Description
Technical field
The utility model relates to textile technology field, and particularly a kind of mechanical compact spinning manufactures the aramid fiber cladded yarn of the method for aramid fiber yarn and cladded yarn thereof, device and preparation.
Background technology
Aromatic polyamide fibre is the synthetic fiber obtained through polycondensation, spinning for raw material with aromatic diamine and acyl chlorides, is called for short aramid fiber.Principal item has PPTA (abbreviation p-aramid fiber) and poly(isophthaloyl metaphenylene diamine) (abbreviation meta-aramid), p-aramid fiber is applied mainly as high-strength high-modulus fibre, and meta-aramid is mainly used as refractory fibrous material, aramid fiber is one of special fibre that in global range, total quantity consumed is maximum.
Aramid yarn and cladded yarn thereof are its a kind of important application modes.But aramid fiber is in the process of spinning, because the cohesive force between fiber and fiber is poor and add and easily produce electrostatic buildup man-hour, cause combing difficulty higher, easily twine easily stifled etc. problem, cause fiber yarn forming filoplume more, more obvious on the impact of aramid fiber cladded yarn especially, often make the processing of later process comparatively difficulty and the presentation quality of goods is not high.
The people such as Luo Shuhua propose to adopt the compact spinning apparatus of traditional negative pressure induced-draft to attempt spinning meta-aramid in " development of aramid fiber 1313 compact spinning " literary composition, achieve good effect, the Yarn filoplume of spinning obviously reduces, thus can improve the class of inflaming retarding fabric.
So-called compact spinning spins also known as gathering, is on spun yarn equipment, separately adds a tight concentration zones after drafting system, making fibre bundle when twisting resultant yarn, eliminating resultant yarn trigonum.Consequently harmful filoplume of yarn greatly reduces, and the brute force of yarn is improved, make subsequent technique easily, cost reduces, production efficiency improves, fabric appearance investigation.
But propose in " development of aramid fiber 1313 compact spinning " literary composition to adopt the compact spinning apparatus of traditional negative pressure induced-draft to there is some problem following: the complex structure of (1) negative pressure induced-draft compact spinning, take up space comparatively large, synchronous assembling cored device smooth operation very difficult; (2) congregational rate of Yarn filoplume is obvious by the impact of negative pressure value size, and the negative pressure value size between each ingot need ensure unanimously, needs special messenger to be responsible for testing to reduce ingot difference to each ingot; (3) operation cost is high, because of this technique need subnormal ambient under operate, cause energy consumption to increase; (4) the grid apron of this compact spinning apparatus or the minute aperture of mesh drum easily block in process of production.
Utility model content
The purpose of this utility model is for the weak point existing for above-mentioned aramid yarn and cladded yarn preparation method thereof and provides a kind of mechanical compact spinning to manufacture the device of high-quality aramid fiber cladded yarn.Which solves the problem that cladded yarn core easily exposes, simplify aramid fiber cladded yarn aft-loaded airfoil operation, obviously improve the outward appearance of the woven and knit fabric of aramid fiber, there is feature that is simple, efficient and cost-effective.The aramid fiber cladded yarn produced can be widely used in cut resistant, the multiple protection field such as fire-retardant, high temperature resistant.
To achieve these goals, the technical scheme that adopts of the utility model is as follows:
The device of the aramid fiber cladded yarn that machinery compact spinning manufactures, comprise cladded yarn core godet roller, accurate guide wheel, front roller, front leather roller, draw yarn roller, a yarn feeding jaw is formed between described front roller and described front leather roller, described front roller and described drawing form one between yarn roller and draw yarn jaw, it is characterized in that, also comprise a mechanical compact spinning apparatus, described mechanical compact spinning apparatus is arranged on front leather roller, draw yarn roller, between front roller three, described mechanical compact spinning apparatus and front leather roller, draw yarn roller, close contact between front roller, make front leather roller, draw between yarn roller and form a complete totally enclosed negative pressure chamber, the center of aramid fiber rove bar aimed at exactly by the cladded yarn core brought by heart yarn core godet roller and accurate guide wheel, cladded yarn core and aramid fiber rove bar converge rear common fed by the yarn feeding jaw between front leather roller and front roller and with front roller synchronizing moving, by the fiber channel in mechanical compact spinning apparatus, be transported to safely and drawn yarn jaw.
In a preferred embodiment of the present utility model, described mechanical compact spinning apparatus is one without the need to the magnetic mechanical compact spinning apparatus of independent power.
Owing to have employed technical scheme as above, device of the present utility model does not need to carry out too much change to main frame, only front leather roller is taken off and change mechanical compact spinning apparatus, take up space less, this mechanical compact spinning apparatus structure is accurate, core displacement in yarn resultant yarn process is reduced, thus is conducive to spinning high-quality aramid fiber compact spinning cladded yarn, and between ingot between yarn, difference is less; Lower to environmental requirement.
Accompanying drawing explanation
