Abstract

The utility model relates to a single filament for brushes and pens with polyytrimethylene terephthalate (PPT), which is in a shape of solid filament or hollow filament or profiled filament or sharpening filament or pseudo bristle filament or wavy filament, characterizing in that the filament has high elastic restitution rate above nylon 612 filaments, and easy cleaning, low cost, excellent versatility of manufacturing facilities could be obtained.

Description

Polytrimethylene terephthalate PTT producing brush and pen monofilament

Technical field

The utility model relates to the monofilament shape that a kind of producing brush and pen is used.

Background technology

At present, in the producing brush and pen field, the chemical fibre monofilament as woolen cloth mainly adopts nylon, PBT, PET, PP, PVC etc., but wherein nylon price height, not easy cleaning; PBT, PET, PP elastic recovery rate are low; PVC is unfavorable for environmental protection.

Summary of the invention

The utility model purpose is to provide a kind of elastic recovery rate height, easy cleaned producing brush and pen monofilament.

For solving foregoing problems, the utility model provides a kind of polytrimethylene terephthalate PTT producing brush and pen monofilament, and the monofilament of making is shaped as solid silk or air silk or cross section special-shaped silk or sharpening brushing or artificial bristle wire or corrugation.

The utility model has the advantages that:

1, elastic recovery rate height, according to the character of polytrimethylene terephthalate itself, response rate even be higher than nylon;

2, easy cleaning;

3, cheap, be easy to expand the scale of production;

4, manufacturing equipment highly versatile spins monofilament equipment and does slightly to improve and adjust highly versatile owing to only need to have now.

Description of drawings

Fig. 1 is to be the common chemical fibre monofilament of raw material with polytrimethylene terephthalate PTT.

Fig. 2 A is that the cross section is the PTT chemical fibre monofilament of circular real core.

Fig. 2 B is that the cross section is circular, and there is PTT chemical fibre monofilament hollow more than inside.

Fig. 2 C is that the cross section is the PTT chemical fibre monofilament of three lobes or pintongs or the real core of five lobes abnormity.

Fig. 2 D is the PTT sharpening brushing that head is fined away.

Fig. 2 E is that head is branched into the artificial bristle wire with two above tips.

Fig. 2 F is the PTT corrugation that integral body is the corrugated distortion.

The specific embodiment

Embodiment one

Accompanying drawing 1 is to be the common chemical fibre monofilament of raw material or main raw material with polytrimethylene terephthalate PTT.As accompanying drawing 2A is that the cross section is the PTT chemical fibre monofilament of circular real core, is raw material with polytrimethylene terephthalate PTT, is used to make paint brush or cleaning brush or cosmetic brush or toothbrush or pen.

The present embodiment result of use is:

1, polytrimethylene terephthalate PTT chemical fibre monofilament spins monofilament equipment with routine and mould is made;

2, PTT has had both the rigidity of PET and the flexibility of PBT, at the 20% o'clock elastic recovery rate that stretches near 100%;

3, the PTT raw material needs stored dry, its extrusion temperature, draft temperature, qualitative temperature and percent thermal shrinkage to be easy to control, and pollution resistance is good, water imbibition is low.

Embodiment two

As accompanying drawing 2B is that the cross section is circular, and there are one or more hollow PTT chemical fibre monofilament inside, and its purposes, performance are close with embodiment one.

Embodiment three

Present embodiment provides cross section special-shaped monofilament structure, is that the cross section is the PTT chemical fibre monofilament of three lobes or pintongs or the real core of five lobes abnormity as accompanying drawing 2C, and its purposes, performance are close with embodiment one.

Embodiment four

Present embodiment provides sharpening brushing and artificial bristle wire, is the sharpening brushing that head is fined away as accompanying drawing 2D.As accompanying drawing 2E is that head is branched into the artificial bristle wire with two above tips, and its purposes, performance are close with embodiment one.

Embodiment five

As accompanying drawing 2F is the corrugation that integral body is the corrugated distortion, and one embodiment one is close for its purposes, performance.

Claims

1, a kind of polytrimethylene terephthalate producing brush and pen monofilament is characterized in that: use polytrimethylene terephthalate, make and be shaped as solid silk or air silk or cross section special-shaped silk or sharpening brushing or artificial bristle wire or corrugation.
