preparation example Construction

[0082] As a wax preparation method, for example, in a stirred warm water system at 90°C, add melted wax and an emulsifier, directly maintain the emulsification temperature at 90°C, and dilute to a solid concentration of 20% to obtain a wax emulsion.

[0083] The weight ratio of the surfactant to the total amount of the wax and the surfactant is 5 to 45% by weight, more preferably 8 to 40% by weight, particularly preferably 10 to 35% by weight. When the weight ratio of surfactant is less than 5 weight%, the emulsification of wax will fall and it will become difficult to obtain a uniform emulsion. On the other hand, if the weight ratio of the surfactant exceeds 45% by weight, the film becomes soft, and viscosity problems such as poor opening on the loom may occur.

[0084] As the step of adding the wax, a step of separately preparing an aqueous dispersion of wax, adding the aqueous dispersion of wax to the paste component A obtained in the above-mentioned neutralization step, an...

Embodiment

[0118] Hereinafter, the present invention will be described in detail using examples and comparative examples, but the present invention is not limited thereto. First, measurement methods of physical properties and the like shown in Examples and Comparative Examples are shown below.

[0119] (1) Weight concentration of solids

[0120] For a certain amount (generally 1.0 to 2.0 g) of a sample (weight: M1), the weight concentration of solids was measured using an infrared moisture meter (Kett Scientific Research Institute Co., Ltd., loss on drying method, FD230).

[0121] The weight concentration of solids can be calculated automatically if an infrared moisture meter is used, but the measurement principle is based on the above M1 and the weight (M2) after drying the sample with an infrared moisture meter to a constant weight (M2), using the following formula Calculate the weight concentration of solids. M2 is the weight of the solid.

[0122] Weight concentration of solids (%...

manufacture example 1-1

[0184] [Manufacture example 1-1] (manufacture of paste component A in the manual)

[0185] In a 4-neck flask (capacity 1000ml) equipped with a thermometer, a stirrer, a condenser, and a nitrogen blowing port, mix and stir a polymerizable component (the type and amount are shown in Table 1), 150 g of ion-exchanged water, and 95 g of ethanol as a solvent , 30 g of isopropyl alcohol, and 4.5 g of benzoyl peroxide as a polymerization initiator to obtain a mixture. While blowing nitrogen gas, copolymerization was carried out at 82°C for 5 hours to obtain a reaction mixture containing a copolymer.

[0186] After the copolymerization, 72 g of ammonia water with a concentration of 16% was slowly added to the reaction mixture to neutralize (pH 7 to 10) the copolymer, and cooled to room temperature to obtain a paste component liquid containing paste component 1-1 containing a neutralized product of the copolymer 1-1.

[0187] The viscosity of the aqueous solution (viscosity of the pas...

Abstract

The object of the present invention is to provide a fiber paste capable of imparting excellent adhesiveness and sticking resistance to yarns, and capable of suppressing the occurrence of smearing; a paste-attached yarn obtained by sizing the fibers with the paste; And a method for producing textiles using the paste-attached yarn. The paste for fibers of the present invention contains a copolymer obtained by copolymerizing a polymerizable component containing (meth)acrylic acid, an alkyl (meth)acrylate-based monomer, and a styrene-based monomer, and / or a neutralized product thereof , wax, and water as essential components, and the surface tension of the aqueous solution after adjusting the weight concentration of solids contained in the paste to 12% is 30 to 60 mN / m.

Description

technical field [0001] The present invention relates to fiber paste and its application. More specifically, the present invention relates to a warp paste particularly preferably used in weaving, a paste-attached yarn obtained by sizing the paste, and a method for producing a textile using the paste-attached yarn. Background technique [0002] Various properties such as adhesive force, water resistance, abrasion resistance, sticking resistance, and scouring properties are required for pastes used for weaving fibers. Moreover, when weaving using a filament yarn, in order to improve the production efficiency, weaving is performed using a loom (for example, patent document 1). [0003] In addition, recently, the denier of the warp is gradually reduced (fine denier). Compared with ordinary denier, yarn with small denier is easy to cause warp breakage during weaving because the yarn is thin and weak. In general, in order to prevent warp breakage during weaving, the amount of st...
