A seam is a sewing thread that stitches two or more textiles together. They can be any material, such as fabric or leather, to hold them together with stitching. It is an essential part of a swimsuit. Seam line means a seam line parallel to the seam. Industrial sewing machines sew seams on modern mass-produced outdoor goods, home textiles, footwear and swimwear. Knitting, tailoring, home shoemaking, etc., using a mixture of machine and hand sewing.

If you are new to the swimsuit business and have recently had a swimsuit purchase assignment, you should have a good understanding of seams. In clothing manufacture, there are different classifications of stitching, and the same is true for swimwear manufacture.

What is hemming?

The swimsuit maker sewed it with a rope hem. The thick seam is first performed on the opposite side and then on the right side.

What is a thimble seam?

Topstitch is a row of stitches on a swimsuit top that improves its appearance while providing a finish to its burrs.

What is the safest seam?

The strongest seams are "flat seams" that have hidden burrs and do not come apart. They have a neat finish. Therefore, manufacturers use it on both thick and thin fabrics.

Fabric type

Swimsuit fabrics can be very fussy. It comes down to several characteristics such as stretch quality, recovery, transparency and fiber content. The fabric should be a mixture of spandex, lycra or spandex, about 10 to 20 percent, with the rest made of nylon or polyester. Excellent recovery after stretching.

Nylon blended

One of the most common swimsuit fabrics is nylon blends. Nylon is a synthetic fiber. Nylon blends are mixtures of nylon fibers and spandex fibers, such as Lycra, that are blended together to form this durable stretch fabric. This is a popular choice for swimwear because of its soft feel and shiny surface. The disadvantage of nylon mixtures is that they are not the best in chlorine resistance and uv linearity.

Polyester blended

Polyester blends are some of the strongest and most durable swimsuit fabrics. Polyester, like nylon, is a synthetic fiber. Polyester blends are mixtures of polyester fibers and spandex fibers (such as lycra) mixed together to form polyester blends. Polyester blends are a very popular choice for swimwear fabrics because of their durability. In addition to durability, polyester blends are uv and chlorine resistant.

knitting

Tricot is a run-proof knitted fabric that is light and smooth but durable enough to fit in underwear, swimwear or sportswear. Warp knitting is a knitted fabric because of fiber structure rather than fiber content. You can find warp knitted fabrics in nylon blends and polyester blends.

Neoprene/scuba knitting

Neoprene, also known as Scuba kinit, is a common fabric used in diving suits for water sports activities such as diving and surfing. Neoprene is a dense fabric made from rubber, but is lightweight and can be comfortably worn underwater

Lycra and spandex

The two fabrics are one and the same. The difference lies in the name. Lycra is duPont's spandex brand. Spandex is a general-purpose synthetic fiber that gives swimwear stretch properties when mixed with other fibers

Stitch type/length

You might think you have to have a sergeant when sewing swimsuits, but the basic zigzag stitch is actually swimsuit sewing's best friend. Depending on which part of the suit you sew (elastic vs. seam), you will need to vary the width and length of the zigzag. Do some experimentation on scrap to find the stitch that best suits you and your fabric.

strapping

Many swimsuits have many straps, most of which are supported by elastic bands. There are different ways to make these watch straps.

Stitch quality measurement

While functional or aesthetic requirements determine the type of stitch, you can measure the quality of the seam based on the factors listed below:

The joint strength

It is the force necessary to tear a suture, either by destroying the suture material or the thread.

Joint slip strength

Pulling out a certain amount of opposite strands perpendicular to the seam line is a necessary effort.

Joint size

It helps determine the width, length and depth of the joint.

Joint common goal,Hidden edges, seams divided into two parts. One is fancy, the other is functional.

Decorative, decorative seams outline the swimsuit and give it a visual appearance. Channel seams, which create an open network over a contrasting piece of cloth as the user moves, revealing a flash of pattern or color.

Vienna seams, which are similar in appearance to princess seams. It is a curved seam that attaches to the front of the swimsuit to emphasize the curves of the body. However, unlike princess sewing, it starts at the armhole rather than the shoulder.

Flax seam, which uses embroidery or decorative stitches to join two pieces of cloth together at the edge. It's not particularly powerful, but it's attractive.

Hong Kong sewing, it is a finishing technology, commonly known as Hong Kong finishing. You can bind or hem seams with seam tape to give them a Hong Kong look. A contrasting color or patterned seam tape inside a swimsuit can provide an elegant touch. Unlined clothes and jackets are the most common uses of this technology. Consult swimsuit factory.

Princess seaming, it is one of the decorative seams that can handle a lot of work. Women's princesses sew the most. They don't need darts because they shape the body of the garment into a curved waist line.

Swimsuit creation

Most swimsuits already have seams in fabric pieces.

Inner seams, which join the inside parts of the leg. Front and back seams, they join the left and right parts of the garment. Side seams, they connect the front and back of the garment. Shoulder slits, they tie the cloth shoulders together.
