Description

Technical Field

[0001] The invention relates to the technical field of air permeability detection, in particular to an air permeability detection device for ultra-fine polyester network yarns with high air permeability. Background Art

[0002] The breathability of fabrics is crucial to clothing products, and it directly affects the wearing comfort of clothing. Human skin will continuously produce sweat and heat. If the breathability of clothing fabrics is poor, sweat cannot be effectively discharged and heat cannot be quickly dissipated, which will cause the wearer to feel stuffy and airtight. On the contrary, fabrics with good breathability can allow air to circulate, help sweat evaporate, keep the skin dry, and thus improve wearing comfort.

[0003] Therefore, the air permeability of the fabric is very important and affects the quality of clothing. After the polyester network yarn is woven into the fabric, its air permeability needs to be tested. The air permeability of different positions of the fabric may also be different. Different positions need to be tested during the test. In order to facilitate the improvement of the highly air-permeable ultra-fine polyester network yarn, it is necessary to continuously test the fabric woven therefrom to ensure that the highly air-permeable ultra-fine polyester network yarn has high air permeability. In order to facilitate the intuitive observation of air permeability, as well as the changes in air permeability under the influence of different fabrics, different positions or different thicknesses of fabrics, a permeability detection device that is convenient for detection is proposed based on this.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The present invention provides a technical solution: a highly air-permeable ultra-fine polyester network yarn air permeability detection device, comprising a ventilation box 1 and a ventilation end 3 fixed at its upper end, the ventilation end 3 is connected to an air pump, an observation tube 2 for observing air permeability is also fixed to the outside of the ventilation box 1, and a limiting layer 4 for clamping and limiting the cloth is provided on the other side of the ventilation box 1, the limiting layer 4 comprises a limiting ring 1 42 and a limiting ring 2 44, the limiting ring 1 42 and the limiting ring 2 44 clamp the cloth.

[0024] A glass layer 21 is fixed to the outside of the observation tube 2, which can directly observe the movement of the metal plug 22. The glass layer 21 is used for observation. A metal plug 22 is also slidably provided inside the observation tube 2, and an elastic band 23 is fixed to the inside of the metal plug 22. A connecting hole 25 is opened on one side of the ventilation box 1, and the elastic band 23 extends from the connecting hole 25. A soft plug 24 for sealing is plugged in the connecting hole 25. The elastic band 23 pulls the metal plug 22 so that the movement degree of the metal plug 22 can be directly observed, so that different fabrics can be tested, ensuring that the network yarn is improved to have higher air permeability.

[0025] A limiting ring 42 is fixed on one side of the ventilation box 1, and its interior is connected to the interior of the ventilation box 1. A fastener 43 is also fixed to one side of the ventilation box 1. A limiting ring 44 is sleeved on the outside of the limiting ring 42, and a fastener 45 is fixed to the outside of the limiting ring 44. The fasteners 43 and 45 are matched together. The limiting rings 42 and 44 are used to clamp the fabric, and the matching of the fasteners 43 and 45 facilitates positioning.

[0026] A layer of adsorption member 41 is fixed to the outside of the ventilation box 1. The adsorption member 41 is a magnet. The axis of the adsorption member 41 coincides with the axis of the limiting ring 42. The adsorption member 41 is adsorbed with another layer of adsorption member 41. The two layers of adsorption members 41 are used to limit the cloth. The cloth can be slightly limited in advance, and then the position of the cloth can be locally adjusted to change different positions of the cloth, or different cloths can be stretched to the same degree.

[0027] The limiting ring 1 42 is made of metal, the limiting ring 2 44 is made of rubber, and the outer side of the limiting ring 1 42 fits with the inner side of the limiting ring 2 44 , which can ensure that the cloth is clamped under the action of the limiting ring 2 44 and ensure that the gas can pass through the cloth.

[0028] A clamping cavity 421 is provided on the outside of the limiting ring 42, and a control ring layer 46 is also provided on the outside of the limiting ring 42. The control ring layers 46 are provided with multiple layers from large to small, and are arranged in a ring-shaped manner. A clamping cavity 461 is provided on the outside of the multiple control ring layers 46. The edge of the outermost control ring layer 46 is clamped into the clamping cavity 421, and the remaining control ring layers 46 are respectively clamped into the clamping cavity 461 of the outer control ring layer 46.

[0029] A clamping rod 47 is rotatably installed on the outside of the ventilation box 1. The clamping rod 47 is L-shaped. Its rotation can squeeze different control ring layers 46, so that the control ring layers 46 squeeze the fabric. The interlocking control ring layers 46 can change the ventilation holes, so that the air permeability of fabrics under different areas can be tested, to prevent fabrics that are too breathable from being difficult to push the metal plug 22.

[0030] When in use, the cloth is clamped between the two layers of adsorbents 41 to keep the cloth stable, and then the cloth is pulled to unfold. During the detection process of different cloths, the degree of unfolding is the same, thereby improving the accuracy of detection;

[0031] Secondly, the limiting ring 2 44 is matched with the limiting ring 1 42 to clamp the fabric, and then the fastener 1 43 and the fastener 2 45 are matched to keep the limiting ring 2 44 stable and fix the fabric, and then different control ring layers 46 are clamped into the clamping cavity 1 421 or the clamping cavity 2 461, and then the clamping rod 47 is rotated to make the control ring layers 46 counteract each other. Different control ring layers 46 can control fabrics of different areas to vent air, ensuring accurate detection, and ventilation from the ventilation end 3 at the upper end of the ventilation box 1, so that the gas enters the ventilation box 1 and goes out from one side of the fabric. However, since the air permeability of different fabrics is different, the gas can push the metal plug 22, and the air permeability of different fabrics can be intuitively detected;

[0032] And the elastic band 23 is clamped by the soft plug 24, so that the length or elasticity of the elastic band 23 changes, so that the movement of the metal plug 22 can be directly observed and always moves in the observation tube 2 to avoid extension, and the operability is strong.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
