Semi-Cross Lapped Spunlace Nonwoven Fabric

I. Process Flow of Semi-Cross Lapped Spunlace Nonwoven Fabric

The production of semi-cross lapped spunlace nonwoven fabric is a precise and rigorous systematic project. Changshu Yongdeli Spunlaced Nonwoven Fabric Co., Ltd. strictly follows scientific procedures to ensure that each batch of products has excellent quality. The specific process is as follows:

Raw material preparation: High-quality natural fibers (such as cotton fibers), chemical fibers (such as polyester, viscose fibers, etc.) or a mixture of both are selected as raw materials. The company strictly screens the raw materials to ensure that the length, fineness, strength, and other indicators of the fibers meet the production requirements, ensuring product quality from the source.

Opening and blending: The baled fibers are dispersed through professional opening equipment to remove impurities and defects, making the fibers fluffy. Then, blending is carried out according to the preset formula ratio to ensure that fibers of different types and properties are evenly mixed, laying a good foundation for subsequent processes.

Carding and web formation: The opened and blended fibers enter the carding machine, where the needle cloth in the carding machine further combs and straightens the fibers and evenly spreads them into a continuous web. This step precisely controls the thickness and uniformity of the web to ensure a stable web structure.

Semi-cross lapped spunlace reinforcement: This is the core process of semi-cross lapped spunlace nonwoven fabric production. The formed web is conveyed to the spunlace machine, where high-pressure water jets are sprayed onto the web from different angles in a specific cross pattern. Compared with full-cross lapped spunlace, semi-cross lapped spunlace optimizes the water jet angles and cross degrees, ensuring a tight entanglement between fibers to form a stable fabric structure while better preserving the original characteristics of the fibers, enhancing the overall performance of the product. Parameters such as water jet pressure and frequency are precisely controlled by the company's professional technicians based on product requirements.

Dewatering and drying: The wet nonwoven fabric after spunlace reinforcement first enters the dewatering equipment to remove most of the water, reducing the energy consumption of the subsequent drying process. Then, the dewatered nonwoven fabric enters the drying equipment and is dried under suitable temperature and airspeed conditions to reach the standard moisture content, while further improving the flatness and stability of the fabric surface.

Post-treatment and slitting: According to different customer needs, post-treatment is carried out on the dried nonwoven fabric, such as softening, anti-static, and antibacterial treatments, to endow the product with more special functions. Finally, the nonwoven fabric is slit into rolls or sheets of the preset width and length through slitting equipment for convenient use by customers.

II. Advantages of Semi-Cross Lapped Spunlace Nonwoven Fabric

Outstanding mechanical properties: Thanks to the unique semi-cross lapped spunlace reinforcement process, the product has high machine direction and cross direction strength, with a small strength difference. The fabric structure is stable, and it is less likely to tear or break during use, capable of withstanding certain tensile and friction forces, and has a long service life.

Good air permeability and moisture absorption: The semi-cross lapped spunlace process ensures a tight entanglement of fibers while forming a uniform and appropriate pore structure on the fabric surface, giving the product excellent air permeability and the ability to effectively promote air circulation. At the same time, it has good moisture absorption capacity, can quickly absorb and conduct moisture, and is suitable for scenarios that require air permeability and moisture absorption. Excellent flexibility and comfort: During the production process, the characteristics of the fibers are fully considered and retained. The semi-cross lapped spunlaced nonwoven fabric has a soft and delicate touch, providing a comfortable sensation when in contact with the skin without any irritation. It is suitable for use in hygiene products, medical dressings, and other fields that come into direct contact with the human body.

Stable product quality: Changshu Yongdeli Spunlaced Nonwoven Fabric Co., Ltd. has a complete quality control system. Every step from raw material procurement to production processing is strictly monitored. Advanced testing equipment is used to test the performance indicators of the products to ensure that the quality of each batch of semi-cross lapped spunlaced nonwoven fabric is stable and reliable, and the performance parameters meet relevant standards and customer requirements.

High degree of customization: The company has strong technical research and development capabilities and flexible production scheduling capabilities. It can customize production in terms of fiber type selection, weight control, and post-treatment processes according to the specific needs of customers, meeting the diverse demands of different industries and application scenarios.

Three. Characteristics of semi-cross lapped spunlaced nonwoven fabric

High surface uniformity: Through precise equipment control and process optimization during the carding and web formation and spunlacing processes, the semi-cross lapped spunlaced nonwoven fabric has uniform weight and consistent thickness, with no obvious defects or color differences, and a clean and beautiful appearance.

Good environmental friendliness: The company prioritizes the use of environmentally friendly fiber raw materials and does not use adhesives or other chemical substances during the production process, avoiding potential harm to the environment and human health. After disposal, some types (such as pure natural fiber products) can be naturally degraded, meeting environmental protection requirements and aligning with the green development trend.

Good washability: Through special process treatment, the semi-cross lapped spunlaced nonwoven fabric has good washability. After multiple washes, it can still maintain good structural stability and performance indicators, without deformation or pilling, and can be reused.

Strong processing adaptability: The product has good processing properties such as cutting, sewing, and printing, and can be processed in various forms according to actual application needs, facilitating the production of various different forms of products and providing convenience for downstream customers' production and processing.

Four. Weight range of semi-cross lapped spunlaced nonwoven fabric

The semi-cross lapped spunlaced nonwoven fabric produced by Changshu Yongdeli Spunlaced Nonwoven Fabric Co., Ltd. has a wide weight range, meeting the diverse needs of different customers. The weight range is 25g/㎡ - 120g/㎡.

Low weight products (25g/㎡ - 50g/㎡): Light and thin, with excellent breathability, mainly used in the surface layer of baby diapers, the inner layer of medical protective masks, and other scenarios where product thickness and weight are strictly limited.

Medium weight products (51g/㎡ - 80g/㎡): Combining lightness and certain strength, with excellent comprehensive performance, widely used in wet wipes, cosmetic pads, medical dressings, disposable bed sheets, and other fields.
