Kr-521 Softener Flake represents a significant advancement in textile auxiliary agents, specifically designed to impart superior softness and handle to a variety of fabrics. This innovative product, composed of multiple polymeric compounds, is presented in a convenient flake form, making it easy to handle and dissolve for various applications in the textile industry.

One of the key advantages of Kr-521 Softener Flake is its exceptional eco-friendly profile combined with crucial low yellowing properties. Unlike some traditional softeners that can cause discoloration over time or upon heating, Kr-521 minimizes this effect, ensuring that the original whiteness and color shade of the fabric are preserved. This makes it particularly valuable for white and pastel-colored textiles where maintaining color integrity is paramount.

The performance benefits are notable. Fabrics treated with Kr-521 exhibit enhanced softness, a smooth surface feel, and a desirable fuller handle or 'hand feeling'. This significantly improves the aesthetic and tactile quality of the finished textile products. Furthermore, Kr-521 demonstrates excellent resistance to both salt and alkali conditions, making it an ideal auxiliary for fabrics that undergo dyeing processes involving high salt concentrations or subsequent finishing steps requiring alkali resistance.

Applications are diverse, including use as both a dyeing auxiliary and a post-processing auxiliary. It is particularly well-suited for fabrics requiring robust salt tolerance. The product can be applied through two primary methods: Padding and Dipping. For the padding method, a dosage of 20~30g/L (using a 10% solution) at 30ºC~40ºC is recommended for a single dip and pad or double dips and pads. The dipping method utilizes a dosage of 3~8% (o.w.f) with a 10% solution at 40ºC~50ºC, a liquor ratio of 1:10~15, and a treatment time of 30 minutes. It is always advised to test compatibility when using Kr-521 with other auxiliary agents.

Dissolving Kr-521 Softener Flake is straightforward. It can be dissolved using hot water. One method involves gradually introducing the flakes into room temperature water at a 5~10% ratio, stirring for 3~5 minutes while gently heating to 70~75ºC, and continuing to stir until fully dissolved. Alternatively, flakes can be introduced directly into water heated to 60~70ºC at the same 5~10% ratio, stirring slowly until complete dissolution is achieved. Once dissolved, the solution is ready for use.

For storage and packaging, Kr-521 Softener Flake should be kept in a cool and shaded location. Under these conditions, it maintains stability for up to 12 months. The product is typically packaged in 25kg plastic woven bags for convenient transport and storage.

As a versatile and high-performing textile softener, Kr-521 Softener Flake offers manufacturers a reliable solution for achieving desired fabric properties while adhering to environmental considerations and maintaining color quality.
