Sewing, used to refer to the textile, sewing, and embroidery work performed by a woman. Today's sewing workers mainly refer to garment production workers. People are more accustomed to using the term "women" to refer to women workers engaged in textile, sewing, embroidery, etc.

From sericulture and cotton growing to spinning and weaving, from needle threading to sewing and dressing, it is a great progress of human civilization. In the history of the Chinese civilization of 5,000 years, textiles and clothing are two beautiful and dazzling wonders. Therefore, the history of female red work, which is closely related to it, should be very long. According to archeological finds, in the Paleolithic age 18 thousand years ago, cavemen have used bone needles to sew animal skins;

This profession is divided into 7 levels: second-level sewing, third-level sewing, fourth-level sewing, fifth-level sewing, sixth-level sewing, seventh-level sewing, and eight-level sewing.

Thread fraying

During the sewing process, due to the high speed of the thread passing through the thread passing part, the thread of the thread passing part is not smooth and the part of the fiber of the thread is worn away, which causes the suture fiber to be loose and the surface of the suture to show independent fiber fluff. phenomenon.

Staggering stitch

When sewing straight, the stitches are not parallel to the feeding direction. When twist sewing, one stitch is not parallel to the same stitch. This is called skew.

Skip stitch

During sewing, because the hooking mechanism cannot catch the loop of the needle thread, a complete continuous stitch cannot be formed in the seam. The discontinuous stitch is called skip stitch.

Wrinkled pumpers

After the sewing material is sewn, the shrinkage of the sewing material in the feeding direction is called wrinkling. The shrinkage of the sewing material perpendicular to the feeding direction is called transverse wrinkling.

Twist twist

When sewing, the tension of the suture is too large, which causes the sewing material to curl and uneven.

Erraic stitch pattern

After the pattern of the embroidery machine is sewn, due to the failure of the machine's controller or machinery, the phenomenon that the pattern after sewing does not match the set pattern shape.

Needle bar mechanisms

When the sewing machine is sewing, the needle bar with a motive needle and a guillotine thread pierce the sewing material to sew.

Fixed needle bar mechanism: the needle bar only reciprocates up and down in the needle bar hole of the machine head, and the mechanism is a mechanism in which a needle with a motive needle and a piercing thread pierce the sewing material for sewing.

Swinging needle bar mechanism: The needle bar reciprocates up and down in the needle bar hole of the swinging frame connected to the machine head with a piercing thread to pierce the sewing material for sewing. Swing modes include linear swing from left to right or front to back, and arc swing around the fulcrum.

Presser

A member that applies pressure on the surface of the sewing material. Presser foot is divided into lockstitch presser foot, overlock presser foot and special machine presser foot according to its sewing machine performance. Presser foot is divided into ordinary presser foot and special presser foot according to its function. There are many types of special presser feet, such as crimping foot, feeding foot, double needle foot, etc.

Press bar mechanisms

A mechanism for applying pressure on the surface of the sewing material. It is classified as:

Compression lever mechanism: There is a mechanism that the presser foot applies pressure on the surface of the sewing material.

Alternating pressing rod mechanism: a mechanism with two pressing feet alternately pressing on the surface of the sewing material. One is a non-moving presser foot, and the other is a presser foot that moves with the sewing material or the needle.

Roller pressing mechanism: a pressing mechanism with one or two rollers to apply pressure on the surface of the sewing material.

Press bar lifting mechanisms

Mechanism for lifting and releasing the presser foot pressure on the sewing material. The classifications are:

Hand-held mechanism: a mechanism that lifts and releases the pressure of the presser foot by moving the presser foot with the hand plate.

Knee lifter mechanism: A mechanism operated by the knees to lift and release the presser foot pressure through the lever system.

Foot-lifting presser foot mechanism: Operate with a foot pedal to lift and release the presser foot pressure mechanism through the lever system.

Electric, pneumatic or hydraulic presser foot lifting mechanism: a mechanism for lifting and releasing the presser foot pressure by electromagnetic force, pneumatic pressure or hydraulic pressure.

Automatic presser foot lifting mechanism: After sewing, the presser foot automatically lifts the presser foot according to the control sequence.

In addition to the above terms, there are many professional terms.

1.Complete the work of specifying the sewing process. Under the guidance of the order follower, understand the process requirements for the production of style clothing. Specific operating procedures, under the guidance of the workshop director, complete the sewing of the specified process according to the specified quality standards for timely delivery. To the next process.

2. Responsible for the rework of non-conforming products, and rework in time according to the specified quality standards for work in process that is found to have quality problems.

3. Responsible for the routine maintenance of the machine and work station hygiene. At the end of each day, clean the machine table with a clean cloth according to the operating procedures. Use tweezers and clean cloth to remove cloth scraps, thread ends and other debris from the fuel tank, cloth feed teeth, etc. And turn off the power switch at the end of the work.

4. Complete some manual sewing work. According to the arrangement of the workshop director, according to the process and operation requirements, complete the manual sewing of the jewelry.
