Abstract
The invention relates to a polyester filament, particularly to a low-melting-point polyester filament in skin-core structures. The low-melting-point polyester filament in the skin-core structures is mainly applied to fields such as nonwoven fabric such as carpets, decoration, glue-free cotton and hot pressing modeling and good in machinability, enables machining conditions to be easy to control and is low in energy consumption and good in spinning performance. The low-melting-point polyester filament in the skin-core structures is mainly formed by two layers of structures which comprise the skin layer and the core layer; the cross section of the low-melting-point polyester filament fiber is in round shapes and the like. The low-melting-point polyester filament in the skin-core structures solves the problems that preparation of the low-melting-point polyester fiber in the skin-core structures by composite spinning in the current is high in energy consumption and the condition stability is poor during the machining process.
Description
Technical field
The present invention relates to a kind of polyester filament, especially a kind of nonwoven fabric that is mainly used in is as carpet, ornament, without the polyester filament of a kind of low melting point skin-core structure in collodion, the field such as hot-forming.
Background technology
Low melting point core-skin composite fiber is mainly used in heat bondable fibre, and in non-weaving cloth is produced, main effect is that low-melting fiber cortex polymer melts at a certain temperature, thereby in fiber web, plays the effect of cohering; Low-melting point polyester core-skin composite fiber is a kind of meldable fibre, the copolyester with low melting point thing that general its cortex fusing point is 95～150 ℃, sandwich layer composition is the polymer of other compositions, be mainly used in nonwoven fabric as carpet, ornament, without collodion, the field such as hot-forming, there is good machinability and low energy consumption effect.
For low melting point skin-core structure composite polyester fiber, the composition of its cortex and sandwich layer and ratio have more report at present; As patent of invention name is called major diameter sheath-core type hot molten monofilament and uses thereof, its fibrocortex adopts polymer P ET/PA6 or PE, and sandwich layer adopts polymer P ET, PA6, PA66 or PP.Filament diameter is 0.08～5mm, and filament strength is 2.5～7.0cN/dtex, and it is 5～95% that cortex accounts for monofilament gross weight, and sandwich layer is surplus; Patent of invention name is called method for preparing sheath core composite long fiber with low melting point,, its cortex adopts copolyester with low melting point, and it is a kind of in conventional PTT, PBT, the PA6 of 220～230 ℃ that sandwich layer adopts fusing point, and cortex is 20:80～80:20 with the compound ratio of sandwich layer; Patent of invention name is called a kind of heat that adopts and binds the method that core-sheath compound fibre is prepared leather fabric, and its cortex adopts low melting point polyester fiber or low melting point nylon fibre, and sandwich layer adopts conventional polyester fiber, and wherein low melting point polyester fiber content is 5%～8%; Patent of invention name is called sheath-core type hot molten monofilament, and its cortex adopts low-melting point polyester, and sandwich layer adopts conventional polyester, and filament diameter is 0.08～2mm, and fiber core diameter is 0.05～1mm; But for low melting point skin-core structure composite polyester fiber, above patent mostly is cortex and utilizes low-melting point polyester copolymer, but the utilization of sandwich layer is mainly to adopt the materials such as conventional PET, PBT, PA6, PA66, PP, because cortex and sandwich layer fusing point differ greatly, make to be easy to produce high energy consumption in existing melt spinning process and the shortcoming such as processing conditions is wayward, and spinning properties is poor.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and have that good machinability, processing conditions are easy to control, the polyester filament of low energy consumption and the good a kind of low melting point skin-core structure of spinning properties.
In order to achieve the above object, the polyester filament of a kind of low melting point skin-core structure that the present invention is designed, it is comprised of cortex and sandwich layer double-layer structure, and the cross section of polyester filament fiber is circular; Described cortex is that low-melting point polyester forms, and its fusing point is 90～120 ℃; Described sandwich layer is polyolefin layer, and it is that random polyethylene, random polyethylene and random polypropylene composition polymer form, and the diameter of sandwich layer is 15～40 μ m, and the fusing point of sandwich layer is 110～140 ℃; The mass ratio of cortex and sandwich layer is 1:9～2:8, and the filament diameter of described polyester filament fiber is 20～60 μ m, and filament strength is 2.3～3.5cN/dtex.
In sandwich layer polyolefine material, the mass fraction of random polypropylene in polyolefin is 1～50%, and polyolefinic fusing point is 110～140 ℃, and the diameter of sandwich layer is 15～40 μ m.
The filament diameter of described polyester filament fiber is preferably 40 μ m.
Described sandwich layer diameter is preferably 30 μ m.
According to the polyester filament of above-described a kind of low melting point skin-core structure, its cortex has compared with the polyester of low melting point and sandwich layer and has compared with the polyolefine material composite spinning of low melting point and obtain, the problems such as current composite spinning is prepared in low melting point skin-core structure polyester fiber process, and the high energy consumption of bringing and processing conditions process stability are poor have been solved; And this product only need carry out heat treated, can form bondingly, be mainly used in nonwoven fabric binding material and polyester fabric low melting point binding material, have broad application prospects.
