How to make a seamless bra with dot glue machine?

Seamless bras are popular among consumers for their comfort, seamless feel and streamlined design. With the continuous advancement of technology, more and more manufacturers are beginning to use dispensing machines to make seamless bras. Dispensing machines can effectively achieve seamless fitting design of bras through precise glue coating technology. This article will detail how dot glue machines work, how to apply them in seamless bra production, and the advantages brought by this technology.

1. Basic principles of dot glue machines

A dot glue machine is a device that accurately releases glue through an automated control system. It can control the flow, speed, time and position of the glue to achieve high-precision glue coating. Common types of dispensing machines include pneumatic, servo motor controlled and precision controlled. Depending on the application, dispensing machines can be applied to a variety of materials and processes, such as bonding of surface materials such as plastics, fabrics, and metals.

The working principle of a dispensing machine can be briefly divided into the following steps:

Glue preparation: The glue is transported to the dispensing head through a pipe.

  • Automatic control: The control system of the dot glue machine controls the amount of glue released, the coating time and the position accuracy according to the preset program.
  • Precise coating: Through the dispensing head, the glue is accurately applied on the target surface, usually fabric, plastic, silicone and other materials.
  • Curing: The glue after coating will be cured by heat treatment or ultraviolet light to ensure that the glue is firmly bonded.

When making seamless bras, the accuracy of the dot glue machine is crucial to ensure that the glue is applied in the right place to achieve a seamless connection.

2. Application of dispensing machines in the production of seamless bras

The production process of seamless bras usually involves combining different fabrics and other materials through bonding technology to avoid the stitches and gaps caused by traditional sewing processes. The dot glue machine can accurately control the amount of glue applied while avoiding weak or uneven bonding caused by too much or too little glue.

The following are some specific applications of glue dispensers in the production of seamless bras:

(1) Bonding the inner cup of a bra to the edge of the cup

The inner cup of a seamless bra is usually made of soft fabric and elastic material. During the production process, the inner cup needs to be bonded to the edge of the cup. The glue dispenser can accurately apply glue to the edge of the cup to ensure a seamless connection without any obvious marks.

(2) Bonding the shoulder strap to the bra body

The shoulder strap is an important part of the bra, and its connection to the bra body needs to be firm and inconspicuous. With the glue dispenser, the production line can accurately apply glue to the contact point of the shoulder strap to avoid leaving marks in the traditional sewing process, while ensuring the firmness and comfort of the connection.

(3) Fixing shoulder pads and chest pads in seamless underwear

For some seamless bras designed with shoulder pads and chest pads, the glue dispenser can apply glue around the gasket to firmly fix it in the appropriate position of the bra. Compared with traditional sewing, this method can make the bra look smoother and seamless.

(4) Edge processing

The edge processing of seamless bras is very critical. The glue dispenser can not only help fix the edge of the fabric by applying glue, but also prevent it from fraying or unraveling. Especially at the waistband or leg edge of the bra, the application of the glue dispenser can ensure the comfort and durability of the clothing.

3. Advantages of glue dispensers

The use of glue dispensers to produce seamless bras has many significant advantages. First, the glue dispenser can accurately control the flow and position of the glue, which is crucial for the production of seamless bras. It not only ensures the uniform distribution of glue, but also avoids the seams and stitches that are easily produced in traditional sewing methods.

(1) Improve production efficiency

The automated operation of the glue dispenser can significantly improve production efficiency. The traditional manual gluing process often requires a lot of manpower, while the glue dispenser can complete the gluing in a short time, reducing manual operation errors and increasing the speed of the production line.

(2) Improve product quality

Through precise control, the glue dispenser can ensure that the amount of glue applied to each seamless bra is consistent, thereby improving the consistency and quality of the product. Precise glue coating can not only improve the durability of bras, but also prevent glue from overflowing or adhering to parts that should not be adhered.

(3) Reduce material waste

Compared with traditional manual glue coating, glue dispensers can minimize glue waste. By precisely controlling the amount of glue applied each time, glue dispensers ensure the efficiency of glue use and reduce the waste of raw materials.

(4) Better comfort

The comfort of seamless bras is very important. Glue dispensers can not only avoid hard seams in traditional sewing processes, but also ensure smooth and seamless glue coating, thereby improving the comfort of wearing.

4. Conclusion

Dot glue machine play a vital role in the production of seamless bras. With their precise coating technology and efficient production capacity, glue dispensers have become one of the standard equipment for seamless bra production. It not only improves production efficiency, but also ensures the comfort and quality of seamless bras, meeting the high requirements of modern consumers for underwear. With the continuous development of science and technology, glue dispensing technology will continue to promote innovation and progress in the seamless bra industry.
