Abstract
The utility model relates to a superfine denier sheath-core type composite short fiber, including cortex and sandwich layer, the sandwich layer is by the cladding in the cortex, and the fibre number is 0.5 ~ 1.0D. Adopt the utility model discloses the defending material and the non-woven fabrics of product production have frivolous, soft, ventilative advantage, satisfy defending the more and more thin requirement of material and non-woven fabrics to it is durable to be durable.
Description
Technical field
The utility model relates to a kind of super fine denier core-skin type composite short fiber.
Background technology
The core-skin type composite short fiber has more superior performance as substituting the fiber of new generation that viscose uses than single component fiber, and more environmental protection, receives the favor of defending material and nonwoven production producer.The fiber number of core-skin type composite short fiber generally more than 1.0D, can't satisfy and defend requirement more and more thinner in material and the nonwoven production in the market.
The utility model content
The purpose of the utility model provides a kind of super fine denier core-skin type composite short fiber of defending material and nonwoven production that is applicable to.
The technical scheme of the utility model is: a kind of super fine denier core-skin type composite short fiber, comprise cortex and sandwich layer, and sandwich layer is coated in the cortex, and fiber number is 0.5～1.0D.
Fiber cross section can have different shapes, comprises that specifically circular concentric, eccentric circle, sandwich layer are that odd-shaped cross section or core-skin are odd-shaped cross section, and the cross section of this fiber is preferably circular concentric.
Cortex can be PE, and sandwich layer can be PP or PET, and as a kind of preferred version, said cortex is PE, and said sandwich layer is PP.
The beneficial effect of the utility model is: that adopts the utility model production defends material and nonwoven fabric, has frivolous, soft, ventilative advantage, and satisfy and defend the requirement that material and nonwoven fabric more and more approach, and durable.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the technological process of production figure of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Super fine denier core-skin type composite short fiber as shown in Figure 1 comprises cortex 1 and sandwich layer 2, and cortex 1 is PE, and sandwich layer 2 is PP, and sandwich layer 2 is coated in the cortex 1, and the cross section of fiber is a circular concentric, and fiber number is 0.5～1.0D.
The production technology of said super fine denier core-skin type composite short fiber is as shown in Figure 2, and common process is all adopted in each step operation, and wherein, the mass ratio of PP raw material and PE raw material is 40: 60.
After cut off, packing obtains super fine denier core-skin type composite short fiber.
Certainly, the difform spinnerets of employing also can make eccentric circle in composite spinning, sandwich layer is the super fine denier core-skin type composite short fiber that odd-shaped cross section or core-skin are odd-shaped cross section.
Claims (3)
1. a super fine denier core-skin type composite short fiber comprises cortex and sandwich layer, and sandwich layer is coated in the cortex, it is characterized in that: fiber number is 0.5～1.0D.
2. by the described super fine denier core-skin type of claim 1 composite short fiber, it is characterized in that: the cross section of this fiber is a circular concentric.
3. by claim 1 or 2 described super fine denier core-skin type composite short fibers, it is characterized in that: said cortex is PE, and said sandwich layer is PP.
