Example Embodiment

[0014] Example 1

[0015] Shake the cone into a skein. The circumference of the skein is 130 cm. The weight of each skein is 95 grams. To prevent over-tight skein, any over-tight should be removed and loosened again. In order to prevent the difficulty of arranging the yarn after entering the machine, you can add a few more twists to the hank. After entering the machine, straighten the yarn and wrap the skein on the mercerizing roller. The yarn should be smooth and even to prevent overlap.

[0016] The mercerizing roller is tightened and tensioned. The tensioned frame length is 130 cm. Then the tensioned skein is soaked in liquid ammonia, the mercerizing roller rotates, and the skein is pressed between the mercerizing roller and the roller. The ammonia immersion time For 15 seconds, the ammonia immersion temperature is -33 degrees Celsius. Shake the treated hank yarn in a liquid ammonia spin-drying cylinder to remove excess liquid nitrogen, and then soak it in water at a temperatu...

[0017] Example 2:

[0018] The invention is used to process 2000 metric linen yarn (100% flax), the cone yarn is shaken into a skein, the circumference of the skein is 135 cm, each skein weighs 95 grams, and 2-4 threads are tied to the skein. After entering the machine, put the hank on the mercerizing roller in turn, requiring uniformity and no overlap. Tension is applied to the hank on the mercerizing roller and immersed in liquid ammonia for 45 seconds under rotating conditions. The mercerizing roller and the roller are matched to squeeze the hank of liquid ammonia. The temperature of the liquid ammonia is -32 degrees, and then the tension is removed. Lower the skein, soak it in water at 55 degrees Celsius, soak for 45 seconds and then spin dry until the water content is 50%, then place it in a circulating hot air stream at a temperature below 65 degrees Celsius for drying. Out of the machine when the moisture is less than 10%. The hank mesh is made into a tube shape or direc...

[0019] Example 3:

[0020] Using the present invention to process 32 British counts of pure cotton mercerized yarn, 32 counts of pure cotton yarn (100% cotton) cone yarn, each twisted 75 grams, shake into a hank, with a circumference of 132 cm, which can tie the hank twice After entering the machine, put the skein on the mercerizing roller in turn, requiring uniformity and no overlap. Tension is applied to the hank on the mercerizing roller and immersed in liquid ammonia for 50 seconds under rotating conditions. The mercerizing roller and the roller are matched to squeeze the hank of liquid ammonia. The temperature of the liquid ammonia is -34 degrees Celsius, and then the tension is removed. Take off the hank and soak it in water at 55 degrees Celsius. After soaking for 50 seconds, spin dry until it contains 60% water. Then place it in a circulating hot air stream. The temperature is below 70 degrees Celsius for drying. When it is less than 12%, the hank mesh is made into a tub...

Abstract

The invention relates to a mercerized yarn liquid ammonia treatment method, which is a plant fiber modification method through liquid ammonia treatment. With the method, gloss, softness, and smooth texture of the plant fiber are improved. The mercerized yarn liquid ammonia treatment method comprises the processes of: yarn arranging, yarn lapping, ammonia soaking, water washing, spin-drying, and bake-drying. Before ammonia soaking, a mercerizing roll is tensioned, such that tension is increased. During the ammonia soaking process, the yarn is rolled by using the mercerizing roll and a rolling roll. The method provided by the invention is mainly used in modifications of pure yarns and blended yarns of hemp, flax, ramie, cannabis sativa, apocynum, viscose fiber, and other cellulose fibers. The method can also be used in modifications of blended yarns of the plant fiber and fibers such as chemical fiber, wool, and silk.

Description

technical field [0001] The invention relates to a method for treating mercerized yarn with liquid ammonia, which modifies plant fibers to increase luster, softness and smoothness. Background technique [0002] The theoretical research on the liquid ammonia processing technology system of textiles began in the 1930s, and it was officially put into industrial production in the 1970s. The liquid ammonia processing technology was first developed in Norway in 1963 by Dexter Risa University and the Norwegian Central Industrial Research Institute. At that time, it was only a technology of finishing yarns by hand to replace yarn mercerizing. Due to the strong permeability of liquid ammonia to cotton fibers, the ammonia liquid remaining on the yarn is easier to remove than lye, and has a better mercerizing effect than liquid lye, so it has been paid attention to. [0003] For the alkaline mercerizing treatment method of cotton and linen fibers, there are problems such as high recov...
