Description

A kind of content of silk gum is high, the continuous preparation method of silkworm long filament that can wash again
Technical field
The present invention relates to a kind of preparation method of silkworm long filament silk floss, is that a kind of content of silk gum is high specifically, can wash again the preparation method of silkworm long filament silk floss.
Background technology
Silk circle insider all know: the natural antibacterial of silk, mildew-resistant, Anti-moth-eating function are mainly to be brought into play by the silk gum self character of silk, as the T-shirt that summer, dress contained silk, its collar can be not smelly in the situation that making soaked with sweat, and main cause is exactly that silkworm silk gum has played antibacterial, antibacterial action.If the silk gum of silk product entirely comes out or is destroyed, just lost this function, also just no longer antibacterial, mildew-resistant, Anti-moth-eating.Also there is on the market at present different types of cocoon silk quilt of washing, but all more or less have some defects, affected the promotion and application that can wash cocoon silk quilt.At present, in the refining process that goes silk gum and degrease technique of silkworm long filament silk floss, mostly adopt alkaline medium and high temperature to realize the concise of silk silk floss and come unstuck and degrease both at home and abroad, gained silkworm long filament silk floss has following three kinds of results:
The first is not too white at silk cocoon intrinsic colour, utilizes special purpose machinery to select the yellow spotted cocoon or the dupion quick filature slabbing under 65 ℃ of left and right, caustic soda water infiltration condition that get off to make embryo silk floss reeling mill, because base silk floss is more black, need to use hydrogen peroxide bleaching.And bleaching must will utilize high temperature, high base number first the silk gum on silk to be removed to below 3%, then carry out high-load hydrogen peroxide bleaching, make like this silk silk floss very white, departed from the natural color of silk, very popular on the market.The silk floss just making has like this greatly reduced the utilization rate of silk cocoon not to be said, also in follow-up cocoon silk quilt is used, easily produces static and is easily stained with dirt, thereby lose the due antistatic feature of mulberry silk.Also because of silk gum recoverable amount very little, the continuous moisture retention variation of silk, for skin care, repairs the function of keratoderma and has a greatly reduced quality, and has lost the health cares such as the due natural skin care of mulberry silk.The functions such as this silk silk floss can be washed after processing by softener, but after washing several times, content of silk gum can be still less more, antibacterial, the mildew-resistant that silk is natural will exhaust, the compression resilience variation that silk itself is excellent, and warmth retention property declines;
The second is namely pure dupion or the bonscocoons of use in the situation that silk cocoon intrinsic colour is whiter, become the continuous stage of base with the quick filature of special purpose machinery, with the first, be the same, just in practicing process processed, reduced the consumption of hydrogen peroxide, reduced the experienced time processed, the continuous content of silk gum of silk making is higher, general content of silk gum can remain on 5% left and right, this silk is continuous continuous with the softener with hydrophobic grouping (for example with there being agent silicon class emulsion) processing silk, allow the appearance of silk fiber be coated one deck oil film shape material, such silk is continuous soft, touch up comfortable, silk floss is difficult for getting wet, so just can wash.Shortcoming is: because the reason of oil film, silk hygroscopicity is poor, and moisture retention is bad, and maintaining skin is had a greatly reduced quality.Also, because of too soft, compression resilience is poor, is exactly that warmth retention property is bad, can only make thin quilt;
The third is also in the situation that silk cocoon intrinsic colour is whiter, and institute base is continuous or cry the continuous string bag of craft without hydrogen peroxide bleaching, the preparation method of Here it is existing manual silk silk floss.This silk floss has retained the most natural characteristic of silk, and as careful use, level of comfort can be fine.Yet manual silk silk floss also has a fatal shortcoming, do not allow when drawing cocoon silk quilt silk tire exactly silk fiber disconnect as far as possible, in silk floss processed, retained silk silk gum (yes tries out for generations as far as possible, can not be unable to say for certain), content of silk gum is in 10% left and right, such high-load silk gum, again not through any other PROCESS FOR TREATMENT, silk gum is very easily soluble in water, once silk gum contacts with sweat and do not dry in time or the reason such as make moist, will make that silk gum is water-soluble to be become sticky colloid substance and cause and harden or local caking;
In above three kinds of results, first two can make can wash silk silk floss, by existing standard, can incorporate Grade A into, is mainly that softener has been added, and compression rebound rate is difficult to reach excellent grading index; But shortcoming is that contained silk gum amount is low, only has 3-5%, has affected quality and the service life of product.The third is to belong to the silk silk floss that can not wash, by present cocoon silk quilt standard, but can be classified as high-class product, and compression resilience is best, and maximum shortcoming is to wash.But in reality, with the higher cocoon silk quilt of this content of silk gum, grown having a good chance of hardening service time, because be in use difficult to avoid quilt not make moist or part is not soaked by sweat, also can run into picture child wets the bed, large ill or the special circumstances such as vomiting, the elderly's gatism of being drunk.If it is pretty troublesome that silkworm long filament is renovated, turned over and also become staple fibre, uncertainly can find producer to renovate to you, thereby affect the extensive use of cocoon silk quilt purposes.Silk industry is thought: the best silkworm long filament silk floss of washing must reach this standard: content of silk gum, between 5-15%, evenly and is stably solidificated on mulberry silk fiber; Under 30 ℃ of water temperatures, neutral detergent condition, with after cylinder class washing of drum type washing machine 20 times, content of silk gum will retain more than 60% on former basis, the compression rebound rate of silk seldom or constant, it is little that hygroscopicity hydrofuge follows the indexs such as pure natural mulberry silk is approaching, antibacterial, mildew-resistant and outward appearance etc. to change.
Summary of the invention
For overcoming the above-mentioned defect of going silk gum and degrease technique of existing silkworm long filament silk floss, the invention provides a kind of content of silk gum high, the continuous preparation method of silkworm long filament that can wash again, gained silkworm long filament silk floss is unlikely to silk gum and runs off in a large number and harden in follow-up processing and later water-washing process, and content of silk gum is high, and silk fiber intensity is high, compression rebound rate is high, antibacterial, mildew-resistant, Anti-moth-eating, long service life, has advantages of that pure natural mulberry silk is all.
For solving its technical problem, the technical solution used in the present invention is: first under 100 ℃ of high temperature, sour environment, in the softening mulberry silk base silk floss that comes unstuck, with the little molecule of acidity, protect glue and just practice the free group of the temporary transient grafting part of agent silk gum, allow the decreased solubility of silk gum, when content of silk gum reaches 15%, silk gum viscosity between silk fiber declines, coherent silk fiber is dissociated smoothly, so just on silk, retain in the silk gum of high-load and the flexibility of maintenance mulberry silk simultaneously and average out; Again with the sodium carbonate liquor that dilute by the experienced liquid in experienced barrel ph value is adjusted to neutrality, do not stop therebetween to stir, the acid solution that makes to practice in liquid and continuous sheet fully reacts with sodium carbonate, utilizes the expansive force of Bubble formation that grease unnecessary in continuous sheet is entered to experienced liquid from extruding the while between silk fiber by surfactant A ES emulsification, is removed subsequently in cleaning; Then will contain 15% silk gum, carry out concise except the solid glue scouring agent of silk floss utilization of degrease, after a large amount of silk gum is solidificated on mulberry silk fiber by graft reaction, then it is continuous through soft treatment, oven dry, to make a kind of content of silk gum silkworm long filament high, that can wash again; Concrete production method comprises the steps: the continuous preparation of 1. bases; 2. protecting glue just practices; 3. foaming oil removing; 4. solid glue is practiced again; 5. soft treatment; 6. removal of impurities is dried continuous.
Compared with prior art, because the present invention first makes fast mulberry silk base silk floss under alkaline environment, under sour environment, realize again and coming unstuck and part silk gum temporarily solidifies, then under neutral environment, remove grease, then under sour environment, remaining silk gum is completely curing; Therefore advantage of the present invention is: mulberry silk is unlikely to silk gum and runs off in a large number and harden in follow-up processing and later water-washing process, and content of silk gum is high, and silk fiber intensity is high, compression rebound rate is high, antibacterial, mildew-resistant, Anti-moth-eating, long service life, has all features of pure natural mulberry silk.
