Problems solved by technology

However, when making disposable absorbent products, the edge parts on both sides of the non-woven fabric surface layer need to be bonded with water-repellent flanks or three-dimensional guards to prevent side leakage. Sticky non-woven fabric or water-repellent hot-air non-woven fabric, so when bonding, if the surface layer of the surface layer non-woven fabric contains cotton fibers, due to the difference in surface tension, the product qualification rate caused by poor bonding may occur drop, or skin allergies caused by excessive use of hot melt adhesive

Embodiment 2

[0043] Such as Figure 2a , Figure 2b As shown, the cotton fiber with a content of 100% is carded by a carding machine, and the net is laid on the bottom non-woven fabric C2, and then the excess content outside the strip-type spacer 25 covered on the surface fiber web B2 is passed through the blower fan 1. Cotton fibers are sucked out so that the surface layer fiber web B2 forms several surface layer fiber webs 2a that are continuous strips in the transverse direction, and then the strip-type surface layer fiber webs 2a and the bottom non-woven fabric C2 are treated by spunlace. Under the double action of spunlace impact force and reflection force, random movement, interpenetration, entanglement, and cohesion occur between fibers, forming countless soft entanglement points, and consolidating the strip-like surface fiber web 2a on the bottom layer. On the woven fabric C2, the non-woven fabric after the spunlace treatment is finally dried, cut, rolled and other steps to form a p...

Embodiment 3

[0046] Such as Figure 3a , Figure 3b As shown, the cotton fiber with a content of 75% and the PE / PP short fiber with a content of 25% are carded by a carding machine, laid on the bottom non-woven fabric C3, and then the strip covered on the surface fiber web B3 is passed through the fan 1 The superfluous cotton-containing fiber outside the type spacer 35 is sucked out to make its surface layer fiber web B3 form several strip-type surface layer fiber webs 3a in the longitudinal and transverse directions, and then the strip-type surface layer fiber web 3a and the bottom layer After the non-woven fabric C3 is processed by the spunlace process, under the double action of the spunlace impact force and the reflection force, the fibers move, intersperse, entangle, and cohere randomly, forming countless soft entanglement points, and the strips The superficial fiber web 3a of the formula is consolidated on the bottom non-woven fabric C3, and finally the non-woven fabric after spunla...

Embodiment 4

[0049] Such as Figure 4a , Figure 4b As shown, the hydrophobic cotton fibers with a content of 50% and the hydrophobic PE / PET short fibers with a content of 50% are carded through a carding machine, laid on the bottom non-woven fabric C4, and then covered on the surface fiber web B4 by fan 1. The superfluous cotton-containing fibers outside the strip-type spacer 45 are sucked out to make its surface layer fiber web B4 form several strip-type surface layer fiber webs 4a in the longitudinal and transverse directions, and then the strip-type surface layer fiber webs 4a And the bottom non-woven fabric C4 is processed by the spunlace process. Under the double action of spunlace impact force and reflection force, the fibers move, intersperse, entangle, and cohere randomly, forming countless soft entanglement points. The strip-type surface layer fiber web 4a is consolidated on the bottom non-woven fabric C4, and finally the non-woven fabric after spunlace treatment is dried, cut, ...

Abstract

The invention relates to a non-woven fabric with the local part containing cotton and a production method of the non-woven fabric. The non-woven fabric with the local part containing the cotton comprises a surface-layer fiber web and a bottom-layer non-woven fabric, the surface-layer fiber web is shaped like a strip, entanglement points formed by the surface-layer fiber web through fiber interspersing and entangling are fixedly bonded on the bottom-layer non-woven fabric, and fibers of the surface-layer fiber web are composed of 50%-100% of cotton fibers. Due to the fact that only the surface-layer local area makes contact with the skin when the non-woven fabric is used as a surface layer of an absorption product, the non-woven fabric with the local part containing the cotton not only fully utilizes the skin-friendly and safe characteristics of a surface-layer fiber layer composed of natural fibers, but also can decrease the using amount of the surface-layer cotton fibers on the basis that the skin friendliness is guaranteed, and then the purpose of reducing the production cost is achieved; meanwhile, the non-woven fabric with the local part containing the cotton can effectively solve the problem that the surface layer cannot be firmly bonded with side wings or a three-dimensional protective enclosure.

Description

technical field [0001] The present invention relates to a non-woven fabric and its production method, more particularly to a non-woven fabric which can be used for the surface of a disposable absorbent product partially containing cotton fibers and its production method. [0002] technical background [0003] In disposable absorbent products, such as diapers for infants, diapers, sanitary napkins for women, sanitary pads for maternity, incontinence products for adults, etc., non-woven fabrics as surface materials have become an indispensable and important component of absorbent products. Not only because of its direct contact with human skin, but also plays a key role in directing liquid to the absorbent core. Therefore, while having good liquid permeability, ensuring the comfort and dryness of the skin in the use environment is a common requirement for the surface layer of non-woven fabrics. [0004] Because the traditional non-woven surface layer based on chemical syntheti...
