Hongtu chemical: application of chemical fiber hydrophilic silicone oil 6159b

2020-04-28 3896067

Application of modified hydrophilic silicone oil 6159b
Product introduction:
Polyester, nylon and other textile fabrics are required to have excellent hydrophilicity, soft and fluffy hand feeling. The hydrophilic silicone oil of chemical fiber on the market can not be considered at the same time. If the hand feeling can meet the requirements, the hydrophilicity is poor, the hydrophilicity is good, and the hand feeling is poor. In view of this situation, the company has developed a new chemical fiber silicone oil of terpolymer silicone copolymer, which can meet the requirements at the same time It is mainly used for hydrophilic, fluffy and smooth finishing of nylon, polyester and other textiles.

Anion resistant stability:
The chemical fiber hydrophilic silicone oil 6159b was prepared with tap water as 40g / L sample solution, and anionic surfactant was added in a certain proportion. It was placed at room temperature for 10min, and placed in a constant temperature water bath at 40-80 ℃ for 30-60min to observe the phenomenon.

It can be seen from table 2, table 3 and table 4 that chemical fiber hydrophilic silicone oil 6159b has good stability of temperature resistance and anion resistance.
Product application effect:
Process formula and conditions
Fabric: polyester, nylon knitted fabric
Dip rolling method:
Chemical fiber hydrophilic silicone oil 6159b: 30g / L
Process: dip rolling (one dip and one roll, rolling margin 75% - 85%) → setting (170 ℃, 80s) → moisture regain (20-30min) → comparison of hand feel and hydrophilicity.
hand valuation
The evaluation consists of more than three people in a group, and the tactile evaluation is the best at level 5.

It can be seen from table 5 that the hand feel of chemical fiber hydrophilic silicone oil 6159b is better than that of general hydrophilic silicone oil.
Hydrophilicity test
Put the finished fabric (after full moisture return) on the table, drop a drop of water 2cm above the cloth surface with buret, and start timing. When the water drops gradually change from reflective to non reflective watermark, stop timing and measure 6 points to take the average value.

It can be seen from table 6 that the hydrophilicity of chemical fiber hydrophilic silicone oil 6159b is better than that of general hydrophilic silicone oil.
Product performance summary:
? give nylon, polyester and other textiles excellent fluffy and soft smoothness. ? smooth hand feel, low yellowing, no effect on color. ? it has good hydrophilicity and can be repaired. ? the treated fabric has certain antistatic property. ? good stability, no roller sticking. ? it can be used alone or in combination with other softeners.
Product precautions:
? the residual alkali and instability of textiles and the pH value in water will affect the finishing effect, which must be cleaned before finishing.
? the water used for working fluid shall be tap water ≤ 200ppm, and the ground water or river water shall be treated and reused.
? pay attention to the use in the rolling groove: when there are many burrs, pay attention to the refueling and cleaning of the rolling groove.
? this product is a weak cationic product. If coating, adhesive and other anionic products are used in the chemical tank, the re chemical material shall be cleaned.
Although softener emulsions are compatible with most cationic and nonionic auxiliaries, for compatibility purposes, compatibility must be tested before mixing. The stability of emulsion will also be affected under extreme conditions.
