Abstract:In order to improve the draft combing quality of a straight carding machine，learning from the long linen spinning process，a new type of straight carding process of “plane needle curtain-auxiliary splint-plane needle curtain”，which is suitable for the automatic system of silk spinning is designed.In the process，a straight carding mechanism is designed，and the main parameters such as the card clothing and pin type for four plane needle curtain of straight combing area，the density of needle/tooth，the work area length of plane needle curtain and auxiliary splint，the action number of pin，and the carding speed of plane needle curtain.The “carding curtain-pin-air” model is established by using the fluid simulation software to analyze the influence of the carding speed on the air flow in the combing area and determine the parameters of the plane needle curtain and pin.It is pointed out that the new straight carding process for silk spinning，elastic card clothing and low and medium carding speed are used for A and B plane needle curtain，metal card clothing and high carding speed are used for C and D plane needle curtain，which can combine appropriate density and action number of pin to reduce the carding loss，avoid airflow disturbance，not affect the carding efficiency，and meet the requirements of automatic and continuous production of straight carding.
Key Words:silk spinning；circular combing；straight combing；plane needle curtain；combing area；card clothing；pin；airflow distribution
