- Another benefit of a twin needle sewing machine is its efficiency. With two needles stitching at the same time, you can save time and complete your projects faster than with a single needle machine. This can be especially useful for those who sew in large quantities or have tight deadlines to meet.
The significance of sewing machine chains extends beyond mere efficiency. They have contributed to the cultural and social shifts within the textile industry. With the ability to mass-produce garments, sewing machine chains have facilitated the rise of the fast fashion industry. This phenomenon has made fashionable clothing accessible to broader audiences, but it has also raised questions about sustainability and ethical labor practices. The ease of production has led to increased demand for cheap, quickly made garments, often at the expense of quality and the well-being of workers in developing countries.
1. Select a Stitch Most sewing machines will allow you to select either a straight stitch or a zigzag stitch when using a twin needle. A straight stitch is often used for hems, while a zigzag can add decorative flair. Avoid stitches that may cause overlapping, as this can lead to jams.
In addition to practical applications, chain stitches are also widely used in decorative sewing. They lend themselves perfectly to embroidery, quilt making, and patchwork projects. Crafters often employ chain stitching to create intricate designs, borders, and motifs, elevating the aesthetic value of their creations. The stitch can be easily manipulated to form curves and shapes, providing almost endless possibilities for artistic expression.

1: What is HPMC?
Hydroxypropyl methylcellulose ( (Propylene glycol ether of methylcellulose) is a methylcellulose modified with a small amount of propylene glycol ether groups attached to the anhydroglucose of the cellulose. The dry product contains 19 to 30 per cent of methoxyl (-OCH3) groups and 3 to 12 per cent of hydroxypropyl (-OCH2CHOHCH3) groups. HPMC can be derived from tree fiber or cotton fiber.
2: How HPMC is made:
The cellulose ethers are manufactured by a reaction of purified cellulose with alkylating reagents (methyl chloride) in presence of a base, typically sodium hydroxide and an inert diluent. The addition of the base in combination with water activates the cellulose matrix by disrupting the crystalline structure and increasing the access for the alkylating agent and promotes the etherification reaction. This activated matrix is called alkali cellulose (Kirk-Othmer, 1993). During the manufacture of HPMC alkali cellulose reacts with methyl chloride to produce methyl cellulose and sodium chloride. Side reactions of the methyl chloride and sodium hydroxide produce methanol and dimethyl ether by-products. The methylcellulose is then further reacted with the staged addition of an alkylene oxide, which in the case of HPMC is propylene oxide (Kirk Othmer, 1993 Dow, 2002). After this reaction, MC and HPMC are purified in hot water, where they are insoluble. Drying and grinding completes the process.
3: Chemicals agents and reactions:
The chemical reactions of manufacturing HPMC summerize as following:Over the past few years, the pricing of redispersible polymer powder has shown a trend of gradual increase, primarily driven by rising raw material costs and heightened demand in developing economies. Analysts predict that this upward trend may continue, albeit at a moderated pace, as the global economy stabilizes post-pandemic and construction activities ramp up.
