Description
Technical field
The present invention relates to a kind of quantitative test detection method of textile fiber content, relate in particular to the detection method of a kind of viloft of containing fiber and acrylic fibers or spandex blending product fiber content.
Background technology
Viloft fiber, translated name Wei Lefute fiber or vilofty fiber, it is another regenerated celulose fibre that Acordis company of Britain produces after Tencel fiber, it is by manually extracting raw material from special through the high-quality timber of biological breeding, produce gained with solvent method, belong to pure natural, high-grade environmental protection, pollution-free, biodegradable fiber.Can be to environment in viloft fiber production process, auxiliary material, auxiliary agent that production run is used are all nontoxic, and most of auxiliary agent and semi-manufacture fiber all recyclable, be a kind of novel environmental protection fiber.Because viloft fiber source is in natural material, there are some premium properties of native cellulose fibre, in addition unique fiber surface structural form, make fabric lining there is splendid permeability and moisture absorbing and sweat releasing performance, the garment material of its weaving is soft, wear slim and graceful, warmingly, washing is arranged conveniently, is subject to very much the welcome of consumption market.
Polyacrylonitrile fibre (polyacrylonitrile fiber), typically refers to more than 85% acrylonitrile copolymer or homopolymer fibre containing polyacrylonitrile, and China is called acrylic fibers.The copolymer fibre of acrylonitrile content between 35%～85%, is called modified acrylic fibre or modified acrylic fibers.Acrylic fibers are since realizing suitability for industrialized production, because its function admirable, raw material abundance develop very fast.This fiber softening, warmth retention property are good, and density ratio wool is little, can be widely used in replacing wool to make varicosity yarn, acrylic fibre blanket, acrylic fibers carpet, therefore there is the title of " synthetic wool ", " man-made hair ".
Sun-resistant and the weather-resistant property of acrylic fiber ranks first in all natural fibers and man-made fiber, and its resistance to damaging by worms property is better than wool, but the hydroscopicity of acrylic fibers is poor, and not easy dyeing makes the wearability of pure acrylic fibers goods be subject to certain limitation.
Spandex, China's polyurethane elastomeric fiber (polyurethane elastic fiber, PU) trade name, is the fiber that a kind of segmented copolymer taking polycarbamate as principal ingredient is made, famous " Lycra (Lycra) " that have the U.S. in external trade name.Polyurethane elastomeric fiber is that polyester or polyethers are divided into polyester-type and polyether-type according to soft chain segment part in chain structure, polyester or polyethers react with aromatic diisocyanate, generate the prepolymer of isocyanate end, then this prepolymer reacts and obtains segmented copolymer with the bifunctional compound that contains reactive hydrogen atom of chain extender one low relative molecular mass again, and synthetic segmented copolymer can become spandex by dry-spinning, wet spinning or melt-spinning.
Spandex not only has the such elasticity of rubber thread, also has the characteristic of general fiber, is therefore subject to people's favor as a kind of fabric fiber, and it can make various underwears, swimsuit, elastic cord, waistband etc., also can make stocking blank and bandage.
Single textile is in possessing certain superiority, often also there are a lot of defects, such as shortcomings such as acrylic fiber moisture absorption are poor, dyeing is difficult, these defective effects the development of single textile, and blending product is favored by consumer more and more because it has the advantage of two or more fibers concurrently, so-called blending product refers to the bi-component or the multicomponent fibre textile that are processed by mixed fibre, blending, interweave etc. by two or more fibrous materials.It can overcome the weakness of Single Fiber material self, fully gathers the advantage of multiple fiber, has greatly improved the functional of textile.
In quality inspection field, quantitative test for blending product adopts chemical dissolution method conventionally, so-called chemical dissolution method is exactly a component will selecting in certain agent dissolves blending product, then calculate the content of other component, but chemical dissolution method also has many weak points, such as, solubilising reagent and temperature of reaction all directly have influence on the accuracy of measurement result and the efficiency of surveying work, the chemical dissolution method that quality inspection unit adopts now needs 1～2.5 hour conventionally, and detection efficiency is low.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method of simple and efficient detection viloft fiber and acrylic fibers or spandex blending product.
In order to solve the problems of the technologies described above, the present invention adopts following technical characterictic:
A kind of viloft fiber and acrylic fibers or spandex blending product fiber content quantitative detecting method, comprise the following steps:
S1. viloft fiber and acrylic fibers or spandex blending product are placed in to take out rapidly after the constant temperature oven of 102～108 DEG C is dried and are placed in exsiccator and are cooled to room temperature, take the quality m of blending product
0;
S2., according to blending product (g): blending product is placed in DMF or DMA by the bath raio of reagent (mL)=1:100～200, under 90～100 DEG C of solution temperatures, shake 5～30 minutes continuously;
S3. by step S2) in be insoluble to N, the fiber water of dinethylformamide or DMA reagent cleans to neutral, and the constant temperature oven that is then placed in 102～108 DEG C is dried, taking-up is placed in exsiccator and is cooled to room temperature rapidly, takes the residual mass m of blending product
1.
The solubilising reagent that the method is selected and solution temperature can accelerate dissolution fiber under the condition of continuously concussion dissolving, greatly reduced detection time, improved detection efficiency.
As preferred version, step S2) described solution temperature is 95 DEG C, dissolution time is 10～15 minutes.This preferred version is the dissolving of accelerate dissolution fiber by a larger margin, has reduced to a greater degree detection time.
Further, described in step S2, the bath raio of blending product and reagent can be preferably 1:150 or 1:180, in the time that the amount of solubilising reagent is too small, dissolving fiber in blending product can not get abundant dissolving, make testing result out of true, in the time that the consumption of solubilising reagent is too much, although can make blending product fully dissolve, but can cause undoubtedly the waste of reagent, increase testing cost, in the time that the bath raio of control blending product and reagent is 1:150 or 1:180, can either make blending product fully dissolve, can save again the consumption of solubilising reagent.
The present invention is on the basis of further investigation, select N, dinethylformamide or N, N-dimethyl acetamide is as solubilising reagent, and solution temperature is controlled between 90～100 DEG C, because viloft fibre damage under this humid test condition is minimum, acrylic fibers or spandex all can dissolve completely, make final testing result and actual numerical value can keep highly consistent, there is very high accuracy.In addition, solubilising reagent of the present invention and solution temperature can accelerate acrylic fibers under the test condition that does not stop concussion or spandex dissolves, and has greatly reduced detection time, makes only need 5 minutes the shortest detection time under this temperature conditions, has improved detection efficiency.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further details.
