Embodiment 1

[0026] This example provides a method for manufacturing a matrix carrying a superabsorbent resin, including the following steps, the flow chart of which is as follows: figure 1 shown.

[0027] S1: Feed cotton.

[0028] In this step, polyester low-melting-point staple fibers and polyester staple fibers are respectively supplied, wherein the deniers of the polyester low-melting-point staple fibers are 1D-10D, and the deniers of the polyester staple fibers are 1D-10D, and specific deniers can be selected according to actual applications.

[0029] S2: loosen.

[0030] In this step, the polyester low-melting-point staple fiber and the polyester staple fiber are respectively opened by an opener, and the purpose is to loosen the compacted and entangled polyester low-melting-point staple fiber and the polyester staple fiber respectively.

[0031] S3: Cotton blend.

[0032] Fully mix the polyester low-melting-point staple fiber and polyester staple fiber loosened in step S2, and the...

Embodiment 2

[0040] Such as image 3 As shown, the difference between this example and Example 1 mainly lies in that the hot air process in this example adopts the flat screen hot air production process, and correspondingly, the dryer in this example is a flat screen dryer 10 .

[0041] Concretely, polyester low melting point staple fiber and polyester staple fiber are proportioned according to the ratio of 50%:50%. Two cotton feeders 2; the first cotton feeder 1 feeds the polyester low-melting point staple fibers into the first opener 3, and the first opener 3 opens the polyester low-melting point staple fibers for the purpose of compressing, Intertwined polyester low-melting-point staple fibers are loosened; similarly, the second cotton feeder 2 feeds the polyester staple fibers into the second opener 4, and the second opener 4 opens the polyester staple fibers; The decomposed low-melting point staple fiber and polyester staple fiber are transported to the cotton blender 5 and fully mix...

Embodiment 3

[0043] Based on Embodiment 1 and Embodiment 2, this example provides a water-absorbent core for disposable sanitary products, such as Figure 4 As shown, the water-absorbent core includes a super-absorbent resin 101 and a base 102 , and the base 102 is used to accept the super-absorbent resin 101 .

[0044] The matrix 102 of this example is basically made up of polyester low melting point staple fiber and polyester staple fiber, and polyester low melting point staple fiber and polyester staple fiber are mixed with the ratio of 10%~90%:90%~10%, the ratio of this example is preferably 50%:50%, wherein, the polyester staple fiber is a three-dimensional crimped hollow staple fiber.

[0045]In addition, in this example, the manufacturing method of the base body 102 may adopt the manufacturing method of the first embodiment or the second embodiment. For details, please refer to the first and second embodiments, which will not be repeated in this example.

[0046] Because the matrix...

Abstract

The invention discloses a manufacturing method of basal body bearing super absorbent resin. The method comprises the following steps: supplying cotton: respectively supplying terylene low-melting-point short fiber and terylene short fiber; opening: respectively debonding terylene low-melting-point short fiber and terylene short fiber; mixing cotton: mixing the terylene low-melting-point short fiber and terylene short fiber into the base material, the ratio is 10-90%: 90-10%; combing into web: combing the base material through a combing machine and processing the material into the fibre web; hot sticking the fibre web: transferring the fibre web to a drying machine, adopting hot wind technology for executing hot sticking process on the fibre web for forming the basal body with 100% terylene material. The basal body prepared by the basal body manufacturing method is 100% terylene material, compared with the basal body comprising ES short fiber material, the space of the basal body prepared by the method is big, the super absorbent resin can be evenly distributed on the basal body for forming water absorption core body, thus the liquid through performance of the water absorption core body is improved, the basal body is made of 100% terylene material, so that the basal body can be recycled for 100% and the green environment protection performance is further improved.

Description

technical field [0001] The invention relates to the field of disposable hygienic products, in particular to a method for making a substrate for superabsorbent resin, a water-absorbing core based on the substrate, and a disposable hygienic product made from the water-absorbing core. Background technique [0002] Now people use a lot of disposable sanitary products in their daily life, such as diapers, sanitary napkins, adult pads, etc., and their function is to absorb liquids such as urine, and the amount of liquid absorption is what people measure these An important indicator of disposable hygiene products. [0003] Disposable sanitary products include a water-absorbent core, which is composed of a super absorbent resin (SAP) and a matrix for receiving the super absorbent resin. At present, the matrix is ​​made of ES short fibers and polyester fibers bonded by hot air The ratio of the two is: ES staple fiber 85-90%, polyester fiber 10-15%. However, due to the dense fiber s...
