Description

A kind of special health preserving adjuvant for jute fiber
Technical field
The present invention relates to the textile auxiliary agent technical field, particularly a kind of health special assistant of flax fibre.
Background technology
Raising along with the human substance life horizontal, originally people more from having transferred in the requirement to its comfortableness the concern of dress ornament durability, because flax fibre has sucting wet air permeability, low static behaviour and good antibacterial characteristics preferably, crudefiber crop fabric clothing lining more and more is subjected to people's favor.The lining of existing crudefiber crop fabric clothing is meant that mainly flax, ramie raw materials or this type of raw material and other fiber carry out blending/interweave as cotton, wool, chemical fibre, silk etc. and make, but, make that the crudefiber crop textiles does not have to be more widely used because flax, ramie price are higher.And jute is the second-biggest-in-the-world cellulose fibre that is only second to cotton, and it is cheap, and compares with flax, ramie and to have the moist and drapability of better loosing, comfortable and easy to wear, be difficult for sticking body summer, and antibacterial ability is only second to hemp, has huge using value and potentiality to be exploited.But because the content of lignin higher (can reach 10-13%) in the jute, than high several times of flax, fiber is very thick, hard, and spinnability is very poor, and this has restricted the application of jute aspect garment material greatly.In the prior art,, at first must come unstuck and the refinement fiber to above-mentioned natural fabric in order to improve the spinnability of above-mentioned material, even if but having carried out coming unstuck and refinement, its flax fibre that obtains still is in inclined to one side hard state, is difficult to weave.So must to through come unstuck and refinement after flax fibre carry out the improvement and the upgrading of fiber trait.
At present, commonly used flax fibre is carried out the method that proterties improves be to use the flax fibre health preserving adjuvant that it is carried out health, described fiber health is meant behind treatment process such as fiber is come unstuck, before spinning, makes used additives carry out the improvement of performances such as flexibility, spinnability to fiber; Described health preserving adjuvant can optionally comprise soft treatment auxiliary agent (bast softening agent), emulsifying agent, bleeding agent or humectant etc. according to the needs of the set performance of required product.Show that after deliberation in above-mentioned health preserving adjuvant, the proportioning of the selection of each difference in functionality auxiliary agent and each component on selected adjuvant component basis thereof is different to the function of performance improvements such as flax fibre spinnability, humidity.So in textile technology now, auxiliary agent and appropriate its component ratio of selecting of selecting to be applicable to different flax fibres and having good health performance, this is crucial technological parameter for flax spinning industry.
For tossa, in its health preserving adjuvant commonly used, often use amido silicon oil as the softener in the health preserving adjuvant.Pliability and slippery that amido silicon oil is given fiber are brought by amino; In amido silicon oil, its amino content can be represented by ammonia, in referring to and the milliliter number of the required 1 centinormal 1 hydrochloric acid of 1g amido silicon oil.In general, amino content is high more, and the ammonia value is just high more, and the fabric after the arrangement is just more soft, level and smooth so.To those skilled in the art, generally in order to improve the flexibility of fabric, most meetings select to improve the ammonia values of amido silicon oil, thereby its ammonia value is not less than 0.2 usually.But the too high meeting of ammonia value makes that fabric fibre smoothness (also can be described as slippery) is too high, and the cohesive force between fiber and the fiber is very little, the spinnability variation, and the ammonia value is not higher than 0.6 again usually in the prior art for this reason.In addition, along with the raising of the ammonia value of amido silicon oil, the oxidation probability of the active hydrogen in the amino increases, and is easy to oxidized and forms chromophore, causes the fabric fibre yellowing.For such problem, prior art is to adopt the technology of following bleaching to solve.Yet the bleaching process process has not only improved cost, and must bring certain sewage.
In addition, in spinning process, also should consider the humidity of fiber, suitable humidity (regain) is an important guarantee for the spinnability that improves fiber.Consider the problems referred to above, in the fiber health preserving adjuvant, add certain moisture agent or humectant usually separately, utilize the moisture pick-up properties of hygroscopic agent and the performance of keeping humidity of humectant, thereby guarantee the regain of fiber in spinning process.If but use single hygroscopic agent the moisture that is absorbed into the fiber inner core can not to be pinned, and because tossa is with respect to other fibers, it looses moist extremely strong, and the moisture that absorbs in the tossa is very easily lost, thereby can not effectively keep the humidity of fiber; Certainly, use single humectant can not in weaving process, in time absorb extraneous moisture, thus the intrastitial moisture of supplying in spinning process to be lost.
Summary of the invention
Technical problem to be solved by this invention is that the low excessively easy yellowing of too high then fiber of the lower ammonia value of fiber flexibility and the fiber smoothness of causing of the ammonia value of amido silicon oil in the prior art is too high, and so cohesive force decline between fiber is the relatively poor problem of spinnability; And then, overcome above-mentioned technical problem, and provide a kind of and can make tossa have good flexibility, have the very high special health preserving adjuvant for jute fiber of suitable fibre whiteness, spinnability by selecting the amido silicon oil of suitable ammonia value.
For solving the problems of the technologies described above, special health preserving adjuvant for jute fiber provided by the invention comprises 0.5~3 part of emulsifying agent, comprises that also the ammonia value is that 0.3~0.4 molecular weight is 4~8 parts of 300~30000 amido silicon oils.Described auxiliary agent preferably adds 0.5~4 part of 0.5~3 part of humectant and hygroscopic agent.
Wherein, described emulsifying agent is 1~2 part, and described amido silicon oil is 6 parts.Described humectant is 0.8~2 part.Hygroscopic agent is 1~3 part.Described auxiliary agent also comprises 5~7 parts of quaternary softeners.The ammonia value of described amido silicon oil is 0.35.The portion rate of described humectant and hygroscopic agent is 2/3~4/5.Described emulsifying agent is a nonionic emulsifier.Described humectant is preferably glycerine, described hygroscopic agent is preferably urea.
The present invention has advantage as described below:
(1) the present invention selects the ammonia value at 0.3~0.4 amido silicon oil, and the ratio of control adjuvant component umber, because the amido silicon oil of small-molecular weight can enter fibrous inside effectively, thereby improved the flexibility of tossa effectively, and guaranteed that the tossa surface has suitable smoothness, thereby being enough to make have between the tossa to form the necessary cohesive force of yarn, thereby has improved the spinnability of fiber; On the other hand, the selection of above-mentioned auxiliary agent and component umber thereof makes this health preserving adjuvant can offer an amount of amido silicon oil that fiber reaches required flexibility, can not increase owing to the excessive oxidation probability of auxiliary agent that makes of amido silicon oil, thereby obviously reduced the yellowing of tossa, guaranteed the suitable fibre whiteness of tossa.
(2) hygroscopic agent and humectant have been added simultaneously in the health preserving adjuvant of the present invention, wherein said humectant is pinned the moisture of fibrous inside effectively, but in weaving process, might cause scattering and disappearing of fibrous inside moisture, the hygroscopic agent in the auxiliary agent then can in time absorb moisture with the moisture that scatters and disappears once more by the external world and replenished fibrous inside this moment so, and by controlling the umber ratio of hygroscopic agent and humectant, thereby the wetting balance that the assurance fiber is inside and outside, the regain of required fiber in the maintenance tossa weaving process.
