Nylon micro-textured yarn production equipment and production process

Abstract

The invention provides a nylon fine textured yarn producing device and a producing process. The producing device comprises yarn leading supports, a yarn cutting device, a twister roller, a twister, a deformation hot box, a false twister, a cooling plate, an output roller, an oil supplying wheel, a yarn breaking detector and a forming roller which are connected sequentially. The yarn leading supports are in three rows and the angle between two adjacent rows of yarn leading supports is not more than 45 degrees. The false twister is a porcelain-ammonia combined false twister. The producing process is that pre-oriented yarns of nylon 6 (or nylon 66) pass through the yarn cutting device through the three rows of yarn leading supports respectively to directly enter into the twister roller, then are led to the twister and guided into the deformation hot box, enter the porcelain - ammonia combined false twister after being led out, contact with the cooling plate and enter into the output roller, then the yarns pass the oil supplying wheel after coming out from the output roller and then enter the forming roller through the yarn breaking detector to be manufactured into nylon microfine draw textured yarns. Broken filaments are reduced, fiber strength are enhanced, evenness is improved and dyeing aberration is lowered by using the micro-tension compact yarn leading supports and the porcelain-ammonia combined false twister.

Description

technical field [0001] The invention relates to the technical field of synthetic fiber textured yarn production, in particular to a nylon fine textured yarn production device and a production process that reduce broken strands, increase fiber strength and improve dyeing performance. Background technique [0002] Nylon micro-stretched yarn refers to nylon stretched yarn with a denier perfilament (English abbreviation "dpf") of less than 1.0. It is widely used in intimate underwear fabrics, tights fabrics, high-end thermal sweat-absorbing socks and various clothing fabrics that require softness, moisture absorption and sweat-wicking effects due to its soft hand feeling, good moisture absorption performance, and good sweat-wicking effect. [0003] However, it is precisely the characteristics of fine nylon textured silk fibers that single filaments are fine and easily damaged, which makes it difficult to realize the traditional texturing process on existing chemical fiber textur...

Problems solved by technology

In this process, the wire guide frame is at an angle of 90°, the thread sliver introduction tension is relatively large, the phenomenon of stretched yarn broken strands is serious, and the fiber strength is not enough. In addition, the false twister adopts a full ceramic disc or a full polyurethane disc, Poor deformation effect, damage to filaments, resulting in uneven dyeing of filaments
