Abstract
The utility model discloses a kind of filter bag sewing thread, including PTFE long filaments and PPS spun yarns, the outer surface that the PPS spun yarns are wrapped in the PTFE long filaments forms covering yarn structure.The PTFE long filaments use 1200D PTFE yarns；The PPS spun yarns use the PPS yarns of 12s sub-threads.Filter bag sewing thread of the present utility model, PPS spun yarns have very many filoplumes, these filoplumes for being coated on the PPS spun yarns of PTFE filament surfaces serve the effect of closure pin hole, follow-up pin hole need not be handled just preferably can avoid fine dust from penetrating pin hole, so as to realize minimum discharge.
Description
Technical field
The utility model is related to a kind of filter bag sewing thread.
Background technology
Conventional high temperature filtration sack is during being sewed, since it is considered that resistant to elevated temperatures characteristic, it will usually select
PTFE (polytetrafluoroethylene (PTFE)) sewing thread is sewed.PTFE sewing threads have very excellent high temperature resistant, and resistance to is chemically, simultaneously
Due to PTFE or particularly preferred friction material, the characteristics of with unusual light.
Referring to Fig. 1, traditional smooth PTFE sewing threads 1' is after sewing filtering bag 2', pin hole 3' can have hole
Gap, this hole is easy for allowing fine dust to penetrate, so that minimum discharge difficult to realize.
Current product mainly relies on later process in pin hole position gluing for the closure of pin hole or utilizes adhesion
Material is covered, and such processing technology can additionally increase by a procedure.And handle and focus primarily upon surface treatment, once this layer of material
Material is destroyed, and original pin hole can be exposed, and can not then realize the control for discharge.
Utility model content
The purpose of this utility model be the defect for overcoming prior art there is provided a kind of filter bag sewing thread, pin hole can be carried out
Closure, preferably can avoid fine dust from penetrating pin hole, so as to realize minimum discharge.
Realizing the technical scheme of above-mentioned purpose is：A kind of filter bag sewing thread, including PTFE (polytetrafluoroethylene (PTFE)) long filaments and PPS
(polyphenylene sulfide) spun yarn, the outer surface that the PPS spun yarns are wrapped in the PTFE long filaments forms covering yarn structure.
A kind of above-mentioned filter bag sewing thread, wherein, the PTFE long filaments use 1200D PTFE yarns；The short fibres of PPS
Yarn uses the PPS yarns of 12s sub-threads
Filter bag sewing thread of the present utility model, PPS spun yarns have very many filoplumes, and these are coated on the long silk tables of PTFE
The filoplume of the PPS spun yarns in face serves the effect of closure pin hole, it is not necessary to which follow-up handled pin hole just can be more preferable
Fine dust is avoided to penetrate pin hole, so as to realize minimum discharge.
Brief description of the drawings
Fig. 1 is the use state figure of traditional PTFE sewing threads；
Fig. 2 is the structural representation of filter bag sewing thread of the present utility model；
Fig. 3 is the use state figure of filter bag sewing thread of the present utility model.
Embodiment
In order that those skilled in the art are better understood when the technical solution of the utility model, with reference to attached
Its embodiment is described in detail figure：
Referring to Fig. 2, most preferred embodiment of the present utility model, a kind of filter bag sewing thread 1, including PTFE long filaments 11 and PPS
Spun yarn 12, the outer surface that PPS spun yarns 12 are wrapped in PTFE long filaments 11 forms covering yarn structure.
PTFE long filaments 11 use 1200D PTFE yarns；PPS spun yarns 12 use the PPS yarns of 12s sub-threads.Selection
The PPS yarns of 1200D PTFE yarn combination 12s sub-threads, the PTFE yarns of this fineness can fully ensure that the strong of sewing thread
Power, in the case that the PPS yarns of this thickness may insure that the pin of sewing filtering bag does not change, it is possible to use its filoplume will
Pin hole is blocked.
Referring to Fig. 3, filter bag sewing thread 1 of the present utility model, in sewing filtering bag 2, PPS spun yarns have very many
Filoplume, these filoplumes for being coated on the PPS spun yarns of PTFE filament surfaces serve the effect of closure pin hole 3, it is not necessary to follow-up
Pin hole, which is handled, just preferably can avoid fine dust from penetrating pin hole, so as to realize minimum discharge.And because PPS is fine
Dimension is also that, with resistant to elevated temperatures characteristic, this sewing thread can be used well in the product of some PPS and PTFE blending.
In summary, filter bag sewing thread of the present utility model, on the one hand by process reduction together, substantially increases processing
Efficiency, while using the effect of covering yarn, pin hole block to realize no dust leakage, the ultralow row of country is tackled
Put and more outstanding product is provided.In addition, the characteristics of material equally has extraordinary resistance to gentle resistant to chemical etching, Ke Yi
Used in many applications.
Those of ordinary skill in the art is it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new
Type, and be not used as limiting of the present utility model, as long as in spirit of the present utility model, to described above
Change, the modification of embodiment will all fall in Claims scope of the present utility model.
Claims (2)
1. a kind of filter bag sewing thread, it is characterised in that including PTFE long filaments and PPS spun yarns, the PPS spun yarns are wrapped in institute
The outer surface for stating PTFE long filaments forms covering yarn structure.
2. a kind of filter bag sewing thread according to claim 1, it is characterised in that the PTFE long filaments are using 1200D's
PTFE yarns；The PPS spun yarns use the PPS yarns of 12s sub-threads.
