A kind of wiping polyethylene/polyester is with bundle isomery composite fibreTechnical field
The present invention relates to a kind of wiping polyethylene/polyester with bundle isomery composite fibre.
Background technology
Existing one wipes composite fibre on probation, mainly contain 1.5D-6.0Dx3mm-64mm equal-specification, in use become dust-free paper, the nonwoven fabric of corresponding specification by the processes such as hot blast, hot rolling, be widely used in products such as making sanitary napkin, children's's diaper, adult diaper.Because above-mentioned composite fibre is single concentric circles core-sheath compound fibre, its composite bending modulus low, indifference relative to Curl, thus in the application aspect of wiping with product of keeping a public place clean, does not reach due effect.Along with the raising of people's living standard, wiping product of keeping a public place clean more and more is subject to the favor of consumers in general, and high-performance, wiping that is differential, low cost product of keeping a public place clean has become consumer's active demand.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of wiping polyethylene/polyester with bundle isomery composite fibre, effective in wiping is kept a public place clean of this fiber, thus consumers in general can be met to high-performance, the demand that differential, product is kept a public place clean in wiping that is low cost.
For solving the problems of the technologies described above, a kind of wiping polyethylene/polyester of the present invention, with bundle isomery composite fibre, is characterized in that: the set containing at least 100 composite fibres, its single composite fibre is divided intotype andtype version:type version is cross section take polyethylene as annular coating, and with polyester for circular inner core, the polyester of this circular inner core is arranged in annular coating polyethylene, the antistatic oil film of coated one deck on the poly outer surface of this annular coating;type version is cross section is annular coating with polyethylene, take polyester as trilobal inner core, and the polyester of this trilobal inner core is arranged in annular coating polyethylene, the antistatic oil film of coated one deck on the poly outer surface of this annular coating;type andthe single composite fibre of type is arranged in order on direction, front, rear, left and right.
Describedtype andthe length of the single composite fibre of type is 5-106mm, and fiber number is 1D at least, and fracture strength is 2.8cN/dtex at least, and extension at break is 50-100%, and crispation number is 5-30/25mm.
At above-mentioned a kind of wiping polyethylene/polyester with in bundle isomery composite fibre, have employed the complex structure of filament of the same bundle isomery of circular inner core or trilobal inner core, the composite bending modulus of fibre bundle and Curl have been had and significantly improves; Meanwhile,the single composite fibre of the circular inner core of type andthe single composite fibre of the trilobal inner core of type is arranged in order on direction, front, rear, left and right, difference each other on composite bending modulus and crimp property, thus cause fibre bundle to form the clamping soil pick-up effect of coupling hardness with softness when wiping micronic dust, the dust-absorbing rate of fiber significantly improves, therefore effective in wiping is kept a public place clean of this fiber, thus consumers in general can be met to high-performance, the demand that differential, product is kept a public place clean in wiping that is low cost.

Detailed description of the invention
In Fig. 1, a kind of wiping polyethylene/polyester of the present invention is with bundle isomery composite fibre, and the set containing at least 100 composite fibres, its single composite fibre is divided intotype andtype version:type version be cross section with polyethylene (PE) be annular coating 5, its endoporus is for circular, with polyester (PET) for circular inner core 6, the polyester (PET) of this circular inner core 6 is arranged in annular coating 5 polyethylene (PE), the antistatic oil film 4 of coated one deck on the outer surface of the polyethylene (PE) of this annular coating 5.type version be cross section with polyethylene (PE) be annular coating 2, its endoporus is for trilobal, with polyester (PET) for trilobal inner core 3, the polyester (PET) of this trilobal inner core 3 is arranged in annular coating 2 polyethylene (PE), the antistatic oil film 1 of coated one deck on the outer surface of the polyethylene (PE) of this annular coating 2.type andthe single composite fibre of type is arranged in order on direction, front, rear, left and right, as shown in Figure 1.
Describedtype andthe length of the single composite fibre of type is 5-106mm, and fiber number is 1D at least, and fracture strength is 2.8cN/dtex at least, and extension at break is 50-100%, and crispation number is 5-30/25mm.
At above-mentioned a kind of wiping polyethylene/polyester with in bundle isomery composite fibre, have employed the complex structure of filament of the same bundle isomery of circular inner core 6 or trilobal inner core 3, the composite bending modulus of fibre bundle and Curl have been had and significantly improves; Meanwhile,the single composite fibre of the circular inner core 6 of type andthe single composite fibre of the trilobal inner core 3 of type is arranged in order on direction, front, rear, left and right, difference each other on composite bending modulus and crimp property, thus cause fibre bundle to form the clamping soil pick-up effect of coupling hardness with softness when wiping micronic dust, the dust-absorbing rate of fiber significantly improves, therefore effective in wiping is kept a public place clean of this fiber, thus consumers in general can be met to high-performance, the demand that differential, product is kept a public place clean in wiping that is low cost.
In order to realize a kind of wiping polyethylene/polyester of the present invention with bundle isomery composite fibre, specialized designs has manufactured spinneret device between a kind of special preparation wiping polyethylene/polyester same complete homogeneous phase restrainting isomery composite fibre, and general composite fibre production line is manufactured; The manufacture of this spinneret design, adopts the rheology principle method of spinneret orifice equivalence spray silk sectional area, to ensure the homogeneity of the fiber number of fiber, compound ratio, fracture strength, extension at break.Also manufactured and designed a kind of special preparation wiping polyethylene/polyester with drawing-off, the crimping device of restrainting isomery composite fibre simultaneously, the composite bending modulus of each single composite fibre and crimp property are significantly improved and difference each other, cause fibre bundle to form the clamping effect of coupling hardness with softness when wiping micronic dust, thus the dust-absorbing rate of fiber is significantly improved.Meet consumers in general to high-performance, the demand that differential, product is kept a public place clean in wiping that is low cost.
