Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a fiber cheese processing agent composition, and more specifically, to impart smoothness and flexibility to a yarn fiber product, and at the same time, in cheese processing. The present invention relates to a fiber cheese treating agent composition exhibiting excellent adhesion.

[Conventional technology]

Conventionally, for a yarn fiber product, it is necessary to impart excellent smoothness and favorable flexibility to the yarn in order to smoothly perform weaving and knitting. As a weaving treatment agent used for such purpose, a composition comprising various waxes, fats and oils, surfactants and the like (for example, Japanese Patent Publication No. 57-19225, Japanese Patent Publication No. 60-52230, etc.) is a so-called weaving treatment agent. It has been proposed as a softening agent.

By the way, there is a cheese processing method as one of the fiber processing methods. This processing method can process a large amount of yarn at a time, and has the advantage of streamlining fiber processing.
There is a problem that adhesion of the fiber treatment agent to the yarn is poor. In addition, there is also a disadvantage that a burden is imposed on wastewater treatment because the fiber treatment agent remaining in the treatment liquid must be discarded.

In the above-mentioned cheese treatment method, as a means for improving the adhesion of the fiber treating agent to the yarn, there is a method of applying a cationic surfactant or increasing the emulsion particle diameter. However, when a cationic surfactant is used, the adhesion is improved, but the yarn is colored by heat or a fluorescent dye is used in a yarn or the like. Is limited.

Also, when the particle size of the emulsion is increased, the fiber treatment agent unevenly adheres to the yarn and a stable treated yarn cannot be obtained. From the above-mentioned circumstances, for the cheese processing step including the fluorescent bleached thread, unless the amount of the fiber treating agent of the above-mentioned conventional technique is reduced and treated, the stable thread physical properties cannot be obtained. is there.

[Problems to be solved by the invention]

The present invention has been made in view of the above-mentioned current situation, in addition to smoothness, flexibility, and also has improved adhesion to a thread, particularly in cheese processing. It is an object of the present invention to provide a fiber cheese treating agent composition that provides excellent adhesion, smoothness, and preferable flexibility.

[Means for solving the problem]

In order to achieve the above object, the inventors of the present invention have conducted intensive studies on the adhesiveness to a yarn shape in cheese processing and the relationship between the yarn physical properties and the treatment agent composition. And a composition for imparting smoothness and favorable flexibility were found, and the present invention was completed.

That is, the treatment composition for fiber cheese of the first invention (hereinafter, simply referred to as a composition) comprises: (1) a wax having a melting point of 40 to 80 ° C., (2) a glyceride containing 10 to 40% by weight of monoglyceride, And (3) HLB contains 14 or more nonionic surfactants,
Further, it is characterized by not containing a cationic surfactant.

When the total of the wax, the glyceride and the nonionic surfactant is 100 parts by weight, the composition of the second invention has (1) 70 to 85 parts by weight of the wax, and (2) 10 to 35 parts by weight of the glyceride. And (3) the nonionic surfactant is contained in a proportion of 2 to 10 parts by weight.

 Hereinafter, the components of the present invention will be described in detail.

(Wax) The wax used in the present invention is a component for imparting smoothness to the yarn.

Examples of the wax used in the present invention include natural and synthetic hydrocarbon waxes, glycerides and waxes, and oxides and acid-modified products thereof. Natural waxes include hydrogenated hardened fats and oils obtained by hydrogenating beef tallow or lard, beeswax, spermaceti, hydrogenated spermaceti, carnauba wax, candelilla wax, wood wax, bran wax and other animal and plant waxes, paraffin wax, Mineral waxes such as microcrystalline wax, montan wax and sericin wax can be mentioned. Examples of the synthetic wax include a low molecular weight polyethylene wax, a polypropylene wax, and a wax obtained by a Fischer-Tropsch method.

The melting point of this wax must be 40-80 ° C. If the melting point of the wax is lower than 40 ° C., sufficient smoothness cannot be obtained. On the other hand, if the melting point of the wax exceeds 80 ° C., defective removal is likely to occur in the refining process after forming the fabric, which causes uneven dyeing in the subsequent dyeing process.

(Glyceride) Glyceride used in the present invention is a component for imparting flexibility to the yarn fiber.

As fatty acids of glycerides and monoglycerides, higher fatty acids having 14 or more carbon atoms, synthetic fatty acids, fatty acids obtained from natural fats and oils, and the like can be used. For example, palmitic acid, stearic acid, oleic acid, isostearic acid, hardened tallow fatty acid and the like can be mentioned.

In addition, the present glyceride needs to contain 10 to 40% by weight of monoglyceride. Preferably 10 to 30% by weight
Is appropriate. Monoglyceride content is 10% by weight
If it is less than 1, the emulsifiability of the composition will be poor and the adhesion to the yarn will be non-uniform. If the content exceeds 40% by weight, the emulsifiability of the composition deteriorates and the adhesion to the yarn becomes uneven, which is not preferable. If this is 10-30% by weight,
This is because both the emulsifiability of the composition and the uniform adhesion to the filament form are excellent.

The content of the glyceride containing the monoglyceride is suitably in the range of 10 to 35% by weight. If the glyceride content is less than 10% by weight, the flexibility of the yarn is reduced, and if it exceeds 35% by weight, the smoothness is poor, which is not preferable.

(Nonionic surfactant) The nonionic surfactant in the present invention is used for stably emulsifying the above-mentioned components in water. The nonionic surfactant used in the present invention includes polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbite fatty acid ester, polyoxyethylene glycol fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, Oxyethylene castor oil ether, polyoxyethylene resin-hardened castor oil ether and the like can be mentioned.

The nonionic surfactant must have an HLB of 14 or more. Further, the amount of the nonionic surfactant added is 10 to 1 with respect to 100 parts by weight of the glyceride of the component (2).
A range of 00 parts by weight is suitable. If the HLB is less than 14, or the added amount is less than 10 parts by weight, the emulsification is unstable and the adhesion to the yarn becomes uneven, which is not preferable. On the other hand, if the amount exceeds 100 parts by weight, a stable emulsion can be obtained, but the adhesion to the yarn is undesirably reduced.

(Other Optional Components) The composition of the present invention can appropriately contain a preservative, a fungicide, an antifoaming agent, and / or an antioxidant, in addition to the above essential components.

(Production Method) The composition of the present invention can be produced by the following method. For example, a predetermined amount of wax, glyceride and a nonionic surfactant are mixed, heated to 80 to 90 ° C., and stirred for about 30 minutes. Next, the obtained mixture is put into a container and cooled to room temperature to produce a solid block. The obtained solid block body is provided and used in an arbitrary form such as a flake form.

(Method of Use) To treat fibers with the present composition, for example, the following method can be used. That is, a predetermined amount of water is placed in a dissolving pot or a processing pot, heated to 85 ° C. or higher, and then the present composition is added and diluted while stirring.

The present composition includes natural fibers such as cotton and wool, regenerated fibers obtained by a viscose method or a copper-ammonia method, semi-synthetic fibers such as acetate fibers, synthetic fibers such as acrylic fibers and polyesters, and cotton and yarn obtained by mixing these. And the like can be applied when processing various fibers with a cheese dyeing machine. While circulating the treatment solution prepared by the above method at 80 to 90 ° C. for 10 to 30 minutes, the cheese winding thread is immersed in this solution. The flow direction of the treatment liquid is basically from the inner layer to the outer layer of the cheese, but may be combined from the inner layer to the outer layer from the outer layer to the inner layer. In addition, the flow rate of the processing solution is generally set at a set value of the cheese dyeing machine (for example,
30 / min / kg of yarn). The drying temperature of the processor is usually 100 to 120 ° C.

2. Performance Evaluation Test In order to clarify the performance of the present composition, performance evaluation was performed on each of the above compositions. The test method and evaluation items were performed under the following conditions, and the results are shown in Table 2.

[Test conditions]; 1) Cheese testing machine: 1 kg cheese testing machine manufactured by HISAKA Corporation 2) Yarn: 100% cotton bleached, # 40 double yarn 1 kg 3) Fluorescent paint: Illuminal SP Conc; 0.44 g /, Illuminal RG200; 0.14 g / 4) Treatment agent for fiber cheese: 2.2% owf (weight% of treatment agent with respect to yarn) 5) Bath ratio (yarn / treatment agent): 1/10 Oiling: 85 ° C, 15 minutes from inner layer to outer layer of cheese 6) Dehydration: 5 minutes from outer layer to inner layer of cheese 7) Drying: 110 ° C, 50 minutes from inner layer to outer layer, 110 ° C, 5 minutes from outer layer to inner layer 8 ) Pump flow rate: 30 / min / 1 kg of yarn [Evaluation items]; 1) Amount of adhering oil The test was carried out according to Japanese Industrial Standards (JISL1095). That is,
10 g of the yarn was collected from each of the inner, middle and outer layers of the cheese, and Soxhlet extraction was performed with a mixed solvent of alcohol and benzene at a volume ratio of 1: 2 to determine the adhesion amount. The display unit is% by weight.

2) Adhesion rate of processing agent (%) Before and after the treatment, 200 ml of each of the treatment liquid was sampled, and the concentration of non-volatile components (% by weight) was measured.

Treatment agent adhesion rate (%) = (Non-volatile content of liquid after treatment / Non-volatile content of liquid before treatment × 0.98)
× 100 3) Dynamic friction coefficient The dynamic friction coefficient between the friction body and the yarn was measured using a dynamic friction coefficient measuring device. In this case, the yarn speed was 100 m / min, the friction body was a stainless steel φ25 mm rod, and the contact angle was 180 degrees.

4) Hand The treated yarn was evaluated by handling by 10 judges. ◎ indicates soft, は indicates normal, and × indicates inferior.

3. Effect of Example As shown in Tables 1 and 2, a glyceride of 60% monoglyceride was used as in Comparative Example 1, a glyceride of 50% was used as in Comparative Example 2, and an HLB of 14 or less was used. When a surfactant is used, the emulsifiability of the composition becomes non-uniform, and the adhesion to the filaments becomes extremely non-uniform in the inner, middle and outer layers, and the adhesion rate decreases. In Comparative Example 2, the addition amount of the surfactant was 15%, which is out of the range of the second invention. Also,
Even when only the HLB of the surfactant is small and deviates from the range of the present invention as in Comparative Example 3, the emulsification is similarly unstable and shows non-uniform adhesion. Comparative Example 4 was a case where a wax having a melting point of about 38 ° C. was used, and did not show sufficient smoothness.

On the other hand, in Examples 1 to 4 (satisfying both ranges of the first and second inventions), the emulsification was very stable and uniform, the uniformity of adhesion and the adhesion rate were very excellent, and the smoothness was further improved. The properties and flexibility are also good. In Example 5, when only the amount of glyceride added was as large as 40% and deviated from the range of the second invention, the smoothness was slightly lowered. If only the amount of the surfactant added is outside the range of the second invention as in Example 6, the emulsification is slightly unstable and the adhesion is slightly non-uniform. However, all show sufficient practical performance.

〔The invention's effect〕

The composition of the first invention can impart excellent smoothness and flexibility to the fiber, and when the fiber is treated with the composition, especially when it is subjected to cheese treatment, the composition has excellent adhesion to a thread. The quality and the like can be improved.
In particular, according to the composition of the second aspect of the present invention, the above effects are further excellent.

As described above, if the compositions of the first and second inventions are used,
There is no need to use a cationic surfactant, it is not necessary to increase the particle size of the emulsion, and it is not necessary to reduce the amount of adhesion and treat it, and stable performance can be secured.
In particular, it shows good performance even for a fluorescent bleached yarn.
