An encyclopedia of sewing technology for plush toys

Preparation before sewing

(1) Selection of needle and thread

There are No.9, No. 11, No. 14, No. 16 and No. 18. The larger the number, the thicker the needle.

The choice of machine needle is that the thicker the sewing material is, the thicker the needle is; the thinner and softer the cloth is, the finer the needle is. In principle, the selection of stitches is the same. Needle type 911141618 use thin silk, medium thick cotton, heavy denim and tweed

(2) Stitch and stitch pitch scheduling

Clear and regular stitch and suitable stitch pitch density are important aspects to measure sewing quality. The stitch scheduling is controlled by the scheduling equipment. It is necessary to rotate the stitch length to the left and the stitch short (dense) to the right. It is also necessary to reasonably arrange the stitch according to the thickness, tightness and hardness of the material. When sewing thin, loose and soft fabrics, the bottom line should be properly relaxed. The presser foot pressure feed teeth should also be properly lowered, so that the phenomenon of Zou shrinkage can be avoided when sewing. The plush toys are customized with the surface fabric of the manufacturer. In order to make the stitches clear, the upper thread can be slightly relaxed. When the edge is rolled up, the bottom line can be slightly relaxed due to anti seizing.

Before sewing, it is necessary for the manufacturer of plush toys to adjust the needle pitch. Sewing needle spacing should be appropriate, too thin needle spacing is not beautiful, and affect fastness. Too close needle spacing is not good-looking, and vulnerable clothing materials. In general, the length of 3cm of thin and worsted fabrics is 14-18 stitches, and that of thick fabrics and woollen fabrics is 8-12 stitches.

Sewing operation

The first sewing equipment for plush toys is electric sewing machine. The first tools are tweezers, scissors, soft ruler and ruler.

Before sewing, you should master some basic knowledge

Needle distance: when sewing, the distance between the two needles is the needle distance. Generally, the distance of plush material is about 4-5 stitches per 1cm, (about 10-12 stitches / 1 "), and 5-6 stitches (about 12-13 stitches / 1") at 1cm distance of flannel cloth, t / C cloth and satin cloth.

Stop: the distance between stitches and blades. Plush toys often have a 5 mm stop. Suppose that the standard of sample plate or product is large, and most of the seam is 6 mm. If the sample plate or product is too large, the mouth joint is 3 / 8 "- 1 / 2". Such as tents (Oxford or canvas material texture). Generally, 1 / 8 "is used for small sample or product stop, such as 3" H wool cutting bear.

Back stitch: in a certain part, add two or more stitches back and forth in a short distance. It is usually used at the head and tail of the splicing material to prevent the loose line or reinforce a certain part, such as the clip ear, tail, trademark, etc., which need to be reinforced by back stitching.

Stitch: the track of stitches left after sewing.

Feed wool: generally only plush products. When stitching, use tweezers or other things to induce the plush along the edge of the cut piece, and scrape it between the two pieces of the opposite piece, which is called hair.

Discount: that is to say, the sutured pieces are folded.

Crinkling: when sewing, the edge of the cutting piece is evenly wrinkled.

Pleat: the folded part does not need to be sewn, and the wider obvious fold is called fold.

Thread throwing and needle skipping: when a piece of suture is cut, one side of the bottom line and the other side of the upper thread are loose and the other side is tight, so that the floating line can be drawn out on one side. If there is a hook on the thread trace, the phenomenon that the needle pitch is more than twice the normal needle distance is called skipping stitch.

Stitching: also known as pointing, it is the most fundamental sewing method in sewing. The two pieces (generally) are overlapped on the front side and sewed according to the regular seam stop. In the actual operation process, because the bottom cutting piece has the feeding teeth to push directly forward, while the upper cutting piece moves forward slowly due to the friction of the presser foot, so it is necessary to select appropriate gesture or clamp the upper and lower layers of cutting pieces with tweezers to feed forward the sewing together, so as to avoid the dislocation of the upper and lower layers of the cutting pieces during sewing.

Thread editing: also known as embossing thread, which is to collect the thread on the surface of toy or doll's shirt parts or parts, so as to reveal the thread trace as decoration. Such as: editing pocket, editing stitching, editing picture, etc.

Curling: fold the edge of sheet material directly to internal force, and then open line. There are two kinds of curling: single layer and double layer. The single layer is to fold the edge of sheet material inward once, and then edit the line. Double layer means that the edge of fabric is folded inward continuously for two times, and the edge rolled out by crimping presser foot is double-layer.

Hemming: a piece of cloth with a 45 degree oblique angle (the width of the cloth strip is various, but it should be the same as the binding edge) is passed through the edging (there are different standards) and the raw edge of the sheet is covered with light as a sewing process for decoration.

Bone position: two or more pieces of material after the seam to form a seam trajectory, called bone position.

1. In the case of no special requirements for garment stitching, it is generally necessary to adhere to the upper and lower seams together when sewing. The upper and lower garment pieces are pushed directly by the cloth feed, and the upper layer is resisted by the presser foot and the cloth feed is pushed slowly. The upper layer is often long and the bottom layer is short, or the sewing seam is loose and shrunk. Therefore, the corresponding operation method should be adopted according to the characteristics of machine sewing. Pay attention to the hand gestures during the initial sewing. Push the garment piece forward with the left hand, and tighten the bottom layer with the right hand. If the sewing position is too small, it is not suitable to tighten it by hand. The tightness can be controlled by driller or fitter. Only in this way can the upper and lower garment pieces always adhere to the tightness together, and can not be connected. This is the most fundamental method of operation.

2. Machine stitched Dacron up and down needles can be cut down as needed

Generally, machine sewn broken wires can be stacked, but the reverse needle can not present double track.

3. All kinds of machine stitching should be fully sewn with no false stitches.

4. Pay attention to the tightness of the upper and lower layers in the crimping seams, pressure taps and all kinds of overlying seams. Assuming that the upper and lower layers are dislocated, they will form a twill ripple.
