    Tongmao? Chain Saw Protection Apron Chaps
        Tongmao? Chain Saw Protective Apron Chaps and Cut-retardant material is a high-tech fabric of polyester, kevlar,polyester and polypropylene fibers. The special structure of the fabric makes it easy for the saw chain to pull and to draw the fibers into the chain saw. Each fiber is built up of a lot of fine filaments to fill It is very important how the layers of the fabric are designed and sewn to form a protective pad and how the protective pads are sewn into the pants, chaps or leggings. Incorrect sewing of the fabric may bind it too hard to the garment and make it difficult for the chain to pull the fibers.
       If a running chain saw chain comes in contact with the Tongmao? jamming protective materials, the fibers and their filaments are pulled and drawn by the ehain into the chain saw and the fibers and their filaments will jam and clog the drive sprocket.

       Special fabrics have been developed for chainsaw clothing, and this development is still very active. Conventional fabric is useless at protecting against a running chainsaw, being immediately cut through.
        There is a real struggle between making a fabric proof against more violent impact, and making it light, flexible and comfortable enough for the user. Clothes which make the user too hot, or which prevent the user moving easily, are a safety problem in themselves. A worker suffering from heat exhaustion is not safe. Extra fabric layers can be added to clothing to improve cut resistance, but clothes which cannot be cut at all by a powerful saw are impractical, even with modern fibres. What is worse, saw and chain technology seems to be outstripping fabric technology. High power saws with aggressively cutting chains are almost impossible to protect against.
        A classification scheme has been developed in the EU to rate trousers, and fabric in general, for protection against cutting.

        The chain speed is specified in the manual for a chainsaw. Higher class trousers cost more and are heavier, so there is an advantage to choosing the trousers to match the saw.
        There are two standard types of trousers, type A and type C. Type A protects only the front of the legs, and can be supplied as chaps, worn over conventional work clothes, or as conventional trousers. Type C gives protection all round the legs and are almost always worn as ordinary trousers, not over another garment. Chaps are generally used for occasional, farm or       homeowner applications. Professional chainsaw operators would choose trousers for comfort and ease of movement, with fallers, ground workers and firewood cutters opting for class A trousers because of the low risk of being cut in the back of the leg. Climbers and tree surgeons would have to wear type C, as they will be cutting from a wider variety of positions. Type C trousers are, of course, highly insulating, and may lead to heat stress if worn for labour intensive operations such as firewood cutting.
        Chainsaw protective fabric works on a number of principles. The outermost layer can be made both tough and slippery, to protect against trivial damage which could compromise the filler material. Beneath this, long, loose fibres of ballistic nylon or Kevlar are laid in layers. When a saw contacts the trousers, the outer layer is immediately cut through but the nylon or Kevlar is drawn out and wraps around the saw's drive sprocket, locking it solid and halting the chain, limiting damage to the operator's leg. After stopping a saw, the trousers are scrapped, and the saw must be field-stripped to remove the fibres and allow it to run again. Chainsaw protective trousers in the EU must comply with EN381-5.

    Tongmao? chainsaw chaps meet the requirements of ASTM Standard for Leg Protection for Chain Saw Users (F-1897-2008). This standard requires that the chaps can stop a chain saw running at 2,750 feet/minute tested at both 45 degrees and 90 degrees to the longitudinal axis of the test sample, under controlled laboratory conditions. Compliance tests are performed by Underwriters Laboratories (UL) in accordance with ASTM F-1414, Measurement of Cut Resistance to Chain Saw Lower Body Protective Clothing. The performance requirements previously were 2500 feet per minute chain speed.
