BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a dust control mop yarn obtained by regenerating a fiber that has not been conventionally used, and a method for producing the same.
[0002]
[Prior art]
A dust control mop that effectively collects dust such as dust and cotton dust indoors is known.
The dust control mop is usually configured such that mop yarn is planted on a base fabric formed of thick fabric such as canvas, and the base fabric is detachable from the mop handle, In order to further enhance the action of adsorbing and holding the dust adhering to the mop yarn by the rubbing of the mop yarn, the mop yarn is coated or impregnated with a dust adsorbing liquid. Examples of such a dust adsorbing liquid include oils such as liquid paraffin, spindle oil, alkylbenzene oil, diester oil, castor oil, and aqueous dust adsorbent.
[0003]
However, conventional dust control mop yarns rub against the floor surface during use and are subjected to harsh washing conditions even after use. As a result, the overall length of the yarn is shortened, resulting in poor cleaning efficiency and a reduced dust control function.
On the other hand, in consideration of environmental issues in recent years, dust control mop yarn (hereinafter referred to as “eco-yarn”), which is made from recycled fiber that has not been used in the past, such as short fibers generated in the spinning process and cotton wool, is used. .) Has come to be desired.
[0004]
However, since unused fibers that have not been used in the past have a short fiber length, the percentage of unused fibers is limited to 20% by weight. There was a problem of disappearing.
In addition, conventional dust control mop yarn has been manufactured by the cotton spinning method and synthetic fiber spinning method, but the fiber spinning method and synthetic fiber spinning method are very limited because the fiber length and fiber denier (thickness) of the raw material are unified. Therefore, if unused fibers with irregular fiber lengths and fiber deniers are used, strength irregularities due to irregular fiber lengths, irregular fiber deniers, and irregularity in fiber parallelism may occur. It was necessary to correct.
[0005]
[Problems to be solved by the invention]
Therefore, the problem to be solved by the present invention is that the yarn can be prevented from being worn, and even if the proportion of unused fibers is increased to 50% by weight or more, the tensile strength and wear strength are sufficiently large, and the fiber lengths are not uniform. It is another object of the present invention to provide a dust control mop yarn (eco yarn) and a method for producing the same, which do not hinder even if the fiber denier is uneven.
[0006]
[Means for Solving the Problems]
The eco-yarn of the present invention for solving the above problems is a fiber that can be re-spun by a warp process of short fibers generated during the spinning process, cotton falling, or yarn waste generated during the spinning process or woven process. Spinning a sliver in which unused fibers made of cotton formed by reduction to a state, a reinforcing chemical fiber having a fiber length longer than the unused fibers, and a low-melting-point binder synthetic fiber are mixed. It consists of the obtained single yarn or twisted yarn of the single yarn, and the fibers in the single yarn or in the twisted yarn are bonded and fused together by the melt of the binder synthetic fiber. is there.
[0007]
The eco-yarn of the present invention having the above-described configuration is obtained by reducing short fibers generated in the spinning process, cotton falling, or yarn waste generated in the spinning process and the woven process into a fiber state that can be re-spun by the lapping process. A sliver obtained by spinning a sliver in which an unused fiber such as cotton, a reinforcing chemical fiber having a fiber length longer than the unused fiber, and a low-melting binder synthetic fiber is blended. A single yarn or a twisted yarn of the single yarn, and the fibers in the single yarn or in the twisted yarn are bonded and fused to each other by the melt of the binder synthetic fiber. In addition to being mixed, even if the proportion of unused fibers with a short fiber length is increased, the unused fibers are bonded and fused together by a reinforcing chemical fiber or a binder synthetic fiber and a melt of the binder synthetic fiber. Yo , Tensile strength and abrasion strength is sufficiently large, no problem even if there is uneven irregular or fibers denier fiber length, it is possible to prevent even escape of fibers from the yarns, wear of the thread can be prevented.
[0008]
In addition, the eco-yarn manufacturing method of the present invention for solving the above-mentioned problems includes an anti-wrist process for reducing yarn waste generated in the spinning process and the weaving process into a fiber state that can be spun again, and in the spinning process. A blending step of blending short fibers generated, cotton obtained by a fluffing or fluffing process, a reinforcing chemical fiber having a longer fiber length, and a binder synthetic fiber having a low melting point; and the blended fiber A spinning process in which a single yarn is produced by a spinning method using a capacitor card (spun card), and a heat treatment process in which the single yarn or the twisted yarn of the single yarn is heat-treated at a temperature higher than the melting point of the binder synthetic fiber. It is a feature.
[0009]
The production method of the eco yarn of the present invention having the above-described configuration includes the above-mentioned repelling step, the above blending step, the above spinning step, and the above heat treatment step. Therefore, the reinforcing fiber has a longer fiber length than the unused fiber or the unused fiber. The sliver can be mixed with chemical fibers and low-melting-point binder synthetic fibers. Unlike the cotton spinning method and synthetic fiber spinning method, the usable range of raw materials is widened, and the fiber length and fiber denier are not uniform. Even if the unused fiber is used as a raw material, there is no problem.
[0010]
In addition, by melting the binder synthetic fiber, the unused fiber, the reinforcing chemical fiber, and the binder synthetic fiber are bonded and fused to each other by the melt of the binder synthetic fiber. Even if the ratio is increased, the tensile strength and the wear strength can be sufficiently increased, and the fibers can be prevented from coming out of the yarn, so that the yarn can be prevented from being worn.
[0011]
In a preferred embodiment of the eco yarn of the present invention and the method for producing the same, the mixing ratio of the unused fiber is 5 to 70% by weight, the mixing ratio of the binder synthetic fiber is 5 to 40% by weight, and the rest is used for the reinforcement. The binder synthetic fiber can be a polyester fiber or a nylon fiber, and the reinforcing chemical fiber can be a rayon fiber.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
As described above, the eco yarn according to the present invention basically re-spins the short fiber generated during the spinning process, the cotton falling, or the yarn waste generated during the spinning process or the woven process through the re-wrist process. A sliver made by blending an unused fiber made of cotton formed by reduction to a possible fiber state, a reinforcing chemical fiber having a longer fiber length than the unused fiber, and a low-melting binder synthetic fiber is refined. A single yarn obtained by spinning or a twisted yarn of the single yarn and having a structure in which the fibers in the single yarn or in the twisted yarn are bonded and fused together by the melt of the binder synthetic fiber. It is.
[0013]
In addition, the production method of the present invention for producing the above-described eco yarn is generated in the spinning process, in which the yarn waste generated in the spinning process and the woven process is reduced to a fiber state that can be spun again, and in the spinning process. A blending process of blending short fibers, cotton obtained by a fluffing or fluffing process, a reinforcing chemical fiber having a fiber length longer than those, and a binder synthetic fiber having a low melting point, and the blended fibers in a condenser card A spinning process in which a single yarn is produced by a spinning method using the above, and a heat treatment process in which the single yarn or the twisted yarn of the single yarn is heat-treated at a temperature equal to or higher than the melting point of the binder synthetic fiber.
[0014]
More specifically, fibers that can be reused include (1) cutting waste and tears generated in the process of producing clothing, and (2) short fibers generated in the production process of cotton yarn and blended yarn at spinning mills. And cotton fall (comb fall cotton, flat cotton, sliver fall cotton), (3) regenerated fibers such as garments that have become waste, etc., as unused fibers in the present invention, Among them, the fiber of the above (2), which is relatively stable in quality, is used. Furthermore, among the yarn waste generated in the spinning process and the weaving process, 100% cotton yarn waste can be selected and spun. A fiber state that can be spun again by this work process by cutting it to a length and passing it through a device called a cylinder 4-8 times while the cotton yarn waste passes through the warp machine. Recycled cotton (pure cotton yarn waste anti-wool cotton It is used.
[0015]
In this way, the unused fiber regenerated into a fiber state that can be re-spun is applied to a blender together with a reinforcing chemical fiber having a fiber length longer than that of the unused fiber and a low-melting-point binder synthetic fiber in a blending process. Mix the fiber with the.
As the low melting point binder synthetic fiber, a low melting point polyester fiber or a low melting point nylon fiber is used. The low melting point polyester fiber and the low melting point nylon fiber have a property of melting at about 80 to 130 ° C. As the reinforcing chemical fiber, rayon fiber is preferably used, but other chemical fiber may be used.
[0016]
In the blending step, the unused fiber is mixed in an amount of 5 to 70% by weight (more desirably 30 to 50% of the whole), and the low melting binder synthetic fiber is 5 to 40% by weight (more desirably). 10-30% of the total), and the remaining amount of the rayon fiber, which is longer than the unused fiber, is mixed. For example, when 50% by weight of the unused fiber and 20% by weight of the binder synthetic fiber having a low melting point are mixed, the remaining 30% by weight of the rayon fiber is mixed.
[0017]
The blended fibers are supplied to the spinning card in the carding process, and the entangled fibers are loosened in the process of passing through the cylinder of the spinning card. After passing through this cylinder 2-4 times, the exit of the machine base It is passed through the condenser device at, and becomes a sliver called “shino”.
In the part of the condenser device, the condenser rubber moves to the left and right while the Shino is being sent out, forming a non-twisted rounded yarn state, which is wound into a thin cylindrical shape by the winding device. .
[0018]
Next, the yarn produced in the carding step is subjected to a single yarn twist by a ring spinning machine in the fine spinning process to form a raw yarn (single yarn), which is wound around a bobbin. The single yarn can be further passed through a ring twisting machine to form a twisted yarn such as a twin yarn (two twisted yarn), a three twisted yarn, or a four twisted yarn.
[0019]
Next, the single yarn or the twisted yarn of the single yarn is heat-treated at a temperature equal to or higher than the melting point of the binder synthetic fiber in a heat treatment step.
The heat treatment is performed by heating the twisted yarn with hot air, steam, or high-temperature water at 80 to 130 ° C. to melt the low-melting-point binder synthetic fiber, and the fiber in the single yarn or the twisted yarn of the single yarn They are bonded and fused together by the melt of the binder synthetic fiber.

Unlike the cotton spinning method and synthetic fiber spinning method, the usable range of raw materials is widened. There is no problem even if unused fibers having irregular lengths and fiber deniers (thicknesses) are used as raw materials.
[0021]
The eco-yarn manufacturing method includes a spinning process in which the sliver is spun into a single spinning machine, and a heat treatment process in which the single yarn or the twisted yarn of the single yarn is heat-treated at a temperature equal to or higher than the melting point of the binder synthetic fiber. Therefore, the unused fibers of the single yarn or the twisted yarn, the reinforcing chemical fiber having a long fiber length, or the binder synthetic fiber are bonded and fused together by the melt of the binder synthetic fiber.
Therefore, the eco yarn produced by the above production method is formed by bonding the fibers of the yarn to each other by the melt of the binder synthetic fiber, so that the unused fiber is a short fiber or the fiber length or fiber denier is Even if they are not uniform, the tensile strength and the wear strength are sufficiently large, and the fibers can be prevented from coming out of the yarn, so that the yarn can be prevented from being worn.
[0022]

[0023]
The eco yarn is a single yarn obtained by spinning a sliver in which an unused fiber, a reinforcing chemical fiber having a longer fiber length than the unused fiber, and a low-melting binder synthetic fiber are mixed, or a twisted yarn of the single yarn Therefore, these fibers are sufficiently mixed together, and the unused fibers, the reinforcing chemical fibers having a long fiber length, and the binder synthetic fibers are bonded and fused to each other by the melt of the binder synthetic fibers. Therefore, even if the unused fiber is a short fiber or the fiber length and the fiber denier are not uniform, the tensile strength and the wear strength are sufficiently large, and the fiber can be prevented from coming out from the yarn surface and the yarn tip.
Therefore, even if the percentage of unused fiber is increased, the tensile strength and wear strength are sufficient, and there is no problem even if the unused fiber is short fiber or the fiber length or fiber denier is not uniform. The thread can be prevented from slipping out, so that the thread can be prevented from being worn.
