Problems solved by technology

In the prior art, due to the actual production situation and the low content of cellulose in flax fiber, the improvement methods described in many papers using cellulase polishing and resin setting are not the best, mainly because the strength drops very obviously , the shrinkage is unstable and cannot meet the needs of customers

Embodiment

[0042] This embodiment provides a method for making a linen knitted fabric, which is used to make a single-sided plain linen knitted fabric with a finished product width of 54 inches, a finished product grammage of 230 GM, a CPI=44, and a WPI=32, such as figure 1 shown, including the following steps:

[0043] Step 1: Select 28NM / 1 flax knitting special yarn to loosen the tube, wrap socks into the vat to infiltrate and soften the flax raw yarn, place the flax raw yarn in a temperature of 100°C and a concentration of 1.5g / L Refining penetrating agent LCF-185 (LCF-185 is a product produced by Taiwan Fuying Chemical Technology Co., Ltd.) and boiled for 20 minutes, then put the boiled raw yarn into polyethylene wax with a temperature of 45°C and a concentration of 3g / L Soak in softener P250 (P250 is a product produced by Baiderui Textile Auxiliaries Co., Ltd.) for 20 minutes, and dehydrate it out of the cylinder;

[0044] Step 2: Carry out high-frequency drying treatment on the pe...

Abstract

The invention provides a method for manufacturing flax knitted fabric. The method comprises the following steps: performing osmotic super-softening treatment on flax grey yarns; performing high-frequency drying treatment on the flax grey yarns after being subjected to osmotic super-softening to enable the moisture content of the grey yarns to be 15-20 percent; performing spooling waxing treatment on the flax grey yarns after being subjected to high-frequency drying, and keeping the moisture content of the grey yarns 15-30 percent; weaving the waxed and sealed flax grey yarns to obtain grey cloth; performing two-sided singeing treatment on the obtained grey cloth; performing liquid ammonia mercerization on the grey cloth after being subjected to the two-sided singeing treatment, and then, performing neutral super-softening treatment; calendaring the grey cloth after being subjected to neutral super-softening, and setting and preshrinking by using a hydrophilic softener to obtain the flax knitted fabric. According to the method for manufacturing the flax knitted fabric provided by the invention, the yarns can be softened, faulty products can be reduced, the efficiency and the quality of knitting can be improved, and the wearability of the fabric can be improved while good breathable moisture absorption and mold resistance of the flax knitted fabric are kept.

Description

technical field [0001] The invention relates to a production method of linen knitted fabric, which belongs to the technical field of textiles. Background technique [0002] As a recognized natural and environmentally friendly fabric, linen is favored due to its advantages of moisture absorption, crispness, coolness, and high strength, but its application in the field of high-end quilts is developing slowly. [0003] In the prior art, flax products are mostly woven products, and knitted products are developed late. This is because the basic structural unit of knitted fabrics is a coil, and the yarn bends frequently in the fabric, while flax yarn has high rigidity, rough and hard fibers, The defects of poor elongation and poor elasticity make the flax yarn poor in knitting performance in the knitting process. [0004] Although in recent years, breakthroughs have been made in the flax spinning process, and high-count yarns suitable for the knitting process have been developed,...
