Problems solved by technology

However, the "quantity" of the industry has grown significantly. There are many bulk and conventional products, and the research and development level of high-tech products such as modified fibers, high-fidelity fibers, special functional fibers, ultra-fine denier fibers, high-elastic fibers, and functional fibers is low.

Embodiment 1

[0034] like Figure 1-2 As shown, this embodiment provides a production method for 24-head high-elastic composite pre-oriented fibers, which includes PET and PBT raw materials, and the PET and PBT raw materials are respectively transported, pre-crystallized, dried, melt-extruded and then formed into a spinning melt. The body enters the spinning assembly through the box metering pump; the PET spinning melt and the PTT spinning melt are melted together in the spinning assembly, and the collected melt is spun through dislocation ring blowing, oiling, Network, lower guide plate, upper guide plate, winding forming, inspection, grading packaging, finished products.

[0035] It also includes 24 high-elastic composite pre-oriented fibers. The 24 high-elastic composite pre-oriented fibers are developed using a spinning, drafting and winding integrated machine. The spinning, drafting and winding integrated machine adopts PBT chips and low-viscosity PET chips. In drying, the crystalliza...

Embodiment 2

[0041] A production equipment for a 24-head high-elastic composite pre-oriented fiber applied in claim 1, which comprises a spinning box 1, a heating box 15 arranged on the spinning box 1 for stirring the heating fiber, and a heating box 15 arranged on the heating box 1. The stirring component in the box 15, the conveying component arranged between the heating box 15 and the spinning box 1 for conveying the fibers into the spinning box 1, the filter component arranged in the spinning box 1 for filtering the fibers, and the In the spinning box 1, a scraper assembly located on the lower side of the filter assembly for scraping the fibers in the inner side wall of the spinning box 1, and a silk orifice plate 38 arranged in the spinning box 1 and fixedly connected to the bottom of the scraper assembly, are arranged symmetrically on the left and right sides. Two spinning tensioning assemblies at the inner bottom of the spinning box 1, and heat dissipation components arranged in the ...

Embodiment 3

[0046] A production method of a 24-head high-elastic composite pre-oriented fiber production equipment, comprising the following specific steps:

[0047] S1, prepare fibers: add fibers to the heating box 15, and start the heating box 15 at the same time;

[0048] S2. Mixing fibers: after heating the fibers for a period of time, by starting the stirring motor 2, the stirring motor 2 drives the drive shaft 3 to rotate, the drive shaft 3 drives the bevel gear 1 to rotate, the bevel gear 15 drives the bevel gear 26 to drive, the bevel gear Gear two 6 drives shaft one 8 to rotate, shaft one 8 drives bevel gear four 10 to rotate, bevel gear four 10 drives two bevel gears five 11 to rotate, bevel gear five 11 drives shaft two 13 to rotate, and shaft two 13 drives stirring rod 14 to rotate At the same time, the bevel gear one 5 drives the bevel gear three 7 to rotate, the bevel gear three 7 drives the rotating sleeve 9 to rotate, the rotating sleeve 9 drives the stirring rod 14 to rot...

Abstract

The invention discloses a production method and equipment of 24-head high-elastic composite pre-oriented fibers. The 24-head high-elastic composite pre-oriented fibers comprise PET and PBT raw materials. The PET and PBT raw materials are subjected to conveying, pre-crystallization, drying and melt extrusion to form spinning melts, and the spinning melts enter a spinning assembly through a box metering pump; the PET spinning melt and the PTT spinning melt are collected in a spinning assembly, and the collected melt is spun and then subjected to staggered circular blowing, oiling, pre-networking, lower guide disc treatment, upper guide disc treatment, winding forming, inspection, grading packaging and finished product obtaining.

Description

technical field [0001] The invention relates to the technical field of sheep soft leather, in particular to a production method and equipment for a 24-head high-elastic composite pre-oriented fiber. Background technique [0002] With the continuous progress of society, people's demand for a better material life is increasing day by day, and the requirements for clothing are no longer just staying warm and beautiful, but also require comfort and health. Clothing fabrics spun from ordinary fibers can no longer meet the needs of consumers. However, the industry's "quantitative" growth is obvious, with more bulk and conventional products, and the research and development level of high-tech products such as modified fibers, high-simulation fibers, special functional fibers, ultra-fine denier fibers, high-elastic fibers, and functional fibers is relatively low. In recent years, my country's chemical fiber industry has intensified innovation, paid attention to the overall technolo...
