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
The present invention relates to a kind of mercerising yarn liquid ammonia treatment process, make the string modification increase gloss, pliability and slipping by processing.
Background technology
The liquefied ammonia process technology systems theory research of textiles starts from the thirties in 20th century, and formally throwing people's industry production is at 20 century 70s.At first in 1963 Norway by the De Kesi tal fibre in Sha university and Norway central industry research institute joint development the liquefied ammonia processing technology.At that time also just from the yarn finish staff, to substitute the technology of yarn mercerization finish.Because the Liquid Ammonia on Cotton fiber has extremely strong permeability, the ammoniacal liquor that remains on yarn is more easily removed than alkali lye, and better than liquid caustic soda mercerization effect, thereby is paid attention to.
For the alkaline mercerization finish method of cotton fibriia, have the problems such as cost recovery height of alkali, and the mercerization finish method of alkali there is significant limitation for the processing mode take yarn as object.
Summary of the invention
The purpose of this invention is to provide a kind of mercerising yarn liquid ammonia treatment process, can improve the quality of mercerising yarn, reduce processing cost.Above-mentioned purpose realizes by following technical scheme:
Line yarn liquid ammonia treatment process, its composition comprises: reason yarn, cover yarn, after carrying out described cover yarn, yarn is soaked ammonia, then wash, dry, dry.
Described liquid ammonia treatment process for skein, it is described that to soak the ammonia time be 5 to 20 seconds, the temperature of soaking in the ammonia place is-31 to-35 degrees centigrade.
Described mercerising yarn liquid ammonia treatment process before described yarn soaks ammonia, is tightened the mercerising roller and is added high tension, and make mercerising roller and roll roll compacting yarn in soaking the ammonia process.
Processing method provided by the invention has following beneficial effect:
1, mercerising yarn liquid ammonia finishing technology provided by the invention, can use through the yarn of liquid ammonia finishing and make various textiles, adapt to current piece market small lot, many kinds, the characteristics of single-piece personalized consumption even, ageing height, the development trend that meets the liquid ammonia finishing technology, the present invention will progressively replace the liquid ammonia finishing technology for cloth, thereby makes product of the present invention account for the leading position in market.
2, the yarn of processing through the present invention, fragility reduces, and dyeability is good, can weave the work of high quality of various different patterns.
3, through the yarn of technical finesse of the present invention, weaving efficiency obviously improves with the quality that becomes cloth.Technology of the present invention is given cloth that these yarns are made into good rear arrangement performance, has improved the dyeability of this yarn, can also use knitwear and textiles that this technology creates how brand-new cotton fibriia cellulose fiber.
4, the present invention can process large batch of yarn fast, low, the little problem in batches of production efficiency when changing yarn treatment in the past, make the liquid ammonia finishing technology can be on a large scale, wide popularization and application cheaply.
5, the yarn of the cellulose fibres such as linen-cotton of process the present invention processing, changed easily wrinkling, easy contracting of fabric, the bad shortcoming of dyeability that yarn is made into, makes fabric can increase silky gloss, soft, fluffy, smooth feel.
The specific embodiment
Embodiment 1
The cylinder yarn is shaken into reeled yarn, and the girth of reeled yarn is 130 centimetres, and the weight of every reeled yarn is 95 grams, prevent the twisting tied of tension, everyly runs into should removing of tension, from Xin Songzha.For preventing managing the yarn difficulty after entering machine, reeled yarn can be added the binding of several roads.After entering machine, yarn is made in order, reeled yarn is enclosed within on the mercerising roller, cover is smooth, even during yarn, it is overlapping to prevent.
The mercerising roller is tightened added tension force, the frame length that adds tension force is 130 centimetres, then the reeled yarn of tightening is entered in liquefied ammonia and soaks, and the mercerising roller rotates, and by roll compacting, soak the ammonia time is 15 seconds to reeled yarn between mercerising roller and roll, soaks the ammonia temperature and is-33 degrees centigrade.Treated reeled yarn is got rid of unnecessary liquid nitrogen in the liquefied ammonia drying tube, then it is soaked in water, water temperature 60 degree Celsius, remove liquefied ammonia remaining in yarn, then drying yarn moisture content 50% just can, then remove contained residual moisture in oven dry or microwave under the physical condition of high temperature, then go out machine, shake into a yarn or directly with the processing of dyeing of reeled yarn state.
Embodiment 2:
The present invention for the treatment of 2000 public count linen yarns (flax 100%), is shaken into reeled yarn with the cylinder yarn, 135 centimetres of reeled yarn girths, each reeled yarn weight 95 gram is pricked the 2-4 diatom to reeled yarn, after entering machine, successively reeled yarn is enclosed within on the mercerising roller, requires evenly, not overlapping.Add tension force at the mercerising roller for reeled yarn, and immerse in rotating condition 45 seconds of liquefied ammonia, mercerising roller and roll coordinate the reeled yarn for liquefied ammonia to carry out roll compacting, and the temperature of liquefied ammonia be-32 to spend, then remove tension force, take off reeled yarn, be immersed in water, water temperature is 55 degree Celsius, soak and dried afterwards in 45 seconds, until moisture 50%, then place it in the thermal current of circulation, temperature is dried below 65 degree Celsius.Go out machine at moisture less than 10%.The reeled yarn net is become tubular or be directly used in dyeing processing.
Embodiment 3:
Use the present invention to process 32 English Zhi Chunmian mercerized yarns, with 32 purified cotton yarns (cotton 100%) cylinder yarn, every strand 75 grams shake into reeled yarn, 132 centimetres of girths can be pricked 2 diatoms to reeled yarn, after entering machine, successively reeled yarn is enclosed within on the mercerising roller, requires evenly, not overlapping.Add tension force for reeled yarn on the mercerising roller, and immerse in rotating condition 50 seconds of liquefied ammonia, mercerising roller and roll coordinate the reeled yarn for liquefied ammonia to carry out roll compacting, the temperature of liquefied ammonia is-34 degrees centigrade, then remove tension force, take off reeled yarn, be immersed in water, water temperature is 55 degree Celsius, soak and dried afterwards in 50 seconds, until moisture 60%, then place it in the thermal current of circulation, temperature is dried below 70 degree Celsius, the reeled yarn net is become tubular at moisture less than 12% the time or is directly used in dyeing processing.
