Embodiment 1

[0049] Embodiment 1: produce 30g / m 2 Cotton partially water-repellent spunlace fabric

[0050] Pure cotton fiber → carding → spunlace → local water repellent finishing → drying → coiling → inspection and cutting.

[0051] The water-repellent finishing liquid is made by mixing fluoride water-repellent agent, thickener and water.

[0052] The pure cotton spunlace cloth can be straight-laid spunlace cloth, cross-laid spunlace cloth, dry cloth, or wet cloth; this test is a cross-laid 35g pure cotton dry cloth.

[0053] The weight percentages added are

[0054]

[0055] Viscosity testing shows that the viscosity of the water-repellent finishing liquid of this embodiment is 2100mpa.s.

[0056] In the batching tank, according to the order of water→fluoride→thickener→ammonia water, add in order while stirring, and adjust to the appropriate viscosity. After the water-repellent finishing solution is prepared, it is put into the roller coating solution tank, and the water-repellen...

Embodiment 2

[0082] Embodiment 2: produce 15g / m 2 Partially water-repellent SS spunbond non-woven fabric is compared with ordinary hydrophilic SS.

[0083] SS spunbonded non-woven fabric unwinding → local water repellent finishing → drying → coiling → inspection and cutting.

[0084] The water-repellent finishing liquid is made by mixing fluoride water-repellent agent, thickener, hydrophilic agent and water.

[0085] The weight percentages added are

[0086]

[0087] Viscosity testing shows that the viscosity of the water-repellent finishing liquid of this embodiment is 2800mpa.s.

[0088] In the batching tank, follow the order of water → fluoride → antistatic agent → penetrant → thickener → ammonia water (the order of adding fluoride, antistatic agent, and penetrant is not affected), add them in sequence while stirring, and adjust to the appropriate viscosity. After the water-repellent finishing liquid is prepared, it is put into the roller coating liquid tank, and the water-repell...

Embodiment 3

[0103] Embodiment 3: produce 30g / m 2 Cotton partially water-repellent spunlace fabric

[0104] Pure cotton fiber → carding → spunlace → local water repellent finishing → drying → coiling → inspection and cutting.

[0105] The water-repellent finishing liquid is made by mixing fluoride water-repellent agent, thickener and water.

[0106] Pure cotton spunlace cloth can be straight-laid spunlace cloth, crossed spunlace cloth, dry cloth, or wet cloth; this test uses 35g straight-laid pure cotton spunlace cloth wet cloth.

[0107] The weight percentages added are

[0108]

[0109] Viscosity testing shows that the viscosity of the water-repellent finishing solution of this embodiment is 2600mpa.s.

[0110] In the batching tank, according to the order of water→fluoride→thickener→ammonia water, add in order while stirring, and adjust to the appropriate viscosity. After the water-repellent finishing solution is prepared, it is put into the roller coating solution tank, and the w...

Abstract

The invention discloses water-repellent finishing liquid for partial water repellence. The water-repellent finishing liquid is prepared from the following components in percentage by mass: 0.5 to 5 percent of a water repellent agent, 80 to 95 percent of water, 1 to 5 percent of a thickening agent and 0.01 to 0.5 percent of ammonia water, wherein the mass percent concentration of the ammonia wateris 15 to 20 percent. According to the water-repellent finishing liquid provided by the invention, a use method of the water-repellent finishing liquid is changed by preparing the water repellent agentinto high viscosity (the viscosity is more than or equal to 2,000 mpa.s) from low viscosity.

Description

technical field [0001] The invention belongs to the field of nonwoven materials, and in particular relates to a water-repellent finishing liquid, a partially water-repellent fabric and a preparation method. Background technique [0002] The existing water-repellent finishing is to carry out water-repellent treatment on the whole product, such as protective clothing, umbrellas and other water-repellent treatment. [0003] The general process of water-repellent finishing non-woven fabrics: non-woven fabric → impregnation (water-repellent finishing liquid) → drying → coiling → inspection. [0004] Main features of water repellent nonwovens: [0005] Water-repellent cloth; the product has a lotus leaf effect, and when water is sprayed on the cloth surface, it will scatter in the form of water droplets and cannot infiltrate the cloth surface. The product has a wide range of applications, and has a large number of applications in medical protection, leather, clothing and other in...
