Background

Through the development of many years, the nylon production is gradually mature and stable in technology, the productivity is expanded year by year, the market tends to be saturated, and the conventional variety competition is more and more intense. With the development of the market, people have higher and higher dress, and not only the requirement on high quality is met, but also the individuation and differentiation of dress are pursued.

However, with the development of the market, the conventional coated yarn cannot meet the market demand. Therefore, the difference of chinlon and special yarn products have good prospects in meeting the market and improving the market competitiveness.

The nylon spandex air-coated yarn is an important way for improving the nylon differentiation. The existing nylon spandex air-coated yarn has a single expression form and still cannot meet the market demand. In order to improve the competitiveness of enterprises, the air-coated nylon yarn needs to be developed into a product with market competitiveness.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a problem based on present polyamide fibre provides a polyamide fibre air cladding silk, specifically is a different fine heterochrosis flexible air cladding silk of polyamide fibre, through this kind of product, realizes having the double-colored effect of natural cotton material to the product differentiation of polyamide fibre chemical fibre has been enriched, has improved industry competitiveness.

The utility model provides a technical scheme that its technical problem adopted is:

the different-color flexible air-coated nylon yarn comprises a spandex yarn and a nylon filament yarn, wherein the nylon filament yarn and the spandex yarn are subjected to high-pressure air regular jet-pressing to form a coating structure of the nylon filament yarn-coated spandex yarn, the spandex yarn and the nylon filament yarn are both composed of a plurality of strands of monofilaments, the nylon filament yarn is a mixed yarn composed of nylon FDY and nylon POY, in the mixed yarn, part of monofilaments in the nylon POY are broken, the percentage of the broken monofilaments is 5-10%, and the spandex yarn is formed by two groups of spiral windings.

The existing nylon air-coated yarns are all single-color in color, and the prepared air-coated yarns do not have cotton feeling. The scheme adopts two kinds of filament mixed fibers of polyamide fibre FDY and polyamide fibre POY and then processes with the spandex silk to utilize two kinds of different materials of physical properties to reach the performance complementation. The chinlon FDY has the characteristics of high strength and high elasticity, but has poor hygroscopicity and poor product expression, while the chinlon POY can cause part of monofilaments to break through a stretching process, and the broken monofilaments form the characteristics of natural cotton. After the two materials are mixed, the dual-performance effect is achieved.

Preferably, the chinlon FDY and the chinlon POY are bicolor. In order to further improve dichroism, the two materials adopt a bicolor expression form.

Preferably, the stretching ratio of the chinlon POY before blending with the chinlon FDY is 1.1-1.15, and the stretching ratio of the chinlon FDY and the chinlon POY after line mixing is 1.02-1.05.

Preferably, the number of strands of the monofilament of the chinlon POY is 24-48; the number of the chinlon FDY strands is 16-30.

Preferably, the nylon filament is mixed fiber of 93 dtex/48F white POY and 30D/24F FDY.

Preferably, the cross section of the chinlon POY is a rhombic profiled fiber.

Preferably, the air-coated filaments have a reticulation of 94 ± 8%.

The utility model has the advantages that: part of monofilaments in the chinlon POY are in a broken state through a stretching process, so that the cotton feeling of the chinlon POY is improved; the nylon POY and the nylon FDY are mixed and fresh, so that the dyed fabric has the effect of depth; finally, the dyed fabric has two properties of double color and cotton feeling, so that a client has a larger space for developing the fabric, and the application range of the product can be enriched.

Detailed Description

The technical solution of the present invention is further specifically described below by way of specific examples. In the utility model, if not, the adopted raw materials and equipment can be purchased from the market or commonly used in the field. The methods in the following examples are conventional in the art unless otherwise specified.

The scheme improves the nylon heterochromatic flexible air-coated yarn, which is an air-coated yarn product showing dual performance by utilizing two raw materials with physical properties.

Specifically, the air-coated yarn comprises a spandex yarn and a nylon filament yarn, and the nylon filament yarn and the spandex yarn are subjected to high-pressure air regular spray pressing to form a coating structure of the nylon filament yarn-coated spandex yarn, wherein the spandex yarn and the nylon filament yarn are both composed of a plurality of strands of monofilaments. The nylon yarn is a mixed fiber composed of nylon FDY and nylon POY, and the number of strands of the single yarn of the nylon POY is 24-48; the number of the chinlon FDY strands is 16-30; in the mixed fiber composed of the nylon and the POY, part of monofilaments in the nylon POY are broken, the percentage of the broken monofilaments is 5-10%, and the spandex filaments are formed by two groups of spiral winding.

Because the variety adopts two raw materials of FDY and POY, the POY firstly goes to a roller for cold drawing, the drawing ratio is controlled to be about 1.15, so that the cotton type effect can be achieved through subsequent heating and false twisting under the condition of low drawing ratio, and the size of the drawing ratio determines the quality of the cotton type effect. The POY is stretched and then enters a roller together with the FDY, and the stretching ratio of the POY and the FDY is 1.02-1.05. FDY is adopted to increase the strength and the framework of the variety, excessive drafting can be realized if the stretching ratio is too large, normal production cannot be realized, and stiff silk can be formed if the false twisting tension is too small if the stretching ratio is too small. The false twister must use a 1-7-1 combination to have sufficient twist to ensure a cotton feel.

In this particular production, the raw materials were blended with the conventional 93 dtex/48F white POY and 30D/24F FDY of the same company, draw texturing was performed using a macro-source V-draw texturing machine, and the air-covered filaments had a network of 94. + -. 8%.

The elastic coating effect of the air-coated yarn is further improved, and the cross section of the polyamide POY is a rhombic profiled fiber.

Part of monofilaments in the chinlon POY are in a broken state through a stretching process, so that the cotton feeling of the chinlon POY is improved; the nylon POY and the nylon FDY are mixed and fresh, so that the dyed fabric has the effect of depth; finally, the dyed fabric has two properties of double color and cotton feeling, so that a client has a larger space for developing the fabric, and the application range of the product can be enriched.

It will be apparent to those skilled in the art that the embodiments described above are not intended to be exhaustive or to limit the embodiments to the precise forms disclosed. It will be apparent to those skilled in the art that certain modifications, combinations, and variations can be made in light of the above teachings.
