The industrial blind sewing machine (also known as seaming machine, copying machine) is used for the seaming of various fabrics. Because most fabrics are cut off after the edges are cut off, they need to be seamed before they are finished to prevent the fabric from dissipating.
The industrial blind stitch sewing machines is most suitable for knitted fabrics. Because they are mainly cotton, polyester and polyester yarn. This fabric is characterized by soft texture, high flexibility, breathability, sweat absorption, comfortable wearing and personality. Knitted fabrics also have other characteristics such as dispersibility, curling, easy pilling, etc. Therefore, special processes are required in the sewing production process of garments, so the industrial blind sewing machine and the stretch sewing machine are inseparable.
The blind is the sewing of the edges of the fabric. Since the knitted fabric is composed of a coil string sleeve, the edge of the cut garment piece is prone to disintegration, so the edge of the garment sheet should be overwrapped (commonly referred to as "copying edge") and then sewn by a sewing machine or the like. The sewing machine and blind sewing machine are the main types of sewing knitwear.
And there are some simple sewing machine in the market.But what are the differences between these two kind of sewing machines?
The common sewing machine is generally used for the upper and lower stitching of the fabric. This kind of machine uses straight lines. Today's multi-function sewing machines have many decorative stitches. If it fitted with a locking presser foot, a simple seaming function can be achieved with a "Zigzag" type of stitch.
(Professional explanation: The sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or stitch one or more layers of sewing material. The sewing machine can sew cotton and hemp. Fabrics such as silk, wool, paper and so on. The stitches are neat and beautiful, flat and firm, and the sewing speed is fast and easy to use.)
An blind stitch is a stitch that is looped over a number of stitches at the edge of the seam. The name is called according to the number of stitches that make up the stitch (single-line blind, double-strand blind... six-slit blind). It is characterized in that the edge of the sewing material is wrapped to prevent the edge of the fabric from being dissipated. When the stitch is stretched, the upper thread and the bottom thread can be transferred to each other to a certain extent, so that the seam has good elasticity.
Some blind stitch sewing machines have the function of a seam. There is also a separate stretch sewing machine.
The seams are mainly used in the cuffs and hem of a knitwear (a few neckline). The front side is a double-needle or three-needle straight seam, and the reverse side is a zigzag chain stitch. Stretch stitches are characterized by strong strength, good stretchability, and smooth stitching, which can prevent the edges of the fabric from dissipating. Stretch seams are often used for piping, roll collars, hem, seam stitching, and trims, which provide high strength and elasticity and smooth stitching.
In a general sense, a sewing machine is a machine that joins two pieces of cloth together, and a sewing machine is a machine that makes the edge of a piece of cloth firmer.
