Application Of Fine Spunlace Nonwoven Fiber
Fine fiber refers to the diameter coefficient of the fiber. This coefficient is represented by the letter "D" - also known as "denier" or (denier: Denier).
The smaller the "D" number, the smaller the diameter of the representative fiber, that is, the thinner, and vice versa. For example, 1.4D Tencel and 3.2D PET fiber, 1.4D is smaller than 3.2D, and the fiber is fine and soft. The smaller the Denier coefficient, the better the performance of the fiber after the cloth is formed, and even with the obvious skin adsorption.
At present, the most common fiber denier in the spunlace nonwoven industry worldwide is 1.3~1.7D. Such as copper ammonia fiber, Tencel, viscose and so on. The finest fiber is only 0.45D, which is derived from the ultrafine fiber of Mitsubishi Rayon co.,Ltd. Domestic production of the finest fiber has reached 0.6D, compared with Japanese production technology, there is still a large technical difference. The smaller the fiber, the difficulty in making the fiber or the difficulty in processing the spunlace into a cloth.
At present, Prius has mastered certain techniques for the processing of ultrafine fiber spunlace. The weight of spunlace made of 100% ultrafine fiber ranges from 38 to 80 g/m2, and the maximum effective width. It is 200CM.
