Description

Technical Field

[0001] The present invention relates to the technical field of flocked fabrics, in particular to the technical field of a self-temperature sensing and management flocked fabric and its preparation method.

Background Art

[0002] Flocking is a process that utilizes the physical property of like charges repelling and opposite charges attracting. Negative charges are applied to the fluff, and the object to be flocked coated with an adhesive is placed at zero potential or grounded. Under the attraction of the object with opposite potential, the fluff accelerates vertically and is pasted onto the surface of the object to be flocked. A flocked fabric is a fabric obtained by flocking a layer of fluff on the front surface of various base fabrics, which has the characteristics of strong three-dimensional sense, soft hand feeling, wear resistance, and flatness without gaps, and can be applied in the fields of clothing, furniture, handicrafts, and luggage. However, due to the dense layer of fluff on the surface of the existing flocked fabrics, although they have good warmth retention, their air permeability and sweat wicking performance are poor, making it difficult to be applied in the field of sportswear.

[0003] Conventional sportswear fabrics on the market mostly obtain the function of quick moisture absorption and drying through coating processes or adding additives. The principle is to add hydrophilic groups to the fibers to enhance the moisture absorption ability of the fabric. After the fibers adsorb water vapor, it can be quickly transferred between the fibers, increasing the diffusion speed per unit area, and then quickly evaporating the water vapor into the air. However, after 50 washes, the hydrophilic groups fall off, and the moisture absorption and sweat wicking function effect will be reduced to about 20% of the original, resulting in the inability to meet the sweat and heat dissipation effects during exercise. In addition, when static, it cannot play the role of moderately preserving the heat of the skin.

Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the prior art, and propose a self-temperature sensing and management flocked fabric and its preparation method. The prepared fabric has high warmth retention characteristics while also achieving high air permeability, and can effectively improve the body feeling when applied in the field of sportswear.

[0005] To achieve the above purpose, the present invention is realized through the following technical solutions:

[0006] A self-temperature sensing and management flocked fabric, comprising a base fabric and fluff, wherein the fluff is flocked on one side of the base fabric in a non-compact manner to form a number of cavities.

[0007] Preferably, the fluff is flocked on one side of the base fabric in a honeycomb arrangement.

[0008] Preferably, several rows of fluff arranged in a honeycomb pattern are flocked on one side of the base fabric at intervals, and several rows are spaced between adjacent two rows of fluff.

[0009] Preferably, several columns of the villi arranged in a honeycomb pattern are spacedly planted on one side of the base fabric, and several columns are spaced between adjacent two columns of the villi.

[0010] Preferably, the villi are special-shaped short villi. The cross-sectional shape of the villi is triangular, trilateral, polygonal, bilobed, trilobed, multilobed, fan-shaped, hollow or flat. The length of the villi is 0.5 - 2.5 mm, preferably 1 mm.

[0011] Preferably, the base fabric is a mesh fabric with several through holes.

[0012] Preferably, the base fabric is a knitted fabric prepared by a looping process.

[0013] A preparation method of a flocked fabric with self-temperature sensing management includes the following steps:

[0014] a) Wax sealing: Coating molten wax liquid on a partial area of one side of the base fabric;

[0015] b) Flocking: After the wax liquid solidifies and forms several wax dots, using an electrostatic flocking device to flock the villi non-compactly on one side of the base fabric and form several cavities, and the positions of the wax dots coincide with the positions of the cavities;

[0016] c) Wax removal: After standing at room temperature for 6 - 24 h, boiling the wax dots off with hot water;

[0017] d) Post-treatment: Successively drying and shearing to obtain the finished product.

[0018] Preferably, the wax liquid in the step a) is anti-dyeing wax.

[0019] Preferably, in the step b), the voltage of the electrostatic flocking is 60 - 80 KV, the time is 5 - 10 s, and the plate distance is 8 - 12 cm.

[0020] Advantages of the present invention: By using a mesh fabric with a number of through-holes as the base fabric, and then non-compactly planting a layer of fluff on one side of the base fabric to form a number of cavities, under dynamic conditions, air circulates freely, which can reduce the heat accumulated in the fabric, and the contact points between the fabric and the skin can absorb sweat and diffuse and evaporate it, instantly repelling the stuffy feeling. Under static conditions, the outer base fabric resists the wind, and the inner fluff automatically forms a constant-temperature protection layer suitable for the human body on the skin surface, which is skin-friendly, soft and warm; by using a knitted fabric prepared by a looping process as the base fabric of the outer layer in the double-sided structure, it can effectively increase the gaps between the yarns, neither being loose nor affecting air circulation and water vapor evaporation; by distributing the special-shaped short fluff in a honeycomb structure on one side of the base fabric, the heat and water vapor generated by the human body during dynamic movement automatically concentrate in the honeycomb, and using the siphon effect generated by the pressure difference on both sides of the base fabric, the heat dissipation and sweating speed are accelerated. Under static conditions, the special-shaped short fluff arranged in a honeycomb shape can also play a role in heat preservation and heat storage, enabling the body to transition slowly and reducing discomfort caused by its own or environmental changes; by pre-coating the area corresponding to the cavities on the base fabric with wax liquid to form wax dots, it can block the cavities during flocking to prevent fluff from entering and blocking the cavities, thus not affecting the air permeability of the fabric.

[0021] The features and advantages of the present invention will be described in detail through examples in conjunction with the accompanying drawings.

Detailed Embodiments

[0027] Embodiment 1:

[0028] Refer to Figures 1 to 3 , a flocked fabric with self-temperature sensing management, including a base fabric 1 and fluff 2, and the fluff 2 is non-compactly planted on one side of the base fabric 1 to form a number of cavities 21.

[0029] The fluff 2 is planted on one side of the base fabric 1 in a honeycomb arrangement.

[0030] The villi 2 are special-shaped short villi. The cross-sectional shape of the villi is triangular, trilateral, polygonal, bilobed, trilobed, multilobed, fan-shaped, hollow or flat. The length of the villi 2 is 1 mm.

[0031] The base cloth 1 is a mesh fabric with a number of through holes 11.

[0032] The base cloth 1 is a knitted fabric prepared by the loop process.

[0033] A method for preparing a flocked fabric with self-temperature sensing management, characterized by comprising the following steps:

[0034] a) Wax sealing:

[0035] First, the base cloth 1 is pre-shaped to make the fabric flat, and then molten wax liquid, which is anti-dyeing wax, is coated on a partial area of one side of the base cloth 1.

[0036] b) Flocking:

[0037] After the wax liquid solidifies and forms a number of wax dots, the electrostatic flocking equipment is used to flock the villi 2 non-compactly on one side of the base cloth 1 to form a number of cavities 21, and the positions of the wax dots coincide with the positions of the cavities 21. The voltage of the electrostatic flocking is 60 - 80 KV, the time is 5 - 10 s, and the distance between the electrodes is 8 - 12 cm;

[0038] Among them, the electrostatic flocking equipment flocks the villi 2 non-compactly on one side of the base cloth 1 specifically as follows: First, an adhesive is coated on the fabric by a flower roller to form an adhesive layer with the flower pattern of the flower roller on the surface of the fabric, and then the negatively charged villi are sprayed out through the flocking nozzle. Since the potential of the adhesive on the base cloth 1 is 0 level, the principle of attraction between different electrodes can be used to make the villi quickly pierce into the adhesive, thus forming a flocking pattern. Also, due to the principle of repulsion between the same electrodes, the villi are perpendicular to each other.

[0039] c) Wax removal:

[0040] After standing at room temperature for 6 - 24 h, the wax dots are removed by boiling with hot water.

[0041] d) Post-treatment:

[0042] Drying and shearing are carried out successively to obtain the finished product.

[0043] Example 2:

[0044] Refer to Figure 4 , several rows of the villi 2 arranged in a honeycomb pattern are flocked on one side of the base cloth 1 at intervals, and there are 2 rows between adjacent two rows of the villi 2. Others are the same as in Example 1.

[0045] When in motion, the body's heat dissipation and sweat secretion increase rapidly. On conventional moisture-absorbing and sweat-wicking fabrics, the moisture-absorbing areas are evenly distributed, and water vapor needs to pass to the outside world sequentially. The fabric prepared by the present invention uses a mesh fabric with a number of through holes as the base fabric, and then a layer of fluff is non-tightly planted on one side of the base fabric, thus forming a number of cavities. Among them, the side in contact with the skin on the inner layer has a cavity structure, which can serve as a buffer zone to temporarily store a large amount of heat and moisture. At the same time, the base fabric structure can quickly diffuse moisture and heat, and the air circulation speed also relatively increases during motion. The three work together synergistically to jointly avoid the phenomenon that the heat and sweat in the inner layer increase sharply and cannot circulate. Moreover, due to the heat difference between the fluff position and the cavity position in the inner layer, there can be a slight temperature difference on the skin surface, thus giving the skin a cool feeling, and the perceived temperature can have a difference of 1 - 1.5 °C. The moisture-absorbing and sweat-wicking effect is 2 - 3 times that of conventional fabrics and can permanently maintain this effect.

[0046] When in a relatively static state, since the heat and water vapor to be discharged inside are relatively reduced, the body needs to retain a part of the heat to slowly adapt. From the perspective of physical health, the base fabric of the fabric prepared by the present invention adopts a loop knitting process to make the fabric elastic, thereby increasing the tightness between the yarns, being able to lock the heat in time and then release it slowly. Moreover, the special-shaped short fluff arranged in a honeycomb shape on the inner layer of the fabric itself can also play a role in warming and heat storage, so it is more conducive to the slow transition of the body's temperature perception, reducing discomfort caused by its own or environmental changes, and thus preventing some situations of getting cold after strenuous exercise.

[0047] The fabric prepared by the present invention is a self-temperature-sensing management fabric developed and designed for specific scenarios, such as in scenarios like urban night running, home exercise, mountain climbing, and playing, etc., so there is no need to specifically change clothes, bringing the convenience of multi-functional use.

[0048] The above embodiments are illustrative of the present invention, not restrictive of the present invention. Any scheme obtained by simply transforming the present invention belongs to the protection scope of the present invention.
