Water-soluble fabric refers to the fabric that can dissolve in water or slowly hydrolyze into water-soluble molecules (or compounds) in water, which is a valuable functional differentiated fabric. With the increasing awareness of people's environmental protection, the application of non-toxic, non-polluting, and hydrolyzable water-soluble fabrics has been gradually popularized, and the research and development of such fabrics have also been deepened, and its application is very extensive.

What Is Water Soluble Fabric?

What Is Water Soluble Fabric?
Water-soluble fabric, also known as non-woven embroidery fabric, is a material that melts when it meets water. Water-soluble fabric refers to the water-soluble PVA staple fiber as the main raw material. It is a new type of material that can be dissolved in water at room temperature and is a new type of water-soluble functional nonwoven fabric. It is a new type of water-soluble functional nonwoven fabric.

It is mainly used as the backing material for embroidery and also used for making decorative paper flowers. The existing water-soluble fabric is of low quality, its strength is poor and it is easy to be torn off, so the products made of existing water-soluble fabric are not used for a long time. At the same time, the existing water soluble fabric production and processing production process steps are complicated and the production cost is high.

How Are Water-soluble Nonwovens Made?

The current production of polyvinyl alcohol is polyvinyl acetate in the role of methanol or sodium hydroxide alcoholysis reaction and obtained. PVA fiber is divided into high alkali alcoholysis and low alkali alcoholysis of two different production processes.

High reduction alcoholysis method.

The polyvinyl acetate methanol solution used for alcoholysis is preheated to 45 a 48°C and then sent to the mixer by pump with 350 g/L aqueous sodium hydroxide. After thorough mixing, it is sent into the alcoholysis machine. After alcoholysis, lumpy polyvinyl alcohol is generated, which is then crushed and extruded to separate polyvinyl alcohol from the alcoholysis residue. The resulting solid material is further crushed and dried to obtain the desired polyvinyl alcohol. The residue from the press and the steam from the dryer are combined and sent to the recovery section to recover methanol and acetic acid. 

Low alkali alcoholysis method.

The process is similar to the high alkali alcoholysis method. The methanol solution of polyvinyl acetate preheated at 40~45℃ and the methanol solution of sodium hydroxide are pumped to the mixer respectively. The mixed material is sent to the conveyor belt of the belt alcoholysis machine. The alcoholysis reaction is completed after a certain period of time at resting state. The lump of polyvinyl alcohol is then dropped from the end of the belt machine, crushed, and put into the washing kettle to be washed with the methanol solution that removes sodium acetate. Then it is put into the intermediate tank and then sent to the separator for continuous solid-liquid phase separation. The resulting solid is dried to the desired polyvinyl alcohol and the residual liquid is sent for recycling.

The Feature of Water-soluble Nonwoven Fabric.

  • The excellent water solubility, hydrophilicity, and moisture absorption of water-soluble fibers have been applied to various fields and are very promising functional differentiated fibers.

  • The main feature of the water-soluble fabric is its water solubility, and the fabric can be dissolved in hot water very well. It can be dissolved in high temperature, medium temperature, and low temperature water respectively to meet the different product needs of customers.

  • The strength and hardness of water-soluble fabric are very good, with excellent impact resistance. Of course, the water-soluble fabric also has excellent weather resistance, even if long-term exposure to the sun, its strength loss is not large.

  • It can degrade itself in the natural environment, and the bags made of it will not be as indecomposable as plastic bags.

  • Water-soluble fibers are used for sizing the warp yarns of fabrics, with the advantages of uniform sizing, stable chemical structure, good corrosion resistance, simple and easy process.

  • Water-soluble PVA fiber has ideal water solubility temperature, strength, and elongation, good acid resistance, alkali resistance, dry heat resistance. Moreover, it is non-toxic after dissolving in water, and the water solution is colorless and transparent, which can be decomposed naturally in a short period of time without any pollution to the environment, and it is a 100% green product.

The Applications of Water-soluble Nonwoven.

  • The product and its compound products can be used in embroidery, medical treatment, nursing protection, surgery and disease prevention and treatment, home textile field, etc. It can be hydrolyzed and degraded after use, and has extremely broad application prospects.

  • Medical and sanitary materials made of water-soluble nonwoven fabrics have the characteristics of easy hydrolysis and no pollution. They are commonly used as disposable surgical gowns, caps, bibs, adhesive gauze, surgical dressing materials, medical bed sheets, work clothes, work caps, etc. After disposable use, it is dissolved in hot water at about 90℃.

  • Companion spinning and weaving: water-soluble PVA fiber is used as an intermediate fiber to blend with other fibers, and the water-soluble fiber is dissolved after textile processing to get high-grade textiles, increasing the gap between wool fibers, making wool fabric lighter, softer, more fluffy and warmer.

  • Water-soluble fiber and cotton, hemp, and other natural fiber blending can change the internal structure of the yarn, increasing the gap between the fibers and capillary pores inside the yarn, thus changing the breathability of the fabric.

  • Production of microfiber: water-soluble PVA and nylon, polyester, polyethylene, polypropylene and other composite fibers, after stretching treatment, and then wash away the PVA, you can get superfine fibers.

  • Application in embroidery base fabric: On the base fabric, embroider the desired pattern, then dissolve the PVA component, so that the fabric to obtain a beautiful pattern. The water-soluble nonwoven fabric is embroidered and then the lace is removed, making a breakthrough in the traditional lace manufacturing industry.

  • Application in the paper industry: water-soluble fibers are used as binders for paper copying to improve the strength and toughness of paper, which greatly improves the fracture and tear strength, folding resistance, and printing surface strength of finished paper

Types of Water-soluble Nonwoven.

Cold water soluble nonwoven fabric.

Environmental protection cold water soluble non-woven bags is a green product, tough and durable, beautiful shape, good breathability, can be used repeatedly. From the release of plastic restrictions, plastic bags will begin to gradually withdraw from the packaging market of goods, replaced by the ability to repeatedly use on the cold water soluble non-woven shopping bags.

Water soluble cotton.

Water-soluble cotton raw material is PVA fiber, which is specially developed for three-dimensional embroidery. It is the ideal lining material for stereoscopic embroidery, 3mm thick, dissolves in room temperature water without leaving residue, and environmental protection products. The traditional paper liner can not meet the high-end product development of three-dimensional embroidery, while water-soluble cotton is made of imported raw materials, which can be dissolved by tap water at room temperature and can solve the problem of dissolution and environmental protection.
