This invention discloses an enhanced impurity removal and gentle carding process for machine-harvested cotton, belonging to the field of textile processing technology. The process includes four coordinated steps: pretreatment and feeding control, enhanced impurity removal in the licker-in area, fine carding in the cylinder, flatbed, and doffer areas, and cotton suction and negative pressure configuration. By controlling the lap weight to 380-420 g / m and the moisture regain to 7.0%-7.8%, increasing the licker-in speed to 920-980 rpm and using a low-blade, large-angle dust removal knife configuration, while simultaneously reducing the cylinder speed to 320-340 rpm and increasing the flatbed speed to 220-260 mm / min, and optimizing key spacing, this process achieves efficient removal of impurities from machine-harvested cotton while reducing fiber damage. This process solves the technical problems of low impurity removal efficiency, high short fiber content, and large quality fluctuations when the TC15-3 carding machine processes Xinjiang machine-harvested cotton. It reduces the impurity content of the sliver by 15-30%, the short fiber growth rate by 1-2 percentage points, and the nip removal rate by 10-20%.

The present invention relates to a combing machine (K) with several combing heads (1), wherein the combing heads (1) each have a gripper apparatus (2) through which a cotton strip (Wb) provided by a cotton roll (W) can be guided, further comprising a fixed (5) and a round comb (4) for combing out combed pieces from the cotton strip (Wb), a pair of tear-off rollers (6) for tearing off a fiber beard from the cotton strip (Wb) and for soldering the fiber beard to a fiber nap (Ff), wherein each combing head (1) is followed in the material flow direction by a take-off table (11), means for consolidating the fiber nap (Ff) into a nonwoven (V), and a belt funnel (41) for forming the nonwoven (V) into a fiber strip (F1 - F8). The invention is characterized in that each comb head (1) has a single pair of tear-off rollers (6), and that the take-off table (11) has a first rising section (12) onto which the fiber web (Ff) formed by the single pair of tear-off rollers (6) is guided to a continuously rotating pair of take-off rollers (8).

The application relates to the technical field of cotton spinning combing machine cylinder technology, and discloses a design method of the height of a cotton spinning combing machine cylinder tooth piece, which comprises the following steps: calculating the fiber roots of a cotton roll cross section, calculating the total area of the transverse fiber cross section in the cotton roll, calculating the fiber area on the cylinder tooth piece width during the combing process, and calculating the cylinder needle tooth height value; step 1: calculating the fiber roots of the cotton roll cross section; step 2: calculating the total area of the transverse fiber cross section in the cotton roll; step 3: calculating the fiber area on the cylinder tooth piece width during the combing process; and step 4: calculating the cylinder needle tooth height value. The corresponding tooth piece can be made according to the specific properties of the fiber, so that the problem of combing leakage can be effectively solved, and the combing effect on the fiber is improved.

This invention provides a glass fiber cotton winding device and method, belonging to the technical field of glass fiber cotton winding devices. Based on existing winding devices, it incorporates a guide at the feed inlet of the winding device. This guide directs the front end of the glass fiber cotton downwards to the inner side of the glass fiber cotton at the feed inlet. By providing a guide at the feed inlet of the glass fiber cotton winding device, this invention effectively solves the problem in existing winding devices where the front end of the cotton roll easily comes into contact with glass fiber cotton that has not yet entered the inner cavity of the roll, leading to winding failure and requiring manual intervention. This improves the stability and automation of the winding process.

This invention discloses a device for testing the water absorption performance of a novel cotton roll bandage, relating to the technical field of medical textile material testing equipment. It includes a long container and a reusable testing component. The reusable testing component is fixedly installed at the bottom of the long container, and includes a bracket fixedly installed at the bottom of the long container. This device integrates bandage water absorption rate testing, tensile water retention testing, torsional water retention testing, and composite stress water retention testing into a single device. The automated linkage design of the traction torsion component allows for automatic switching and precise linkage of tensile and torsional actions through preset tension rate, torsion angle, and linkage sequence via a controller. This eliminates the need to transfer samples between multiple devices, avoiding moisture loss and structural damage during transfer, while also reducing equipment space requirements and adapting to laboratory and production line testing needs.

The objective is to provide a three-layer or five-layer mattress futon and a method for manufacturing the same, which do not have machine stitching that penetrates the cover material, in order to simplify the comfort sewing process. [Solution] The three-layer or five-layer mattress futon of the present invention is characterized in that a core and a roll of cotton wrapping the core are sandwiched between a bag-shaped cover material made of an outer fabric and an inner fabric, the roll of cotton is compressed and stored in the cover material, and the cover material as a whole receives tension due to the elastic force of the core and the roll of cotton, thereby maintaining the position of the stored roll of cotton and the core. Therefore, comfort stitching is not required.
