1. The impact of fiber gaps on feel
The feel of spunlace nonwoven fabric is one of the important indicators for its quality evaluation. The size of the fiber gap is directly related to the smoothness and softness of the surface of the spunlace non-woven fabric.
Moderate fiber gap: When the fiber gap is moderate, the fibers are arranged closely and orderly, forming a uniform and delicate touch. This spunlace non-woven fabric not only feels soft, but also has good fluffiness, giving people a comfortable and warm feeling.
The fiber gap is too small: If the fiber gap is too small, the fibers will be packed too tightly, causing the surface of the spunlaced non-woven fabric to become smoother and lack softness. In addition, too small fiber gaps may also affect the breathability of spunlace non-woven fabrics, causing them to feel stuffy during use.
Excessive fiber gap: When the fiber gap is too large, the arrangement between fibers will become sparse, causing the surface of the spunlaced non-woven fabric to become rough. This kind of spunlace non-woven fabric has a poor hand feel and can easily give people an uncomfortable feeling.
2. Effect of fiber gaps on strength
In addition to the feel, the strength of spunlace non-woven fabrics is also one of the important indicators for quality evaluation. The size of the fiber gap directly affects the tensile strength and tear strength of the spunlace non-woven fabric.
Moderate fiber gaps: Appropriate fiber gaps can make spunlace non-woven fabrics have a certain tensile strength and tear strength. This is because the fibers are arranged closely and orderly, forming a certain interwoven structure, thereby improving the strength of the spunlace non-woven fabric. This kind of spunlace non-woven fabric can maintain good stability and durability when subjected to external forces.
The fiber gap is too small: If the fiber gap is too small, the fibers will be packed too tightly, resulting in a reduction in the tensile strength and tear strength of the spunlaced non-woven fabric. This is because too small fiber gaps limit the relative movement between fibers, making the spunlace non-woven fabric prone to breakage or damage when subjected to external forces.
Excessive fiber gaps: Although excessive fiber gaps can improve the softness of spunlace non-woven fabrics, they can also reduce their strength and durability. Because the arrangement between fibers is too sparse, it is impossible to form a sufficient interwoven structure to support the strength of spunlace non-woven fabrics. This spunlace non-woven fabric is prone to deformation and damage when subjected to external forces.
Therefore, when producing spunlaced non-woven fabrics, it is necessary to control the size of the fiber gaps to balance the relationship between feel and strength. By optimizing the production process and parameter settings, spunlace nonwoven products with ideal feel and strength can be obtained. At the same time, with the continuous development of spunlace composite technology, the fiber gap control of spunlace non-woven fabrics will be more precise and efficient in the future, further improving its performance and application value.
