Problems solved by technology

However, the above-mentioned Raschel blankets cannot meet the needs of the market, and since the acrylic Raschel blankets are woven by acrylic staple fibers after spinning, limited by the spinning technology, the current domestic common Raschel blankets can only do Above 1.67dtex, if the fiber is lower than 1.67dtex, it is difficult to spin, and a large number of wool particles are likely to be produced. The yarn strength is too low, and it cannot be woven on the warp knitting machine. At the same time, the cost of the blanket is too high due to the need for spinning to weave.
Even the cotton Raschel blanket produced on the double-needle bed Raschel warp knitting machine often needs to be cut and then finished. In the finishing, the pile is sorted by a brushing machine. Because the twist of the cotton yarn is large and the pile Shorter, the brushing machine cannot fully open the pile but can only open a small part, and the softness of the blanket made in this way is poor

Abstract

The invention provides a raschel carpet and a producing method thereof which relates to a raschel carpet produced by a single neilbed tricot machine that terylene is used as raw material. The method includes steps as follows: using 83-333dtex terylene low elastic net yarn as a felted yarn raw material and 56-111dtex terylene FDY as a bottom yarn for knitting on a weft knitting fur machine, thermal finalization; fluffing on front; terylene dyeing or printing; post treatment and front lustre finishing; shearing; reverse surface fluffing; and thermal finalization. The carpet is knitted by using the single neilbed tricot machine and the produced grey cloth needs not slitting that lead to increase productive efficiency greatly and reduce knitting cost. The felted head yarn of the knitted grey cloth is an extensive yarn, fibre in the yarn is fully washed into single fibre state in post treatment. The carpet provided by the invention has characteristics of super soft, filling power, better warmth retention property and exquisite style.

Description

technical field [0001] The invention relates to a raschel blanket and a production method thereof, in particular to a raschel blanket produced by a single needle bed warp knitting machine with polyester as raw material. Background technique [0002] Before the present invention proposes, the popular chemical fiber and cotton Raschel blankets on the market are all produced on the double-needle-bed Raschel warp knitting machine. Around 300 rpm. Production rates have been low and there hasn't been much change in feel and style. Along with the raising of consumer's living standard, the market urgently needs a kind of feel soft, comfortable, the Raschel blanket with low price. However, the above-mentioned Raschel blankets cannot meet the needs of the market, and since the acrylic Raschel blankets are woven by acrylic staple fibers after spinning, limited by the spinning technology, the current domestic common Raschel blankets can only do Above 1.67dtex, if the fiber is lower t...
