The problem of static electricity is a technical problem that has plagued the textile industry for many years, especially in the processing and use of synthetic fibers. With the development of modern textile products towards functionalization and high-end, antistatic agents have become key additives to enhance the added value of textiles and user experience.

This article will analyze a specific application case and discuss the innovative application of antistatic agents in the textile chain with everyone's expectations.

Case background

A large knitted fabric manufacturer has long faced the problem of static electricity accumulation in polyester sports fabrics, resulting in a 30% reduction in the efficiency of the subsequent sewing process, and the finished garments are prone to dust absorption in a dry environment, and the consumer complaint rate remains high. The traditional solution uses increasing the humidity of the environment or adding conductive fibers. Although it solves the problem to a certain extent, it has the defects of high cost and affecting the feel of the fabric, and cannot be recognized by industry manufacturers.

Solution

The technical team developed a composite antistatic treatment solution:

Spinning stage: Add permanent polymer antistatic agent to the melt, form a conductive network through the hydrophilic groups in the molecular chain, and reduce the volume resistivity from 10^15Ω·cm to 10^8Ω·cm.

Finishing stage: Use reactive silicone quaternary ammonium salt complex to give the fabric durable antistatic properties through padding process. After 50 washes, the surface resistance remains below 10^10Ω.

Process optimization: Control the treatment temperature at 130-140℃ to ensure the cross-linking and curing of the additives and avoid fiber damage.

Implementation effect

The efficiency of the sewing process is increased by 25%, and the stitch skew rate is reduced to 0.3%.

The static half-life of the finished product is shortened from >60s to 0.5s (GB/T 12703-2021 standard test).

Reducing defective products caused by static electricity by about 1.2 million meters per year, equivalent to saving 4.5 million yuan in costs.

Fabric feel score increased by 15%, and air permeability retention rate>95%.

Technical innovation

Dual action mechanism: combining internal conductive network construction with surface charge neutralization to achieve full-scene protection.

Environmental characteristics: The formula does not contain APEO and heavy metals, and complies with the standard.

Process compatibility: Used in conjunction with flame retardant, antibacterial and other functional finishing agents without affecting performance.

Industry inspiration

This case proves that scientific antistatic solutions need to be considered comprehensively:

Matching of fiber type and product end use.

Balance between durability and comfort.

Synergy with other functional finishing.

Full life cycle cost accounting.
 

With the development of smart textiles, a new generation of environmentally responsive antistatic agents are being developed, which can automatically adjust the conductive properties through humidity and temperature changes in the future. This case provides a replicable technical path for the functional upgrading of the textile industry and highlights the core role of special additives in improving the industry value chain.
