The present invention relates to a kind of production method of medium length type ramie staple, it is that ramie is processed into degummed ramie earlier.Carry out softening, segment, oil supply heap storage, shredding then and make staple.Can be used for common degummed ramie or banded degummed ramie are processed into medium length type ramie staple, for the needs of various weavings.
At present, the production method of general ramie staple adopts long spinning process more, segment after the first shredding, and heap storage again after the segment, and through the multiple tracks combing, therefore, staple of poor quality; In " the Hunan weaving " in January nineteen ninety, published " ramie textile technology is concluded the segment spinning process with exploration-banded degummed ramie " literary composition, banded degummed ramie segment spinning process has been described in the literary composition, its technological process is: banded degummed ramie is carried out softening, segment (130-76 millimeter, the 76-51 millimeter is below 51 millimeters), give shredding (degree of opening is 60-70%), single cylinder shredding, nose eye hired roughneck shredding, sawtooth hired roughneck shredding.Two cylinder slivers and be processed into staple though also mentioned shredding after the first segment in this technological process, carry out repeatedly shredding, and do not design oil supply heap storage zymotechnique, it is straight to be difficult to reason fiber crops after the segment, complex process, the fine loss of fiber crops is very big, and technology does not up till now come true; On " the ramie textile science and technology " in April nineteen ninety, published strain state, Hunan fiber crops cotton mill again about " the segment degummed ramie gives the production practices of a processing " literary composition, the technological process of describing in this article is: degummed ramie is carried out craft pull fiber crops, segment, the oil supply heap storage, shredding and be processed into staple, do not design bruising, staple fibre storehouse after segment, fiber quality is inferior after causing shredding, oneself is estimated in this article: this technology degree of aligning difference is unresolved, can only reach 60% regularity, super over-length fibre and short fibre content height, need textile technology to adapt with it, and this technology can only be applicable to the production short-staple, and applicability is very limited.
Purpose of the present invention just is: the production method to existing ramie staple is improved, a kind of production method of medium length type ramie staple is proposed, to simplify the technological process of medium length type ramie staple, make it more reasonable, improve regularity, the reduction short fiber content of medium length type ramie staple, thereby improve the quality of medium length type ramie staple.
The present invention realizes its purpose like this: promptly the production method of existing ramie staple is improved, promptly method routinely is processed into degummed ramie (or banded degummed ramie) earlier with ramie; Carry out softening then, the long fibre behind the softening carries out dewing oil supply heap storage fermentation process, is cut into the medium length type fiber by the segment process then, directly enters opener again and carries out disposable shredding processing, promptly makes medium length type ramie staple.
The present invention can also realize its purpose like this: segment process (higher limit is in millimeter) is average crimp extension poor of the nominal length of staple and degummed ramie, adds 1 millimeter again.
The present invention also can reach its purpose like this: the nominal length of staple is 60 millimeters and 70 millimeters, and the average crimp extension of its degummed ramie is the 4-7 millimeter.
Further described below in conjunction with drawings and Examples.
Fig. 1 is a process chart of the present invention.
As shown in FIG., ramie is processed into degummed ramie according to a conventional method, carries out softening, then the heap storage of the fine dewing oil supply of the length that is obtained is fermented with CZ141 type softener.The oil of being given is the homemade oil emulsion in our factory, and its prescription is: vegetable oil 7.69%, kerosene 76.92%, oleic acid 11.54%, triethanolamine or Na
2CO
33.85%, its oil content is 1.7～1.9%, also employed product oil in the general oil supply technology of available outsourcing.The heap storage fermentation time: 3-4 days summer, 5-7 days winter, storehouse temperature 25-35 ℃, suitably heating, humidity is 65 ± 5%.Long fibre after heap storage fermentation sends into that segment becomes the medium length type fiber on QD1 (C) the type segment cutter.The higher limit of its segment process (in millimeter) is: the average crimp extension of nominal length and degummed ramie poor, add 1 millimeter again, the nominal length of its staple is 60 millimeters and 70 millimeters, average crimp extension is the 4-7 millimeter, for example: segment process=nominal length-average crimp extension+1=60-6+1=55 millimeter and segment process=70-6+1=65 millimeter.Equally also desirable crimp extension is 4 millimeters or 7 millimeters.Fiber after the segment directly enters CFz001 type opener and carries out disposable shredding, promptly is processed into needed medium length type ramie staple.
Because the present invention has designed above-mentioned production method and process conditions, compares with existing method, technological process is simplified greatly, and more reasonable; Long fine dewing oil supply heap storage fermentation, it is straight to be easy to the reason fiber crops after the segment; The control of segment process rationally guarantees the segment precision, and the medium length type ramie staple principal length that is processed into guarantees in 60 ± 4 millimeters and 70 ± 4 millimeters; Direct disposable shredding processing does not need repeatedly combing shredding after the segment, fibre damage seldom, fiber crops grain and short fiber content reduce greatly, regularity improves greatly, the product qualified rate raising; Production efficiency and product quality also increase substantially.The medium length type ramie staple that is processed into can be used for spinning middle and high yarn; The technology applicability is strong, is easy to promote.Detect through Sichuan Province's examination of fibers office, its performance indications surpass the level of domestic and international medium length type ramie staple of the same trade, and it the results are shown in Table 1.The product testing method adopts GB: GB5881, GB5883, GB5884, GB5886, GB5887, GB5889.
