Core Strengths

1. Fabric and Craftsmanship

Fabrics meet the national standard GB18401-2010 for textile safety, sourced from long-term partners like Huafon Spandex and Luthai Textile. They offer superior breathability, colorfastness, and wrinkle resistance. Printing uses eco-friendly water-based inks certified to OEKO-TEX Standard 100, suitable even for food and medical industries.

Mastering 28 printing techniques—including embroidery, screen printing, heat transfer, DTG (direct-to-garment), foam printing, flocking, 3D thick board, glow-in-the-dark, reflective, fluorescent, foil, prismatic reflective, laser, towel embroidery, patch embroidery, and tatami embroidery—SeekTee achieves colorfastness levels of 4-5, ensuring long-lasting wear.

SeekTee has served over 70,000 corporate clients. Examples: 50,000 custom T-shirts for a major restaurant chain using antibacterial fabric with reflective strips; IP collaboration T-shirts for a tech company with 3D printing; and 2,000 pieces delivered within 72 hours for a university sports event. Clients include Tencent, IMAX, Midea, Huawei, Changan Auto, and J&T Express.
