A kind of multiply multiple grinding industrial brush silk and manufacture method thereof
Technical field
The present invention relates to a kind of method of brushing silk and manufacturing this brush silk, be specifically related to a kind of multiply multiple grinding industrial brush silk and manufacture method thereof.By special process processing: be made up of grinding silk core and fiber top layer, grinding silk core is two and many abrasive filaments or polyamide monofilament composition, and fiber yarn is wrapped in grinding silk core outer surface composition fiber top layer.
Background technology
Polishing industry is used taking abrasive filaments and polyamide monofilament as main, its shape has rectilinear, also has wave (song) shape.Abrasive filaments is mainly grinding, is finished to master, and polyamide monofilament mainly cleaning, finishing is as main.Because abrasive filaments or polyamide monofilament are all that spinning forms, its diameter is all to be determined by extruder die panel aperture, and causing rhizoid toughness is from the beginning to the end all the same with bending strength and polishing dynamics.A kind of multiply provided by the invention is ground and is used industrial brush silk, because grinding silk core is fettered by fiber top layer, can resistance to compression keep wire body hardness when making when stressed after brush, and the multiply abrasive filaments of grinding silk core or polyamide monofilament are as individual combination, as broom, grinding, polishing and clean area are increased, anti-leak-stopping brush.
Summary of the invention
Primary technical problem to be solved by this invention is to provide the grinding silk core outer surface fiber yarn being made up of many abrasive filaments or polyamide monofilament and twines a kind of multiply multiple grinding industrial brush silk and the manufacture method thereof that combine bunchy.
The present invention is achieved through the following technical solutions:
A kind of multiply multiple grinding industrial brush silk, comprises multiply grinding silk core and is wrapped in the fiber top layer on grinding silk core outer surface; Grinding silk core is made up of at least two abrasive filaments or polyamide monofilament; Fiber top layer can be single or multiple lift.
Abrasive filaments or the polyamide monofilament of described grinding silk core composition, material is polyamide, polyester, polyolefin or polyurethane etc.; Grinding silk core quantity is 3,5 or 7, and quantity is preferably 3;
Fiber top layer is that the material of fiber yarn is a kind of Fypro, polyester fiber or polyolefine fiber etc., and the mixture that also can be polyolefine fiber such as Fypro or polyester fiber etc. is entwined at grinding silk core outer surface.
Abrasive filaments or the polyamide monofilament of described grinding silk core composition, material is polyamide, polyester, polyolefin or polyurethane etc.
If described grinding silk core composition abrasive filaments, abrasive grain used is selected from aluminium oxide, diamond, corundum, boron carbide, carborundum, cubic boron nitride, ceramic abrasive etc.Abrasive grain degree used is 12 order~3000 orders.
The fiber dimensious of fiber yarn was 50 dawn~500 dawn, and fiber yarn is wound in grinding silk core outer surface braiding and forms fiber top layer, and fiber yarn is wound around and can be once wound around or twice cross winding or repeatedly repeat to be wound around.
The fiber dimensious of fiber yarn was 100 dawn.
Multiply grinding silk core and the diameter range of industrial brush silk that is wrapped in fiber top layer on grinding silk core outer surface composition are at 0.2mm~10mm, in the majority with 0.50mm~2.0mm.
The combination on grinding silk core and fiber top layer can adopt adhesive bonding, and also can adopt and add the bonding of thermal fiber top layer and grinding silk core, or the mode that combines with heating of adhesive.
The manufacture method of industrial brush silk for multiply multiple grinding, its technique is:
Multiply grinding silk core remains a constant speed and advances, and fiber yarn is reeled and is wound to grinding silk core layer surface.Fiber yarn I and fiber yarn II are respectively to be wrapped in multiply grinding silk wicking surface with counterclockwise cross winding clockwise, common formation is wrapped in a fiber top layer for the outer surface that mill silk is sandwich layer, grinding silk core combination bunchy or fiber yarn are only clockwise or are counterclockwise wrapped in grinding silk core outer surface combination bunchy, or fiber yarn repeatedly repeats to be wound around by grinding silk core combination bunchy at grinding silk core outer surface.
Grinding silk core and the combination on fiber top layer can adopt the bonding or heating and melting of upper adhesive in conjunction with or the mode that combines with heating of adhesive.
Multiply multiple grinding of the present invention with industrial brush silk compared with existing abrasive filaments or polyamide monofilament, it is using abrasive filaments or polyamide monofilament as grinding silk core, fiber yarn handbag is overlayed on to the outer surface of grinding silk core, make superficial layer and the grinding silk core boundling of fitting completely.The present invention has promoted hardness and grinding intensity and the cleaning capacity of grinding silk core, because grinding silk core is fettered by fiber top layer, can resistance to compression keep wire body hardness when making when stressed after brush, and the multiply abrasive filaments of grinding silk core or polyamide monofilament are as individual combination, as broom, grinding, polishing and clean area are increased, anti-leak-stopping brush.
Brief description of the drawings
Fig. 1 is the structural representation of multiply multiple grinding of the present invention industrial brush silk.
Fig. 2 is the schematic diagram of multiply multiple grinding of the present invention industrial brush yarn production method.
In figure: the 1st, grinding silk core, the 2nd, fiber top layer, 2-1 is fiber yarn I, 2-2 is fiber yarn II.
Detailed description of the invention
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described.
As shown in Figure 1, a kind of multiply multiple grinding industrial brush silk, comprises grinding silk core 1 and fiber top layer 2.
Grinding silk core is abrasive filaments or polyamide monofilament, and quantity is preferably 3, or is preferably 5, or is preferably 7.Present case grinding silk silk core is abrasive filaments, and quantity is 3.
Described multiply multiple grinding with the manufacturing process of industrial brush silk as shown in Figure 2, fiber yarn is using Polyamide Yarns as example: get that 3 abrasive filaments compositions are a branch of to remain a constant speed and advance as grinding silk core 1, fiber yarn is wound to 1 layer of surface of grinding silk core.Fiber yarn I2-1 and fiber yarn II2-2 respectively with clockwise with cross winding counterclockwise on multiply abrasive filaments core 1 surface, when winding, keep tension force, common formation is wrapped in the fiber top layer 2 on the outer surface that grinding silk 1 is sandwich layer, by grinding silk core combination bunchy.Can repeat on grinding silk core 1 surface to be wound around, make fiber top layer 2 form at least two-layer sandwich construction.Fiber yarn I2-1 and fiber yarn II2-2 keep suitable tension force while winding, multiply grinding silk core combination bunchy.
Grinding silk core 1 can adopt adhesive bonding with the combination on fiber top layer 2, and also can adopt and add the bonding of thermal fiber top layer and grinding silk core, or the mode that combines with heating of adhesive.Present case adopts drips the mutual adhesion of fiber on the monolateral gluing use of glue fiber top layer and sticks on grinding silk core.
Above-described embodiment is only preferred embodiment of the present invention, and all equivalences of doing according to structure of the present invention, shape, principle change, within all should being covered by protection scope of the present invention.
