Product introduction

Protecting Colours from UV Fading

TY-8807A1 Lightfastness Enhancer is a specially formulated blend of organic compounds that effectively absorbs ultraviolet (UV) radiation within sunlight.

By mitigating the destructive effects of UV rays on the dye's chromophores, it significantly enhances the lightfastness of dyes. This product is suitable for improving the lightfastness of various fabrics while also imparting excellent UV resistance.

Key Characteristics and Performance Advantages

Significant Lightfastness Enhancement: Possesses a strong UV absorption capability, which effectively enhances dye lightfastness.
Convenient Application: Offers flexible application and can be used alone or co-processed with dyes.
Durable and Wash-Fast: Provides a wash-fast finish, ensuring the lightfastness enhancement remains effective for a long-lasting period.
Colour Safe: Has minimal impact on the fabric's colour appearance.

Particle Size: 1-20μm

Recommended Application Methods

1. Impregnation (Immersion) Method

Dosage: 2–5% (o.w.f)
Process: Treat at 45–55°C for 30 min → Dehydration → Drying → Setting.
(Setting conditions should be adjusted according to actual fabric temperature requirements.)

2. Padding Method

Dosage: 20–50 g/L
Process: Pad → Dry → Set.
(Setting conditions should be adjusted according to actual fabric temperature requirements.)

Important Usage Precautions

Pre-Testing Recommended: The effectiveness of lightfastness enhancement is influenced by multiple factors (e.g., weave structure, colour depth, dye type). It is essential to conduct small-scale sample testing to confirm application results.
Compatibility: When used in the same bath with other finishing auxiliaries, compatibility testing should be conducted beforehand.

Scope of Application

Suitable for enhancing the lightfastness of various fabrics while imparting excellent UV resistance.

Packaging and Storage

Packaging: Available in 50 kg and 125 kg plastic drums.
Storage: When stored at ambient temperature in its original packaging, this product presents no operational or storage difficulties.
Shelf life: 6 months.
