent, the objective of this is that the waterproof fabric layer is in contact with the genital area of the person, however, the garment for retaining and absorbing liquids of the present invention prevents any layer containing absorbent and / or waterproof characteristics have contact with the genital area or skin of the person who is using the garment. Another difference of the invention described in the international publication WO2015039218 (Al), is that it refers exclusively to the configuration of the section that houses the absorbent towel and does not describe that it solves the problem presented by most garments with these characteristics , which is comfort, aesthetics and resistance, does not have an arrangement of different layers of different materials, which give a characteristic of greater absorption and impermeability. Finally, reference is made to the document of the international publication number WO2015156686 (A2), published on October 15, 2015, with the title "ABSORBENT PRESS" which describes absorbent, washable and undergarments for incontinent or similar persons, which They can be of different styles, colors and capacities. An absorbent bag assembly is formed by an inner and permeable layer which is against the skin. A layer of absorbent cotton enclosed by a stretchable textile impermeable to gas and waterproof. The bag is fixed by conventional elastic strips and laminated elastic fabric. Each style is visually similar to a regular underwear style and will reduce shame when used. The absorbent garment has a waterproof treatment using an emulsion of fluoroalkyl acrylate pernealed in a knitted fabric or fabric.

As can be seen in the document described above, the garment is provided with a waterproof section that supports a layer of fabric in the crotch thus forming a section with a pad, allowing the layer of the fabric to be in contact with the skin or the Genital area of the person who uses it, which can cause irritations, vaginal infections, urinary tract infections due to the materials from which they are manufactured and are uncomfortable to use when shaped like a lump.

None of the above documents refers to the fact that, thanks to the components of the garment, it is fresh, resistant, durable, organic, hypoallergenic and especially biodegradable, as well as presenting antibacterial, antifungal and athermal characteristics. OBJECT OF THE INVENTION

The present invention aims to provide a garment for retaining and absorbing liquids, which has an arrangement of various layers of different materials, which give a characteristic of greater absorption and impermeability, said arrangement of layers is configured to allow comfort and aesthetics to the person who uses it, as well as resistance that allows the garment to be washed and dried, in order to be reused several times,
