  • Heavy-duty machines often provide a range of needle choices. For light fabrics, slender needles like sizes 60/8 or 70/10 are appropriate, causing minimal puncture damage. Thicker fabrics, however, require heftier needles that can pierce through without bending or breaking. Moreover, specialized needles, such as ballpoint for knits or sharps for silks, further optimize the sewing process, tailoring the needle’s design to the fabric’s unique characteristics.

  • When shopping for a heavy duty sewing machine from China, it's important to consider your specific sewing needs and preferences. Look for a machine that offers the features and capabilities you need for your projects, whether you are sewing garments, home decor items, or quilts. You may also want to consider factors such as the size and weight of the machine, as well as the reputation of the manufacturer.

  • This is a huge concept for boating enthusiasts or anyone who needs to transfer their sewing machine from place to place. Most walking foot machines are roughly 35-40 pounds, depending on the size (7” or 9” gate) of the machine. Feel free to take your walking foot sewing machine anywhere as it’s easy to grip underneath the head of the machine. There are many cases available for this type of sewing machine as well.

  • Answer: hot water solution method: because HPMC is not dissolved in hot water, so the initial HPMC can be evenly dispersed in hot water, then quickly dissolved when cooling, two typical methods are described as follows:
    1) Put the required amount of hot water in the container and heat it to about 70℃. Under the slow stirring gradually add hydroxypropyl methyl cellulose, HPMC began to float on the surface of the water, and then gradually form a slurry, the slurry cooling under the stirring.
    2) Add 1/3 or 2/3 of the required amount of water into the container, and heat to 70℃, according to the method of 1), disperse HPMC, prepare hot water slurry; Then add the remaining amount of cold water to the hot slurry, stirring and cooling the mixture.
    Powder mixing method: HPMC powder and a large number of other powdery material ingredients, mixing fully with a blender, then add water to dissolve, HPMC at this time can dissolve, and do not stick together, because each small corner, only a little bit of HPMC powder, water will dissolve immediately. - Putty powder and mortar production enterprises are using this method. [Hydroxypropyl methyl cellulose (HPMC) is used as thickening agent and water retaining agent in putty mortar.]
