Abstract
The invention provides a manufacturing method for a three-dimensional crimped bicomponent composite hollow aromatic polyester staple fiber. The manufacturing method comprises the following steps: (1) EVA adsorbs volatile oily essence and swells; (2) with a skin layer as PET, and with a core layer as high polymer formed by blending PE and EVA adsorbing the essence, silks with skin-core structures are sprayed by virtue of a spinneret plate through a skin-core composite spinning component, and then the silks are asymmetrically cooled and formed; and (3) the silks spun in the step (2) are highly stretched, and are dried by hot air after cut off. The aromatic polyester staple fiber manufactured by the invention can be equivalent to a common-strength and common-stretchability cotton-type polyester staple fiber in physical and mechanical properties, can be used for spinning to form textiles with fragrance and also can be used for household textiles, toys, packing materials, decorative materials and the like. Due to the hollow core layer, the fragrance can be continuously and slowly released from the two ends of the aromatic polyester staple fiber, and the adding amount of spice can be reduced to be 1/3-1/10 of that in the prior art. The total cost of the aromatic fiber is greatly reduced.
Description
Technical field
The present invention relates to a kind of manufacture method of three-dimensional crimp bi-component composite hollow aromatic polyester staple fibre, belong to synthetic fiber technical field.
Background technology
Last century the mid-80, polyester fiber industrialization obtains fast development, meanwhile, also obtains extensive investigation and application to the chemistry of fiber and physical modification technology.Wherein, functional textile and fiber obtain effect in the added value of raising weaving final products with improving in the extension of human body einnehmen function and sensory comfort (nice and cool, warming, the color of vision, the fragrance etc. of sense of smell of body sense).Fragrant fiber belongs to a class of functional fiber, and last century, the mid-80 formed achievement in research and mass production in companies such as Japan.
Different fragrance is known from experience people and is produced different feeling and have physiotherapy, expelling parasite, the feature such as antibacterial concurrently, such as, natural cupressin (Cupressin) is to auxiliary sleep quality and expel acarid effective, eucalyptol (Cineole) infects human respiratory tract and has mitigation, also have sterilization and antibacterial effect concurrently, Jasmine essential oil (Jasmine essential) has function etc. that is excited and warm mood to human body.
Fragrant fiber should have two important features concurrently, one be there is volatile oiliness essence can be more stable and be carried in securely on fiber, after fiber process process (such as combing, heating, washing), still can maintain the fragrance that can experience; Two is the physical and mechanical properties and the serviceability that not exclusively affect fiber itself.Melt spinning is the shaping relatively simple method of chemical fibre, and therefore, fragrant fiber has carried out effective trial and defined many patents on the fundamental technology of melt spinning.
Patent CN101294315 discloses a kind of far infrared flat fibre with fragranced, adds far-infrared powder spinning together with the nanometer odor type microcapsules of 2 ~ 6% of 3.5 ~ 12% particle diameter less than 1 micron, obtain the fiber having far infrared and fragrance concurrently in polyester fondant.Patent CN1594684 discloses blending method and produces fragrant fiber method, adopts polypropylene fragrant masterbatch and polyester to carry out co-blended spinning and obtains fragrant fiber.Patent CN1032874 discloses perfume synthetic fibre and manufacture method thereof, adopts microcapsules technology to be loaded in fiber by fragrance.
Adopt the relative technics comparing of said method simple, low cost of manufacture, but fiber keeps the effect of fragrance undesirable, fiber is through washing and textile process, and loss of aroma is obvious, higher to fiber instructions for use, such as, can not use chemical washing liquid etc.; Patent CN 102586943A discloses a kind of sheath-core type aromatic filament of long-acting slow-release, by core-sheath mode, aromatic substance is constrained in sandwich layer to reach the object of slowly-releasing, fiber is made to keep fragrance for a long time, but the fiber of this structure needs fiber high temperature curling in Final finishing step, the physical and mechanical properties of infringement fiber, causes the spinnability of fiber to be obviously deteriorated.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, there is provided a kind of and avoid the curling infringement to fibrous physics mechanical performance of fragrant fiber high-temperature machinery, essence addition is low, lasting fragrance, the manufacture method of wash fast three-dimensional crimp bi-component composite hollow aromatic polyester staple fibre.
The technical solution used in the present invention is: a kind of manufacture method of three-dimensional crimp bi-component composite hollow aromatic polyester staple fibre, and its step comprises:
(1), EVA room temperature or lower than the closed container of 150 DEG C in absorption there is volatile oiliness essence and swelling;
(2), using PET as cortex, spinning temperature 285 ~ 290 DEG C, the method that the EVA of imbibition essence adds as master batch is entered composite spinning casing by twin-screw is blended together with PE, become the sandwich layer of aromatic polyester staple fibre, spinning temperature 190 ~ 220 DEG C, employing spinnerets micropore is the hollow spinneret plate of C type structure, and the winding speed of spinning is 960 ~ 1100m/min, cooling air temperature is 16 ~ 18 DEG C, and wind speed is 4.5 ~ 6m/s;
(3) silk, by previous step spun stretches 4.5 times, and water-bath draft temperature is 60 ~ 70 DEG C, cuts off after oiling, and after cutting off, fiber enters drying equipment, and hot blast temperature is 100 ~ 110 DEG C, makes its sandwich layer hollow and hollow space communicates with ambient atmosphere.
As the preferred technical scheme of the present invention, the raw material weight ratio of sandwich layer and cortex is 10:90 ~ 25:75.
As the preferred technical scheme of the present invention, in described sandwich layer, the part by weight of EVA and PE is 1:1 ~ 1:5.
As the preferred technical scheme of the present invention, described essence addition is 0.01 ~ 0.3% of total weight of fiber.
Manufacture method of the present invention is without the need to machine crimp, self-assembling formation profile can have spiral helicine aromatic polyester staple fibre, and possess the good elasticity of compression and spinning performance, the aromatic polyester staple fibre physical and mechanical properties made is equal to generally generally by force stretches cotton polyester staple fiber, can be used for spinning and make the dulcet textiles of tool, 130 DEG C of disperse dyeing processing can be stood, also Nonwoven Processing Methods can be adopted to make stuffing, for household textiles, toy, packing material, decorative fabric etc.Sandwich layer hollow can make fragrance continue slow releasing from the two ends of aromatic polyester staple fibre, aromatic polyester staple fibre is when repeated multiple times washing, placing half a year more than under natural conditions still can the existence of perception fragrance, compared with technology in the past, the addition of spices can be reduced to 1/3 ~ 1/10 of original technology.The overall cost of fragrant fiber significantly reduces.The raw material weight ratio of sandwich layer and cortex is 10:90 ~ 25:75, can ensure that fiber possesses spinning or non-weaving cloth processing request.
