DE2647423A1 - Flame effect yarn - is a semi-worsted made from mixture of long staple carrier sliver and short staple carded roving - Google Patents

Abstract

The mfg. process for an effect yarn uses a semi-worsted yarn formed from a long stapel carrier with short staple carded yarn of different colours, spun together to give a shimmering effect. The shot fibre sliver produced from the woollen card is mixed in the required proportion with the long staple slivers. This is fed into the section where the needle zone draws and tear the short fibre sliver so that the flame colours are distributed at random in the semi-worsted sliver passed to the spinning machine. Used for producing effect yarns for carpetings. The process delivers a flame effect yarn which gives the required colouring effects without incurring additional mfg. time or machine costs.

Description

Process for the production of an effect yarn

The invention relates to a novel semi-worsted yarn, as it is particularly for the production of 'geppich carpets' is intended for such material as well To give a lively impression in large areas is given to the basic thread Uniform color Additions of different color, which are scattered in a flame-like manner Distribution together with the half worsted carrier thread then a flamed effect thread form.

Such ground yarns with different colored flames can be obtained by different ones Manufacture technical processes: either by printing filaments or spun threads Yarns, or by brushing dyed material over flame yarn apparatus in the carded yarn spinning mill.

But since both procedures were quite cumbersome, they were also special machine effort required and even a little varied product supplied, the invention has set itself the task, the production of such To design and simplify flaming yarn so that it can be produced with the help of the in.

machines available in every carpet yarn mill without additional time and machine effort can be made and with regard to the varied appearance of the fancy yarn also meet high demands.

This object is achieved in a method for producing an effect yarn Made from a semi-worsted yarn, whose long-staple carrier thread with short-fiber carded yarn different color spun into the entire thread in a flame-like scattered distribution is solved according to the invention in that in a kind of combination of carded yarn and half-worsted yarn spinning the short fiber sliver produced on a carded yarn card in the required ratio together with the long staple belts in the Stretch is introduced, the needle field of which tears the short fiber tape during the stretching process and the flame ends produced in this way in an irregular distribution to that of the spinning machine to be fed semi-worsted yarn tape, so combed into the warped stretching tape.

The process saves numerous measures and machine expenses, those previously used in the manufacture of the sliver yarn were required and is achieved by the processes of tearing the short-fiber fibers taking place in the draw frame Components of their irregular distribution along the long staple belts. That in the Flame yarn produced in the manner described is expediently still twisted, that is to say two single threads are always twisted together. The product (thread or thread) When processed into eppich carpeting, this results in the popular mottled apples Appearance.

Based on the drawing of a so-called "route" is an exemplary embodiment of the invention described: The material presented in loose bands of the route likes a fiber ratio between the long staple ribbons and that on a carded yarn card produced roving intended to form the flame of about 5: 1. That Flame yarn should be made from strips of the base material of different widths 1 (delicately dashed) and a thin band of perhaps 1 g / m of roving 2 (coarse dashed), which are withdrawn from the containers 1 and 2 that have been set up. the three lanes of normal long staple tape (half worsted yarn). run together with. the Short fiber tape, which is made on the carded yarn card, over a Needle field N in the track head S.

There the merged strips are stretched considerably, e.g. six times its length, and in the process the thread of the flame is torn so that its short fibers in flaky Distribution as struck Single flakes appear in the drawn ribbon. This tape is then made on the spinning machine further distorted and, for example, to 15 to 30 times its entry length stretched. in the spun and preferably twisted effect yarn formed in this way the coated flakes appear due to the high stretching that has been carried out then as elongated flames.

Claims (3)

Claims: 1. A method for producing an effect yarn from a half-worsted yarn, whose long-staple carrier tape with short-fiber carded yarn (Roving) of a different color in a flame-like scattered distribution to the overall thread is spun, characterized in that the generated on a carded yarn card Short fiber tape together with the long staple tapes in the required ratio is introduced into the draw frame, the needle field of which the short fiber band is inserted during the drawing process tears and the so generated flame ends in an irregular distribution that of the pinning machine to be fed semi-worsted yarn tape. 2. The method according to claim 1, characterized in that for production stronger or weaker flames the fiber ratios and lengths, respectively Weights and feed quantities differ between sliver and carded yarn roving the different drafts required in each case on the draw frame and the spinning machine can be set. 3. The method according to claim 1 or 2, characterized in that the Long-staple carrier tape made of acrylic yarn and the added carded yarn roving as well made of acrylic fiber or nylon, cotton or wool.
