Care of knitted fabrics
Due to the diversity and quality differences in knitted products, the points to be considered during maintenance vary from product to product. The most basic problems that users encounter in terms of performance in knitted products are the inability to maintain dimensional stability, snagging and pilling.
Knitted products are preferred because they adapt to the body due to their looped structure, move with the body and are comfortable. However, this flexibility feature causes knitted products to not maintain their dimensions. Although double-plate knitted fabrics are more stable, users complain of shrinkage, stretching and deformation of knitted textiles.
Knitted products are generally easy-care products and are washed frequently, so various washing instructions are recommended so that they can be washed in washing machines without deterioration. For some products, the instructions even include drying in the dryer. However, generally, knitted products shrink more in the dryer compared to air drying. Lay-drying is the best way to keep their shape. Hanging drying may cause release due to the weight of the product itself. Dry cleaning is the best method for maintaining the dimensions.
Besides the release and shrinkage, another problem observed in knitted products is the loosening of the fabric with the effect of washing. The side seams of the garment may turn to the front or the back, and the hems may become warped. Especially knitted viscose products It is extremely resistant to washing. The iron holding properties of knitted fabrics are quite good as the yarns can move easily.
High weight products wrinkle less than low weight products. Double-plate knit products and products made from low-twist yarns are prone to pilling. Pilling poses a greater problem for knitted fabrics made of resistant synthetic fibers. Since viscose fiber is a weak fiber, it is more difficult for the beads to adhere to the surface, but after repeated washings, pilling may be observed in the product.
Care of viscose fabrics
When using viscose products, there are many issues to be considered in terms of maintenance. The low wet strength of viscose makes it unstable and shrinks or releases when wet. Routine washings cause loose shrinkage in viscose fabrics. For this reason, textiles produced from viscose fiber require dry cleaning or very delicate hand washing in order to maintain their size and shape. With various finishing support, viscose fabrics can be washed in the washing machine and the shrinkage values can be kept at 3%.
On the other hand, HWM (high wet modulus) rayon is easily machine washed like cotton and dried in the dryer. Another point to be considered is that the dyestuffs applied to viscose are sensitive to moisture. When the fabric comes into contact with moisture, the dyestuff migrates to the wetted area and forms a drop-shaped ring (stain) on the fabric. In order to eliminate this, the entire garment must be immersed in water, which reduces the strength of the viscose.
As viscose fabrics are used, they deform, lose their shine and become loose due to abrasion and wear out. Yellowing is another problem encountered in white and light colored fabrics. This problem can be solved by bleaching, and the use of chemicals damages the viscose fabric. Apart from these, pilling is observed in viscose-containing blends.
Viscose fabrics made of short fiber and low twist yarns wear out during wear. These fibers come together to form beads on the fabric surface. In products with viscose-synthetic blends, the fabric may melt at high temperatures, so care should be taken that the ironing temperature is not too high.
Dry cleaning is recommended for the best results for textile products made of viscose. If washing is done in the washing machine, problems such as shrinkage and loss of shape are encountered. For this reason, the washing instructions of viscose products often contain the phrase "dry clean only". Before washing, the washing instructions of the garment should be checked and the maintenance process should be done accordingly.
Viscose clothing should be kept away from moisture during use, and acid and alkaline substances should be avoided. Precautions should be taken against water staining. Care should be taken when washing by hand and the water of the laundry should be wrung out very delicately. Drying should be done. Hang-drying can also be done if the clothes are not too heavy. The ironing temperature can be set to medium, if the product contains viscose - synthetic content, it should be adjusted according to synthetic.
Features and problems of viscose products related to washing and drying
The most obvious disadvantage of viscose fiber, which we see everywhere in daily use, is that it is badly affected by the washing process and even increases the maintenance cost as a result of only dry cleaning is recommended for this type of products. The domestic washing process carried out in automatic washing machines causes many damages to products made of viscose such as shrinkage, release, may turn, wrinkling, pilling and abrasion.
Considering this way and considering the variety of uses, it will be very advantageous to wash viscose in washing machines. Thus, products with 100% viscose or high viscose content will be washable in washing machines.
Based on the benefits of washing viscose in washing machines, washing experiments were carried out on viscose fabrics with different characteristics made of various yarn and knitting types in fully automatic washing machines and the washing effects were examined. Due to the deterioration of viscose products with the effect of washing, the washing conditions have been determined to be very sensitive.
Under the same conditions, it is anticipated that blends such as viscose/lycra, viscose/cotton, viscose/polyester, which are widely available in the market, can also be washed without being damaged, since viscose is more sensitive to washing. Despite the sensitive conditions, it is expected to encounter problems such as dimensional change, shape change, loss of strength and pilling after repeated washings in viscose fabrics.
