Description
Technical field
The present invention relates to linen textile technology fields, and in particular to a kind of linen textile technology of low percentage of impurity.
Background technique
Linen be with flax fiber spin come yarn.Flax fiber is the natural fiber that the mankind use earliest, is day
Unique beam plant fiber, has natural spindle-type α-Fe2O3 and unique pectic substance bevel edge hole, thus generates in right fiber
The characteristics such as excellent moisture absorption, ventilative, anti-corrosion, antibacterial, low electrostatic, make sodolin become the fabric for capableing of general breathing, are praised
For " fiber queen ".Under room temperature, wearing flax clothes can make the effective temperature of human body decline 4 degree of -5 degree, therefore flax is known as again "
Natural air conditioner " good reputation.Again because flax is a kind of rare natural fiber, the 1.5% of natural fiber is only accounted for, so flax product valence
Lattice are relatively expensive, become identity and status symbol in foreign countries.
Flax fiber textile has good healthcare function.It has unique inhibition bacterial action.Linum Yin Xiang section
Plant can distribute a kind of indistinct fragrance.Expert thinks that this smell can kill many bacteriums, and can inhibit a variety of helminths
Growth.Proved with the scientific experiment that contact method is done: lingerie has significant bacteriostasis, and to Pseudomonas aeruginosa, white is read
The bacteriostasis rate of the international standards bacterial strain such as pearl bacterium exceeds the bacteriostasis rate of Escherichia coli and gold-coloured staphylococci pearl up to 65% or more
90% or more.The mummy of ancient egypt Pharaoh is rolled in surprising solid fine linen, be allowed to completely to save to
It is modern.The heat dissipation performance of flax is splendid, this is because flax is unique bundle fiber in natural fiber.Bundle fiber is slender by flax
Born of the same parents are sticked together by colloid to be formed, and because it is not more there are the condition of air, the ventilative ratio of sodolin is up to
25% or more, thus its heating conduction (gas permeability) is splendid.And skin surface temperature can be effectively reduced rapidly.Flax fiber
Straight bright and clean, in 50 times or more of amplification projection, it is distorted as a section section bamboo without cotton, wool fibre etc..This feature makes
The textile of subtle dust or dirt in product can be easy to remove because dust can not find hiding-place.
The mankind by ultraviolet irradiation, can damage body for a long time.And the hemicellulose contained in linen textile product is to inhale
Receive the optimisation substance of ultraviolet light.Hemicellulose is actually still immature cellulose.The hemicellulose that flax fiber contains exists
18% or more, several times are higher by than cotton fiber.When it becomes clothing, skin can protect from the injury of ultraviolet light.Linen is knitted
Object can be reduced the perspiration of human body than other fabrics, the absorption speed of flax textile than silks and satins, rayon fabric, even compare cotton
It is several times fast.In the prior art, sodolin is easy corrugation, and the percentage of impurity of linen is not easy to control, leads to sodolin
Unstable quality, and the process of pretreating linen yarn not only influences the product quality of sodolin, has an effect on subsequent dyeing and finishing work
Skill.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of linen textile technology of low percentage of impurity,
Solve the problems, such as linen percentage of impurity height, sodolin unstable quality in the prior art, the linen being prepared is containing miscellaneous
The sodolin quality that rate is low and weaving obtains is stable, function admirable.
The purpose of the present invention is achieved through the following technical solutions:
A kind of linen textile technology of low percentage of impurity, includes the following steps:
Step 1: first time health and cotton cleaning process processing are successively carried out to flax fiber, it is artificial to reject flax knot and overlength fibre
Then dimension carries out cutting fiber crops processing and obtains dry fiber crops, dry fiber crops are carried out at cotton carding, combing, drafting, rove and second of health process
Reason, it is stand-by to obtain flax roving；
Step 2: the flax roving in step 1 successively to be carried out to pickling, kiering, oxygen bleaching and the processing of desizing process, obtain pre-
The flax roving of processing is stand-by；
Step 3: flax roving pretreated in step 2 is carried out spun yarn and winding procedure, it is stand-by to obtain dry numb cheese；
Step 4: dry hemp is made by warping denting, quilling, woven fabric and perching process in the dry numb cheese in step 3
Object.
