Problems solved by technology

It can be seen that it is difficult to produce a 30 g/m 2 The following products are difficult to meet the requirements of lightness, thinness and transparency
Some people also try to lightly roll the spun fiber web, and then compound it with the carded fiber web to reduce the influence of the bonding point of the spun fiber web, but there is no mature process plan that can be used to guide production
Because it is difficult to adjust only the hot rolling process without the cooperation of fiber modification and spunlace process, and without complete theoretical guidance
Either because the bonding poin...

preparation example Construction

[0050] The preparation of false bonded spunbonded fiber web 2 is one of key points of the present invention, and false bonded spunbonded fiber web 2 refers to that when the bonding point 1 of the spunbonded fiber web is subjected to tensile force or impact force, the bonded Point 1 can be disassembled without fiber breakage. That is to say, the bonding force produced by the bonding point 1 to the fiber is smaller than the strength of the fiber itself. The main point of preparing the fiber web is that when the spun fiber web is hot-rolled, low-temperature and low-pressure hot-rolling is adopted, so that the fibers at the rolling point are not completely melted. Specifically, for polyester fiber webs, the hot-rolling temperature should be controlled at 180-200°C; for nylon fiber webs, the hot-rolling temperature should be controlled at 160-180°C; for polypropylene fiber webs, the hot-rolling temperature should be controlled at 80~110℃, the hot rolling pressure is 1 / 3~3 / 4 of the...

Embodiment 1

[0076] Firstly, 0.5% of the total weight of the polyester modulus-reducing masterbatch is evenly added to the polyester spinning chip, and then the screw spinning machine is heated, mixed, metered, and spun, and the surface of the polyester fiber filament is evenly attached to the hydrophilic by impregnation. The hydrophilic agent is a polyester or polyether compound solvent containing a hydrophilic group, and then stretched, separated, and laid to form a polyester spun fiber web, and the weight is controlled at 12 grams / m 2 . Then carry out low-temperature, low-pressure hot-rolling bonding to the spun fiber web, and the hot-rolling temperature should be controlled at 180° C.; the hot-rolling pressure is 0.9 MPa of conventional hot-rolling pressure. Simultaneously lay a carded fiber web 2 online, the composition is 80% viscose staple fiber, 10% chitosan fiber and 10% mint fiber, the specification is 1.5 denier × 51mm, and the gram weight is 20 g / m 2 , using cross-stacking. S...

Embodiment 2

[0078] First, 0.5% of the total weight of the polyester modulus-reducing masterbatch is evenly added to the polyester spinning chips. Then, it is heated, mixed, metered, and spun by a screw spinning machine, and the surface of the polyester fiber filament is evenly adhered to a hydrophilic agent by dipping. The hydrophilic agent is a polyester or polyether compound solvent containing a hydrophilic group, and then Stretching, splitting, and laying to form a polyester spinning fiber web, the weight is controlled at 15 grams / m 2 . Then carry out low-temperature, low-pressure hot-rolling bonding to the spun fiber web, and the hot-rolling temperature should be controlled at 200° C.; the hot-rolling pressure is 0.9 MPa of conventional hot-rolling pressure. Simultaneously lay a carded fiber web 2 online, the composition is 80% viscose staple fiber, 10% chitosan fiber and 10% mint fiber, the specification is 1.5 denier × 51mm, and the gram weight is 18 g / m 2 , using cross-stacking, ...

Abstract

The invention discloses a health dry and comfortable sanitary towel with an antisepsis, ventilating cool and refreshing surface. The health dry and comfortable sanitary towel is composed of a surface layer clinging to the skin, an adoption layer disposed under the surface layer, a ventilating leakproof film arranged at the outermost, and back glue used for fixing the sanitary towel. The surface layer comprises a waterpower entanglement integrated non-woven base cloth which is formed by that a fake bonding spun-bonded fibrous reticulum and a carding fibrous reticulum are reinforced through spunlace on line or off line, the carding fibrous reticulum is carded by hydrophilic short chitosan fiber and mint fiber, the fake bonding spun-bonded fibrous reticulum is spun by thermoplastic fiber filament which is subjected to softening modulus treatment and hydrophilic treatment, the carded fiber layer clings to the skin, and the fake bonding spun-bonded fibrous reticulum combines with the adoption layer. 2 to 5 layers of carding fibrous reticulum (3) and a fake bonding spun-bonded fibrous reticulum (2) are reinforced through spunlace, the problems that a conventional multi-layer sanitary towel is over thick and poor in ventilation can be solved.

Description

technical field [0001] The invention belongs to the technical field of sanitary products, and in particular relates to a dry protective pad with high antibacterial, breathable and cool health functions on the body surface. Background technique [0002] When female compatriots have sanitary napkins to make menstruation less embarrassing, people invented pads similar to sanitary napkins. It can absorb the daily secretions of women outside the menstrual period, which greatly relieves women's troubles. Pads are generally smaller and thinner so that there is no discomfort and are a useful invention. Existing sanitary pads generally include a hydrophilic layer, a diversion layer, a mixed layer of dust-free paper and water-absorbing polymer, a waterproof bottom film and a release paper. The hydrophilic layer is located on the upper surface, and the diversion layer is located on the hydrophilic layer. Underneath and above the mixed layer of dust-free paper and water-absorbing po...
