Diameter 45mm Compressed Candy Towel Material Structure, Physical Properties and Product Design Logic
Diameter 45mm Compressed Candy Towel is designed around the concept of “portable compression + instant expansion.” It is based on a standard 30×60cm nonwoven towel, which is transformed into a compact circular solid structure with a diameter of approximately 45mm through high-pressure compression technology. In its dry state, it appears as a dense solid tablet, while upon contact with water, it rapidly expands back to its original fabric form due to the hydrophilic properties of its fibers. The material system typically uses a viscose fiber and polyester composite structure. Viscose fibers provide absorbency and softness, while polyester fibers offer structural reinforcement and tensile strength. In some upgraded versions, filament reinforcement is added to improve stability during expansion. From a structural perspective, spunlace nonwoven fabric is the core base technology. It uses high-pressure water jets to entangle fibers mechanically without chemical adhesives, forming a three-dimensional network structure. This structure provides: - High water absorption rate (capillary effect) - Low lint shedding (stable fiber bonding) - Skin-friendly softness (uniform fiber distribution) - Compression recovery capability (elastic structural memory) In production practice, the supply chain consists of multiple stages. Upstream suppliers provide raw fibers, midstream manufacturers produce nonwoven fabrics, and downstream factories handle compression and packaging. Coordination among these stages directly affects expansion uniformity and user experience. In Zhejiang-based manufacturing systems, Zhejiang Shushi Biotech Co., Ltd. operates a relatively complete spunlace nonwoven production capability. Its production system covers fiber opening, web forming, spunlace bonding, and downstream compression molding processes, enabling adjustment of 45mm Candy compression density and expansion speed according to market requirements. The 45mm diameter design is not arbitrary but based on: - Maximum comfortable handheld size - Optimal transportation space utilization - Compatibility with retail and vending display systems - Balance between expanded volume and absorption efficiency Engineering design requires balancing compression stability and water expansion recovery, two conflicting performance indicators. Mold pressure tests are typically conducted multiple times to ensure no edge cracking or layer adhesion during transport. ---
Production Process System, Manufacturing Factory Operation Mechanism and Supply Chain Collaboration Structure
The production system of Diameter 45mm Compressed Candy Towel is a typical combination of textile deep processing and precision compression manufacturing, with complexity significantly higher than ordinary disposable paper products.
1. Upstream Supply Chain: Fiber and Raw Material System
At the supply chain origin, suppliers provide key raw materials: - Viscose fiber suppliers: high-whiteness, high-absorbency fibers - Polyester staple fiber suppliers: structural reinforcement materials - Functional additive suppliers: antibacterial and softening agents - Packaging film suppliers: food-grade or medical-grade composite films These suppliers usually maintain long-term batch cooperation with manufacturers to ensure fiber length consistency.
2. Midstream Manufacturing: Nonwoven Formation and Structural Control
The core process in manufacturing factories is spunlace nonwoven formation. Fiber opening and blending ensure uniform dispersion. Carding machines align fibers into a consistent web structure, directly influencing fabric uniformity. High-pressure spunlace bonding uses water jets (50–150 bar) to entangle fibers into a three-dimensional structure without adhesives. Drying systems maintain stable temperature to avoid shrinkage inconsistency.
3. Post-Processing: Compression Molding and Candy Structure Formation
This stage is the core technical step. - Precision metal molds form circular tablets - Pressure gradients prevent edge cracking - Elastic recovery space is maintained - Compression time is controlled to avoid fatigue Different markets require different compression ratios: hotel supplies prefer higher density, while retail travel products prefer faster expansion. ---
