Abstract

The utility model relates to a various multiple composite bulked yarn with filament loop. A sandwich layer (3) is composed of heterochromatic composite yarns. A cortex (1) is composed of the single fiber (2) of a plurality of roots of wire loops and a pentalobal cross-section in wire arc-shaped, which forms the composite deformation dacron filament yarn. The composite yarn is composed of three single fibers of pentagon, hexagon and circular cross section. The utility model has the advantages of tight inner and loose external, soft inner and hard external, softness and fluffiness.

Description

The how different MULTIPLE COMPOSITE textured yarn of band wire ring and silk arc

The utility model relates to a kind of how different MULTIPLE COMPOSITE textured yarn with wire ring and silk arc, the special wool-like fabrics such as producing various naval ports that adapts to.

At present, domestic chemical fiber filament or only adopt two XORs, three different combination process, perhaps only adopt a kind of or two kinds of deformation techniques, the filament yarn of being produced, can not satisfy perhaps that wool fabrics is weaved, the needs of dyeing and finishing processing method, perhaps made fabric can't obtain requirements such as the desired body bone of good wool fabrics, elasticity, plentiful, active, sliding glutinous and gloss.

The purpose of this utility model provides a kind of how different MULTIPLE COMPOSITE textured yarn with wire ring and silk arc, thereby solves the shortcoming that above-mentioned existing filament yarn can not production high-quality wool fabrics.

The purpose of this utility model is achieved in that the how different MULTIPLE COMPOSITE textured yarn of band wire ring and silk arc, form sandwich layer by how different compound silk, form cortex by the many single fibers that are the pentalobal cross-section of wire ring and silk arcuation, constitute composite deformation polyester filament yarn, described compound silk is made up of three kinds of single fibers of pentagon, hexagon and circular cross-section.The utility model covers core layer surface by the thinner thin fibre that is wire ring and silk arcuation of fiber number and forms cortex, has the woolly aspect of soft fluffy, and sandwich layer then is to be arranged by the thick fibre of multiple cross sectional shape more straightly, makes made fabric have the body bone.

The utlity model has following effect and advantage:

1, have tight inside but loose outsidely, interior firm outer soft structure becomes the fluffy structure that the body bone is arranged.

2, be able to take to weave the processing of dyeing and finishing technology because of the required twisting of production high-quality performance wool fabrics.

3, the wool fabrics with the utility model production has soft gloss, galloping light is arranged, and do not have aurora.

4, it is glutinous to have a good body bone, elasticity, abundant cunning with the wool fabrics of the utility model production, active feel and actual wearability.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a cross sectional representation of the present utility model

Fig. 2 is vertical schematic diagram of the present utility model

Referring to accompanying drawing, the utility model is formed sandwich layer 3 by how different compound silk, form cortex 1 by the many single fibers 2 that are the pentalobal cross-section of wire ring and silk arcuation, constitute composite deformation polyester filament yarn, described compound silk can be made up of three kinds of single fibers in pentagon, hexagon, octagon and the circular cross-section single fiber.Single fiber of the present utility model is to make two kinds of pre-oriented yarns (POY) by polyester slice after spinning, the filament number of these two kinds of silks, and cross sectional shapes etc. are different, and wherein a kind of pre-oriented yarn is the pentalobal cross-section, and filament number is thinner; Another kind of pre-oriented yarn is pentagon, hexagon, octagon and circular cross-section, this two classes pre-oriented yarn is passed through draw texture respectively after, its filament number, percent thermal shrinkage are with different.Compound silk selects pentagon, hexagon and circular three kinds of single fibers in the present embodiment, the so-called how different single fiber that contains two or more noncircular cross sections exactly in compound silk just forms how different compound silk with pentagon, hexagon and the circular three kinds of monofilament of selecting for use after drawing-off is compound.Cortex and sandwich layer are passed through composite deformation together with certain proportion again, and the thin fibre in the cortex will produce the fine and closely woven wire ring and the silk arc of differently curved degree, form different distribution length simultaneously, and the excursion of this distribution length is 5-25%.The line density of the leaf cross section of the utility model single fiber is the 1.0-2.5 dtex, its stretch modulus is 10-20 li of ox/dtex, the line density of three kinds of single fibers is respectively 1.0-2.5 dtex, 2.0-4.0 dtex in the described compound silk, and its stretch modulus is respectively 10-20 li of ox/dtex, 15-25 li of ox/dtex.The utility model can be separately by weaving, and the simulate wool naval port kind fabric of excellent performance is processed in dyeing and finishing.
