This helps to improve the strength and abrasion resistance of the yarns, making them more durable and suitable for weaving and other textile processes. The powder also enhances the washability and overall quality of the finished textiles, ensuring that they maintain their appearance and performance over time.
    Another advantage of using HPMC in wall putty is its resistance to microbial growth, which helps to increase the longevity of the finished surface

    HPMC, which stands for Hydroxypropyl Methylcellulose, is a widely used chemical compound with a diverse range of applications across various industries. It is a type of cellulose ether, derived from natural cellulose, a primary structural component found in plant cell walls. The production of HPMC involves two main raw materials cellulose and two chemical modifiers - hydroxypropyl and methyl groups. The primary source of cellulose is typically cotton lint or wood pulp, both rich sources of this naturally occurring polymer. These raw materials undergo a series of chemical processes to create HPMC. Firstly, the cellulose is treated with alkali, usually sodium hydroxide, to create a cellulose alkali solution. This step, known as alkalization, makes the cellulose more reactive. Next, the alkali cellulose is reacted with a propylene oxide and methylation agent, typically in the presence of a solvent like acetone or ethyl alcohol. Propylene oxide adds hydroxypropyl groups to the cellulose structure, while methylation is achieved through the action of methyl chloride. These modifications alter the properties of cellulose, imparting it with water-solubility and other desirable characteristics These modifications alter the properties of cellulose, imparting it with water-solubility and other desirable characteristics
