Technical Fields

Invention relates to textile heating garment, especially for relief of menstrual pain or other pains in the lower abdomen and back region.

Background Arts

Many embodiments are known for heating specific body parts, especially if used for pain relief or better blood flow to the given area due to stiffness, stress or cold. The most basic is applying heated items, be it heated stones or applying heating pad filled with warm water. Instant gel thermal bags or bags filled with seeds, wheat etc. are also known. Those solutions are portable, but without the possibility of temperature regulation. In the same time those solutions are single use only, as they do not work without repeated heating of the medium (refilling with warm water, heating the contents of the bag in a microwave oven) or without reactivation by cooking as is the case with gel bags. The problem of those solutions is also the need to hold them onto specific parts of the body, i.e. the need to hold them or apply lay mechanical fixation at the site of action.

Also known are various electric heating mats. The disadvantage of all these aids is they are not portable and so the person cannot have them on their body while moving. Those solutions are proposed only for use on front or back part of body and they do not address complex warming of the middle section of the body, i.e. warming of both lower abdomen and lower back area in the same time. Also known is electrical heated yarn in accordance with WO2017111687A1, which is used to knit textile garment which is put on body where it stays even in movement. Such solution is expensive and problematic when washing. It is textile yarn which is woven together with electrically heated filament.

Technical solutions that are not based on heating are also used to eliminate pain, especially menstrual pain. It is, for example, TENS - transcutaneous electrical nerve stimulation, which is the application of electric current, which agitates nerve trunks and nerve fibers leading to pain relief. Those are the low-energy pulses (frequency 1 to 200 Hz) produced by low-frequency oscillator. Impulses send by oscillator can have different shape and they are shorter than 1 ms (usually 10 to 750 ps). This method of pain relief is not suitable for everyone. Example of contraindication is the presence of pacemaker.

Disclosure of Invention

Mentioned shortcomings are eliminated by the textile heating garment, especially for relief of menstrual pain, in accordance with the present invention, the summary of which is that the garment consists of two identical parts, the front abdominal part of the knitwear and the back part of the knitwear, when both of these parts are equipped with a heating surface consisting of a conductive yam that is covered, and thus attached to the knit, with a lamination layer. Conductive yarn is connected to supply of low- voltage electric current from the battery.

Preferably both abdominal and back part are provided with fixation element for insertion or attachment of battery so it does not arbitrarily tear away from magnetic contact. For improvement of the resulting aesthetic impression both abdomen and back part of knitwear is covered by exposed knitwear. Perimeter of laminating layer, which attaches conductive yarn to both parts of knitwear, is provided with elastic stitches for better fixation to the knitwear.

Advantage of this invention is that it is simple and easy to connect and turn on and it is able to function and be worn even while moving. As part of the main focus of the technical solution, i.e. the removal of menstrual pain, the lower abdomen area and lower back area directed towards the coccyx are specially heated. Heating can be regulated in wide range from 40 to 50 degrees, both directly on the power supply unit or on the supplied mobile application.

Heating surface is formed by conductive yarn or resistive and conductive wires (silver, stainless steel or other conductive materials, gold, copper) provided with protective layer of yarn or resistive and conductive wires, which are sewn with a flexible thread into the laminating material (polyester, Teflon). The entire resulting garment is flexible, stable and elastic on the wearer’s body and it is resistant to approx. 150 to 200 washing cycles without individual layers peeling off. For maximum fixation, it is also equipped with elastic stitches around the laminating layer, especially in its corners and the area around the connector, which are under the most stress and tent do peel off, especially if the product is washed without a laundry bag or dried in a dryer, and other unsparing treatment. Elastic stitches are used primarily for natural-based knitwear. In synthetic fibers or with a higher percentage of synthetic fibers, the adhesive of the lamination layer adheres better and the stitches are not needed. Power supply of heating surface is inconspicuously and aesthetically hidden in the clothing.

Thanks to all of the above, the heat relieves tissue or muscle tension and helps oxygenation and blood flow, ultimately resulting in relief from especially menstrual pain, pain in the lower back or inflammation of the bladder or kidneys.

Workflow - 2-layer women’s bodysuit

First inner parts of knitwear are cut, both abdominal part 1 and back part 2 of knitwear, and they are different for each size. During subsequent lamination shrinking occurs, and for that reason both parts 1 and 2 are enlarged by 5 to 15 %, so the laminated parts can be completed with parts without lamination after the end of lamination. Conductive yarn 6 on heating surface 3 is sewn into an ornament which covers places where the heating is desirable. In order to be able to subsequently laminate the ornament with a laminating layer 4 on the abdominal part 1 and the back part 2 of the viscose-based knitwear, a gap between the conductive yarn 6 of at least 1 cm is recommended. Ideally, 1 to 2 cm to ensure maximum fixation of the individual layers. When sewing the ornament, a thin layer of textile is used as a backing, but this layer is only auxiliary and it is removed after lamination. Stitches which are allowing to wind the conductive yarn 6 into requested shape, disappear with heat and laminating layer 4 then holds requested shape of conductive yarn 6. Then the protective casing is removed from the ends of conductive yarn 6 and magnetic connector - clip for battery 5 connection is attached. Finally, all layers are provided with elastic stitches 9 over the perimeter of laminating layer 4, which is since the moment of conductive yam lamination the same as the extent of heating surface 3.

Abdominal part 1 and back part 2 of knitwear are then completed together and provided with outer layer, i.e. exposed knitwear 8. At the same time the fixation element 7 is added in the form of pocket or Velcro tape or rubber strap.
