  • Remove lint, dust, and debris from the machine and bobbin area using a brush and compressed air.

  • This thing is heavy – weighing close to 40 lbs! So you definitely don’t have to worry about it walking around on you.

  • You are going to use the heavy duty sewing machine for a long time, so you need to choose a versatile sewing machine and that can sew perfectly both thicker and thinner materials. This way, you won't be constrained to working with just one type of material all the time. Artists need to have a lot of freedom when it comes to the creative process and this way you won't find yourself in the situation where you need to buy another sewing machine just for working with thinner materials.

  • First and foremost, durability is crucial. Leather and canvas are tough materials that can put a lot of strain on a sewing machine. Look for a machine with a strong, sturdy frame that can withstand the heavy-duty use. Metal frames are usually more durable than plastic ones, so keep that in mind when making your selection.

  • Answer: HPMC serves three functions in putty powder: thickening, water retention, and facilitating construction. It does not participate in any chemical reactions. The reasons for bubble formation are as follows:

  • HEC is a cellulose ether that is synthesized by the reaction of cellulose with ethylene oxide, followed by the hydroxyethylation of the cellulose backbone. The first step in the production of HEC involves the extraction of cellulose from wood pulp or cotton. The cellulose is then reacted with ethylene oxide in the presence of an alkaline catalyst to form hydroxyethyl cellulose.
  • Environmental friendliness is another advantage of HPMC. Being derived from renewable resources, it contributes to sustainable practices, making it an attractive choice for many industries.
