Speciality Textile Sizing Starch
for High-Performance Weaving
KAG-SIZE | SEVAGRAM EXCIPIENTS
KAG-SIZE is a specially modified textile sizing starch developed by Sevagram Excipients to meet the evolving requirements of the modern textile industry. Engineered specifically for warp sizing applications, KAG-SIZE is widely used for wool, rayon, linen, and blended yarns, where consistent strength, flexibility, and weaving efficiency are critical to productivity and fabric quality.
Textile sizing is one of the most important preparatory processes in weaving. During high-speed weaving, warp yarns are subjected to continuous friction, tension, and mechanical stress as they pass through heddles, reeds, and other loom components. Without adequate protection, yarn breakage increases, loom efficiency drops, and fabric defects become frequent. KAG-SIZE functions as an effective textile binder starch, forming a protective and uniform coating around warp yarns that significantly improves their resistance to abrasion and stress.
Importance of Textile Sizing
Textile sizing involves applying a thin adhesive layer on warp yarns before weaving. The primary objective is to strengthen the yarn and reduce breakage during loom operation. A well-formulated sizing agent must deliver strong adhesion, good film formation, controlled flexibility, and easy removability during desizing. Starch has remained the most widely accepted sizing material because it naturally fulfills these requirements while remaining cost-effective and environmentally responsible.
However, native starch often has limitations in terms of viscosity control, penetration, and film flexibility. To overcome these challenges, modified starches such as KAG-SIZE are developed. Through controlled chemical modification, KAG-SIZE achieves consistent viscosity, deeper yarn penetration, and improved anchoring to fibers, making it suitable for demanding textile operations.
What Makes KAG-SIZE the Best Speciality Modified Starch?
KAG-SIZE is not a general-purpose starch. It is a textile-grade, speciality modified starch processed specifically to enhance performance during warp sizing. The modification improves solubility, stability, and film strength, allowing the starch to penetrate the yarn structure rather than remaining on the surface.
Once applied, KAG-SIZE enters the yarn matrix and bonds effectively with individual fibers. This internal reinforcement reduces surface brittleness, minimizes flaking and droppings, and ensures that the sizing is not visibly noticeable in the final fabric feel. As a result, fabrics maintain a natural handle while benefiting from improved weaving performance.
Key Features of KAG-SIZE
KAG-SIZE offers several performance-driven features that make it a preferred textile sizing binder:
- Superior penetration into warp yarn structure
- Strong anchoring to starch film, reducing flaking and dust formation
- Improved abrasion resistance under high loom speeds
- Uniform size distribution without harsh or stiff fabric feel
- Availability in a wide viscosity range to suit different yarn counts
- Stable performance even under over-drying or variable process conditions
These characteristics allow KAG-SIZE to perform reliably across diverse textile setups, from conventional looms to modern high-speed weaving machines.

Performance Benefits in Weaving Operations
The effectiveness of a sizing starch is ultimately measured by its impact on weaving efficiency. KAG-SIZE delivers tangible operational benefits, including:
- Reduced warp yarn breakage and fewer loom stoppages
- Improved loom efficiency and higher production output
- Enhanced yarn strength without excessive stiffness
- Reduced linting and cleaner weaving environments
- More consistent fabric texture and appearance
By forming a cohesive yet flexible film around the yarn, KAG-SIZE acts as both a protective coating and a functional binder, enabling smoother yarn movement through loom components.
Compatibility with Different Yarn Types
KAG-SIZE is suitable for a wide range of yarn systems, including:
- Wool yarns requiring flexibility and gentle film formation
- Rayon and linen yarns that demand good penetration and adhesion
- Blended yarns combining natural and man-made fibers
Its controlled viscosity and film properties allow textile manufacturers to fine-tune sizing formulations based on yarn type, loom speed, and desired fabric characteristics.
Applications in the Textile Industry
KAG-SIZE is widely used across multiple stages of textile processing, including:
- Warp sizing in weaving preparation
- Textile sizing for improved yarn strength and abrasion resistance
- Fabric finishing and preparatory treatments
- Support applications in textile dyeing and printing processes
Its versatility makes it suitable for both small-scale weaving units and large integrated textile mills.
Sustainability and Process Efficiency
Starch remains one of the most sustainable sizing materials available to the textile industry. Being plant-derived and biodegradable, starch-based sizing agents support environmentally responsible manufacturing practices. KAG-SIZE retains these natural advantages while offering enhanced performance through modification.
Additionally, starch-based sizing agents are easily removable during desizing using enzymatic treatments, ensuring minimal fiber damage and reduced chemical load in wastewater streams.
This contributes to cleaner downstream processing and lower operational costs.
Packaging and Supply
KAG-SIZE is supplied in industry-standard packaging formats to support efficient handling and storage:
- 25 kg bags
- 50 kg bags
- Jumbo bag packaging
Packing materials include HDPE woven bags and paper bags, suitable for both domestic and export requirements. Product consistency is maintained across batches to support uninterrupted textile operations
