The influence factors of soft processing

1, can not due to feeling

Soft finishing with soft style customer requirements vary, such as soft, smooth and fluffy, soft waxy,oily, dry sliding, depending on the style of using different softeners. In the film, there are different structures of the softener film, its softness, bulkiness, smoothness, yellowing, effect of fabric aredifferent. In silicone oil, modified gene modified silicone oil properties are different, such as amino silicone oil, silicone oil, epoxy modified silicone oil, silicone oil and carboxyl modified properties aredifferent.

2, pale yellow

In the film, the film is soft, feel good good cation, easy adsorption on the fabric yellowing,discoloration, effect of hydrophilic. Amino silicone oil is the most widely used silicone oil, amino will cause discoloration yellowing. Emulsion polymerization, sometimes using cationic surfactants such as 1227, 1831, 1631 as emulsifier, the emulsifier will produce yellowing phenomenon. The use ofsilicone oil emulsification emulsifier, the stripping effect is different, will result in different conditionsof stripping and light color, is pale.

3, hydrophilic fabric decreased

The film is generally used to structure and silicone oil film after the lack of water and closed gene,hydroxyl, wool like cellulose fibers on the carboxyl and amino of these water caused by water dropscenter.

Treatment methods: silicone oil should be used as far as possible of anionic and non ionic film and hydrophilic type.

4, deep stain

Causes: the pretreatment of fabric oil did not go to the net, when dyeing oil color darker. The dyeingtoo much bubble bath, bubble and flower sweater, dye mixture stick on the fabric. The defoaming agent of floating oil caused by dark staining. The dye stained with tar like substance in the fabric.The dye aggregation in different situations and dark spots. The quality of calcium and magnesium ions excessive and dye binding dip in the fabric and other reasons.

Processing method: pretreatment with oil refining agent. The dyeing auxiliaries with low foam, no foam additives. The defoaming agent is not easy to choose floating oil varieties, improve water quality and chelating agent, dispersing agent and anti agglutination dye solubilization. With thecleaning agent to wash tank cleaning.

5, light spot

The cause of the pretreatment is not uniform, some parts of the hair dyeing effect is poor, which tocertain, with tropochrome material. With the cloth with calcium soap, soap or mercerized magnesiumis not uniform. The uneven drying of semi-finished products. The cloth stained with dissolved sulfate,soda ash and other solid. The dyed fabrics before drying to drop of water. Auxiliary stains stain softprocessing finishing belt.

Treatment methods: strengthen pretreatment, pretreatment agent selection must be easy to formcalcium soap, before treatment must be uniform and thorough (which is related with scouring agent,penetrating agent, chelating agent, mercerizing penetrant choice). Yuan Mingfen and soda ashmust be well into the cylinder and must strengthen production management work.

6, alkali spot

Causes: pretreatment (such as bleaching, Si Guang) after alkali net or uneven, resulting in alkalispot.

Methods: we must strengthen to the pre-treatment process of alkali.

7, softener stains

The causes: the film material is poor, there are massive adhesion to the fabric softener. Film materialafter the bubble too much, in a cylinder cloth, cloth with soft foam stains. Poor water quality, the hardness is too high, impurities and soft water agent with agglutination in the fabric. The cloth withanionic substances, in soft processing, combined with cationic softener into stains, or oil with alkali,the condensation of softening agent. Softener structure is different, some caused by softening agentfrom emulsified state into slag on the adhesion of fabric under high temperature and so on. The original cylinder tar like substances such as softeners on fabric fall stick.

8, silicone oil stains

Causes: cloth was not neutral pH, especially alkali, caused by silicone oil demulsification of floating oil. The bath water is too poor, too high hardness, hardness of >150PPM silicone oil in water easilyfloating oil. Poor quality problems including silicone oil emulsion (emulsifier, emulsifying process,poor poor choice of emulsion particles is too large, not resistant to shear). Selection of shear resistance, electrolyte resistance, oil resistance PH change, but should pay attention to the use of silicone oil and the environment, can also be considered hydrophilic silicone oil.

9, raising the poor

Fluff with poor pilling machine operation (such as tension control, raising roller speed etc.) are closely related. Softener (commonly known as the wax), control fabric dynamic, static friction coefficient is the key, so the preparation of fluff softening agent is the key, if the poor softener used,will be the direct result of poor pilling.
