Abstract
This invention discloses one kind of lyocell - spun silk compound silk and its the manufacture method. This kind of lyocell - spun silk compound silk is make up of the core layer and the wrap round layer which enwind the core layer ; So called the core layer is lyocell silk or lyocell silk-spun silk synthetic fabric, the wrap round layer is spun silk; The lyocell- spun silk compound silk mentioned above can be manufactured by general air-jet spinning with two spray nozzles, the first spray nozzle and the second spray nozzle's pressure relations type is: N2=aN1+bkgf, a=0.5, b=0.35. This invention lyocell - spun silk compound silk, both can manifest the spun silk's fine crude protein textile fiber performance, and can maintain lyocell's eximious characteristic, uses this compound silk manufacture the lining, has spun silk textile's comfortableness, the polyester fiber's intensity, the gummy textile fiber's pendency performance, the silk's feel as well as the radiance, brightness and the bone feeling, are one kind of performance outstanding compound silk.
Description
Technical field
The present invention relates to a kind of compound silk and preparation method thereof, relate in particular to a kind of day silk-spun silk compound silk, and the preparation method who adopts Air-Jet Spinning.
Background technology
It silk (Tencel) fiber is a kind of free of contamination artificial natural fabric (refined fiber cellulose fiber).Because this fiber has drapability and the feel as the silk and the brightness and the vividness of cotton comfortableness, the intensity of polyester fiber, gluing fiber, therefore obtained the general favor of people, but be that the raw materials for production fabric of making that spins routinely more easily fluffs with the sky silk.Spun silk is a kind of protein fibre, and excellent feel and the comfortableness of taking are arranged, and still because of the relation of its length and fiber number, can't adopt pure cotton type equipment to process all the time.Therefore, many scientific and technical personnel adopt the method for blending that above-mentioned two kinds of fibers are carried out blending, as applicant's disclosed technology in Chinese patent application numbers 200310109049.2, though obtained certain effect, but because prepared blending product, two kinds of fiber hybrids together, can not embody advantage separately fully, therefore await further to improve.
Summary of the invention
One of technical issues that need to address of the present invention are to disclose a kind of day silk-spun silk compound silk, to overcome the above-mentioned defective that prior art exists, satisfy people's needs.
Another technical problem that the present invention need solve provides the preparation method of above-mentioned compound silk, so that it can realize suitability for industrialized production.
Silk-spun silk compound silk was made of the sandwich layer looping layer outer with being wrapped in sandwich layer in of the present invention day, and its fiber number is 120D～150D;
Said sandwich layer is day silk or day silk and the blended fiber of spun silk, and the fiber number of spun silk is 0.8～1.1dtex; The fiber number of it silk is 1.2～1.4dtex; In the sandwich layer, the weight percent content of preferred day silk is 60%～80%;
Said looping layer is a spun silk;
The weight ratio of looping layer and sandwich layer is: the looping layer: sandwich layer=1: 1.5～4.
Above-mentioned sky silk-spun silk compound silk can adopt general Air-Jet Spinning equipment to spin, and is the jet frame of MJS NO.802HR as Japanese village field company model, and this jet frame has former and later two nozzles, is used to form looping layer and sandwich layer.
The inventor thinks, as long as select suitable sky silk and the good continuous bar quality that forms spun silk, and adopt suitable spinning conditions, promptly can on above-mentioned equipment, make said day silk-spun silk compound silk, for this reason, the inventor has proposed following technical scheme through a large amount of tests, comprises the steps:
(1) pre-treatment of raw material:
Mix the c bar with what sky silk and spun silk were made pure day silk a bar and spun silk b bar and day silk/spun silk respectively, in mixing in doubling step, be spun into and have outer spun silk and internal layer sky silk/spun silk structure semi-products by the ordering of b, c, a, a, b;
(2) spinning:
Semi-products after then step (1) being handled spin by first nozzle and second nozzle that front and back are provided with in the Air-Jet Spinning equipment of two nozzles successively, and the pressure of first nozzle and second nozzle satisfies following relational expression:
N2=aN1+b Kgf, a=0.4～0.8, b=0.2～0.45, N1 is 0.25～0.4Kgf;
Preferred a=0.5, b=0.35, then N2 is 0.48～0.55Kgf, average is 0.51Kgf;
N2 is decided to be 0.51Kgf, N1 is 0.25～0.4Kgf, this is the result of inventor through a large amount of tests, this manufacturing condition has overcome the prejudice of this area, persons skilled in the art are all thought, these process conditions can't realize spinning on described MJS equipment, and the present invention carries out breakthrough change, thereby have obtained beyond thought effect.
According to the preferred scheme of the present invention, a day silk can adopt conventional method: blowing---comb and parallel cotton fibers prior to spinning---is pre-and become a bar, a bar quantitatively be/5 meters of 15～18 grams;
The continuous bar of thin,tough silk can adopt conventional method crush cutting to become the b bar, the b bar quantitatively be/5 meters of 8～10 grams;
The mixture of it silk-spun silk can adopt conventional method: blowing---comb and parallel cotton fibers prior to spinning---is pre-and become the c bar, quantitatively is/5 meters of 13～15 grams.
Temperature is 23～26 ℃ during spinning, and relative humidity is 75%～85%;
180～210 meters/minute of the linear velocities of the delivery roller of Air-Jet Spinning.
Under above-mentioned process conditions, because and the collocation mode of fashionable each component strip, make in the spun silk baseset in the semi-products of importing Air-Jet Spinning at skin, and internal layer is by sky silk and day silk, spun silk mixes, after these semi-products are fed Air-Jet Spinning equipment, when entering first nozzle, because of the big pressure of second nozzle its generation is circled round at the thinner and soft spun silk of skin, most of day silk of internal layer forms heart yarn because of the suction that is subjected to first nozzle, the spun silk that circles round is subjected to the pressure reversal of second nozzle to wrap in the outside of heart yarn, promptly obtains said day silk-spun silk compound silk of the present invention.
By above-mentioned disclosed technical scheme as seen, of the present invention day silk-spun silk compound silk, can on general MJS equipment, produce, sky silk-spun silk the compound silk that is obtained can embody the good natural protein fibre performance of spun silk, can keep simultaneously day excellent specific property of silk again, the lining that adopts this compound silk to make, drapability and feel as the silk and brightness with the comfortableness of manufactured silk fabric, the intensity of polyester fiber, gluing fiber, vividness and bony are a kind of compound silk of excellent performance.
