The Weaving Process of Knitted Underwear Fabrics

As an important garment that people wear closely, underwear has extremely high requirements for comfort and aesthetics, and the quality and comfort of its fabrics directly affect the wearing experience of consumers. Understanding the weaving process of knitted underwear fabrics helps us to better meet market needs and improve the quality of underwear.

1. Yarn selection and preparation

The weaving process of knitted underwear fabrics begins with the selection and preparation of yarns. First of all, according to the quality requirements, wearing comfort and aesthetics of underwear fabrics, select suitable raw material fibers, such as cotton, silk, wool, chemical fiber, etc. These raw fibers are then spun and processed into yarns that meet the requirements. The quality of the yarn directly affects the quality of the subsequent weaving and fabric, therefore, the selection of yarn must be strictly controlled to ensure that it has good physical properties and chemical stability.

2. Weaving and forming on the machine

After the yarn is ready, it enters the weaving stage on the machine. According to the designed underwear style and fabric requirements, choose the appropriate knitting machine model and weaving process. The knitting machine weaves the yarn into knitted fabric with a certain structure and performance through the up and down reciprocating movement of the knitting needle.

In the weaving process, the movement speed and tension of the knitting needles need to be strictly controlled to ensure the uniformity and stability of the fabric.

3. Preliminary treatment of fabrics

Preliminarily formed underwear fabrics require a series of treatments to improve their performance and appearance. First of all, the slurry residue on the surface of the fabric is removed through the desizing process to improve the softness and moisture absorption of the fabric. It is then washed and dried to remove stains and impurities from the fabric while bringing it to a certain degree of dryness.

4.Shrinkage and styling treatment

Shrinkage and styling are the key steps in the weaving process of knitted underwear fabrics. Because yarns and fabrics are prone to deformation when subjected to external forces, shrinkage treatment is required to make the fabric shrink to a stable state under certain temperature and humidity conditions. The setting treatment is to make the fabric reach a predetermined shape and size by means of hot pressing or steam, etc., to improve the dimensional stability and wrinkle resistance of the fabric.

5. Calendering and shearing process

After shrinkage and styling, the fabric enters the calendering and shearing process. Calendering is the use of calenders to pressurize and heat the fabric to make the surface of the fabric smoother and smoother, and improve the gloss and feel of the fabric. Shearing is to remove fluff and pilling on the surface of the fabric, making the fabric more neat and beautiful.

6. Sizing and color processing

In the sizing and coloring treatment stage, first through the sizing process, the surface of the fabric is coated with a thin layer of slurry to improve the stiffness and wear resistance of the fabric. Then, according to the color requirements of the underwear fabric, the color enhancement process is carried out to make the fabric present a rich color and texture effect. In this process, the amount and ratio of slurry and dye need to be strictly controlled to ensure the quality and environmental protection of the fabric.

7. Quality inspection and evaluation

After the above process treatment, the knitted underwear fabric needs to be inspected and evaluated for quality. Through the appearance of the fabric, physical properties, chemical properties and other aspects of comprehensive testing ensure that the fabric meets the design requirements and related standards. Fabrics that do not meet the requirements need to be reworked or scrapped to ensure the quality and safety of the final product.

During the quality inspection process, the wearing comfort, breathability and warmth of the underwear also need to be evaluated to ensure that the product meets the needs and expectations of consumers.

8. Packaging and finished products leave the factory

Finally, the knitted underwear fabrics that have passed the quality inspection are packaged and labeled, and then shipped out as finished products. In the packaging process, it is necessary to choose the appropriate packaging materials and methods to ensure that the fabric is not damaged and contaminated during transportation and storage. At the same time, it is also necessary to indicate the name, specification, production date and other information of the product on the packaging, so that consumers can identify and purchase.

Summary

The weaving process of knitted underwear fabrics is a complex and delicate process, involving multiple links and processes. From yarn selection and preparation to packaging and finished product delivery, every link needs to be strictly checked and controlled to ensure the quality and performance of the final product. At the same time, with the advancement of science and technology and changes in the market, the production process of knitted underwear fabrics is constantly innovating and improving to meet the growing needs and expectations of consumers.
