Problems solved by technology

However, the fibers of hemp must be obtained through processes such as seed removal, retting, and beating, and the growth cycle is long and affected by the environment. In addition, processing conditions and equipment limitations make pure flax and ramie high-count yarn fabrics expensive. Due to the special requirements of hemp on the growth environment, its production is restricted by great geographical factors.

Abstract

The invention relates to a spinning device and a filament yarn processing method with a hemp-like effect, comprising a front drawing area and a rear drawing area, the front drawing area includes a front roller and an electric heating roller, and the rear drawing area includes The middle roller and the back roller are provided with aprons respectively, and a pressure roller is arranged between the middle roller and the back roller, wherein the aprons of the pressure roller and the middle roller are respectively wrapped with emery leather, and the pressure roller and the yarn form a The wrapping angle of the machine is 45-90 degrees, the wrapping angle formed by the upper pressure roller and the yarn is 0-45 degrees, and several metal springs are embedded on the electric heating roller. The method is as follows: feed colored polyester filaments to the entrance of the spinning device, and the filament bundles pass through the rear roller, pressure roller, middle roller, electric heating roller and front roller in sequence. The invention improves the ring spinning technology, spins the polyester filament yarn with the feel of hemp yarn, and at the same time has the feel of hemp and the durability and mechanical strength of chemical fiber, and shortens the production process and cycle.

Description

technical field [0001] The invention belongs to the technical field of processing filament hemp-like fabrics, in particular to a spinning device and a filament yarn processing method with a hemp-like effect. Background technique [0002] The short stripes of different lengths and thicknesses formed on the surface of the linen fabric due to uneven dryness have become the unique rough style of the linen fabric, and also make the fabric cool, breathable, and stiff but not hard. However, the fibers of hemp are obtained through processes such as seed removal, retting, and beating. The growth cycle is long and affected by the environment. In addition, the processing conditions and equipment limitations make pure flax and ramie high-count yarn fabrics expensive. Due to the special requirements of hemp on the growth environment, its production is restricted by great geographical factors. In addition, as a natural fiber, the length and fineness of hemp fiber vary greatly, and there ...
