Abstract

The invention belongs to the field of textile raw materials, and solves the problem of poor hand feeling caused by hardening after yarns are woven into cloth, and the specific scheme is as follows: the covering yarn is composed of a decorative yarn and a polyester fixed yarn spirally wound outside the decorative yarn, the polyester fixed yarn is subjected to setting process treatment, the decorative yarn is a hollow ribbon yarn, and false twisting treatment is performed while the decorative yarn and the polyester fixed yarn are wound. After the polyester solid yarns are treated by the shaping process, the polyester solid yarns are not easy to shrink, and the arrangement tightness of the decorative yarns in the axial direction of the polyester solid yarns is stable and fluffy; meanwhile, as the decorative yarn is a hollow tape yarn, the decorative yarn is uniform and fluffy, so that the whole covered yarn is fluffy; in addition, the scheme adopts the false twisting process to enable the whole covered yarn to have elasticity, and the selection of raw materials (polyester yarn fixing and decoration yarn) and the combination of the process enable the covered yarn to be fluffy and flat when being woven into cloth.

Description

Covered yarn

Technical Field

The invention relates to yarn processing, in particular to covered yarn.

Background

The production process of the covered yarn is also called wrapped yarn, and the covered yarn is a yarn with a novel structure, which takes filament or short fiber as a yarn core and is wrapped by another filament or short fiber yarn strip. The core yarn is wrapped by the outer wrapping yarn in a spiral manner. It features uniform yarn, bulkiness, smooth yarn, less filoplume, high strength and less broken ends.

The fixing yarn is also called winding yarn, and is covered outside the core yarn and the decorative yarn to fix the pattern and prevent displacement or deformation. After the existing finished product of the wrapping yarn is finished, the wrapping yarn is contracted due to yarn fixing, so that the arrangement of the decorative yarn is tight, the wrapping yarn is hard after being dyed, and the cloth cover effect and the hand feeling are poor after the cloth is woven.

Disclosure of Invention

The invention aims to provide a covering yarn, which is woven into fluffy cloth.

The technical purpose of the invention is realized by the following technical scheme: the covering yarn is composed of a decorative yarn and a polyester fixed yarn spirally wound outside the decorative yarn, the polyester fixed yarn is subjected to setting process treatment, the decorative yarn is a hollow ribbon yarn, and false twisting treatment is performed while the decorative yarn and the polyester fixed yarn are wound.

After the polyester solid yarns are treated by the shaping process, the polyester solid yarns are not easy to shrink, and the arrangement tightness of the decorative yarns in the axial direction of the polyester solid yarns is stable and fluffy; meanwhile, the decorative yarn is a hollow tape yarn, so that the decorative yarn is fluffy, and the whole covered yarn is fluffy; in addition, the scheme adopts the false twisting process to enable the whole covered yarn to have elasticity, and the selection of raw materials (polyester yarn fixing and decoration yarn) and the combination of the process enable the covered yarn to be fluffy when being woven into cloth.

Further, the hollow section of the decorative yarn is in a regular hexagon shape.

The regular hexagon has good stability, so that the decorative yarn is not easy to compress and collapse, and the fluffiness of the decorative yarn is kept.

Furthermore, the hollow tape yarns are of a hollow tubular structure woven in a flat-needle weft knitting mode, and each layer of the hollow tubular structure is composed of a plurality of loops.

Each layer of the hollow band yarn has a plurality of loops, which can be regarded as a hollow tubular structure with porous side walls, so that the bulkiness of the decoration yarn is further improved.

Further, the hollow tape yarns are soaked by hot melt adhesive and dried to form a hollow tubular structure.

The yarn friction easily produces static to make hollow tubular structure take place to collapse easily, the hot melt adhesive has insulating nature, thereby keeps the fluffy degree of ornamental yarn.

Furthermore, the mass ratio of the hot melt adhesive to the decorative yarn is 1: 10.

Too much hot melt adhesive leads to poor skin touch of the decorative yarn, too little hot melt adhesive easily leads to insufficient coating rate of the decorative yarn, and the quality ratio is controlled to be the ratio.

Further, hollow belt yarn carries out the drying through the desiccator, and the desiccator includes the platform, be located the conveyer belt of platform top, fix spacer on the conveyer belt, fix platform one side and ascending fan of wind direction slope, be located the deflector that the fan deviates from platform one side, and the wind-force radiation area of fan sets up an impact column near the edge of conveyer belt.

The conveying belt rotates to drive the separating sheet to rotate together, the hollow belt yarns on the platform are separated and conveyed, the hollow belt yarns are thrown out of the platform and collide and disperse with the impact column when falling to the edge of a wind power radiation area of the fan, then the hollow belt yarns move in the horizontal and vertical directions under the action of the fan, and when the hollow belt yarns move out of the radiation area of the fan, the hollow belt yarns fall onto the guide plate and slide out of the guide plate under the influence of gravity; the hot melt adhesive of the hollow tape yarn is cooled and solidified under the action of the fan, and the hollow tape can be quickly dried by the mode.

Furthermore, a vibration motor is fixed at the bottom of the guide plate.

The tail end of the guide plate is generally connected with a material box, and the hollow tape yarns can fall conveniently through a vibration motor.

Further, the setting process is heat steaming setting.

The heat-steaming shaping process is mature and has good effect.

Further, the hollow tape yarn is made of terylene or acrylic fiber or cotton.

In conclusion, the invention has the following beneficial effects: the scheme forms the covering yarn capable of being woven into fluffy cloth by improving the processing technology (hot melt drying and heat setting) of the covering yarn and improving the raw materials (selecting the hollow decorative yarn with the hexagonal cross section and weaving the hollow tubular structure in a flat-knitting and weft-knitting mode).

Detailed Description

The present invention will be described in further detail below.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.

A covering yarn, as shown in figure 1, is composed of a polyester solid yarn 0 and a decorative yarn 1, wherein the polyester solid yarn 0 is treated by a heat setting process. And false twisting is adopted for processing while the decorative yarn 1 and the polyester solid yarn 0 are wound.

The terylene solid yarn 0 is 300D, the decorative yarn 1 is 3.3N hollow tape yarn, the hollow tape yarn is a hollow tubular structure woven by a flat knitting and weft knitting mode, the raw material of the hollow tape yarn is 10S terylene or acrylic or cotton, and each layer of the hollow tubular structure consists of six loops 2 (as shown in figure 2). The hollow tape yarn is soaked in hot melt adhesive and dried to form a hollow tubular structure, wherein the mass ratio of the hot melt adhesive to the decorative yarn 1 is 1:10, and the hot melt adhesive is EVA hot melt adhesive.
