Automatic Long Filament Curl Shrinkage Tester

The Automatic Long Filament Curl Shrinkage Tester is designed to measure boiling water shrinkage rate, dry heat shrinkage rate, curl shrinkage rate, curl modulus, and curl stability of synthetic fibers. With automatic load adjustment, auto-loading, timing, length measurement, and zero calibration during testing, results are calculated and printed automatically. This instrument is ideal for quality control, R&D, and educational applications in textile and fiber industries.

Application

(1) Synthetic Fibers: Polyester, nylon, polypropylene, acrylic, and other long synthetic filaments.

(2) Filament Yarns: Single filament yarns, multifilament yarns, twisted yarns, and textured yarns.

(3) Textile Products: Knitted fabrics, woven fabrics, industrial textiles, and composite yarn-based materials.

(4) Home Textiles & Apparel: Curtains, upholstery, carpets, sportswear, and hosiery.

(5) Industrial & Technical Textiles: Ropes, fishing lines, seatbelts, filtration materials, geotextiles, and reinforcement fibers.

(6) R&D & Quality Control: Testing heat or moisture shrinkage behavior, curl stability, and modulus to optimize processing and performance.

(7) Educational & Training Use: Demonstrating filament shrinkage and curl behavior in textile laboratories and classrooms.

Standards

(1) GB/T 6506: Synthetic fiber boiling water shrinkage test

(2) GB/T 6505: Synthetic fiber dry heat shrinkage test

(3) ASTM D6774-22: Standard test method for synthetic filament shrinkage

Features

(1) Automatic load adjustment and application ensures precise force during testing.

(2) Auto-loading, timing, and zero calibration for fully automated measurement.

(3) Measures multiple parameters simultaneously: curl shrinkage rate, curl modulus, curl stability, and thermal shrinkage rate.

(4) Supports batch testing up to 30 specimens for high-efficiency evaluation.

(5) Integrated computer system with screen display and printer output for results reporting.

(6) Suitable for various filament yarns and fabrics, allowing broad testing applications.
