Abstract

The invention provides a nylon yarn-dyed weaving raw yarn warping method. The method is characterized by comprising the following steps that 1) nylon raw yarn is spun into compact warp yarn, wherein the raw yarn and the compact warp yarn have the same vertical center line, and the distance between the raw yarn and the compact warp yarn is 92-104 cm; 2) warping production is conducted, wherein thedensity of the compact warp yarn is 400-450 g / dm<3>, a creel and the hung warp yarn are parallel, the hands are brushed with talcum powder for loom threading, and the humidity of the yarn during loomthreading is 63-70%; 3) reed swinging, wherein every 9 pieces of yarn serve as a row and swing into reed dents in order, and each reed dent needle is 2 mm distant from the last one and is sequentiallylengthened; 4) two static elimination devices are additionally installed on a warping machine and started during warping; 5) the density of warp beams is 300-500 g / dm<3>, the warping speed is 300-600m / min, and the inner and outer tightness of a warping shaft is consistent; 6) the seam heading range is 400-790, the swing amplitude of the reed dents is 2-4.5 mm, the pressure of a yarn pressing roller is 0.15-0.20 N, and the tension of the yarn at a rear creel is 2-4 cN. The method has the advantages of being convenient, quick, high in yield, low in consumption and suitable for meeting the requirements of the current market for short delivery time and fast pace.

Description

technical field [0001] The invention provides a method for warping raw nylon yarn-dyed yarns, which belongs to the technical field of textile printing and dyeing. Background technique [0002] The output of yarn-dyed fabrics in my country is increasing year by year. Because yarn-dyed fabrics are dyed first and then woven, the colors do not match each other, the lines are clear, and they can also be made into styles with great contrast between warp color and weft color. Look at the color from different angles Different, deeply loved by consumers. [0003] The current production of nylon fabrics is mostly used for weft yarns. The production of warp yarn dyeing can only use the warping method of colored yarns. The warping of colored yarns has the disadvantages of low production efficiency and large production waste. Color difference and other quality problems. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the traditiona...
