Embodiment 1

[0039] A kind of processing technology of waterproof yarn, with reference to attached figure 1 shown, including the following steps:

[0040] Step 1: Add 1Kg degreaser and 500g caustic soda to 1m 3 Mix in clear water at a speed of 500rpm to obtain a degreasing liquid;

[0041] Step 2: Heat the degreasing liquid to 90°C, soak the yarn into the degreasing liquid, and keep it warm for 30 minutes;

[0042] Step 3: Use an acetic acid solution with a concentration of 0.2 g / L to neutralize and wash the degreased yarn for 5 minutes, and then wash it with water for 3 minutes;

[0043] Step 4: put the yarn into the dyeing vat, and add 55% clear water of the volume of the dyeing vat, add the leveling agent GS and the dye HFRL violet at a ratio of 1:2 to the dyeing vat in turn, to obtain a dyeing solution with a concentration of 5 wt% of the dye HFRL violet, Dyeing is carried out in sequence (①heat up to 80°C at 1.5°C / min; ②raise to 135°C at 1.2°C / min and keep warm for 40 minutes; ③dir...

Embodiment 6

[0061] The difference between this example and Example 5 is that the starch of the present application is soaked in 3% hydrogen peroxide for 1 hour to obtain oxidized starch.

Embodiment 7

[0063] The difference between the present embodiment and the fifth embodiment is only that the cyanuric chloride of the present application is modified by palmityl secondary amine.

[0064] The concrete steps are as follows: the first step: mix 0.1mol cyanuric chloride, 0.5mol anhydrous K 2 CO 3 , 0.25mol of palmityl secondary amines were added successively in a 250mL three-necked flask, protected by nitrogen, left to stand for 0.5h under an ice-water bath, injected with 200mL of dry THF and dry dioxane [V(THF):V(dioxane)= 1:4], reacted in an ice-water bath and at room temperature for 4 h respectively, and then refluxed the reaction, removed the solvent under reduced pressure, washed with water until neutral, and separated by column chromatography [eluent: V (ethyl acetate): V (petroleum ether)=1:200], to obtain a white solid powder;

[0065] The second step: 0.5mol anhydrous K 2 CO 3 , 50mL 1,6-hexamethylenediamine and 150mL dioxane were sequentially added to the white so...

Abstract

The invention discloses a waterproof yarn processing technology, and relates to the spinning field. The waterproof yarn processing technology mainly comprises the following steps that firstly, an oilremoval agent and caustic soda are added in water, temperature is raised to 90 DEG C for sufficient mixing, and oil removal liquid is obtained; secondly, yarn is wetted in the oil removal liquid for oil removal; thirdly, an acetic acid solution is utilized for conducting neutral cleaning on the yarn obtained after oil removal, and then washing with water is conducted; fourthly, the yarn washed bywater is dyed, and then cleaning is conducted; fifthly, the cleaned yarn is wetted in waterproof liquid to be subjected to waterproof treatment; and sixthly, the yarn obtained after waterproof treatment is thoroughly cleaned, shading and shadow airing are conducted, then, drying is conducted, and finished waterproof yarn is obtained. Firstly, oil removal treatment is conducted on the yarn so thatyarn surface cleanliness can be guaranteed, accordingly, the later dyeing and waterproof treatment quality can be better improved, and color fastness and waterproof performance of the yarn are guaranteed.

Description

technical field [0001] The invention relates to the field of textile field, in particular to a processing technology of waterproof yarn. Background technique [0002] Yarn is a product processed from various spinning fibers into a certain fineness, which is used for gauze, rope making, thread making, knitting and embroidery, etc. Moreover, the yarn is usually white when it comes out of the yarn machine, but it can also be dyed as desired for use in clothing, bedding or other decorative items. [0003] For those outdoor sports enthusiasts who work in the office on weekdays, they can only go to parks or woods to participate in certain outdoor sports in the morning and evening. However, due to the generally low outdoor temperature in these two time periods, especially in winter, frost and dew are more likely to appear in the morning and evening. At this time, if outdoor sports enthusiasts wear knitted clothing or hats to keep warm, since the water contact angle on the surface...
