Detailed ways

Various embodiments of the present disclosure will be disclosed in the accompanying drawings. For clarity of explanation, many practical details will be explained in the following description. However, it should be understood that these practical details should not be used to limit the disclosure. That is to say, in some implementations of the disclosure, these practical details are not necessary and therefore should not be used to limit the disclosure. In addition, for the purpose of simplifying the drawings, some commonly used structures and components will be illustrated in a simple schematic manner in the drawings. In addition, for the convenience of readers, the dimensions of each element in the drawings are not drawn according to actual proportions.

The present disclosure provides a moisture-sensitive deformable fabric having hydrophilic areas sprayed with moisture-sensitive shrinkage ink. Through the configuration of the hydrophilic zone, the moisture-sensing deformation fabric can locally deform after absorbing moisture (for example, absorbing sweat) to create a three-dimensional space between the moisture-sensing deformation fabric and the user's body, thereby reducing the use of the moisture-sensing deformation fabric. body-to-body contact. In this way, it can help evaporate sweat and reduce the stickiness of the user's body, thereby providing the user with good wearing comfort.

FIG. 1 illustrates a schematic side view of a moisture-sensitive deformable fabric 100 according to some embodiments of the present disclosure. The moisture-sensitive deformable fabric 100 includes a base fabric 110 and moisture-sensitive shrinkage ink 120 . The moisture-sensitive shrinkable ink 120 is sprayed on any surface 111 of the base fabric 110 using a digital printing process to form a hydrophilic area A1 on the surface 111 of the base fabric 110 . In some embodiments, the base fabric 110 may be, for example, woven from elastic fibers, non-elastic fibers, or combinations thereof. For example, the base fabric 110 may be a knitted fabric or a woven fabric woven by 92% polyester fiber and 8% polyurethane fiber. In some embodiments, the moisture-sensitive shrinkage ink 120 can be sprayed on the surface 111 of the base fabric 110 facing the external environment, and the hydrophilic area A1 formed by the moisture-sensitive shrinkage ink 120 can have a variety of patterns, so as to achieve a good feel. The effect of wet deformation will be explained in more detail below.

Specifically, when the user wears the moisture-sensitive deformable fabric 100 on the body, the base fabric 110 has higher hydrophobicity relative to the hydrophilic area A1 formed by the moisture-sensitive shrinkage ink 120, and the hydrophilic area A1 is It is formed on the surface 111 of the base fabric 110 facing the external environment. Therefore, the sweat generated by the user's body will receive a pulling force (in the direction of the arrow in Figure 1) and be guided by the surface 113 of the base fabric 110 facing the user's body. The surface 111 of the base fabric 110 faces the external environment, thereby facilitating the evaporation of sweat. On the other hand, the sweat guided to the surface 111 of the base fabric 110 can enter the hydrophilic area A1, causing the hydrophilic area A1 to deform due to moisture absorption, thereby causing the moisture-sensitive deformation fabric 100 to partially arch or dent to facilitate moisture sensing. A three-dimensional space is generated between the deformed fabric 100 and the user's body. This can reduce the contact between the moisture-sensitive deformable fabric 100 and the user's body, help evaporate sweat and reduce the stickiness of the user's body, thereby providing the user with good wearing comfort.

In some embodiments, the weight average molecular weight of the polyol may be between 200 g/mole and 600 g/mole. Specifically, if the weight average molecular weight of the polyol is less than 200 g/mole, the formed moisture-sensitive shrinkage resin may not be firmly disposed on the base fabric 110 , causing the moisture-sensitive deformation fabric 100 to have poor moisture-sensitive shrinkage and Washing fastness; and if the weight average molecular weight of the polyol is greater than 600g/mole, the viscosity of the moisture-sensitive shrinkage ink 120 may be too high, making it difficult to spray on the base fabric 110.

In some embodiments, the polyamine can provide the moisture-sensitive shrinkage resin with good moisture-sensitive shrinkage, so that the moisture-sensitive shrinkage ink 120 has good moisture-sensitive shrinkage.

To facilitate the digital printing process. On the other hand, the surface tension of the moisture-sensitive shrinkable ink 120 can be between 22 dyne/cm and 32 dyne/cm, which is beneficial to the formation of ink droplets at the nozzle and allows the moisture-sensitive shrinkable ink 120 to have good permeability.

The particle size (D90) of the above-mentioned dispersion will affect the viscosity of the moisture-sensitive shrinkage ink 120. For example, a smaller dispersion particle size in the moisture-sensitive shrinkage ink 120 can cause the moisture-sensitive shrinkage ink 120 to have a lower viscosity. In some embodiments, the pH value of the moisture-sensitive shrinkage ink 120 at 25° C. can be between 6.0 and 8.5, thereby avoiding corrosion of the nozzle of the printing device and preventing ink droplets from being deposited on the nozzle to cause clogging.

As mentioned above, the hydrophilic area A1 formed by the moisture-sensitive shrinkage ink 120 can have various patterns to achieve a good effect of moisture-sensitive deformation. Please refer to FIGS. 2A, 2B, 2C and 2D, which illustrate schematic top views of the patterns of the hydrophilic areas A1 of the moisture-sensitive deformable fabric 100 according to different embodiments of the present disclosure. In the following description, various patterns of the hydrophilic region A1 will be described in more detail.

First, please refer to both Figure 1 and Figure 2A. In some embodiments, the hydrophilic area A1 may include a plurality of hollow circular patterns P1. In other words, the moisture-sensitive shrinkage ink 120 is sprayed to form a plurality of hollow circular patterns P1 on the surface 111 of the base fabric 110 . In some embodiments, a plurality of hollow circular patterns P1 may be arranged at intervals, thereby leaving space for the moisture-sensitive deformation fabric 100 to deform. In some embodiments, the shortest distance D1 between two adjacent hollow circular patterns P1 may be between 4 mm and 12 mm, and the distance D2 between the center O1 of each of the two adjacent hollow circular patterns P1 may be between 10 mm. to 14mm. In this way, it is ensured that the moisture-sensitive deformation fabric 100 has a sufficient deformation amount as a whole, and enough space is reserved for the moisture-sensitive deformation fabric 100 to deform. Specifically, if the shortest distance D1 between two adjacent hollow circular patterns P1 is less than 4mm or the distance D2 between the centers O1 of the two hollow circular patterns P1 is less than 10mm, it may result in that there is no space between the two hollow circular patterns P1. There is enough space for the moisture-sensitive deformation fabric 100 to deform, which may easily cause the moisture-sensitive deformation fabric 100 to be excessively distorted due to deformation, affecting the user's wearing comfort; if the shortest distance D1 between two adjacent hollow circular patterns P1 is greater than 12mm or the distance D2 between the centers O1 of the two hollow circular patterns P1 is greater than 14mm, which may cause the distribution density of the hollow circular patterns P1 to be too low, resulting in insufficient deformation of the moisture-sensitive deformation fabric 100 as a whole.

In some embodiments, the diameter H of the hollow circular pattern P1 may range from 5 mm to 8 mm, and the line width W of the hollow circular pattern P1 may range from 1.5 mm to 3.0 mm. The diameter H of the hollow circular pattern P1 and the line width W1 of the hollow circular pattern P1 can affect the area of the hollow circular pattern P1, thereby affecting the overall deformation amount of the moisture-sensitive deformation fabric 100 after absorbing moisture. Specifically, if the diameter H of the hollow circular pattern P1 is less than 5 mm and the line width W1 of the hollow circular pattern P1 is greater than 3.0 mm, the overall deformation area of the moisture-sensitive deformation fabric 100 may be too large, affecting the user's wearing comfort. ; If the diameter H of the hollow circular pattern P1 is greater than 8mm and the line width W1 of the hollow circular pattern P1 is less than 1.5mm, it may cause the overall deformation area of the moisture-sensitive deformation fabric 100 to be too small, causing the overall deformation of the moisture-sensitive deformation fabric 100 Insufficient quantity. In some embodiments, the plurality of hollow circular patterns P1 can be further arranged in an array, thereby improving the deformation uniformity of the moisture-sensitive deformation fabric 100 .

Next, please refer to Figure 1 and Figure 2B at the same time. In some embodiments, the plurality of hollow circular patterns P1 may be arranged in a staggered manner, for example. Specifically, the plurality of hollow circular patterns P1 may be arranged along the first direction X1 and the second direction X2, and the angle θ between the first direction X1 and the second direction X2 is between 40 degrees and 50 degrees. In some embodiments, the plurality of hollow circular patterns P1 may be equidistantly arranged along the first direction X1 and the second direction X2. Based on the above configuration, a plurality of hollow circular patterns P1 can be distributed on the surface 111 of the base fabric 110 at an appropriate density to ensure that the moisture-sensitive deformation fabric 100 has a certain degree of deformation after absorbing moisture. It should be understood that the shortest distance D1 between two adjacent hollow circular patterns P1, the distance D2 between the respective center O1 of two adjacent hollow circular patterns P1, and the diameter H and line width W1 of the hollow circular patterns P1 are all Reference may be made to the implementation of FIG. 2A , which will not be described again here.

Then, please refer to Figure 1 and Figure 2C at the same time. In some embodiments, the hydrophilic area A1 may include a plurality of hollow hexagonal patterns P2, and two adjacent hollow hexagonal patterns P2 share one of their respective sides. In other words, the plurality of hollow hexagonal patterns P2 form a honeycomb pattern on the surface 111 of the base fabric 110 . In some embodiments, the distance D3 between the respective centers O2 of two adjacent hollow hexagonal patterns P2 may range from 8 mm to 16 mm. In this way, it is ensured that the moisture-sensitive deformation fabric 100 has a sufficient deformation amount as a whole, and enough space is reserved for the moisture-sensitive deformation fabric 100 to deform. In some embodiments, the line width W2 of the hollow hexagonal pattern P2 may range from 1.5 mm to 3.0 mm. Specifically, if the line width W1 of the hollow hexagonal pattern P2 is greater than 3.0mm, the overall deformation area of the moisture-sensitive deformable fabric 100 may be too large, affecting the user's wearing comfort; if the line width W1 of the hollow hexagonal pattern P2 If the width W2 is less than 1.5 mm, the overall deformation area of the moisture-sensitive deformation fabric 100 may be too small, causing the overall deformation amount of the moisture-sensitive deformation fabric 100 to be insufficient. In some embodiments, each side length of the hollow hexagon pattern P2 is equal, that is, the hollow hexagon pattern P2 is a hollow regular hexagon, thereby improving the deformation uniformity of the moisture-sensitive deformation fabric 100 .

Finally, please refer to both Figure 1 and Figure 2D. In some embodiments, the hydrophilic region A1 may include a plurality of elongated patterns P3, and the plurality of elongated patterns P3 are arranged in parallel and at intervals. In some embodiments, the line width W3 of the strip pattern P3 may range from 5 mm to 20 mm, and the shortest distance D4 between two adjacent strip patterns P3 may range from 5 mm to 20 mm. Within the above range, the entire moisture-sensitive deformation fabric 100 can have sufficient deformation amount and good deformation uniformity. In some embodiments, the line width W3 of the strip pattern P3 may be substantially similar or the same as the shortest distance D4 between two adjacent strip patterns P3, and the strip patterns P3 may be arranged equidistantly, so that The moisture-sensitive deformation fabric 100 is provided with better deformation uniformity.
