Reshaping and application expansion of spunlace nonwoven fabrics through sizing treatment

In the textile industry, sizing treatment, as an important finishing technology, is widely used in the production process of various types of non-woven fabrics, especially spunlace non-woven fabrics. Sizing, as the name suggests, is to coat one or more layers of slurry on the surface of fiber materials to enhance, protect or impart new functions. For spunlaced non-woven fabrics, this treatment not only changes their physical properties, but also brings significant changes in touch, especially an increase in stiffness.

Reshaping of touch by sizing treatment
Spunlaced non-woven fabrics that have not been sized are known for their natural and soft touch. The fibers are entangled with each other through the impact of high-pressure water flow, forming a unique network structure. However, this natural softness may not be ideal in certain application scenarios. For example, in products that require a certain amount of support or shape retention, such as medical bandages, industrial filtration materials, or certain home furnishings, a soft touch may cause the material to deform and become difficult to fix.

Sizing treatment was born as a solution to this need. The selection and formula design of the sizing can accurately control the effect of sizing, which not only retains the original excellent properties of spunlace non-woven fabrics such as air permeability and water absorption, but also forms a thin layer through the adhesion of the slurry to the fiber surface. Thin, almost transparent protective film. This film not only enhances the bonding force between fibers, but also significantly improves the stiffness and wrinkle resistance of the material. Therefore, the spunlaced non-woven fabric after sizing is stiffer to the touch, but does not lose its unique softness and skin-friendliness, achieving a perfect balance between touch and functionality.

Meet the needs of specific application scenarios
Sizing treatment reshapes the feel of spunlaced non-woven fabrics, making them more suitable for diverse market needs. In the medical field, stiff yet soft spunlace non-woven fabrics are widely used in the production of bandages, dressings and other products. They can not only effectively support wounds, but also reduce friction and irritation to the patient's skin, improving comfort. . In the industrial field, high-stiffness spunlace non-woven fabrics are ideal for filter materials, wipers and other products. Their excellent shape retention and wear resistance ensure the long-term stability and efficiency of the product.

In addition, with the improvement of environmental awareness, more and more sizing materials are beginning to use natural degradable materials, such as starch, cellulose, etc., which not only reduces environmental pollution during the production process, but also makes sizing spunlace non-woven fabrics It is easier to be naturally degraded after being discarded, which is in line with the concept of sustainable development.

Sizing treatment opens new doors for its application in more fields by changing the feel of spunlace nonwovens. This tactile reshaping not only meets the needs of specific application scenarios, but also reflects the textile industry's keen insight into technological innovation and market demand. With the continuous advancement of science and technology and the increasingly diversified consumer demands, sized spunlace non-woven fabrics will surely exert their unique advantages in a wider range of fields.
