[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] As Figure 1As shown in Fig. 6, the embodiment discloses a windproof fabric, which comprises a fabric front surface and a fabric back surface. The fabric has 6 courses of loops as one cycle. Each course of loops has 6 upper needles and 6 lower needles as one cycle. The lower needles in the 6 courses of loops are all knitted to form a base cloth area 10 and a cross-shaped area 20. The 1st and 4th lower needles in the 1st course of loops are knitted to loops, and the 2nd, 3rd, 5th and 6th lower needles in the 1st course of loops are floats. The 2nd, 3rd, 5th and 6th lower needles in the 2nd course of loops are knitted to loops, and the 1st and 4th lower needles in the 2nd course of loops are floats. The 2nd and 5th lower needles in the 3rd course of loops are knitted to loops, and the 1st, 3rd, 4th and 6th lower needles in the 3rd course of loops are floats. The 1st, 3rd, 4th and 6th lower needles in the 4th course of loops are knitted to loops, and the 2nd and 5th lower needles in the 4th course of loops are floats. The 1st, 3rd and 6th lower needles in the 5th course of loops are knitted to loops, and the 2nd, 4th and 5th lower needles in the 5th course of loops are knitted to loops. The 2nd, 4th and 5th lower needles in the 6th course of loops are knitted to loops, and the 1st, 3rd and 6th lower needles in the 6th course of loops are floats. Therefore, the base cloth area 10 is formed by the floats of the lower needles in the 1st-6th courses of loops, and the cross-shaped area 20 is formed by the loops of the lower needles in the 1st-6th courses of loops. Since the lower needles in the 6 courses of loops are knitted to the fabric front surface, the fabric front surface comprises the base cloth area 10 and the cross-shaped area 20. Since the cross-shaped area 20 is formed by the loops of the lower needles in the 6 courses of loops, but the 1st and 3rd courses of loops have 2 lower needles knitted to loops, the 2nd and 4th courses of loops have 4 lower needles knitted to loops, and the 5th and 6th courses of loops have 3 lower needles knitted, the 1st-4th courses of loops form a cross-shaped recessed area 202, and the 5th and 6th courses of loops form a cross-shaped protruding area 201. Therefore, the cross-shaped area 20 comprises the cross-shaped protruding area 201 and the cross-shaped recessed area 202. The complex structure of the fabric surface is formed by knitting, so that the direct impact of wind or airflow on the fabric can be reduced, and a physical barrier is formed on the fabric surface, replacing the windproof property of the coating, thereby increasing the windproof property and durability of the fabric.

[0024] Because the several concave areas 202 are located in the 1st-4th coil rows, the several convex areas 201 are located in the 5th-6th coil rows, and after the fabric is knitted, the number of stitches in the 2nd and 4th coil rows is twice the number of stitches in the 1st and 3rd coil rows, and the number of stitches in the 5th and 6th coil rows is balanced, therefore the 1st-4th coil rows are arched upward by the 5th and 6th coil rows due to the stress generated after knitting, and because the average number of stitches in the 1st-4th coil rows is the same as the number of stitches in the 5th and 6th coil rows, the 5th and 6th coil rows are arched in the shape of the outer periphery of the 1st-4th coil rows, thereby being located on the front surface of the fabric, and each of the several concave areas 202 of the several areas 20 is located inside the several convex areas 201, and the several convex areas 201 are higher than the several concave areas 202, and because the 1st-4th coil rows are the several concave areas 202 and the 5th and 6th coil rows are the several convex areas 201, after circular knitting, the several concave areas 202 and the several convex areas 201 are arranged alternately along the length direction of the fabric, and the 1st-6th coil rows all include the base fabric area 10, and the base fabric area 10 is a float, thereby being located on the front surface of the fabric, and along the width direction of the fabric, the base fabric area 10 is located between two adjacent several convex areas 201, and the several convex areas 201 are also higher than the base fabric area 10, therefore the several convex areas 201 are combined with the several concave areas 202 to form a complex fabric surface through the combination of the concave-convex structure and the shape of the several areas, thereby changing the flow direction of the wind, prolonging the path of the wind and the airflow, reducing the wind speed and the direct penetration of the wind, and thereby reducing the heat loss of the fabric.

[0025] 6th loop row, the upper needle is knitted as the back of the fabric, so the back of the fabric includes the base fabric area 10 and the vertical strip raised area 30, because the base fabric area 10 in the 1st-6th loop row is knitted as a float, and the vertical strip raised area 30 is knitted as a loop, so the loop of the vertical strip raised area 30 will press the float of the base fabric area 10, so the base fabric area 10 is lower than the vertical strip raised area 30 on the back of the fabric, because each of the 1st-6th loop row includes the base fabric area 10 and the vertical strip raised area 30, so on the back of the fabric, the vertical strip raised area 30 and the base fabric area 10 are arranged alternately along the width direction of the fabric, and the base fabric area 10 is located between two adjacent vertical strip raised areas 30 along the width direction of the fabric, so when the 1st-6th loop row is knitted to form the fabric, because each loop row knits to form the front of the fabric and the back of the fabric, so the front of the fabric and the back of the fabric are opposite, and because the base fabric area 10 is a float, so the base fabric area 10 on the front of the fabric and the back of the fabric is the same base fabric area 10, so the front of the fabric and the back of the fabric are connected through the base fabric area 10, and the back vertical strip raised area 30 knitted by the 1st-6th loop row corresponds to the front H-shaped area 20, because the lower needle in the 1st-6th loop row is knitted as a loop with an average of 3 stitches, and the upper needle in the 1st-6th loop row is also knitted as a loop with 3 stitches, so the width of the vertical strip raised area 30 is equal to the width of the H-shaped area 20, so when the front and back of the fabric are knitted at the same time, the H-shaped raised area 201 and the vertical strip raised area 30 form the first space 40, and the H-shaped recessed area 202 and the vertical strip raised area 30 form the second space 50, but because the H-shaped raised area 201 is higher than the H-shaped recessed area 202 on the front of the fabric, so on the front of the fabric, the height of the first space 40 formed by the H-shaped raised area 201 and the vertical strip raised area 30 is lower than the second space 50 formed by the H-shaped recessed area 202 and the vertical strip raised area 30, so the existence of the first space 40 and the second space 50 increases the space inside the fabric, and the 6th loop row is knitted by using ultra-fine nylon fiber and spandex fiber, so the internal space formed by the ultra-fine nylon fiber can store static air through the internal space, so that the single-layer fabric formed by high-density knitting can also increase the warmth by using the single-layer fabric, and because the length and height of the first space 40 and the second space 50 are different, so the first space 40 and the second space 50 and the vertical strip raised area 30 form different sizes of internal spaces,The still air in the space can be regulated by storing different amounts of still air in the internal space of different sizes, so that the warmth retention of the fabric is more balanced.
