Problems solved by technology

Research on this technology began in the 1970s and 1980s, but so far this technology has not been well applied
The key is that the foam is a metastable system. After the foam is produced, if it cannot be used immediately, the foam will expand, merge and rupture over time, which will lead to unevenness of the size applied to the yarn. and inconsistency, resulting in the inability to stabilize production

Embodiment 1

[0045] Take pure cotton CF50 / 1 colored yarn as an example;

[0046] The traditional sizing process is as follows: the warp yarn is dried by a drying cylinder to remove moisture from the yarn and then enters a high temperature storage tank. The yarn passes through the rollers in the storage tank to complete the sizing process, and finally the yarn is dried by the drying cylinder. Sizing process.

[0047] The specific steps of this embodiment 1 are as follows:

[0048] (1) Configure slurry

[0049] 1000g of water;

[0050] Modified starch DM816344g (purchased from Dongmei Company);

[0051] 64g SD propylene slurry (purchased from Sunda Chemical);

[0052] Polyvinyl alcohol (PVA) 35g;

[0053] Wax oil SFO-3016g (purchased from Yixing Junda);

[0054] Antistatic agent TS-656g (purchased from Shanghai Xida);

[0055] Foaming agent FO40005g (purchased from Rudolf Chemical).

[0056] (2) Boiling pulp

[0057] Control the slurry temperature to 80°C.

[0058] (3) Foaming

[0059] The foam generator is u...

Embodiment 2

[0073] Taking pure cotton CF40s / 1 colored yarn as an example, the traditional sizing method can be seen in Example 1:

[0074] The warp sizing method of this embodiment is: combining figure 1 , The warp yarn is drawn out from the warp beam, and after passing through the guide roller 1, it is ready for sizing; put the prepared slurry in the slurry tank 2, and the slurry is fed into the slurry tube 8 through the foam generator 7 to form foam. The output tube 9 outputs, and then through the output tube 10 of the lower foam applicator and the output tube 11 of the upper foam applicator respectively, the foam is transported to the lower applicator 3 and the upper applicator 4 of the foam applicator, so that the foam slurry flows from the upper and lower two The direction is applied to the yarn, and then through the pressure of the roller 5, the slurry foam is burst and penetrates into the yarn and fiber. The yarn squeezed by the roller 5 is passed through the guide roller 1 and then ...

Embodiment 3

[0102] Take pure cotton JC40s / 1 colored yarn as an example, the traditional sizing method can refer to Example 1;

[0103] The specific steps of this embodiment 3 are as follows:

[0104] (1) Configure slurry

[0105] Water 1000g

[0106] Modified starch DM816344g (purchased from Dongmei Company);

[0107] 57g SD propylene slurry (purchased from Sunda Chemical);

[0108] Polyvinyl alcohol (PVA) 33g;

[0109] Wax oil SFO-3014g (purchased from Yixing Junda);

[0110] Antistatic agent TS-654g (purchased from Shanghai Xida);

[0111] Amphoteric foaming agent RR20g (purchased from Ningbo Bosite).

[0112] (2) Boiling pulp

[0113] Control the slurry temperature to 85°C.

[0114] (3) Foaming

[0115] The foam generator is used to foam the already configured slurry system. The foaming ratio and application amount can be accurately controlled by the computer control system of the equipment. The foaming ratio is controlled to be 1:3 and the application amount is 40%.

[0116] (4) Foam sizing

Abstract

The invention discloses a warp sizing method and an application thereof. The warp sizing method includes the following steps: preparing sizing agents, boiling the sizing agents, foaming, conducting foam sizing, rolling the sizing agents, drying and leasing; foaming ratio and applying amount are controlled by a foam producer in the step of foaming; the foaming ratio is 1:3-30, and the applying amount is 10%-50%; foam formed by the foam producer is instantly and entirely applied to warp yarn through a foam applicator in the step of conducting foam sizing; and the foam applicator is divided into an upper applying head and a lower applying head. The warp sizing method has the advantages of being low in water consumption, little in chemical and wastewater discharge, little in sizing amount, easy to desize, short in yarn drying time, capable of saving energy consumption by 50%-60%, high in production speed, low in cost, continuous in foam applying mode, capable of ensuring uniformity and stability of the applied foam, low in product breakage rate, high in efficiency and good in weaving effect.

Description

Technical field [0001] The invention relates to the technical field of textile dyeing and finishing, in particular to a warp sizing method and its application. Background technique [0002] As we all know, the warp yarn needs to be sizing before the yarn is woven. The purpose of warp sizing is to lay down the hairiness, improve abrasion resistance, ensure that the warp has a certain strength and elasticity, and reduce the rate of breakage during weaving. The traditional warp sizing process is as follows: the warp is first dried by a drying cylinder to remove the moisture content of the yarn, then enters the high-temperature size tank, and is squeezed by the roller. On the one hand, the size is penetrated into the yarn and fiber, and the roller is used on the other The pressure makes the excess size squeeze out, and finally the yarn is dried by the drying cylinder to complete the sizing process. Generally speaking, the traditional padding sizing method uses water as a medium to ...
