Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention generally relates to a yarn manufacturing method and a mixed yarn thereof.

2. Description of the Prior Art

Fleck fancy mixed yarns have long been favored by consumers due to the special appearance design and thus have relatively high marketability. However, a conventional fleck fancy mixed yarn is manufactured by spinning un-dyed fibers with pre-dyed fibers. In other words, dyed fibers of different color must be prepared for fleck fancy mixed yarns having different fleck color. The cost of the conventional manufacturing method of fleck fancy mixed yarn is relatively high, and the efficiency is hard to be increased. Therefore, a novel method to make a fleck fancy mixed yarn is needed.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a yarn manufacturing method to make a fleck fancy mixed yarn.

It is another object of the present invention to provide a yarn manufacturing method to make a fleck fancy mixed yarn more efficiently.

It is another object of the present invention to provide a mixed yarn having a fleck fancy effect.

The yarn manufacturing method includes providing a plurality of raw fibers, modifying at least one of the raw fibers to form at least one modified fiber, and spinning the raw fibers and the at least one modified fiber into a mixed yarn. The yarn manufacturing method further includes dyeing the mixed yarn.

The step of modifying the raw fiber includes attaching a modifier to the raw fiber. The modifier may include a cation modifier for enabling the modified fiber to be dyeable with an acidic dye. The modifier may include a color enhancer for increasing the affinity of the modified fiber to a dye. The modifier may include a hydrophobic agent for decreasing a hydrophile of the modified fiber. The modifier may include a hydrophobic oil-proof agent for enabling the modified fiber to be hydrophobic and oil proof. The modifier may include a sunlight resistant agent for enabling the modified fiber to be sunlight resistible.

In one embodiment, the raw fibers may include natural fibers which are selected from a group consisting of cotton fibers, wool fibers, linen fibers, jute fibers, ramie fibers, shengma fibers, and hemp fibers. In another embodiment, the raw fibers may be selected from a group consisting of polyethylene terephthalate polymers, polyamide 6 polymers, polyamide 66 polymers, Nylon 6 polymers, Nylon 66 polymers, polypropylene polymers, and polyolefin.

The mixed yarn of the present invention is spun from at least one raw fiber and at least one modified fiber, wherein the at least one modified fiber is modified from the at least one raw fiber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

A flow chart of a first embodiment of the present invention is shown in FIG. 1, wherein the yarn manufacturing method includes the following steps.

Step 1010, a step of providing a plurality of raw fibers is performed. In one embodiment, the raw fibers include natural fibers which are selected from a group consisting of cotton fibers, wool fibers, linen fibers, jute fibers, ramie fibers, shengma fibers, and hemp fibers. In another embodiment, the raw fibers can be selected from a group consisting of polyethylene terephthalate polymers, polyamide 6 polymers, polyamide 66 polymers, Nylon 6 polymers, Nylon 66 polymers, polypropylene polymers, and polyolefin.

Step 1030, a step of modifying at least one of the raw fibers to form at least one modified fiber is performed. The step of modifying the raw fiber includes attaching a modifier to the at least one raw fiber. More particularly, the modifier is attached to the surface of the at least one raw fiber by adsorption or absorption and is adhered to the surface of the at least one raw fiber after the at least one raw fiber is dried.

The modifier is configured to enable the fiber to have a predefined ability. In other words, different modifiers can provide the fiber with different abilities. For example, the modifier may include a cation modifier for enabling the at least one modified fiber to be dyeable with an acidic dye. The cation modifier is preferably but not limited to a material selected from a group consisting of a quaternary ammonium, a tertiary ammonium, an aluminum polymer, and a combination thereof. Furthermore, the modifier may include a color enhancer for increasing the affinity of the at least one modified fiber to a dye. The color enhancer is preferably but not limited to a material selected from a group consisting of a quaternary ammonium, a tertiary ammonium, an aluminum polymer, and a combination thereof. Moreover, the modifier may include a hydrophobic agent for decreasing a hydrophile of the at least one modified fiber. The hydrophobic agent is preferably but not limited to a material selected from a group consisting of fluorine-containing polymers, silicon-containing polymers, and a combination thereof. Furthermore, the modifier may include a hydrophobic oil-proof agent for enabling the at least one modified fiber to be hydrophobic and oil proof. The hydrophobic oil-proof agent is preferably but not limited to polytetrafluoroethylene. Moreover, the modifier may include a sunlight resistant agent for enabling the at least one modified fiber to be sunlight resistible. The sunlight resistant agent is preferably but not limited to a material selected from a group consisting of a UV absorbent, an infrared ray absorbent, a metal oxide, and a combination thereof.

Step 1050, a step of spinning the raw fibers and the at least one modified fiber into a mixed yarn is performed. More particularly, the raw fibers is spun with the at least one modified fiber into the mixed yarn with a ratio of 1% to 99%, wherein the mixed yarn may be spun with a variety of counts. Moreover, since the at least one modified fiber is modified from the at least one raw fiber, the composition of the mixed yarn is 100% raw fiber.

The advantage of the yarn manufacturing method of the present invention is described as below. As shown in FIG. 1, in the embodiment, the yarn manufacturing method further include step 1070, a step of dyeing the mixed yarn. For example, in a case of using the cation modifier as the modifier, only the modified fiber is dyeable when the mixed yarn is dyed with the acid dye. Therefore, the dyed mixed yarn will have fleck fancy effect, wherein the fleck color depends on the acid dye used in the dyeing step. In other words, in this embodiment, the fleck color of the fleck fancy mixed yarn manufactured according to the yarn manufacturing method of the present invention can be changed by changing the acid dye used in the dyeing step. It eliminates the need of preparing pre-dyed fibers in advance and then spinning raw fibers with the pre-dyed fibers as described in the conventional method.

In different embodiments, the steps of the yarn manufacturing method of the present invention are modified under the same concept. A flow chart of a second embodiment is shown in FIG. 2, wherein the yarn manufacturing method includes the following steps.

Step 2010, a step of providing at least one modified fiber which is modified from at least one raw fiber is performed.

Step 2030, a step of providing the at least one raw fiber is performed.

Step 2050, a step of spinning the at least one raw fiber and the at least one modified fiber into a mixed yarn is performed.

More particularly, in the first embodiment, a plurality of raw fibers is provided first. After that, at least one of the raw fibers is modified to form at least one modified fiber and then the raw fibers and the at least one modified fiber are spun into a mixed yarn. In the second embodiment, the modified fibers are directly provided, commercially purchased for example, to be spun with the raw fibers into a mixed yarn. Moreover, the modified fibers could be modified from first row fibers and then be spun with second raw fibers into a mixed yarn.

Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative. Further modification of the invention herein disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
