Abstract
The utility model discloses a composite skin-core staple fiber. The section of the staple fiber is a skin-core structure, the length of the staple fiber is 3-200 mm, the monofilament size is not less then 0.1 D, and the crispation number is 0-40 per 25 mm; the outer surface of the fiber is covered with a hydrophilic oil film. The utility model has excellent properties of hydrophilicity, permeability of water, and hydroscopicity.
Description
Technical field
The utility model relates to a kind of compound sheath-core staple fibre of material of defending.
Background technology
The structure that is used to defend the composite short fiber of material at present is a core-skin type.Its fiber number is not less than 0.5D, crispation number is that 5～18/25mm, crimp percent are 10～18%, therefore because the reasons in structure of itself, its hydrophilicity is relatively poor, thereby can not satisfy products such as road, back non-weaving cloth, dust-free paper, to requirement close, saturating, water absorbing properties.
The utility model content
The technical problems to be solved in the utility model provides a kind of compound sheath-core staple fibre of material of defending, and it has the good parent to water, saturating, absorption energy.
In order to solve the problems of the technologies described above, a kind of compound sheath-core staple fibre of material of defending of the utility model, its cross section is a skin-core structure, and its length is that 3～200mm, fiber number are not less than 0.1D, 0～40/25mm of crispation number, and the outer surface of this fiber coats one deck hydrophilic oil film.
Because a kind of material of defending of the utility model is that length 3～200mm, fiber number are not less than 0.1D, 0～40/25mm of crispation number with compound sheath-core staple fibre, its surface coats the fiber of one deck hydrophilic oil film.Being not less than 0.5D, crispation number with existing fiber number is that 5～18/25mm, crimp percent are that 10～18% compound sheath-core staple fibre is compared, and the utlity model has the good parent to water, saturating, absorption energy.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the material of defending shown in Figure 1 is analysed and observe enlarged diagram with the cross section of compound sheath-core staple fibre.
1. defend the compound sheath-core staple fibre of material, 2. hydrophilic oil film among the figure.
The specific embodiment
Among Fig. 1, defending material is the fiber that length 3～200mm, fiber number are not less than 0.1D, 0～40/25mm of crispation number with compound sheath-core staple fibre 1.Defend the surface coating one deck hydrophilic oil film 2 of material, as shown in Figure 2 with compound sheath-core staple fibre 1.The cross section of compound sheath-core staple fibre 1 is a skin-core structure.The set of above-mentioned fiber can be processed into products such as sanitary napkin, children's's diaper, adult diaper.Defending material, to be not less than 0.5D, crispation number with compound sheath-core staple fibre 1 and existing fiber number be that 5～18/25mm, crimp percent are that 10～18% compound sheath-core staple fibre is compared, and it has the good parent to water, saturating, absorption energy.Practice shows that permeability rate of the present utility model and water absorption rate are two to three times of prior art.
Claims (1)
1. defend the compound sheath-core staple fibre of material for one kind, its cross section is a skin-core structure, it is characterized in that: its length is that 3～200mm, fiber number are not less than 0.1D, 0～40/25mm of crispation number, and the outer surface of this fiber coats one deck hydrophilic oil film.
