[0029] In some embodiments, a printing process may be utilized to apply the composite to fabrics and/or garments, by using one or more textile printing techniques. Additionally or alternatively, the cooling elements or cooling materials or cooling mixture(s) may be applied or added to (or embedded into, or integrated into) a fabric or a garment by utilizing one or more other methods, for example, coating, spraying, padding, foam application, hot melt systems, ultra-violet (UV) curing methods or curable systems, soaking, mixing, gluing, bonding, brushing (e.g., the materials are deposited as a coating being brushed onto a fabric or garment), welding, ultrasonic welding, mechanical connection, inter-weaving, pressure, stitching, sewing, weaving, inter-weaving, bonding elements, or the like.
[0030] Optionally, the cooling element may be manufactured or produced as a stand-alone or autonomous cooling element, which may then be added (e.g., as a sticker or as a patch) by an end-user or by a professional (e.g., a tailor, or a clothes manufacturer) to existing fabric(s) and/or to existing garment(s). In some embodiments, the cooling elements or cooling substances or cooling mixture(s) may be deposited onto or into a fabric or a garment, or may be sprayed or coated or brushed thereon or therein, or may be injected into the fabric or garment, or may otherwise be mixed or added to the fabric or garment.
[0031] In some embodiments, the cooling elements or cooling substances or cooling mixture(s) may be inserted into an internal layer of a fabric or a garment (e.g., as a filling within a layer of the fabric that is "sandwiched" or trapped between two or more other layers, and which does not directly touch the human body, and does not directly touch the air or environment that surrounds the external side of the garment or fabric). In some embodiments, the cooling elements or cooling substance(s) or cooling mixture(s) may be deposited or added or coated by utilizing ribs, rims, protrusions, craters, tunnels, channels, rail-shaped elements, dots, linear elements, or other suitable three-dimensional or two- dimensional elements that may be deposited on or within or under a layer of fabric. Other suitable deposition or coating or connection or integration methods may be used.
[0032] In some embodiments, the materials may be applied to, or printed on, or woven onto, or otherwise integrated into: (a) only the external side or the external surface of the fabric or garment, which does not directly touch the skin of the wearer; (b) only the internal side or the internal surface of the fabric or the garment, which directly touches the skin of the wearer; (c) both the internal and external sides or the fabric or garment; (d) only a middle layer of the fabric or garment, which neither directly touches the skin of the wearer, nor is it directly exposed to air or environment; (e) only a single layer of fabric, if the fabric is made of two- or-more layers; (f) all the layers of a fabric, if the fabric is made of two-or-more layers; (g) only some, and not all, of the layers of a fabric that is formed of multiple layers; (h) only a single layer of a fabric that is formed of multiple layers. Other suitable deposition methods or regions may be used, in order to achieve desired results of cooling effect(s) in different regions of a fabric or a garment, or in different types of garments.
[0033] In a demonstrative embodiment, a printing process may be utilized to deposit 5% to 80% (or 10% to 70%; or 20% to 60%; or 30% to 60%; or 33% to 67%; or 40% to 60%; or 40% to 51%; or at least 51%) solids add-on on the fabric surface (or garment, or garment- region) in a pre-defined pattern or open pattern.
[0034] Reference is made to Fig. 1, which is a schematic illustration of a front-side of a shirt 100, in accordance with some demonstrative embodiments of the present invention. In shirt 100, the left sleeve 131 may comprise an active-cooling region 141, in which cooling material(s) are integrated into the fabric. Similarly, the right sleeve 132 may comprise an active-cooling region 142, in which cooling material(s) are integrated into the fabric. Optionally, the chest area 133 of shirt 100 may comprise an active-cooling region 144, in which the cooling material(s) are integrated into the fabric. Other regions or areas of shirt 100, such as the stomach area 135, lack or do not contain any cooling material(s) therein or in their fabric.
[0035] Reference is made to Fig. 2, which is a schematic illustration of a fabric 200, in accordance with some demonstrative embodiments of the present invention. Fabric 200 may be utilized for manufacturing of shirts and other suitable garments or clothes. In fabric 200, some particular areas 201 and 202 comprise cooling material(s); whereas other areas (such as areas 203 and 204) of fabric 200 lack or do not contain any cooling material(s). Fabric 200 may enable to manufacture a garment in which particular regions or areas are selectively cooled by the cooling substance(s); whereas other garment areas or garment regions are not. [0036] Reference is made to Fig. 3, which is a schematic illustration of a set of several deposition patterns 301-307 of cooling elements or cooling substances, in accordance with some embodiments of the present invention. In deposition patterns 301-307, the black lines or black elements (e.g., circles, hollow circles, filled circles, boxes, filled boxes, hollow boxes, triangles, hollow triangles, filled triangles, or the like) indicate deposition of cooling material(s) into or onto a fabric or a garment; whereas, areas that are white indicate regions of the fabric or garment that does not contain cooling material(s), or regions of the fabric or garment into which (or onto which) cooling materials are not deposited. In some embodiments, active cooling material(s) may be deposited or integrated or embedded, on or in or into the garment or the fabric, in a selective automated manner, and/or using repetitive pattern(s), or using non-repetitive patterns, and/or using pseudo-random patterns or schemes; or by using only filled patterns or shapes, or by using only non-hollow patterns or shapes, or by using only hollow (e.g., circumferential) shapes or patterns; or by using a pre-defined scheme that combines both hollow and non-hollow shapes; or in accordance with a predefined scheme that deposits or creates a first type of active cooling material shape (e.g., only hollow items, or only circumferential items) at a first garment-region and that also creates a second, different, type of active cooling materials shape (e.g., only non-hollow items, or only filled items) at a second, different, garment-region; such schemes and patterns are not merely ornamental, but rather, they are functional patterns that in accordance with the present invention achieve a particular active cooling function of a fabric or of a garment or of (or at) particular garment region(s), or that enable a first garment-region to have a first, increased, level of active cooling functionality (e.g., using higher density of patterns, or using filled and non-hollow patterns), while also enabling a second garment-region of the same garment to have a second (e.g., reduced) level of active cooling (e.g., by using lower density of patterns, or by using non-filled and hollow patterns) or to lack active cooling entirely (e.g., by avoiding or skipping deposition of active cooling materials at a certain region). Deposition patterns 301-307 are only some demonstrative non-limiting examples of deposition patterns of cooling elements or cooling substance(s), in accordance with some embodiments of the present invention; and other suitable patterns or structures may be used.
[0037] In some embodiments, the pattern and/or each cooling element may be a generally continuous array or matrix; a symmetrical pattern; a rectangular pattern; a square-pattern; a perfect polygon pattern; a circular or circle pattern; an oval; a triangle; a zigzag pattern; a dove-tail pattern; or the like. In other embodiments, the pattern and/or each cooling element may be a generally dis-continuous pattern; a non-symmetrical pattern; "U" shaped; "n" shaped; "L" shaped; "X" shaped; or the like. Other suitable shapes or patterns may be used, for the entire deposited pattern, and/or for each particular and/or discrete cooling element or cooling region by itself.
[0038] In some embodiments, the coverage of deposited materials (or otherwise integrated active-cooling materials) on the fabric or garment may be, for example, in the range of 1% to 66% of the fabric surface (or the garment surface); or in the range of 3% to 51%; or in the range of 5% to 50%; or in the range of 5% to 49%; or in the range of 10% to 40%; or in the range of 10% to 33%; or in the range of 15% to 25%.
[0039] In some embodiments, the dry-weight add-on of the deposited material(s) may be, for example, in the range of 10 to 200 gr/m 2 ; or in the range of 20 to 150 gr/m 2 ; or in the range of
40 to 120 gr/m 2 ; or in the range of 50 to 100 gr/m 2. Other suitable ranges may be used.
[0040] Optionally, after the printing or coating or deposition, the fabric or garment may be cured; for example, by using a curing element or heating element producing heat in the range of 120 to 180 degrees Celsius; for a period of 1 to 10 minutes, or a period of 3 to 7 minutes. Other suitable temperatures may be used, and other heating time -periods may be used.

[0060] It is noted that the various ratios, percentage values, quantities, and materials, are not merely random or arbitrary values or ranges; but rather, they reflect particular values or ranges that the Applicants have experimented with and hand-picked and selected, and/or have realized that they are beneficial or advantageous to various garments or fabrics.
[0061] Reference is made to Figs. 4A and 4B, which are schematic illustrations of three diagrams 401-403 which may be used for selective deposition (or selective integration, or selective embedding) of cooling materials onto (or onto) a garment, in accordance with some demonstrative embodiments of the present invention. Diagram 401 demonstrates the anterior of a human; diagram 402 demonstrates the posterior of a human; and diagram 403 demonstrates a Swear Rate Chart which may be used for selecting in which regions of the garment to deposit the active cooling material(s), and/or to determine in which regions of the garment the deposition should exist or should not exist or should be intensified or should be diluted, and/or to determine which regions of the garment should have increased or crowded depositions (or conversely, no depositions, or few depositions per area, or less-crowded or more- scattered depositions). The sweat rate values (or ranges) are shown, for demonstrative purposes, in units of: grams per meter-square of body surface area per hour; or "g / (m h)"; or "g m"2 h"1"; however, other suitable units may be used to indicate sweat rate or swear production or sweat accumulation, which in turn may be used for determining garment- regions that should include or exclude active cooling substances, and/or which may be used for determining density of intensity of deposition (or integration, or embedding) or active cooling material(s) onto or into garment-regions.
[0062] In a demonstrative implementation, for example, upper-back area has the greatest sweat rate (values of 1197 and 840); the central-back and lower-back areas have an increased sweat rate (values of 1148, 856, and 750 or 742); the front-shoulders and back-shoulders area have an increased sweat rate (values of 656), as so does the neck area (value of 622); and the front chest area has sweat rate of 546 and 498;whereas the arms, hands, legs, hips, and other body parts have other, less significant, sweat areas.

[0064] In some embodiments, active cooling materials are deposited on, or integrated or embedded in or within, only garment-regions that have a sweat rate that is greater than K; whereas other garment-regions lack (or, are devoid of) such active cooling materials.
[0065] In some embodiments, active cooling materials are deposited on, or integrated or embedded in or within, only garment-regions that have a sweat rate that is within a predefined range of values; whereas other garment-regions lack (or, are devoid of) such active cooling materials.
[0066] In some embodiments, active cooling material(s) are deposited in a first intensity or density or concentration or quantity or crowdedness-level or deposited-patterns-per-area in a first garment-region that has a first sweat rate (Kl); and, active cooling material(s) are deposited in a second, lower, intensity or density or quantity or concentration or crowdedness-level or deposited-patterns-per-area in a second garment-region that has a second sweat rate (K2) that is smaller than the first sweat rate (Kl).
[0067] In some embodiments, the greater the sweat rate value, the higher the intensity or density or quantity or concentration or crowdedness-level or deposited-patterns-per-area of the active cooling material(s) in the corresponding garment region; and, the smaller the sweat rate value, the smaller the intensity or density or quantity or concentration or crowdedness- level or deposited-patterns-per-area of the active cooling material(s) in the corresponding garment region.
