Description
Technical Field
The present disclosure relates to a moisture-sensitive deformable fabric, and more particularly, to a moisture-sensitive deformable fabric prepared by a digital jet printing process.
Background
With the improvement of the modern social standard of living, people have higher and higher requirements on functional textiles, and with the continuous appearance of various functional textiles, the development of functional textiles with specific purposes is also gradually improved.
In the case of wearing textiles, they often adhere to the skin of the user as the user's perspiration or ambient humidity increases, resulting in a great reduction in the wearing comfort. Therefore, how to reduce the adhesion between the wearable textile and the body of the user and thereby improve the wearing comfort is an important issue for active research by textile manufacturers.
Disclosure of Invention
The present disclosure provides a moisture-sensitive deformable fabric which can be locally deformed after moisture absorption, facilitates volatilization of sweat, and reduces a sticky feeling of a user's body, thereby providing a good wearing comfort to the user.
According to some embodiments of the present disclosure, a moisture-sensitive deformable fabric includes a base fabric and a moisture-sensitive shrinkable ink. The humidity-sensitive shrinkable ink is sprayed on any surface of the base cloth by using a digital jet printing process, and the humidity-sensitive shrinkable ink forms a hydrophilic area on the surface of the base cloth.
In some embodiments of the present disclosure, the humidity sensitive ink may have a viscosity between 2.5cP and 10.0cP and a surface tension between 22dyne/cm and 32dyne/cm, and the humidity sensitive ink includes 15 to 35 parts by weight of the humidity sensitive resin and 65 to 85 parts by weight of water.

Detailed Description
In the following description, numerous implementation details are set forth in order to provide a thorough understanding of the present disclosure. It should be understood, however, that these implementation details are not to be interpreted as limiting the disclosure. That is, in some embodiments of the disclosure, these implementation details are not necessary, and thus should not be used to limit the disclosure. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings. In addition, the dimensions of the various elements in the drawings are not necessarily to scale, for the convenience of the reader.
Herein, the structure of a polymer or group is sometimes represented by a bond line type (skeletton formula). This notation may omit carbon atoms, hydrogen atoms, and carbon-hydrogen bonds. Of course, the drawing is to be understood as referring to the atoms or atom groups explicitly depicted in the structural formula.
The present disclosure provides a moisture-sensitive deformable fabric having hydrophilic regions sprayed with a moisture-sensitive shrinkable ink. Through the arrangement of the hydrophilic regions, the moisture-sensitive deformable fabric can be locally deformed after absorbing moisture (for example, absorbing sweat), so that a three-dimensional space is generated between the moisture-sensitive deformable fabric and the body of a user, and the contact between the moisture-sensitive deformable fabric and the body of the user is reduced. Therefore, the sweat can be volatilized, the sticky feeling of the body of the user is reduced, and the good wearing comfort of the user is provided.
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 a moisture-sensitive shrinkable ink 120. The moisture-sensitive shrinkable ink 120 is sprayed on any surface 111 of the base fabric 110 by using a digital jet printing process to form a hydrophilic region a1 on the surface 111 of the base fabric 110. In some embodiments, the base fabric 110 may be woven, for example, from elastic fibers, inelastic fibers, or a combination thereof. For example, the base fabric 110 may be a knitted fabric or a woven fabric formed by weaving 92% of polyester fibers and 8% of polyurethane fibers together. In some embodiments, the moisture-sensitive shrinkable ink 120 may be sprayed on the surface 111 of the base fabric 110 facing the external environment, and the hydrophilic regions a1 formed by the moisture-sensitive shrinkable ink 120 may have various patterns, so as to achieve the effect of moisture-sensitive deformation well, which will be described in more detail below.
Specifically, when the user wears the wetness sensation deformable fabric 100 on the body, since the base fabric 110 has a higher hydrophobicity relative to the hydrophilic region a1 formed by the wetness sensation shrinkable ink 120, and the hydrophilic region a1 is formed on the surface 111 of the base fabric 110 facing the external environment, the sweat generated by the user's body is pulled (as shown by the arrow in fig. 1) to be guided from the surface 113 of the base fabric 110 facing the user's body to the surface 111 of the base fabric 110 facing the external environment, thereby facilitating the volatilization of the sweat. On the other hand, sweat directed to the surface 111 of the base fabric 110 may enter the hydrophilic region a1, so that the hydrophilic region a1 is deformed by moisture absorption, thereby locally arching or denting the wetness sensation deformable fabric 100 to create a three-dimensional space between the wetness sensation deformable fabric 100 and the user's body. Accordingly, the contact between the wet deformation fabric 100 and the body of the user can be reduced, the volatilization of sweat can be facilitated, the sticky feeling of the body of the user can be reduced, and the good wearing comfort of the user can be provided.
In some embodiments, the moisture-sensitive shrinkable ink 120 mainly includes 15 to 35 parts by weight of the moisture-sensitive shrinkable resin and 65 to 85 parts by weight of water. The moisture-sensitive shrinkable resin has a plurality of amino groups and hydroxyl groups, and can be firmly arranged on the base fabric 110, thereby imparting excellent moisture-sensitive shrinkability to the moisture-sensitive shrinkable ink 120 and the moisture-sensitive deformable fabric 100 produced therefrom. In some embodiments, the moisture-sensitive shrinkable resin may be prepared by including the following reagents: a polyol, a polyamine, a first crosslinker, and a second crosslinker. In some embodiments, the polyol may be added in an amount of between 0.5 parts by weight and 1.5 parts by weight, the polyamine may be added in an amount of between 40 parts by weight and 50 parts by weight, the first crosslinker may be added in an amount of between 2.2 parts by weight and 2.6 parts by weight, and the second crosslinker may be added in an amount of between 0.4 parts by weight and 0.8 parts by weight.
In some embodiments, the polyol can provide good moisture-like receptivity to the moisture-like shrinkable resin, such that the moisture-like shrinkable ink 120 has good moisture-like receptivity. As such, the moisture-sensitive deformable fabric 100 produced with the moisture-sensitive shrinkage ink 120 can have a high shrinkage per unit area. In some embodiments, the polyol can be, for example, an ether group-containing polyol including polyethylene glycol, polypropylene glycol, or polytetrahydrofuran. In some embodiments, the polyol may have a weight average molecular weight between 200g/mole and 600 g/mole. Specifically, if the weight average molecular weight of the polyol is less than 200g/mole, it may cause the formed moisture-shrinkable resin not to be firmly disposed on the base fabric 110, thereby causing the moisture-deformable fabric 100 to have poor moisture-shrinkable property and washing fastness; on the other hand, if the weight average molecular weight of the polyol is more than 600g/mole, the viscosity of the moisture-sensitive shrinkable ink 120 may be too high to be easily sprayed on the base fabric 110.
In some embodiments, the polyamine can provide good moisture shrinkage feel to the moisture shrinkage feel resin, such that the moisture shrinkage feel ink 120 has good moisture shrinkage feel. As such, the moisture-sensitive deformable fabric 100 produced with the moisture-sensitive shrinkage ink 120 can have a high shrinkage per unit area. In some embodiments, the polyamine may comprise a polyetheramine, a polyamide, or a polyimide. In other embodiments, the polyamine may include an aliphatic amine to preferably provide good moisture shrinkage feel properties to the moisture shrinkage-sensing resin. More specifically, the aliphatic amine may be, for example, hexamethylenediamine, diethylhexamethylenediamine, trimethylhexamethylenediamine, heptamethylenediamine, trimethylethylenediamine, tetraethylethylenediamine, tetramethylethylenediamine, nonylenediamine, laurylamine dipropylenediamine, diethylenetriamine, triethylenetetramine or polyethyleneimine. In some embodiments, the polyamine can have a weight average molecular weight of between 600g/mole and 8000g/mole, and preferably between 800g/mole and 5500 g/mole.
In some embodiments, the first crosslinker can include an isocyanate trimer. Specifically, the first crosslinking agent may include a structural unit as shown in formula (1),
formula (1). In some embodiments, the first crosslinker can comprise an aliphatic isocyanate (e.g., HDI, TMDI, or XDI) trimer, a cycloaliphatic isocyanate (e.g., IPDI, HMDI, or HTDI) trimer, an aromatic isocyanate (e.g., TDI or MDI) trimer, or combinations thereof. The first crosslinker may comprise an isocyanate block. For example, at least both ends of the isocyanate trimer may have an isocyanate block. Specifically, in the first crosslinking agent represented by the formula (1), R1、R2And R3Any two or more of which include isocyanate blocks.
In some embodiments, the second crosslinker may have the same molecular structure as the first crosslinker. In some embodiments, the ratio of the amount of the second crosslinker added to the amount of the first crosslinker added may be, for example, between 1:5 and 1: 3. In some embodiments, the ratio of the total amount of isocyanate blocks in the second crosslinker to the first crosslinker to the total amount of hydroxyl groups in the polyol can be between 1.0 and 2.5.
In some embodiments, the viscosity of the humidity sensitive ink 120 may be between 2.5cP and 10.0cP, so that the ink droplets can be ejected with a suitable size and the humidity sensitive ink 120 can have a suitable fluidity to facilitate the digital inkjet printing process. On the other hand, the surface tension of the humidity sensitive shrinkable ink 120 may be between 22dyne/cm and 32dyne/cm, which is beneficial for the formation of ink droplets at the nozzle and enables the humidity sensitive shrinkable ink 120 to have good permeability. In some embodiments, the particle size (D90) of the dispersoid in the humidity sensitive shrinkable ink 120 can be between 90nm and 360nm, so as to avoid the problem of nozzle clogging during the digital jet printing process and to make the humidity sensitive shrinkable ink 120 have better stability. The particle size (D90) of the dispersoid affects the viscosity of the moisture-sensitive shrinkable ink 120. For example, a smaller dispersoid particle size in the moisture-sensitive shrinkable ink 120 may result in a lower viscosity of the moisture-sensitive shrinkable ink 120. In some embodiments, the pH of the humidity sensitive retractable ink 120 at 25 ℃ may be between 6.0 and 8.5, so as to avoid corroding the nozzle of the inkjet printing apparatus, avoid the ink droplets from depositing on the nozzle to cause blockage, and facilitate the digital inkjet printing process.
In some embodiments, the humidity sensitive shrinkable ink 120 may further include 5 to 10 parts by weight of a humectant, 0.004 to 0.060 parts by weight of a surfactant, and/or 0.002 to 0.020 parts by weight of a defoaming agent. The humectant can ensure that the humidity-sensitive shrinkable ink 120 is not deposited or blocked by condensation in the process of jet printing; the surfactant may maintain the size of the particles (e.g., the moisture-sensitive shrink resin, the humectant, etc.) in the moisture-sensitive shrink ink 120 stable; the anti-foaming agent may ensure that there is no foam in the moisture sensitive shrinkable ink 120. In some embodiments, the humectant may be, for example, glycerol, diethylene glycol, propylene glycol methyl ether, or a combination thereof. In some embodiments, the surfactant can be, for example, a polydimethylsiloxane, a polyether-modified siloxane, a polyether-modified polydimethylsiloxane, or a combination thereof. In some embodiments, the defoamer can be, for example, a polyether modified polydimethylsiloxane, a bubble breaking polysiloxane, a mixture of a bubble breaking polysiloxane dissolved in polyethylene glycol and hydrophobic particles, or a combination thereof.
In some embodiments, the humidity sensitive shrinkable ink 120 may further include an appropriate amount of a dispersant, an appropriate amount of an acid-base modifier, and an appropriate amount of a bacteriostatic agent. The dispersant can ensure that the dispersoids in the humidity-sensitive shrinkable ink 120 are completely dispersed, and prevent the spray head from being blocked by precipitates or aggregates; the pH value of the humidity-sensitive shrinkable ink 120 can be ensured to be between 6.0 and 8.5 by the acid-base regulator, so that the influence of excessive acidity or alkalinity of the humidity-sensitive shrinkable ink 120 on the solubility of each component in the humidity-sensitive shrinkable ink is avoided, and precipitates are easily formed to block a spray head or cause corrosion of the spray head; the bacteriostatic agent can effectively inhibit the growth of bacteria.
In some embodiments, the moisture sensitive shrinkable ink 120 may further include a colorant in an amount suitable to impart a suitable color to the fabric to be jet printed. In some embodiments, the particle size of the colorant (D90) in the moisture-sensitive shrinkable ink 120 may be less than or equal to 250nm, so that the colorant effectively penetrates into the fabric to be jet-printed, thereby improving color fastness. 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 shrinkable ink 120 contains the pigment, the moisture-sensitive shrinkable ink 120 can give local or overall color and moisture-sensitive shrinkable performance to the fabric at one time by a digital jet printing process, thereby effectively solving the problem of color fastness reduction caused by dye migration in the conventional secondary processing.
As described above, the hydrophilic region a1 formed by the moisture-sensitive shrinkable ink 120 may have various patterns to achieve a good moisture-sensitive deformation effect. Referring to fig. 2A, fig. 2B, fig. 2C and fig. 2D, schematic top views of patterns of hydrophilic regions a1 of the wet deformation sensing fabric 100 according to various embodiments of the present disclosure are shown. In the following description, various patterns of hydrophilic region a1 will be described in more detail.
First, please refer to fig. 1 and fig. 2A simultaneously. In some embodiments, hydrophilic region a1 may include a plurality of hollow circular patterns P1. In other words, the humidity sensitive 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, the plurality of hollow circular patterns P1 may be arranged at intervals, thereby reserving space for the moisture-sensitive deformable fabric 100 to deform. In some embodiments, the shortest distance D1 between two adjacent hollow circular patterns P1 may be between 4mm and 12mm, and the distance D2 between the centers O1 of two adjacent hollow circular patterns P1 may be between 10mm and 14 mm. In this way, a sufficient deformation amount of the entire moisture-sensitive deformable fabric 100 can be ensured, and a sufficient space is reserved for the moisture-sensitive deformable fabric 100 to deform. In detail, 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 two hollow circular patterns P1 is less than 10mm, there may be a case where there is not enough space between two hollow circular patterns P1 for the moisture-sensitive deformable fabric 100 to deform, and the moisture-sensitive deformable fabric 100 is easily excessively twisted due to the deformation, which may affect the wearing comfort of the user; 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, the density of the distribution of the hollow circular patterns P1 may be too low, so that the deformation amount of the wet deformation fabric 100 as a whole may be insufficient.
In some embodiments, the diameter H of the hollow circular pattern P1 may be between 5mm and 8mm, and the line width W of the hollow circular pattern P1 may be between 1.5mm 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 whole moisture-sensitive deformable fabric 100 after moisture absorption. In detail, if the diameter H of the hollow circular pattern P1 is less than 5mm and the line width W1 of the hollow circular pattern P1 is more than 3.0mm, the deformation area of the whole wetness sensation deformation fabric 100 may be too large, which affects the wearing comfort of the user; 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, the deformation area of the entire wetness sensation deformable fabric 100 may be too small, so that the deformation amount of the entire wetness sensation deformable fabric 100 may be insufficient. In some embodiments, the plurality of hollow circular patterns P1 may be further arranged in an array to enhance the uniformity of deformation of the moisture sensitive deformable web 100.
Please refer to fig. 1 and fig. 2B simultaneously. In some embodiments, the plurality of hollow circular patterns P1 may be staggered, for example. Specifically, the plurality of hollow circular patterns P1 may be arranged along a first direction X1 and a second direction X2, and an 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 equidistantly along the first direction X1 and the second direction X2. Based on the above configuration, the plurality of hollow circular patterns P1 can be distributed on the surface 111 of the base fabric 110 with 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 two adjacent hollow circular patterns P1, the distance D2 between the centers O1 of two adjacent hollow circular patterns P1, and the diameter H and line width W1 of the hollow circular patterns P1 can all be referred to the embodiment of fig. 2A, and are not described herein again.
Please refer to fig. 1 and fig. 2C simultaneously. In some embodiments, the hydrophilic region a1 may include a plurality of hollow hexagonal patterns P2, and two adjacent hollow hexagonal patterns P2 share a respective one of the 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 centers O2 of two adjacent hollow hexagon patterns P2 may be between 8mm and 16 mm. In this way, a sufficient deformation amount of the entire moisture-sensitive deformable fabric 100 can be ensured, and a sufficient space is reserved for the moisture-sensitive deformable fabric 100 to deform. In some embodiments, the line width W2 of the hollow hexagonal pattern P2 may be between 1.5mm and 3.0 mm. In detail, if the line width W1 of the hollow hexagonal pattern P2 is greater than 3.0mm, the deformation area of the entire wetness sensation deformable fabric 100 may be too large, which may affect the wearing comfort of the user; if the line width W2 of the hollow hexagonal pattern P2 is less than 1.5mm, the deformation area of the entire wetness sensation deformable web 100 may be too small, and the deformation amount of the entire wetness sensation deformable web 100 may be insufficient. In some embodiments, each side of the hollow hexagonal pattern P2 is equal, that is, the hollow hexagonal pattern P2 is a hollow regular hexagon, thereby improving the deformation uniformity of the moisture-sensitive deformable fabric 100.
Finally, please refer to fig. 1 and fig. 2D simultaneously. In some embodiments, the hydrophilic area a1 may include a plurality of bar patterns P3, and a plurality of bar patterns P3 are arranged in parallel and spaced apart. In some embodiments, the line width W3 of the bar pattern P3 may be between 5mm and 20mm, and the shortest distance D4 between two adjacent bar patterns P3 may be between 5mm and 20 mm. Within the above range, the moisture-sensitive deformable web 100 as a whole can have a sufficient deformation amount and a good deformation uniformity. In some embodiments, the line width W3 of the bar pattern P3 may be substantially similar to or the same as the shortest distance D4 between two adjacent bar patterns P3, and the bar patterns P3 may be arranged at equal intervals, so as to provide better deformation uniformity of the wet textured fabric 100.
In the following description, various tests and evaluations are performed on the wet-deformation-sensitive fabric of the embodiments of the present disclosure to further verify the efficacy of the present disclosure.
< experimental example 1: evaluation of Wet shrinkability of Wet-like textured Fabric >
In this experimental example, the moisture-sensitive shrinkable ink was sprayed on the surface of the base cloth by a digital jet printing process to form a moisture-sensitive deformable fabric having a pattern of hydrophilic regions. Then, the moisture-sensitive deformable fabric is soaked in water, and the average concave-convex depth generated after the moisture-sensitive deformable fabric is deformed is measured and calculated. In the moisture-sensitive deformable fabric of each example, the base fabric was a knitted fabric obtained by co-weaving 92% of Polyester (PET) fibers and 8% of polyurethane (OP) fibers, and the base fabric weight was 180 gsm. Additional details of the wet-textured fabrics of the examples and the results of the measurements are shown in table one.
Watch 1
Fig. 3A, fig. 3B, fig. 3C and fig. 3D are schematic side views of the moisture-sensitive deformable fabric having the pattern of the hydrophilic regions of fig. 2A, fig. 2B, fig. 2C and fig. 2D, respectively, after moisture absorption. As can be seen from the table one, the average concave-convex depth of the moisture-sensitive deformable fabric of each example after absorbing moisture can be between 0.37mm and 4.26mm, wherein the pattern of the hydrophilic region of the moisture-sensitive deformable fabric of examples 1 to 16 is a hollow circular pattern, and the average concave-convex depth T1 is between 0.72mm and 1.34mm (as shown in fig. 3A and fig. 3B); the pattern of the hydrophilic regions of the moisture-sensitive deformable fabrics of examples 17 to 22 was a hollow hexagonal pattern and the average concave-convex depth T2 was between 0.37mm and 1.10mm (as shown in fig. 3C); the patterns of the hydrophilic regions of the moisture-sensitive deformable fabrics of examples 23 to 32 were long-striped patterns, and the average concave-convex depth T3 was between 1.18mm and 4.26mm (as shown in fig. 3D), which indicates that the moisture-sensitive deformable fabrics of each example all have a certain degree of deformation after absorbing moisture, and have good moisture-sensitive shrinkability. Overall, when the pattern of the hydrophilic region is a strip pattern, the moisture-sensitive deformable fabric has better moisture-sensitive contractibility.
< experimental example 2: evaluation of Wet-like shrinkability of Wet-like textured fabrics of different Fabric specifications >
In the experimental example, the moisture-sensitive shrinkable ink was sprayed on the surfaces of base fabrics of different specifications by using a digital jet printing process to form a moisture-sensitive deformable fabric having a pattern of hydrophilic regions. Then, the wet-sensing deformation fabric is soaked in water, and the average concave-convex depth generated after the wet-sensing deformation fabric is deformed is measured and calculated. The specification and measurement results of the moisture-sensitive deformable fabric of each example are shown in table two.
As can be seen from the table two, the average concave-convex depth generated after absorbing moisture of the moisture-sensitive deformable fabrics of examples 33 to 41 was between 0.34 and 5.65, indicating that the fabric had a certain degree of deformation. In other words, the moisture-sensitive shrinkable ink disclosed by the invention can be sprayed on base fabrics with different specifications by a digital jet printing process, and the prepared moisture-sensitive deformable fabric has good moisture-sensitive shrinkability.
< experimental example 3: evaluation of tackiness of Wet textured Fabric >
In this experimental example, the tensile viscous force test was performed on the fabric of comparative example 1, which is a knitted fabric obtained by co-weaving 92% of polyester fibers and 8% of polyurethane fibers, and the wet deformation-sensitive fabric of some examples in the table section. The test method is to soak the fabric of the comparative example and the moisture-sensitive deformable fabric of each example in water, place the fabric of the comparative example and the moisture-sensitive deformable fabric of each example on artificial skin, and then stretch the fabric of the comparative example and the moisture-sensitive deformable fabric of each example, wherein the stretching direction is parallel to the rib (rib) direction of the fabric. The test results are shown in table three.
Watch III
As can be seen from table three, the moisture-sensitive deformable fabrics of each example were separated from the artificial skin by a smaller tensile viscous force than the fabrics of the comparative examples. That is, the moisture-sensitive deformable fabric of each embodiment is less likely to stick to the body of the user after being deformed by moisture, and contributes to volatilization of sweat and reduction of the sticky feeling of the body of the user, thereby providing a good wearing comfort to the user.
According to the above embodiments of the present disclosure, the moisture-sensitive deformable fabric of the present disclosure has a hydrophilic region formed by spraying moisture-sensitive shrinkable ink. Through the arrangement of the hydrophilic region, the moisture-sensing deformable fabric can be locally deformed after absorbing moisture, so that a three-dimensional space is generated between the moisture-sensing deformable fabric and the body of a user, and the contact between the moisture-sensing deformable fabric and the body of the user is reduced. Therefore, the sweat can be volatilized, the sticky feeling of the body of the user is reduced, and the good wearing comfort of the user is provided. On the other hand, through the design of the pattern of the hydrophilic area, the moisture-sensitive contractibility of the moisture-sensitive deformable fabric can be further improved.
While the foregoing is directed to embodiments of the present disclosure, other and further embodiments of the disclosure may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
