Description

Technical Field

[0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a fabric which utilizes visual interference to reduce the visibility of sweat marks. Background Art

[0002] When people exercise, they prefer to wear more breathable T-shirts. However, people will produce a lot of sweat when running, and existing T-shirts cannot evaporate the sweat quickly. Therefore, sweat will accumulate, and the accumulated sweat will cause the clothes to become wet and sticky, and then stick to the wearer's skin, causing discomfort to the wearer. At the same time, when the human body sweats a lot, the sweat will often penetrate the outside of the clothes, leaving many circles of sweat marks on the surface of the clothes, which not only affects the appearance of the clothes, but also easily makes the clothes yellow. The existing sweat treatment solutions for fabrics corresponding to the human body sweating a lot are mainly as follows:

[0003] Chinese patent document CN208484320U discloses "a moisture-absorbing and perspiration-wicking printed knitted fabric", which includes a common fabric layer, a reinforcement layer adhered to the top of the common fabric layer, air holes are arranged inside the fabric layer and the reinforcement layer, and the air holes are arranged in several groups, a wear-resistant layer is arranged at one end of the air hole, a water-absorbing fabric layer is laid at the other end of the air hole, and anti-static fabric is inlaid inside the wear-resistant layer. The utility model can quickly absorb and discharge human sweat by combining the water-absorbing fabric layer with the common fabric layer, and at the same time increase the air permeability, making it more comfortable to use. The bamboo charcoal fabric layer and the silver ion fabric layer can eliminate the odor and oil smoke produced by the human body, and at the same time have the function of sterilization and disinfection. By combining the wear-resistant layer and the reinforcement layer, the knitted fabric can be made more wear-resistant and durable. The wear-resistant layer is sprayed with a wear-resistant coating and has a good wear-resistant effect. The reinforcement layer is made of nylon thread and has better tensile resistance.

[0004] Chinese patent document CN107354715A discloses "a long-lasting antibacterial, anti-perspiration and non-ironing finishing liquid and finishing process for cotton fabrics". The finishing liquid is compounded with chitosan and Chinese herbal medicine extracts, nano zinc oxide, nano silver powder and other additives. Chitosan is naturally non-toxic and degradable, has good biocompatibility, excellent antibacterial properties, and contains a large number of active groups on the surface, which is beneficial to the shrinkage and wrinkle resistance effect; Arabic gum forms a film to wrap honeysuckle extract, houttuynia extract, pomegranate peel extract and nano zinc oxide, nano silver powder antibacterial agents to achieve sustained release and long-lasting antibacterial effects, compound chitosan, giving cotton fabrics good wrinkle resistance, non-ironing properties, and antibacterial properties, and improving the feel, strength and washability of cotton fabrics; the finished fabrics have good antibacterial, tolerance, wrinkle resistance and non-ironing properties, sweat marks can be instantly absorbed and volatilized, good air permeability, and comfortable to wear; oscillating drying avoids the pressure roller equipment affecting the air permeability of the fabric.

[0005] Chinese patent document CN103161045B discloses "a method for anti-sweat finishing of moisture-absorbing and perspiration-releasing knitted fabrics", which is characterized by: including the following process flow: knitted fabric softening processing → sizing → knitted fabric front anti-sweat processing → anti-sweat inspection → baking. By subjecting the knitted fabric to a moisture-absorbing and perspiration-releasing softening treatment, sweat can be instantly absorbed and volatilized; then, a thin film coating with many breathable micropores is formed on the surface of the knitted fabric by means of paint printing, and each micropore is smaller than sweat and larger than the sweat molecules of the human body. By emitting sweat in the form of gas, sweat marks are not left on the surface of the clothing, thus achieving an anti-sweat effect. The back of the knitted fabric that has been processed with anti-sweat absorbs moisture and dries quickly, and the surface is sweat-resistant. At the same time, it has good air permeability and is comfortable to wear, which is conducive to promotion and application.

[0006] Chinese patent document CN1414081A "A washing powder capable of removing yellow sweat stains discharged from human body on light-colored clothes" has the following active ingredients: sodium dodecyl sulfate 10-20%, fatty alcohol polyoxyethylene ether (n=9) 10-15%, 4A zeolite 10-20%, NaHSO4 10-30%, NaNO2 10-20%, all of which are in mass percentage. The washing powder has the decontamination ability of ordinary washing powder and can remove yellow sweat stains on light-colored clothes. It has obvious effect, mild reaction, no irritation to skin, and no damage to clothes. Since it does not contain sodium tripolyphosphate salt that affects the ecological environment, it does not pollute the environment.

[0007] The above existing sweat treatment measures for fabrics corresponding to the human body sweating a lot by different technical means are summarized as follows: 1. Use laminated fabrics to quickly absorb and discharge human sweat; 2. Add reagents and use post-finishing processes to make sweat marks on the surface of clothing leave no trace; 3. For clothes that have sweat marks, use specially formulated washing powder to remove them. These existing technologies generally only discharge sweat quickly, but cannot eliminate sweat marks. Although the use of post-finishing processes can help prevent sweat marks. However, this type of method generally has the problem that the washing fastness of the auxiliary agents is not high, and the function will usually decrease or even disappear after a certain number of washes. At the same time, the material properties and organizational structure of the treated fabric will also be affected. The washing powder cleaning measures with special formulas can only remove sweat marks at a later stage, and do not affect their formation.

[0008] Therefore, the existing technologies cannot fundamentally solve the problem of sweat marks on fabrics. Therefore, the applicant has developed a fabric that helps to reduce the display of sweat marks after long-term production practice and scientific research to fill the gap in the existing technology. Summary of the invention

[0009] The object of the present invention is to provide a fabric that helps to reduce the display of sweat marks, which can improve the comfort after sweating, reduce the adhesion to the skin and produce a visual effect of reduced sweat marks.

[0010] To achieve the above-mentioned object, the present invention provides a fabric that helps to reduce the display of sweat marks, comprising a fabric body, the fabric body comprising at least one yarn Y1, wherein: the fabric body comprises a clothing surface visual interference layer (L1), a moisture diffusion layer (L2), and a skin-contacting surface visual interference layer (L3);

[0011] The clothing surface visual interference layer (L1) is a non-continuous 3D structure in the warp or weft direction and is arranged at intervals of first basic units, wherein the first basic unit comprises a first protrusion, the height of the first protrusion is H1, the width of the first protrusion is W1, the interval width between two adjacent first protrusions is W2, 0.5≤W2 / H1≤1.5, and 0.5≤W1 / W2≤3.5;

The second basic unit includes a second protrusion, the height of the second protrusion is H3, the width of the second protrusion is W3, and the interval width between two adjacent second protrusions is W4.

[0014] Preferably, the present invention helps to reduce the sweat mark in the fabric where H1≥0.05mm and H3≥0.05mm.

[0015] Preferably, in the fabric that helps to reduce the display of sweat marks of the present invention, the yarn Y1 is a non-transparent yarn and the moisture regain of the yarn Y1 is lower than 5%; or the yarn Y1 is a fiber with a water-repellent structure.

[0016] Preferably, the fabric body in the fabric that helps to reduce the display of sweat marks of the present invention is one of single-sided basic structural fabric, single-sided jacquard structural fabric, double-sided basic structural fabric, double-sided jacquard structural fabric or spacer fabric.

[0017] Preferably, in the fabric that helps to reduce the display of sweat marks of the present invention, the fabric body is a single-sided basic structural fabric or a single-sided jacquard structural fabric, and the surface contact angle of the yarn in the skin-contacting visual interference layer (L3) is less than 70°; the fabric body is a double-sided basic structural fabric or a double-sided jacquard structural fabric, the surface contact angle of the yarn in the garment surface visual interference layer (L1) is less than 160°, and the surface contact angle of the yarn in the skin-contacting visual interference layer (L3) is less than 70°.

[0018] Preferably, the moisture diffusion layer (L2) in the fabric that helps to reduce the display of sweat marks of the present invention is a hydrophilic fiber, and the fiber surface contact angle of the hydrophilic fiber is ≤70°; preferably, the fiber surface contact angle of the hydrophilic fiber is ≤45°.

[0019] Preferably, the present invention helps to reduce the sweat mark showing that W1=W2 in the fabric.

[0020] Preferably, the yarn Y1 in the fabric that helps to reduce the display of sweat marks of the present invention is a non-transparent synthetic fiber yarn with a core-sheath structure or a special-shaped cross-section structure.

[0021] Preferably, the fabric body in the fabric that helps to reduce the display of sweat marks of the present invention also includes yarn Y2 and yarn Y3, the yarn Y1 is arranged on the visual interference layer (L1) on the clothing surface, the yarn Y2 is arranged on the moisture diffusion layer (L2), and the yarn Y3 is arranged on the visual interference layer (L3) on the skin-contacting surface.

[0022] Preferably, the yarn Y2 and the yarn Y3 in the fabric that helps to reduce the display of sweat marks of the present invention are the same.

[0023] Compared with the prior art, the present invention helps to reduce the sweat marks on the fabric, thus filling the gap in the prior art. Therefore, the sweat marks on the fabric are described in detail as follows:

[0024] In real life, adding a drop of water to a dry fabric will form a watermark. This is because the refractive index of water molecules to light is different from that of fabric fibers, resulting in refraction and reflection of light.

[0025] When a drop of water falls on a dry fabric, an interface is created between the water molecules and the fabric fibers. Because the refractive index of water is greater than that of the fiber, light will be refracted after entering the water drop. When the light is refracted from the inside of the water drop, it will be reflected on the surface of the fabric. These reflected rays will form bright spots on the fabric surface, and at the same time form a light and dark contrast with the surrounding fabric (the place without bright spots is dark). The light and dark contrast formed by these bright spots constitutes the watermark we see. When the water molecules evaporate from the fabric surface, the watermark will disappear. The distribution and shape of the water molecules on the fabric depends on factors such as the shape of the fabric surface and the interaction force between the fibers.

[0026] Theoretically, when light passes from one medium to another, the speed of light passing through the two media is different due to the different refractive indices, and the propagation direction of the light will also change due to the difference in refractive indices. This phenomenon is called the refraction of light. The principle of light refraction can be described by Snell's Law. Snell's Law shows that when light passes from one medium to another, the ratio of the sine value of the incident angle and the sine value of the refractive angle is equal to the ratio of the refractive indices of the two media, that is, sin (incident angle) / sin (refraction angle) = n2 / n1; where n1 and n2 represent the refractive indices of the two media respectively.

[0027] According to Snell's law, when light is emitted from a denser medium (such as water or glass) to a less dense medium (such as air), the angle of refraction is smaller than the angle of incidence; and when light is emitted from a less dense medium to a denser medium, the angle of refraction is larger than the angle of incidence. Especially for chemical fibers, when clothes are wet, the presence of water makes the fibers more transparent, and the refractive index of water is different from that of air, so it will scatter light irregularly, resulting in the observed color of the clothes being different from that in the dry state.

[0028] Analyzing the principle of sweat mark formation, we can break it down into two situations:

[0029] The first case is the process of sweat wetting and diffusion on the fabric surface. The reason why sweat marks are visible in this process is that part of the fabric surface is wetted. Compared with the non-wetted part, the wetted part has changed the refractive index of light in the wetted part, so we can see the wetted area, thus forming a white sweat mark formed by the accumulation of salt and protein in the sweat around it.

[0030] The second situation is that sweat wets the surface of the fabric and diffuses on the surface. As time goes by, the sweat evaporates, and the salt and protein in the sweat accumulate around it to form white sweat marks.

[0031] It can be seen that the present invention forms a fabric body with a logical three-layer structure through the visual interference layer (L1) on the clothing surface, the moisture diffusion layer (L2) and the visual interference layer (L3) on the skin surface. At the same time, the present invention effectively improves the comfort after sweating through the discontinuous 3D structure formed by the second protrusions arranged at intervals in the visual interference layer (L3) on the skin surface, reduces the contact area between the fabric skin surface and the skin, and reduces the adhesion between the fabric and the skin after sweating. The present invention allows sweat to diffuse and moisten in the moisture diffusion layer (L2) located in the middle layer of the fabric through the moisture diffusion layer (L2) arranged in the middle. The present invention forms a discontinuous 3D structure through the first protrusions arranged at intervals in the visual interference layer (L1) on the clothing surface, and the process of sweat transfer formed on the fabric clothing surface is visually shielded, thereby achieving a visual effect of reduced sweat marks. It can be seen that the present invention reduces the amount of sweat reaching the clothing surface of the fabric (the visual interference layer on the clothing surface) and reduces the diffusion of sweat on the clothing surface while ensuring comfort, and effectively achieves the purpose of the fabric of the present invention being able to improve the comfort after sweating, reduce the adhesion to the skin, and produce a visual effect of weakened sweat marks. The fabric has strong practicality and is very suitable for wide promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

It can be seen that the present invention reduces the amount of sweat reaching the clothing surface of the fabric (i.e., the visual interference layer L1 on the clothing surface) and reduces the diffusion of sweat on the clothing surface while ensuring comfort, and effectively achieves the purpose of the fabric of the present invention being able to improve the comfort after sweating, reduce adhesion to the skin, and produce a visual effect of weakened sweat marks. The fabric is highly practical and is very suitable for widespread promotion and use.

[0038] Preferably, the present invention helps to reduce the perspiration marks in the fabric where H1≥0.05mm and H3≥0.05mm.

[0039] Preferably, the yarn Y1 in the fabric that helps to reduce the display of sweat marks of the present invention is a non-transparent yarn, and the moisture regain of the yarn Y1 is less than 5%. Specifically, the yarn Y1 of the present invention is a synthetic fiber or a fiber with a water-repellent structure. Among them, when the yarn Y1 is a synthetic fiber, it is preferably a non-transparent synthetic fiber yarn with a core-skin structure or a special-shaped cross-section structure.

Wherein, when the fabric body is single-sided basic structure fabric or single-sided jacquard structure fabric, the surface contact angle of the yarn in the skin-contacting visual interference layer L3 is less than 70°. When the fabric body is double-sided basic structure fabric or double-sided jacquard structure fabric, the surface contact angle of the yarn in the clothing surface visual interference layer L1 is less than 160°, and the surface contact angle of the yarn in the skin-contacting visual interference layer L3 is less than 70°.

[0041] Preferably, the moisture diffusion layer L2 in the fabric that helps to reduce the display of sweat marks of the present invention is a hydrophilic fiber, and the fiber surface contact angle of the hydrophilic fiber is ≤70°; preferably, the fiber surface contact angle of the hydrophilic fiber is ≤45°, which helps the diffusion of sweat.

[0042] Preferably, the fabric body of the fabric that helps to reduce the display of sweat marks of the present invention further includes yarn Y2 and yarn Y3, the yarn Y1 is arranged on the visual interference layer L1 on the clothing surface, the yarn Y2 is arranged on the moisture diffusion layer L2, and the yarn Y3 is arranged on the visual interference layer L3 on the skin-contacting surface. Specifically, the yarn Y2 is the same as the yarn Y3, that is, the moisture diffusion layer L2 and the visual interference layer L3 on the skin-contacting surface use the same yarn.

[0043] Embodiment 1:

[0044] Combination Figure 1 and Figure 2As shown, the fabric that helps to reduce the display of sweat marks in this embodiment is a single-sided basic structure weft knitted fabric, and its three-layer logical structure consists of the outermost clothing surface visual interference layer L1, the middle layer of the moisture diffusion layer L2 for the diffusion and moistening of sweat, and the innermost skin-contacting surface visual interference layer L3. The fabric of this embodiment uses a yarn Y1, which is made of two yarns of 50D / 36F polyester fiber with a skin-core structure. The regain of the polyester fiber is 0.4%. The surface contact angle of liquid water with the yarn Y1 on the clothing surface visual interference layer L1 is 55°. A 28G knitting circular machine is used for weaving, and the three-layer logical structure of the fabric is formed by the weaving process of double threading of the yarn. In this embodiment, the height H1 of the first raised portion A1 in the visual interference layer L1 of the clothing surface is 0.25 mm, and the width of the interval between the two adjacent first raised portions A1 is W2=0.16 mm. Liquid water begins to diffuse from the skin-contacting visual interference layer L3. When the liquid water diffuses through the moisture diffusion layer L2 to the clothing surface visual interference layer L1, the water evaporates in the interval W2 between the two adjacent first raised portions A1. The fabric W2 / H1 of this embodiment is 0.64. In the natural state, because the refractive index of water molecules to light is different from the refractive index of fabric fibers, light refraction and reflection are formed. When water drops on dry fabrics, water molecules will form an interface with fabric fibers. Because the refractive index of water is greater than that of fibers, light will refract after entering the water droplets. When light is refracted from the inside of the water droplets, it will reflect on the fabric surface. When water molecules evaporate from the fabric surface, the watermark will disappear, thereby visually achieving the effect of reducing the visibility of sweat marks. According to the anti-perspiration performance test method in the T / CNTAC 56-2020 group standard "General Technical Requirements for Functional Evaluation of Textiles", the water absorption of the skin-contacting visual interference layer L3 and the color change of the clothing-side visual interference layer L1 in this embodiment are Class D as described in the droplet type description in GB / T 19977. The droplets are completely wetted and disappear within 30 seconds.

[0045] Embodiment 2:

[0046] Combination Figure 1 and Figure 3In this embodiment, the fabric that helps to reduce the display of sweat marks is a single-sided basic structure weft knitted fabric, and its three-layer logical structure consists of the outermost clothing surface visual interference layer L1, the middle layer of the moisture diffusion layer L2 for the diffusion and moistening of sweat, and the innermost skin-contacting surface visual interference layer L3. The fabric of this embodiment uses two identical yarns Y1, and the yarn Y1 is made of two yarns of 50D / 36F polyester fiber with a skin-core structure. The regain of the polyester fiber is 0.4%. The contact angle between liquid water and the yarn surface on the clothing surface visual interference layer L1 is 120°, and the contact angle between the yarn surface of the skin-contacting surface visual interference layer L3 is 60°. A 32G knitting circular machine is used for weaving, and the three-layer logical structure of the fabric is formed by the weaving process of the needle disc and the needle cylinder yarns being separately threaded. In this embodiment, the height H1 of the first raised portion A1 in the visual interference layer L1 of the clothing surface is 0.24 mm, and the width of the interval between the two adjacent first raised portions A1 is W2=0.14 mm. Liquid water begins to diffuse from the skin-contacting visual interference layer L3. When the liquid water diffuses through the moisture diffusion layer L2 to the clothing surface visual interference layer L1, the water evaporates in the interval W2 between the two adjacent first raised portions A1. The fabric W2 / H1 of this embodiment is 0.58. In a natural state, because the refractive index of water molecules to light is different from that of fabric fibers, refraction and reflection of light are formed. When water droplets are on dry fabrics, an interface is formed between the water molecules and the fabric fibers. Because the refractive index of water is greater than that of fibers, light will be refracted after entering the water droplets. When light is refracted from the inside of the water droplets, it will reflect on the surface of the fabric. When the water molecules evaporate from the surface of the fabric, the watermark will disappear, thereby visually achieving the effect of reducing the visibility of sweat marks. According to the anti-perspiration performance test method in the T / CNTAC 56-2020 group standard "General Technical Requirements for Functional Evaluation of Textiles", the water absorption of the skin-contacting visual interference layer L3 and the color change of the clothing-side visual interference layer L1 in this embodiment are Class D as described in the droplet type description in GB / T19977. The droplets are completely wetted and disappear within 30 seconds.

Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any figure mark in the claims should not be regarded as limiting the claims involved. At the same time, what is disclosed above is only the preferred embodiment of the present invention, and of course it cannot be used to limit the scope of the rights of the present invention.
