Abstract
The utility model relates to a crisscross ECDP (easy cationic dyeable polyester)/PET (polyethylene terephthalate) compound flame-retardant fiber. Flame-retardant masterbatch, ECDP slices and PET slices are evenly mixed at first; spinning is carried out by adopting the melt spinning technology; filament yarns are processed through bundling, drawing and two-dimensional or three-dimensional helical curling, and then is cut into fibers into needed specifications; a spinneret plate adopts a crisscross spinneret plate; the cross section of the fibers is in the shape of a cross; the length(a)-width(b) ratio of the fibers is 5:3; and the denier count of the fibers ranges from 0.5 to 5 denier. The crisscross ECDP/PET compound flame-retardant fiber has the advantages as follows: the technological process is simple, the production can be carried out on the original equipment, and the benefits are improved; and the product versatility can be achieved.
Description
[technical field]
The utility model relates to the functional fibre technical field, specifically, is a kind of cross ECDP/PET composite flame-proof fiber.
[background technology]
At present, PET industry from 21 century production capacity sharply increase, present domestic polyester production capacity is above 2,000 ten thousand tons/year, but the utilization of capacity is very low, cost of material height, added value of product are hanged down and are caused many reasons such as the finished product price is low to cause numerous polyester losses of enterprise serious, the stop device of much having to close, in this case, Development and Production high added value functional polyester product, energy saving and cost lowering become the theme of numerous enterprises Future Development.On the other hand, along with the raising of social life level, people are more and more higher to the requirement of clothing comfortableness, and progress of science and technology also provides possibility for the improvement of comfort of fabric energy.
Polyester fiber is the first kind of synthetic fiber, and its output accounts for more than 80% of chemical fibre total output, because of its good cost performance is widely used in garment material and other non-field of taking.Yet the functional polyalkylene ester fiber becomes people's research focus, thereby improves the added value of traditional fibre.
Contain the sulfonic acid group that strong affinity is arranged with cation dyes in the ECDP fibre structure, available cation dyes are carried out boiling dyeing at normal pressure, dye-uptake and dye exhausting rate height.Dyed fiber and fabric color is bright-coloured, chromatogram is complete, and have that good soap dyes, washing, friction, light fastness, the anti-pilling property of fiber is good.Be mainly used in blending such as wools, viscose glue, acrylic and make cotton type or wool fabrics, can one-bath process during dyeing, reach and stay white, the depth, special effect such as heterochromatic.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of cross ECDP/PET composite flame-proof fiber is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of cross ECDP/PET composite flame-proof fiber, with fire-retardant master granule, ECDP section and PET section mix earlier, carry out spinning by the technology of melt spinning, and long filament is carried out the fiber that required specification was processed and be cut into to boundling, drawing-off, two dimension or three dimensional coil crimp; Used spinnerets is the cross spinnerets;
Described fibre section is shaped as cross;
Long (a) wide (b) of described fiber is than being 5: 3;
Described fiber Denier was 0.5～5 dawn.
Described fire-retardant master granule is a polyster fibre level fire-retardant master granule model: FR-405A color outward appearance: white plates particle; Flame retardant agent content: 85%; Fusing point: 140 ℃; Decomposition temperature: 310 ℃; Products characteristics: possess good dispersiveness, available from Shijiazhuang Jin Di Chemical Industry Science Co., Ltd.
Compared with prior art, good effect of the present utility model is:
(1) technological process of the present utility model is simple, can produce at existing equipment, increases the benefit;
(2) product purpose of the present utility model is extensive.
