Abstract
The utility model provides inflaming retarding polyester filament which comprises a polyester filament body. The polyester filament body is a filament bundle formed by a plurality of pieces of monofilament, an inflaming retarding layer is covered on the surface of the monofilament, and the cross section of the monofilament is in a Y shape. After the technical scheme is adopted, the inflaming retarding layer is covered on the surface of the monofilament. Accordingly, the surface of each piece of monofilament can block open fire through the inflaming retarding layer when the polyester filament meets fire, thereby enabling the polyester filament to have the inflaming retarding effect. Simultaneously, the cross section of the monofilament is in the Y shape. Accordingly, contraction is easily generated when the monofilament meets the open fire, the whole polyester filament is contracted, and the effects of heat insulation and oxygen insulation are achieved, thereby further improving the inflaming retarding effect of the polyester filament.
Description
Technical field
The utility model relates to the chemical fibre field, particularly a kind of polyester filament.
Background technology
Terylene is a kind of synthetic fiber with fastest developing speed in the various synthetic fiber, that output is the highest, application surface is the widest, and it is widely used in fiber textiles such as clothes, curtain, carpet, bedding, interior decoration.Yet the limited oxygen index of traditional terylene is about 21, and limited oxygen index＜22 belong to combustible material,, along with the extensive use of polyster fibre, the potential danger of its fire also increases day by day.
In view of this, the inventor furthers investigate polyester filament, and this case produces thus.
The utility model content
The purpose of the utility model is to provide a kind of fire-retardant polyester filament yarn with anti-flaming effect.
The technical scheme that the utility model adopted is such: a kind of fire-retardant polyester filament yarn, comprise the polyester filament body, and this polyester filament body is the tow of being made up of some monofilament; The surface coverage of above-mentioned monofilament has flame-retardant layer, and the shape of cross section of above-mentioned monofilament is a Y shape.
Above-mentioned flame-retardant layer is the black flame-retardant layer.
After adopting technique scheme, a kind of fire-retardant polyester filament yarn of the utility model is because the surface coverage of monofilament has flame-retardant layer; Like this, obstructing capacity can be played to naked light in the surface of each monofilament when making polyester filament meet fire through this flame-retardant layer, makes polyester filament have flame retardant effect; Simultaneously, the shape of cross section of monofilament is a Y shape, and monofilament is easy to generate contraction when running into naked light like this; Polyester filament integral body is tightened up, play effect heat insulation, oxygen barrier, thereby further improve the flame retardant effect of polyester filament; Again because flame-retardant layer is the black flame-retardant layer; Like this; Through this flame-retardant layer polyester filament is had outside the flame retardant effect; Also make polyester filament form the polyester filament of black, saved the later stage dyeing process of polyester filament, avoided causing environmental pollution problems because of the later stage dyeing process of polyester filament.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure:
Black flame-retardant layer 2
The specific embodiment
A kind of fire-retardant polyester filament yarn of the utility model; As shown in Figure 1, comprise polyester filament body 1, the tow of this polyester filament body 1 for twisting into by some monofilament 11; The cross section of this tow is a square; The shape of cross section of this monofilament 11 is a Y shape, and these monofilament 11 surfaces coated are covered with black flame-retardant layer 2, the amalgam layer of this black flame-retardant layer 2 for being mixed by carbon black and phosphorus flame retardant.
After adopting technique scheme, a kind of fire-retardant polyester filament yarn of the utility model is because the surface coverage of monofilament 11 has flame-retardant layer 2; Like this, obstructing capacity can be played to naked light in the surface of each monofilament 11 when making polyester filament meet fire through this flame-retardant layer 2, makes polyester filament have flame retardant effect; Simultaneously; The shape of cross section of monofilament 11 is a Y shape, and monofilament 11 is easy to generate contraction when running into naked light like this, and polyester filament integral body is tightened up; Play effect heat insulation, oxygen barrier, thereby further improve the flame retardant effect of polyester filament; Again because black flame-retardant layer 2 is what mixed by carbon black and phosphorus flame retardant; Like this; Through this flame-retardant layer 2 polyester filament is had outside the flame retardant effect; Also make polyester filament form the polyester filament of black, saved the later stage dyeing process of polyester filament, avoided causing environmental pollution problems because of the later stage dyeing process of polyester filament.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
Claims (2)
1. a fire-retardant polyester filament yarn comprises the polyester filament body, and this polyester filament body is the tow of being made up of some monofilament; It is characterized in that: the surface coverage of above-mentioned monofilament has flame-retardant layer, and the shape of cross section of above-mentioned monofilament is a Y shape.
2. a kind of fire-retardant polyester filament yarn according to claim 1 is characterized in that: above-mentioned flame-retardant layer is the black flame-retardant layer.
