How to choose a sewing machine to sew different fabrics?

Nonwoven fabrics are widely used in disposable sewing products such as packaging bags and medical materials. as the non-woven fabric has poor elasticity (elasticity), the lock stitch sewing machine with small elasticity (elasticity) of sewing stitch is generally selected, that is, the common lockstitch sewing machine.

Due to the structural characteristics of the fiber fabric, there are gaps of different sizes in the fabric fibers. When the needle is punctured, the resistance of the fiber fabric is relatively small. Therefore, the stitchability is good. Generally, a sewing machine with a high sewing speed can be selected. for example, the lockstitch sewing machine can select a variety with a sewing speed of more than 5000 R / min, and the overlock sewing machine can select a variety with a sewing speed of more than 6000 R / min.

Leather sewing materials are also common sewing materials. leather materials are generally divided into leather and artificial leather. Leather is a kind of leather material made of animal skin, which is a natural leather sewing material.

·Leather sewing material 

·Leather sewing materials are widely used in clothing, shoes and hats, bags, canopies and sails, home decoration, automobile decoration, and other sewing industries. since leather fabrics have almost no elasticity (elasticity), lock stitch sewing machines with small elasticity (elasticity) of sewing stitches are generally selected, that is, common lockstitch sewing machines.

·Artificial leather sewing material 

·Leather materials made of chemical materials or mixed with fiber fabric materials are artificial leather sewing materials. synthetic leather sewing materials are widely used in clothing, shoes, hats, bags, canopies, and sails, home decoration, automobile decoration and other sewing industries. as the stretch (elasticity) of artificial leather fabric is very small, the lock stitch sewing machine with small stretch (elasticity) of sewing thread is generally selected, that is, the common lockstitch sewing machine.

Since the structure of the leather fabric is relatively tight and there is basically no gap, the puncture resistance of the leather is relatively large when the needle is punctured, so the stitchability of the leather fabric is not as good as that of the fiber fabric.generally, the sewing speed of the sewing machine is below 3500r / min, and the feeding mechanism of the sewing machine has special requirements. not only the function of lower feeding but also the function of upper and lower feeding; Upper and lower differential feeding function.
