Abstract
The utility model relates to a fire resistant cross-shaped PET fiber prepared from fire resistant master batch and PET slices by melt spinning of a cross-shaped spinneret plate, wherein the fiber is cross-shaped; the ratio to the length (a) to the width (b) of the fiber is 2: 1; and the denier of the fiber is 0.5-4 D. The fire resistant cross-shaped PET fiber has the following advantages that: the technological process is simple and the fiber can be produced with the existing device, thereby improving the yield and having wide use of product purpose.
Description
[technical field]
The utility model relates to the functional fibre technical field, specifically, is a kind of fire-retardant cross PET 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.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of fire-retardant cross PET fiber is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of fire-retardant cross PET fiber is made through cross spinnerets melt-spun by fire-retardant master granule and PET section, it is characterized in that described fibre section is a cross;
Long (a) wide (b) of described fiber is than being 2: 1;
The dawn number of described fiber was 0.5～4 dawn;
Described fire-retardant master granule is a polyster fibre level fire-retardant master granule shape number: 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 invention 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.
[description of drawings]
Fig. 1 fibre section of the present invention schematic diagram.
