Abstract
Controlling the crystallization difference of polymer produces optimal polymer separation state so that the composite fibre can open during dyeing and finishing naturally rather than chemically or physically. The present invention can raise prodn efficiency and fibre strength.
Description
The present invention relates to a kind of composite fibre and open fine method for making naturally, its mainly be add nucleator in a kind of therein condensate add mould release or add catalyst control its in conjunction with the time viscosity differences or improve the precursor coiling speed, thereby control polymeric crystallization difference, provide the release state of condensate the best, to improve its economic benefit.
Manufacturer must be opened fibre when producing composite fibre now, makes composite fibre have following advantage:
(1) allow the user when wearing, have slightly gas permeability.
(2) have higher water imbibition and reach circulation preferably.
(3) have higher fabric volume and aqueous vapor and air permeability preferably.
(4) has higher covering power.
(5) soft careful feel is arranged, be different from general artificial fibre.
For convenience of description, in this specification tradition or composite fibre of the present invention qualification are made of polyamide-based (Nylon) fiber and two kinds of condensates of polyesters (Polyester) fiber, yet, these explanations just exemplify the present invention and may how to be implemented, so these specific materials should not be understood that restriction of the present invention.
Traditional fiber opening method can be divided into two kinds by summary, a kind ofly opens fibre (claiming machinery to open fibre again) for physics, another kind ofly opens fibre for chemistry, and the examination division is as follows:
(1) physics is opened fibre: see also shown in Figure 3ly, it opens fine flow process for physics, and it just can be finished opening fibre → weave cotton cloth → dyeing and finishing through preparing condensate → spinning → false twisting.
Prepare condensate: as shown in Figure 4, condensate A10 (polyamide) and condensate B20 (polyester) are inserted respectively in each extruder 30, and heating for dissolving extrudes in extruder 30, make the control of polyamide (condensate A) 10 and polyester (condensate B) 20 process measuring pumps 31 and enter spinning zone (SPINPACK) 32, then to spin the quite low speed of fast 500-1500m/min, utilize coiling machine 70 to batch it, wherein can be through cooling zone 40, extension area 50, heat set zone 60, and obtain the composite fibre 80 of structure as shown in Figure 5.
Next composite fibre 80 is twisted earlier with 200T/M, again with 180 ℃, over feed rate(OFR) 0,5% condition are carried out false twisting processing, make composite fibre in two kinds of compound compositions, obtain different contractions and uphold effect and have the fluffy fine state of opening, again through weaving cotton cloth, the process of dyeing and finishing, make it to become cloth with color and luster.
Yet this processing mode has following shortcoming:
1. it adopts and opens fine mode of weaving cotton cloth again earlier and finish, and makes precursor become fluffy state before not weaving cotton cloth, and just weaves cotton cloth then, and this processing mode is quite difficult, and fracture of wire easily, except make produce slowly, more increase the burden of cost.
2. the composite fibre after fibre is opened in false twisting, the distribution of its intensity is also inhomogeneous, destroys the intensity of composite fibre easily.
(2) chemistry is opened fibre: see also shown in Figure 6ly, it opens fine flow process for chemistry, through preparing condensate → spinning → weave cotton cloth → decrement processing → washing → dyeing and finishing, can finish.
The process of preparation condensate and spinning is the same with the mode that physics is opened fibre, but made composite fibre 80 is directly used in and weaves cotton cloth after the process spinning, impose the process of decrement processing after weaving cotton cloth, can adopt the mode of adding caustic soda (NaOH) to finish, make condensate B20 (polyester) the composition dissolving of composite fibre, only remaining cross section is the polyamide monofilament of division shape, as shown in Figure 5, thereby reach out the purpose of very thinization, make composite fibre have fluffy state, through the process of washing caustic soda (NaOH) is removed again, carried out dyeing and finishing then, make it to become cloth with color and luster.
Though this processing mode is opened the easier processing of fibre than physics, still has following shortcoming:
1, because the composite fibre adsorption is strong excessively, will cause the residual problem of caustic soda after the decrement, and the following puzzlement of deriving is grown thickly as the flavescence of embryo cloth, colouring problem, oligomerization zoarium (Oligmer) is removed difficulty, cylinder groove pollution etc.
2, for the state of dissimilar (different fiber, section, configuration of surface etc.) combination, the difference of decrement speed produces, and will cause side decrement extremely, and makes the strength reduction of fiber.
3, composite fibre is very responsive for the unusual fluctuation of reduction rate, 1% decrement rate variance, and the difference of feel is just very big, generally speaking, must not surpass 13%.
4, chemistry is opened fibre except needing be considered carefully for the wastewater treatment environmental issue after storage-stable, operational security, processing stable homogeneous, cooling property, draining and the washing of medicament, and has increased cost relatively.
The inventor is because conventional physical is opened fibre or chemistry is opened fine shortcoming, invent out a kind ofly reduce cost, enhance productivity, precursor has intensity, sense of touch is good, do not have environmental issue when making open fine method for making naturally.
Main purpose of the present invention is: provide a kind of composite fibre to open fine method for making naturally, its mainly be add nucleator, mould release or catalyst in a kind of therein condensate or control its in conjunction with the time viscosity differences or improve the coiling speed of composite fibre, thereby control polymeric crystallization difference in advance, the release state of condensate the best is provided, make the present invention open fibre without physics or chemical mode, just can be when dyeing and finishing, naturally open fibre smoothly, reach and meet economy, free of contamination problem.
