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 the dryer to remove the moisture content of the yarn and then enters the high-temperature size storage tank. The yarn is squeezed by the rollers in the size storage tank to complete the sizing process, and finally the yarn is dried by the dryer to complete the process. Sizing process.

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

[0048] (1) Configure slurry

[0049] Water 1000g;

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

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

[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) boiled pulp

[0057] Control the slurry temperature t...

Embodiment 2

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

[0074] The warp yarn sizing method of the present embodiment is: combine figure 1 , the warp yarn is drawn out from the warp beam, and after the guide roller 1, it is ready for sizing; the prepared slurry is placed in the slurry barrel 2, and the slurry is formed by the slurry input pipe 8 through the foam generator 7. Foam is formed by the foam The output pipe 9 is output, and then the foam is transported to the lower application head 3 and the upper application head 4 of the foam applicator through the foam lower application head output pipe 10 and the foam upper application head output pipe 11, so that the foam slurry can flow from the top to the bottom The direction is applied to the yarn, and then through the pressure of the roller 5, the slurry foam is broken and penetrated into the yarn and fiber. The yarn squeezed by the roller 5 is wound around the gu...

Embodiment 3

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

[0103] The concrete steps of present embodiment 3 are as follows:

[0104] (1) Configure slurry

[0105] water 1000g

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

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

[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 Busset).

[0112] (2) boiled pulp

[0113] The slurry temperature was controlled to be 85°C.

[0114] (3) Foaming

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

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 yarn sizing method and its application. Background technique [0002] It is well known that warp yarns need to be sized before yarns are weaved. The purpose of warp yarn sizing is to fit hairiness, improve wear resistance, ensure warp yarn has a certain strength and elasticity, and reduce the end-break rate during weaving. The traditional warp yarn sizing process is as follows: the warp yarn is first dried by the dryer to remove the moisture content of the yarn, then enters the high-temperature size tank, and is squeezed by rolls. On the one hand, the size is penetrated into the yarn and fiber, and on the other hand, the roll 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 the medium to dissolve ...
