Number be 15 × 18 × 42 × 3R24 large needle fine needle diameter pricker and the short flute profile needle cloth of model NC3510*02080VP-50 fine needle
It handles to obtain the tangerine valve type PA/PET bicomponent fibers by fibrillation.
Wherein, the pricker frequency is pre- thorn 420 thorns/min, main thorn 480 thorns/min.
Ultra-fine bicomponent fibers compound spiked felt described in the utility model, by tangerine valve type PA/PET bicomponent fibers
It is mixed into a certain proportion of fine-denier acrylic fiber, the thermal stability of product entirety can be improved, to reduce product percent thermal shrinkage, is prevented
The related contraction blocking in the fine aperture for only causing it internal because of contraction reduces air permeability.Again to three kinds of composite fibre through specific
The combing of carding machine thin needle cloth, and reasonable needing machine fine needle pricker and needle frequency needling action, so that the double groups of tangerine valve therein
After point fiber is by fibrillation processing, obtain micron-class superfine denier fiber, and with other two kinds of fibers intertwine with each other obvolvent formed it is close
The fine voids of collection, it is ensured that effective flue gas passes through, and reduces running resistance, has good filter effect to fine dust；Simultaneously
Using the mechanical fibrillation of combing and needle thorn mode, moreover it is possible to achieve the effect that time-saving energy-saving.
Detailed description of the invention
Fig. 1 is ultra-fine bicomponent fibers compound spiked felt structural schematic diagram described in the utility model embodiment.
Specific embodiment
In the following, the utility model is described in detail in conjunction with attached drawing.
As shown in Figure 1, present embodiments providing a kind of ultra-fine bicomponent fibers compound spiked felt, including base cloth layer 3 and patch
The micron-class superfine denier fibrous layer for being used to intercept fine particle dusts of 3 upper and lower surface of base cloth layer is invested, the fibrous layer includes:
Polyester fiber, by mechanical fibrillation handle with obtain micron-class superfine denier fiber tangerine valve type PA/PET bicomponent fibers and with it is preceding
It states two kinds of fibers and intertwine with each other obvolvent to form the fine-denier Asia that can improve product entirety thermal stability in fine intensive aperture
Gram force fiber.Here, PA is polyamide, is commonly called as nylon.PET (polyester fibre, polyester fiber), is commonly called as terylene.
Wherein, the tangerine valve type PA/PET bicomponent fibers specification is 3D × 51mm, and valve number is 24 valves；The fine-denier
Acrylic fiber specification is 1.0dtex × 51mm, and the polyester fiber specification is 2.2dtex × 51mm.
Monofilament effective fiber fineness is 0.1dtex after the tangerine valve type PA/PET bicomponent fibers fibrillation, with other two kinds
