Abstract
The present invention relates to a rubber diaphragm warp and weft homogeneous cloth of a vehicle braking air chamber and a manufacture method of the rubber diaphragm warp and weft homogeneous cloth, particularly to a reprocessing finished product of filament products in chemical fiber industry and a manufacture method of the reprocessing finished product. The warp and weft homogeneous cloth is partitioned by technology cloth through gum dipping processing to eliminate wefts which are partitioned by the technology cloth through gum dipping processing, and the warps are wound on a cylinder; pirns are formed after weft winding is put into a weaving shuttle; the second weaving on a weaving machine is carried out according to the structure requirements of the fabric density of the warp and weft homogeneous cloth to manufacture the warp and weft homogeneous cloth.
Description
What warp and weft homogeneous cloth for rubber diaphragm of braking air chamber in car of the present invention and manufacture method thereof related to is a kind of manufactured goods of processing again and manufacture method thereof of chemical fibre industry long filament goods, particularly the parallel of warp-weft same-nature fabric is to carry out the branch watchman's clapper with the technology cloth of handling through impregnation, its warp is twined tube earlier, carry out again coming into operation after the quilling, carry out secondary and weave.
At present, the framework material of domestic production rubber diaphragm of automobile brake chamber all adopts synthetic fiber to weave and forms, and its weak point is if keep the longitude and latitude of fabric identical to performance, then the poor adhesion of itself and rubber; Fabric is carried out the bond properties that surface treatment changes itself and rubber, because of fabric in surface treatment process, fabric is subjected to the different influence of tension force through broadwise, and fabric is through ultimate strength, elongation at break, the percent thermal shrinkage difference of broadwise, and influences the physical property of final products.
The objective of the invention is provides a kind of warp and weft homogeneous cloth for rubber diaphragm of braking air chamber in car and manufacture method thereof at above-mentioned weak point, both changed the cohesiveness of chemical fibre industry filament yarn fabric and rubber, keep the longitude and latitude of chemical fibre industry filament yarn fabric identical again, thereby guarantee the premium properties of rubber diaphragm of automobile brake chamber and other rubbers to performance (ultimate strength, elongation at break, percent thermal shrinkage).
Warp and weft homogeneous cloth for rubber diaphragm of braking air chamber in car and manufacture method thereof take following scheme to realize: the warp-weft same-nature fabric feature is that the warp-weft same-nature fabric warp is to break with the technology cloth of handling through impregnation (cord fabric), removes parallel; Parallel is to break with the technology cloth of handling through impregnation (cord fabric), and its warp is twined tube earlier, carries out quilling again and becomes cop to put into to knit shuttle, is undertaken weaving the second time by warp-weft same-nature fabric Density structural requirement forming on loom.
The warp and weft homogeneous cloth for rubber diaphragm of braking air chamber in car manufacture method is: according to the technical indicator of warp-weft same-nature fabric and the total quantity of warps of fabric width requirement design warp-weft same-nature fabric, chemical fibre industry long filament after the twisting is made warp, and cotton thread or other blended yarns are made into technology cloth (cord fabric) as parallel.The chemical fibre industry long filament can adopt continuous synthetic fibre (nylon) long filament, polyester filament etc.
Technology cloth after weaving is carried out impregnation (going up sizing material) on cement dipping machine, drying is handled, bake out temperature is at 110 ℃～150 ℃, drawing and setting heat treatment, draft temperature is at 190 ℃～243 ℃, tensile stress is at 300kg～1000kg, and setting temperature is at 190 ℃～243 ℃, and typing tension force is at 250kg～800kg.With bonding force and its physical property of control that improves chemical fibre and rubber.
To break through the technology cloth that impregnation was handled, after partition, carry out secondary again and weave.Wherein the warp of warp-weft same-nature fabric is weaved in partition, in the warp let-off plate of loading onto loom through impregnation process of thermal treatment cloth two ends, wear long and load onto the cloth machine behind the palm fibre, before weaving cotton cloth, technology cloth parallel is cut off it with many blades earlier, use hairbrush (bristle brush wheel) that technology cloth parallel is removed again; The parallel of partition warp-weft same-nature fabric, the technology cloth that adopts above-mentioned same process method to handle through impregnation breaks, twine tube earlier with its warp, carry out quilling again and become cop, put into and knit shuttle, Density structural requirement by warp-weft same-nature fabric on loom carries out weaving the second time, promptly makes warp-weft same-nature fabric.
Sizing material can adopt a first emulsion (RFL sizing material), first emulsion+sizing materials such as RP adhesive.
Between first emulsion proportioning raw materials (percentage by weight): fourth pyrrole latex 28～29%, natural emulsion 4.2～4.6%, resorcinol 1.5～1.8%, formaldehyde 2.2～2.5%, liquid caustic soda 0.4～0.5%, soft water surplus.By proportioning difference weighing above-mentioned raw materials, put into agitator when sizing material is made, make through mixing.
Between first emulsion+RP binder materials proportioning (percentage by weight), fourth pyrrole latex 24～25%, resorcinol 1.5～1.7%, formaldehyde 1.4～1.6%, RP adhesive 40～42%, liquid caustic soda 0.3～0.4%, soft water surplus.When sizing material is made by proportioning respectively the weighing above-mentioned raw materials put into agitator, make through mixing.
Warp and weft homogeneous cloth for rubber diaphragm of braking air chamber in car manufacture craft uniqueness, the good effect that the warp-weft same-nature fabric that adopts manufacture method of the present invention to weave out has is: (1) fabric and rubber have good bonding force (bonding force 〉=8N/mm); (2). being consistent of fabric through broadwise brisement brute force, elongation at break and percent thermal shrinkage; (3). guaranteed all making full use of of even fiber strength of fabric bearing capacity.
The warp and weft homogeneous cloth for rubber diaphragm of braking air chamber in car that the invention method is made can be used as the framework material of rubber diaphragm of automobile brake chamber, also can be used as needs the rubber of warp-weft same-nature to make framework material, the framework material that adopts warp-weft same-nature fabric of the present invention to make rubber diaphragm of automobile brake chamber can improve the impact resistance and the fatigue performance of product, improves the security and the service life of braking automobile.
