Description

Wet textured fabric

The present disclosure relates to a moisture-sensitive textured fabric, and more particularly, to a moisture-sensitive textured fabric prepared by a digital jet printing process.

With the improvement of living standards in today's society, people's demand for functional textiles is getting higher and higher, and with the continuous advent of various functional textiles, the development of functional textiles with specific purposes is also becoming more and more perfect.

For wearable textiles, they often adhere to the user's skin as the user's sweat or ambient humidity increases, resulting in greatly reduced wearing comfort. Therefore, how to reduce the adhesion between the wearable textile and the user's body and thereby improve the wearing comfort is an important topic of active research by textile manufacturers.

The present disclosure provides a moisture-sensitive deformable fabric, which can be deformed locally after absorbing moisture, which helps to volatilize sweat and reduce the stickiness of the user's body, thereby providing the user with a good wearing comfort.

According to some embodiments of the present disclosure, a moisture-sensitive textured fabric includes a base fabric and a moisture-sensitive shrinkage ink. The moisture-sensitive shrinkage ink is sprayed on any surface of the base cloth by a digital jet printing process, and the moisture-sensitive shrinkage ink forms a hydrophilic area on the surface of the base cloth.

In some embodiments of the present disclosure, the moisture shrinkage ink may have a viscosity between 2.5 cP and 10.0 cP and a surface tension between 22 dyne/cm and 32 dyne/cm, and the moisture shrinkage ink includes 15 to 35 parts by weight of moisture-sensitive resin and 65 to 85 parts by weight of water.

In some embodiments of the present disclosure, the moisture shrinkable resin may be prepared by including the following reagents: polyol, polyamine, a first cross-linking agent, and a second cross-linking agent. The first crosslinking agent and the second crosslinking agent each include an isocyanate block.

In some embodiments of the present disclosure, the hydrophilic region may include a plurality of hollow circular patterns, and the hollow circular patterns are arranged at intervals.

In some embodiments of the present disclosure, the hollow circular patterns may be arranged in an array.

In some embodiments of the present disclosure, the hollow circular patterns may be arranged along the first direction and the second direction, and the included angle between the first direction and the second direction is between 40 degrees and 50 degrees.

In some embodiments of the present disclosure, the hydrophilic region may include a plurality of hollow hexagonal patterns, and two adjacent hollow hexagonal patterns share one side of each.

In some embodiments of the present disclosure, each side of the hollow hexagonal pattern may be equal in length.

In some embodiments of the present disclosure, the hydrophilic region may include a plurality of elongated patterns, and the elongated patterns are arranged in parallel.

In some embodiments of the present disclosure, the elongated patterns may be arranged at equal distances.

According to the above embodiments of the present disclosure, the moisture-sensitive deformation fabric of the present disclosure has a hydrophilic region sprayed with moisture-sensitive shrinkage ink. Through the configuration of the hydrophilic area, the moisture-sensitive textured fabric can be deformed locally after absorbing moisture, so as to create a three-dimensional space between the moisture-sensitive textured fabric and the user's body, thereby reducing the contact between the moisture-sensitive textured fabric and the user's body. In this way, the volatilization of sweat can be facilitated and the stickiness of the user's body can be reduced, thereby providing the user with a good wearing comfort.

Several embodiments of the present disclosure will be disclosed in the following drawings, and for the sake of clarity, many practical details will be described together in the following description. It should be understood, however, that these practical details should not be used to limit the present disclosure. That is to say, in some embodiments of the present disclosure, these practical details are unnecessary, and therefore should not be used to limit the present disclosure. In addition, for the purpose of simplifying the drawings, some well-known structures and elements will be shown in a simple and schematic manner in the drawings. In addition, for the convenience of the reader, the size of each element in the drawings is not drawn according to the actual scale.

Herein, the structure of a polymer or group is sometimes represented by a skeleton formula. This representation can omit carbon atoms, hydrogen atoms, and carbon-hydrogen bonds. Of course, where atoms or atomic groups are clearly drawn in the structural formula, the drawing shall prevail.

The present disclosure provides a moisture-sensitive textured fabric having a hydrophilic region sprayed with moisture-sensitive shrinkage ink. Through the configuration of the hydrophilic area, the moisture-sensitive deformable fabric can be locally deformed after absorbing moisture (for example, absorbing sweat), so as to create a three-dimensional space between the moisture-sensitive deformable fabric and the user's body, thereby reducing the moisture-sensitive deformable fabric and the user's body. physical contact. In this way, the volatilization of sweat can be facilitated and the stickiness of the user's body can be reduced, thereby providing the user with a good wearing comfort.

FIG. 1 is a schematic side view of a moisture deformable fabric 100 according to some embodiments of the present disclosure. The moisture-sensitive deformation fabric 100 includes a base fabric 110 and a moisture-sensitive shrinkage ink 120 . The moisture-sensitive shrinkage ink 120 is sprayed on any surface 111 of the base fabric 110 by a digital printing process, so as to form a hydrophilic area A1 on the surface 111 of the base fabric 110 . In some embodiments, the base fabric 110 may be woven from elastic fibers, inelastic fibers, or a combination thereof, for example. For example, the base fabric 110 can be, for example, a knitted fabric or a woven fabric that is co-woven with 92% polyester fiber and 8% polyurethane fiber. In some embodiments, the moisture-sensitive shrinkable 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 shrinkable ink 120 can have various patterns, so as to well achieve moisture-sensitive deformation effect, which will be described in more detail below.

Specifically, when the user wears the moisture-sensitive deformable fabric 100 on the body, since the base fabric 110 has higher hydrophobicity relative to the hydrophilic area A1 formed by the moisture-sensitive shrinkable ink 120, and the hydrophilic area A1 is formed again Since the surface 111 of the base fabric 110 faces the external environment, the sweat generated by the user's body will be subjected to a pulling force (such as the arrow direction in FIG. 1 ) to be guided from the surface 113 of the base fabric 110 facing the user's body to The base cloth 110 faces the surface 111 of the external environment, thereby facilitating the volatilization of sweat. On the other hand, the sweat guided to the surface 111 of the base fabric 110 can enter the hydrophilic area A1, so that the hydrophilic area A1 is deformed due to moisture absorption, so that the moisture-sensitive deformable fabric 100 is partially arched or dented for moisture-sensitive deformation A three-dimensional space is created between the fabric 100 and the user's body. Thereby, the contact between the moisture-sensitive deformable fabric 100 and the user's body can be reduced, which is helpful for the volatilization of sweat and reduces the stickiness of the user's body, thereby providing the user with a good wearing comfort.

In some embodiments, the moisture shrinkage ink 120 mainly includes 15 to 35 parts by weight of the moisture shrinkable resin and 65 to 85 parts by weight of water.

In some embodiments, the polyol may have a weight average molecular weight 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-shrinkable resin may not be firmly arranged on the base fabric 110, so that the moisture-deformable fabric 100 has poor moisture-shrinkability and Washing fastness; and if the weight-average molecular weight of the polyol is greater than 600 g/mole, the viscosity of the moisture shrinkage ink 120 may be too high, so that it is difficult to be sprayed on the base fabric 110 .

In some embodiments, the polyamine can provide the moisture-sensitive resin with good moisture-shrinkability, so that the moisture-shrinkable ink 120 has good moisture-shrinkability. In this way, the moisture sensitive textured fabric 100 prepared with the moisture sensitive shrinkage ink 120 can have a high unit area shrinkage rate. In some embodiments, the polyamine may include polyetheramine, polyamide, or polyimide. In other embodiments, the polyamines may include aliphatic amines to preferably provide good moisture shrinkage properties of the moisture shrinkable resin. More specifically, the aliphatic amine may be, for example, hexamethylenediamine, diethylhexamethylenediamine, trimethylhexamethylenediamine, heptanediamine, trimethylethylenediamine, tetraethylethylenediamine, tetramethylethylenediamine Ethylenediamine, nonanediamine, laurylaminedipropylenediamine, diethylenetriamine, triethylenetetramine or polyethyleneimine. In some embodiments, the weight average molecular weight of the polyamine may be between 600 g/mole and 8000 g/mole, and preferably between 800 g/mole and 5500 g/mole.

In some embodiments, the viscosity of the moisture-shrinkable ink 120 can be between 2.5 cP and 10.0 cP, so that the ink droplets printed can have a suitable size and the moisture-shrinkable ink 120 can have a suitable fluidity In order to facilitate the digital printing process. On the other hand, the surface tension of the moisture 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 enables the moisture shrinkage ink 120 to have good permeability. In some embodiments, the particle size (D90) of the dispersoid in the moisture-sensitive shrinkage ink 120 may be between 90 nm and 360 nm, so as to avoid the problem of nozzle clogging during the digital printing process, and to make the The wet shrinkage ink 120 has better stability. The particle size (D90) of the above-mentioned dispersoid will affect the viscosity of the moisture-shrinking ink 120 . For example, the smaller particle size of the dispersoid in the moisture-shrinkable ink 120 can make the moisture-shrinkable ink 120 have a lower viscosity. In some embodiments, the pH value of the moisture-sensitive shrinkable ink 120 at 25° C. can be between 6.0 and 8.5, so as to avoid corrosion of the print head of the printing device and prevent ink droplets from depositing at the print head to cause clogging, which is beneficial. in the digital printing process.

In some embodiments, the colorant may be, for example, a pigment or dye, and the dye may be, for example, a disperse dye, a high temperature type disperse dye, a reactive dye, or an acid dye. When the moisture-sensitive ink 120 contains a colorant, the moisture-sensitive ink 120 can impart partial or comprehensive color and moisture-shrinking properties to the fabric at one time through the digital jet printing process, effectively solving the problems caused by dyes in traditional secondary processing. The problem of color fastness decline caused by migration.

As mentioned above, the hydrophilic area A1 formed by the moisture-sensitive shrinkage ink 120 can have various patterns, so as to achieve the effect of moisture-sensitive deformation. Please refer to FIGS. 2A , 2B, 2C, and 2D, which are schematic top views of patterns of the hydrophilic area A1 of the moisture-sensitive textured fabric 100 according to various 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 region A1 may include a plurality of hollow circular patterns P1. In other words, the moisture shrinkable 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, so as to reserve a space for the wet deformation sensitive fabric 100 to be deformed. 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 respective centers O1 of the two adjacent hollow circular patterns P1 may be 10 mm to 14mm. In this way, it can be ensured that the entire wet deformation sensitive fabric 100 has a sufficient deformation amount, and sufficient space is reserved for the wet deformation sensitive fabric 100 to be deformed. In detail, if the shortest distance D1 between the two adjacent hollow circular patterns P1 is less than 4 mm or the distance D2 between the respective centers O1 of the two hollow circular patterns P1 is less than 10 mm, there may be no space between the two hollow circular patterns P1. There is enough space for deformation of the moisture-sensitive deformable fabric 100, which is easy to cause the moisture-sensitive deformable fabric 100 to be excessively twisted due to the deformation, which affects the wearing comfort of the user; if the shortest distance D1 between the adjacent two hollow circular patterns P1 is greater than 12 mm or the distance D2 between the centers O1 of the two hollow circular patterns P1 is greater than 14 mm, which may cause the distribution density of the hollow circular patterns P1 to be too low, resulting in insufficient deformation of the wet deformable fabric 100 as a whole.

In some embodiments, the diameter H of the hollow circular pattern P1 may be between 5 mm and 8 mm, and the line width W of the hollow circular pattern P1 may be between 1.5 mm and 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 to affect the deformation amount of the moisture-sensitive deformable fabric 100 as a whole after moisture absorption. In detail, 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 entire deformation area of the moisture-sensitive deformable fabric 100 may be too large, affecting the wearing comfort of the user. ; If the diameter H of the hollow circular pattern P1 is greater than 8 mm and the line width W1 of the hollow circular pattern P1 is less than 1.5 mm, the deformation area of the entire moisture-sensitive deformation fabric 100 may be too small, causing the overall deformation of the moisture-sensitive deformation fabric 100. Insufficient amount. In some embodiments, the plurality of hollow circular patterns P1 can be further arranged in an array, so as to improve the deformation uniformity of the wet deformation-sensitive 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 can be arranged along the first direction X1 and the second direction X2, and the included 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 arranged at equal distances 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 a suitable density to ensure that the moisture-sensitive deformable fabric 100 has a certain degree of deformation after absorbing moisture. It should be understood that the shortest distance D1 between the two adjacent hollow circular patterns P1, the distance D2 between the respective circle centers O1 of the two adjacent hollow circular patterns P1, and the diameter H and line width W1 of the hollow circular pattern P1 are all Reference may be made to the embodiment in FIG. 2A , which will not be repeated here.

Afterwards, please refer to both Figure 1 and Figure 2C. In some embodiments, the hydrophilic region 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-like 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 be between 8 mm and 16 mm. In this way, it can be ensured that the entire wet deformation sensitive fabric 100 has a sufficient deformation amount, and sufficient space is reserved for the wet deformation sensitive fabric 100 to be deformed. In some embodiments, the line width W2 of the hollow hexagonal pattern P2 may be between 1.5 mm and 3.0 mm. In detail, if the line width W1 of the hollow hexagonal pattern P2 is greater than 3.0 mm, the overall deformation area of the moisture-sensitive deformation fabric 100 may be too large, which affects the wearing comfort of the user; if the lines of the hollow hexagonal pattern P2 If the width W2 is less than 1.5 mm, the deformation area of the entire moisture-deformable fabric 100 may be too small, resulting in insufficient deformation of the entire moisture-deformable fabric 100 . In some embodiments, the length of each side of the hollow hexagonal pattern P2 is equal, that is, the hollow hexagonal pattern P2 is a hollow regular hexagon, so as to improve the deformation uniformity of the wet deformation sensitive 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 spaced apart. In some embodiments, the line width W3 of the elongated pattern P3 may be between 5 mm and 20 mm, and the shortest distance D4 between two adjacent elongated patterns P3 may be between 5 mm and 20 mm. Within the above range, the entire moisture deformation sensitive fabric 100 can have a sufficient deformation amount and a good deformation uniformity. In some embodiments, the line width W3 of the long strip patterns P3 can be substantially similar to or the same as the shortest distance D4 between two adjacent long strip patterns P3, and the long strip patterns P3 can be arranged at equal distances, so that Provides better deformation uniformity of the wet deformation fabric 100 .

On the whole, when the pattern of the hydrophilic region is a long strip pattern, the moisture-sensitive deformation fabric has better moisture-sensitive shrinkage. >Experimental example 2: Evaluation of moisture-sensitive shrinkage of wet-textured fabrics with different fabric specifications>

In this experimental example, the moisture-sensitive shrinkage ink was sprayed on the surface of base fabrics of different specifications by a digital spray printing process to form a moisture-sensitive textured fabric with a pattern of hydrophilic regions.

It can be seen from Table 3 that, compared with the fabrics of the comparative example, the moisture-sensitive and deformable fabrics of each example can be separated from the artificial skin through a smaller tensile viscous force. That is to say, the moisture-sensitive deformable fabric of each embodiment is not easy to stick to the user's body after the moisture-sensitive deformation, which is helpful for the volatilization of sweat and reduces the stickiness of the user's body, thereby providing the user with a good wearing comfort. .

According to the above embodiments of the present disclosure, the moisture-sensitive deformation fabric of the present disclosure has a hydrophilic region sprayed with moisture-sensitive shrinkage ink. Through the configuration of the hydrophilic area, the moisture-sensitive textured fabric can be deformed locally after absorbing moisture, so as to create a three-dimensional space between the moisture-sensitive textured fabric and the user's body, thereby reducing the contact between the moisture-sensitive textured fabric and the user's body. In this way, the volatilization of sweat can be facilitated and the stickiness of the user's body can be reduced, thereby providing the user with a good wearing comfort. On the other hand, through the design of the pattern of the hydrophilic area, the moisture shrinkage of the moisture sensitive textured fabric can be further improved.

Although the present disclosure has been disclosed as above in embodiments, it is not intended to limit the present disclosure. Anyone skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the present disclosure protects The scope shall be determined by the scope of the appended patent application.
