Water Soluble Fabric Is So Famous, But Why?

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.

Is Water Soluble Fabric Eco friendly?

It can be rapidly denatured, decomposed, and degraded into low molecular compounds by itself through the action of natural factors, and has the effect of improving the land. It has been recognized by environmental departments in Europe, America, Japan, and other countries. Because of its environmental protection properties, it has been widely valued by developed countries around the world.

What Are Water-soluble Fabric Stabilizers?

It is mainly a reagent that keeps polymer plastic, rubber, and synthetic fiber stable and prevents its decomposition and aging. It is perfect for embroidery, letter combinations, quilting, lace work, buttonholes, applique, etc. It is easy to use and suitable for any project.

Role of water-soluble stabilizers.

The role of stabilizers is to increase the stability of solutions, colloids, solids, and mixtures, which can slow down the reaction, maintain chemical equilibrium, reduce surface tension, prevent photothermal decomposition or oxidative decomposition, etc... Broadly speaking, chemical stabilizers come from a wide range of sources, mainly according to the design purpose of the formula designer, can be flexible to use any chemical to achieve product quality and stability.

How Do You Use Water Soluble Fabric Stabilizers?

The first method is to submerge the item in warm water for 2-3 minutes while rubbing the stabilizer to dissolve it. The second method is to rinse the item under running water at an angle and then wipe the area of stabilizer residue again. 

How Does Water Soluble Stabilizer Work?
