Description
Technical field
The present invention relates to textile technology field, be specifically related to the irregular regulate and control method of a kind of fineness of yarn.
Background technology
Along with the development in market and improving constantly of the level of consumption, people are also increasingly high to the requirement of cotton product kind and quality, and this just makes cotton quality in processing, use and trade, more and more come into one's own.Cotton fiber length and distribution thereof are the important evidence of confirming cotton quality, processing technology and product quality; Be commerce and trade always, problem that manufacturing enterprise was concerned about; Especially along with the combing high grade yarn applies to weaving of shirt, knitted underwear more and more; Make manufacturer pay close attention to the distribution situation of cotton fiber length more, and to the situation that influences of product quality, or even economic benefit of enterprises is influenced situation also receive much attention.
Yarn unevenness is the primary index of decision cotton yarn class, and frivolous high-grade fabric requires high to the cotton yarn evenness.Yet for many years, because of lacking the control measures of science, how the irregular regulation and control of yarn are undertaken by experience, are difficult to regulate and control accurately, and randomness is very big.What this area was commonly used " had not both had the yarn unevenness computing formula in the cotton spinning handbook technical data such as " cotton-spinning quality controls ", the concrete irregular regulate and control method of yarn was not provided yet.Carrying out the irregular regulation and control inaccuracy of yarn by experience, is not that to waste raw material be exactly that the yarn qualities produced is poor.Bibliographical information such as " based on the irregular prediction of the yarn of fiber alignment parameter ", " analysis of cotton uneven fineness characteristic " a kind of Forecasting Methodology of fineness of yarn irregularity; For the solution of this problem provides some theoretical foundations; But its operability is not strong, is difficult in production practices, use.
Summary of the invention
The technical problem that the present invention will solve has provided the irregular regulate and control method of a kind of accurate and reliable fineness of yarn, can avoid wastage of material and can improve yarn qualities.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
The irregular regulate and control method of a kind of yarn may further comprise the steps:
(1) contrast contract or relevant criterion (GB/T398-2008 " cotton grey yarn ", or USTER statistical value), predetermined yarn linear density is N
Ty(tex) the irregular coefficient of variation of fineness of yarn is intended control value C;
(2) according to spinning equipment system and spinning kind confirm yarn process structure parameter beta (characterize fiber in yarn random alignment to the influence of yarn unevenness,, unit mm relevant with spinning equipment system, state of the art, spinning kind).Method is by insertion, and by the selected β of table 1, (as: 4～10tex), the β that line density greatly then selects is big, and the β of the little then choosing of line density is little, can be drawn by insertion computing formula (I) with the shelves line density for yarn;
