Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to powdered and liquid laundry size compositions for domestic use, and more particularly, the present invention relates to powdered and liquid laundry size compositions for household use, and more specifically, sizing can be applied to objects to be treated even under conditions where the bath ratio is large. Wash +6 with excellent tensile strength! Conventionally used laundry starches for starch compositions are made by dissolving the starch in a small amount of water when gluing.
Gluing is done by rubbing it evenly into the kimono. However, if the amount of water is too small, the gluing will not be done evenly. Therefore, it is preferable to use enough water to apply the paste evenly, but most of the glue used will be thrown away along with the drainage, and it is also important to use sufficient water. In addition, conventionally used laundry glues include those containing a%) as the main ingredient, those containing natural polymer derivatives such as carboxyl methylcellulose, and those containing polyvinyl alcohol and vinyl acetate. There are products that are made from synthetic polymers such as polymers, and their lie-shaped beads can be in powder or liquid form.

Glue 4J, whose main component is starch, is used in the form of pregelatinized powder or glue paste, and is widely used because it is cheaper than natural polymers or synthetic Hata molecules. ing. However, the finish is too hard, and in liquid form, problems such as α-starch deteriorating to β-starch, rotting, and mold formation occur.

Here, α-starch refers to a gelatinized state, and is a name that corresponds to β-starch, which is a natural (raw material).

In order to solve such drawbacks, the present inventors have diligently researched 11) binding, and when cationic starch is used as a laundry glue,
Even at a large bath ratio, it has good finger absorption on clothing and provides good tensile strength 1 (without waste).

Also, compared to raw starch, cationized starch has a much better stability of the size liquid, so α-starch does not change to β-starch and does not cause spoilage or mold formation. They also discovered that the film formed on the surface of the glued clothing had a certain degree of rigidity and elasticity, and were able to complete the main room.

The cationization of the cationic starch is described by Mazubetsu, LTF
&, corn, tapioca, wheat and other starches, halogenated alkyl ammonium salts, halogenated alkyl 3
(2t,t,z&)alkylamine 1 halogen ratio alkyldiamine, epoxidized alkyl & quaternary alkyl ammonium salt, epoxyalkyl 3
In addition to directly reacting with cation modifiers such as secondary (secondary, primary) amines, aminoethyl sulfate, ethyleneimine, sulfonium, cyanamide, alkali metal cyanamide, alkaline earth cyanamide, etc., alkylamines can be reacted with epichlorohydrin and then treated with alkyl amines. Examples include those in which acrylamide is subjected to ether bonding and then subjected to Hofmann decomposition or Mannich reaction, and those in which (meth)acrylonitrile is added and then hydrogenated. The degree of cationization is expressed as the degree of substitution [6-IAD, S, mol) D per mole of glucose residue.

4.=0.01 to 0.3 cations may be introduced.

In addition, when carrying out the present invention, the cationic starch may be used as a powdered pregelatinized cationic starch that has been pregelatinized at a high temperature, or in advance at a concentration of 10 to 15% 1
It is used as a powdered cationic starch that has been gelatinized at one time.

In the present invention, pregelatinization is performed using cations 4 + 6
On the other hand, one or more types of soap, charcoal wax, blue acid sacrificial bowl, and soda carbonate, bicarbonate soda, sesquicarbonate soda, pyrroline + Vi sorta, tripolyphosphate sodium, orthophosphorus soda, and tetraphosphate soda. Add 0.1 to 1 hA% of one or more of Alka II 11 E having a soda salt such as 2° to 60-11+t%,
Note: 35 to 45% Q) Make 1 liquid of water, add a few molecules (L) at 90-150°C, and add several tens of minutes to 1tt.
＋, a general method of drying and pulverizing using a drum dryer, belt dryer, etc.) is used.

Further, gelatinization of the cationic starch can be carried out using the usual Tsuku-Sochi-style starch boiling method, or a general method using a continuous type onlator or a jet cooker.

The laundry starch composition of the present invention has a cationic property (
By blending natural (removed wood) starch with starch, -f I lehua-
It may also be made into a powder or a liquid by gelatinization and gelatinization, respectively.

Next, the present invention will be explained using a practical example.

Example 1 100 parts of cornstarch was added to 125 parts of water, 2.2 parts of sodium hydroxide, and 50 parts of sodium sulfate, and then 5 parts of β-soethylaminoethyl chloride was added to the mixture at 45°C. After reacting for 5 hours, the concentration was reduced to H4.5 with dilute hydrochloric acid, dehydrated, washed with water, and dried.

It is a tertiary cationized starch with S, ) = 0.04.

Example 2 100 parts of #1 potato powder was added to a solution of 125 parts of water, 1.8 parts of hydroxide, and 50 parts of sodium sulfate.
IL and then 3-chloro-2-hydroxopropyltrimethylammonium chloride After reacting at °C for 8 hours, the pH was lowered to 4.5 with dilute hydrochloric acid, dehydrated, washed with water, and dried. The obtained 1# mask is hyaloquinepropyltrimethylammonium substituted ant (D.
S. ) = 0.0 4 quaternary cationized starch.

Example 3 Examples 1 and 2 and commercially available boiled paste (part name: Mizuku paste), polyvinyl alcohol (product name: PO/BOL), polyvinyl acetate emulsion (part name: Keeping), cationic vinegar biemul soyon ( The following gluing tests were conducted using parts name: New Keeping) and fluorescent parts (product name: Keiko Glue).

For gluing, make a 1mm liquid of each size with ion-exchanged water so that the test solid content concentration is 0.4%, and add each type of cloth to this 200cc liquid at the bath ratio. (i.e. 2.86 g) at about the first 30 f. After that, after dehydration with 30 paper dehydration 2, air dry, iron press (130'C x 1 minute),
Tension hardness was measured by the Kansen lever method according to IS-1005-1959. At the same time 20'C, 65%R
Store IEJ in the constant temperature and humidity room of
Im was measured and the adhesion rate was measured. The results are shown in Table-1.

As is clear from k-1, it can be seen that the cationic starch paste of the present invention is superior to both the starch paste of the present invention and the synthetic commercial molecular type starch paste in terms of adsorption and tensile strength.

Example 4 Each size insert composition used in Example 3 was tested for adhesive fogging and long-term storage stability.

Adhesive fogging test 11: After applying each lubricating agent evenly to colored polyester fibers, the fogging property was checked.
It took a while.

○ No fogging is observed in the light.

△ Slight 1' fog is observed.

× I suspect it's quite a 1' cover.

Storage stability After each adhesive composition was left at 25'C for 2 months, the state of separation was visually determined.

Raw (Tsugai++'j) There is no change, and the separation has not stopped.

△　External has changed or no separation has occurred.

× Separated.

The results are shown in Table-2.

Table 2 From Table 2, it can be seen that -91 to D) shows that Mt. Mt. Mt. L117's blade 1 hu has a paste cover and a long N1 holder's game is defeated.
