The selected stitching should match the sewn piece

1. The selected sewing machine should match the sewn piece
The thread used for sewing clothes is collectively referred to as sewing thread. The thread used to sew woolen sweaters should have the same color as the desired piece of clothing. Otherwise, when the stitching is exposed on the surface of the sweater, it will affect the appearance. Regarding jacquard products and color blocking products, the color with a larger proportion of colors at the stitching is generally chosen as the stitching color. For individual woolen sweaters that use stitching as decoration, the stitching color can be selected according to their needs. The thickness of the suture also has a significant impact on the quality of stitching. It should be determined based on the thickness of the fabric yarn, the selected sewing equipment, method, and stitch density. When it is too thick, stitching is difficult, and when it is too thin, the appearance and fastness are affected. In general, in order to sew smoothly, it is better to have a thinner or the same thickness of suture than the fabric yarn. In order to ensure consistency in functionality and color between the garment pieces and stitching during prolonged wearing, it is required that the stitching material be the same or similar to the garment piece material. Other stitches should have high strength and uniform strength, with a smooth and even appearance, moderate and even twist, soft and elastic. The stitching should be tightly wound, lubricated without burrs, knots, and scratches to reduce breakage and broken needles.
2. The stitching should be flat and able to express the style characteristics
Stitch refers to a seam formed by connecting threads. Due to the high extensibility, elasticity, and certain degree of detachment of woolen sweater pieces, it is necessary for the selected stitching to have extensibility and elasticity that is suitable for the sewn piece and its location, and to prevent the detachment of the edge coils of the piece. When sewing, the pieces of clothing should be accurately aligned according to the markings. The seam should be flat and the stitching should not attract attention. When using machine sewing, the looseness of the upper and lower threads should be moderate to prevent wrinkles and minimize deformation of the garment pieces. The stitch density should be greater than or equal to the density of the sewn piece, and the density should be uniform without needle holes. When the end of the seam needs to be reinforced, it should be turned back for reinforcement, and the thread should be hooked into the garment piece to make the surface neat without any thread. In addition to relying on the shape of the garment, it is also necessary to rely on the matching stitching to express the style and shape of woolen sweaters. This requires the stitching direction to be correct, the transition should be smooth and smooth, and the elasticity should meet the styling requirements and reflect the planning purpose.
3. Stitching should have sufficient firmness
The so-called stitching fastness refers to the service life of a woolen sweater that is not damaged by repeated stretching and conflicts during the wearing process. The stitch fastness is influenced by the stitch structure and elasticity of the stitching, especially in areas that are often stretched during the wearing process. It is necessary to use elastic stitch structures and stitching to ensure that the stitching is not pulled off and the seam will not come loose during use. The strength of the stitching is directly related to the strength of the stitching. The greater the strength of the selected stitching, the greater the strength of the resulting stitching. Generally, when the stitch density is high, its strength is also high, but when the stitch density is too high, the strength decreases and the thread consumption increases. The wear resistance of the stitching also has a significant impact on the fastness of the stitching. When wearing a sweater, almost all stitching is subject to conflict, especially in areas with high tensile strength. Conflicts between fabrics and stitching, as well as between the human body or underwear and stitching, occur more frequently. Practice has proven that most damage to stitching is caused by grinding and breaking the stitching, so the stitching must be wear-resistant.
Standard selection of sleeve car:
The opening is carried out on a woolen sweater sewing machine, and the machine number of the sewing machine should match the machine number of the woolen sweater weaving machine. When selecting the machine number of the sewing machine, please refer to the table below. When stitching woolen sweaters, the horizontal sleeve wear is 2-3 rows, and the vertical sleeve wear is 1-2 stitches. When sewing woolen sweaters, a piece of 28x2tex~31x2tex worsted yarn of the same color is commonly used as the sewing thread; When sewing synthetic fiber products, raw materials are commonly used as sewing threads. It is not allowed to have needle lines tilted or overlapping during opening. This is used for shoulder closure and sleeve fitting. The elongation of shoulder seams should be greater than 110%, and the elongation of hanging shoulder seams should be greater than 130%.
