Who are Seamless Clothing Manufacturers?

Seamless clothing manufacturers are factories specialising in the production of seamless apparel, using seamless circular knitting machines. China, in particular, is well-known for its extensive garment manufacturing industry and advanced production capabilities. These manufacturers are primarily located in China, Turkey, Italy, and other countries.

What is Seamless Clothing?

Seamless clothing is a one-step garment produced using a specialised Seamless Circular Knitting Machine.

Seamless manufacturing techniques allow for the efficient production of high-quality seamless apparel, utilising advanced technology.

The principle of seamless clothing production involves creating a three-dimensional curved surface with a fixed tube diameter and a consistent number of needles, along with variations in structure and raw materials. This process uses an innovative method—seamless knitting—which enhances the durability, fit, and comfort of activewear, representing a significant advancement in the industry.

Unlike garments made from cutting and sewing traditional knitted or woven fabrics, the torso sections of seamless appareltypically do not involve cutting or sewing limbs, or involve minimal cutting and sewing.

From yarn to ready-made apparel, the production of seamless clothing shapes the neck, waist, buttocks, and other areas without seams, combining comfort, practicality, and style. Seamless clothing also helps manage sweat by providing breathability and moisture-wicking properties, keeping the wearer dry during physical activity.

More seamless knowledge

What material or fabrics does seamless clothing factory
use to make seamless wear?

The fabric of seamless clothing is typically made from two or more types of yarns interwoven through seamless weaving. Many sustainable activewear brands now utilize organic materials, offering eco-friendly and environmentally conscious options. Here, we introduce five commonly used yarn materials, but they are definitely not limited to these five.

1, Cotton.

The permeability, comfort and environmental protection of cotton are irreplaceable by other materials, so we will add a certain proportion of cotton to many products. But now the industry is very developed. Often, there is no cotton in our seamless thermal underwear, but nylon, spandex, polyester and other blended fibers are used.

High-quality cotton yarn used in seamless clothing manufacturing, showcasing its soft texture and durability for creating comfortable activewear

Cotton is a highly valued natural fiber in the world of seamless clothing, especially for seamless activewear and sportswear. Its exceptional breathability and softness make it a top choice for garments that need to perform under pressure, such as during intense workouts or daily active wear. Seamless cotton apparel allows for unrestricted movement, ensuring the body stays comfortable and cool even during the most demanding activities.

2, Nylon.

Nylon is a synthetic fiber renowned for its strength, flexibility, and resilience, making it a staple in seamless clothing production. Particularly favored for seamless sportswear, gym wear, and outer layer garments, nylon delivers a smooth, stylish finish that stands up to the demands of active lifestyles. Its superior durability and resistance to abrasion ensure that seamless activewear made from nylon maintains its shape and performance, even after repeated intense workouts. Versatile nylon spandex yarn used in seamless clothing manufacturing, providing excellent elasticity and support for a comfortable fit in activewear. This high-performance material enhances freedom of movement while maintaining shape and durability.

Seamless activewear manufacturers rely on nylon blends to create garments that are not only cost effective but also high-performing and visually appealing. The smooth texture of nylon seamless clothing enhances comfort and allows for a full range of motion, making it ideal for both performance-driven sportswear and fashionable gym wear. For brands seeking to create stylish, functional, and long-lasting seamless apparel, nylon is an essential material that supports innovation and quality in every garment.

3, Polyester.

Polyester is the most widely used synthetic fiber in the world, surpassing acrylic fiber. Many of our commonly used common polyester only write abbreviated PET or PL.

Polyester is usually blended with other fibers, and a certain percentage of polyester fibers written on many garments are actually polyester. Because the amount of polyester fabric is relatively large, they don’t want ordinary people to think this is a low-grade thing. Sometimes customers also specify high-grade polyester. The high-grade polyester commonly used in our company is a brand of DuPont, called Coolmax.

Polyester is a versatile and high-performance synthetic fiber widely used in seamless clothing, from seamless activewear and sportswear to accessories. Known for its excellent moisture-wicking abilities, breathability, and quick-drying properties, polyester is the go-to choice for garments that need to keep up with an active lifestyle. Seamless polyester apparel ensures a comfortable fit, helps regulate body temperature, and supports optimal performance during any activity.

Seamless activewear manufacturers frequently use polyester blends to produce high-quality seamless apparel that meets the evolving demands of the market. Polyester’s advanced properties, combined with its eco friendly potential, make it a strong candidate for sustainable activewear production. Whether you’re developing seamless clothing for sports, fitness, or everyday wear, polyester offers the durability, comfort, and style that today’s consumers expect from premium seamless garments.

4, Spandex.

This is a polyurethane fiber Elastane fiber. The names of commodities are Lycra (Lycra, USA, UK, The Netherlands, Canada, Brazil), Neolon (Neolon, Japan), Rastan (Dorlastan, Germany), etc.

High-quality elastic rubber yarn designed for seamless clothing production, offering exceptional stretch and recovery. This material ensures a snug fit and enhanced comfort, making it ideal for activewear that moves with the body during intense workouts

Lycra is commonly used in our company. Lycra, spandex yarn, polyester spandex, is a brand of Dupont company. Lycra fiber is a magical material. LYCRA can be freely elongated by 4 to 7 times and quickly returns to its original length after the external force is released. Some of our self-cultivation series include Lycra’s ingredients. The high elastic fiber mentioned in our domestic sales promotion refers to this kind of material.

5, Viscose fiber.

Such as matte silk, viscose, rayon, rayon, artificial wool, etc. Among them, the most famous one is Modal fiber, which is the cellulose regenerated fiber of high wet modulus viscose fiber developed by Lenzing Company of Austria. The raw material of this fiber is European beech, which is first made into wood pulp and then processed into fiber by a special spinning process.

6, Polypropylene fiber.

Polypropylene PP is the Chinese trade name for isotactic polypropylene fiber, a synthetic fiber made from propylene, a by-product of petroleum refining, which is also called polypropylene fiber.

Polypropylene has the following characteristics:

  • The vertical plane is straight and smooth;
  • The density is light, only 0.91g/cm3;
  • High strength, excellent elasticity and good wear resistance;
  • Wet strength is basically equal to dry strength, which is an ideal material for making fishing nets and cables;
  • Moisture absorption and perspiration are obvious;
  • Poor dyeing property;
  • Corrosion resistance, but poor light resistance, poor thermal stability, easy aging, not resistant to ironing;
  • High strength, second only to nylon, but the price is much lower than it. The fabric made of polypropylene fiber has stable size and good wear resistance. Therefore, polypropylene fiber is often used to weave carpets.

Brief Introduction of
Seamless Clothing Knitting Process

Seamless clothing is basically worn close to the body and directly touch the skin, so the feeling of wearing is particularly important. Nylon & spandex, nylon & polyester & spandex, polyester & elastane, nylon & cotton (or Modal) & elastane, etc. all have good moisture absorption and antistatic sex after special dyeing processes, and their protein composition is similar to human skin, so it is soft and comfortable.

Although the cellulose fiber such as cotton hemp also is natural fiber, hygroscopic performance is right, regard seamless knitwear as comfortable also, but their softness and tactility are far inferior to super high quality seamless activewear.

A brief introduction of seamless garment weaving technology.

1, Weaving/ knitting equipment and parameters

  • The equipment

The sm8-TOP2 seamless knitting circular machine produced by SANTONI, Italy, is widely used by seamless activewear manufacturers in China at present. It is a single-sided once-forming computerized knitting jacquard machine with eight paths of yarn, and each path has two independent jacquard point (i.e., needle picker). Each path can carry out 3 levels of weaving at the same time (i.e., at the same time select needles for forming loops, collecting loops and lines).

  • Parameters

Electronic seamless apparel circular knitting machine with barrel diameter of 30-40cm(12-16 inches); The speed of 110 r/min; Needle selector for each 2; The feeding path is 8. Knitting circular machine capacity is 2.2KW, suction motor power is 3.9KW; The yarn guide is 8 / channel (in practical application can be less than 8).

2, Pre-knitting Process

Let’s take the example with silk yarn production way to talk about pre-knititng process.

Because the silk has sericin, and high rigidity. It is easy to appear brittle broken and missing needles and other defects when weaving, so it needs to be dealt a bit before weaving.

If the twisted silk manufactured by the general polyester factory is used, it needs to go through the following processing: the twisted raw silk is placed in the solution containing softening agent (such as ENS-I) and foaming agent (such as HV-302), bath ratio 1:20, temperature 40-50℃ for 18 hours, after drying, winding, and then on the machine weaving.

If the simple raw silk directly provided by the factory is used, it is necessary to put the raw silk in a barrel in a vacuum container containing the treatment solution (generally, the solution of Swire oil with bath ratio of 1:10, 109/L) at room temperature, so that the treatment solution can quickly penetrate into the inner layer of the coil and the inside of the sericin, and the machine is woven after processing.

3, Programming

Then, deal with program design. After determining the number of nozzles and paths, the program is programmed in the special programming system according to the choice of nozzles and paths, and attention should be paid to timely refueling and air suction programming design.

The selection of nozzles should be determined according to the performance of the machine itself. The front nozzles are in the inner layer and the back nozzles are in the outer layer. When weaving the fabric covered with one material and another material, the sand nozzles should be appropriately selected according to the needs.

4, Run on the machine

After the program is prepared, the machine began to debug, in this process should strictly control the size, repeated modification of the program, until reaching the requirements.
