Problems solved by technology

There are still many technical difficulties in the research and development of domestic flat-section nylon fibers. The greater the flatness in R&D and production, the more difficult it is to process the spinneret, and the more difficult it is to spin and post-process.

Abstract

The invention relates to an imitation rabbit hair chinlon 6 fiber and a production method of the imitation rabbit hair chinlon 6 fiber. Fiber-stage chinlon 6 with the relative viscosity being 2.47+/-0.02 and the moisture content being less than or equal to 500ppm are sliced and are put into a material cabin; the materials are heated to a fusion state by a screw extruder, and are fed into a spinning manifold through a flux distribution pipeline; the flux enters a spinning assembly in the spinning manifold, and is sprayed out through flat cross section spinning orifices; the spinning orifices are arranged in a mode of a linear shape; lateral blowing is adopted for cooling a flat cross section nascent fiber; the flux streamlet is solidified into a fiber in high-speed movement; the cooled fiber beams are oiled and then enter a spinning passage; the silk beams complete the winding forming on a winding head by a spinning-stretching one-step method after passing through a cold roller, a hot roller, a net device and a tensioning roller. The imitation rabbit hair chinlon 6 fiber has the advantages that the flatness degree is 6.0 to 10.0, the thread density is 1.5 to 9D; a product has the characteristics of softness and fineness; the handfeel and the luster are like those of the rabbit hair; meanwhile, the excellent fluffiness, dirt resistance and anti-pilling performance are realized.

Description

【Technical field】 [0001] The invention belongs to the technical field of synthetic fibers, and specifically refers to a rabbit-hair imitation nylon 6 fiber and a production method thereof. 【Background technique】 [0002] The total output of China's chemical fiber exceeds 40 million tons, ranking first in the world for 16 consecutive years. The proportion of polyester production capacity and demand in the total domestic synthetic fiber remains at 88%, and the proportion of nylon production capacity and demand in the total domestic synthetic fiber increases to 6%. On the whole, there is a relationship of oversupply of domestic synthetic fibers. Due to overcapacity, the profit margin of polyester, nylon and other general fiber industry chains will be compressed, and the operating rate will drop. International high-value and functional fiber research is active, and the product profits are high. For example, well-known international companies include South Korea's High-performan...
