Production method of flax knitted fabrics

Abstract

The invention discloses a method for manufacturing knitted flax fabrics, which comprises the following steps of treatment of weft yarns before weaving, weaving on a machine, and after-treatment. Firstly, flax yarns between 28 and 42 n / 1 are steamed in a steam box for 60 to 90 minutes at a temperature of between 90 and 100 DEG C, subjected to heat preservation for 50 to 60 minutes, and woven on a bodkin plain circular knitting machine between 16 and 18 GG, wherein the vehicle speed is set to between 10 and 20 rpm, and the yarn feeding tensile force is between 5 and 6 g; and secondly, fabrics are subjected to rope chromating, and the finished products - the knitted flax fabrics with a weight of 190 grams per square meter are finally obtained. Therefore, the flax fabrics woven by the circular knitting machine have the advantages of soft hand feeling, good elasticity and good air permeability; and the method effectively reduces tears of the fabrics during the weaving process of the circular knitting machine and makes weaving and looping formation become smooth, so that the method reduces the defective rate during the process of mass production.

Description

technical field [0001] The invention relates to a production method of linen fabric, in particular to a production method of linen knitted fabric, belonging to the technical field of knitting. Background technique [0002] At present, flax fabrics are usually woven by weaving technology. Specifically, according to the number of warp yarns required by the process, the cheeses are arranged accordingly and warped on the warping machine. On the loom, the package yarn is installed on the weft frame of the loom, the weaving process parameters are adjusted, and the rapier loom is started to realize the interweaving of warp and weft yarns to form a flax woven fabric. Due to the wide adaptability of the rapier loom, the flax material is completely suitable for use in rapier looms. Smooth weaving on the rod loom, so the weaving process of flax is widely used in the field of weaving. However, due to its weak elasticity and insufficient softness, the woven linen fabric ranks lower in t...

AI Technical Summary

Problems solved by technology

However, due to weak elasticity and insufficient softness, linen woven fabrics are of a lower grade in the market.

[0003] For this reason, the industry turns to try to weave linen fabrics on circular knitting machines. The flax fabrics woven by circular knitting machines have the characteristics of soft hand feeling, good elasticity, good air permeability and not easy to wrinkle. Due to its brittle characteristics, it is not easy to bend the yarn into loops during the weaving process, and the yarn is prone to holes during the process of stripping and looping, resulting in a high rate of defective products, which cannot meet the quality requirements of customers. On the other hand, Due to the poor spinnability of linen yarn, unevenness and slubs are also the cause of holes in the weaving process.
