Fabric Selection and Comfort Engineering Technology Analysis

In the system of briefs manufacturer, fabric is one of the core factors determining product competitiveness. Yongrui has established a 500+ fabric selection system, capable of meeting multi-level demands for comfort, functionality, and cost structure in different markets.

Core fabrics include:

• Combed cotton: high breathability and skin-friendliness, suitable for basic underwear

• Lycra: high resilience performance, improving long-term wearing stability
• Silk and imitation silk fibers: used for high-end comfort product lines
• Functional fibers: enhancing moisture-wicking performance
• Leather and special structure materials: used for design-oriented or fashion expression products

In comfort engineering, Yongrui adopts multi-dimensional structural optimization technologies including:

Ergonomic 3D cutting, making underwear fit different body curves
Elastic control system, balancing pressure distribution through spandex ratio adjustment
Frictionless sewing structure design, reducing discomfort during long-term wear
Moisture-wicking treatment process, improving comfort in summer and sports environments

In addition, the company widely applies digital printing and heat sublimation printing technology in underwear production (accounting for about 80%), enabling high-precision pattern reproduction, especially suitable for personalized customization and brand differentiation needs.

Quality Control System and International Certification Standards

In the briefs manufacturer system, quality stability is a core factor determining long-term cooperation. Yongrui has established a complete three-stage quality control system to ensure every batch meets international delivery standards.

The first stage is raw material inspection, where all fabrics must pass multiple tests before entering production, including:

• Color fastness testing (to prevent fading)
• Shrinkage testing (to ensure dimensional stability)
• Tensile and recovery performance testing (to ensure elasticity consistency)

The second stage is production process control, using an online inspection system with multiple checkpoints in sewing, cutting, and assembly processes to monitor deviation in real time.

The third stage is finished product inspection, using the internationally recognized AQL 2.5 sampling standard to ensure batch consistency and shipping stability.

In terms of certification systems, Yongrui has passed:

• ISO 9001 quality management system certification
• OEKO-TEX Standard 100 textile safety certification
• BSCI social responsibility audit standard (meeting international procurement requirements)

These certifications ensure products can smoothly enter mainstream European and American retail systems and cross-border e-commerce platforms while meeting compliance and safety requirements.

Full Production Process Analysis (From Design to Shipment)

• Fabric preparation and inspection: All fabrics must complete gram weight, color fastness, shrinkage, and elasticity testing before production to ensure material consistency and stability.
• Automated cutting and layout: High-precision automatic cutting machines are used, and scientific layout improves fabric utilization while ensuring uniform cutting dimensions.
• Sewing and structural assembly: Flat stitching, overlocking, and seamless bonding processes are used to assemble structures, precisely combining waistband and fabric to improve comfort and durability.
• Printing and pattern application: Digital printing, heat sublimation, and screen printing are flexibly applied to achieve high-precision reproduction of brand patterns and logos.
• Quality inspection and in-line control: Multi-point inspection systems monitor stitching and dimensions in real time, with semi-finished product sampling to ensure batch consistency.
• Finishing and shaping: Standardized ironing processes stabilize fabric structure and surface smoothness, ensuring uniform product quality.
