Embodiment 1

[0026] like figure 2 As shown, the steps of a high-grade flax fabric weaving method based on crystal-modified flax yarn provided by the present invention are:

[0027] The first step, the commercially available woven flax spun yarn is relaxed and wound by 1:3 to form a relaxed cheese yarn;

[0028] The second step, the crystal change modification treatment of the relaxed cheese obtained in the first step, the process is as follows image 3 Shown: put the relaxed cheese into a closed modified kettle, and after vacuuming the modified kettle, first fill with ammonia gas to make the pressure in the modified kettle greater than 3MPa, and then fill with liquid ammonia to immerse all the relaxed cheese And the pressure in the modified kettle is greater than 5Mpa, the liquid ammonia is removed after maintaining the pressure for 3 minutes, and then heating and vacuuming are alternately performed to remove the residual modified medium. The heating temperature is 60 ° C, and the time i...

Abstract

The invention provides a high-grade flax fabric weaving method based on crystallized and modified flax yarns. The method comprises the following steps: in the material preparing stage, woven flax spun yarns are subjected to relaxation and winding, so as to form relaxed yarns on cones; the relaxed yarns on cones are subjected to crystallization and modification treatment; the crystallized and modified relaxed yarns on cones are simultaneously subjected to winding, electronic yarn clearing and waxing, so that weaving yarns on cones are obtained; the weaving yarns on cones are subjected to warping according to the quantity of warp yarns; in the weaving stage, flax grey cloth is woven by taking the weaving yarns on cones as weft yarns, the warp yarns after warping as warp yarns, and drawing weft and warp yarns in an air jet loom; in the dyeing stage, the woven flax grey cloth is subjected to hot dyeing or cold dyeing; in the after finishing stage, the dyed flax grey cloth is rinsed, dried, finalized, preshrunk, wound and packaged to form the high-grade flax fabric. According to the high-grade flax fabric weaving method, the bottleneck of wearability of traditional flax fabric is solved, the flax fabric is enabled to obtain the sense of cotton, the production efficiency is improved, the production cost is reduced, and the energy conservation and emission reduction in the production process are realized.

Description

technical field [0001] The invention relates to a weaving method for high-grade flax fabrics based on crystal-modified flax yarns, belonging to the field of textiles. Background technique [0002] Linen fabric has the advantages of being naturally wide, absorbing moisture and dissipating heat, preventing bacteria and insects, and resisting radiation. It is increasingly valued by people. Weaving methods of traditional linen fabrics such as figure 1 As shown, weaving with this method has the following problems: first, the fabric is easy to wrinkle, shrink after washing, feel rough, poor elasticity, poor abrasion resistance, and a slight itch when wearing, which limits the development of linen fabrics; third 2. Due to the high procurement cost of projectile looms, rapier looms are generally used for weaving, but neither rapier looms nor projectile looms have the highest production efficiency among shuttleless looms, and the machine material consumption is large. SUMMARY OF T...
