Abstract
The utility model discloses a kind of high mould lower shrinkage spinneret, its gross thickness is 34mm, including spinnerette body, spinnerette body end face is charging face, a diameter of 220mm, other end is for going out charge level, a diameter of 194mm, is disposed with spinneret orifice on described spinnerette body, and spinneret orifice includes guide hole and corresponding pore, the a diameter of 3mm of its centre feed hole, its entrance chamfering α is 90 °, and bottom convergence angle beta is 70 °, a diameter of 0.85mm of pore, a length of 1.10mm, described spinneret orifice Structural assignments ringwise on spinnerette body.The large aperture annular spinneret of this utility model R & D design, jet stretch multiple can be effectively improved in conjunction with high-speed spinning low draft process route, the degree of crystallinity and the modulus that make material are higher, and under the stretching condition identical with common HMLS polyester industrial yarn production technology, strength substantially increases.
Description
Technical field
This utility model relates to a kind of high mould lower shrinkage spinneret, belongs to polyester industrial yarn technical field of textile equipment.
Background technology
HMLS terylene (HMLS) polyester fiber is a kind of dimensional stability high intensity of exploitation at the end of the seventies in last century
Polyester fiber, the feature prominent compared with plain edition polyester fiber of this polyester fiber is: initial modulus is high, and anamorphic stretching is little,
Dimensionally stable, dynamic heat build up is little, and especially high-temperature hot shrinkage factor is little, and is that percent thermal shrinkage is than plain edition polyester fiber at low temperature
Greatly.The cotton rope made with this fiber is particularly suitable for the use of transmission band.HMLS silk typically uses polyester industrial yarn raw at present
Produce route, shape through multistage drafting from the melt of spinneret micropore extrusion so that product strength or dry-hot shrinkage reach pre-
Phase requirement.But the spinneret orifice that production HMLS silk is used at present is mainly 0.35-0.65mm small-bore, draw ratio at 2-3 times
High length-diameter ratio design, this design concept only to improve for the purpose of production stability, does not takes into account the dimensional stability of HMLS silk
And strength loss.And the main feature of HMLS silk is high intensity and lower shrinkage.Therefore, the HMLS that existing spinneret produces is used
Silk performance is unsatisfactory.
Utility model content
The technical problems to be solved in the utility model is: provides a kind of high mould lower shrinkage spinneret, can effectively reduce HMLS
The strength loss of polyester industrial yarn, can overcome the deficiencies in the prior art.
The technical solution of the utility model is: a kind of high mould lower shrinkage spinneret, its gross thickness 34mm, including spinneret originally
Body, spinnerette body end face is charging face, diameter 220mm, and other end is for going out charge level, and diameter 194mm, at described spinneret
Being disposed with spinneret orifice on body, spinneret orifice includes guide hole and corresponding pore, a diameter of 3mm of its centre feed hole, its entrance chamfering α
Being 90 °, bottom convergence angle beta is 70 °, and a diameter of 0.85mm of pore, a length of 1.10mm, described spinneret orifice is at spinnerette body
On Structural assignments ringwise.
Described spinneret orifice is distributed as 4 to 8 circles on spinnerette body.
The often circle spinneret orifice hole count being distributed on described spinnerette body is consistent, for 50-80 hole.
Described spinnerette body zone line is uniformly distributed in around central area without spinneret orifice, spinneret orifice.
The beneficial effects of the utility model are: the large aperture annular spinneret of this utility model R & D design, spin in conjunction with height
Speed low draft process route can be effectively improved jet stretch multiple, make the degree of crystallinity of material and modulus higher, with commonly
Under the stretching condition that HMLS polyester industrial yarn production technology is identical, strength substantially increases.
Accompanying drawing explanation
Fig. 1 is side view of the present utility model；
Fig. 2 is front view of the present utility model；
Fig. 3 is the structural representation of this utility model spinneret orifice.
Detailed description of the invention
Below in conjunction with the accompanying drawings and utility model is described further by specific embodiment:
Embodiment 1:
As shown in Figure 1 to Figure 3, a kind of high mould lower shrinkage spinneret of this utility model, improve at existing spinneret, bag
Including its gross thickness is 34mm, rounded spinnerette body, and spinnerette body end face is charging face 1, a diameter of 220mm, separately
End face for going out charge level 2, a diameter of 194mm, described spinnerette body is disposed with spinneret orifice 3, spinneret orifice 3 includes guide hole 4
With corresponding pore 5, a diameter of 3mm of its centre feed hole 4, its entrance chamfering α is 90 °, and bottom convergence angle beta is 70 °, pore 5
A diameter of 0.85mm, a length of 1.10mm, spinneret orifice 3 Structural assignments ringwise on spinnerette body, specifically, spinneret orifice 3
Spinnerette body is distributed as 5 circles, and often circle spinneret orifice 3 hole count is consistent, is 64 holes, at spinnerette body zone line without spray
Silk hole 3, spinneret orifice 3 is uniformly distributed in around central area.
Embodiment 2:
Except spinneret orifice 3 is distributed as 6 circles on spinnerette body, and often circle spinneret orifice 3 hole count is consistent, is outside 64 holes, remaining
Same as in Example 1.
Embodiment 3:
Except spinneret orifice 3 is distributed as 8 circles on spinnerette body, and often circle spinneret orifice 3 hole count is consistent, is outside 60 holes, remaining
Same as in Example 1.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to
Assert that of the present utility model being embodied as is confined to these explanations.Ordinary skill for this utility model art
For personnel, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should regard
For belonging to protection domain of the present utility model.
