Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a spray-type fiber sizing agent, more specifically, used for finishing clothes after washing.

This invention relates to a spray-type glue with extremely excellent performance.

In recent years, in general households, after washing shirts, etc.
Spray-type fiber sizing agents are commercially available that are used to apply a sizing finish by spraying with a pump spray, an aerosol spray, or the like.

These glues are required to have various properties depending on their purpose, but in particular the following properties are required: (1) The surface of the fabric treated with the glue has a beautiful appearance (2)
Excellent ironing slippage after starch treatment (3) Excellent bending hardness of cloth treated with starch (4) Excellent spray mist and spray pattern (5) Starch It is required that there is little foaming on the fabric surface when processing with.

However, conventional spray-type fiber glues use polysaccharide derivatives such as starch derivatives or polyvinyl alcohol (hereinafter referred to as PvA) alone as the glue component, and further add other ingredients to satisfy these properties. It is manufactured by combining.

However, in those using polysaccharide derivatives, the above (2),
Although the performance of (4) and (5) is good, the size precipitates white on the surface of the treated cloth (cloudy appearance), the color of colored cloth appears faded, and the concentration of the size increases. Therefore, the "bending hardness" fluctuates, and its adjustment is difficult, resulting in insufficient performance in terms of (1) and (3) above.

On the other hand, those using PVA are based on the above (1) and (3).
Although the performance of items (5) to (5) is good, the iron slippage after treatment is poor and the starch adheres to the iron, and the performance is not sufficient in terms of (2) above.In view of these circumstances, the present inventors , (1) to (
In order to obtain an excellent spray-type fiber glue that satisfies all of the properties listed in 5), we first investigated the idea that by using a polysaccharide derivative and PVA together, the two would compensate for each other's shortcomings. Although the performances of (2) to (5) above are good,
It was found that "glue fogging" still occurred and the performance was not sufficient in respect of the above (1).

Therefore, as a result of further investigation, we found that all of the above performances (1) to (5) were satisfied by using these in combination with lower alkyl acrylate, vinyl acetate, or an emulsion of a copolymer of styrene and vinylpyrrolidone. In addition, it was discovered that a spray-type fiber sizing agent that gives a finish with excellent texture could be obtained, and the present invention was completed.

That is, the present invention provides a spray-type fiber glue containing three essential components: a specific polysaccharide derivative, PVA, and a copolymer emulsion of vinyl pyrrolidone and lower alkyl acrylate, vinyl acetate, or styrene. The glue of the present invention has no problems with "glue fog" or iron slippage, has a good finish hardness and texture, and has extremely excellent performance.

The polysaccharide derivative used is a starch derivative such as etherified starch or esterified starch, preferably with a degree of etherification of 0.1.
(1 etherified starch per 1000 glucose) or pullulan with a molecular weight of 200,000 or less (
Polymer substances in which maltotriose is polymerized in large numbers through α-1,6 bonds).

PVA has a saponification degree of 80 or more and a polymerization degree of 1700.
Preferably, the number is 1700 to 300.

Also, vinylpyrrolidone and lower alkyl acrylate,
Examples of copolymer emulsions with vinyl acetate or styrene include copolymers of lower alkyl acrylates such as methyl acrylate and ethyl acrylate and vinylpyrrolidone, copolymers of vinyl acetate and vinylpyrrolidone, or copolymers of styrene and vinylpyrrolidone. An aqueous emulsion in which particles with a particle size of 0.5 μ or less account for 95 or more of the total particles, such as commercially available Antara 430 (General Anilin).
40 hydrophilic emulsion of styrene-vinylpyrrolidone copolymer manufactured by E&Film Corporation.

From the viewpoint of the performance of the sizing agent, these three components should be blended in 3 to 10 parts in the final product as a whole, and
In the total amount of components, PVA and the copolymer emulsion are
It is preferable that each of them is blended so that it accounts for 10% or more.

The spray type fiber sizing agent of the present invention can be formulated into a pump spray type or an aerosol spray type according to conventional methods.

Other ingredients include ingredients that are included in regular spray-type textile glues, such as various surfactants, antifoaming agents, texture improvers, preservatives, antifungal agents, fragrances, and propellants (for aerosol sprays). case), etc.

In particular, in the pump spray type glue of the present invention, (1) 0.5 to 2.0 to stabilize the emulsion of fragrances and preservatives;
Phosphate tristearate (2) 0.05 to 0 to improve the finish of the cloth surface,
3% (7) Release silicone (as a 35% emulsion) (3) Defoaming silicone of 0.01 to 5 modulus (as a 19% emulsion) (4) PVA plasticizer, texture improver, iron slip 0.1 to 5.0% polyethylene glycol (with a molecular weight of 300 to 1500), ethylene glycol, glycerin (5) to improve flavoring, and 0.5 to 20% ethanol to dissolve preservatives. It is preferable to mix them.

In addition, in the aerosol spray type glue of the present invention, (1) antifoaming silicone (19%
