Abstract
The present invention discloses a sheath-core papermaking molding net monofilament, which is sheath-core fiber, wherein, a core layer is polytrimethylene terephthalate or polybutylene terephthalate; a skin layer is polyethylene terephthalate. The present invention is soft in fiber, can prolong the life-span of a molding net by more than 20 percent when compared with the prior common molding net fiber, and is good in the size stability of fiber.
Description
Technical field:
The present invention relates to a kind of chemical fibre.
Background technology:
Existing papermaking forming web fiber is generally single component, and fiber softening, DIMENSIONAL STABILITY are all undesirable, and the service life of forming web is short.
Summary of the invention:
The object of the present invention is to provide a kind of fiber softening, make the core-skin type paper making modeling net filament of forming web long service life.
Technical solution of the present invention is:
A kind of core-skin type paper making modeling net filament is characterized in that: be sheath core fiber, its center core layer is polytrimethylene terephthalate or polybutylene terephthalate, and cortex is polyethylene terephthalate.
The weight of cortex accounts for 20～50% of monofilament weight, and sandwich layer weight accounts for 50～80% of monofilament weight.
Fiber softening of the present invention is compared with existing common forming web fiber forming web is prolonged more than 20% service life, and the DIMENSIONAL STABILITY of fiber is good.
The invention will be further described below in conjunction with embodiment.
The specific embodiment:
Embodiment:
Make the method for sheath core fiber routinely and make sheath core fiber,, in 40 ℃ water, cool off then 290 ℃ of following extrusion moldings, after one-level stretches 1.3 times of 4 times, secondary drawing,, coiled into the limit monofilament again 240 ℃ of following HEAT SETTING, twist with the fingers into four strands or six strands, promptly get product.Be core material with polytrimethylene terephthalate or polybutylene terephthalate when making sheath core fiber, with the polyethylene terephthalate is cortical material, and the weight of cortical material accounts for 20～50% (examples 20%, 35%, 50%) of raw material gross weight, and sandwich layer weight accounts for 50～80% (examples 50%, 65%, 80%) of total raw material weight.
Claims (2)
1. core-skin type paper making modeling net filament is characterized in that: be sheath core fiber, its center core layer is polytrimethylene terephthalate or polybutylene terephthalate, and cortex is a polyethylene terephthalate.
2. core-skin type paper making modeling net filament according to claim 1 is characterized in that: the weight of cortex accounts for 20～50% of monofilament weight, and sandwich layer weight accounts for 50～80% of monofilament weight.
