Method for weaving pure China hemp high-count weak strength yarn home textile fabric

Abstract

The invention discloses a method for weaving a pure China hemp high-count weak strength yarn home textile fabric, which comprises the following steps of: performing micro tension control on China hemp high-count weak strength yarns on a warping machine, wherein the open length of a warp beam is 2,400 millimeters, the tension of a tension rod is 4 to 10 grams, the number of the total warps is 18,338 to 23,520, the number of single shaft heads is 750 to 1,040, the number of parallel cylinders is 20 to 28 and the volume of filling cylinders is 750 to 1,040; performing sizing, wherein the tension is 4,000 to 4,100N, the sizing mode is single immersion and single pressing, the size force is 18 to 24KN, the wet elongation is 0.1 to 0.2 percent, sheet yarns are prevented from being twisted, the backing-off tension of the warp beam is 650 to 750N, the volume of a size tank is 320 liters and the size immersion length is 60 to 80 centimeters; performing up and down alternated lease by adopting a STAUBLI OPAL-3600 automatic lease machine made in Switzerland, and performing drafting by adopting a STAUBLI DELTA 110-3600 automatic drafting machine made in Switzerland; and performing low-tension weaving by using a broad-breadth single weaving shaft loom, wherein the feeding tension is 3,000 to 4,000N, the speed is 450n / min, the height of a rear beam is less than 4 centimeters, the temperature of a weaving workshop is 25 to 30 DEG C, and the relative humidity is 68 to 72 percent. According to the method, the efficiency of a fabric machine is improved, the discharge quality is ensured, the yarns are well enhanced, the weaving broken ends of the fabric machine are reduced, and the fabric quality is good.

Description

technical field [0001] The invention relates to a weaving method for home textile fabrics, in particular to a weaving method for home textile fabrics made of high-count pure hemp weak-strength yarn. Background technique [0002] The traditional weaving process route of high-count and high-density home textile fabrics is: the first step ----- warping (low tension); the second step ----- sizing (two high and one low: high pressure, high density, low viscosity); the third step ----- manual drawing; the fourth step ----- weaving (early shedding, late beating, middle back beam, middle tension). The characteristics of pure hemp viscose high-count yarn are: high fibril denier and low strength, low yarn strength, large wet elongation, low wet strength, large twist, easy twisting of yarn pieces, and difficult sizing production. The cloth machine has a lot of broken times, many broken defects, and the cloth surface is not smooth. Pure hemp viscose high-count weak-strength yarn is use...
