Number Description
Chain stitch: A stitch formed by one or more needles and threads connecting themselves. Its characteristic is that after a loop of a suture thread passes through the sewing material, it connects with the same or several loops in sequence. Hand stitch: A stitch originated from hand sewing. Its characteristic is that a suture thread passes through the sewing material and consolidates the sewing material. Lock stitch: A stitch formed by a group of (one or several) suture thread loops, which pass through the sewing material and interweave with another group of suture threads (one or several).
Multi-thread chain stitch: A stitch in which the loops of a group (one or more) of sutures are inserted into the sewing material and then interconnected with the loops of another group (or more) of sutures.
Overlock chain stitch: A stitch formed by a group (one or more) of sutures in a self-connected or interconnected manner, with the loops of at least one group of sutures wrapping around the edge of the sewing material, and the loops of a group of sutures are inserted into the sewing material and then interconnected with the loops of one or more groups of sutures.
Cover chain stitch: A stitch in which two or more groups of sutures are interconnected, and two of the groups of sutures cover the upper and lower parts of the sewing material. After the loops of the first group of sutures are inserted into the loops of the third group of sutures fixed on the surface of the sewing material, they are then inserted into the sewing material and interconnected with the loops of the second group of sutures on the bottom surface of the sewing material. However, the 601 stitch is an exception, which only uses two groups of sutures. The function of the third group of sutures is completed by one of the first group of sutures. 4.1 Stitch number: Each type of stitch is represented by the first digit of the three-digit number. The stitch pattern in each type of stitch is represented by the second and third digits.
4.2 Combined stitch number: The combined stitch number is represented by the number of each stitch pattern, separated by a dot "," in the middle, for example 401502.
If the combined stitch pattern is formed in one operation, its number is marked in brackets, for example: (401·502). New generation authorized search area

Graphic drawing method
GB4515--84
In the stitch pattern diagram (see Chapter 6), the following principles are used for drawing. 5.1 In order to make the diagram clear and easy to identify, the perspective method is used to select the best angle that can clearly show the stitches. 5.2 The direction of the continuous stitch pattern is from right to left. 5.3 The beginning and end of the stitch are indicated by the ends of the thread only, and the needle thread leaves the sewing material in a vertical direction. 5.4 All stitches are indicated by outlines only, while other threads are indicated by slashes. 5.5 All stitches are indicated by numbers 1, 2, 3, all shuttle threads are indicated by letters a, b, c, and all covering threads are indicated by ZY, X, **.
5.6 The material shall be shown only when it helps to make the sub-stitch pattern clear, as shown in Class 500. Note: In some cases, when the above-mentioned depiction method does not enable the stitch pattern to be clearly shown, a flat diagram is used. 6 Diagrams

This stitch type is formed by two needle threads (1 and 2). The loops of thread 1 and thread 2 pass through the sewing material from one side of the machine needle. On the other side of the sewing material, the loop of thread 2 connects with its own previous loop and then connects with the loop of thread 1. At least two stitches are required to describe this stitch type. 103
This stitch type is formed by a needle thread (1). Its loops pass through the sewing material from one side of the machine needle, and the part that passes through the sewing material is still exposed on the needle surface, and reaches the next needle puncture point to connect with each other. At least two stitches are required to describe this stitch type. 104
This stitch type is formed by a needle thread (1). Its thread loop penetrates the sewing material from one side of the needle, then passes a certain distance, returns to the needle side, and connects itself at the next needle piercing point. At least two stitches are used to describe this stitch type. GB 4515-84
This stitch type is formed by a needle thread (1). Its thread loop penetrates the sewing material from the needle side, passes through the ...-part of the sewing material, and then emerges on the needle side, and connects itself at the next needle piercing point located on the axis of the stitch formation. At least two stitches are used to describe this stitch type. 107
This stitch type is formed by a needle thread (1). Its thread loop penetrates the sewing material from the needle side, and connects itself on the other side.

Sewing material surface
This stitch pattern is formed by two needle threads (1 and 2). They pass through the same puncture hole of the sewing material from opposite directions, and then the two threads go forward an appropriate length and pass through another puncture hole of the sewing material from opposite directions. The two threads do not interweave or interconnect. At least two stitches are required to describe this stitch pattern. 202
This stitch pattern is formed by a needle thread (1). After the thread passes through the sewing material, it passes back through the sewing material to an appropriate length, then pulls out 1/2 of the forward length backward and passes through the sewing material again. This stitch pattern is often used to form the start and end of other stitches. At least two stitches should be used to describe this stitch pattern. 204
This stitch pattern is formed by a needle thread (1). After the thread passes through the sewing material, it pulls out an appropriate length backward, passes back through the sewing material, moves diagonally a distance equivalent to the width of the stitch, passes through the sewing material again, pulls out the same length as the previous time backward, passes back through the sewing material again, and then moves diagonally a distance equivalent to the width of the stitch. This process is repeated, forming separate parallel rows of stitches on one side of the machine needle, and a cross-shaped pattern on the other side of the sewing material (for example, when sewing by hand, this stitch pattern is generally sewn from left to right). At least two stitches should be used to describe this stitch pattern. 8
GB4515--84
This stitch pattern is formed by a needle thread (1). After the thread passes through the sewing material, it is pulled forward to an appropriate length, then returns to pass through the sewing material, pulled backward to 1/3 of the length pulled forward, and passes through the sewing material again. At least two stitches are used to describe this stitch pattern. 206
This stitch pattern is formed by a needle thread (1). After the thread passes through the sewing material, the continuous stitch formation direction is pulled out to an appropriate distance in a direction perpendicular to the sewing material, then returns to pass through the sewing material and passes under the line of the previous stitch. The continuous stitches are arranged at selected intervals and can be sewn to have larger or closer intervals (for example, when sewing by hand, this stitch is generally sewn from left to right). At least two stitches are used to describe this stitch pattern. 209
This stitch pattern is formed by a needle thread (1). The thread passes through the sewing material, pulled forward to an appropriate length, and returns to pass through the sewing material. The distance between the needle piercing points can be very close, so that the sewing material can be assembled into broken wrinkles, or wrinkles of measured size can be sewn. The distance between the needle piercing points can also be larger, or piercing points with different spacings can be arranged alternately. At least two stitches are used to describe this stitch type.

This stitch type is formed by a needle thread (1). After the thread passes through the sewing material, it wraps around the edge and then passes through the sewing material, and is straight with the exposed point of the front thread.
This stitch type is generally used on soft and thin sewing materials and can be applied to the sewing of the sewing material edge. This stitch type can be arranged with different spacings. At least two stitches are used to describe this stitch type. 213
This stitch type is formed by a needle thread (1). The thread passes through the single-layer sewing material part, and then passes through the ... part of the seam material curling edge (the seam material edge is curled up), and the seam thread is slightly exposed on the other side. The front piercing point of the tooth is in a straight line, and a very small amount of sewing material is tightened, and then the seam thread is pulled forward and repeatedly passes through the single-layer sewing material under the curling edge. This stitch pattern is used when the stitch is required to be invisible on the other side of the sewing material or to be slightly exposed. At least two stitches are used to describe this stitch pattern. 214
This stitch pattern is formed by a needle thread (1). It passes through the sewing material stack and enters the single-layer sewing material at a known distance slightly to the right and above, and then the remaining seam thread passes through the double-layer sewing material obliquely to reach a straight line with the front seam thread exposure point. This stitch is used to sew one sewing material to another sewing material, such as sewing the lining of clothing. At least two stitches are used to describe this stitch pattern. 10
GB451584
This stitch pattern is formed by a needle thread (1). It passes through the folded edge of the sewing material, is pulled forward to an appropriate length in the layer, and then is passed back through the material, then slightly backward through the opposite folded edge of the sewing material, is pulled forward to an appropriate length, and is passed back through the sewing material to tighten the seam thread.
This stitch pattern is generally used to sew two folded edges together. For example, a collar and a lapel. This stitch pattern is rarely drawn with two stitches. 217
This stitch pattern is formed by a needle thread (1). It passes through the sewing material layer obliquely, is pulled out to an appropriate length behind the point where the seam thread is exposed, and then is passed forward through the sewing material to form an intersection with the first residual thread. This stitch pattern only has a small mark on the surface of the sewing material, and this stitch pattern is rarely drawn with two stitches. 219
Generally used in sewing the edges of garments.
This stitch pattern is formed by a series of needle threads (1). The thread passes horizontally through the material or part of the material. The thread segments exposed above the material are all at acute angles to the successive needle penetration points. The successive needle penetration points are parallel to the stitch formation area and form a straight line.
The alternating rows of stitches are formed in opposite directions and are staggered. This stitch pattern is used in the process of sewing collars and lapels with lining. This stitch pattern can also be used to sew lining as lining, and the lining thread often passes through both materials. At least two stitches are used to describe this stitch pattern. 11

This stitch pattern is formed by a needle thread (1). The thread is passed through the material close to the edge of the buttonhole cut, then moved vertically to the edge of the cut hole on the back of the material, passed through the loop of the previous stitch, tightened, and passed through the material again to form a knot on the cut edge. This stitch is used to lock the cut edge of the buttonhole. When used as a buttonhole, the thread can be inserted from the left or right, from the bottom or from the top, and a narrow braid can be re-sewn to give a stronger effect. At least two stitches are used to describe this stitch pattern. 300
