Problems solved by technology

Because of its low cost, high output, and good water absorption, it is widely used in the field of facial masks. However, the fiber fineness that the carding process can adapt to is limited, and a single ultra-fine fiber is not suitable for carding production lines. Therefore, there is no ultra-fine fiber in traditional mask substrates. place for fiber

Embodiment Construction

[0030] An embodiment of the present invention will be further described in conjunction with the accompanying drawings.

[0031] The present invention is obtained by using PET-PA6 two-component hollow segmented orange spunbond spunlace cloth, after alkali (NaOH) decrement treatment, dissolving all or part of PET, and achieving complete fiber opening effect.

[0032] The two-component hollow orange segment spunbond spunlace nonwoven fabric process refers to drying and melting PET and PA6 materials, and extruding the two components through the spinneret hole in a certain arrangement and ratio through a special spinning assembly. thus forming as Figure 4 The special fiber cross-section is drawn, and then the web is drawn, and then reinforced by high-pressure water needles and initially opened to form a non-woven fabric. The two-component hollow pie-shaped spunbond spunlace nonwoven fabric process is generally used in the manufacture of leather base fabrics. It aims to obtain sup...

Abstract

The invention relates to a manufacturing method for an ultra-fine fiber long-fiber non-woven fabric. PET-PA6 double-component hollow orange section type spun-bonded spunlace cloth is subjected to alkali (NaOH) decrement aftertreatment, and all or part of PET is dissolved to achieve a complete splitting effect. By a filament laydown process, the product does not contain fiber broken ends, hooking to skin is relieved, touch feeling is improved, and sensitivity is reduced; and the fiber fineness of a mask base material is greatly improved, and the softness and skin fitting degree of the mask basematerial are qualitatively improved.

Description

technical field [0001] The invention relates to the field of long fiber nonwoven fabrics, in particular to a method for manufacturing ultrafine fiber long fiber nonwoven fabrics. Background technique [0002] Ultrafine fibers generally refer to fibers with a fiber fineness lower than 0.3D. This fineness is difficult to achieve directly by chemical spinning or solution spinning. Common ultrafine fibers are made by a two-component spinning process. A thick fiber short fiber, then laid net and strengthened into a cloth, and then dispersed to form a plurality of superfine fibers through the post-treatment process, mainly orange segment type (such as attached figure 2 shown) and island type (as attached image 3 shown) in two forms. [0003] Traditional non-woven mask substrates are generally made of viscose, polyester or lyocell staple fibers, which are made by carding and spunlace. Because of its low cost, high output, and good water absorption, it is widely used in the fiel...
