Knitted Sweater Sewing Process Knowledge

　　 Cardigan The stitching process should be determined according to its suture requirements and the suture equipment.

Stitching requirements are related to factors such as raw materials, organization structure, density of clothing, styling and color of clothing, and different parts. Therefore, the stitching process is longer and more equipment is used. For example, the technological process of V collar men's cardigan usually is: collar, hot collar, cut, flat seam, chain stitch, hand stitch, semi-finished product inspection, knit, cut, flat seam, blanking, stroke, lock buttonhole, button, remove impurities, ironing, nail brand, product inspection, packaging. Next, according to this technological sequence, the requirements of each process are explained.

1. Socket

The sleeve should be carried on the woollen sweater sewing machine. The machine number of the stitching machine should match with the machine number of the sweater knitting machine. Reference can be made to the following table when selecting the machine number of the sewing machine. The transverse consumption of the sleeves is 2~3 horizontal, and the longitudinal consumption is 1~2 needles. When sewing woolen sweaters, a 28 * 2tex 31 * 2tex worsted woolen yarn is used as a suture. When sewing chemical fiber products, the raw material is often used as suture. It is not allowed to have the needle pattern deviation and the needle insertion. It is used for shoulder and sleeves. The elongation of shoulder seam should be more than 110%. The elongation of the seam should be more than 130%.

The suture line of pure wool products is colored with 17x3 (Tex) cotton yarn or 16x3 polyester (Tex) polyester thread, and the bottom line is the 28x2 (Tex) wool yarn with the same color as the shirt body. When the chemical fiber products are stitched, the general line is the same as that of the pure wool products, and the bottom line is used for the raw material of the garment. The stitch density of flat stitches is 11~14 needles per 2.54 cm. It is used to sew collar and plaid, the neckline curl edge from the front right collar, along the back shoulder seam to the left collar, the collar stitch is placed in the third needle, the front flap is placed on the front face of the front garment, aligned to the hem, the V neckline and the back collar powder line, and from the right lower lip to the left side of the lower lip.

The chain seam is carried out on the trimming sewing machine. The seam consumption is 0.5 to 0.7 cm, 3~4 pin for fine needle product, 2~3 pin for thick needle product. When sewing sup products, a 28x2 tex (31x2) (Tex) worsted wool yarn that is the same color as the shirt is used as suture. When sewing chemical fiber products, the raw material is often used as suture. If it is used to stitch round collar men's pullover, the neckline should be pulled up to 32 centimeters. The stitched round neck Pullover should be 30 centimeters, and the collar collar should be stitched up to 28 centimeters. The stitching density of chain stitches is generally /11 ~ 12 needles per 2.54 cm, and the elongation of suture should be greater than 130O%. It is used to fit the seam and sleeve bottom seams. It should be reinforced and returned to two centimetres at the beginning and end.

Six. Hand sewing

Hand sewing refers to manual stitching. This suture is flexible, with large seam changes, which can sew different parts of the request, but the efficiency is low. Here is used to complete some of the following work, sewing the bottom ribs, sleeves daily ribs, sewing the bottom of the bag according to the technological requirements, sewing the bag belt first to open the bag clip yarn, evenly sewing the ends from the bag end to the other end, the two ends are the same height; according to the width and width of the width of the door, the ends of the seam can be flush with the rib, and the reinforcement between the swing joints and the sleeve bottom seams should be strengthened.

Seven, semi-finished products inspection

It mainly checks suture defects, so as to timely repair, prevent defects from leaking into the next process.

Eight. Shrinkage

Chemical fiber products do not need this process. Wool products should be processed according to the process of fulling, and dehydration and drying should be done after milling.

Nine. Tailoring

Cut the front part of the needle, cut the ribbon (the length of the ribbon = the length of the garment is &nbsp3 cm, the ribbon is retracted) and draw the line according to the regulations. Pullover products do not need this procedure.

Ten. Flat seam

Eleven, ironing

Iron flat door, easy to scribe line, lock button hole.

Twelve. Lock the buttonhole.

The number of button holes is drawn on the reverse side of the left side of the flap, and the first point of the powder line is drawn at the depth gauge. The lowest hole is drawn in the middle of the bottom rib, and the middle line is evenly divided into a powder line. The use of button hole machine lockstitch and buttonhole, stitch density with ribbons for each cm about 17 needles, 12 needles without ribbon. Button hole size should be adjusted as required.
