Abstract

The utility model relates to a spinning plate used for spinning porous three-dimensional crimped fiber. Spinning holes [1] on a spinning plate [2] are distributed in an annular shape, and the spinning holes are composed of guide holes [3] and spinning pores [4]. The utility model is characterized in that the cross-sectional shapes of the spinning pores [4] are formed by that C-shaped holes [7]are arranged at the center; a plurality of T-shaped holes are surrounded and ranged out of the C-shaped holes [7]; the cross holes of each T-shaped hole are arranged at the outer side; the vertical holes of the T-shaped holes are arranged at the inner side, and point to the C-shaped holes [7]. The utility model has simple machining, and is convenient for the adhesion of each hole wall, causing fiber has good heat insulating ability and resilience.

Description

Spinning porous three-dimensional stereo crimped fiber spinnerets

The utility model relates to a kind of spinnerets that chemical fibre is used that spins.

In the prior art, Patent Office of the People's Republic of China announced the utility model patent that name is called " high degree of hollowness 3 D stereo crimped fibre spinnerets " (patent No. 92244356.4) on October 13rd, 1993, its spinneret orifice cross sectional shape is that concentric single radial cut is circular, be also referred to as the C font, hole in the middle of made doughnut has only is because its degree of hollowness is up to 25%-35%, after making quilted bedding or pillow, pressurized flattens easily, bulkiness variation after use a period of time, and warmth retention property is the phase strain differential also.

The purpose of this utility model is to provide a kind of spinning porous three-dimensional stereo crimped fiber spinnerets of making the good fiber of compression resilience.

The technical solution of the utility model is: the spinneret orifice on the spinnerets distributes in the form of a ring, spinneret orifice is made up of guide hole and spray silk pore, the cross sectional shape of described spray silk pore is that central authorities are C shape hole, outside C shape hole around being arranged with a plurality of T shapes hole, the cross-drilled hole in described each T shape hole is in the outside, and the vertical core in T shape hole is in the inboard and point to C shape hole.

The utility model compared with prior art has following advantage:

After the technical program, can be made into a central hole, the fiber of porous arranged on every side, when from spinneret orifice, spraying as fine high polymer, because the tension force effect of Polymer Surface, the chemical fibre that comes out in C shape hole can be at the closed blind bore that forms of opening part, also interconnect between the cross-drilled hole in the adjacent T shape hole in the outside, and the vertical core inner end in T shape hole also is connected with C shape hole, make a fiber that a plurality of isolated holes be arranged, the warmth retention property of fiber and resilience are all better, the technological requirement of processing spinnerets simultaneously is low, and the intensity of spinnerets is also better.Compare with the worker's shape hole in the documents, more can guarantee the adhesion of the fiber of adjacent holes, make between each hole not to be communicated with.

The utility model will be further described below in conjunction with drawings and Examples:

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the A-A direction cutaway view (amplifying the back) of accompanying drawing 1;

Accompanying drawing 3 be a kind of embodiment the B-B of accompanying drawing 2 direction cutaway view (amplify back);

Accompanying drawing 4 be another kind of embodiment the B-B of accompanying drawing 2 direction cutaway view (amplify back); Wherein:

[1]. spinneret orifice; [2]. spinnerets; [3]. guide hole; [4]. spray silk pore; [5] .T shape hole cross-drilled hole; [6] .T shape hole vertical core; [7] .C shape hole;

Embodiment: referring to accompanying drawing, the utility model is a kind of spinning porous three-dimensional stereo crimped fiber spinnerets, spinneret orifice [1] on the spinnerets [2] distributes in the form of a ring, spinneret orifice [1] is made up of guide hole [3] and spray silk pore [4], the cross sectional shape of described spray silk pore [4] is that central authorities are C shape hole [7], around being arranged with a plurality of T shapes hole, the cross-drilled hole in described each T shape hole is in the outside outside C shape hole [7], and the vertical core in T shape hole is in the inboard and point to C shape hole [7].Relation between described T shape hole and the C shape hole can have two embodiment (seeing accompanying drawing 3 and accompanying drawing 4), in the accompanying drawing 4, the vertical core in described T shape hole cuts off mutually with C shape hole, this structure can be made into the above spinnerets in every fiber 5 holes, the mechanical strength height of spinnerets, the technology of processing spinnerets is convenient, after the high polymer of liquid sprays from spinneret orifice, rely on the tension force of Polymer Surface, the high polymer that comes out of the cross-drilled hole in adjacent T shape hole is inter-adhesive, the high polymer adhesion of coming out in the high polymer that the vertical core in T shape hole comes out and C shape hole mutually, the high polymer that comes out in C shape hole forms seven holes that are not connected in the adhesion of C shape opening part.In the accompanying drawing 3, the vertical core in described T shape hole is connected with C shape hole, and it can guarantee the bonding rate in the hole of fiber, and is low to the processing technology requirement of fiber, but the intensity of spinnerets is slightly poor, makes a farfetched comparison Fig. 4 outline weak point service life.
