Fiber material, preparation method and device and hygienic product

Abstract

The invention belongs to the field of special performance fiber products and composite materials, and particularly relates to a fiber material, a preparation method and device and a hygienic product. The composite fiber material can effectively solve the problems of poor three-dimensional retentivity, poor non-deformability, poor comfort, poor elasticity and the like in the existing single-layer or double-layer technology in the use process, and the fiber material forms support of an internal structure through upper / lower barb open holes and side barb open hole structures in a 3D bulge, so that the three-dimensional bulge is more compact in structure and more compact in structure. The three-dimensional sense, the elasticity and the non-deformability are improved, the contact area is further reduced, the air circulation performance is improved, the dryness, the air permeability, the comfort, the attractiveness and the experience feeling are improved, liquid back seepage is effectively reduced, the situation that thin excrement makes contact with and is attached to the skin is effectively reduced, and skin allergy is reduced.

Description

technical field [0001] The invention belongs to the field of special-performance fiber products and composite materials, and particularly relates to a non-woven fabric and a preparation method, device and application thereof. Background technique [0002] In the known technology, the single-layer textured perforated fiber product has a concave-convex bulge shape and a certain three-dimensional effect, but the single-layer textured perforated fiber product has the following defects and unsolved problems (such as figure 1 shown): [0003] A. The three-dimensional retention of single-layer textured fiber products is very poor, and the thickness and three-dimensional effect will be greatly reduced when they are made into roll materials; [0004] B. Especially when it is used to make diapers or sanitary napkins, the three-dimensional effect will be greatly reduced due to the stretching of the manufacturing process and the use of glue to bond to other materials; [0005] C. It w...

Problems solved by technology

[0015] The technical problem to be actually solved by the present invention is: the bulge on the conventional double-layer fiber fabric has poor deformation resistance, the structure is not easy to maintain, and the filler in the bulge in the three-layer composite material will cause poor permeability / breathability The problem

The invention provides a composite fiber material, which can effectively solve the problems of poor three-dimensional retention, poor deformation resistance, poor comfort, and poor elasticity in the existing single-layer or double-layer technology during use. , the fiber material forms the support of the internal structure through the upper / lower barb hole and the side barb hole structure in the 3D bulge, which increases the three-dimensional sense, elasticity and deformation resistance, and further reduces the contact area. Improve air circulation performance, increase dryness, breathability, comfort, aesthetics and experience, effectively reduce liquid rewet and effectively reduce loose stools contacting and adhering to the skin, and reduce skin allergies
