MANUFACTURING METHOD FOR CARDED ?ber length, and of course, not suitable to process on cotton WOOLEN YARN spinning system because these are too long and it is too dif?cult to open the ?bers. The Woolen card is effective and BACKGROUND OF THE INVENTION convenient to process the dyed and blended ?bers. The [0001] 1. Field of the Invention splitted and delivered to make bundle is processed on mule . So this system is only tWo process to make [0002] The present invention relates to the ?eld of carded yarn from fed materials. It is very simple and cost effective. Woolen yam and in particular, manufacturing method for carded Woolen yarn. [0011] But the are too coarse, Weak and uneven. [0003] 2. DESCRIPTION OF THE BACKGROUND [0012] Generally yarns are doubled and tWisted to [0004] Woolen yarns are spun on Woolen spinning system make sWeaters to have good appearance and to prevent Which is composed of Woolen card and mule spinning distortion. But Woolen yarns are too coarse to make doubled machine. Dyed ?bers are fed to a Woolen card and bundle of yarn. And Woolen yarns are much Weak for Weaving. To slivers is produced by splitting card Web. Woolen yarn is make ?ner yarn on Woolen system, the siZe of sliver from the spun on mule spinning machine With these slivers. This Woolen card must be reduced according to the yarn count. So Woolen spinning system is simple and effective to spin ?bers if yarn number is ?ner by one-half, the production rate of of short length Which can not be spun on Worsted spinning sliver from the card is reduced by one-half As the sliver siZe system. But only coarser count of yarn can be spun on this is thinner and Weaker, the speed of doffer must be sloWer. So system. More over the yarn evenness is not good and the the combined effect of these tWo factors reduces the pro strength of yarn is inferior. Especially ?ner yarn spun on this duction rate much more than reduction rate of the yarn siZe. system require stiff cost increase because of sharp drop in The decrease of production rate of mule spinning is the same productivity. So, usually single yarn is applied to make as that of Woolen card by reduction of yarn siZe. Those sWeaters, resulting in distortion of garment. Finer yarn can reductions of production rate make the yarn cost rise sharply. be produced With the same dyed short ?bers by this inven Additionally, the ?ner must be selected to spin ?ner tion. This ?ner yarn can be plied With comparatively loW yarn and this adds the cost heavily to the already expensive cost. SWeaters made With this doubled and tWisted yarn has production cost. better appearance Without distortion of fabric. [0013] In this invention, the delivered Web is taken from the doffer of the last mountain to make ball top by means of SUMMARY OF THE INVENTION top making apparatus. The top making apparatus is attached [0005] Various ?bers of short length are dyed in loose ?ber to the Woolen card Which is the same apparatus as attached dyeing machine, dried, oiled and fed to conventional Wool to Worsted card. The top is fed on the draW frame of the card, in front of Which top making apparatus is attached to cotton spinning system. The ?ber length of the top is much receive the Web Which is ?oWing out from the doffer of ?nal longer than that of cotton. The distance betWeen rollers mountain. The Web is converted top of ball shape. This top according to the ?ber length is controlled With the technique is fed to the draW frame of cotton system. After four passage described in US. Pat. No. 5,638,580. Too long ?bers may be of draWing, the sliver are fed to the roving frame to make broken by means of adjusting the distance of rollers of roving. On spinning frame, Woolen yarn is spun With this draWing frames. To control ?bers Which are much longer . than cotton on the draW frame of the cotton system is important. Usually, four passage of draWing is applied to get [0006] Parallel of ?ber is improved by draWing. The yarn smooth distribution of ?ber length. The slivers produced has better evenness and better strength. Much ?ner yarn can from the draWing process are fed on roving frame. If the acquired With short ?bers Which are not suitable for Worsted longest ?ber length is less than 55 mm, the Weighting and spinning. top roller arrangement is regularly set. But if the longest ?ber is longer than 55 mm, middle top rollers are changed BRIEF DESCRIPTION OF DRAWINGS to the grooved roller shoWn as FIG. 3. The roving produced [0007] FIG. 1 shoWs process of conventional Woolen from the roving frame is processed on the ring frame to spinning make yam. If the longest ?ber length is longer than 55 mm, the grooved middle top rollers are applied. Drafting ratio is FIG. 2 shoWs process of spinning by the invention [0008] much less comparing conventional cotton spinning. TWist [0009] FIG. 3 shoWs recessed area of cut boss and state of per meter is higher than regular Woolen yarn by 10~15%. action of ?ber ?eece against apron. In this ?gure, the reference numerals are bottom roller1, non-cut area of top [0014] This eXtra tWist is untWisted by doubling and roller boss2, cut area of top roller boss3, straight apron4, tWisting. bent apron by ?ber ?eece Which is being passed betWeen [0015] Cotton system is inconvenient to process dyed bottom and top apron. ?bers like cotton, rayon and nylon lending With Wool because changing of small lot siZe is almost impossible on DETAILED DESCRIPTION OF THE bloWing and carding machine of cotton system. By this PREFERRED EMBODIMENT invention, the convenient and effective Woolen card is [0010] The primary objective is to spin ?ner yarn, that is, utiliZed to process almost any ?ber to get good quality of 1/30 or ?ner count With short ?bers like lamb’s Wool, cash Woolen yarn. Concerning the transferring of material from mere, carboniZed pieces Wool, etc, Whose usual yarn count Woolen card to the draWing frame, other methods can be is coarser than 1/15. These ?ber are not suitable to process on applied, for eXample, the delivering Web from the doffer of Worsted spinning system because of the shortness of the Woolen card can be condensed and coiled to a can.

EXAMPLE 1 The second passage of draWing Was processed With roller gauge of 55 mm. The third and last passage Was processed [0016] CarboniZed lamb’s WOOl(18/i)30%, carbonized With the same 55 mm gauge. On the roving frame, regular pieces WOOl(18/i)30%. (18p)40% Was mixed, dyed roller setting Was applied roller gauge of 55 mm. Regular and oiled by conventional method. The dyed ?ber Was fed to roller setting Was applied With on the frame the four mountain Woolen card equipped With top making apparatus, making ball top. With roller gauge 55 mm, speed 9,000 RPM, yarn count 1/36, and 590 T.P.M. And T.P.M of doubling and [0017] The top Was processed on draW frame of cotton tWisting Was 230. SWeater Was knitted by 16 gauge of ?at system. The distance betWeen ?rst and 3rd roller Was machine. The sWeater Was With good quality, ?ner adjusted as 110 mm at the passage of the draWing, and the teXture and handle of cashmere. gauge Was adjusted, third and last passage. On roving frame, the distance betWeen front and second roller Was set as 60 mm and the grooved top rollers Were applied. The grooved What is claimed is; top rollers Were applied on spinning frame to spin 1/30. The 1.
