Abstract
The invention relates to the field of sanitary articles, and provides a pair of briefs type sanitary towel which accords with human engineering and a preparation method thereof, and solves the problems that the sanitary towel in the prior art is easy to have clamping legs and poor wrapping performance due to the defect of structural design.
Description
Technical Field
The invention relates to the field of sanitary products, in particular to a pair of briefs type sanitary towel conforming to human engineering and a preparation method thereof.
Background
Menstrual pants type sanitary napkins generally consist of an absorbent layer comprising a liquid permeable top layer, an absorbent core and a liquid impermeable bottom layer, which are laminated in this order from top to bottom. The outer clothing layer comprises an outer clothing layer, a spandex silk elastic material layer and an inner clothing layer which are sequentially laminated from outside to inside. The garment layer is divided into a front piece and a rear piece with the narrowest part of the garment layer (the narrowest part of the O-shaped ring) as a limit, and the front piece and the rear piece are respectively provided with a left end and a right end.
When a human body moves (walking, squatting, leg lifting and the like), because the legs move forwards and upwards, the upward pulling force is basically generated on trousers, so that the design of underpants and menstrual briefs is suitable for ergonomics, the principle that the front piece should be repaired without leg clamping, the rear piece can be covered by a triangle area and does not exceed the leg lifting line of the triangle area, so that the daily actions such as leg lifting, walking and the like are influenced, and the rear piece can be covered by the hip to the smile line of the buttocks as much as possible, so that the problems of absorber displacement and side leakage and back leakage are reduced.
Referring to fig. 1, the front and rear panels of the conventional panty-type sanitary napkin have the same width, and when the front and rear panels are worn after the front and rear panels are sealed, the seal line 1' is positioned at the left and right ends of the human body, and when a person moves, the front panel is pulled to the position behind the front panel, so-called "leg-clamping" is limited, and the rear panel cannot be wrapped forwards, so that the overall wrapping performance is poor.
Disclosure of Invention
Therefore, aiming at the problems, the invention provides the briefs type sanitary towel which accords with the ergonomics and the preparation method thereof, and solves the problems that the sanitary towel in the prior art is easy to have 'clamping legs' and poor wrapping performance due to the defect of structural design.
In order to achieve the above purpose, the present invention adopts the following technical scheme: the utility model provides a pair of briefs type sanitary towel according with human engineering, includes the absorber and sets up the garment thing layer outside the absorber, defines the absorber and has along longitudinal direction and along transverse direction, with crotch portion narrowest line as the boundary divide into front and back piece with the garment thing layer, the transverse width of back piece is greater than the transverse width of front piece, the fixed welding of the transverse both sides of front and back piece forms left seal line and right seal line, the transverse distance of left seal line and right seal line and human hip bump is 5-50mm, the longitudinal length of back piece is greater than the longitudinal length of front piece, the garment thing layer has the leg surrounding elastic material layer of setting in the leg surrounding department about, leg surrounding elastic material layer width is greater than or equal to 3mm.
Further: the absorbent is added with long fibers, and the long fibers are cotton fibers or fluff pulp fibers or viscose fibers or ES fibers.
Further: the angle of the back piece wrapping the human body is more than 195 degrees when the back piece is worn.
Further: the longitudinal dimension of the back panel is greater than the longitudinal dimension of the front panel by more than 10%.
Further: the absorber is formed by mixing fluff pulp, high molecular water-absorbing resin and long fibers.
Further: the fluff pulp: high molecular water-absorbing resin: weight ratio of long fibers = 10:1-3:0.5-2.
further: the outer layer non-woven fabric is provided with a pattern printing layer.
Further: the leg surrounding elastic material layer is composed of two groups of elastic materials, namely a first group of elastic materials and a second group of elastic materials, wherein the first group of elastic materials extends from the left upper region to the left middle region, then to the right middle region and finally to the right upper region of the front piece, and the second group of elastic materials extends from the left lower region to the left middle region, then to the right middle region and finally to the right lower region of the rear piece; or, the first group of elastic materials extends along the left upper region of the front sheet to the left middle region, then to the right middle region and finally to the right lower region of the rear sheet, and the second group of elastic materials extends from the right upper region of the front sheet to the right middle region, then to the left middle region and finally to the left lower region of the rear sheet; or, the first group of elastic materials extends along the left upper region of the front sheet to the left middle region, then extends to the left middle region of the rear sheet and finally extends to the left lower region of the rear sheet, and the second group of elastic material layers extends from the right upper region of the front sheet to the right middle region, then extends to the right middle region of the rear sheet and finally extends to the right lower region of the rear sheet;
the leg surrounding elastic material layer is any one or any combination of more than two of elastic spandex filaments, elastic non-woven fabrics and elastic films;
a preparation method of a pair of briefs type sanitary towel which accords with human engineering comprises the following preparation steps: (1) Preparation of an outer garment layer
s1, carrying out online transmission on the outer layer non-woven fabric, compounding an elastic spandex yarn and leg circumference elastic material layer online, and compounding the inner layer non-woven fabric to obtain a composite garment layer; the leg surrounding elastic material layer controls the transmission direction through the baffle plate, so that the leg surrounding elastic material layer is distributed between the outer layer non-woven fabric and the inner layer non-woven fabric in a specific shape;
s2, slitting a single outer clothing layer: slitting along the longitudinal direction to obtain single coat layers; the single garment layer has leg-surrounding O-rings, a narrower front panel and a wider back panel;
(2) Preparation of the absorbent body
a. Finishing long fibers: the long fibers are unpacked by a unpacking machine, coarsely unpacked by a coarse unpacking machine and combed to a single fiber state by a fine unpacking machine, and sent to an outlet of a wood pulp grinder by a quantitative fan to be mixed with fluff pulp and SAP;
b. mixing fluff pulp, high molecular water-absorbing resin and long fibers, and feeding into a mould wheel for forming;
c. attaching a wrapping layer to obtain an absorption core layer;
