Description
Technical field
The present invention relates to a kind of with differential half bleaching linen yarn preparation method is dyed, and belongs to textile industry technology neck
Domain.
Background technique
Traditional half bleaching linen yarn market competitiveness gradually weakens, in order to further open up domestic and international flax market, flax
Differential yarn is conducive to the development and utilization of flax dress-goods, and then promotes the consumption in market.
The long numb colour-spun yarns of existing flax are to dye strip, and then different colors is taken according to a certain percentage
With mixing, it is spun into fiber dyed yarn.Its process flow is long, high production cost；The uniformity for dyeing strip is also poor, and strip is through floating
After white dyeing drying, fibres bond is together, it is more difficult to and close drawing-off；And fiber has a degree of damage, then through simultaneously
Process of roving, forms that fuzzy yarn is longer, and numb particle is more, especially the loss of yarn strength, causes spinning lines dry strong
Power index is relatively low, it is difficult to meet existing tatting requirements of weaving process, hinder the diversity exploitation of product.
Summary of the invention
That the technical problem to be solved in the present invention is to provide a kind of process flows is short, production cost is low, the difference of good spinnability
Change yarn preparation method.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is to provide a kind of flax differential with dyeing half
Float yarn preparation method, it is characterised in that: flax roving is divided into two groups, at two different chemical treatment technologies
Then resulting flax roving after the processing of two different chemical treatment technologies is fed the draft area of spun yarn, through leading by reason simultaneously
It stretches twisting and is spun into single thread, similar SEILE textile (AB yarn), finally drying, winder molding are made to have and dye differential flax
Half drift yarn.
Preferably, the flax roving raw material is formed by scutched flax, then through hackling, at item, drawing process.
Preferably, described two different one of chemical treatment technologies, include the following steps:
Step A1: Asia drift
Flax roving is put into and is boiled in drift equipment, the sodium chlorite of 1.5%-2%owf is added；The nitre of 1%-1.5%owf
Sour sodium；PH value controls between 2.5-3.5, keeps the temperature after heating, and heat preservation terminates drain and is washed to neutrality, completes sub- drift；
