Abstract
The invention discloses a flax mulberry bark fiber blend dyeing knitting yarn. Raw materials of the yarn comprise 75-90% of flax fiber and mulberry fiber as the balance by weight. The root tip splitting degree difference of the flax fiber body is less than 100, the blended splitting degree difference is less than 50, strength difference is less than 20N, and the length difference is less than 10cm. A manufacture method of the flax mulberry bark fiber blend dyeing knitting yarn is further provided. The flax mulberry bark fiber blend dyeing knitting yarn has the advantages of being good in dye-uptaking rate, bright in color, good in air permeability, rapid in radiating performance, soft, smooth and not close-fitting. The manufacture method of the flax mulberry bark fiber blend dyeing knitting yarn is short in process flow, saves energy, reduces emission, and is good in manufactured knitting yarn quality and low in cost.
Description
Technical field
The present invention relates to the stocking yarn field, be specially the stocking yarn of mulberry fibre blend dyeing and preparation method thereof that grows flax.
Background technology
Flax is one of textile raw material, in natural fabric, it is unique bundle fiber, spindle structure and unique pectic substance hypotenuse hole with natural fabric, therefore linen fibre has the characteristics such as gas permeability, hygroscopicity, salubrious property and hydrofuge, and flax textile is by the product title titled with " can general breathing ".Since the last century the eighties, along with the rise of natural fabric, flax textile is more comfortable, well-pressed than textiles wearability such as ramie, hemp, bluish dogbanes, and tone is soft generous, and feel is more smooth.Be the impetus of rapid growth in the market comsupton of linen knitting yarn in recent years wherein, the market demand is very large, and designs and varieties are also along with weeding out the old and bring forth the new.
Stocking yarn except will reaching the desired indices of common spun yarn, requires also that soft yarns, high resilience, filoplume are few, bar dried uniformity, especially slubbing will lack, the knitting production after being beneficial in its process.But the linen fibre rigidity is large, and fiber is coarse, hard; Simultaneously, dye on the linen fibre that efficient is low, color and luster is bright-coloured not, so the vividness of finished product is influenced.At present also without any studying or report the blending product that mulberry fibre and flax are arranged.
In addition, traditional resultant yarn dyeing flow is complicated, at first will make linen thread and yarn, then linen thread and yarn is dyeed.That is: A, make yarn first: flax comb growth fiber crops → combo → 0 also → head also → in the lump → two also → three also → end also → roving boiling and bleaching → spun yarn → drying → tight cylinder doff → surely weigh packaging and warehousing.B, become dyeing yarn afterwards: resultant yarn metal (or fall strand) → dress yarn → partly float yarn preliminary treatment (soda boiling) → 2 times → acid neutralization washing → inferior chlorine of washing floats yarn → dechlorination → 2 times → hydrogen peroxide of hot water washing and floats the doff of yarn → deoxidation enzyme washing processings → hot water wash → cold wash → dyeing → dehydration → (opening yarn) → drying → tightly → surely weigh packaging and warehousing or enter next process, and one has 17 procedures; Provide flow process short, simpler preparation method, become another pursuit of people.
Summary of the invention
For solving above problem, the invention provides a kind of good permeability, flax mulberry fibre blend dyeing stocking yarn that cost is low and directly in intermediate link roving boiling and bleaching operation, dye, directly spin dyed yarn at fine spining machine afterwards, flow process is short, the preparation method of energy-saving and emission-reduction.
The invention provides a stocking yarn that grows flax the mulberry fibre blend dyeing, its raw material of content meter consists of by weight: linen fibre: 75～90%, surplus is mulberry fibre, the root tip division degree difference of described linen fibre itself is no more than 100, the division degree difference that is mixed is no more than 50, strength difference is no more than 20 newton, and difference in length is no more than 10 centimetres.
In the stocking yarn of flax mulberry fibre blend dyeing of the present invention, the percentage that described linen fibre weight content accounts for raw material is: 75～90%.
As the preferred technical scheme of the present invention, in the stocking yarn of described flax mulberry fibre blend dyeing, the percentage that described linen fibre weight content accounts for raw material is: 80～85%.
The invention discloses a preparation method of stocking yarn who grows flax the mulberry fibre blend dyeing, may further comprise the steps:
(a) determine the blending rate of described linen fibre and mulberry fibre, wherein, its raw material of content meter consists of by weight: linen fibre: 75～90%, and surplus is mulberry fibre, through being mixed combo, passes through roving boiling and bleaching after being spun into living rove again;
(b) rove half deguming: pickling, Compound-acid (the weight score: oxalic acid: sulfuric acid=2:8 that adds 2.5～3.5g/l, wherein, sulfuric acid concentration is no more than 80%) and bleeding agent, the pickling temperature of 2～3g/l be: 28～32 ℃, pickling time are: 30～35 minutes;
(c), the inferior chlorine that adds 0.5～2g/l bleaches, bleaching temperature is: 45～50 ℃, bleaching time are: 40～45 minutes;
Add 1～1.5g/L sodium sulfite dechlorination, the dechlorination temperature is: 45～50 ℃, dechlorination time are: 10～15 minutes;
Add 50～55 ℃ of hot water and wash, washing time is 10 minutes;
(d) dye front biology enzyme preliminary treatment: add the compound bio degummase (weight score: lignoenzyme: 3～4.5 g/l of pectase=1:2), 50～60 ℃ of lower insulations 30～40 minutes, handle rear discharge opeing;
(e), dyeing: the percentage by weight that adds the need dyed yarn is 4～6% dyestuff; Be warming up to 60 ℃; Circulated 15～20 minutes; Salt adding: 20～25 g/l, glauber salt: 15～20 g/l; Circulated 10～15 minutes; Salt adding: 20～25 g/l, glauber salt 15～20 g/l; Circulated 10～15 minutes; Salt adding: 20～25 g/l, glauber salt: 15～20 g/l; Circulated 20～25 minutes; Add the soda ash fixation; Circulated 30～40 minutes; Cold wash: duration 10～15 minutes; Adding neutralizer selects under HCA:1.5～2.5 g/l, duration 20～25 minutes, the normal temperature;
(f) wet spinning obtains spun yarn, carries out the rear tight cylinder doff of drying and gets finished product.
In the preparation method of short flow process flax mulberry fibre blend dyeing stocking yarn of the present invention, rove yarn twist factor is 0.22～0.24.
In the preparation method of flax mulberry fibre blend dyeing stocking yarn of the present invention, the spun yarn twist factor is 0.85～0.9.
The present invention has following beneficial effect: the invention provides a stocking yarn that grows flax the mulberry fibre blend dyeing, with two kinds of fiber blends, reach mutual supplement with each other's advantages, have a dye-uptake good, bright in colour, have advantages of again good permeability, rapid heat dissipation, smooth not next to the skin; The invention provides a stocking yarn manufacture method that grows flax the mulberry fibre blend dyeing, flax spinning will be through the boiling to float just and can be spun into spun yarn of rove, and the dyeing of blended yarn is directly carried out after floating boiling, and just saved 17 procedures, and flow process is brief; Iterative process when processing has not simultaneously had, and has just reduced use and the use of water, the i.e. energy-saving and emission-reduction of chemical industry material yet; Link in the middle of saving has also just protected fiber impaired, and quality better ensured, yarn quality is good; Economize operation and namely economize expense, so reduced cost.Process through enzyme again before the dyeing; it is the selectivity of utilizing biology enzyme; make it under suitable temperature conditions, decompose, remove the impurity in the rove that affects rove dyeing; simultaneously; because biology enzyme is relatively gentleer to cellulosic effect; thereby in processing procedure, can protect cellulose, and not damage fiber.
