ZETESAL – Powerful Fixing Agents for Polyamide

With LERTISAN, Zschimmer & Schwarz offers high-performance finishes for staple fibers and nonwovens. The products ensure precise control of fiber properties and reliable process performance.

Hygiene applications are the largest consumer of staple fibers and nonwovens, and many of our LERTISAN types are specifically designed for this application field. Modern hygiene applications place diverse and highly specific demands on fiber performance, from rapid liquid absorption and controlled wetback behavior to softness and long-term functionality. To address these diverse requirements, a tailored product portfolio is essential.

LERTISAN HE 1800 provides one-time hydrophilicity and can be used as primary and secondary spin finish for polypropylene and polyester staple fibers. For applications requiring durable hydrophilicity combined with enhanced softness, LERTISAN HD 1022 offers a reliable solution. As part of our next-generation portfolio, LERTISAN HD 1095 features an optimized emulsion stability making it particularly suitable for high-concentration emulsions in kiss roll applications. It delivers fast liquid absorption, and a pleasant textile touch on spunbond nonwovens.

Key Benefits:

📋 Selected grades with FDA-compliance

💧 Excellent liquid transport for hygiene applications

🧵 Soft textile touch

🌱 Fully bio-based grades available

With its FASAVIN TC range, Zschimmer & Schwarz offers high-performance spin finishes for technical yarns used in demanding applications such as airbags, safety belts and other industrial fabrics. High-tenacity yarns must withstand extreme process speeds and temperatures while ensuring consistent performance in downstream applications.

FASAVIN TC grades are engineered to deliver the required yarn properties directly during extrusion. Depending on the polymer type, they provide temperature resistance up to 250 °C and ensure reliable processing in modern high-speed spinning processes.

The versatility of the spin finish portfolio can be illustrated by selected examples: FASAVIN TC 1388 is specifically tailored to the reliable performance and long-term stability of airbag yarns in automotive safety systems. FASAVIN TC 1345 is optimized for tire cord.

Key Benefits:

🔥 Temperature-resistant up to 250 °C

⚡ Designed for high-speed spinning processes

⚙️ Spin finishes designed for high-tenacity yarns available

🏭 Reliable and consistent performance

With ANTHYDRIN, Zschimmer & Schwarz offers effective water-repellent solutions designed to meet modern environmental requirements. The ANTHYDRIN product line comprises fluorine- and silicone-free finishes that avoid critical substances such as PFOS and PFOA while maintaining excellent performance.

Despite being fluorine-free, ANTHYDRIN provides very good water repellency and wash resistance, combined with a pleasant soft handle.

ANTHYDRIN CFC is a durable water-repellent finish for synthetic fibers and their blends, while ANTHYDRIN DNF is a paraffin-based solution suitable for a wide range of textile substrates, providing reliable water repellency and a soft handle.

Key Benefits:

🌿 Fluorine- and silicone-free formulations

💧 Effective water repellency with good wash resistance

🧵 Suitable for all kinds of fabrics and materials

🪶 Soft handle for comfortable textile performance

With FASALOOP, Zschimmer & Schwarz enables full recyclability for artificial turf and carpet systems. Conventional constructions rely on multi-material composites using SBR-latex or polyurethane backings. At the end of life, the complex material structure makes separation for recycling particularly challenging.

FASALOOP replaces conventional backings with advanced polyester- and polyolefin-based systems. This enables the design of mono-material constructions that can be recycled without complex material separation.

In artificial turf applications, polyolefin fibers tufted into a polyolefin primary backing can be combined with a polyolefin-based FASALOOP secondary backing, allowing the entire system to be recycled as one material stream. The same principle applies to polyester-based carpet constructions, including automotive interiors.

FASALOOP represents a decisive step toward closing material loops and reducing the overall CO₂ footprint.

Key Benefits:

♻️ Enables mono-material systems for full recyclability

🔄 Eliminates complex material separation at the end of life

🌍 Reduces overall CO₂ footprint

🚗 Suitable for artificial turf and automotive carpet systems

The speed and efficiency of moisture transport have a decisive impact on garment comfort. Functional fabrics with wicking properties enable sweat and moisture to be transported away from the skin to the outer fabric surface, where they can evaporate more easily.

However, untreated synthetic textiles such as polyester and polyamide are inherently hydrophobic and therefore show limited moisture transport performance.

HYDROSET ECO-DRY has been specifically developed to enhance the wicking performance of synthetic fabrics. Based on nature-derived technology, it supports efficient moisture transport from the skin to the fabric surface, promoting faster evaporation.

The result is improved drying performance, enhanced breathability, and long-lasting wearing comfort in sports and activewear applications.

Key Benefits:

💧 Enhanced moisture transport and quick drying

🌿 Odor control and long-lasting freshness

🧵 Suitable for polyester, polyamide and their blends
