Description
Technical field
The present invention relates to clothes material technology field, and in particular to a kind of preparation technology of acrylic fiber.
Background technology
Acrylic fiber（Polyacrylonitrile fibre）Have the title of artificial wool, have it is soft, bulk, easy dye, it is bright in colour, resistance to
Light, antibacterial, the advantages that damaging by worms is not afraid of it.Elasticity is good, and rebound degree can still keep 65% during elongation 20%, fluffy curling and it is soft, it is warming
Property is higher than wool by 15%, and intensity is higher than wool 1-2.5 times.Sun-proof function admirable, open-air exposure 1 year, intensity only declines 20%.It is fine
190-230 DEG C of softening temperature, the acidproof, antioxidant of energy and common organic solvents are tieed up, but alkali resistance is poor.According to different purposes
It is required that pure can spin or with natural fibre blended, its textile is widely used in fields such as clothes, decorations.
In addition, high-shrinkage fibre has potential highly shrinkable by oneself with it a variety of knit can be made with conventional fibre blending
Thing, have the characteristics that soft, fabric is abundant, plentiful, warmth retention property is good, can also produce unusual luster effect.Therefore, it is high to receive
The market demand of contracting acrylic fibers product is increasingly good.
The phenomenon of fuzz balls can all occur in use in most of synthetic fibers.Although acrylic fibers have U.S. of artificial wool
Reputation, because acrylic fiber macromolecular is in irregular helical conformation, without real crystalline texture, the strength of fiber is than natural
Fiber and regenerated fiber are much higher, and the synthesis speed of its product surface fiber spherolite is more than exfoliation rates, thus frictional force without
In the case that method eliminates fiber spherolite, the fiber spherolite president's phase formed retains on the surface of the fabric, is knitted so as to have a strong impact on
The outward appearance and snugness of fit of thing.At present, the method for reducing acrylic fibers balling-up mainly has：(1) in fiber or fabric face coating one
Layer modification agent, to reduce fabric face pilling.This method subject matter is that finishing agent once fails in fiber surface,
The anti-pilling property of fiber just declines；(2) change in spinning production process by acrylic fiber and reduce pilling, lead to
The fuzz balls performance for crossing control acrylic fiber spinning production process technology condition to change and reduce fiber, but it is ineffective, and
And the dyeability of fiber is poor, it is impossible to meets the requirement of production high-grade fabric, anti-pilling property grade only reaches 3-4 levels.
The content of the invention
The purpose of the present invention is to be directed to problem of the prior art, there is provided a kind of high convergency and the acrylic fiber of anti pilling and its

（5）It is 1.4-1.8 in stretch rate by the tow after sizing by steam chest：Tow is stretched under conditions of 1,
The acrylic fiber is made.
Further, the step（1）In, required raw material includes 92 parts of acrylonitrile, 8 parts of vinyl chloride, 5 parts of vinyl acetate and
0.4 part of methylpropene sodium sulfonate.
Further, the step（2）, it is necessary to which filament surface after drawing coats smooth agent after completion.
Further, the smooth agent is the compound of nonionic surfactant and cationic surfactant, described
Nonionic surfactant, cationic surfactant, the mol ratio of smooth agent are 2：4：1.
Further, the addition of the smooth agent accounts for the 0.3-0.7% of tow gross mass.
Further, the thermal finalization handles 45-50min under 300-400kPa.
Further, the step（1）The rectangular opening length-width ratio of middle spinneret is 2-13:1, the hole count of spinneret is
10000-40000。
Further, the step（1）The middle temperature into stoste during coagulating bath is 80-90 DEG C, coagulation bath temperature 30-
45℃。
The present invention compared with prior art, has following beneficial effect：
The present invention mixes acrylonitrile, vinyl chloride, vinyl acetate and methylpropene sodium sulfonate according to specific proportioning, poly- through suspending
The steps such as conjunction obtain co-polymer, drop low-fiber glass transition temperature, remaining routinely spinning technique spinning, enhance fiber
Flexibility and thermoelasticity, the shrinkage of fiber is improved, make acrylic fiber be easier to paint, while obtain acrylic fiber anti-pilling property
4 grades of grade ＞, its hook are by force 0.6 ± 0.2CN/dtex.
Concentration, temperature of the invention by adjusting stoste, concentration, temperature, the internal circulating load of solidification liquid, Reasonable adjustment washing temperature
Degree, drafting multiple, and drying, the temperature of sizing, pressure, and the technological parameter such as draw ratio of high convergency are controlled, make the present invention
