Underwear and method of manufacturing the same

By employing a dual synergistic design of an anti-curling body structure and an inner lining with a long-filament yarn support layer in the underwear, the problem of edge curling of underwear pieces on fully automated production lines is solved, improving visual recognition positioning and fit stability, reducing the risk of seam cracking, and achieving efficient automated production and wearing comfort.

AI Technical Summary

Technical Problem

In existing technologies, underwear fabric pieces suffer from visual recognition failure and unstable positioning due to edge curling on fully automated production lines. Furthermore, the lack of seamless joints results in insufficient tear resistance and a risk of cracking. Existing solutions fail to effectively address the coordination problem between the interlayer anchoring structure of the lining fabric and the non-single-layer stress balance of the main fabric.

Method used

The design employs a dual synergistic approach, combining an anti-curling body structure with an anti-curling lining structure containing a filament yarn support layer. Through the interlayer connection structure of the elastic and non-elastic yarn systems, along with continuous linear seams and composite reinforcing strips, a synergistic anti-curling mechanism is formed between the lining and the body. A dot-matrix discontinuous coating structure is used in the adhesive layer to ensure bonding strength and breathability.

Benefits of technology

It improves the reliability of visual recognition and positioning and the stability of automated bonding, reduces the risk of seam cracking, meets the stability and consistency requirements of fully automated production, and maintains the breathability and comfort of the wearer.
