Abstract
A method for manufacturing wet absorption yarns comprises the following steps of fabricating the polypropylene filaments into yarns; feeding the yarns to a false twisting machine for twisting the yarns; feeding the yarns to a driving roller and a package rollers for twisting the yarns to be as twisting yarns; transferring the twisting yarns to at least one brush roller with short brushes on the surface of the roller so that hairs are formed on the twisting yarns to be as haired twisting yarns; feeding the haired twisting yarns to at least one grooved roller; feeding the haired twisting yarns to at least one guiding wheel to be stretched and drying the haired twisting yarns; and outputting the haired twisting yarns as wet absorption yarns. Moreover, a wet absorption yarns is disclosed, where wet absorption yarns made from polypropylene filaments. The wet absorption yarns is twisted, haired and permeated with wet absorber.
Description




BACKGROUND OF THE INVENTION




1) Field of the Invention




The present invention relates to wet absorption yarns, and in particular to method for manufacturing wet absorption yarns and the yarns manufactured from the method.




2) Description of the Prior Art




Conventionally, wet absorption fabrics are made by modifying the structure of the fabrics or permeating wet absorber into fabrics or yarns so that the fabrics have the function of absorbing water and thus the fabrics have many functions, such as wiping, absorbing sweat of the body and thus draining the sweat from the body.




Conventionally, adding wet absorber to fabrics likes the dying process. The yarns or fabrics are sunk in wet absorber or sputtered with wet absorber. The difficult of this process is that the adding process is completely isolated from other manufacturing process of the fabrics. In the process, the manufacturers must transfer, sink (or sputter), drying the yarns or fabrics. These extra steps make the process to be time and labor consumed so that the cost of the yarns or fabrics is expensive.




Moreover, the sputtering process induces a weak fastness, while the sinking process will induce that too much wet absorber is permeated into the yarns or fabrics so that too much of the wet absorber is used and a longer time is required to dry the yarns or fabrics. Moreover, the products are hard so that a bad feeling is presented.




SUMMARY OF THE INVENTION




Accordingly, the primary object of the present invention is to provide a method for manufacturing wet absorption yarns. The method comprises the following steps of fabricating the polypropylene filaments into yarns; feeding the yarns to a false twisting machine for twisting the yarns; feeding the yarns to a driving roller and a package rollers for twisting the yarns to be as twisting yarns; transferring the twisting yarns to at least one brush roller with short brushes on the surface of the roller so that hairs are formed on the twisting yarns to be as haired twisting yarns; feeding the haired twisting yarns to at least one grooved roller; feeding the haired twisting yarns to at least one guiding wheel to be stretched and drying the haired twisting yarns; and outputting the haired twisting yarns as wet absorption yarns. Moreover, a wet absorption yarns is disclosed, where wet absorption yarns made from polypropylene filaments. The wet absorption yarns is twisted, haired and permeated with wet absorber.




The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION




Referring to

FIG. 2

, the method of manufacturing wet yarns and the product from the same are illustrated. The yarns are made from polypropylene filaments without capillary pores thereon. The method comprises the following steps of:




Fabricating the polypropylene filaments into yarns;




Feeding the yarns to a false twisting machine for twisting the yarns.




Feeding the yarns to a driving roller


11


and a package roller


12


for twisting the yarns to be as twisting yarns R


1


.




Transferring the twisting yarns R


1


to at least one brush roller


2


with short brushes on the surface of the roller


2


so that hairs are formed on the twisting yarns R


1


so as to be as haired twisting yarns R


2


(referring to FIG.


2


-A).




Next, feeding the haired twisting yarns R


2


to at least one grooved roller


3


.




Next, feeding the haired twisting yarns R


2


to at least one guiding wheel


4


to be stretched and drying the haired twisting yarns R


2


, and then outputting the haired twisting yarns as wet absorption yarns R


3


.




In the bottom


31


of a trench of the grooved roller


3


is placed wet absorber P. When the haired twisting yarns R


2


passes through the grooved roller


3


; the wet absorber P will permeate into hairs R


2


, of the haired twisting yarns R


2


(referring to FIG.


3


B). The wet absorber P will be completely adhered to the yarns in the following stretching process (referring to FIG.


5


). Thereby, cloth made of this wet absorption yarns R


3


will have functions of water absorption and draining.




From above

FIGS. 3

,


3


-A and


3


-B, the wet absorber P is uniformly coated on a surface of the bottom


31


of the grooved roller


3


. The haired twisting yarns R


2


is fed into the grooved roller continuously so that the wet absorber P in the bottom


31


will be coated on the haired twisting yarns R


2


from the upper side of the haired twisting yarns R


2


.




Moreover, as shown in FIGS.


4


and


4


-A, a material inlet


32


is formed at a center of the grooved roller. A plurality of penetrating holes


321


are formed around the material inlet


32


so that the wet absorber P can be fed into the material inlet


32


. With the rotation of the grooved roller, the wet absorber P will flow to a surface of the bottom


31


of the grooved roller so as to coat on the haired twisting yarns R


2


continuously.




Although the present invention has been described with reference to the preferred embodiments, it will be understood that the invention is not limited to the details described thereof. Various substitutions and modifications have been suggested in the foregoing description, and others will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
