Embodiment Construction

[0014] ① Pre-treat the pure hemp yarn first, and remove most of the hemp grains, knots, thick spots, etc. on the yarn through a yarn clearer.

[0015] ②High-pressure, high-temperature steaming, place the yarn count in a large-capacity shrinking machine, at a temperature of 90°C, and steam at three steam pressures for 70 hours.

[0016] ③ Wax the yarn count, wax the yarn with a wax disc on the winder, the weight of the wax disc is 3 times that of the No. 58 neutral industrial white wax used, to increase the contact surface between the yarn count and the wax, and wax evenly.

[0017] ④Needle knitting, knitting by knitting machine.

[0018] ⑤ Sewing, sweater sewing machine sewing, supplemented by lockstitch sewing machine and overlock sewing machine, the number of stitches per temple is not less than 8-9 stitches.

[0019] ⑥ For softening treatment, use a large-capacity vertical washing machine with a bath ratio of 1:15 at a water temperature of 95°C, steam for 5 hours, and then...

Abstract

The production method of pure hemp shrinkproof soft knitwear includes the following steps: Yarn pretreatment, high-pressure high-temp. steaming, yarn parafining, knitting, sewing, softening treatment, baking and high-pressure ironing setting. Said invented knitwear has the functions of inhibiting bacteria, mildew-proofing, preventing of corrosion, odour-resisting, resisting radiation, resisting UV ray and resisting static electricity.

Description

1. Technical field: [0001] The invention belongs to the technical field of pure hemp knitting, and in particular relates to a method for manufacturing pure hemp shrink-resistant soft knitted fabrics. 2. Background technology: [0002] At present, in the field of domestic hemp knitting products, ramie and flax are the main products, and pure hemp knitwear has not been reported, which makes it difficult to fully reflect the advantages and characteristics of hemp products. The characteristics of adding hemp fiber are better than other products. Hemp fiber, how to utilize pure hemp woven yarn without adding any auxiliary materials to produce pure hemp knitted fabrics has become a research topic for people. 3. Contents of the invention: [0003] The problem to be solved by the present invention: pure hemp yarn: the yarn count is stiff and inelastic, the twist is tight, the rigidity is large, the surface of the yarn count is rough and not smooth, and there are many grains, knots...
