Examples
Embodiment 1
[0054] Embodiment 1: produce 30g / m 2 Cotton partially water-repellent spunlace fabric
[0055] Pure cotton fiber → carding → spunlace → local water repellent finishing → drying → coiling → inspection and cutting.
[0056] The water-repellent finishing liquid is made by mixing fluoride water-repellent agent, thickener and water.
[0057] 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.
[0058] The weight percentages added are
[0059] Fluoride water repellent FC3410 (Guangzhou Huayu Chemical Co., Ltd.) 3%;
[0060] Water 93.9%;
[0061] Thickener PTF (Huntsman Chemical) 3%;
[0062] Concentration 18.58wt% ammoniacal liquor 0.1%.
[0063] Viscosity testing shows that the viscosity of the water-repellent finishing liquid of this embodiment is 2100mpa.s.
[0064] In the batching tank, according to the order of water→fluoride→thickener→ammonia water, add...
Embodiment 2
[0089] Embodiment 2: produce 15g / m 2 Partially water-repellent SS spunbond non-woven fabric is compared with ordinary hydrophilic SS.
[0090] SS spunbonded non-woven fabric unwinding → local water repellent finishing → drying → coiling → inspection and cutting.
[0091] The water-repellent finishing liquid is made by mixing fluoride water-repellent agent, thickener, hydrophilic agent and water.
[0092] The weight percentages added are
[0093] Fluoride water repellent E600 (Japan Asahi Glass Chemicals) 1.5%;
[0094] Water 93.4%;
[0095] Antistatic agent TY (American Stepan Chemical) 0.2%;
[0096] Penetrant JFC (Guangzhou New Huahong Chemical) 1.5%;
[0097] Thickener PTF 3.5%;
[0098] 0.2% ammonia water with a concentration of 18.58%;
[0099] Viscosity testing shows that the viscosity of the water-repellent finishing liquid of this embodiment is 2800mpa.s.
[0100] In the batching tank, follow the order of water→fluoride→antistatic agent→penetrating agent→thicke...
Embodiment 3
[0115] Embodiment 3: produce 30g / m 2 Cotton partially water-repellent spunlace fabric
[0116] Pure cotton fiber → carding → spunlace → local water repellent finishing → drying → coiling → inspection and cutting.
[0117] The water-repellent finishing liquid is made by mixing fluoride water-repellent agent, thickener and water.
[0118] 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.
[0119] The weight percentages added are
[0120] Fluoride water repellent FC3410 (Guangzhou Huayu Chemical Co., Ltd.) 1.5%;
