Description

Multipurpose double-layer solid core composite monofilament

Technical field

The utility model relates to arrive fibre technology field, especially a kind of double-deck solid core composite monofilament.

Background technique

Existing water-absorption fiber stick is combined by the monofilament of pure PET (terylene) or PP (polypropylene) material, this A little fiber filaments as water-absorbing core are to be bonded together by glue, and made inside fiber filament tightly using certain process The club shaped structure of close bonding and the certain elasticity of formation, there are the following problems: fiber filament itself has certain water imbibition and mistake Filter property, however the fiber filament of solid core structure uses in terms of water imbibition and for the filter tip of electronic cigarette when as water suction rod When, since cored structure in fact can be to its water imbibition and capillary suction according at certain influence, when as a kind of Smoke Filter In use, making the penetrability of smog strong not enough containing the filametntary fiber stick of solid core.

206680627 U of patent document CN discloses " a kind of bilayer hollow composite monofilament ", and the monofilament is using Gao Rong The extexine structure of the hollow inner sandwich layer, low melting point put, so that monofilament has good water guide, water suction, strainability, so And since the fusing point of extexine is relatively low, the monofilament of more only remaining inner sandwich layers will be mutual after extexine dissolution It is bonded together, so that its water guide, water suction, strainability can be seriously affected.

Utility model content

For above-mentioned technical problem of the existing technology, has the purpose of this utility model is to provide one kind and preferably lead Water, water suction, strainability the double-deck solid core composite monofilament.

Realize above-mentioned purpose, the technical solution of the utility model is:

Multipurpose double-layer solid core composite monofilament, including extexine and inner sandwich layer, the extexine are coated on the table of inner sandwich layer Face, inner sandwich layer are solid core pipe structure, and pore gap is formed between inner sandwich layer and the contact surface of extexine；The inner sandwich layer is served as reasons Low melting point inner sandwich layer made of PE or PP or POE material；The extexine is the Gao Rong made of PET or TPU or TPEE material Point extexine；The fusing point of the low melting point inner sandwich layer is lower than the fusing point of high-melting-point extexine.

The fusing point of the POE material is 50-90 degree, and the fusing point of PE material is 120-140 degree, and the fusing point of PP material is 150- 170 degree, the fusing point of TPU material is 170-210 degree, and the material melting point of TPEE is 190-220 degree, and the fusing point of PET material is 240- 260 degree.

The every composite monofilament Denier range is 3D-12D, and the D is Denier.

The utility model compared with prior art, the beneficial effect is that:

By inner sandwich layer being designed to solid core structure and inner sandwich layer is using existing low melting material, and extexine Be then using existing materials with high melting point and inner sandwich layer being coated, since inner sandwich layer is using existing low melting material, Together with it is difficult to blend with the existing materials with high melting point of extexine, thus the shape between inner sandwich layer and the contact surface of extexine At a large amount of tiny pore gaps, in this way, in normal use, the composite monofilament of this structure also has that " the double-deck hollow is compound The good water guide of monofilament ", water suction, strainability, simultaneously as extexine is using existing materials with high melting point, surface Compare and be difficult to dissolve, therefore the monofilament phase for leading to more only remaining inner sandwich layers because of extexine dissolution can be effectively reduced The generation of mutual bonding phenomenon, thereby may be ensured that water guide, water suction, the strainability of composite monofilament.

In figure: 1, extexine；2, inner sandwich layer；3, pore gap.

Specific embodiment

As shown in fig.1, for the cross-sectional structure schematic diagram of the double-deck solid core composite monofilament provided in this embodiment, the bilayer Solid core composite monofilament includes extexine 1 and inner sandwich layer 2, and extexine 1 is coated on the surface of inner sandwich layer 2, and inner sandwich layer 2 is solid core pipe knot Structure, in the present embodiment, inner sandwich layer 2 is using existing PP (polypropylene) material, and fusing point is 150-170 degree, and appearance Layer 1 is then using existing PET (terylene) material, and fusing point is 240-260 degree, since the fusing point of inner sandwich layer is far below appearance Layer, together with inner sandwich layer is difficult to blend with extexine, to be formed between inner sandwich layer 2 and the contact surface of extexine 1 a large amount of Tiny pore gap 3, in this way, the composite monofilament of this structure also has " the double-deck hollow composite monofilament " in normal use Good water guide, water suction, strainability, simultaneously as extexine, using existing materials with high melting point, surface is more difficult With dissolution, therefore can be effectively reduced causes the monofilament of more only remaining inner sandwich layers mutually to bond because of extexine dissolution The generation of phenomenon thereby may be ensured that water guide, water suction, the strainability of composite monofilament.

Certainly in other embodiments, inner sandwich layer can use existing POE material (fusing point is 50-90 degree) or PE material (fusing point is 120-140 degree)；And extexine can then use existing TPU material (fusing point is 170-210 degree) or PEE material (fusing point is 190-220 degree).

Simultaneously can also according to demand, 21 component of extexine accounts for the 40%-60% of total amount, and 22 component of inner sandwich layer accounts for total amount 60%-40%.

The every composite monofilament Denier range is 3D-12D, and the D is Denier.

Specifically, the making step of the double-deck solid core composite monofilament provided in this embodiment is specific as follows

Step 1: production solid core inner sandwich layer single layer fibre, low melting material needed for choosing inner sandwich layer as needed are melting It is reacted, and is removed slag, acid-base neutralization in case, carry out crystallizing and drying, drying temperature 50-60 degree, drying time 6-18 hour does Single layer fibre after dry carries out after melt extruded plus bullet processing, to form the single layer fibre silk of solid core structure；By adding bullet to add Work processing can make the surface of in-core sandwich layer single layer fibre form more pores；

Step 2: production extexine single layer fibre, materials with high melting point needed for choosing extexine as needed, in melting case It is reacted, and is removed slag, acid-base neutralization, carry out crystallizing and drying, drying temperature 90-100 degree is drying time 12-14 hour, dry Single layer fibre afterwards enters extexine channel after melt extruded, and extexine channel includes spray chamber, and the docking of extexine channel is same Spinneret；

Step 3: inner sandwich layer single fiber and extexine single fiber are combined into the fiber with double-layer structure at spinneret Silk, the extexine are coated on inner sandwich layer outer surface, are drawn after the double layer fibre silk is cooling by dragger, will be double-deck fine Wei Sila is to required length and diameter；

Step 4: double layer fibre silk is carried out using elasticizer plus bullet is by fiber formation pore and the better DTY of bulkiness Fiber filament.

Certainly, it says it is noted that " low melting point " and " high-melting-point " in the application is in contrast " low " and "high" When one relative adjective.

For above-described embodiment simply to illustrate that the technical ideas and features of the present invention, its purpose is allows this field Interior those of ordinary skill can understand the content of the utility model and implement accordingly, can not limit the utility model with this Protection scope.The equivalent changes or modifications that all essence according to the content of the present invention is made, should all cover in this reality With in novel protection scope.
