Rapiddirect FAQs


Yes, we provide free standard samples (A4 size or small cones) of our Nylon and Polyester yarns for quality testing. Customers only need to cover the express shipping fee. This allows you to verify the hand-feel, strength, and color accuracy before placing a bulk order, ensuring our products meet your specific textile manufacturing requirements.

We use advanced spectrophotometers and digital color management systems to minimize lab-to-bulk variance. Every batch of dyed yarn undergoes rigorous testing under standard light sources (D65/TL84). By maintaining strict control over dye formulations and water quality, we guarantee a high level of color consistency (Delta E < 1.0) for all repeat orders.

Absolutely. Our manufacturing facility is fully certified by OEKO-TEX Standard 100 and GRS (Global Recycled Standard). We ensure that our yarns are free from harmful substances and are produced through sustainable processes. We can provide full certification reports to support your brand’s commitment to environmental compliance and sustainable fashion development.

For standard products like Polyester Sewing Thread, the lead time is usually 15-20 days. For customized or functional yarns involving specific dyeing or treatments, it may take 25-30 days. Our streamlined supply chain management ensures efficient production and timely delivery, helping you maintain a stable inventory and meet your downstream production deadlines.

For our standard white yarns, there is no strict MOQ. However, for custom-dyed functional yarns (such as anti-bacterial or flame-retardant), the MOQ is typically 500kg per color. This ensures cost-effectiveness in the dyeing process. We also offer flexible solutions for smaller trial orders to support emerging brands and new product development projects.

Yes, we provide comprehensive Technical Data Sheets (TDS) for our entire product range, including Nylon, Polyester, and Covered yarns. These documents detail essential physical properties such as denier, tenacity, elongation, and twist per meter. Having this data allows your engineering team to optimize machine settings for better weaving or knitting performance.

We stand by our quality. If any batch fails to meet the agreed-upon specifications, our after-sales team will initiate an investigation within 24 hours. Once the discrepancy is confirmed via sample testing, we offer solutions including replacement, discount, or refund. Our goal is to build long-term partnerships based on transparency, accountability, and mutual trust.
