Abstract
The invention relates to the field of the spinning technology and provides a novel high-count pure cotton hard twisted yarn setting technology. The technology includes the following steps that high-count pure cotton hard twisted yarn is subjected to liquid ammonia treatment, and the yarn is fed in an intermittent or continuous mode; according to the processing process, the temperature of liquid ammonia is -31.8 DEG C, dipping lasts for 8-9 s, the drying temperature is increased from 50 DEG C to 120 DEG C and is kept for 20-30 min after being gradually increased to 120 DEG C, the ultra-high twist of the yarn is stabilized after washing, drying and roasting, under the constant-temperature constant-humidity environment with the temperature being 20+/-2 DEG C and the relative humidity being 65+/-2%, after pre-equilibration treatment is carried out for 24 h, a yarn twist set-twist efficiency test is carried out, and the average set-twist efficiency is 50-55%. The technology has the advantages that by means of a physical processing method, the ultra-high twist of the high-count pure cotton hard twisted yarn is set, the weaving ability of the yarn on a machine is obviously improved, and productivity and product quality are greatly improved.
Description
Technical field
The invention belongs to spinning process field, especially relate to a kind of novel high-count pure cotton tight twist yarn setting process.
Background technology
In recent years, " wrinkle " hot blast wasted domestic and international market, and especially high-count pure cotton wrinkle series products enjoys favor especially.But there is high difficulty in the production process of this series products, purified cotton high grade tight twist yarn is in whole production process, especially there is high difficulty in sizing operation, often because the superpower twist of heavy twist yarn causes sizing failure, or loom efficiency is on the low side, increase the probability of fabric defect, properties of product and style are affected.
Purified cotton high grade tight twist yarn tradition setting process, normally before sizing, first carries out special winding process, the bobbin of tight twist yarn is wound as the large eye plastic cement bobbin of 1.5 ~ 2.5cm thickness, has special requirement to the rolling thickness of cheese and the selection of bobbin.Then the purified cotton high grade tight twist yarn bobbin meeting winding requirement is put into High Temperature High Pressure Boiler Temperature with rational marshalling.Next damp and hot yarn steaming technique is carried out.First the cold air in Boiler Temperature is drained emptying, then continuous heating, when temperature reaches 105 DEG C (± 3 DEG C), make it stablize and keep 180min.Then make yarn reduce pressure cool and prepare follow-up warping, sizing operation.All processes needs 3 hours usually, and extremely consumption accounts for the time.Often there will be twist shaping in the process undesirable, warping process is sizing operation unpassable situation especially, is a bottleneck difficult problem for this series products all the time, does not break through simultaneously.
Summary of the invention
The object of this invention is to provide a kind of novel high-count pure cotton tight twist yarn setting process.
For realizing above-mentioned goal of the invention, technical scheme of the present invention is as follows:
A kind of novel high-count pure cotton tight twist yarn setting process, comprises the steps:
Purified cotton high grade tight twist yarn is carried out Liquid Ammonia Treatment, in Liquid Ammonia Treatment process, the mode of yarn feeding is batch (-type) or continous mode, processing procedure is: liquefied ammonia temperature is-31.8 DEG C, dip time is 8 ~ 9s, bake out temperature is elevated to 120 DEG C from 50 DEG C, temperature progressively raises, 20 ~ 30min is incubated after being elevated to 120 DEG C, then through washing, dry, after baking, the superpower twist of yarn is settled out, the whole Liquid Ammonia Treatment time is for being less than or equal to 1h, finally, be (20 ± 2) DEG C in temperature, relative humidity is under the constant-temperature constant-humidity environment of (65 ± 2) %, after pre-equilibration process 24h, carry out the dead twist efficiency test of yarn twist, average dead twist efficiency reaches 50% ~ 55%.
The advantage that the present invention has and good effect are: the way adopting Physical Processing, the superpower twist of purified cotton high grade heavy twist yarn is shaped, first, there is no special requirement at winding procedure, conventional sebific duct bobbin can be adopted, facilitate the management of winding process; Secondly, Liquid Ammonia Treatment is carried out to purified cotton high grade tight twist yarn, batch (-type) and continous mode two kinds of methods can be adopted, depending on physical device and the condition of production of enterprise; After the Liquid Ammonia Treatment time of regulation, fast the superpower twist of yarn stablized and send airtight filling, not affecting and carry out follow-up warping, slashing technique, from the time general one hour, obviously will be better than traditional handicraft; 3rd, in conventional wet heat setting process, yarn often can cause the problems such as yarn yellowing because of the globule of wet-hot steam, adopts new treatment process not deposit analogue; Finally, unstable for the twist of yarn trend well can well be settled out, greatly be conducive to follow-up preparation and looming weaving.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described, but do not limit protection scope of the present invention.
