Abstract
The invention relates to a method for producing colored hollow flame retarding polyester short fibers, which is characterized in that uniquely-designed spinneret plates are used for production according to the chip spinning production process, and color master batches and flame retarding master batches are added into melt by a side pouring mode respectively; and the section of produced fiber is changed into a ring shape with gaps from the prior circular hole, and the number of the gaps is generally three, or four or more than four as required. Because the spinneret plates with non-conventional design are adopted, and the shape of the section of the fiber produced by using the spinneret plates is different from that of general colored hollow terylene short fibers. The difference greatly deepens the product colority so as to reduce the usage of the master batches, and is favorable for the melt of the flame retarding master batches and the chips, thereby reducing production cost to the maximum extent and improving the product quality. As the product has multiple functions or characteristics such as colorfulness, hollowness and flame retard, the application range is greatly widened, and the added value of the product is substantially improved.
Description
Technical field
The present invention relates to a kind of polyester staple fibers, particularly a kind of coloured hollow also has the polyester staple fibers and the production method thereof of anti-flaming function, belongs to the chemical fibre production technical field.
Background technology
The cross section of general coloured hollow short dacron fiber is circle or irregular cycle, and its outer edge is smooth, regular.This architectural feature causes fiber under the reflection of light effect, and color can form diffuse reflection clocklike, thereby causes fiber colourity to shoal or not bright-coloured, and especially the fiber surface that those colors are single is all the more so.In actual production, have to satisfy the requirement of colourity, thereby production cost is improved with the method that increases the Masterbatch consumption.
In addition, therefore the flame-resistant terylene short fiber generally has only single anti-flaming function fiber product to occur owing to added the fire retardant (phosphorus system or halogenated flame retardant) that influences the spinning ordinary production in spinning process.If be used for adding the anti-flaming function master batch again in the coloured spinning process flow process of hollow, may cause production cost to rise, product quality or correlation function occur unusual.
Summary of the invention
The object of the present invention is to provide a kind of coloured hollow polyester staple fibers and production method thereof with anti-flaming function.
The technical scheme that the present invention takes is: the spinnerets that uses unique design, spinning production process by section produces, Masterbatch and fire-retardant master granule join in the melt in the sidenote mode respectively, additional proportion accounts for 0.5～1.5% and 0.3～1.2% of spinning melt, specifically requires with the colourity of required product and fire resistance and decides.
In the described technical scheme, the carrier of two kinds of master batches is PET.
In the described technical scheme, Design of spinneret has guaranteed to become a kind of notched annular with the fibre section of its production by traditional circle hole shape, and this breach is generally 3, also can be as required 4 and more than.
In the described technical scheme, fiber dimensious is (1.11dtex～2.22dtex) * (38～51mm).
In the described technical scheme, it is identical that production procedure is spun in the main production process of spinning and common section.
The invention has the beneficial effects as follows: owing to adopted the spinnerets of unconventional design, fiber section configuration with its production is different with general coloured hollow short dacron fiber, thereby this difference has been deepened product colourity greatly and has been reduced the Masterbatch consumption, help the fusion of fire-retardant master granule and section simultaneously, thereby amplitude peak reduces production costs, and improves the quality of products.
Product degree of hollowness of the present invention can reach more than 35%, compare saving Masterbatch consumption 20% with conventional method, the product fire resistance is fine, be spun into yarn and the fabrics flame resistance oxygen index (OI) that is made into can reach 20～35% with it, by becoming the black carbide after the flame burning more than 200 ℃, no flame and molten drop phenomenon, can keep original state, indeformable, do not break, thereby absorb heat, play burning, the effect of knock down the flame automatically of stoping.This product is owing to have coloured, hollow, multiple function or proterties such as fire-retardant, and the scope of application increases greatly, and added value of product improves greatly, can be used as the textile raw material of every field such as clothes, family spin, decoration.
Description of drawings
Fig. 1 is the cross sectional shape schematic diagram of spinnerets hole shape of the present invention, and wherein 1 is annulus, and 2 is the breach between annulus.
The specific embodiment
Specifically tell about embodiments of the invention below in conjunction with accompanying drawing.
Spinning on German Ba Mage spinning machine, pump are for amount 745g/min, and the rich speed of volume is 1050m/min, and spinning temperature is 290 ℃, and spinnerets adopts 960 holes.In Beijing, carry out drawing-off, 4 times of drafting multiples, 125 ℃ of drawing temperatures on the beautiful LHV3 type associating drawing machine then.Masterbatch and flame-retardant master batch melt extrude the back through separately small screw and are injected in the melt static mixer in 0.8% ratio of total melt quality, fully mix with the PET melt and to carry out spinning, the main technological process of production is: drying → spinning → coiling → moulding → boundling → drawing-off → curl → cut off.Hole shape obtains specification 1.67dtex * 38mm product as shown in Figure 1 at last on the spinnerets, and product cross section is the hollow shape with annulus formation of 3 breach, degree of hollowness 35%.
The product degree of hollowness that present embodiment is produced is higher, owing to have the cavity of larger volume, makes and is rich in the air that does not produce convection current in the fiber, thereby produce heat-preserving function, encases warm air, and isolates with cool ambient air, keeps body temp.Simultaneously, reduce the Masterbatch consumption, help the fusion of fire-retardant master granule and section simultaneously, thereby amplitude peak reduces production costs, and improves the quality of products thereby deepened product colourity greatly.The product fire resistance is fine, and this product is owing to have coloured, hollow, multiple function or proterties such as fire-retardant, and the scope of application increases greatly, can be widely used in every field such as clothes, family spin, decoration.
