The "hair length" of bath towels is usually quantified by the "loop height" (the length of tissue that extends out of the loop) in textile technology. The difference not only affects the tactile and visual texture, but also is deeply related to water absorption, durability, care difficulty, and scene adaptability. For hotel linen procurement, the selection of hair length needs to be comprehensively considered based on customer positioning, washing frequency, environmental characteristics, etc. The following analysis is conducted from a professional perspective:

1、 Long looped bath towel (looped height 3-5mm and above): luxury experience and performance limitations coexist

The core advantage of long looped bath towels lies in their "three-dimensional fluffy structure": the coils are longer and naturally stretched, and the surface area of a single fiber is significantly increased. When in contact with moisture, it can quickly absorb moisture through the "capillary effect", and its water absorption is 30% -50% higher than that of ordinary short looped bath towels (laboratory data shows that high-quality long looped bath towels can absorb 100ml of surface moisture within 10 seconds). This characteristic makes it highly favored in high-end hotels, hot spring resorts, and other scenes that emphasize a "luxurious touch" - when in contact with the skin, the fluffy loops can form a "buffer layer" to reduce friction, especially suitable for sensitive skin customers.

But the requirements for raw materials and craftsmanship for long haired loops are extremely high:

• Raw material restrictions: Long staple cotton with a length of ≥ 38mm (such as Egyptian long staple cotton, Pima cotton) or high-strength bamboo fiber must be used. If short fibers (such as ordinary fine staple cotton) are forcibly made into long loops, it is easy to cause "shedding" due to fiber breakage (according to industry standards, the shedding rate of qualified products should be ≤ 0.5%, while the shedding rate of low-quality short fiber long loops can reach 3% or more).

• Process dependence: High density organization (warp density ≥ 200 strands/inch) is required to fix the loops, otherwise "coil lodging" (i.e. entanglement and clumping of loops) may occur during washing, and the fluffiness may decrease by 40% after 30 industrial washes.

• Shortcomings in nursing: Long haired loops are prone to residual moisture inside, and in environments with humidity greater than 60% (such as the Southern Plum Rain Hotel), the drying time is 2-3 hours longer than short haired loops. If not thoroughly dried, it is easy to breed mold (especially when hotel linens are stored in a centralized manner); And it is necessary to avoid high-temperature drying (>60 ℃ can cause fiber brittleness), which increases washing costs.

2、 Short loop towel (loop height 1-2mm): a balance between durability and practicality

The short loop towel has a "tight and flat" appearance due to the tight attachment of the coil to the ground tissue, and its performance advantages are more suitable for high-frequency use scenarios:

• Outstanding durability: The coil is short and evenly stressed. When repeatedly rubbed by an industrial washing machine (at a speed of 800 revolutions per minute), the fiber breakage rate is 60% lower than that of long looped towels (tests have shown that short looped towels can withstand more than 100 standard washes while maintaining structural integrity, while long looped towels usually show obvious pilling after 60-80 washes).

• Convenient care: The tight structure allows for more thorough dehydration (moisture content can be reduced to below 15%, while long haired loops require 25%), reducing drying time by 30%. It is suitable for economy hotels and chain hotels with a daily turnover of more than 500 sets of linen, and can improve washing efficiency.

Wide scene adaptation: In humid areas (such as coastal hotels) or "instant use" scenarios such as swimming pools and gyms, short hair loops are less likely to produce odors due to residual moisture; The short loops that have been partially treated with the "velvet cutting process" (i.e. cutting off the top of the loop to form a flat velvet surface) have a silky smooth feel, balancing the durability of the short loops with the delicacy of the long loops. They are often used as a "cost-effective choice" for mid to high end hotels.

Its limitations are mainly reflected in its water absorption and tactile sensation: the surface area of short hair loops is small, the water absorption rate is slow (it takes 15-20 seconds to absorb the same amount of water), and if the ground tissue is too dense and the loops are too short (<1mm), it may produce a "sandpaper feel", and the short fibers need to be removed through the "combing process" to ensure a soft tactile sensation.

3、 The core decision-making logic of hotel procurement: Mao Chang ≠ "the longer the better"

1. Customer positioning: High end hotels (such as five-star hotels) can choose 3-4mm long hair loops (paired with long staple cotton materials) to convey a sense of quality through a fluffy touch; Mid end business hotels recommend 2-3mm short hair loops to balance experience and cost; Economy hotels prioritize 1-2mm short hair loops, emphasizing durability and washing efficiency.

2. Testing indicators: When purchasing, the supplier is required to provide a "loop height testing report" (measuring coil length through a microscope), "shedding rate test" (GB/T 22798 standard), and "washing size change rate" (long loops are prone to shrinkage, qualified products should be ≤ 3%).

3. Environmental adaptation: Avoid long hair loops larger than 4mm in humid areas in the south, and can be relaxed to 5mm in dry areas in the north. Hot spring hotels prioritize long hair loops and use daily high-temperature disinfection processes to suppress mold, as their customers are more concerned about water absorption.

In summary, the essence of towel hair length is the art of matching performance with the scene. Hotel linen procurement needs to break away from the misconception that "long hair loops are high-end", and combine with its own operational needs to evaluate the entire chain of raw materials, processes, and care in order to select high-quality products that meet both guest experience and cost control.
