Description

Technical Field

[0001] This invention relates to the field of garment processing technology, and in particular to an adjustable thermal inflatable liner and a processing technology for using the liner in clothing. Background Technology

[0002] Currently, multi-functional waterproof jackets have become the mainstream for outdoor activities. Outdoor clothing needs to be warm, waterproof, and lightweight. The inner lining of waterproof jackets is generally made of down, and some brands also have inflatable inner linings.

[0003] The inflatable inner liner is made of a closed-cell membrane material, typically TPU, PVC, or composite materials. When inflated, it forms an array of sealed air chambers, locking in air and creating an insulation layer. The thickness of this air layer can be actively adjusted by the amount of air inflated; the greater the inflation, the thicker the air chambers, the higher the thermal resistance, and the stronger the insulation. The inflatable inner liner is lightweight, portable, and offers adjustable insulation.

[0004] Inflatable liner can be inflated manually (by blowing air or using a mini hand pump) or electrically (using a mini lithium pump with temperature control or pressure sensor to automatically maintain pressure). Some models also have valve components to prevent overcharging and bursting.

[0005] Rain jackets with inflatable linings are suitable for activities such as mountaineering, skiing, and cycling, and can cope with changeable weather. They can also be used for daily commuting after being deflated. Existing multi-functional rain jackets have inflatable linings that are sewn to the edge of the inner wall of the garment. When the lining is inflated, it expands and the edge bends. The sewn points pull on the inner wall of the garment, resulting in wrinkles and deformation on the outside.

[0006] This method of sewing the inner lining is not breathable. In certain environments, such as skiing, a certain degree of breathability is required when keeping warm, and a completely sealed inner lining cannot dissipate heat.

[0007] Existing inflatable liner types have relatively high production costs because their specifications need to be consistent with those of clothing. The same type of liner cannot be adapted to clothing of different sizes. Summary of the Invention

[0008] Based on this, it is necessary to address the issues raised above by providing an adjustable inflatable liner with thermal insulation properties and its processing technology for use in clothing. The liner adjusts its thermal insulation performance by inflating and deflating the air volume. This type of liner is suitable for various sizes of clothing, has good breathability, and prevents the outer garment from deforming after inflation.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an adjustable inflatable liner with heat retention, formed by two layers of fabric and two layers of air-sealed membrane, with a collar and cuffs, and the inner cavity is inflated and deflated through an inflation / deflation port. The inflatable liner has evenly or unevenly distributed (as needed) inner cavity connection points, and the edge of the inflatable liner is provided with multiple sets of elastic bands.

[0010] In a preferred embodiment, the present invention may be further configured such that a vent hole is provided at the inner cavity connection point.

[0011] By adopting the above technical solution, the air permeability of the inflatable inner liner is improved, and the air permeability is uniform.

[0012] In a preferred embodiment, the present invention can be further configured such that the maximum air pressure inside the inflatable liner is set according to actual needs, preferably 300 Pa.

[0013] This is achieved through an electric air pump. When the set air pressure (e.g., 300 Pa) is reached, the built-in sensor will transmit a signal and stop the inflation. By adopting the above technical solution, the internal pressure of the inflatable liner will not be too high after inflation.

[0014] The shape of the internal cavity connection point is set according to actual needs.

[0015] In a preferred embodiment, the present invention can be further configured such that: the inner cavity connection points are circular, every four inner cavity connection points form a unit, and the inner cavity connection points of each unit are distributed in a parallelogram.

[0016] The above technical solution is applied to an inflatable inner liner with a thickness of 17mm when the inner cavity pressure is 300pa.

[0017] In a preferred embodiment, the present invention can be further configured such that: the inner cavity connection points are elongated, each unit consists of four inner cavity connection points, the inner cavity connection points of each unit are distributed in a square, and two adjacent inner cavity connection points are perpendicular to each other.

[0018] The above technical solution is applied to an inflatable inner liner with a thickness of 35mm when the inner cavity pressure is 300pa.

[0019] In a preferred embodiment, the present invention can be further configured such that: the inner cavity connection points are circular, every four inner cavity connection points form a unit, and the inner cavity connection points of each unit are distributed in a square.

[0020] The above technical solution is applied to an inflatable inner liner with a thickness of 52mm when the inner cavity pressure is 300pa.

[0021] The processing technology of the inflatable inner liner in clothing is as follows: The inflatable inner liner is placed on the inner wall of the garment, and its edge is connected to the inner wall of the garment by multiple sets of elastic bands. The two ends of the elastic bands are respectively connected to the edge sealing of the inflatable inner liner and the inner wall of the garment. The garment has ventilation holes in the armpits and back where sweat is easy to get, and multiple sets of elastic bands are provided and evenly distributed on the edge of the inner liner.

[0022] In summary, the present invention has at least one of the following beneficial technical effects:

[0023] 1. The inflatable inner liner is connected to the clothing by an elastic band. After inflation, the elasticity of the connection point prevents the outer garment from deforming.

[0024] 2. The inflatable liner is connected to the clothing with elasticity. When the inflatable liner is of the same size, it can be adapted to different sizes of outer garments, reducing the production of inflatable liner of different sizes and saving costs.

[0025] 3. Perforations are made at the connection points of the inflatable inner liner to make it breathable. At the same time, it is connected to the outer garment with elastic bands, and the gap between the inner liner and the outer garment also has a breathable effect, making it suitable for skiing, hiking and other scenarios.

[0026] 4. By designing the connection points between the inner cavities of the inflatable inner liner, the inner cavities of the inflatable inner liner can have different thicknesses under the same air pressure, making it suitable for a wide range of scenarios and achieving different heat preservation effects.
