Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an oil composition for synthetic fibers, and more particularly to an oil composition for synthetic fibers that imparts stain resistance during the spinning process of synthetic fibers.

Conventionally, synthetic fibers with good mechanical properties have been widely used in interior products such as carpets, curtains, and upholstery. However, these Inchirya products are often used in daily life at home or in places where a large number of unspecified people gather, and they can become contaminated by spilling food and drinks such as coffee, cola, milk, juice, and even sauce. many. For this reason, recent attempts have been made to obtain stain-resistant products by post-processing stain-repellent finishing agents on Inchiriya products by spraying or the like, and then heat-treating the heels to give them complete water and oil repellency. This water- and oil-repellent coating, such as carpet, does not soak into the fiber assembly immediately even if coffee is spilled on it, so if you wipe it off immediately, the dirt will not stain easily. 0 However, when imparting such water and oil repellency to Inchiriya products through post-processing, the number of steps increases due to the addition of a rear dyeing process to the normal dyeing process, reducing productivity. Many of the products such as chair upholstery 9 are made with raised hair, and when they are post-processed using the spray method, only the tip of the raised hair is attached, and the inside is not modified. It is difficult to remove the dirt that has entered, and it has the drawback of causing stains. Further, post-processing using the pad method has drawbacks such as the naps falling down and the drying requiring time and energy.

The present inventors have conducted intensive research on a method of applying a water and oil repellent along with an oil agent during the production of synthetic fibers to provide a durable and effective antifouling effect, and as a result, have developed the entire oil composition of the present invention. . Specifically, the present invention provides a fluorine-based oil repellent having at least one fluorine-based oil repellent in the base molecule that can react with an isocyanate group,

This is an oil composition for synthetic fibers, which is characterized by:

The compound varies depending on the target synthetic fiber and the stretching method, but it is usually 90% when applied before stretching polyester fiber or polyamide fiber and stretching in a water bath.
Particularly preferred are metal compounds that are activated at a temperature of 120 to 180°C or higher and regenerate NCO groups. In such a case, if the activation is too high, not only the workability of the scum metal during the drawing process will be lowered, but also the durability will be lowered.

The role of each component in the composition in the present invention is to coat the surface, fix it to the fibers, and provide a durable antifouling effect. The ester smoothing agent Ω acts as a lubricant or smoothing agent to maintain productivity in the spinning and drawing process, and also provides operability and wear resistance in subsequent steps. Furthermore, when applied to fibers immediately after spinning, ester-based smoothing agents have a swelling effect on the fibers, which improves the penetration of components (A) and (B) into the fibers or the adhesion with the fibers, thereby improving durability. It also has the effect of improving. Of course, it must not inhibit the antifouling effect of component (5). Next, (to)
Ingredients and component
It has the role of preventing static electricity generation and providing focusing properties.

The blending ratio of each of the above components is (5) component 100 in weight ratio.
B) component 5 to 30 parts, preferably 8 to 15 parts, (0 component 5 to 40 parts, preferably 10 to 30 parts, B) component 5 to 50 parts, preferably 1-1!: It is 10 to 40 parts.

The oil composition of the present invention is usually used in water, but
Add a fluorine-containing surfactant to the aqueous dispersion at o, ooi ~ 0.1
It is particularly preferable to use them in a combined amount of 0.005 to 0.05% by weight. The amount of component (5) applied to the fibers is usually 0.03 to 1% by weight, preferably 0.05 to 0.3% by weight. Therefore, the total active ingredient is usually diluted to θ, 1 to 30% by weight, preferably 0.2 to 10% by weight.

If the applied amount is less than 0.03% by weight, the effect and durability will be insufficient, and if it exceeds 1% by weight, the runnability of the yarn, crimpability, and the obtained stability in the spinning and drawing process will be poor.

- This results in the drawback that the spinnability of the pull fiber is impaired. Furthermore, if the amount of component (J3) is too small, the durability of component (G) will be insufficient, and if it is too large, the resulting film will become too hard, and fibers will adhere to each other.

In addition, (if the Q component is too small, the running properties of the yarn will deteriorate,
If the amount is too high, the durability of component (4) decreases, resulting in a decrease in water and oil repellency after dyeing. This is thought to be because (C'1 component inhibits the film properties of the captive component and exhibits a mold release effect. (To) + (2) If the component is too small, the emulsion stability, thread cohesiveness, and static electricity The preventive property deteriorates, and if the amount is too large, the water and oil repellency decreases, and the coefficient of dynamic friction of the thread increases.It is preferable that the component (■) is 50% by weight or less relative to the 0+container component. g) If it is mainly composed of ingredients, there will be a drawback that water and oil repellency and, in some cases, liquid stability will be impaired.

The oil composition of the present invention may further include oil agents such as mineral oil, polypropylene glycol, and polypropylene glycol ether, and hydrophilic and antifouling treatments such as polyester polyether block copolymers and polyamide polyether block copolymers. It is also possible to use various processing agents having affinity or diffusivity for fibers, such as fungicides, ultraviolet absorbers, dyes, etc.

The present invention will be explained below with reference to Examples. Incidentally, ``chi'' in the examples is based on weight. In addition, the water repellency and oil repellency were evaluated using the following method using fabrics produced using treated synthetic fiber yarns.

l) Water-repellent A solution was prepared by mixing isopropanol and water at a certain ratio, a small drop of this solution was placed on the surface of the fabric, and the entire wetness was observed.

A cut fiber was obtained. After dyeing this fiber using a conventional method, a needle bunch carpet was prepared and the water and oil repellency was evaluated. ) alone was added at 0.15% to the fiber.

The oil composition of the present invention provided a polyester stable with excellent thread-spinning properties, water and oil repellency, and high durability.

Example 2 The same oil dispersion as in Table 1 Sample 1 was used as the spinning oil and drawing bath, and for the tow of nylon 6 fibers, the
After applying 17 fibers, stretching, heat setting, and crimping, the fibers were cut to obtain a cut fiber of 8d-128wa. The fibers are dyed in a conventional manner, made into a spun yarn, and the pile is cut into a P base fabric using a tact machine to produce a cut pile carpet. After lining, the finished shearing process is performed to produce a pile of approximately 10 A simple cut pile carpet (velor style) was obtained.

The resulting carpet had a water repellency of 4th grade and an oil repellency of 3rd grade. Furthermore, even if coffee at 60°C was poured on the carpet, it could be easily removed by wiping it off without passing underneath.
