First, match the fabric properties and select the appropriate product type.
The core premise of selection is to first clearly define the type of fabric you are processing, as different fabrics require vastly different softener properties. For pure cotton knitwear, which emphasizes a fluffy and soft feel, prioritize amino silicone oils with an ammonia value of around 0.6; for pure polyester and linen fabrics, which prioritize smoothness and luster, choose modified silicone oils with a low ammonia value of 0.3; for light-colored and white fabrics, avoid ordinary amino silicone oils with a high risk of yellowing and prioritize low-yellowing modified versions; for sportswear and close-fitting fabrics, both softness and hydrophilicity are important, so choose polyether block-modified hydrophilic silicone softeners to avoid problems such as water repellency and sweat-wicking after finishing.

Verify Manufacturer Qualifications and Avoid Non-Original Supplier Traps
Prioritize reputable manufacturers with large-scale production bases and core technology patents. These manufacturers have been market-tested for many years, have mature quality control systems, and exhibit minimal batch-to-batch product performance differences, avoiding frequent delamination and fluctuations in feel. Avoid intermediaries without their own production capacity. These channels not only have higher procurement costs, but also make it difficult to quickly trace and resolve quality issues later. Request complete quality inspection reports from manufacturers to confirm that the content of restricted substances such as heavy metals, APEO, and D4/D5 in the product complies with international environmental standards such as OEKO-TEX and REACH, avoiding compliance risks in subsequent export stages.

Conduct on-machine testing first to balance cost-effectiveness and service.
Avoid large-scale direct purchases. Request free samples from manufacturers and conduct small-batch on-machine testing under your existing process conditions. Focus on verifying hand feel stability, yellowing, wash resistance, and whether the working fluid causes oil seepage and roller sticking. Don't blindly pursue expensive imported products, nor choose low-priced generic products far below market price. Prioritize manufacturers that produce directly from the source. This ensures reasonable ex-factory prices and access to technical support. If process compatibility issues arise, the technical team can quickly provide on-site adjustments and modify the formula according to actual production conditions, significantly reducing hidden losses from subsequent rework.
