[Technological breakthrough] Soonercleaning's 'two-step' wood pulp spunlace nonwovens: reshaping the industry benchmark with innovative technology
At a time when high-end manufacturing has increasingly stringent requirements for material performance, wood pulp spunlace fabrics produced by the traditional one-step method often face industry pain points such as insufficient strength, uneven color, and fiber shedding.
The "papermaking + spunlace" two-step process innovatively developed by Soonercleaning breaks through the limitations of traditional production models and provides more competitive material solutions for medical protection, precision industry, high-end care and other fields.
Technological breakthrough: two-step method achieves a qualitative leap
Different from the conventional process of directly mixing wood pulp and chemical fiber for spunlace, our original "papermaking first and then spunlace" technical path fundamentally improves product performance through physical reconstruction:
Step 1: Papermaking process creates a dense substrate
Use special papermaking equipment to evenly stack wood pulp fibers to form a fiber network with a stable structure. The key issues in this stage are:
Fiber uniformity: Eliminate the problem of uneven mixing of short wood pulp fibers and long chemical fibers in traditional processes
Building basic strength: Forming a continuous fiber layer with initial strength
Fine pore control: Establishing an adjustable three-dimensional pore structure
Step 2: Hydroentanglement
Multi-level hydroentanglement reinforcement is carried out on the basis of papermaking substrate, and the following is achieved through exclusive water needle impact:
Three-dimensional entanglement: Forming a composite structure with a dense surface layer and a fluffy inner layer
Fiber fusion reinforcement: The tightness of the combination of wood pulp and chemical fiber (polypropylene fiber, polyethylene fiber) is significantly improved
Surface fine treatment: Obtain a smoother and softer touch
Core advantages
Compared with traditional processes, two-step products show significant advantages in three key dimensions:
1. Breakthrough in mechanical properties
Strength improvement: The longitudinal tensile strength is more than 30% higher than that of conventional products, which is more suitable for processing by automated packaging equipment
Flexibility and toughness: The special structural design makes the material both stiff and flexible
Durability upgrade: The fiber structure can still be maintained after repeated rubbing
2. Innovation in color performance
Uniform dyeing: The uniformity of the substrate improves the dyeing penetration and reduces the color difference by 99%
Stable color development: The color can still be bright after high-temperature disinfection or liquid immersion
Environmental certification: It adopts food contact certification
3. New standard of cleanliness
Ultra-low lint: less fiber shedding than traditional products, meeting medical device grade requirements
Smooth surface: unique spunlace treatment makes the edge of the material burr-free
Cleanliness guarantee: the entire process is completed in a 100,000-level cleanroom
Accurately meet the needs of multiple scenarios
Based on the two-step core technology, we have developed targeted solutions:
1. Medical protection field
Surgical drapes, surgical gown materials, tray pads: passed ethylene oxide sterilization verification, meeting international standards
Medical hand towels: adapted to high temperature and high pressure disinfection process, no risk of stratification

2. Industrial precision wiping
Electronic industry: The fiber-free property is perfectly adapted to LCD screen and optical lens cleaning
Mechanical manufacturing: High liquid absorption performance quickly removes oil stains without leaving residue on the surface
Semiconductor industry: Passed clean room certification and meets the requirements for wiping precision components
3. Consumption upgrade field
