Abstract

The utility model relates to a spinneret plate with improved structure, which belongs to the technical field of polyester/polyamide composite filament spinning device. The spinneret plate comprises a plate body provided with a polyamide molten mass through hole and a polyester molten mass through hole and a group of spinnerets arranged on the plate body at intervals and provided with cross-shaped grooves and through holes. The spinneret plate is characterized in that the width and the depth of each cross-shaped groove is 0.11-0.13 mm. The spinneret plate has the advantages that the reasonable selection of challenge significance is made to the structure of the cross-shaped groove on the spinneret in the prior art, thereby being helpful for saving the raw material of polyamide and favorable for meeting the reasonable requirement on use of filaments for different face fabric.

Description

Improve the spinnerets of structure

Technical field

The utility model belongs to the technical field of spinning of washing bright and beautiful bicomponent filament yarn, is specifically related to a kind of spinnerets that improves structure.

Background technology

Industry is known, in washing the process of bright and beautiful bicomponent filament yarn, need to use spinnerets, with the bright and beautiful compounding flux ejection of washing of molten, form tow by spinnerets, batch by coiler device after the lateral blowing device side blowing through being located at the manifold bottom, cooling device cooling and oiling device oil.On spinnerets, dispose numerous spinning heads, constitute meter a word groove and a through hole on each spinning head, the melt that enters in meter word groove is the polyamide fibre melt, the melt that enters in the through hole then is the terylene melt, therefore resulting cross sectional form of washing bright and beautiful bicomponent filament yarn shows as M shape, the raw material of the stroke part of rice word is a polyamide fibre, and the raw material of the remainder of stroke then is a terylene.

The width of the rice word groove of each spinning head on the spinnerets in the prior art and the degree of depth are defined in usually and respectively are 0.15mm, the silent usually specification of keeping or claim to defer to this meter word groove of industry, and as if dare not get over river in ancient China, when the width of rice word groove and the degree of depth respectively are 0.15mm, the so resulting shared mass percent of terylene of washing in the bright and beautiful bicomponent filament yarn is 80%, and the shared mass percent of polyamide fibre is 20%.But in some cases, often do not need content with polyamide fibre to remain in 20% degree, therefore, simply the content of polyamide fibre is remained in 20% if do not treat with a certain discrimination, can give the production firm of washing bright and beautiful bicomponent filament yarn so on the contrary and use the manufacturer of washing bright and beautiful bicomponent filament yarn to cause puzzlement, here alleged puzzlement is meant: produce the cost of washing bright and beautiful bicomponent filament yarn as the production firm of washing bright and beautiful bicomponent filament yarn and occupy high, because the price per ton of slices of caprone raw material reaches more than ten thousand yuan, produce the unit of various linings because of costing an arm and a leg worry and wash bright and beautiful bicomponent filament yarn as utilization, particularly for the common lining of processing, also as if there is no need even if the shared mass percent of polyamide fibre is high again, even can cause the inaction of materials of the synthetic fibre to expend.In view of this, be necessary the structure of the spinnerets in the prior art is improved, so that not only embody save expensive materials of the synthetic fibre but also satisfy common lining with thread between find rational equalization point, technical scheme described below produces under this background.

Summary of the invention

Task of the present utility model is to provide a kind of and not only helps to save materials of the synthetic fibre but also help adapting to the spinnerets of different linings with the improvement structure of silk requirement.

Task of the present utility model is finished like this, a kind of spinnerets that improves structure, comprise plate body, offer polyamide fibre melt through hole and terylene melt through hole on the plate body, one group of spinning head, with the interval state be formed on the plate body, offer meter a word groove and a through hole on each spinning head, characteristics are: the width of described rice word groove and the degree of depth respectively are 0.11-0.13mm.

The width and the degree of depth of rice word groove described in the utility model respectively are 0.12mm.

The advantage of the technical scheme that the utility model is recommended: because the structure of the rice word groove on the spinning head in the prior art has been carried out challenging choose reasonable, therefore both helped to save materials of the synthetic fibre, helped satisfying of the reasonable request of different linings again with silk.

The specific embodiment

Embodiment 1:

Ask for an interview Fig. 1 to Fig. 3, provided plate body 1, this plate body 1 is discoidal, and be formed with a step chamber 13, in step chamber 13 with the interval state offer polyamide fibre melt through hole 11 and terylene melt through hole 12, and in step chamber 13 with the interval state constitute the spinning head 2 that one group of quantity is not subjected to illustrating restriction, offer meter word groove 21 and through hole 22 on each spinning head 2, what flow through in the rice word groove 21 is the polyamide fibre melt, and what flow through in the through hole 22 is the terylene melt.Figure 2 illustrates meter width of word groove 21 is 0.12mm; Figure 3 illustrates meter degree of depth of word groove 21 is 0.12mm.

Embodiment 2:

Figure omits, and only the width and the degree of depth with rice word groove 21 respectively changes 0.13mm into, and all the other are with the description to embodiment 1.

Embodiment 3:

Figure omits, and only the width and the degree of depth with rice word groove 21 respectively changes 0.11mm into, and all the other are with the description to embodiment 1.

Both helped to save expensive materials of the synthetic fibre by the resulting spinnerets of the foregoing description 1-3, the shared mass percent of polyamide fibre that can satisfy again washing in the bright and beautiful bicomponent filament yarn is lower than a lining silk requirement of 20%.

Claims

1, a kind of spinnerets that improves structure, comprise plate body (1), offer polyamide fibre melt through hole (11) and terylene melt through hole (12) on the plate body (1), one group of spinning head (2), with the interval state be formed on the plate body (1), offer meter word groove (21) and through hole (22) on each spinning head (2), it is characterized in that: the width of described rice word groove (21) and the degree of depth respectively are 0.11-0.13mm.

2, the spinnerets of improvement structure according to claim 1 is characterized in that the width of described rice word groove (21) and the degree of depth respectively are 0.12mm.
