Description

Technical Field

[0001] The utility model relates to the field of fabrics, and more specifically, to a warm warp-knitted elastic fabric. Background Art

[0002] At present, the market realizes the warmth retention effect of fabrics through multiple layers. However, since multiple layers are a composite fabric made artificially, its manufacturing process is complex and the manufacturing cycle is long. At the same time, because the multi-layer fabric is not resistant to washing, the warmth retention effect is affected. Also, because the multi-layer fabric is a composite fabric and the elasticity of each layer of fabric is different, the phenomenon of uneven elasticity or tiny elasticity will occur in the whole fabric. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art, and provide a warm warp-knitted elastic fabric. By knitting and combining yarns to form a warmth retention cavity and a warmth retention channel, the multi-layer fabric composite is reduced. The warmth retention cavity stores heat, and the warmth retention channel circulates heat and transfers it to the human body. The warmth retention channel formed by knitting is combined with the wave pattern to form a curve, which can increase the warmth retention area. And combined with the yarns, the fabric forms a bend, so that the yarns are also bent after being knitted well. When the fabric is stretched, the bent yarns can have a tensile force, which increases the elasticity of the fabric and will not cause the fabric to be unstable due to excessive stretching.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] The utility model discloses a warm warp-knitted elastic fabric, which is formed by circular knitting in the width direction with multiple wave zones as units. Each group of the wave zones includes at least two wave patterns arranged in parallel. A warmth retention channel is formed between two adjacent wave patterns. Two adjacent groups of wave zones are symmetrically distributed, and two adjacent groups of wave zones are symmetrically knitted to form a warmth retention cavity.

[0006] Further, each group of wave zones includes four wave patterns arranged in parallel and three warmth retention channels.

[0007] Further, the distance L between two wave crests of the warmth retention cavity is 0.3 cm - 0.8 cm, and the distance H between two wave troughs of longitudinally adjacent warmth retention cavities is 0.4 cm - 0.9 cm.

[0008] Further, the width of each warmth retention channel is one-third of the distance L between two wave crests of the warmth retention cavity, and the width of each wave pattern is one-third of the width of the warmth retention channel.

[0009] Further, the fabric is woven in 86 longitudinal rows, and the weaving tracks of the 1st - 43rd longitudinal columns are symmetrical to those of the 44th - 86th longitudinal columns. The movement track of the front comb of the fabric is 12 - 11 / 11 - 10 / 10 - 9 / 9 - 8 / 8 - 7 / 7 - 6 / 6 - 5 / 5 - 4 / 4 - 3 / 3 - 2 / (2 - 1 / 1 - 2)*5 / 2 - 3 / 3 - 4 / 4 - 5 / 5 - 6 / 6 - 7 / 7 - 8 / 8 - 9 / 9 - 10 / (10 - 11 / 11 - 10)*5, and the movement track of the rear comb of the fabric is 44 - 45 / 45 - 46 / 46 - 47 / 47 - 48 / 49 - 50 / 51 - 52 / 52 - 53 / (53 - 54 / 54 - 53)*5 / 53 - 52 / 52 - 51 / 51 - 50 / 50 - 49 / 49 - 48 / 48 - 47 / 47 - 46 / 46 - 45(45 - 44 / 44 - 45)*5.

[0010] Further, the fabric is woven with 50D / 12F nylon dull fiber and 70D spandex fiber.

[0011] Further, the fabric has a longitudinal density of 34 cpc, a transverse density of 20 wpi, and is woven into a fabric with a gram weight of 280 g / m².

[0012] Further, along the width direction, the wave crest of the heat - preservation cavity in the previous column is opposite to the wave trough of the heat - preservation cavity in the next column, and the wave trough of the heat - preservation cavity in the previous column is opposite to the wave crest of the heat - preservation cavity in the next column.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By using one - piece weaving to replace multi - layer fabric lamination, the process flow is reduced while the cost is reduced. The heat - preservation cavities formed by weaving and combining yarns can store heat and supply it to the human body, and the heat - preservation channels formed by weaving can circulate heat and transfer it to the human body. Since the weaving is curve weaving, the heat - preservation area of the fabric is increased, thereby enhancing the heat - preservation performance of the fabric. Also, due to curve weaving, the yarn can have a buffer during stretching when being woven, so that the fabric has greater elasticity and the yarn will not break due to excessive stretching, causing fabric instability.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figure 1 shown in FIG. -3, a warm warp knitted elastic fabric is formed by circular knitting in the width direction with multiple groups of wave zones 100 as units. The fabric is knitted with 86 wales. The knitting tracks of the 1st - 43rd wales are symmetrical to those of the 44th - 86th wales. The movement track of the front guide bar of the fabric is 12-11 / 11-10 / 10-9 / 9-8 / 8-7 / 7-6 / 6-5 / 5-4 / 4-3 / 3-2 / (2-1 / 1-2)*5 / 2-3 / 3-4 / 4-5 / 5-6 / 6-7 / 7-8 / 8-9 / 9-10 / (10-11 / 11-10)*5, and the movement track of the rear guide bar of the fabric is 44-45 / 45-46 / 46-47 / 47-48 / 49-50 / 51-52 / 52-53 / (53-54 / 54-53)*5 / 53-52 / 52-51 / 51-50 / 50-49 / 49-48 / 48-47 / 47-46 / 46-45(45-44 / 44-45)*5. A single-layer warm warp knitted elastic fabric is knitted to replace the multi-layer composite fabric, thereby reducing the fabric cost while increasing the practicability of the fabric and improving the problem of uneven or tiny elasticity of the multi-layer fabric.

[0021] Each group of wave zones 100 includes at least two wave structures 101 arranged in parallel. A heat preservation channel 102 is formed between two adjacent wave structures 101. In this embodiment, each group of wave zones 100 includes four wave structures 101 and three heat preservation channels 102 arranged in parallel. The existence of the heat preservation channels 102 can better circulate heat and can better transfer heat to the human body. Since the heat preservation channels 102 are combined with the wave structures 101, the heat preservation channels 102 are the same as the wave structures 101 and are both curved. Therefore, the area of the heat preservation channels 102 is increased, so that the human body can obtain more heat.

[0022] Two adjacent wave regions 100 are symmetrically distributed, and two adjacent wave regions 100 form a heat preservation cavity 200 through symmetric weaving. The distance L between two wave crests of the heat preservation cavity 200 is 0.3 cm - 0.8 cm. Preferably, the distance L between two wave crests of the heat preservation cavity 200 is 0.5 cm. The distance H between wave troughs of longitudinally adjacent heat preservation cavities 200 is 0.4 cm - 0.9 cm. Preferably, the distance H between two wave troughs of the heat preservation cavity 200 is 0.6 cm. The area formed by the heat preservation cavity 200 is relatively large. Therefore, compared with the heat preservation channel 102, the heat preservation cavity 200 can store more heat and can provide more heat to the human body.

[0023] Refer to Figure 3, the wavy structure 101 is knitted starting from vertical rows 11 - 13, vertical rows 21 - 23, vertical rows 31 - 33, vertical rows 41 - 43, vertical rows 44 - 46, vertical rows 54 - 56, vertical rows 64 - 66, and vertical rows 74 - 76.

The knitting tracks starting from vertical rows 13, vertical rows 21 - 23, vertical rows 31 - 33, and vertical rows 41 - 43 are all parallel to the knitting track starting from vertical row 11.The knitting trajectories starting from longitudinal rows 44 - 46, longitudinal rows 54 - 56, longitudinal rows 64 - 66, and longitudinal rows 74 - 76 are all symmetrical with the knitting trajectory starting from longitudinal row 11. Therefore, the width of the wavy structure 101 is the width of 3 longitudinal rows. The heat preservation channel 102 is located in the middle of two adjacent wavy structures 101. The heat preservation channel 102 is knitted starting from longitudinal rows 14 - 20, longitudinal rows 24 - 30, longitudinal rows 34 - 40, longitudinal rows 47 - 53, longitudinal rows 57 - 63, and longitudinal rows 67 - 73. The knitting trajectories of the heat preservation channel 102 starting from longitudinal rows 14 - 20, longitudinal rows 24 - 30, and longitudinal rows 34 - 40 are parallel to the knitting trajectory of the wavy structure 101 starting from longitudinal row 11. The knitting trajectories of the heat preservation channel 102 starting from longitudinal rows 47 - 53, longitudinal rows 57 - 63, and longitudinal rows 67 - 73 are symmetrical with the knitting trajectory of the wavy structure 101 starting from longitudinal row 11. Therefore, the width of the heat preservation channel 102 is the width of 7 longitudinal rows. Thus, the width of each wavy structure 101 is one-third of the width of the heat preservation channel 102. And between the two wave peaks of the heat preservation cavity 200, it is knitted as longitudinal rows 35 - 52. Therefore, the width of the heat preservation cavity 200 is the width of 18 longitudinal rows. Consequently, the width of the heat preservation channel 102 is one-third of the distance L between the two wave peaks of the heat preservation cavity 200. The width ratio of the wavy structure 101, the heat preservation channel 102, and the heat preservation cavity 200 is 1:3:6. Reducing the knitting of the wavy structure 101 can reduce the heat loss generated by the human body. The heat preservation channel 102 can provide heat to the human body through circulation, and the heat preservation cavity 200 can store the heat generated by the human body and the heat obtained from the outside, thereby providing heat to the human body in a timely manner.

[0024] In the width direction, the wave peak of the heat preservation cavity 200 in the previous column is opposite to the wave valley of the heat preservation cavity 200 in the next column, and the wave valley of the heat preservation cavity 200 in the previous column is opposite to the wave peak of the heat preservation cavity 200 in the next column, causing the heat preservation cavities 200 to be arranged staggeredly between two columns. The heat preservation cavity 200 can capture more scattered heat instead of concentrating on one place to capture, so that more heat can be stored and more heat can be provided for the human body's needs.

[0025] Refer to Figure 1 , the wavy structure 101, the heat preservation channel 102, and the heat preservation cavity 200 are all knitted into a curved shape, and the curved shape will form a curl for the knitted yarn. Therefore, when the fabric is stretched, the yarn of the curved fabric has better buffering force during the elongation or recovery process, and at the same time improves the structural stability and fatigue resistance of the fabric. Therefore, when the fabric undergoes multiple stretching and recovery processes, the curved shape remains consistent. Combined with the knitting of spandex fiber, the fabric increases its elasticity and will not cause the spandex to break due to excessive stretching, nor will the elasticity disappear due to multiple stretching, so that the stability and elasticity of the fabric can be continuously maintained.

[0026] The fabric is woven with 50D / 12F nylon dull fiber and 70D spandex fiber. The fabric has a warp density of 34 cpc and a weft density of 20 wpi, and is woven into a fabric with a gram weight of 280 g / m². By using one-piece weaving to replace multi-layer fabric lamination, the cumbersome process and lamination cost are reduced. And because the fabric forms a single layer, although the fabric becomes thinner and lighter, its warmth retention performance remains unchanged. Moreover, the use of nylon fiber weaving increases the warmth retention of the warmth channels 102 and the warmth retention cavities 200, making the fabric not heavy and warm after use.

[0027] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
