Description

DETAILED DESCRIPTION OF THE INVENTION The present method is useful for processing fibrous flat structures consisting of yarns in the worsted yarn strength range and/or combed worsted yarns for clothing, furniture and automobile seat upholstery and decoration.

Methods are known in which coarse carrier fabrics and pre-reinforced fleeces can be densified by multiple needle pricking to form layered articles for industrial textiles and floor coverings.

It is known that the fabric for furniture upholstery according to Nishijmushi Patent Application Publication No. 2,522,871 can be provided with multiple nail penetrations, a large volume due to the seeds, a fluffing effect 7 and a high pressure strength.

The known methods are either to create a free-standing, flat construction OI needle laminate or to increase the volume of the woven fabric, but to create a fluffy profile.

The object of the present invention is to produce flat fibrous structures for clothing, furniture, moving wheels, decorations, etc., especially those consisting of yarns in the strength range of worsted silk yarns and/or combed worsted yarns.
The goal is to develop processing methods that can be adjusted "on demand" for various purposes.

By this processing method, it is possible to selectively influence the material composition, internal fiber/thread structure-1 coloring, surface structure, and effect-forming body later on in the process of constructing a flat object.

In addition, high productivity (compared to conventional processing methods such as sewing, felting, fluffing, embossing, etc.) as a result of optimum material use and reduction of the number of processes, or process substitution must be possible. No. The method should enable the use of yarns made according to a new high-productivity yarn-forming method for fashionable clothing and other applications.

The object of the present invention is to produce flat-structured textile fabrics for clothing, furniture and car seat upholstery and decoration, consisting of worsted light frequency range yarns and/or combed yarns, as a remarkable strip. In accordance with the law, by needle pricking, the selected unspun fiber materials and/or fiber compositions and flat compositions with different or unique shapes or flat materials for processing consisting of kento combinations are integrated. It is to let them pass.

Thereby, the fiber physical and garment physiological properties and/or modal effects should be modified or adapted to specific use characteristics and the normally required processing steps should be replaced or reduced.

The task is to process yarns of the worsted yarn type strength range and/or combed worsted yarns, such as rotor yarns, into fibrous flat structures or yarn aggregates of worsted yarns, hereinafter referred to as the strips to be processed, using suitable known equipment. The problem is solved by continuously withdrawing.

The strip to be processed is brought into contact with a processing flat, the latter preferably being continuously guided over its entire surface in the same direction and at a speed of 1" by known means.

Non-reinforced or pre-reinforced fiber material fleeces, aligned or unaligned to processing flats, such as wool, e.g. hard-to-spun or short-fiber wool or worsted fiber material mixtures; or combed worsted yarn, such as sedgerite spun material (ReiBspinnsto).
ff).

The work flat, consisting of a wreath of fibrous material 7, may contain untreated fibers, such as mohair or stichel, and may contain knots, tangles or tassels to create a color contrast. It may also be made of aligned or unaligned yarns.

The flat material for processing can be a fibrous flat structure of the same or different phase family composition and/or configuration or pattern as the strip to be processed, such as imitation fur, lining material. The area N of the flat object to be processed is at most the same as or lighter than the area weight of the strip to be processed in each case.

The processing of the flat material for processing can be carried out on the top side or on the bottom side of the strip to be processed, or on both sides, possibly even on multiple pages, in particular completely covering the top and/or bottom side.

A layered article is produced which is transferred without tension or with different tensions between the layers to the known multi-needle device of the known single-sided or double-needle felting machine.

The needle felting of the strips to be processed and of the workpieces or laminated products is carried out with continuous withdrawal using single or double needling devices of known needle felting machines. Use a felt needle, preferably a notch needle or a hook needle, to make needles with 5 needles per crll.
Punctures are performed in 0 to 1200 locations, with varying depths and frequencies, depending on the pattern.

By means of needle pricking, a transfer or insertion of fiber material components, such as natural fiber materials and/or effect fibers or fibers of the treated secondary raw material, takes place from the processing flat to the strip to be processed. The fibrous material portion is grasped by the movement of the setting needle and is followed in the puncturing direction.

Entering the notch, all the punctured layers or threads, i.e. the fiber parts from the processing flat and the strip to be processed, are entrained in the puncture direction, which can also be diametrical, so that the fiber ends or - the traps penetrate the layer and are distributed in the direction of the puncture, in parts largely beyond the surface.

The effects to be achieved can optionally be: a) Fibers from the processing flat of the strip to be processed, e.g. wool, enrichment with effect threads, color compositions, fibers; / Modification of the yarn structure and volume expansion as well as suppression strength and (improvements in the yarn device) possible reduction in color contrast or difference in length of fluff according to the pattern, without significant material loss and additional process steps. c) Combination of two different flat structures with the effects listed in a) and/or b); d) Shielding of defects in the strip to be processed; e) Reduction of processing. Yarn aggregate as a strip-like material and flat material for processing
In the proboscis, for example, in the 4 stitches, with a thread layer or a fleece or a fleece with a thread layer:
or the bonding of fiber/yarn systems into free-standing planar structures with good compressive strength with or without fluffing effects.

Fiber bonds can be broken as a result of the transposition of fibers from the processing plain material to the strip to be processed and vice versa. This results in short, uniform fuzz on the cut surface.

The present invention will be illustrated by the following examples: Example 1 Worsted yarn type yarn strength range yarn and/or combed worsted yarn.
The strip to be processed consisting of rotor (open end) yarn, MJS (Murayama jet) yarn, friction yarn or white spun yarn contains less than 50% wool. Conventional surface improvements (e.g. by fluffing) cannot be achieved without a reduction in the quality of the surface.
Difficulties arise due to girdle or sugar effects as a result of yarns or white spun yarns. Since these yarns have a round cross-section U and are stable and have little fluff, a fluffing process is often necessary, leading to high dye loss. For the fluff C process, it is always the outside fi111 of the yarn! Only fiber can be reached.

According to the invention, the wool of the processing flat is introduced into the improved strip made of this thread on the upper side or the lower side or on both the upper and lower sides, and then multiple needles are added from above or below or from above and below using a needle felting machine. Insert. When the head of a felting needle, preferably a CB needle, projects through the layered product, the fiber ends are transferred by means of the notch throughout the strip to be processed and from the processing flat to the top and/or bottom side.

Some parts protrude from the strip to be processed and form a fuzzy surface. The deeper the puncture, the longer the fluff becomes, and the more the number of punctures per d, the thicker it becomes.

Example ■ According to the present invention, a flat material for processing made of secondary raw material fleece is introduced into a typical flat structure for clothing as a belt-like material to be processed for special use in extremely cold regions, and the fabrication of the fabric is avoided, resulting in unfavorable effects on the front side. It is possible to combine without affecting the

In this case, the puncture depth of the CB notch needle exceeds the next curve of the strip to be processed.

Embodiment ■ According to the present invention, the characteristics of the well-known double-weave double weave, which has a strong pattern, for example, the back side of the base stripes, can be realized by changing the material composition,
This can be achieved by combining two flat structures with different compositions, patterns, and color configurations as a strip to be processed and a flat object for processing, and applying the needle pricking process from the back side. Reach the top or front side of something.

Starting from a worsted flat construction as the strip to be processed, the processing flat can likewise be a worsted woven fabric, but it can also be a synthetic flat construction with fur-like properties or lining properties. Depending on the purpose of use, a wreath of secondary raw fibers or a foam may optionally be placed between the two flat materials.

Example (2) Two sheets of the same worsted yarn flat composition are stacked as the strips to be processed according to the invention with their upper sides, i.e., faces Ill facing each other. On the outer surface, 7 wreaths of oriented fiber material consisting of wool or other preferably long-fiber fiber material with or without effect fiber material are introduced as working flats in each case. The needle pricking process on both sides results in the penetration of the fiber material from the processing flat through one of the strips to be processed into the second strip to be processed, and also the fiber material from the strip to be processed. It also participates in fiber dislocation in the direction of needle puncture. After the needling process, both strips are pulled apart by the action of a tensile force at an angle of 90' to the plane of the needle bed, and when cut at the fiber-reducing dislocation, short, uniform strips are formed on both surfaces of the processed strip. Fluff occurs, for example with contrasting colors or as a mixture.

One of the strips to be processed acts as a processing flat and similar cuttable fiber penetrations occur even in the absence of a fiber fleece.

Example V A worsted yarn yarn aggregate as a strip to be processed according to the invention and seven wreaths as a flat object for processing are combined, and on the latter there is an angle of 10' with respect to the longitudinal direction of the flat object for processing. ...
There are aligned or unaligned yarn layers within 170'. When 100 to 500 needle punctures are performed per d on strips and flat objects, thread dislocation occurs from one thread system to the other, especially in the puncture areas around thread intersections, resulting in coalescence and thread waste. A combination will occur.

This bonding and fiber dislocation from the additional fleece results in a rigid flat construction for the garment.

EXAMPLE ■ According to the invention, the back side of a strip to be processed consisting of a yarn that is difficult to blend with effect fibers or does not contain effect fibers is interspersed with effect fibers in the form of knots, tufts or bristles using known equipment.

The strip is then guided to the needle puncture device and punctured from the back side, so that the effect fibers are bonded into a flat structure and the majority of the fibers are formed in the direction of the needle puncture from the upper side, i.e. the front side, of the strip to be processed, depending on the puncture depth. It will be withdrawn to some extent. On the reverse side, depending on the puncture frequency, the remains of the canine or nodule, tangle or tassel remain visible, forming, for example, a color effect.
