Description

Knitted fabric and its preparation method and application Technical Field

[0001] The present application relates to the field of fabric technology, for example, a knitted fabric and its preparation method and application. Background Art

[0002] With the improvement of living standards, people's requirements for fabrics are getting higher and higher, especially for underwear fabrics. They are not only required to be comfortable to wear, soft, skin-friendly and beautiful, but also to have good warmth retention and breathability.

[0003] In the related art, methods such as adding layers and thickening are often used to achieve the warmth-retaining effect of close-fitting underwear. For example, CN103222686A discloses a thermal wool underwear fabric, comprising an underwear surface layer, an underwear base layer, a wool layer, a reinforcement layer, an elastic layer, and a protective layer. The wool layer is sewn to the interior of the protective layer using a sewing machine. The reinforcement layer is adhesively bonded to the protective layer around its perimeter. The reinforcement layer and the elastic layer are respectively knitted together as a warp and weft yarn. The underwear base layer is sewn to the lower surface of the reinforcement layer, and the underwear surface layer is sewn to the upper surface of the reinforcement layer. This multi-layer composite method achieves cold protection and warmth; however, this increases the weight of the fabric, resulting in poor comfort and breathability.

[0004] Another related technique involves planting staple fibers for clothing on plastic film to form a needle-punched nonwoven fabric, then gluing clothing fabric on both sides, and then cutting and sewing it to create thermal underwear. However, the resulting fabric has poor elasticity and air permeability, resulting in poor wearing comfort and warmth retention, and the clothing has a short lifespan.

[0005] Therefore, developing a fabric that has good warmth retention and breathability, good moisture absorption and dimensional stability after washing, and is comfortable to wear and antibacterial, especially suitable for underwear, is an urgent problem to be solved in this field.

[0006] Summary of the Invention

[0007] The following is a summary of the subject matter described in detail herein. This summary is not intended to limit the scope of the claims.

[0008] The present application provides a knitted fabric, a preparation method, and an application thereof. The knitted fabric adopts specific materials and structural design, and the resulting fabric has good warmth retention and breathability, good moisture absorption and dimensional stability after washing. The fabric is also comfortable to wear and antibacterial, making it particularly suitable for underwear.

[0009] In a first aspect, the present application provides a knitted fabric, wherein the yarn of the knitted fabric comprises a blended yarn of wool and Tencel; and the knitted fabric has a horizontal striped false terry structure.

[0010] In this application, the yarn of the knitted fabric is a blended yarn of wool and Tencel. Wool has good water absorption, which makes the fabric hydrophilic and increases wearing comfort. Wool also has a natural curly structure, which can form many stagnant air zones as barriers, increasing the warmth retention of the fabric. Fabrics containing Tencel have good dimensional stability after washing and high hygroscopicity. They can act as a moisture-conducting carrier, directing sweat away from the body, thereby making the body feel extremely comfortable and having a soft luster. At the same time, the false terry structure is a structure that looks like terry on the surface, but is not actually a true terry structure. It is designed with the help of different triangles and needles to produce a terry-like effect, with a soft and comfortable feel and good thermal insulation performance. On the basis of false terry, a horizontal false terry structure is adopted, combined with wool and Tencel blended yarn, so that the resulting fabric has multiple functions of hydrophilicity, warmth retention, antibacterial, and breathability, and is comfortable to wear and can be used as a fabric for underwear.

[0011] In one embodiment, the blending mass ratio of the wool and Tencel blended yarn is (25-55):(45-75), wherein the specific values ​​in (25-55) can be, for example, 25, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52, 54, 55, etc.; the specific values ​​in (45-75) can be, for example, 45, 46, 48, 50, 52, 54, 56, 58, 60, 62, 64, 66, 68, 70, 72, 74, 75, etc.

[0012] In one embodiment, the wool and Tencel blended yarn has a count of 30 to 40 N / 1.

[0013] In one embodiment, the wool and tencel blended yarn comprises wool and tencel compact yarn.

[0014] In this application, if other blended yarns are used, such as wool and polyester blends, the warmth retention, breathability and wearing comfort of the fabric will deteriorate.

[0015] In one embodiment, the knitted fabric includes drawstring stripes and napped stripes.

[0016] In one embodiment, the drawn stripes and the napped stripes are arranged at intervals.

[0017] In one embodiment, the width of the draw strip is 1 to 8 mm, for example, it can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 4.5 mm, 5 mm, 5.5 mm, 6 mm, etc.

[0018] In one embodiment, the width of the roughening is 4 to 8 mm, for example, it can be 4 mm, 4.2 mm, 4.5 mm, 4.8 mm, 5 mm, 5.2 mm, 5.5 mm, 5.8 mm, 6 mm, 6.2 mm, 6.5 mm, 6.8 mm, 7 mm, 7.2 mm, 7.5 mm, 7.8 mm, 8 mm, etc.

[0019] In the present application, when the width of the strips and the napping is within the above-defined range, the resulting fabric has better thermal insulation performance and can achieve the organizational structure of horizontal striped false terry; when the napping width is certain, the strip width is too small, which does not meet the structural design of the horizontal striped false terry, and the air permeability of the fabric is poor; when the strip width is too large, the density of terry per square meter is reduced, resulting in reduced thermal insulation.

[0020] In one embodiment, the padding ratio of the knitted fabric is 1:(0.5-4), for example, it can be 1:0.5, 1:0.6, 1:0.8, 1:1, 1:1.2, 1:1.5, 1:1.8, 1:2, 1:2.2, 1:2.4, 1:2.6, 1:2.8, 1:3, 1:3.2, 1:3.5, 1:3.8, 1:4, etc.

[0021] In the present application, when the padding ratio is within the above range, the resulting fabric has better thermal insulation and is more conducive to the subsequent napping process; when the padding ratio is too large, the pile loops are smaller, the hair is not easily pulled out, the pulled hair is relatively sparse, and the thermal insulation is poor.

[0022] In one embodiment, the loop length of the knitted fabric is 13 to 16 cm / 50N, for example, it can be 13 cm / 50N, 13.2 cm / 50N, 13.5 cm / 50N, 13.8 cm / 50N, 14 cm / 50N, 14.2 cm / 50N, 14.5 cm / 50N, 14.8 cm / 50N, 15 cm / 50N, 15.2 cm / 50N, 15.5 cm / 50N, 15.8 cm / 50N, 16 cm / 50N, etc.

[0023] In this application, the loop length is too short, the fabric weight is heavy, it has no elasticity, and it is not conducive to weaving. The friction during weaving is relatively large, which causes great damage to the knitting needles. The loop length is too long, the fabric has poor warmth retention, poor windproof effect, and poor fabric shrinkage.

[0024] In one embodiment, the tuck coil length of the knitted fabric is 4 to 8 cm / 50N, for example, it can be 4 cm / 50N, 4.2 cm / 50N, 4.4 cm / 50N, 4.6 cm / 50N, 4.8 cm / 50N, 5 cm / 50N, 5.2 cm / 50N, 5.4 cm / 50N, 5.6 cm / 50N, 5.8 cm / 50N, 6 cm / 50N, 6.2 cm / 50N, 6.4 cm / 50N, 6.6 cm / 50N, 6.8 cm / 50N, 7 cm / 50N, 7.2 cm / 50N, 7.4 cm / 50N, 7.6 cm / 50N, 7.8 cm / 50N, 8 cm / 50N, etc.

[0025] In this application, the length of the tuck loop is too small, the yarn tension is high, it is easy to break, holes appear, and weaving is difficult; the length of the loop loop is too long, resulting in the knitting needle not being able to pick up the yarn, yarn skipping occurs, the pulled out hair is relatively hollow, and the warming effect is poor.

[0026] In a second aspect, the present application provides a method for preparing the knitted fabric according to the first aspect, the preparation method comprising:

[0027] The wool and Tencel blended yarns are knitted and napped to obtain a knitted fabric with a horizontal striped false terry structure.

[0028] In one embodiment, the rotation speed of the loom is 10 to 30 r / min, for example, it can be 10 r / min, 12 r / min, 15 r / min, 18 r / min, 20 r / min, 22 r / min, 25 r / min, 28 r / min, 30 r / min, etc.

[0029] In one embodiment, the roughening includes reverse roughening.

[0030] In a third aspect, the present application provides a garment having a horizontal striped false terry structure, wherein the garment comprises the knitted fabric according to the first aspect.

[0031] In one embodiment, the garment having a horizontal striped false terry structure comprises an undergarment.

[0032] The numerical range described in this application includes not only the point values ​​listed above, but also any point values ​​between the above numerical ranges that are not listed. Due to limited space and for the sake of simplicity, this application no longer exhaustively lists the specific point values ​​included in the range.

[0033] Compared with the related art, the beneficial effects of this application are:

[0034] The knitted fabric provided in this application adopts a horizontal striped false terry structure design and is combined with wool and Tencel blended yarn. The resulting fabric has good warmth retention and breathability, good moisture absorption and dimensional stability after washing. The fabric is comfortable to wear and antibacterial, and is particularly suitable for underwear.

[0059] Performance Testing

[0060] (1) Warmth retention performance: The thermal resistance of the fabrics obtained in Examples 1 to 9 was tested; the specific testing method includes:

[0061] According to GB / T35762-2017 "Test method for thermal transfer properties of textiles - Flat plate method", three 35cm×35cm samples of the obtained fabric were cut and humidified under standard atmospheric conditions for 24 hours. The thermal resistance was then tested using a YG606G thermal and moisture resistance tester, and the average value was taken.

[0062] Among them, “-” means that the yarn is easy to break during the weaving process and cannot be weaved.

[0063] The specific test results are shown in Table 2.

[0064] Table 2

[0065] As can be seen from Table 1, the knitted fabric provided in this application adopts a horizontal striped false terry structure design, combined with wool and Tencel blended yarn, and the resulting fabric has better warmth retention, light weight, comfortable wearing, and good processing performance.

[0066] From the comparison of Examples 1, 2 and 3, it can be seen that if the draw width is too large, the thermal resistance is low and the thermal insulation performance is poor; if the draw width is too small, there is no improvement in the thermal insulation performance, and the stripes of the fabric are not obvious, which does not meet the structural design of the horizontal striped false terry.

[0067] Comparison of Example 1 with Examples 4 and 5 shows that, without a specific padding ratio, the resulting fabric has low thermal resistance and poor thermal insulation performance.

[0068] From the comparison between Examples 1, 6 and 7, it can be seen that if the loop length is too large, the thermal resistance is low and the thermal insulation performance is poor; if the loop length is too small, the thermal insulation performance will not be greatly improved, but the fabric will be heavier, the wearing comfort will be poor, and the machine will be easily damaged.

[0069] Comparison of Examples 1, 8, and 9 shows that if the tuck loop length is outside the specified range, poor thermal insulation performance may result or weaving may be difficult.

[0070] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of this application. It should be understood that the above is only a specific embodiment of this application and is not intended to limit this application.
