Summary of the invention
The object of this invention is to provide a kind of three axles that are suitable for the non-cashmere-coverage-rate such as Rendezvous Point such as grade of high cashmere coverage rate is composite spinning technique.
For achieving the above object, the technical solution used in the present invention is: three axles of non-cashmere-coverage-rate such as Rendezvous Point such as grade are composite spinning technique, it is characterized in that: adopt and on common ring spinning frame, increase active tension dish and two locators that are used for respectively controlling cashmere yarn (cashmere fiber yarn) and wool yarn (wool fibre yarn) position that are used for controlling endless tow tension force, implement cashmere yarn, wool yarn and endless tow with three axles system feedings and the compound mode of Rendezvous Point such as non-, form the composite yarn of high cashmere coverage rate.
Three axles of non-cashmere-coverage-rate such as Rendezvous Point such as grade are composite spinning technique, it is characterized in that concrete steps are:
1) preparation of ring spinning frame: increase an active tension dish that is used for controlling endless tow tension force on common ring spinning frame, increase by first locator 4 that is used for controlling cashmere yarn position, increase by second locator 5 that is used for controlling wool yarn position; Active tension dish 6 is arranged on the top of the upper front roller of front roller 7, and contacts with the roller compact of going forward of front roller and by the transmission of upper front roller friction-driven; Endless tow is around the upper front roller of this front roller, by the jaw of the moving feeding of upper front roller friction belt front roller;
2) get cashmere rove bar, wool slubbing bar is fed by the rear roller of ring spinning frame, after drawing-off, form and stretch parallel cashmere yarn 1 and wool yarn 2, respectively by the jaw of the first locator 4 and the second locator 5 location feeding front rollers 7; Endless tow 3 grips conveying through the friction of active tension dish 6, directly between cashmere yarn 1 and wool yarn 2, feeds the jaw of front roller 7, forms the feeding of three axles systems;
3) when described cashmere yarn 1, wool yarn 2 and endless tow 3 are exported from the jaw of front roller, in the non-compound mode of convergent point that waits, make wool yarn 2 first compound at the jaw place of front roller with endless tow 3, form in endless tow 3 is stretched in, wool yarn 2 is more loose be wound in outside; And then compound with the cashmere yarn 1 of jaw that goes out front roller, form cashmere and be more coated over yarn surface, and mutually tangle again the composite yarn 9 of the cashmere-coverage-rate of obvolvent with wool fibre.
The cashmere coverage rate that described cashmere-coverage-rate refers to described composite yarn 9 surfaces higher than, even far above the cashmere mass ratio of actual composite spinning.Described cashmere-coverage-rate is cashmere outsourcing coverage rate, reaches 40%-100%.
Described cashmere yarn 1 and the spacing 1-25mm between endless tow 3 (preferably 2-20mm), the spacing between wool yarn 2 and endless tow 3 is 1-20mm (preferably 1-15mm).
Described cashmere yarn 1 and wool yarn 2 are the natural tension force of spinning, drawing; The tension force of endless tow 3 is 1-50cN (preferably 4-30cN), and wherein the tension force of endless tow 3 will be higher than described natural tension force.Wherein, because the drafting tension of staple fibre yarn depends on the factors such as interfibrous cohesive force, draw ratio, yarn line density, draft speed, therefore be called nature tension force.Because the cohesive force of wool is large compared with cashmere, so when other factors are identical or close, the natural tension force of cashmere yarn 1 is less than the natural tension force of wool yarn 2 in theory.And the tension force of the relative endless tow 3 of natural tension force is little.
The mass ratio of cashmere yarn 1, wool yarn 2, endless tow 3 is 10-80: 10-80: 10-50, is preferably 30-60: 10-40: 10-30, the summation of mass ratio must be 100.
Described endless tow 3 refers to polyester filament, chinlon filament, silk long filament, polypropylene filament yarn, polyvinyl long filament or viscose filament yarn.
Three described axle systems refer to that cashmere yarn 1 is an axle, and with natural tension force feeding, looping is at outermost layer; Wool yarn 2 is an axle, and with natural tension force feeding, looping, in endless tow 3, is positioned at cashmere inner side, and mutually tangles with cashmere; Endless tow 3 is an axle, and to feed higher than natural tension force, itself becomes yarn core, and is positioned at the internal layer of composite yarn together with first compound wool yarn 2.
Because wool yarn 2 has slightly high natural tension force relatively, therefore can shift to an earlier date and form looping with endless tow 3 well; Cashmere yarn 1 have relatively lower slightly natural tension force can lag behind form loopings with AB section composite yarn 8, can effectively increase thus the obvolvent of cashmere to AB section composite yarn 8, avoid layering.The high-tension of described endless tow 3 refers to by active tension dish 6 trench diameter and is less than active tension dish 6 cylindrical contact diameters, and the formed linear velocity of sending endless tow 3 is less than the linear velocity of front roller feeding and the high-tension that produces.This high-tension, will cause the spiral looping of 2 pairs of endless tows 3 of wool yarn and increase fluctuating and the surface area of AB section composite yarn 8, is conducive to the gripping to wool yarn 2.
Three axles such as non-cashmere-coverage-rate such as Rendezvous Point such as grade are the spacing that the certain intervals in composite spinning refers to cashmere yarn 1 and wool yarn 2 and endless tow 3.Described position refers to that endless tow 3 is central, and cashmere yarn 1 and wool yarn 2 are in endless tow 3 both sides.
Described non-ly wait that convergent point is compound refers to that at the first Rendezvous Point be compound by wool yarn 2 and endless tow 3, the second Rendezvous Point be by cashmere yarn 1 and the first Rendezvous Point after composite yarn section compound.
The rotation of described active tension dish 6 is by the contact friction with front roller, by front roller rotation, is driven.
The non-cashmere outer cladding ratio of Rendezvous Point that waits can be adjusted by one of three kinds of modes or combination: be 1. the composite quality ratio of adjusting cashmere yarn, wool yarn, endless tow three; 2. be that while adjusting front roller output, cashmere yarn, wool yarn and endless tow three's relative position, to increase outer cladding rate; 3. be the tension force of adjusting cashmere yarn, wool yarn, endless tow three, increase coverage rate and the triangular cohesive force of cashmere.And preferentially, to adjust 2. and 3., to adjust relative position and tension force, adjust the outer cladding rate of cashmere.
Three axles are that the cashmere yarn 1 in composite spinning also can change other rare hair fibers into, and as rabbit suede, yakwool, ermine suede, Arctic fox suede or superfine wool yarn, or wherein any proportioning of two kinds is mixed yarn.Wool yarn used is substantially constant, also uses rabbit hair yarn.Described endless tow 3 refers to terylene, polyamide fibre, silk, polypropylene fibre, polyvinyl or viscose filament yarn etc.
This technique not only can be used for the high coverage rate composite spinning of cashmere, can for high coverage rate three axles of the rare hair fibrids such as yakwool, rabbit suede, ermine suede, Arctic fox suede or superfine wool, be also composite spinning by replace cashmere yarn 1 with rare hair fibrid yarn, and as the yarn of using of grade textiles.
Beneficial effect of the present invention is: 1. only on common fine spining machine, increasing an active tension dish and two locators, just to have solved cashmere-coverage-rate three axles be composite spinning, and method is simple and direct, practical; 2. by adjusting relative position and the tension force of cashmere yarn, wool yarn and endless tow three axles, can effectively obtain the height ratio cashmere appearance style of low ratio cashmere content (10%-60%) and the cashmere composite yarn of feel (outer cladding rate reaches 40%-100%); This technique is suitable for high cashmere coverage rate, to obtain both composite strengthening and raising spinnability, keeps again the high-count cashmere composite yarn of cashmere style.3. can improve intensity, spinnability and the spinning row yielding of cashmere yarn, reduce yarn defect; 4. this composite spinning can be extrapolated to and treasure hair fibrid, if high coverage rate three axles of the rare hair fiber of yakwool, rabbit suede, ermine suede, Arctic fox suede, superfine wool etc. are composite spinning, and the acquisition of the high-grade textile product of the rare hair fiber of this class.
