Description

Technical Field

[0001] The invention relates to the technical field of clothing fabrics, and in particular to a wool-resistant sports yoga fabric and a preparation method thereof. Background Art

[0002] As people's health awareness increases, consumers' demand for sportswear increases, especially sports yoga clothing, including sports tops, T-shirts, sports shorts, sports trousers, sports dresses and other styles, which have become popular and trendy items in daily life. They are widely used and worn in many scenes. Sports yoga clothing can be worn at work, outdoors, sports, and life. There is a group of pet owners who pursue a fashionable life. When they come into contact with pets in life, pet hair is easy to stick to clothing, and it is difficult to get rid of it. The sticky hair phenomenon is very obvious. This is because yoga-type fabrics are mainly elastic double-sided fabrics made of synthetic fibers such as polyester and nylon. They have the advantages of high strength, good elasticity, and quick drying, which are suitable for sports-type clothing. However, ordinary synthetic fibers have poor moisture absorption, and are easy to accumulate static electricity and are not easy to be discharged. In addition, the front and back of the fabric are sanded. When the pet rolls on the pet owner, the friction causes static electricity, which absorbs the hair feathers and easily sticks to the hair, affecting the appearance of the clothing. Especially in spring and autumn when pets shed hair, the trouble of sticking hair is more troubling for pet owners, so anti-sticky sports yoga fabrics are widely needed in the market.

[0003] Although there are anti-stick wool fabrics made of polyester or nylon, which can improve static electricity and improve the anti-stick wool effect by adding anti-static additives, the added anti-static agent has poor durability due to its weak binding force with the fabric. Generally, it loses its anti-static effect after multiple washings. When the anti-static function weakens, the anti-stick wool effect of the fabric becomes worse, and the anti-stick wool effect is not ideal and not lasting.

[0004] Therefore, there is a need for a hair-resistant sports yoga fabric and a preparation method thereof to solve the pain points of consumers being easily hair-sticky and difficult to clean when wearing the fabric, and to meet consumer demand. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an anti-hair-sticking sports yoga fabric and a preparation method thereof, which solves the problem that hair is easily stuck to the fabric and is difficult to clean when worn by consumers.

[0006] The technical solution of the present invention is achieved in this way:

[0007] A non-stick wool sports yoga fabric comprises a first yarn and a second yarn, wherein the first yarn comprises a nylon filament with a hygroscopicity of 5-6%, the second yarn comprises a polyester filament with a hygroscopicity of 1-2%, the first yarn and the second yarn are woven into a fabric with a double-sided structure with a third yarn as an intermediate layer, the first yarn serves as an outer layer of the fabric, the second yarn serves as an inner layer of the fabric, and the third yarn comprises a spandex filament.

[0008] Preferably, the first yarn is nylon filament FDY.

[0009] Preferably, the first yarn comprises modified nylon filament FDY, bio-based nylon filament FDY or special-section nylon filament FDY.

[0010] Preferably, the special-shaped cross-section nylon filament FDY has a hexalobal cross-section.

[0011] Preferably, the second yarn comprises a polyester filament DTY with a special cross-section;

[0012] Alternatively, the second yarn includes modified polyester filaments DTY embedded with hydrophilic groups and soft segments.

[0013] Preferably, the second yarn comprises cationic dye-dyable polyester filament DTY or normal temperature and pressure dyeable polyester filament DTY.

[0014] Preferably, a hydrophilic stain-release finishing agent is added to the fabric during the post-finishing and shaping process.

[0015] Preferably, the hydrophilic stain-release finishing agent is one or more of polyurethane, polyvinyl alcohol, and polyacrylate.

[0016] Preferably, the fabric has an air layer structure.

[0017] Another object of the present invention is to provide a method for preparing anti-hair sports yoga fabric, the preparation method comprising the following steps: weaving the embryo → opening the edge → shaping the embryo fabric → dyeing → post-finishing and shaping;

[0018] The weaving process includes: feeding the second yarn to the upper needle plate of the weft knitting double-sided circular knitting machine and knitting all the yarns into loops to form the inner layer of the fabric, feeding the first yarn to the lower needle plate of the weft knitting double-sided circular knitting machine and knitting all the yarns into loops to form the outer layer of the fabric, and knitting the third yarn to form the middle layer of the fabric by tucking every other yarn on the upper needle plate and the lower needle plate respectively, and connecting the outer layer and the inner layer of the fabric;

[0019] The post-finishing process includes: adding a hydrophilic, easy-to-clean finishing agent to the fabric for finishing.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) The electrical conductivity of water is higher than that of general metal conductors. For example, the volume resistivity of pure water is 10 6 Ω·cm, because water has a very high conductivity, so as long as a small amount of water is absorbed, the conductivity of the polymer material can be significantly improved. Therefore, in the anti-sticking hair sports yoga fabric of the present application, the outer layer includes nylon filaments with a hygroscopicity of 5-6%, and the inner layer includes polyester filaments with a hygroscopicity of 1-2%. Compared with ordinary nylon and polyester, the hygroscopicity is stronger, which can greatly improve the hygroscopicity and moisture content of the fabric. The water is stored and conducted in the fiber and the fabric, thereby improving the conductive performance of the fabric, reducing the static electricity phenomenon, and then improving the anti-sticking hair performance of the fabric;

[0022] (2) The hygroscopicity of the outer layer of the fabric is higher than that of the inner layer. When the human body sweats, the inner layer absorbs the body's moisture and transfers it to the outer layer. The moisture is quickly transferred from the inner layer to the outer layer. The sweat forms a wetting gradient between the inner and outer layers, which promotes the transfer of moisture from the inside to the outside of the fabric. The moisture content of the outer layer of the fabric can be continuously maintained, so that the outer layer of the fabric has a higher moisture content and thus maintains better antistatic properties, thereby further improving the anti-hair-sticking performance of the fabric. At the same time, the conduction of sweat can also improve the comfort and breathability of the fabric, reduce the accumulation of sweat, and keep the skin dry. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] A non-stick wool sports yoga fabric comprises a first yarn and a second yarn, wherein the first yarn comprises a nylon filament with a hygroscopicity of 5-6%, the second yarn comprises a polyester filament with a hygroscopicity of 1-2%, the first yarn and the second yarn are woven into a fabric with a double-sided structure with a third yarn as an intermediate layer, the first yarn serves as an outer layer of the fabric, the second yarn serves as an inner layer of the fabric, and the third yarn comprises a spandex filament.

[0028] Hygroscopicity is one of the indicators of the physical properties of fibers. The ability of fiber materials to absorb moisture from a gaseous environment is usually called hygroscopicity, which refers to the ability of materials to absorb moisture in the air. Generally, moisture regain is used to indicate the strength of fiber hygroscopicity. At present, the hygroscopicity of conventional polyester and nylon yoga fabrics, conventional nylon 6 and nylon 66 are 3.5-4.5%, and the hygroscopicity of conventional polyester is 0.3-0.4%.

[0029] Under standard conditions (65% RH, 20°C), the resistivity of nylon 6 and nylon 66 is about 10 11～15 Ω·cm, the resistivity of some nylon after antistatic treatment is still 10 11～12 Ω·cm, which is difficult to improve, and the resistivity of the fabric is also difficult to reach 10 9 Ω·cm and durable. High-quality antistatic fiber has a resistivity of less than 10 9 Ω·cm, and generally in 10 6～9 Ω·cm are all anti-static materials. The accumulation of static electricity is related to the conductivity of the material. When expressed in terms of resistivity, the smaller the resistivity of the material, the better the conductivity and the less likely static electricity is to accumulate. When the resistivity of the material is less than 10 6 Ω·cm, because of its good conductivity, static electricity leaks quickly. The material resistivity is greater than 10 16 Ω·cm or less than 10 9 Ω·cm is not easy to generate static electricity, and the resistivity is 10 11～16 Materials with a resistance of Ω·cm are most likely to generate static electricity.

[0030] The electrical conductivity of water is higher than that of ordinary metal conductors. For example, the volume resistivity of pure water is 10 6 Ω·cm, because water has a very high conductivity, so as long as a small amount of water is absorbed, the conductivity of the polymer material can be significantly improved, thereby improving the moisture absorption capacity of the fiber material. In the anti-sticking wool sports yoga fabric of this scheme, the outer layer includes nylon filaments with a hygroscopicity of 5-6%, and the inner layer includes polyester filaments with a hygroscopicity of 1-2%. Compared with ordinary nylon and polyester, the hygroscopicity is stronger, which can greatly improve the hygroscopicity and moisture content of the fabric. The water is stored and conducted in the fiber and the fabric, thereby improving the conductive performance of the fabric, reducing the static electricity phenomenon, and then improving the anti-sticking wool performance of the fabric.

[0031] Secondly, the hygroscopicity of the outer layer of the fabric is higher than that of the inner layer. When the human body sweats, the inner layer absorbs the body's moisture and transfers it to the outer layer. The moisture is quickly transferred from the inner layer to the outer layer. The sweat forms a wetting gradient through the inner and outer layers to promote the transfer of moisture from the inside to the outside of the fabric. The moisture content of the outer layer of the fabric can be continuously maintained, so that the outer layer of the fabric has a higher moisture content and maintains better anti-static properties, thereby further improving the anti-sticking performance of the fabric. At the same time, the conduction of sweat can also improve the comfort and breathability of the fabric, reduce the accumulation of sweat, and keep the skin dry.

[0032] Preferably, the first yarn is nylon filament FDY, because the fabric not only absorbs external pet hair and various hairiness when in use, but also has the precipitation of the fabric fiber hairiness caused by static electricity during friction. Therefore, it is necessary to have an anti-sticking function, and in addition to improving the antistatic property, the fabric smoothness should also be improved. The full name of FDY is Fully drawn yarn, which is to introduce a stretching effect during the spinning process to obtain a winding yarn with high orientation and medium crystallinity. The FDY fiber is in a relaxed state, and the fiber is straight without shrinkage. The woven fabric feels smooth and soft, and is often used to weave simulated silk fabrics. The use of filament FDY can make the outer surface of the fabric smooth and smooth, thereby reducing the precipitation of the fabric fiber hairiness during friction. The nylon filament FDY with smoothness is used as the fabric surface. Through the double-sided structure weaving method, the middle spandex connecting wire keeps the fabric at a high density. The fabric surface is smooth and smooth, effectively reducing friction, smooth and not easy to stick hair, and easy to fall off after sticking hair.

[0033] Preferably, the first yarn is modified nylon filament FDY, bio-based nylon filament FDY or special-section nylon filament FDY. The hygroscopicity of modified nylon filament FDY is 5-6%, the hygroscopicity of bio-based nylon FDY is 5.5-6%, and the hygroscopicity of special-section nylon such as hexalobal nylon filament FDY is 5-5.2%, which can improve the hygroscopicity of the outer layer of the fabric.

[0034] Preferably, the second yarn comprises polyester filament DTY with a special cross-section, such as a trilobal shape, a cross shape, etc., and its hygroscopicity is 1.0-1.4%;

[0035] Alternatively, the second yarn includes a modified polyester filament DTY embedded with a hydrophilic group and a soft segment, and its hygroscopicity is 1.4 to 2.0%. Conventional polyester has poor hygroscopicity, but by introducing hydrophilic groups and soft segments, the moisture absorption and moisture conduction capacity of the fiber can be improved, thereby making the skin-friendly side of the fabric soft, comfortable and breathable. Preferably, it is a polyester filament DTY dyeable with cationic dyes or a polyester filament DTY dyeable at room temperature and pressure. In addition, the full name of DTY is Draw textured yarn, also called polyester low-elastic yarn, which uses POY as the raw yarn, and is continuously or simultaneously stretched on a texturing machine and false-twisted and deformed by a twister. The yarn is still straight when wound, but in a relaxed state, it will shrink and become fluffy, in a curled state, with a certain elasticity and shrinkage. The DTY fabric will be softer and fluffier, making the inner layer of the fabric more comfortable;

[0036] During the wearing process, fabrics form dirt due to the absorption of dust in the air, human secretions and contamination. In particular, synthetic fibers and their blended fabrics are prone to static electricity and dirt absorption. Due to poor surface hydrophilicity, water is not easy to penetrate into the gaps between fibers during washing, and dirt is difficult to remove. Preferably, a hydrophilic easy-to-remove finishing agent is added to the fabric during the post-finishing and shaping process, which can enhance the moisture absorption and perspiration effect of the fabric, increase the hydrophilicity of the fiber surface, and increase the moisture on the surface of the fabric, thereby improving the antistatic effect. Secondly, the finishing agent has the characteristic of easy decontamination, and the increase in hydrophilicity makes it easy for water to penetrate into the gaps between fibers during washing, making it easy to remove dirt. Even if it is sticky or contaminated by pollutants, it can be easily washed or even wiped off.

[0037] Among them, the hydrophilic easy-to-decontamination finishing agent is preferably APA liq, FCK002, One or more of FCK066. These hydrophilic easy-to-decontamination finishing agents can form a layer of hydrophilic polymer film on the surface of the fabric, increase the hydrophilicity of the fiber surface, and at the same time form a hydrophilic film on the surface of the fabric, covering the fiber and blocking the gaps between the fibers, inhibiting the precipitation of fiber hairiness, playing a role in keeping the fabric smooth, making the surface layer easy to wet and swell, and increasing the antistatic property of the fabric, thereby effectively reducing friction and hairiness. APA liq was purchased from Archroma, FCK002 and FCK066 was purchased from Deconami Company.

[0038] Preferably, the fabric has an air layer structure, and the outer and inner layers of fabric are connected together by a loop structure to form an air layer. Due to the presence of the air layer, the fabric is softer, more comfortable, and has better skin-friendliness. In addition, the overall strength of the fabric is higher and the durability is better, which is conducive to application in yoga fabrics.

[0039] In the fabric, the content of the first yarn is 40-45% by weight, the content of the second yarn is 40-45% by weight, and the content of the third yarn is 10-20% by weight. When the content of the third yarn in the middle layer is 10-20% by weight, the content is moderate, so that the fabric can maintain a certain air permeability, so that even during exercise or activities, the fabric can effectively wick sweat and keep the skin dry.

[0040] The design model of the fabric of the present invention is shown in Figure 1 .

[0041] The method for preparing the above-mentioned anti-sticking wool sports yoga fabric comprises the following steps: weaving the embryo→cutting the edge→setting the embryo fabric→dyeing→post-finishing and setting the fabric;

[0121] In Example 5, the first yarn and the second yarn have good hygroscopicity, but the first yarn is DTY, which is not as smooth as the FDY yarn. Compared with Examples 1-4, the fabric has good hydrophilicity and antistatic properties, but the fabric is slightly less smooth. The degree of hair sticking is: a small amount of hair sticking, and the anti-hair sticking performance is average;

[0122] Comparative Example 1 is a conventional nylon yoga fabric on the market. No hydrophilic easy-to-decontamination finishing agent is added. The front of the fabric is made of conventional nylon DTY, and double-sided sanding is done. The fabric has poor smoothness and poor anti-hair performance. The results of the anti-hair performance test of the fabric in Comparative Example 1 are shown in Figure 3 , the white filaments in the picture are pet hair;

[0123] Comparative Example 2 is a conventional nylon yoga fabric on the market, which is not sanded and has a hydrophilic and easy-to-decontamination finishing agent. The conventional nylon DTY has average moisture absorption, the DTY surface is not smooth, the antistatic performance before washing is average, and the antistatic performance after washing is poor; the anti-hair-sticking performance is average;

[0124] Comparative Example 3: conventional polyester yoga fabric on the market, with a hydrophilic easy-to-decontamination finishing agent added, the hygroscopicity of polyester is only 0.4%, which is poor. The front of the fabric is made of conventional nylon DTY, and double-sided sanding is done. The fabric has poor smoothness and poor anti-hair performance.

[0125] Comparative Example 4, compared with Example 1, no hydrophilic easy-to-decontamination finishing agent was added, but double-sided sanding was performed, and the fabric had poor smoothness and poor anti-hair-sticking performance;

[0126] Comparative Example 5: Compared with Example 1, the inner layer is made of conventional polyester. Although the fabric is smooth and comfortable, the hygroscopicity of the inner layer is poor, and the hygroscopicity of the outer layer is not improved. The anti-hair-sticking performance is average.

[0127] Comparative Example 6, compared with Example 1, the outer layer adopts conventional nylon, the fabric has good smoothness, but average moisture absorption and anti-hair performance.

[0128] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
