Fabric softening influence factors and solutions

⑴ achieve their hand
Soft finish soft style with customer requirements differ, such as soft, smooth, fluffy, soft waxy, oily, dry slippery, use of different softener based on different styles. In the film, the film has a different structure softener, softness, bulkiness, slip, yellowing situation, etc. Effects of different absorbent fabric. In silicone oil, modified silicone oil properties of different modified genes are different, such as silicone oil, hydroxy silicone oil, epoxy-modified silicone oil, carboxyl-modified silicone oil and the like properties are different.

⑵ yellowing discoloration
In the film, the cationic film soft good, feel good, easily adsorbed on the fabric yellowing discoloration, hydrophilic effect. Amino silicone oil is currently the most widely used silicone oil, amino cause yellowing discoloration. When the emulsion polymerization is sometimes used as a cationic surfactant as emulsifier 1227,1831,1631, these emulsifiers will produce yellowing. When using an emulsifier different silicone emulsion, the "stripping effect" is different, will cause the peel color and light color under different circumstances, has been part of discoloration.

⑶ fabric hydrophilic decline
After the film is generally a lack of structural problems and the use of silicone film forming absorbent gene, as well as closed-hydroxy cellulose fibers, wool on the carboxyl, amino, etc. These absorbent absorption center causing decreased.
Treatment: should be used wherever possible anionic, nonionic, film and the hydrophilic type of silicone oil.

⑷ dark spots
Caused reasons:
① When the oil before treating fabrics not go to the net, at the staining oil color darker.
② dyeing bath mixture too much foam, foam and flower sweater, dyes stick to the fabric.
③ defoamers floating oil caused a dark oil spots.
④ vat of tar-like substance into the fabric.
⑤ dye aggregation from dark spots in different situations.
⑥ Quality excessive calcium and magnesium ions combine with the dye stick to fabric and other reasons.
Treatment methods: ① treatment plus time to finish before scouring. ② dyeing auxiliary low-foam, no foam additives. ③ defoamers select varieties easily floating oil, add chelating agents to improve water quality, increase solubilization dispersant anti-dye aggregation. Timely and clear cylinder cylinder washing agent tank clean.

⑸ shallow spots
Caused reasons:
① pre-treatment is uneven, and some poor parts of the capillary effect, have some repellent dyeing, with the exclusion staining substances. Cloth with calcium soap, magnesium soap before handling or satin uneven.
② semi uneven drying.
③ cloth stained with sodium sulphate, soda ash and other solid undissolved.
④ dyed fabric before drying drops of Sheung Shui.
⑤ was softening after dyeing auxiliaries and other stains when finishing tape.
Treatment: strengthening before handling, pre-treatment chemicals must be selected not easy to form calcium and magnesium soap, thorough pre-treatment must be uniform (which is scouring agent, penetrating agent, chelating dispersant, mercerizing penetrant select relevant). Sodium sulphate, soda ash, etc. must be of good into the cylinder and the need to strengthen production management.

⑹ reason caused by alkali spot: after pre-treatment (such as bleach, silk) to the base without a net or uneven, resulting in plaque produce base.
Approach: the need to strengthen to a base pretreatment step of the process.

⑺ softener stains
Reasons: poor film of material, there are massive adhered to the fabric softener. After the film of the material too much foam in the cylinder when the cloth, fabric softener foam tape stains. Poor water quality, high hardness, water impurities and binding lectin on the fabric softener. Cloth with anionic species, in the soft processing, and combined into a cationic softener stains or cloth with alkali, so softener cohesion. Softener different structure, causing some softening into slag from emulsified state was adhered to the fabric, and so at higher temperatures. Cylinder original tar-like substance falling softener stick to the fabric.

⑻ silicone oil stains
Reasons: oil less than neutral PH value, especially with the base, causing the silicone oil demulsification floating oil. Treatment baths poor water quality, high hardness, silicone oil in> 150PPM hardness of water floating oil easily. Problems include poor quality silicone emulsion (emulsifier select poor, poor emulsification process, too emulsified particles, etc.), intolerance cut. Select the shear resistance, electrolyte resistance, resistance to change PH silicone oil, but be careful of silicone oil usage and the environment, but also consider the election hydrophilic silicone oil.

⑼ fluff poor
Raising poor with raising machine operations (such as tension control, pile roller speed, etc.) are closely related. The softener (commonly known as wax), the control fabric dynamic and static coefficient of friction is the key, so raising softener preparation is the key, if softener poor, a direct result of poor fluff.
