Abstract
The invention relates to a low-elasticity network fiber with a cross odd-shaped cross section, which is prepared according to the following steps: using dimethyl terephthalate to perform transesterification with 1, 4-butanediol, and performing polycondensation reaction by using organic titanium or tin compounds and tetrabutyl titanate as catalysts at higher temperature and vacuum degree so as to prepare a PBT polyester slice. The low-elasticity network fiber is characterized in that a spinneret plate with a cross spinneret orifice is used for spinning, the specification of the fiber is between 50 and 75 D/36f, and the used spinning condition is basically same as that of the prior semi-dull PBT polyester. The low-elasticity network fiber maintains the excellent properties of the PBT fiber so that a dyed fabric has excellent glossiness and bright and new degree, and also has excellent elongation elastic recovery rate, softness, easiness for dyeing, good drapability, fluffiness, good handfeel and softness for a fabric, and quick-drying function for the fabric, thus the low-elasticity network fiber is widely applied in various fields.
Description
Technical field
The present invention relates to a kind of PBT polyester filament, specifically is a kind of low stretch network fibre with cross special cross-section, belongs to the polyster fibre technical field.
Background technology
Because natural fabric has many good qualities, cotton fiber and cocoon fiber have own exclusive wearing comfort separately, how to improve the quality and the function of chemical fibre, are the targets that chemical fibre industry is pursued for a long time.The development of polyester industrial makes our life become rich and varied, and the diversity in lining market has been enriched in the exploitation of many new polyester modification kinds greatly.In recent years, along with China's economic development is progressively accelerated,, make the polyester industrial of China that rapid progress arranged with integrating with of world trends.Chemical fibre market is immediately following world trends.
In recent years, the various decorative textile product consumptions of China increase year by year, and only the automobile interior trim fiber consumption reached 80,000 tons in 2005, can reach more than 100,000 tons by 2010.At present, decorative textile product adopts multiple fiber, because pluses and minuses are respectively arranged, twists with the fingers mixed method of knitting so generally adopt two or more fibers to hand over, to improve the combination property of fabric.But the mixed fabric influence is recycled, and easily contaminated environment does not meet the environmental protection principle, for the ease of recycling, trends towards using single fiber in the world.And the PBT fiber has overall merits such as good dyeability, resilience, pollution resistance, recuperability, will in numerous chemical fibres, win, for example on curtain, bed, in the incrustation product markets such as wall to wall, mosquito net, sofa cover, tablecloth, toy, interior automotive trim decorations very big development prospect and good economic benefit be arranged.
The PBT fiber possesses einnehmen function, but is difficult to the dyeing uniformity of controlling fiber, when being used with other fibers, typically exists lining owing to different with other fiber dyeing speeds, causes the difficulty of dyeing aspect.The more important thing is when exploitation lining in summer and clothes, when generally requiring lining to have good hand feeling, bulkiness, drapability, to also have two prior indexs, one of them index is that lining will have gorgeous color and bright and new degree.Another index is the hydroscopic fast-drying function of lining.
Will have gorgeous color and bright and new degree about lining, the big lustrous fibre that generally uses big glossy polyester and spinned has better brightness and colored light freshness.But since the crystallization property of PBT polyester uniqueness, the easier crystallization of macromolecule internal structure, and this has just caused, when spinning, when especially spinning common big lustrous fibre, tow is subjected to the spinning condition influence of fluctuations, the crystallization of fiber is restive, causes the not fair phenomenon of dyeing.This has had a strong impact on the exploitation that spectrum row PBT fiber is arranged greatly.
Summary of the invention
The present invention be directed to present routine has light PBT polyester and fiber thereof greatly in exploitation and use, and existing deficiency is for the dyeing uniformity of raising fiber, give the fiber moisture absorption sweat discharging functions.A kind of low stretch network fibre with cross special cross-section is provided.
The present invention program's method comprises uses dimethyl terephthalate (DMT) and 1, and the 4-butanediol is by ester exchange, and under higher temperature and vacuum, is that catalyst carries out polycondensation reaction with organic titanium or tin compound and butyl titanate, prepares the PBT polyester slice.
The present invention program uses the spinnerets spinning of cross shaped spinneret orifice, fiber dimensious is 50D～75D/36f, the spinning condition of employed spinning condition and conventional half delustring PBT polyester is basic identical, because the good crystallizing power of PBT polyester, in the actual spinning process, do not need pre-crystallization process, and the drying of directly cutting into slices, baking temperature is controlled at 130～135 ℃.Its spinning condition sees Table one,
Table one: spinning screw temperature control
| One district | Two districts | Three districts | Four districts | Five districts | Elbow | Casing |
| 261℃ | 275℃ | 275℃ | 280℃ | 278℃ | 278℃ | 280℃ |
Temperature also will be looked concrete spinning situation adjustment accurately.
The described spinning of this programme at first will spin corresponding POY, and the spinning speed of POY fiber is 2500-3200m/min.The POY product of spinning passes through corresponding stretching texturing craft again, and draw ratio 1.6 prepares the low stretch network product DTY of corresponding specification.The spinning technique of POY described in the scheme, DTY is identical with conventional spinning technique, notes controlling well temperature, humidity and the draft temperature of lateral blowing in the spinning process.
The low stretch network fibre that the present invention is prepared with cross special cross-section.Compared following characteristics with conventional PBT polyester fiber:
1: because spinning material is for there being light PBT polyester slice greatly, and use the low stretch network long filament DTY of cross shaped spinneret orifice spinning specification as 50D～75D/36f, therefore, the low stretch network long filament that is obtained with cross special cross-section, when having the characteristic of big lustrous fibre, also have soft gloss as the real silk, cooperate the good dye-uptake of PBT fiber, have good gloss and bright and new degree after the textile dyeing.
The 2:PBT low stretch network fibre has kept the good characteristic of PBT fiber, has fabulous elasticity of elongation response rate and soft easy dyeing, good drapability, bulkiness, lining pleasant softness is good.
3: owing to use star section, make and formed many capillary slots between the fiber, in lining, formed capillary channel, thereby make lining to absorb moisture rapidly and spread, because the PBT polyester has certain hydrophobic property again, and the cross special-shaped surface area of whole moisture evaporation that makes significantly enlarges, the moisture of diffusion can evaporate rapidly simultaneously, therefore, lining has quick-drying function again.
The specific embodiment
Embodiment 1
With ormal weight PBT polyester slice, be delivered directly to the chip drying tower, baking temperature is controlled at 130 ℃, control 4～5.5 hours drying time, moisture in the test section, reach dry standard after, start spinning equipment, carry out slice spinning, spinning screw is respectively distinguished the temperature control of temperature and elbow and casing and is seen above-mentioned table one.Control lateral blowing temperature is at 20～21 ℃, and humidity is controlled at 65～70%, and air quantity is looked the adjustment of coiling situation.The control winding speed is 2900m/min, and the POY specification that is spinned is 83.3dtex/36f, and POY spinning technique and process are stable normal, and through after 24 hours balances, drawn notices that draft temperature is controlled at below 165 ℃.Obtain the cross special-shaped PBT low elastic interlaced yarn DTY that light is arranged greatly of 50D/36f.Fiber quality is good.
