Heavy duty sewing needles are incredibly versatile and can be used for a variety of projects, including

1. Singer Heavy Duty 4423 This machine features a strong motor, a stainless steel bedplate for smooth fabric feeding, and an array of stitch options. It’s a popular choice for beginners and experienced sewists alike.

On the higher end of the spectrum, advanced saddle stitch machines equipped with automation, higher speed, and additional features can range anywhere from $20,000 to $200,000 or more. These machines are designed for high-volume production and often come with features such as inline trimming, folding, and even digital printing capabilities, making them ideal for larger printing companies or commercial print shops.

At its core, the chain stitch machine operates on a unique mechanism that utilizes a single-thread system to create a flexible and durable stitch. Unlike conventional lockstitch machines, which utilize two threads, the chain stitch method allows for a variety of applications, from delicate fabric to heavy materials. The machine’s ability to produce a chain-like stitch makes it particularly advantageous for creating seams that require stretch and durability, such as in athletic wear and denim.

For hydroxypropyl cellulose (E 463), the identified NOAEL corresponded to the highest dose 6,000 mg hydroxypropyl cellulose/kg bw per day (by gavage). The most relevant feeding studies with HPMC (E 464) were performed in rats which tolerated up to 10%, corresponding to 9,000 mg test item/kg bw per day. Rabbits tolerated up to 7,500 mg HPMC/kg bw per day administered via the diet (30 day exposure) and dogs up to 1,500 mg HPMC/kg bw per day, in either case being the highest tested dosages. More studies were conducted using sodium carboxy methylcellulose (E 466). The most relevant ones were conducted in rats, with NOAEL values ranging from 4,500 to 9,000 mg test item/kg bw per day (in all cases the highest dose tested). In these studies, some effects (caecum and colonic enlargement, urothelial hyperplasia, nephrocalcinosis, diffuse epithelial hyperplasia in the urinary bladder) were observed, however, not considered of toxicological concern: the findings in the gastrointestinal tract were considered to be a consequence of the accumulation of poorly absorbed water-soluble material and the findings in kidneys and urinary bladder were attributed to the up to fourfold higher concentration of sodium in the test diet compared with the basal diet. In one further study, rats were daily exposed (gavage) to doses equivalent to 0, 500, 2,500 or 5,000 mg/kg bw per day. Animals treated with ≥ 2,500 mg/kg bw per day had soft and pale faeces, which was attributed to the presence of test material and not considered of toxicological relevance. In the absence of any other adverse effects, also for this study, the identified NOAEL was the top dose (5,000 mg/kg bw per day).

Due to its excellent mucoadhesive properties, HPMC gel is used in ophthalmic solutions to provide longer residence time on the ocular surface and improve drug absorption.
