Full-cross spunlace non-woven fabric: perfect integration of craftsmanship and performance advantages – professional presentation from YDL Nonwovens

Spunlace technology: unlocking the flexible and powerful password of non-woven fabric

The spunlace process, also known as jet spraying into fabric, is based on the core principle of high-pressure micro water flow spraying onto the fiber net, causing the fibers to undergo displacement, interweaving, entanglement, and interlocking under hydraulic action, thereby achieving the reinforcement and shaping of the fiber mesh. Compared with traditional processes such as needle punching and spunbond, spunlace technology has irreplaceable advantages: firstly, it adopts a flexible entanglement method that does not damage the original characteristics of the fibers, and can preserve the softness and fluffiness of the fibers to the greatest extent possible, making the product closer to the touch of traditional textiles; Secondly, the production process does not require the addition of adhesives, which not only ensures the cleanliness and hygiene of the product, but also has excellent washability, especially suitable for scenarios where medical and hygiene products come into direct contact with the human body; Thirdly, precise control of water flow can achieve diverse appearance designs, while endowing the product with multiple characteristics such as high strength, low fuzziness, high moisture absorption, and good breathability.

Changshu Yongdeli Spunlace Non-woven Fabric Co., Ltd. is well versed in the essence of spunlace technology. From fiber metering and mixing, loosening and removing impurities, to mechanical combing into a net, to high-pressure water needle interlacing, drying and coiling, a strict quality control system has been established for each process. With precise control over key parameters such as water quality and pressure, the company's fully cross spunlace non-woven fabric achieves industry-leading levels in fiber entanglement uniformity and mechanical stability, perfectly demonstrating the technical charm of spunlace technology.

 

Full cross vs semi cross/parallel: the core advantage of performance compaction

The performance of spunlace non-woven fabric largely depends on the laying method. At present, the mainstream net lapping methods in the market include parallel, semi cross lapping, and full cross laying, which have significant differences in fiber arrangement, mechanical properties, and other aspects. Full cross lapping, with its unique "Z" - shaped layered lapping method, has formed a performance crushing effect on the other two methods. As a professional enterprise focusing on the production of fully cross lapping spunlace nonwoven fabric, Changshu Yongdeli spunlace nonwoven fabric Co., Ltd. has maximized the advantages of fully cross lapping through long-term practice.

 

Advantage 1: Strong balance in both machine direction and cross-machine direction, unlimited application scenarios

The parallel method uses fibers to overlap and lay the net along the machine direction. Although the production speed is high, the directional arrangement of fibers is extremely strong, resulting in a high machine direction and cross-machine direction tensile strength ratio of 3:1-5:1 for the product. When subjected to lateral force, it is prone to breakage, severely limiting its application in load-bearing, wiping and other scenarios. Although the semi cross laying network has improved the strength distribution through a parallel and a cross lapping combing machine, it is still limited by the number of layers and fiber interweaving density, and the aspect ratio of strength cannot reach the ideal equilibrium state, resulting in weak performance in high weight and high strength demand scenarios.

 

The fiber web output by the carding machine is layered in a "Z" shape by the cross lapping machine, achieving uniform distribution of fibers in both machine direction and cross-machine direction. The machine direction and cross-machine direction strength ratios are significantly reduced, while the cross-machine direction strength is significantly improved. The fully cross spunlace non-woven fabric produced by Changshu Yongdeli Spunlace Non woven Fabric Co., Ltd., with its balanced machine direction and cross-machine direction strength, can not only be applied to conventional scenarios such as dry wipes and wet wipes, but also meet the high requirements for strength and stability in fields such as mask fabrics and decorative composite materials. Even in high-intensity use scenarios such as industrial wiping, it can maintain excellent wear resistance and durability, completely solving the application limitations of parallel and semi cross products.

 

Advantage 2: Strong compatibility between thickness and weight, superior texture

Parallel lapping and semi cross lapping net are limited by the net structure, and are prone to problems such as thin middle and thick edges when producing high weight products. In addition, the uniformity of product thickness is poor, and the hand feel is thin and hard. The fully cross lapping net is naturally suitable for the production of high weight products. Through multi-layer "Z" - shaped stacking, flexible adjustment of 60g-260g or even higher weight can be achieved. With the support of a complex control system, the cross-sectional profile of the fiber net can be effectively corrected to ensure uniform and consistent product thickness.

Changshu Yongdeli Spunlace Non-woven Fabric Co., Ltd. relies on advanced fully cross lapping net equipment to produce products that not only have excellent thickness uniformity, but also have a more fluffy and soft feel due to higher fiber interweaving density. Compared with the "thin and easy to deform" of the parallel product and the "hard texture" of the semi cross product, the company's full cross spunlace non-woven fabric can bring a more comfortable use experience in the scenes of baby care, beauty facial mask and other scenes with high touch requirements, which is also one of the core reasons why many high-end health products enterprises choose to cooperate with Yongdeli.

 

Advantage 3: Balancing water absorption and durability, with more outstanding cost-effectiveness

Core application scenarios such as wiping and hygiene have dual requirements for the water absorption and durability of non-woven fabrics. Parallel products are prone to fiber shedding and structural damage after absorbing water due to loose fiber entanglement; Although semi cross products have slightly improved durability, they are still limited by the degree of fiber interweaving, resulting in insufficient water absorption rate and retention capacity. The fully cross lapping is formed by tightly interweaving multiple layers of fibers, creating a rich internal pore structure that not only ensures rapid water absorption performance, but also maintains structural stability after water absorption, making it less prone to deformation and pilling.

 

Changshu Yongdeli Spunlace Non-woven Fabric Co., Ltd. has optimized the fiber ratio and the number of net layers to increase the water absorption rate of the fully crossed spunlace non-woven fabric by more than 30% compared to the same weight parallel product, and to increase the water retention by 20%. At the same time, the amount of fiber shedding during repeated wiping is much lower than the industry standard. In the home cleaning scene, using Yongdeli's fully cross-lapping spunlace non-woven fabric to make cleaning cloths can reduce tool carrying capacity by 60% and improve cleaning efficiency by 45%; In outdoor scenarios such as camping, its fast drying characteristics and durability can better meet the needs of lightweight and convenient use, fully reflecting the product advantages of "high performance + high cost-effectiveness".
