Description

Filling material capable of absorbing moisture, releasing moisture and adjusting temperature

Technical Field

The invention relates to a filling material capable of absorbing and dehumidifying to adjust temperature, and belongs to the technical field of textile materials.

Background

A wide variety of natural and synthetic filling materials for down jackets, sleeping bags and duvets are known. Natural down is widely used in people's daily life because of its excellent heat weight efficiency, softness, resilience, washing durability and shakeability. The stereo spherical structure of the down feather, a large number of radial down feather threads, and thousands of hollow scales and hollow joints of the down feather threads can fix a large amount of air, prevent the heat of a human body from dissipating, and play a role in excellent warm keeping and heat preservation, so that the down feather is generally considered as the best heat preservation material.

However, when the environmental humidity is high, the natural down is exposed to the moisture, and the down absorbs too much moisture, so that the down has radial down threads, thousands of hollow scales and hollow joints which are intertwined with each other, and the stereo spherical structure of the down collapses and agglomerates, thereby losing the thermal insulation and heat preservation performance.

In addition, many people are allergic to natural down, resulting in a great limitation in the range of applications of natural down. The down feather is a natural material, can emit rather unpleasant odor, cannot be industrially produced, is high in cost and unstable in source, is easily influenced by factors such as animal epidemic diseases, and is easy to cause water pollution and infectious diseases caused by excrement of aquatic birds if a large amount of down feather is obtained by raising the poultry. Meanwhile, in europe and the like, there has also been a movement to abolish feathers as a filling material from the viewpoint of animal protection.

The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments. It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict.

In this application, where the contrary is not intended, directional words such as "upper, lower, top and bottom" are generally used with respect to the orientation shown in the drawings, or with respect to the component itself in the vertical, vertical or gravitational direction; likewise, for ease of understanding and description, "inner and outer" refer to the inner and outer relative to the profile of the components themselves, but the above directional words are not intended to limit the application.

Referring to fig. 1, a filling material capable of absorbing and releasing moisture to adjust temperature includes a plurality of fiber balls, the fiber balls include a plurality of moisture-absorbing and heat-generating fibers and load-bearing fibers of different shapes and sizes, and the moisture-absorbing and heat-generating fibers of different shapes and sizes and the load-bearing fibers of different shapes and sizes are randomly arranged and intertwined in the fiber balls, so that the fiber balls are substantially spherical or elliptical. Wherein the average diameter of the fiber ball is 4-12mm, the preferred average diameter is 6-10mm, the crimp shape of the hygroscopic heating fiber is two-dimensional mechanical crimp, the number of crimps is 4-12/25 mm, the crimp shape of the carrier fiber is three-dimensional hollow crimp and/or two-dimensional mechanical crimp, and the number of crimps is 6-15/25 mm.

Particularly, the moisture absorption heating fibers and the bearing fibers are short fibers, and the bearing fibers are non-moisture absorption fibers. The wet-absorbable and heat-generating short fibers in various sizes and shapes and the bearing short fibers in various shapes and sizes are randomly arranged and intertwined, so that the ends of the wet-absorbable and heat-generating short fibers and the bearing short fibers in various shapes and sizes are randomly arranged, the structure of the fiber ball is similar to the structure of down feather which is provided with thousands of hollow scales and hollow joint down feather filaments, the fluffy degree, the softness and the heat preservation of the down feather can be simulated, and the down feather can absorb moisture, generate heat or absorb moisture and heat to adjust the temperature.

Specifically, the moisture-absorbing and heat-generating fibers are selected from but not limited to cellulose fibers, natural cotton, wool fibers and cuprammonium fibers, the cellulose fibers can be specifically viscose fibers or modified acrylic fibers, and the carrier fibers are selected from but not limited to silicon-added polyester fibers. Are all conventional materials and are not described herein. Wherein, the proportion ratio of the moisture absorption heating fiber is 5-60%, the preferential proportion is 8-30%, and the proportion of the bearing fiber is 40-95%, the preferential proportion is 60-80%.

When the ratio of the hygroscopic heat-generating fibers is less than the above range, the load-bearing fibers are higher than the above range, the hygroscopic heat-generating fibers cannot sufficiently exhibit hygroscopic heat generation and hygroscopic heat-releasing property, and the sucked moist air cannot sufficiently change to warm air with low humidity. When the hygroscopic exothermic fiber exceeds the above range, it is not good in economical efficiency, and at the same time, the carrier fiber is lower than the above range, and the hygroscopic exothermic fiber collapses and lumps due to the absorption of humid air, which is not good for maintaining the bulkiness of the filling material.

The filling material composed of the fiber balls has the filling power of 450-700in3/30g, the rebound resilience of 60-98% and the heat preservation rate of 50-98%. Because the bearing fiber is the non-hygroscopic fiber, when in a humid environment, the hygroscopic heating fiber absorbs moisture, and the bearing fiber does not absorb moisture, so that the bearing fiber can keep higher bulkiness, collapse caused by excessive moisture absorption can be avoided, and the skin of a user can not feel stuffy and humid. Simultaneously, the filling material of this application is difficult for agglomerating because of the pressurized in the use, appears hardening phenomenon after this filling material washes, and accessible shake, pat so that the fibre ball in this filling material resumes fluffy state under the elastic recovery effect.

The moisture absorption and heat generation principle of the moisture absorption and heat generation fiber is as follows: when water vapor molecules with high kinetic energy emitted from a user body or existing in the air are combined with hydrophilic groups in the moisture absorption heating fibers, the water vapor molecules are adsorbed and are static, and according to the energy conservation theorem, on the premise that the potential energy of the water vapor molecules is not changed, the kinetic energy of the water vapor molecules is converted into heat to be released, namely the water molecules are converted from gas into liquid to release heat.

On the contrary, the moisture releasing and heat absorbing principle of the moisture absorbing and heat emitting fiber is as follows: when the ambient temperature is too high, the liquid vapor molecules attached to the surface of the moisture absorption heating fibers are converted into gas from liquid, and according to the law of energy conservation, the vapor molecules absorb heat and convert the heat into kinetic energy when the liquid is converted into the gas, so that the heat absorption effect is achieved.

As is well known, the heat generating performance of the moisture absorption and heat generation fiber is related to the moisture regain, and the moisture regain is high, so that the moisture absorption and heat generation performance is excellent. In this embodiment, the official moisture regain of the moisture-absorbing and heat-generating fiber is greater than or equal to 6%, the maximum temperature rise of the moisture-absorbing and heat-generating fiber is 1-8 ℃, and the moisture regain of the load-bearing fiber is less than 1%.

Hydrophilic softening agent is attached to the surface of the moisture-absorbing and heat-generating fiber. The hydrophilic softening agent can keep or improve the hydrophilic characteristic of the moisture-absorbing heating fibers so as to enhance the moisture-absorbing heating effect of the moisture-absorbing heating fibers and further enhance the heat preservation effect. For the conventional arrangement, it is not described herein.
