Abstract
The utility model relates to a spinneret plate for seven-pore three-dimensional crimped fiber; spinneret holes [1] on a spinneret plate [2] are distributed in an annular shape; the spinneret holes [1] are composed of guide holes [3] and spinneret pores [4]. The utility model is characterized in that the cross-sectional shapes of the spinneret pore [4] are composed of six C-shaped holes [5] which are arranged in an annular shape. 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
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 difficulty of processing of spinnerets is higher in addition, makes that the cost of spinnerets is very high, and service life is not long yet.
The purpose of this utility model is to provide a kind of seven apertures in the human head 3 D stereo crimped fibre spinnerets of making the good fiber of compression resilience.
The technical solution of the utility model is: the utility model is a seven apertures in the human head 3 D stereo crimped fibre spinnerets, 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 made up of six C shape holes, and arrange in the form of a ring in these six C shape holes.
The utility model compared with prior art has following advantage:
After the technical program, can be made into the seven apertures in the human head fiber.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 is can be at opening part closed or form blind bore with adjacent hole wall adhesion, make a fiber six isolated holes be arranged along circumference, and the central portion of spinnerets does not have the hole, make to form a hole again after interior half of binding of six hole walls, totally seven holes.Like this, the warmth retention property of fiber and resilience are all better, owing to be C shape hole, so the technological requirement of processing spinnerets is low, the intensity of spinnerets is also better simultaneously.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:

Embodiment: the utility model is a kind of seven apertures in the human head 3 D stereo crimped fibre 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], it is characterized in that: the cross sectional shape of described spray silk pore [4] is made up of six C shape holes [5], and arrange in the form of a ring in these six C shape holes [5].Referring to accompanying drawing 3, comprise an adjacent C shape hole [5] in the C shape hole opening [6] in described C shape hole [5], when high polymer sprays from C shape hole [5], the hole wall adhesion in the fiber hole wall of C shape hole opening part and adjacent C shape hole; The C shape hole of this big opening has the low advantage of technological requirement of processing spinnerets, and the technological requirement of processing fiber is not high yet.Referring to accompanying drawing 4, this is a kind of C shape hole spinnerets of little opening, and the high polymer of ejection is in the opening part adhesion, and spinnerets is easy to process, but compares with the structure shown in the accompanying drawing 3, and the high polymer that comes out in C shape hole is difficult in the opening part adhesion.Referring to accompanying drawing 5, have C shape hole knuckle [7] on the described C shape hole [5], the high polymer that sprays from this hole is because the tension force of knuckle is big, so high polymer is located the high polymer adhesion mutually that is easy to come out with adjacent C shape hole at C shape hole opening [6].Referring to accompanying drawing 6, described adjacent C shape hole [5] part overlaid is connected adjacent C shape hole [5].C shape hole opening [6] on the described C shape hole [5] is outside, and also there is open communication [8] inboard in each C shape hole [5].The high polymer that sprays in such C shape hole is located and open communication [8] is located the adhesion closure at C shape hole opening [6], forms the seven apertures in the human head fiber, the spinnerets intensity height of this structure, and the technological requirement of processing fiber is simple.
