Description

A kind of half bleaching linen yarn preparation method for having dyeing differential
Technical field
The present invention relates to a kind of half bleaching linen yarn preparation method for having dyeing differential, belongs to textile industry technology neck Domain.
Background technology
Traditional half bleaching linen yarn market competitiveness gradually weakens, in order to further open up domestic and international flax market, flax Differential yarn is advantageous to the development and utilization of flax dress-goods, and then promotes the consumption in market.
It is to be dyed strip that existing flax, which grows numb colour-spun yarns, and then different colors is taken according to certain ratio With mixing, fiber dyed yarn is spun into.Its technological process is grown, and production cost is high；It is also poor to dye the uniformity of strip, strip is through drift After white dyeing drying, fibres bond is together, it is more difficult to and close drawing-off；And fiber has a certain degree of damage, then through simultaneously Bar process of roving, formation fuzzy yarn is longer, and numb particle is more, particularly the loss of yarn strength, causes spinning lines dry strong Power index is relatively low, it is difficult to meets existing tatting requirements of weaving process, hinders the diversity exploitation of product.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of technological process 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 scheme is that providing 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 kinds of different chemical treatment technologies Reason, then the flax roving of gained after two kinds of different chemical treatment technology processing is fed to the draw zone of spun yarn simultaneously, through leading Stretch twisting and be spun into single thread, similar SEILE textile (AB yarns), finally drying, winder shaping, be made to have and dye differential flax Half drift yarn.
Preferably, the flax roving raw material is formed by scutched flax, then through hackling, into bar, drawing process.
Preferably, one kind in described two different chemical treatment technologies, comprises the following steps：
Step A1：Asia drift
Flax roving is put into and boiled in drift equipment, adds 1.5%-2%owf sodium chlorite；1%-1.5%owf nitre Sour sodium；PH value is controlled between 2.5-3.5, is incubated after heating, and insulation terminates discharge opeing and is washed to neutrality, completes sub- drift；
Step A2：Oxygen bleaching
4%-5%owf hydrogen peroxide, 3%-4%owf sodium metasilicate, 4%-5%owf soda ash are added, pH value control exists Between 10-10.5, it is incubated after heating, insulation terminates discharge opeing and is washed to neutrality, completes oxygen bleaching；
Step A3：Post processing
1%-2%owf biological agent is added, pH value is controlled between 7.5-8.5, insulation, and insulation terminates discharge opeing washing To neutrality, post processing is completed.
Preferably, the another kind in described two different chemical treatment technologies, comprises the following steps：
Step B1：Alkali oxygen
Flax roving is put into and boiled in drift equipment, adds 2.5%-3.5%owf sodium hydroxide, 2.5%-3.5%owf Soda ash, 1.5%-2%owf sodium sulfite, 1.5%-2%owf hydrogen peroxide, be incubated after heating, insulation terminate discharge opeing water Neutrality is washed till, completes alkali oxygen step；
Step B2：Oxygen bleaching
5%-6%owf hydrogen peroxide, 1.5%-2.5%owf refining bleaching stabilizer is added, pH value is controlled in 10- Between 10.5, it is incubated after heating, insulation terminates discharge opeing and is washed to neutrality, completes oxygen bleaching；
Step B3：Post processing
1%-3%owf chemical treatments are added, pH value is controlled between 5-7, is incubated after heating, and insulation terminates discharge opeing Complete post processing.
It is highly preferred that in the step A1, initial temperature is 30 DEG C, is warming up to 50 DEG C -60 DEG C, heating rate is 0.7 DEG C/ Min, soaking time 30min-60min.
It is highly preferred that in the step A2, initial temperature is 50 DEG C, is warming up to 90 DEG C -95 DEG C, soaking time 40min- 60min。
It is highly preferred that in the step A3, -60 DEG C of temperature 50 C, soaking time 60min-90min.
It is highly preferred that in the step B1, initial temperature is 50 DEG C, is warming up to 95 DEG C -98 DEG C, heating rate is 1.5 DEG C/ Min, soaking time 40min-60min.
It is highly preferred that in the step B2, initial temperature is 50 DEG C, is warming up to 90 DEG C -95 DEG C, heating rate is 1.5 DEG C/ Min, soaking time 40min-60min.
It is highly preferred that in the step B3,90 DEG C -95 DEG C are warming up to, soaking time 10min-20min.
Flax roving is carried out two kinds of different chemical technologies and handled by the present invention, after then two kinds of different process are handled Rove carries out sirospun production resultant yarn, due to being single thread that two kinds of different chemical processing schemes rove are spun into through draw twisting, makes It is also variant to the absorption property of dyestuff into yarn, after dyed, form the differential yarn that Adjacent color spins style.
The present invention is improved on the basis of the production equipment of traditional half bleaching linen yarn and chemical treatment method, is spun Make with differential half bleaching linen yarn is dyed, after dyed, there is yarn color to spin style, but bar is dry, strength, filoplume are excellent Numb colour-spun yarns are grown in flax, and colorimetric spinning technological process is short, and production cost is low, good spinnability.New differential flax Yarn, line product category is expanded and enriched, suitable for yarn dyeing and piece dyeing finishing, be available for strong, the fabric of weaving selectivity Unique style, there are the stronger market competitiveness and preferable market prospects.
