Problems solved by technology

Most of the current surface layer materials are single fiber, single-layer fiber net, the liquid transfers up and down, and the penetration is fast, often with a large amount of re-seepage, and the penetration speed is slow, which cannot meet the needs of rapid penetration of sanitary products, and the fluffy softness is not enough. Control The finished product has poor rewetting effect, resulting in a high allergy rate of sanitary products

Embodiment Construction

[0012] The ultra-dry surface layer material is composed of two layers of fiber webs. The upper and lower fiber webs are carded independently, and the double fiber webs are stacked up and down, and then the double fiber webs are reinforced by a hot air oven.

[0013] The upper fiber web adopts sheath-core bicomponent fibers, in which the cortex is polyethylene, the core is polyester, the fiber length is 38 or 51mm, the fiber fineness is 1.5-3D, and the number of fiber crimps is 12-19 / 25mm. The crimp rate is 13-21%, and the fiber has been treated with strong hydrophilic oil agent HA-YJ-1309D / HA-YJ-1308 (commercially available) several times (oil rate 0.3-0.6%). The fiber enters the carding machine after being opened and cleaned by the bale opener, and is transferred to the doffer after being carded by the cylinder. By adjusting the speed ratio between the work roll and the large cylinder, most of the fibers after carding are arranged regularly along the length direction.

Abstract

The invention discloses a super dry and clean face layer material. The face layer material is fastened by two layers of fiber nets through hot air, the upper layer fiber net and the lower layer fibernet are both made of leather core double-component fiber, but hydrophilic finishing agents, the oiling rates, the fiber thicknesses, the fiber rolling numbers and the fiber rolling rates of the upperlayer fiber net and the lower layer fiber net are all different, the two layers of fiber nets are carded through a twin-carding machine respectively and are lapped, and the material is attached and fixed through a hot air drying box. The super dry and clean face layer material has the advantage that multiple times of quick permeating are conducted, liquid permeates downwards at a single point, theupper layer expanding area is small, and the permeating-back amount is small.

Description

technical field [0001] The invention relates to an ultra-dry surface layer material. The super-dry surface layer material is mainly used as the surface layer of disposable sanitary products such as paper diapers and sanitary napkins. Background technique [0002] The surface layer material is located on the surface layer of disposable sanitary products (such as paper diapers, sanitary napkins, etc.), and mainly plays the role of contacting with the skin, receiving liquid, conducting liquid, rapid infiltration and preventing back seepage. Tactile, and when the liquid reaches the layer, it is required to be transferred to the absorbent core layer quickly and with as little adhesion as possible, shorten the contact time between the liquid and the skin, reduce the amount of contact between the liquid and the skin, and effectively reduce the occurrence of hygienic product allergies. [0003] The surface layer used in the existing disposable sanitary products is mainly hot-air no...
