Problems solved by technology

[0003] However, most of the existing non-woven fabrics are made of synthetic fibers. Synthetic fibers have poor hygroscopicity. Long-term use is likely to cause symptoms such as skin itching and red buttocks in infants and young children. Moreover, the surface of non-woven fabrics has poor softness and rough surface. , direct contact with the delicate skin of infants will cause friction, which will easily cause damage to the skin of infants, cause discomfort in infants, and even cause skin allergies in infants; in addition, because diapers absorb infant urine, it is easy to breed bacteria, Diapers are in direct contact with the reproductive system of infants, which makes the reproductive system of infants particularly vulnerable to bacterial invasion and infection.

Embodiment 1

[0034] A pure silk diaper, such as figure 1 and figure 2 As shown, it includes a surface layer 2, a moisture-absorbing layer 4 and a bottom layer 8 from top to bottom. The inner surface of the surface layer 2 is attached with an inner surface contact layer 1. The inner surface contact layer 1 is a silk layer, and the silk layer is woven from natural silk fibers. The surface layer 2 is made of 30% natural silk fiber and 70% plant fiber by mass percentage, and the plant fiber is a mixture of hemp fiber, cotton linter fiber and bamboo charcoal fiber, and in the plant fiber, hemp fiber, cotton linter fiber and The mass ratio of bamboo charcoal fiber is 1:5:1, and the bottom layer 8 is a thermoplastic synthetic resin film impermeable to liquid.

[0035] Among them, such as image 3 and Figure 4 As shown, the hygroscopic layer 4 includes a first hygroscopic layer 5 and a second hygroscopic layer 6 arranged sequentially from top to bottom, the first hygroscopic layer 5 is provid...

Embodiment 2

[0044] A pure silk diaper, comprising a surface layer 2, a moisture-absorbing layer 4 and a bottom layer 8 from top to bottom, an inner surface contact layer 1 is attached to the inner surface of the surface layer 2, and the inner surface contact layer 1 is a silk layer, and the silk layer is composed of Natural silk fiber is woven, and the surface layer 2 is made of 60% natural silk fiber and 40% plant fiber by mass percentage, and the plant fiber is a mixture of hemp fiber, cotton linter fiber and bamboo charcoal fiber, and the hemp fiber in the plant fiber 1. The mass ratio of cotton linter fiber and bamboo charcoal fiber is 3:4:1.5, and the bottom layer 8 is a thermoplastic synthetic resin film impermeable to liquid.

[0045] Among them, the hygroscopic layer 4 includes a first hygroscopic layer 5 and a second hygroscopic layer 6 arranged sequentially from top to bottom, the first hygroscopic layer 5 is provided with a flexible water-absorbing block, and the second hygrosco...

Embodiment 3

[0054] A pure silk diaper, comprising a surface layer 2, a moisture-absorbing layer 4 and a bottom layer 8 from top to bottom, an inner surface contact layer 1 is attached to the inner surface of the surface layer 2, and the inner surface contact layer 1 is a silk layer, and the silk layer is composed of Natural silk fiber is woven, and the surface layer 2 is made of 45% natural silk fiber and 55% plant fiber by mass percentage, and the plant fiber is a mixture of hemp fiber, cotton linter fiber and bamboo charcoal fiber, and the hemp fiber in the plant fiber 1. The mass ratio of cotton linter fiber and bamboo charcoal fiber is 2:6:2, and the bottom layer 8 is a thermoplastic synthetic resin film impermeable to liquid. Such as Figure 5 and Figure 6 As shown, a breathable anti-seepage layer 7 is also arranged between the hygroscopic layer 4 and the bottom layer 8. The breathable anti-seepage layer 7 is a layer of PET perforated film, and the side of the PET perforated film i...

Abstract

The invention discloses a pure silk diaper which sequentially comprises a surface layer, a moisture absorption layer and a bottom layer from top to bottom, an inner surface contact layer is attached to the inner surface of the surface layer, the inner surface contact layer is a silk layer, the silk layer is formed by weaving natural silk fiber, the surface layer is prepared from, in percentage by mass, 30-60% of natural silk fiber and 40-70% of plant fiber, the plant fiber is a mixture of jute fiber, velveteen fiber and bamboo charcoal fiber, and the bottom layer is a liquid-impermeable thermoplastic synthetic resin film. The pure silk diaper has good skin-friendly property, no irritation to skin, no anaphylactic reaction, antisepsis and anti-inflammation, and is soft, comfortable, dry and breathable in use.

Description

technical field [0001] The invention relates to the technical field of products for infants and young children, in particular to a pure silk diaper and a preparation method thereof. Background technique [0002] Diapers are one of the commonly used care products for infants and young children. Existing diapers are usually composed of a three-layer layered structure. The bottom layer is a plastic film with waterproof function, which prevents moisture from penetrating outward and plays a good role in water isolation. , the middle interlayer is a water-absorbent material with excellent water absorption and water storage capacity, and the surface layer is non-woven fabric. [0003] However, most of the existing non-woven fabrics are made of synthetic fibers. Synthetic fibers have poor hygroscopicity. Long-term use is likely to cause symptoms such as skin itching and red buttocks in infants and young children. Moreover, the surface of non-woven fabrics has poor softness and rough...
