Abstract
An electrically conductive organic fibre is composed of organic fibre and electrically conductive substance which is insymmetrically distributed in organic fibre. Its advantages are permanent curling, antistatic function and low cost.
Description
The present invention relates to a kind of conductive fiber, refer to a kind of electrically conductive organic fibre especially, belong to the functional fiber field with special cross-section structure.
The conventional fibre material belongs to insulator more, often uses in weaving, clothes processing.Because this fibrous material very easily produces static, cause electrostatic interference, and influence the safety of microelectronic component, so the electrically conductive organic fibre of making in the compound mode of the conduction component that contains conductive materials and conventional high polymer occurred.Electrically conductive organic fibre has good antistatic performance, and effect is lasting.It is added in the common textile material, can make textiles have anlistatig effect.
Electrically conductive organic fibre mostly is composite construction, and its section morphology comprises following three types: 1: cortex is the core-sheath composite structure conductive fiber of conductive component.2: the equally distributed fabric of island-in-sea type composite construction of multiple spot conductive component conductive fiber.3: the composite construction conductive fiber that conductive component distributes symmetrically and evenly with sheet or cruciformity.The common feature of the electrically conductive organic fibre of the above three kinds of structure is: conductive component is to distribute symmetrically in fiber.Its shortcoming is: though common high polymer and the conductive component that contains conductive materials on thermal contraction performance and bending rigidity, have than big-difference,, because conductive component distributes in fiber symmetrically, cause the whole stiff nothing of fiber to be curled, textile processibility can be poor; And be compound to when going in the common yarn, the distribution of conductive fiber in yarn do not have tendentiousness, and conductive component is difficult to all be aligned to yam surface, thereby reduced the antistatic property of conductive materials.
In view of the foregoing, the purpose of this invention is to provide a kind of electrically conductive organic fibre of new special cross-section structure, this electrically conductive organic fibre can permanently curl, and antistatic effect is good, and antistatic property is lasting, intrastitial conductive component non-uniform Distribution.
For achieving the above object, the present invention takes following design: this electrically conductive organic fibre, it is composited by organic fiber and conductive materials, it is characterized in that: described conductive materials is non-homogeneous and is distributed in the fiber symmetrically, side at fiber has a plurality of conductive materials, does not have conductive materials at the opposite side of fiber.
Because the present invention adopts above design, the conductive component that will contain conductive materials is distributed on the fibre section in mode heterogeneous, and a side has more conductiving point, and opposite side does not have conductiving point.The existence of one side of conductiving point because of the rigid conductive material arranged, percent thermal shrinkage is low, bending rigidity is high, and no conductiving point one side is because of the existence of no rigid conductive material, and percent thermal shrinkage height, bending rigidity are low, so composite fibre can permanently curl, conductiving point is in the curling outside.After the weaving processing, these conductiving points are in the surface of yarn and fabric automatically, can bring into play the effect of converging electric charge, loss electric charge, reach the purpose of eliminating static.In addition, the present invention has also improved the utilization ratio of expensive conductive component, under identical conductive component content, has avoided conductive component to be in the inside of yarn or fabric, can not give full play to its antistatic property.And, because the permanent curl characteristics of fiber that the structure of conductive materials non-homogeneous symmetrical distribution in fiber forms, improved the spinning performance of electrically conductive organic fibre.
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention.
As shown in Figure 1, the present invention is a matrix 1 with polyamide fibre 6, is that conductive materials 2 is made electrically conductive organic fibre with the carbon black.In manufacturing process, by adjusting the relative position of conductive component spinning fine duct in thick conduit in the composite spinneret pack, make each conductive component concentrate a side that is distributed in composite fibre, and with the tangent or rare exposure of the outline in composite fibre cross section.Make conductive component be non-homogeneous symmetrical distribution on the cross section of fiber, the side in the fibre section has a plurality of conductiving points, and opposite side does not have conductiving point.
Fibrous matrix of the present invention can be a polyamide fibre 6, also can be polyamide fibre 66, terylene or polypropylene fibre; Conductive materials can be a carbon black, also can be metallic compound.
Below, be that conductive materials, polyamide fibre 6 are matrix with the carbon black, organic composite conducting fiber of 3 one-sided distributions of conductiving point is a sample 1; Equally, be that conductive materials, polyamide fibre 6 are matrix with the carbon black, 3 equally distributed organic composite conducting fibers of conductiving point are sample 2, relatively their surface density of charge.Two kinds of composite conducting fibers are knitted with in a kind of pure dacron along the warp-wise embedding with the 2cm spacing, and the surface density of charge of fabric is as follows:
| Sample | Electric charge minuteness degree (mean value), μ c/m 2 |
| Sample 1: the fabric of the one-sided distribution of conductiving point | ????1.3 |
| Sample 2: the equally distributed fabric of conductiving point | ????2.4 |
| Sample 3: the blank fabric of no conductive fiber | ????10.4 |
Advantage of the present invention is: 1: utilize the percent thermal shrinkage difference and the bending rigidity difference of one-sided concentrated distribution, conductive component and the common high polymer of conductive component in composite fibre, composite fibre is produced curl.In the outside of curling more conductiving point is arranged,, make conductiving point be in the surface of fabric, give full play to the effect of conductive materials loss electrostatic charge, reach better antistatic effect through weaving processing; And improve the weavability of electrically conductive organic fibre.2: under identical conductive materials addition, better antistatic effect is arranged; Under identical antistatic property requires, can reduce the consumption of conductive component, reduce cost.3: can be adapted to the production system of existing composite construction conductive fiber, except that the structure of needs adjustment or change spinning pack, not need to update the equipment.
The above only is preferred embodiment of the present invention, and any equivalent transformation based on technical solution of the present invention all belongs within the protection domain of the present invention.
