Professional Women's Seamless Knitwear Manufacturer

An overseas customer (*** company) ordered 12,000 pieces of seamless sports bras (style ***) in March 2024, shipped in two batches. After the second batch of 6,000 pieces arrived at the port, the customer's warehouse inspection found that approximately 35% of the products (2,100 pieces) had obvious color differences, inconsistent with the approved sample; additionally, about 15% (900 pieces) had size measurements exceeding the allowable tolerance (M size bust 2-3 cm larger), making them unsellable. The customer requires a full return and replacement, and that we bear the resulting air freight and customs clearance costs.

Our company immediately arranged for the quality inspection team to re-check the retained samples and production records, confirming that the color difference issue was caused by improper control of the dye lot difference in this batch of fabric, while the size deviation was due to abnormal tension parameters of the cutting machine. After consultation with the customer, the following plan was adopted: 1) All 6,000 pieces that have arrived at the port will be returned to our overseas warehouse; 2) Products with color difference will be re-dyed (approximately 2,100 pieces), products with size deviation will be repaired and re-finished (approximately 900 pieces), and the remaining 3,000 pieces will be retained at the original price after passing full inspection; 3) After repair, products will be inspected by a third-party inspection agency (SGS) and then re-shipped, with air freight costs borne by our company; 4) Additionally, 300 pieces will be supplied free of charge as compensation for the customer's inventory losses caused by this quality issue; 5) For subsequent orders, full inspection before shipment and third-party inspection procedures will be added.

A B2B bulk purchasing customer from Europe (Customer Code: ***, Order Number: ***) reported that after receiving the 10,000 seamless yoga pants we shipped, their local factory encountered issues during batch production when replicating our provided production process parameters on the customer's own seamless machines: frequent needle breakage, uneven fabric density, and poor waistband elastic recovery. This resulted in a 12% scrap rate for the first 500 pieces. The customer demands immediate remote technical support from us, otherwise they will suspend the subsequent 40,000-piece reorder and claim compensation.

Our company immediately initiated remote technical support services: connecting with the customer's factory technical team via encrypted video conferencing software (***), remotely guiding the customer's operators to inspect the machine item by item. First, we verified the differences between the customer's machine model (***) and our sampling machine model, confirming the need to adjust the yarn feeding tension parameters (from *** to ***) and the knitting cam angle (from ***° to ***°). Second, we remotely transmitted our latest process files optimized for this style (including course arrangement, rubber yarn feeding ratio, and heat-setting temperature curve), and demonstrated the debugging operations at key nodes step by step through screen sharing. Meanwhile, we arranged for an after-sales engineer to be online for 8 hours, monitoring the customer's trial knitting of 200 sample pieces in real time, and fine-tuning the take-up and winding speed (reduced by 15%) and heat-setting time (extended by 20 seconds) based on Moiré pattern and stretch-recovery data. Finally, we remotely guided the customer to calibrate the equipment sensors and recommended replacing them with special knitting needles of model *** to reduce friction.
