Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a good warp sizing method in which a mixed glue solution of an acrylic glue agent and a wax emulsion is applied in the fabric preparation process for synthetic filament yarns and synthetic spun yarns, and the subsequent drying process is omitted. It is related to.

To describe the purpose of the invention in more detail, a roller sizing machine, a beam sizing machine, a warper sizing machine, etc. However, in both cases, the glue is adjusted, the glue is applied by soaking it in the glue or by rotating a roller, and the moisture is evaporated using a drying chamber or hot air to create a thread. These warp yarns were used to weave by running them on innovative looms such as water jet looms or air jet looms.However, this conventional method requires a huge amount of energy in the drying process.

A sizing method that does not require drying has been eagerly awaited.

To meet these demands, glue is applied by dissolving a glue agent in an organic solvent. So-called dry sizing, or a method of weaving with only wax emulsion attached to the thread (Patent No. 828910f), mineral oil,
Composition consisting of thread of fatty acid ester, nonionic activator, phosphoric acid triester or phosphorous acid triester, and diorganopolysiloxane (JP-A-52-137096'
Methods such as attaching with a wever using I have been carried out mainly by relying on the smoothness of the oil.

The dry sizing method dries a little faster than the conventional sizing method, but it does not require a drying process at all, and the drying capacity can be reduced slightly compared to the conventional sizing method. It is not good because the solvent is emitted into the working environment, and since an expensive organic solvent is used as the solvent, it does not make any significant contribution to the economic efficiency of the original purpose. In addition, as for the method relying on the smoothness of the oil agent, even if the smoothness is improved, sufficient convergence cannot be obtained and the original purpose cannot be achieved.

Therefore, the inventor of the present invention has conducted repeated research to find a sizing method that can omit the drying process, which requires a huge amount of energy, and also simplify the process.

First, the acrylic adhesive used in conventional sizing was dissolved in water and sized using a direct weaver, and the drying process was omitted and the yarn was wound onto a beam for weaving. It was found that a blocking phenomenon occurred and weaving was not possible. This is because it is thought that the adhesiveness is a phenomenon that occurs due to poor yarn separation between the yarns and the yarn system, so the adhesive agent consists of mineral oil, fatty acid ester, higher alcohol, and nonionic activator. As a result of using a so-called known oiling agent in combination with the above acrylic adhesive and applying it to the weaving process, the oiling agent softened the glue film, causing boiled gum up on the reed and belt, which caused clogging of the reed. It was not possible to produce and weave.

Subsequently, an emulsion made by emulsifying a wax with a melting point of 50 to 100° C. in an acrylic glue agent is mixed with the acrylic glue agent, and similarly applied with a direct warper and wound onto a beam without a drying process.

After beaming, weaving was carried out in a water jet loom, and it was found that there was no blocking phenomenon between the yarn and the system within the beam, and the drawing operation was good, and the weaving efficiency was similar to that of a bale group.Further research was conducted. As a result, the present invention was completed.

That is, 9. The present invention is characterized in that the synthetic filament yarn and the synthetic spun yarn are processed before and after twisting in the weaving preparation process, in the corning process, in the warping process, in the repeating process, and in a sizer without any drying process. J/l/acid ester.

W% (solid content) preferably.

The present invention provides a warp sizing method characterized by applying a mixed glue liquid containing 50 to 25 W% (solid content) and omitting a drying step.

Examples of the above-mentioned acrylic ester and methacrylic ester copolymers include acrylic ester/I/ and methacrylic ester copolymer adhesives.

It is an ammonium salt of a copolymer of an acrylic ester of an aliphatic alcohol having 1 to 18 carbon atoms and/or a methacrylic ester of an aliphatic alcohol having 1 to 18 carbon atoms, and acrylic acid and/or methacrylic acid.

That is, examples of acrylic esters of aliphatic alcohols having 1 to 18 carbon atoms include methyl, ethyl, propyl, isopropyl, and n-butyl.

There are esters of alcohols such as isobutyl, cetyl, stearyl, oleyl, and β-ethoxyethyl. Examples of methacrylic acid esters of aliphatic alcohols having 1 to 18 carbon atoms include methylethyl, propyl, isopropyl, normal butyl, isobutyl, tert-butyl, hexyloctyl, 2-ethylhexyl, lauryl, cetyl, stearyl, and oleyl. and esters of alcohols such as β-ethoxyethyl.

The above-mentioned acrylic esters and methacrylic esters are polymerized by polymerizing one or more of them with tyrene or the like in an alcohol solvent or a hot medium with water, and then neutralizing it with aqueous ammonia. Manufacture the agent.

As a wax emulsion, for example, melting point 50-1
00°C, esters of fatty acids with 14 to 28 carbon atoms and mono- to tetrahydric alcohols, fermented polyethylene wax, oxidized wax, natural waxes with melting points of 50 to 100°C include carbana wax, candelilla wax, beeswax, There are white wax, monk's wax, and wax wax, and these waxes are manufactured by emulsifying them alone or in a mixture with a nonionic activator, an anionic activator, either alone or in a mixture.

The above wax emulsion and the above acrylic glue are mixed in a predetermined ratio to form a mixed glue liquid.

Untwisted and twisted synthetic filament yarns and synthetic spun yarns (5
0 to '700 T/M), the total force (m) attaches to the bobbin thread.

The attachment method is 1. For example, the raw yarn is run at a yarn speed of 100 to 400771/'' with a high-speed warper, and the yarn is attached just before being wound onto the beam, and the yarn is wound and beamed without drying, and the yarn is threaded through the twill. and weave.

The process can be classified as thorny.

(a) Raw thread - one twist thread with glue → beaming - twilling → warp threading → weaving (b) Raw thread - twisted thread - with glue - beaming - one warp threading with twill → weaving (c) raw thread → temporary twist → / pasting → Corning - Beaming - Twilling, one warp, one weaving (d) Raw thread - Twisting = one repeat for gluing - Beaming - one thread for twilling, one weaving (e) Raw yarn → warper sizing → beaming → one thread for twilling, one thread for weaving In this case, the ratio of the acrylic adhesive and wax emulsion is such that the solid content of the acrylic adhesive alone or as a mixture is 25 to 75 W%.

It is appropriate for the wax emulsion to have a solid content of 75 to 25 W%, and if the acrylic glue is greater than this ratio and it is wound onto a beam without drying, a blocking phenomenon will occur between the threads and the weaving process. Therefore, the purpose of the present application cannot be achieved.

If the ratio is less than this, the blocking phenomenon between the threads and the system within the beam will not occur, but the convergence will be insufficient and &! ! a
Sex is not good.

In the present invention, good performance can be obtained by combining the binding property of the acrylic glue agent and the thread-unraveling property of the wax emulsion. The above ratio is preferably 7, > w%, and the solid content of the wax emulsion is preferably in the range of 50 to 25 W% to improve weavability.Next, in order to clarify the effects of the present invention, a comparison with the conventional method was Make a comparison.
