BACKGROUND OF THE INVENTION

1. Field of Invention

The present invention relates to a polyester fiber and lightweight woven nylon yarn blended process, and more particularly to a polyester fiber and lightweight woven nylon yarn blended process by which two lightweight processes in weaving procedures are employed to produce a fabric with lighter weight.

2. Related Art

China patent publication number CN100558978C titled “Microfibers Dyeing Method and Fabric Woven from the Dyed Microfibers” dated in 11 Nov. 2009 comprises a lightweight procedure, in which the microfibers are winded on a yarn dyeing machine, an alkaline reagent is added to the winded microfibers under an even temperature between 100 to 130° C., and maintained from 30 to 60 minutes to reduce the weight of the microfibers by 6 to 15%; a water rinse procedure, in which 70 to 80° C. nonferrous water is sprayed into the lightweight microfibers by a spray nozzle to eliminate impurities from the microfibers by water pressure, a cleaning agent is used for cleaning the microfibers, and the microfibers are undergone an acidic treatment to reach a PH value of 4 to 5; a water rinse procedure; and a water rinse and drying procedure.

The above conventional method uses the corrosive alkaline reagent to reduce the weight first, and the acidic treatment is further employed to balance the acidic and alkaline values. The discharging of the alkaline and acidic agents will cause environmental pollution and therefore does not conform to the environmental standards, which is one of the disadvantages.

Furthermore, the use of the corrosive alkaline reagent to reduce the weight first, and further the acidic treatment to balance the acidic and alkaline values is not only troublesome in operation, but will also increase the cost of work time. Additionally, the alkaline reagent and the acidic reagent used for balancing will increase the cost of consumables and therefore does not conform to the economical effectiveness, which is another one of the disadvantages.

Lastly, the finished product produced employing the above troublesome operation is merely yarn, which only belongs to the preliminary procedure in producing a fabric as the finished product. The absence of fabric as the finished product further exposes the disadvantages of time and work consuming and troublesome.

SUMMARY OF THE INVENTION

The present invention of a polyester fiber and lightweight woven nylon yarn blended process aims to solve the drawbacks of the conventional method mentioned above, which are environmental pollution caused by the use of the alkaline agent and the balancing acidic agent, and the increase of costs caused by troublesome in the preliminary procedures in producing a fabric, and yet cannot obtain the fabric as the finished product.

A primary objective of the present invention is to provide a polyester fiber and lightweight woven nylon yarn blended process which does not require the use of the alkaline agent and the balancing acidic agent in order to avoid environmental pollution.

A secondary objective of the present invention is to provide a polyester fiber and lightweight woven nylon yarn blended process which does not require the troublesome operation in using corrosive alkaline reagent and the acidic treatment for balancing afterwards, and therefore can reduce the costs and is economically effective.

A third objective of the present invention is to provide a polyester fiber and lightweight woven nylon yarn blended process which does not require troublesome preliminary procedures and can still produce a fabric with a lighter weight as the finished product directly through processing lightweight procedures two times.

The present invention of a polyester fiber and lightweight woven nylon yarn blended process comprises following procedures of:

a lightweight weaving procedure A, in which a plurality of chemical monofilament fibers is twirled into bunched chemical monofilament fibers by a kneading process, the bunched chemical monofilament fibers and a woven complex yam (polyester fiber and woven nylon yarn) are fed into a yarn entrance of a loom simultaneously, the loom is equipped with a fiber opening knife for performing a fiber opening process for the woven complex yarn, the fiber opening knife performs the fiber opening process to cut the woven complex yarn into a plurality of equal sized furcal structures longitudinally to cause wear and tear to achieve lightweight preliminarily, then the furcal structures and the bunched chemical monofilament fibers are undergone a knitting process to obtain a lightweight fabric;

a secondary lightweight procedure B, in which the lightweight fabric woven using the previous procedure is washed with 130° C. water to cause further partial damage to the nylon in the woven complex yarn of the lightweight fabric by the water temperature 10° C. higher than the temperature (not over 120° C.) that the nylon can endure in order to achieve lightweight the second time;

a dyeing procedure C, in which a dye, a dispersant agent, a leveling agent, an antistatic agent and a softening agent are added together for dyeing the lightweight fabric under pressure; and

a water rinsing and drying procedure D, in which the dyed lightweight fabric is washed with water and dried for obtaining the finished product of the present invention.

The bunched chemical monofilament fibers are kneaded from the chemical monofilament fibers to have a thickness of 150 to 500 deniers.

The chemical monofilament fibers are selected from polypropylene chemical monofilament fiber, nylon chemical monofilament fiber, or polyester chemical monofilament fiber.

The woven complex yarn has a thickness of 50 to 320 deniers.

The present invention will become more fully understood by reference to the following detailed description thereof when read in conjunction with the attached drawings.
