Embodiment 1

[0045] The mass fraction of each component in the first cotton core layer is as follows: wood pulp fiber accounts for 30 parts, and polymer water-absorbent resin accounts for 70 parts.

[0046] The mass fraction of each component in the second cotton core layer is as follows: wood pulp fiber accounts for 10 parts, bamboo fiber accounts for 20 parts, and polymer water-absorbing resin accounts for 70 parts.

[0047] The preparation process is as follows:

[0048] 1) Crush

[0049] Take 30 parts of wood pulp fiber and 70 parts of polymer water-absorbing resin and place it in a pulverizer to pulverize, so that the length of the pulverized wood pulp fiber is 2-2.8 mm, and after pulverization, mix evenly, and transport it into the forming drum to obtain the first cotton core Layer mixed powder;

[0050] Similarly, take 10 parts of wood pulp fibers, 20 parts of bamboo fibers, and 70 parts of polymer water-absorbing resin and place them in a pulverizer for pulverization, so that the...

Embodiment 2

[0056] The mass fraction of each component in the first cotton core layer is as follows: wood pulp fiber accounts for 70 parts, and polymer water-absorbent resin accounts for 30 parts.

[0057] The mass fraction of each component in the second cotton core layer is as follows: wood pulp fiber accounts for 40 parts, bamboo fiber accounts for 30 parts, and polymer water-absorbing resin accounts for 30 parts.

[0058] The preparation process is as follows:

[0059] According to each component and content ratio in this example, place it in a pulverizer and pulverize to obtain the first cotton core layer mixed powder and the second cotton core layer mixed powder; the rest of the process steps of forming and embossing refer to the examples 1 is carried out, and finally the finished cotton wick is obtained.

Embodiment 3

[0061] The mass fraction of each component in the first cotton core layer is as follows: wood pulp fiber accounts for 40 parts, and polymer water-absorbent resin accounts for 60 parts.

[0062] The mass fraction of each component in the second cotton core layer is as follows: wood pulp fiber accounts for 20 parts, bamboo fiber accounts for 20 parts, and polymer water-absorbing resin accounts for 60 parts.

[0063] The preparation process is as follows:

[0064] According to each component and content ratio in this example, place it in a pulverizer and pulverize to obtain the first cotton core layer mixed powder and the second cotton core layer mixed powder; the rest of the process steps of forming and embossing refer to the examples 1 is carried out, and finally the finished cotton wick is obtained.

Abstract

The invention discloses a cotton core used in an adult diaper. The cotton core used in the adult diaper comprises a bridge-shaped first cotton core layer and an oval second cotton core layer, wherein the second cotton core layer is arranged in the middle of the first cotton core layer. The cotton core is characterized in that embossed patterns cover the surface of the first cotton core layer and the surface of the second cotton core layer; the first cotton core layer comprises wood pulp fiber and high-molecular water-absorbing resin; the second cotton core layer comprises wood pulp fiber, bamboo fiber and high-molecular water-absorbing resin. The cotton core used in the adult diaper is formed by compounding a variety of fiber, and the structural design of an outer honeycomb and inner linear shape, so that the cotton core is strong in absorption capacity, good in diffusion ability and even in stress, the defects of clustering, delaminating, cracking and the like caused by water swelling are overcome, and the comfort level of users is improved. A manufacturing method of the cotton core is simple in process and high in operation efficiency, and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a textile material prepared by mixing wood pulp fiber and bamboo fiber, which is mainly applied to adult urinary incontinence care products as the core absorption layer of adult diapers and other care products. Background technique [0002] According to statistics, as of the end of 2012, my country's population aged 60 and above reached 193.9 million, accounting for 14.3% of the total population, and most of the elderly are plagued by incontinence problems. will increase accordingly. As a necessity for patients, incontinence products have attracted more and more attention in recent years. [0003] There are many examples of research and development and successful application in China in recent years. At present, most of the diapers on the market have a bridge-like structure with two wide ends and a narrow middle. Usually, the absorbent layer is formed by mixing fluff pulp and a polymer water-absorbing layer, and then passing th...
